The adaptation of Provo River wildlife to frequent human traffic
Erik Agle, 359 W 3950 N, Provo Utah 84604 Email: agle.erik@gmail.com
Abstract:
I conducted observations along several points of the Provo River of Provo, Utah.
Each point differed in its frequency of human traffic. Birds, reptiles, amphibians, and
mammals were identified at each point. The purpose of these observations was to
determine which particular animals have adapted to frequent human presence in
comparison to others. Each observation was conducted for an hour. Two observations at
each of the three locations were conducted, totaling two hours per spot. Wildlife sightings
were categorized and counted. It was determined that much of the local wildlife,
particularly birds, had become very tolerant of human neighbors without much trouble.
However, several animals, though still present in frequently-trafficked areas, were more
scarce as human exposure increased and had undergone more drastic behavioral
adaptations making their population more skittish. It was determined that speed and size
were influential variables in an animal’s ease of adaptation to humans.

The Influence of Temperature on the Migration of Mule Deer

Melissa.alvarez13@yahoo.com
Abstract
It seems the behavior of Mule deer (Odocoileus hemionus) is affected by the
seasons and the temperatures that come with the seasons. It seems the deer are farther up
in the mountains in the warmer seasons and seem to migrate down into the valley when
temperatures begin to drop. Studies will be made of the deer and the types and genders
and how often deer are sighted in the valley by Maple mountain. The number sighted will
be counted and how many of each gender and how many are doe or adults. With research
it will be looked up on what deer eat and where deer go when they leave the mountains or
if they leave just to find food and return. Since March is the beginning of spring the
number of Mule deer (Odocoileus hemionus) sightings will decrease due to instinct and
change to warmer weather.

Differing Heights of Plants as Influenced by Distance from Water Source, Provo River:
Provo, Utah, U.S.A

mn_andrews@yahoo.com
Abstract
I hypothesized that the height of plants is affected by the amount of water
provided, but more research had to be conducted before I could conclude the extent to
which a nearby water source affects the growth of certain plants. Experiments were
conducted around Provo River with local plants to show the differences of height in feet
and inches of these plants to show whether distance from a water source causes these
plants to grow taller. Samples of a plant species found around Provo River were
identified using a dichotomous key, and nine samples of this species of plant were
measured at varying distances from the river. Data of height versus distance from water
source were recorded in a table. It was determined that distance from a water source does
indeed affect the height to which certain plants will grow. It was found that plants of the
species and genus Ribes aureum, more commonly known as the golden currant, that
were closer to the Provo River were taller on average than plants of the same species that
grew farther away from the river.
Key words: Provo River, Ribes aureum, height, water source, distance.

Abstract:
I will conduct a study of food preference of birds in the Provo, Utah area hoping
to see a trend of which food preferred in the winter season. The experiment will be
conducted in a local Provo park on N. Birch Ln. and N 1200 E. I will place multiple bird
feeders in the area, each filled with a different type of food, seed, berry, etc. The bird
feeders will be checked and the food remaining measured periodically to see which food
has been eaten the most.
Litmus test properties of local lichen dyes compared to the pH-indicating properties
of the lichen species Roccella tinctoria: Provo, Utah, U.S.A.
Claire Asplund, 1813 Fugal Hall, Provo, Utah 84606. Email: claireasp@frontier.com
Abstract
I harvested 17 local lichen samples from Nunn Park in Provo Canyon and made
dyes from 12 of these specimens. I boiled each type of lichen in water for an hour and
separated the resulting dye into three cups, in which I altered the pH level of the liquid. I
then dyed pieces of wool yarn using each variation of the lichen dyes, and after letting the
yarn steep for a day, compared the resulting colors. Based on my observations, though
none of these local lichen samples yielded very bright or interesting dyes, each batch of
dye indicated a change of color correlating with a change of pH, confirming my
hypothesis that this is a general property of most lichen species, even though the Roccella
tinctoria, which is a lichen actually used in litmus paper, has a chemical makeup better
suited to indicating the pH of substances.
Key words: lichen, natural dyes, Roccella tinctoria, pH indicator, litmus paper.
Investigation of Budding and Blossoming on Deciduous Trees in
Mapleton, Utah

samuelaverett@gmail.com
Abstract
My experiment focuses on the growth rate of fruit trees during the transition from
winter to spring in the plains of Mapleton, UT. In this study, I have studied the
difference in growth rate of the buds, blossoms, and the leaves on the branches of apple
trees Malus pumila, pear trees Pyrus communis, a peach tree Prunus persica, and walnut
trees Juglans. My hypothesis is that different species of trees grow at different rates from
each other. . Even between species of fruit and nut trees that may have close
synapomorphy can have very different growth patterns I searched individual branches
from each of the trees for my experiment over a four week time period. To my
amazement I was to find that the leaves hadn’t produced by the end of my experiment
and that the blossoms were just coming through on some of the branches.
Elevation Influence in Growth of Wood’s Rose (Rosa woodsii) in Rock Canyon Park

Abstract
Discovering the influence of elevations on wild rose shrub growth is truly
interesting and it can reveal biodiversity in the surrounding area, but more research is
required before we can discern between the effects of elevations. Considering the
elevation differences, I hypothesized that the Wood’s rose shrubs by the Provo River
(4700 feet) would grow better than the shrubs on the mountains (Rock Canyon Park
which is 11750 feet above sea level). In these two sites, I observed Wood’s rose shrubs to
find out how their growth is dissimilar or similar in different elevations. Selected shrubs
in these areas were identified and counted, and on a weekly basis air temperature, soil
depth and moisture, height, stems, leaves, fruits were measured. As a result of my
observation, I concluded that the elevation matters in the growth of the Wood’s rose
shrubs due to precipitation level.

The Effects of High Frequency Sounds on ants: (Formicidae)
Ryan Barker, 1565 N University Ave. Apt. 183 Provo, UT. 84604 Email:
barker563@gmail.com
Abstract:
The behavior of ants collected from various locations in the Provo area was
observed in both normal circumstances, and in the presence of high frequency sounds.
The purpose of this experimentation was to test the hypothesis that ants (Formicidae)
would be repelled by the presence of high frequency sound.
The ants’ aversion to the high frequency sounds was determined by the distance
they traveled during the course of the experiment. The results of the experiments
indicated that ants are unaffected by the presence of high frequency sound as their
behavior did not change in the presence of such high frequency sounds.
Key words: Ultrasound, Formicidae, repel, Ant Repellent, ineffective
Thermal Influence in the Growth of Grass (Poa pratensis) in Provo, Utah, U.S.A

Abstract
Experiments were conducted at Glenn Park in the Canyon of Orem, Utah. The
growth behavior of grasses (Poa pratensis) is affected by thermal conditions and the
question at hand is the effect cold climates have on the growth rate of grasses found in
the area. . Plots of grass were marked and separated, and their growth rates were
measured. The difference in growth rates found between grasses in three different
locations varied by proximity to the river, tree, and center of a field. The data was also
juxtaposed against the weather/precipitation for those periods.

Survival habits and growth patterns of lichen (Xanthoparmelia) that grow specifically on
trees
Rylan R. Bateman, 1852 W 40 E Apt. 36, Provo, Utah 84604 Email:
rylanbateman3@gmail.com
Abstract
Questions arose about the effects of environmental changes on lichen. An
experiment was conducted in which samples of tree bark with lichen colonies were
collected and were randomly allocated with different watering schedules with half the
samples outside and the others kept inside at constant temperature. This experiment was
created to test the hypothesis that increased water supply and temperature lead to
increased growth in lichen Xanthoparmelia. Colonies were counted and recorded and
compared to establish whether a trend emerged and if it supported the aforementioned
hypothesis. It was determined that increases in temperature induce rapid growth on
lichen. It was also determined that an increase of water does to a certain point increase
lichen growth, but if too much water is present lichen growth would begin to slow. The
suggested explanation for this was that too much water inhibits the photosynthetic cycle
from functioning successfully.

Abstract
There are many plants growing in the Provo, Utah area that is not native to the
land here. I studied these foreign plants and their affect on their habitats in the Provo
area. Experiments were conducted in the Provo area to see what this affect is. A
comparison between a selection of three foreign plants along with their surrounds and a
control group with a similar habitat of only native plants were analyzed. After observing
the data, it was determined that the areas in which foreign plants lived that they were
highly intrusive, taking over the space of other plant areas, and had a negative affect on
the environment. The control areas that were similar to the previous environments, but
without the foreign plants living in them, had much more native plants thriving, without
having one main plant dominating the area.

Factors in the direction of the growth of Abies bifolia in Rock Canyon:

David T. Beheshti, 3105 Merrill Hall, Provo, Utah 84604, Email:
david.beheshti@yahoo.com
Abstract:
In order to find out what causes subalpine firs to grow at an angle and not straight
up, I took a series of measurements to see if the angle at which the tree grew was related
to the slope of the ground. It was my original hypothesis that the greater the slope of the
ground, the greater the angle that the tree would grow at. I also took measurements to see
if there was a relationship between the elevation of the mountain and the angle at which
the tree grew. All of these measurements were taken at Rock Canyon on the same
mountain and measuring the same tree species (Abies bifolia). My findings did not
strongly support my original hypothesis, as I found a weak correlation between the
mountain slope and the tree growth, although there was some evidence that I was correct.
While I was up there I observed, however, that the trees which grew the closest to vertical
were those with the thickest trunks. This led me to believe that it was the size of the tree
rather than the slope of the ground or the elevation that determined how the tree grew. I
confirmed this by ranking the trees in order from thickest to thinnest, which correlated
perfectly to the angle at which it grew.

Abstract:
Experiments were performed at the duck pond and NE side of BYU campus. The purpose
to test the hypothesis that bird could communicate with other species of bird. Recorded
Duck calls were played for ducks as well as Blue jay calls. Robin calls were played for
Robins and then blue jay calls. The bird’s number of responses to their native species (as
a control group) was compared to their responses to the blue jay calls to see if they were
trying to communicate with the blue jays. It was determined that birds were more likely
to communicate with their own species as expected but that they would also respond to
other species calls although this could be due to a surprised reaction rather then an effort
to communicate.

linzbird@gmail.com
Abstract
In a time where global warming is undeniably happening, the question in arisen
“Is it possible that the carbon storage and sequestration of trees could offset global
warming?” Experiments were conducted around Wyview Park in Provo, Utah. Tree
carbon sequestration and total carbon stored were studied under natural conditions near
human life. The purpose was to test the question “Can the total intake of carbon dioxide
by a tree offset my carbon footprint?” To figure this out, carbon footprints were
calculated, along with the total amount of carbon dioxide sequestered and stored by one
tree. It was determined that trees can offset the mere human existence, however, there is
no where near enough trees or potential for storage to offset the carbon dioxide emissions
of our every day lives.
Key words: Climate change, carbon sequestration, carbon footprint.

Abstract:
Observations were made near the Provo River as well as many areas in Provo,
Utah including Rock Canyon. The purpose for observations was to test the hypothesis
that trees that grow along the riverside will grow back their leaves and flowers faster than
those not along side the river. I studied mostly Quercus gambelii (gambel oak), and
Populus freemontii (Cottonwood Tree). Based on my findings I found my hypothesis to
be wrong and found more life in trees not near the river than I did by those along side it.

I have noticed that the birds chirping outside the window of my house near the foothills of Orem are not the same type
of birds I see and hear when I go to work at Sundance Resort (which is located on Mount Timpanogos), and the birds I
see when climbing, hiking and camping up the canyons of Timpanogos are also different than the birds that unite each
morning with song right outside my window. I began to wonder what role elevation played, if any, in determining
where different types of birds dwell.

Strategies and Mechanisms Used by Honey Bees to Survive Winter
Abstract:
All experiments have been performed in Provo, Utah with natural
conditions and in different situations. The nature experience purpose was to
discover any strategies or different ways bees survive the winter in preparation for
the next season. To discover this, several observations and research was done in
different places to see where bees would survive and where they would not. With
the difficulty of finding natural hives during the winter, a hive at a bee-keeping
contraption was observed. It was determined that bees under there natural hive
condition survived better that seeking warmth from any man-made facility. It was
determined that the combination of their bodies preserving energy and the cluster
formation with rotating bees about the nucleus.
Key words: Provo, cluster, nucleus temperature, and survival mechanism.
The seed preferences of birds (Aves) in Utah County

Abstract:
I conducted an experiment in my backyard located at 652 S 300 W Orem, Utah
84058. I measured and observed the seed preferences of local birds (Aves) to test the
hypothesis that when given a choice more birds prefer a seed mix over black sunflower
seeds. I purchased a dual feeder, and put black sunflower seeds in one chamber and a
seed mix in the other. To measure the bird’s preferences, I kept a log of how many birds
were sighted at 8am, 12pm, and 4pm at each seed type, over a 7 day time period. At the
end of the experiment, I took down the bird feeder to weigh the remaining seeds to see
how many pounds of each seed type were consumed by the birds over the 7 day period.
Overall, I observed 11 more birds at the seed mix than I did at the black sunflower seeds.
During the experimental period, birds consumed 1.1lbs of the seed mix compared to .4lbs
of the black sunflower seeds.
Key words: Aves, seeds, Orem, black sunflower seeds, seed mix, bird feeder.
The affects of cold water temperature on Betta splendens (Siamese fighting fish)
Kevin K. Brown, 528 N 400 E, Provo, Utah, 84606 Email: korybrown89@hotmail.com.
Submitted April 2011
Abstract. I did an experiment to see how cooler water temperature affected Betta
splendens. The hypothesis was that at a colder water temperature Betta splendens will be
less active in order to save energy to survive. The test was performed in my apartment
with two fish bowls, one acting as the experimental group and the other as the control
group. The control group was allowed to maintain the water at room temperature while
the experimental group’s water was maintained at a cooler temperature by adding ice
cubes. It was found that Betta splendens can survive at nearly 20 degrees cooler without
showing a large difference in amount of activity and eating habits. Therefore, cool water
temperatures are not dangerous to Betta splendens unless it gets to a temperature so
severe that they cannot survive.

Abstract:
Observations where conducted at the Fifth waters/ Three Forks Hot Springs in
Springville Utah. All numbers and observations where collected under natural conditions
and elements. Many people enjoy these hot springs as a weekend getaway. My purpose in
observing them was to better understand the Hot springs effect on algae growth. It was
determined that both temperature of the water and speed of water flow affected percent of
algae that could grow. Slower moving waters at about 38 degrees Celsius provided the
optimal habitat for blue-green algae to grow in the Three Forks hot springs.

Abstract
An observational study was conducted in Utah Lake and Provo Canyon to
determine the amount and diversity of bird species. The study took place on March 28th,
29th and 30th 2011. Data was taken on the number of birds as well as species across three
different areas in each of the 2 locations. Data was also taken on the elevation of the
areas of study. Of the 16 species of birds identified in the study, 14 of them were found at
Utah Lake with 317 birds sighted compared to only nine birds sighted in Provo Canyon.
This study was able to determine the most likely location for the abundance of bird
species, comparing the two areas of observation. This study took place to raise awareness
of what birds live in Utah County and where to find them.

Abiotic Factors in the Provo River, Provo, UT, U.S.A. and their Influence on
Algae Growth
Orrin H. Bunn, 1866 N 40 W Apt. 37 Provo, Utah 84604 Email: orrinbunn7@msn.com
Abstract
The growth of algae and what type of algae grows is influenced by the many
abiotic factors of their environment. Some of these factors are temperature, the pH levels
of the water, and the amount of sunlight. The factor that I wanted to test is the effect of
the acidity of the water that it grows in versus the growth of algae. I was very curious as
to how the pH level of water can increase or decrease growth. I conducted experiments
in the Provo River in Provo, Utah using ten tiles each dispersed about one quarter of a
mile apart. Observing these I tried to see algal growth and what types of algae grow in
certain levels of acidity in water. Acidity levels of the water in the locations of the tiles
were recorded and observed every other day for a period of about two weeks. After the
experiment, pH levels were to be graphed against algal growth.
Key words: algae, pH level, acidity
The influence of food sources on the locations that quail prefer.
Heather Capson, 442 N 400 E Apt.18, Provo, UT 84606
Email: chefeather@yahoo.com
Abstract:
I often noticed that there were quail in my parking lot instead of the park. This
made me wonder why this would happen, especially since the birds seemed so afraid of
people getting close to them, which would happen a lot more in a parking lot than a park.
In an article entitled Environment, well-being, and behavior, they refer to the idea that
birds will overcome a certain amount of fear to obtain a more appealing food source
(Chang GB, Liu XP, Chang TH, Chen CH, Zhao WM, Ji DJ). This made me wonder if
perhaps there was a food source in the parking lot that was not found in the park. I
conducted an experiment in which I observed quail (see figure #1) in a natural
environment (a park) and in an unnatural environment (my parking lot). The purpose
was to see what food the quail were eating, and to see if they seemed to enjoy one setting
more than the other. To determine these things I observed these two different locations
on different days at different times of the day. Unfortunately I noticed that there weren’t
always quail in these locations, despite my numerous previous exposures to them.

Abstract:
Observations were conducted at the Provo River of Provo Utah. The growth of
deciduous tree leaves was observed under the natural seasonal temperatures and rainfall.
The purpose of this observation was to test the hypothesis that the thermal influence of
spring would quickly encourage growth of tree leaves. To demonstrate this, two different
deciduous trees were picked and observed along the river. Trees were measured in
circumference, given detailed descriptions, habitat was detailed, and weather conditions
were taken down. It was found that the seasonal influence of trees was different
depending on their circumference. The larger tree showed very little change in the spring
season, while the smaller tree seemed to grow more rapidly.

Abstract:
This Experiment was conducted at the duck pond on 800 N. Provo, Utah. Ducks
were observed to see if they have a specific color preference. The purpose was to test the
hypothesis that ducks are attracted to the color green. To demonstrate this, meal worms
and bread was placed on a green colored sheet and a blue colored sheet. It was noted that
ducks did not have a color preference or food preference. Two explanations for this
would be 1) the ducks had been fed enough food and were not hungry 2) ducks are
dependent on people for their food rather than foraging for their food.

The effects of altitude on Bigtooth Maple (Acer grandidentatum) and Gamble Oak
(Quercus gambelii).
Daniel M. Cook, 166 F. Smith, Provo, Utah 84604 Email: dmc3152@yahoo.com
Abstract:
Climates depend heavily on rainfall and temperature. One of the ways that the
rainfall and temperature of a location can be altered is by altitude. Higher altitudes tend to
have lower temperatures and less rainfall while lower altitudes have warmer temperatures
and more rainfall. This characteristic of changing climates has an effect of changes in
altitude is characterized by the Bigtooth Maple (Acer grandidentatum) and the Gamble
Oak (Quercus gambelii). By measuring the sizes of the trees and making observations of
their growing conditions, the effects of altitude become apparent. At a high altitude these
two trees were short and both grew in clusters. They were disorganized and were
prominent in the biodiversity. However, at a lower altitude these two trees started to show
some differences. The Bigtooth Maple grew more in isolation and didn’t try to compete
with other trees. The Gamble Oak still grew in the same form as before but each tree
grew farther apart and much larger than at the higher altitude. Knowing these
characteristics for different altitudes is useful in deciding which trees would be best to
grow in a garden at different altitudes.

Abstract:
Observations and experiments were conducted throughout Rock Canyon in Provo, Utah at various elevations.
Throughout the canyon there are numerous species of vegetation. The purpose was to test the hypothesis that plant life
must adapt and evolve in order to survive at different geographic locations, namely at the base and peaks of Rock
Canyon. I chose two different locations to gather data: Bridal Veil Falls & Squaw Peak. At each of these locations, I
observed the biodiversity around me and tried to uncover what caused certain trees to grow at different altitudes. I
selected 10 red osier shrubs (Cornus stolonifera) at Bridal Veil Falls, and 10 Washington Hawthornes (Crataegus
phaenopyrum) at the top of Squaw Peak to gather data on height and circumference of tree trunks. Using this data, I
could then partly determine what enabled each species of tree to grow at each particular location. After returning to my
lab to analyze the data, it was determined that my hypothesis was indeed correct in stating that plant life had to of
adapted to varying degrees of elevation.

Email: Jorgen.davidson@gmail.com
Abstract
I studied the regrowth of leaves in all species of trees, including
Hippocastanoidaea Acer and Saliceae Populus present in different locations near Provo
Utah. Different areas that were characterized by abiotic factors including access to
sunlight and water were monitored to see in which areas the springtime regrowth of
leaves would occur soonest. Because the experiment had to be completed near the
beginning of April 2011 during the monitoring period there was no regrowth of any kind
on any trees that were monitored.

Zonation of the Gambel Oak (Quercus gambelii) and the Greene Mountain Ash (Sorbus
scopulina)
Corbin M. Dean, 380 N 1020 E Apt. 301, Provo, Utah 84606 Email: corbinmd@gmail.com
Absract. Experiments were conducted on Y Mountain of Provo, Utah. New bark growth
was measured under natural conditions on the mountain, with a standard U.S. measuring
tape. The purpose was to test the hypothesis that as altitude increases the amount of new
bark growth of the Greene Mountain Ash (Sorbus scopulina) would decrease, due to the
drop in temperature associated with higher elevation. In order to test this, measurements
were taken of the new bark growth of individual Greene-mountain ash branches. The
measurements were taken at chest level branches for the North, South, East and West sides
of the tree. The measurements were taken subsequently with an approximately 50-foot rise
in elevation in between measurements. It was determined that there was no correlation
between the amount of new bark growth and the rise in elevation. However I discovered a
case of competition and altitudal zonation between the Gambel Oak (Quercus gambelii)
and the Greene Mountain Ash (Sorbus scopulina). It was noted that at the elevation of
approximately 5,500 feet, the Greene mountain ash capitulated with the exception of one
super subject and the Gambel Oak became the dominant species above this altitude
boundary. This spontaneously discovered phenomenon of zonation may be a foundation for
future studies for further understanding of this ecosystem.

doug_destro@yahoo.com.br
Abstract
Among the most common subjects taught in schools is an important process that
plants go through during their entire lives called photosynthesis. It is through this process
that plants can produce their own food and continue to live and perpetuate their species.
However, plants are completely dependent upon a source of energy in order to
photosynthesize, light. The nature of light has been the subject of controversial debates
among great minds, resulting in the proposal of different theories since mankind began to
observe and measure nature. Nowadays, with the aid of key instruments, scientists are
able to understand more about light and how it relates to photosynthesis. In this study,
four plants of the same species (Brassica oleracea) were placed under different sources
of light. I tried to maintain all other possible variables as constant as possible for all four
plants, such as room temperature, water and time of exposure to light. It was determined
that plants can grow well under artificial light as long as proper attention is given to each
plant’s specific needs for intensity and type of light.

Adverse Temperature Effects on
Selaginellaceae Selaginell Seauv in
Provo River Canyon

Abstract
Selaginellaceae is an ancient group of ferns. The family is comprised of some 750
species and is found mostly in tropical rain forests. It is also found in mountainous, high
elevation regions, where the present observations will take place. The report seeks to
prove a hypothesis that a decrease in temperature will adversely affect growth of
selaginellaceae selaginell beauv. With decreasing temperatures, the author predicts a
decrease in dimensional size. Nine samples of selaginellaceae selaginell beauv are
monitored during a predicted time of temperature decrease. The sample’s dimensional
size is correlated with temperature to determine if the hypothesis is correct. The report,
you will find, is inconclusive in proving the hypotheses correct. Reasons are given for the
possible source of the experiment’s inability to prove the hypothesis, and a new
hypothesis is given.

Abstract:
Experiments were conducted in Provo, Utah, Edgemont area, at the location of 40
deg., 16 hrs. 26.44 sec N. /111 deg., 39 hrs. 21.14 sec W., elevation 4725 ft. observing
and analyzing the potential cone opening stage of the Picea sitchensis, commonly
known as the Sitka spruce. This study involves a narrowing of three differing cone
opening mechanisms which all use heat as the common denominator. Taking into
consideration, I used heat as the trigger in opening a cone prematurely. The study was
conducted with three different heat sources.1- ultraviolet range of 10 nm through 100 nm
wavelength range; 2- convective heat range of 100nm through 10 to the third power wave
length range nm; 3- microwave range of 1mm through 10 m. My study illustrates the
need for heat or energy from the Sun to help promote the germination process of conifer
trees and forests which is critical for energy flow and nutrients cycle.

The effect of the growth of herbs when grown together
Anna Dollins, 1505 N. Canyon Rd. Apt. 42, Provo, UT 84604; Email:
annae.dollins@gmail.com
Abstract:
The experiment was conducted in pots, filled with soil, outside of my apartment in a
garden area. It is common to find several different herbs being grown together. However,
the growth of an herb is affected by what other herbs it is being grown with. To
determine what herbs grown best together I conducted some research by reading in herb
gardening books. I purchased the herbs locally as already flowered plans, as opposed to
seeds due to the amount of time it takes for a seed to completely germinate. I planted the
test herb, rosemary (Rosmarinus officinalis), twice, each one in a separate pot planted
with different herbs, oregano (Origanum vulgare) and sage (Salvia officinalis), in order to
track the affects of the herbs on the rosemary's growth. The premise of the experiment
was that rosemary would grow better with sage than oregano due to their similar needs in
light and watering, as opposed to oregano. The both rosemary plants grew one inch
higher from the time they were bought and planted. I deducted that both herbs helped the
rosemary to grow better, however I failed to plant a third rosemary plant as a control,
which would have helped me to determine the true effects of the herb growth.
Key Words: Rosmarinus officianlis, Origanum vulgare, Salvia officinalis, growth.
Diets of mule deer (Odocoileus hemionus) in different weather conditions in an apple

Abstract:
The diets of mule deer (Odocoileus hemionus) change according to local climate
variation. To find out what mule deer in Provo, Utah eat in different weather conditions,
I conducted experiments in an apple orchard off of Center Street in Provo, Utah. I took
food samples after field observations in varying weather conditions including snow,
overcast, and sunny. Their diet in the snow consisted mostly of grass and tree bark, but
when it was sunny, they favored grass over tree bark. Overcast weather yielded no
further analysis because deer were not present to observe. The food supply of mule deer
is limited by the availability of the plants they eat, which availability is influenced by the
change in weather and temperature.

Affect of Altitude and Temperature on the bud growth of Gambel Oak (Quercus gambelii
Nutt.)
Hailey Edgington, 2216 Hinckley Hall, Provo, UT 84604 Email:
haileyedgington12@gamil.com
Abstract
Gambel oak is a plentiful shrub and in the past few months has started to produce
buds in Utah. An experiment to test whether altitude and temperature have an affect on
the size and quantity of bud growth was conducted. The hypothesis is that indeed
temperature and altitude do affect the size and quantity of gambel oak buds. Bud size
and quantity were measured on three different days at three different altitudes in the
Provo Canyon. The results proved that the hypothesis stated was correct; altitude and
temperature did have an affect on the size of gambel oak buds and the quantity of buds on
the shrub.

dpe22.yamanu@gmail.com
Abstract:
During my time in Andalucia, Spain, I noticed that great numbers of Spanish Barn
Swallows (Hirundo rustica) would gather to “perform” as it were, over an open
swimming pool. I observed the birds for five days (Mon-Fri), at 7:00-8:00 AM, 12:001:00 PM, and finally 5:00-6:00 PM. I hypothesized that the birds would be most active
when the weather was warmer, and that they were gathered to rehydrate themselves. I
went to the pool everyday where the largest population of barn swallows was present and
observed their behavior as it was affected by temperature (weather conditions), time of
day, and number of barn swallows present. Most barn swallows were present in mid-day
(when the weather had warmed up), than in the early and evening hours (when the air
was colder). The number of barn swallows present had a surprisingly large effect on the
social behaviour of the birds, which like showing off, according to my data. Human
presence surprisingly had no effect on the activity of the birds above the pool. The
weather was stormy on Thursday and Friday, and there was no activity from the barn
swallows. The great number of barn swallows present was due to the fact that Andalucia
is the jumping of point for European birds migrating south to North Africa.

Comparing the characteristics of flora that grow in St George, UT with those that
grow in Provo, UT: two different biomes.

Email: catieellis13@aol.com
Abstract:
I compared characteristics of plants and trees from St. George, UT to those found
in Provo, UT. I made observations of the different flora that I took pictures of and
compared characteristics like, flowering color, height, and branching patterns. I found
that, with the flora that I used, those found in Provo were taller than those found in St.
George and they also produced seeds that where usually brown. I also found that despite
the great difference in climate in Provo and St. George, there are still plants that can grow
in both. That plant that I found was Forsythia suspensa. My experience doesn’t really
explain anything new, but it was interesting to confirm the things that I have been taught
in the class, and to question things that I wouldn’t have otherwise.

Abstract
The appearance of bugs and Insecta are affected by climate, but research is
required to find what species are affected by climate change. Experiments were
conducted at an empty plot of land in Provo, Utah, near the Wasatch Mountains (figure
1), with hopes of discovering species’ variations and population density found beneath
rocks as the weather’s temperature increases. This was done in order to determine which
insects can withstand the cold weather and to test the hypothesis that insects and bugs in
general, move closer to the surface as weather heats up. At different sites rocks were
lifted, present species were indentified and counted, and finally temperature was
recorded. This process was repeated 4 times, each occurring at approximately three
o’clock pm, over the course of 4 weeks as the weather and season changed. It was
determined that weather does indeed affect bugs’ desire to reside under rocks.

Abstract
Life cannot exist without water. It is an essential building block for all life forms.
I performed an experiment where I measured the quantity and variety of insect life in the
Utah Valley. The hypothesis was that the relation between proximity to water and insect
life would be indirectly related, that is, as distance increases then insect life decreases. I
chose three locations based on proximity to the Provo River to place bug traps in order to
test my hypothesis. The traps were left in place for a week and then retrieved. I found that
the opposite of my hypothesis proved to be the case. More bugs and variety of insects
were found in the traps farther away from the Provo River than in the ones nearest to it.
Variables such as heavy rain and elevation during the experiment affected the results of
the experiment
Light Attraction of Aquatic Insects

michellef44@gmail.com
Abstract
I observed the attraction of aquatic insects to light in a small pond located at the
Bicentennial Wetlands Park in Provo, UT. The purpose of this observational experiment
was to test the hypothesis that similar to their dry land counterparts, aquatic insects are
also attracted to light. While previous research has shown and it is easily observable that
many insects are attracted to light the purpose of this research was to expand this
knowledge and observe if aquatic insects exhibited the same behavior and attraction as
their dry land counterparts. Six light traps were constructed during March 2011. These
were placed in the pond overnight and then removed from the test site and the total
number of insects captured was recorded. It was found that the results of the experiment
did not support the hypothesis that aquatic insects were attracted to light as only one
aquatic insect was captured throughout the duration of the experiment.

Abstract
This experiment has been performed at three predetermined locations here in Utah
County. One plot up on the mountainside behind the temple, one plot on Brigham Young
University campus, and another plot down beside Utah Lake. My hypothesis is that there
will be more worms in the soil the closer we get to Utah Lake. To measure this I poured a
solution into the soil at the predetermined locations, I then counted how many worms
came up out of the ground. My data showed that there was the same population of worms
at the lakeside location and the BYU location compared to the mountainside location.
The location in the middle, which was on Brigham Young University campus, was an
unexpected result because I expected it to be a median between the lakeside and the
mountainside location..

Abstract
Experiments were performed in Provo Canyon, Provo, Utah. Ant population was
observed and researched, influenced by natural factors and conditions. The mystery of
what determines the location of ant colonies is discussed and sought after. The hypothesis
was that ants are attracted to and settle down near tree patches, which would better
provide for their necessities. Research was done and performed on 40 test locations,
categorized into 4 separate distances from tree patches. The number and results were than
recorded and organized into results that lead to the verification of the hypothesis. It is
indeed noted that ant (and insect population as a whole), is more dense and heavily
populated near and closer to trees, than it is farther away.

The Duration of the Healing Process of Severed Branches in the Red Oak (Quercus
rubra) and Burning Bush (Euonymus alatus)
Robert C. Francis, 2219 Budge Hall, Provo, Utah 84604 Email:
bobert.francis@gmail.com, submitted April 2011
Abstract:
When most plants are wounded, they eventually form a callus around the wound
site. This process generally takes a year or more. The purpose of this experiment was to
observe the short term effects, over a period of three weeks, of severing branches from
two varieties of woody plants, bushes of the variety Euonymus alatus or Burning Bush
and trees of the variety Quercus rubra, or Red Oak. Over the course of this study the tips
of ten branches were cut from several trees and bushes in the greater Provo, Utah area.
The branches with severed tips were demarcated by taping the branch below the wound.
These branches were monitored over a period of three weeks. No changes to the overall
plant health were observed, but tissue death occurred near the wound site. The short term
effects were similar for both species, but trees responded more slowly. Following these
observations the wound site was cut into at .5 millimeter increments in order to observe
interior effects. Again, the results were consistent in both species, with amount of tissue
death correlating positively with breadth of the branch.

The Role of Salt in Decomposition
Between Two Leaves Species in BYU
Campus, Provo, Utah
Andres M. Galan, 1278 S 1040 E, Orem, UT 84097 Email: andresmgalan88@gmail.com
Abstract
Experiments were conduced in BYU campus with two leave species. Sample of leaves
from each tree species was taken to the MARB building to be measured and analyzed.
The purpose of this experiment was to test whether salty water speeds the rate of
decomposition of leaves or not. To demonstrate this, a sample from each leave species
was put in containers with water and different amount of salt. Two main variables were
taken into consideration: the weight of the leaves and PH of the salty substance. They
were measured at the beginning and at the end of the experiment, and the change was
analyzed. It was noticed that the PH does not have a big change in the substance, but the
appearance and weigh of the leaves in the container with the biggest amount of salt had
lower decomposition rate.

Abstract:
Observations were made in the Rocky Mountains and in the valley close to Provo,
Utah. Different tree species were observed to find what species can grow, or grow best,
in which altitude. Species in each altitude level were identified and different
characteristics of each tree were compared. The intention of these observations and
examinations were to discover what influence the altitude had on the trees in that area
and which trees could not grow at certain altitudes. The characteristics that will be
observed are the size of the population of the tree species, and the altitude the habitat that
the tree is in. I hope to discover what characteristics are either caused by or result in the
Altitude.

The difference of Moth (Heterocera) reaction to ultra violet and visible light in Provo,
Utah.

Shane.e.gallagher@gmail.com
Abstract
I studied how moths (Heterocera Lepidoptera) react to different wavelength of
light by observing the moths in Provo, Utah. The attraction to light of moths can be
observed around any streetlight. “[Moths] have evolved eye types that are extremely
sensitive to light in order to cope with low light intensities during the night” (Nordtug
1990). However, the reason for this attraction is unknown. Through my research I
learned that moths are more attracted to ultraviolet light than other wavelengths. Over
the span of one week two light traps identical in construction were placed outside. One
trap will use ultraviolet light and the other will use white light, or light from the visible
spectrum. Moths were exposed to different wavelengths and the number of moths caught
in each light trap were counted and compared. Due to weather conditions, no moths were
caught during the experiment however, I learned that in general ultraviolet light catches
more insects.

Abstract:
Experiments were conducted in Spanish Fork, Utah. The decomposition of four sets
of 4 half sliced avocados (Persea americana) were observed. Two sets were placed in
vacuum sealed bags,one outdoor , the other indoor. Two additional sets were placed out
in the open without any sealants, one indoor the other outdoor. Temperature
measurements and photos were taken every day to record the process. It was determined
that being cut off from oxygen did release methane gases therefore slowing down the
decomposition process.It was also determined that those samples placed in warmer
environments decomposed faster.

The Difference in the Population of Aquatic Insects Between Stagnant and Active Water
at the Provo River: Provo, Utah, U.S.A
Sutten L. Garnett, 2002 Stover Hall, Provo, UT 84604 Email:
s_utteng_arnett@hotmail.com
Abstract
This experiment was conducted at the Provo River of Provo, Utah. Specimens
were gathered from two separate bodies of water: active and stagnant water. Insects were
gathered from each aquatic area in order to conduct an experiment to test whether there is
a greater population of insects in or around actively running water or still standing water.
Notes were taken and specimen gathered for the purpose of the experiment to conclude
which aquatic area held the largest population. The actively running water contained a
larger variety of insects, but a lower population. The still standing water held a lower
variety of insects, and held a larger population. This is due to the risk of living around a
constantly moving body of water or a still standing aquatic area where water is easier to
obtain. It was found that the stagnant water held the largest population of insects.

Abstract:My experiments took place in three different locations: Provo Canyon
(40° 19′ 45″ N, 111° 37′ 33″ W), Provo metropolitan area (476 N. Seven Peaks Blvd.
Provo, Utah 84606), and at the base of Y Mountain (40° 15′ 11″ N, 111° 36′ 38″ W), all
of which are of Provo, Utah. Bird diet was closely observed in the locations specified,
under utterly natural occurring temperate conditions. The birds were presented sunflower
seeds to eat of three different flavors: barbeque, dill pickle, and seasoned. The three
flavors of seeds were of the same brand “Spitz.” The purpose of the experiment which I
ran was to test my hypothesis that temperature does not affect the flavor of sunflower
seed eaten by the birds (Aves), but temperature merely affects the amount of sunflower
seeds which the birds eat. To exhibit this I placed the flavored seeds on the ground in the
three locations previously specified, and took into account the amount of each group of
flavored sunflower seeds eaten and the temperature of the time which I was there. After
the specified time lapse period, the flavored sunflower seeds were collected and weighed
on an electric scale. Also, the temperature of the day was taken with a thermometer. It
was clear that the temperature of the day affected not the flavor of the sunflower chosen
to be eaten by the birds, but the amount which was eaten was measurable less. This was
determined by the comparison of starting verse finishing weight of the sunflower seeds
presented. I could determine that the temperature of the day had a notable affect on the
amount of sunflower seeds eaten. The location, whether rural or urban, notably did not
play a prominent role in seed consumption. Key words: Aves, Y Mountain, Provo

Abstract: I hiked the Y, noting and taking pictures of the different plant life as I
traversed the steep incline up the Y Trail. The 1000 ft. increase in elevation provided
somewhat of a visible difference in plant life, with smaller plants and shrubs near the
bottom, to clusters of somewhat larger plants in the middle, to the pine up near the top of
the mountain. Many of the trees lacked leaves, making it somewhat difficult to identify
them, but I’m pretty confident that I’ve identified them correctly. This experience should
provide a basic understanding and knowledge of which plants exist at certain elevations.

Abstract
I studied earthworms (Lumbricus terrestris) and their response to rain. During
and following rainstorms, worms can be spotted in abundance on the sidewalk when it is
overcast or dark rather than in the soil where they are normally found. I formulated the
hypothesis that the worms left the soil because they would drown from the excess of
water in their habitat, and did so in darker conditions because of the possibility of drying
out completely. To test this theory, I simulated a rainstorm. Using worms I had collected,
I tested whether they do in fact come out due to the water from rain or other sources, and
whether or not it is actually possible for worms to drown. I found that I was unable to
fully determine why the worms moved from the soil as they do, but I did determine that it
was not due to drowning. I also determined that the worms only come out in the dark to
avoid drying up in the sun, and they are unable to be in the sun for long without dying.
Temperature and pH soil as factors in determining changes
in leaf chlorosis in Mahonia aquifolium
Nuria Giménez-Guijosa, 631 South 850 West, Springville, Utah 84663
Email: gimeneznuri@hotmail.com
Abstract
In the physical world in which we live, there are many factors that affect plant
and, consequently, leaf growth. Some of these factors include the temperature and pH of
the soil in which the plant or tree is found. Such factors affect particularly the bush
Mahonia aquifolium, commonly known as the Concord grape bush. In this experiment, I
measured these factors for particular group of bushes and came to the conclusion that
intermediate temperature and acidic pH are favorable to leaf growth as they do not
promote chlorosis, or leaf deterioration.
The Effect of Sunlight and Climate on Coniferous Tree Growth vs. Deciduous Tree
Growth

green.tanner@gmail.com
Abstract:
Trees rely greatly on the sun as well as other factors for proper growth. The
purpose of this experiment was to see whether or not deciduous trees rely more on the
sun in Provo’s climate than conifers do. To achieve this I measured tree circumferences
of four sets of five trees, two sets located in sun rich environments, and the other two sets
in poor sunlight environments. I calculated the averages of the sets of five trees to find
the differences between the total average circumferences of each species. The
experiments were performed at various locations throughout the campus of Brigham
Young University. I found that the difference of the averages of the deciduous trees was
significantly higher than that of the conifers, and concluded from my results that
deciduous trees do in fact rely more heavily on the sun in this climate than do coniferous
trees.

The influence of continuous sun on the growth of grass (Poaceae: Poa)
Matt S. Griffin, 215 E. Richards Hall, Provo, Utah 84604 Email: msg29@byu.net
Abstract:
Measurements of grass were taken on BYU campus four receiving sunlight all
day, two receiving sunlight in the morning, and two more receiving sunlight in the
afternoon. Grass (Poacaea: Poa) is quite capable of becoming dormant and tolerating the
cold for its season, and just goes off growing where it left off. Grass growth was observed
during early spring to test the hypothesis that grass grows at different rates depending on
how much sunlight is present throughout the day specific to that spot. To test this
hypothesis two trees that I walk by many times a day so that I could observe the amount
of sunlight each grassy area the measurements are taken from all measurements are taken
near two trees to control the amount of sun light each area gets. Each measurement is
taken at the same time of day 24 hours apart and first measurement was taken after the
sun was over the mountains illuminating the valley.
Influence of elevation, sunlight and temperature on Pinus ponderosa and Quercus
gambelii
Daxson Hale, 865 N 160 W Apt 106, Provo, UT 84604 Email: daxsonhale@gmail.com
Abstract:
Observations and measurements were taken of several species of plant life on the
west face of Maple Mountain in the Wasatch Range (just southeast of Provo, UT). The
study concentrated on two types of trees, namely the Ponderosa pine (Pinus ponderosa,
subspecies scopulorum) and the Gambel oak (Quercus gambelii), more commonly known
as scrub oak. It was observed that, though these two trees grew very close to each other,
were rarely found mixed due to differences in elevation and placement on the mountain.
The hypothesis was that sunlight and temperature was the major factor in the notable
difference in the areas of growth of the plants. Tests confirmed this hypothesis and
offered other explanations as well.
Key words: Wasatch, Ponderosa pine, scopulorum, Gambel oak, scrub oak, sunlight.
Effects of Elevation on Trees both Deciduous and Evergreen Living in the Utah
Valley
Camille Hansen, 1222 Stover Hall, Provo, Utah 84604, Email: Camelcam853@aol.com
Abstract
The types of deciduous and evergreen trees common in the Utah Valley are vastly
different from the types of trees in my hometown (Sandy, Oregon) located in Northwest
Oregon. As a huge factor between the two regions is elevation, an interest was sparked in
my head as to how elevation effects tree growth in certain regions and why. An
observational study was conducted in Rock Canyon (in Provo, Utah) to determine the
variability in tree species at different elevations. My intent in studying the effects of trees
in the Rock Canyon is to understand which trees grow where, and why certain trees do
well at a higher elevation. My hypothesis was that evergreen trees tend to grow better at
higher elevations than deciduous trees and that, vice versa; deciduous trees tend to grow
better at lower elevations than evergreens. To test this hypothesis, I conducted an
observational study on the tree population around Rock Canyon by consulting a GPS for
coordinates and elevation at various points on the trail at Rock Canyon and, in doing so, I
observed the variability among trees within the general region of those coordinances.
From here it was discovered that evergreen trees were more common the higher I hiked
on Rock Canyon (the higher the elevation).

ABSTRACT
When the north winds blow and spread the winter’s bitter cold over the face of the
earth, some spiders die off while others find a warm place to hibernate and survive the
winter. In this study, I went to various locations in the Provo and Orem area and found
spiders hibernating in garden areas, woodpiles, window sills, garages, sheds, cellars, in
the woods, under the dead leaf remains in the woods, underneath tree bark, under rocks
and in the soil. I identified specimens and recorded their characteristics - like body size,
color, eye arrangements, legs, abdomen, carapace and chelicerae. I also kept a record
about each spiders’ habitat; what their webbing looked like and what their behavior was.

The effect of elevation on the size/growth of a variety of common plants in Rock Canyon,
Utah
Sarah Harrison, 1910 Gates Hall, Provo Utah 84604 Email: sfunkyirish@gmail.com
Abstract:
I took measurements of the plant sizes of three different species in three different
locations with different elevations in Rock Canyon, Utah. My hypothesis was that,
because of stress caused by abiotic factors, every species at higher elevations would be
smaller than those of the same species at lower elevations. This hypothesis was false.
One of the species did decrease in size and did not even appear at the highest elevation
point, but the others did not follow any visible trend although their size did change. (see

The influence of climate temperature on the physical characteristics of earthworms
(Phylum Annelida)
A study conducted by Talmadge Haslam, 1119 Merrill Hall BYU, Provo, UT. Email:
TalHaslam@gmail.com
Abstract:
Observational experiments were conducted in Provo, Utah in times of varying
Climate temperature. Earthworms were dug up and sampled in their natural habitat in
order to formulate unique hypotheses relating to the behavior of these creatures. The
purpose of this experiment was to help understand the behavior of earthworms as it
relates to the cultivation of crops by modern humans. The understanding of these
creatures is vital to our success in providing and utilizing a well rounded food web in
which earthworms play an important role. By observing these creatures in their natural
habitat, we can come to important conclusions on how to understand their role further. To
quickly summarize the results of the experiment, the worms observed in multiple
environments shared general characteristics. Cold climates during the Utah Valley’s
winter cause worms to burrow deep within the soil during times of cold, seeking
protection from the elements. However, the cold weather causes the worms to grow

worms in warmer climates.

Abstract
The mule deer is commonly seen roaming the streets of Provo, especially in
winter. This experiment was conducted among three points of interest in Provo, Utah in
order to determine how the cold temperatures of winter can affect behaviors of the
common mule deer (Odocoileus hemionus). The research was performed to the
hypothesis that lower, colder temperatures would increase populations of deer in urban
areas. Temperatures and numbers of deer were recorded at each of the three observation
points, Rock Canyon Park, the Provo Temple, and the Marriott Center on the Brigham
Young University campus. The deer were observed under natural conditions. After
documenting the data, trends were observed between the temperatures and the amount of
deer counted. Evaluating the results confirmed the hypothesis that the deer would
generally travel into the city when temperatures were colder. The lower the temperature
in the morning was, the more deer could be found searching the areas for food.

Abstract
Coniferous trees, specifically the White Fir of the Rocky Mountains (Abies
Concolor), maintain their needlelike foliage throughout the year. These needles, albeit a
small difference, vary in size on each individual tree. I gathered samples from White Fir
from a total of nine trees from three locations, three trees in each location. Samplings
included sprigs of needles from each tree, tree trunk circumference, altitude in which the
trees were found, needle size according to tree, and needle size averages from each
individual sprig. I compared the averages of needle size against the elevation of their
location, and then I compared the needle averages according to each individual sprig of
needles from each tree. Results suggested that needle size is not directly associated with
circumference, is possibly associated with elevation and has definite correlation to the
sprig from which they were sampled. This unexpected variable was found in the middle
of gathering length data in the needles; the needle size was relatively consistent in
relation to the sprig that it was pulled from, but not due to the tree’s circumference or
elevation.

Movement trends of Odocoileus hemionus on Y Mountain, Provo, Utah
Cameron K. Hill, 1080 E. 450 N. #19, Provo, Utah 84606 Email: ckhill89@gmail.com
Abstract
Mule Deer (Odocoileus hemionus) can often be seen by hikers or animal viewers
on the face of Y Mountain. In this study, observations were made and recorded of the
movement trends of the Mule Deer on Y Mountain. These observations were made while
hiking the Y during various times of day, weather conditions, and days of the week over
the course of a 2 month period. During over 8 Y hikes and 6 additional observations from
the trailhead and surrounded paths, concrete data was collected. Although deer were not
sighted every time of day or weather condition, I hypothesize that the deer on Y mountain
are to be found lower on the mountain, closer to homes, during dark hours, are not highly
concerned with hikers on Y trail, and appear to bed down during more harsh weather
conditions.

Color Change and Abscission in Coniferous and Deciduous Trees
Kristi Hill, 351 E Center St. #305, Provo, Utah 84606 Email: kristilynnhill@gmail.com
Submitted April 2011.
Abstract. I performed an observational study of over 15 trees around the region of Provo,
Utah. The study focused on why leaves change color, looking at other reasons including
the evolution of trees to adapt to insect infestations. The observational study also looked
at abscission of leaves and when it occurs for certain types of trees and why the time of
year varied for the coniferous and deciduous trees. Drawing on personal past experience,
I compared my tree experiences in Provo, to other experiences in Upstate New York and
Southeastern Brazil.

Water’s influence on the amount of time it takes for deciduous trees to come out of
dormancy
Katy E. Hindman, 1874N 80W Provo UT, 84604, katehindman@gmail.com
Abstract:
In my research I studied the dormancy of deciduous trees. In the spring, trees do
not all come out of hibernation at the exact same time and I looked for a specific reason
as to why trees come out of dormancy at different times. I conducted my experiment in
Provo, Utah. In my experiment, I determined whether a tree’s proximity to a large body
of water would make it come out of dormancy faster. I chose two trees, one that was
close to the water and one that was far away to do my experiments on. The trees outer
appearance was observed by looking for coloring in the bark, leaves, and leaf buds. The
inside of the tree was also looked at for signs of sap flowing through the tree. It was
found that the tree farther from the water was actually starting to come out of dormancy
faster than the tree closer to the water. I determined that this could mean that either being
far away from the water will make a tree come out of dormancy faster or that water has
nothing to do with the speed that it takes a tree to awaken.

Date: Winter 2011
Abstract
In Febrary 2011, there was a week of unusually warm weather in which
Liriodendron tulipifera, Celtis occidentalis, and Magnolia ‘Jane’ began to show signs of
blooming. This study examines whether or not the beginnings of buds during this week
would eventually cause the tree to bloom earlier than normal. Starting the day after the
warm weather had passed I began to observe the changes in the buds over the course of a
month and a half using a camera and notebook. I found that the trees did not bloom any
earlier than they normally do and that a short period of warm weather in late winter does
not have much of an effect on the blooming of trees.

The Effects of Air and Water Temperature upon the Foraging
Behaviors of Cinclus mexicanus (American Dippers) in Bridal
Veil Falls and Nunn Park, Orem UT.

April 2011
Abstract:
The American Dipper is known to prefer cold, fast mountain streams, however
there is a lack of data on the Dipper’s tolerances for environmental temperature, and how
it affects their stream side behaviors. This paper relates the findings of observations
conducted at Bridal Veil Falls in March 2011 to determine what correlations, if any, there
are between water and air temperatures and the Dipper’s foraging activities. It is
determined that water temperature has greater influence on Dipper activity than air
temperature. It is also determined that current data may be insufficient, that greater
natural variations in temperature would be needed to determine tolerances, and that a year
round study should produce better results.

Abstract
The population of mayflies (Ephemeroptera), stoneflies (Plecoptera), and
caddisflies (Tricoptera) is greatly influenced by water quality, whereas the population of
midges (Chironomidae) is not. Because of this the relative populations between EPT and
Chironomidae gives us a quick and accurate representation of the health of a given
water’s ecosystem. Experiments were conducted in three separate locations on the
Middle section and three locations on the Lower section of the Provo River (the Middle
Provo is tailwaters of the Jordanelle Dam to Deer Creek Reservoir; the Lower Provo is
the tailwaters from Deer Creek Reservoir to Utah Lake). The subjects were collected
primarily by using the kick-sampling method and immediately identified and recorded.
The EPT index was then calculated by dividing the total number of insects from the
orders EPT, and divide that by the total number of EPT insects plus insects of the order
Chironomidae (EPT / EPT + Chironomidae). This was done twice a week for three
consecutive weeks. What I found was that the Lower Provo River has a smaller EPT
index, which falls at a steeper rate while travelling downstream that does the Middle
Provo River.

Abstract
Benthic macroinvertebrates are often taken as important indicators of overall
stream health. One of the most essential aspects of steam health being dissolved oxygen;
this report looks at several species of macroinvertebrates and the levels of dissolved
oxygen they require. I took samples of specimens from a number of sites of varying
levels of dissolved oxygen along the Provo River. These samples were small, ranging
from 20-35, and not meant to be proportionally representative of the macroinvertebrates
present but rather to establish the presence of certain types in each site and to measure
what species would be present at which site. Altogether 128 specimens were taken from 5
different sites. These sites ranged in dissolved oxygen from 3 ppm to 7 ppm. In the
lowest level of dissolved oxygen only Chironomidae larvae were found but in higher
levels of oxygen various nymphs of the suborder Zygoptera could be found as well as the
species Asellus aquaticus. Of the specimens collected the Chironomidae larvae seemed to
have the greatest range of tolerance in dissolved oxygen levels.

Influence of water depth and clarity and type of bait used on the number of
Oncorhynchus mykiss, Salmo tratt, and Prosopium williamsoni fish caught in the Provo
River
Katie Jagoda, 2099 N 120 W #254, Provo, UT 84604 Email: katiejagoda@hotmail.com
Abstract
I chose to figure out the best methods of fishing in the Provo River in regards to
the most effective bait out of lures, power bait, and night crawlers, and what depth and
clarity of water is the best for fishing success. For my experiment, I went up to the Provo
River on three separate days, devoting each day to a different kind of bait and trying to
fish in shallow, deep, and murky water to see where and with what bait I would find the
most success, hypothesizing that I would me most successful using the power bait in
deeper water. After doing my hours of fishing and recording my results, I found that I
was able to catch the most fish using the night crawlers and fishing in shallower waters.
These results are most likely because of a fish’s desire to have live bait, food that they
recognize, and also, this is the season for fish to be spawning, so they are in shallower
areas of the river to lay their eggs and receive the oxygen they need. My founded
methods of success in fishing agreed with those of other experts and fisherman.

Abstract:
Avalanches are one of the most common natural occurrences. They commonly
occur in mountainous terrain and take place when large amounts of snow or ice slide
down the mountainside. They can be one of the most serious hazards to human and
natural property with their ability to carry large amounts of snow over long distances. An
experiment will be conducted in the Provo Canyon to determine whether avalanche
disturbances have a positive or negative effect upon the diversity of plants within the
area. The number of different types of plants will be observed in an avalanche
disturbance zone and in a non-disturbed forest. This experiment should demonstrate
avalanche disturbance creates greater plant diversity in a mountainous area.

Abstract: Mountain Cottontails are abundant near my home in Billings, Montana. Using
many different foods I heard rabbits ate, and the staple of food for Bugs Bunny (carrots),
I predicted that rabbits would eat not only carrots, but also some of these other foods my
friends had mentioned to me. I had two different sites where food was placed. I
performed the experiment for five days. To my surprise, I found that rabbits did eat the
carrots as expected, but a few of the foods my friends said they would enjoy were not
even touched. The second most consumed food was apples, followed by bananas and
celery. Also, the rabbits avoided potatoes and oranges completely.

Do Birds Sing Louder in Urban Areas in comparison to Rural Areas
Emily Johnson
Abstract:
Birds chirp for a variety of reasons and in many different ways. They will sing
pleasant songs in the morning, or might chirp to communicate with other birds.
Experiments were conducted on the average decibel at which most birds chirp in different
environments. These experiments took place is a variety of places ranging from urban, to
rural, and some in between. It is my hypothesis that birds living in major cities will chirp
louder than those living in natural habitats, perhaps for the reason that they just want to
be heard. To conduct this experiment, I had 2 different sound meters that I would take to
the quietest and loudest parts of that city/area to get an average for the area. Then I would
wait for birds to chirp and observe how much the decibels spiked. I wrote down a range
at which the meters read when the birds were chirping, getting an average for the birds’
chirps. This didn’t tell me at which decibels birds chirped, but told me the volume of the
city and the bird noises together, giving me an idea of how much the chirp varied from
the average city noise, if at all.

Affect of Precipitation on Leaf Decay for Quercus gambelii leaf litters in Rock Canyon
Park, Provo, Utah
Riley J. Johnson, 2111 May Hall, Provo, Utah 84604 Email:
rileyjohnson.cool@gmail.com
Abstract
Utah has had less precipitation than it normally does during the winter. Due to
this fact, the decomposition of leaves will be affected. Living matter is aided in the decay
process by elements such as humidity and precipitation (Poté et. al 2005). The exact
effects that specifically winter precipitation has on leaf decomposition in Rock Canyon,
Utah are unknown. Samples will be observed and collected from different sites within
Rock Canyon and compared with each other in order to measure the effects precipitation
and water presence has on the rate of decay. The samples will be drawn from the Quercus
gambelii species of tree, more commonly called the Gambel Oak. This will help
determine whether or not leaf decomposition is aided or hindered by reduced
precipitation in the winter. Leaves will be collected from different environments, such as
from a ravine, side of a mountain, and by the road.

Title: Impact of Water Velocity on the Banks of the Provo River near Provo, Utah
Abstract:
I compared three sections of the Provo River with differing river velocities: rapid,
average (relative to the river as a whole,) and near-stagnant. The disparity in current
speeds correlated with variation in topography and both distribution density and variety
of new plant growth on the immediately adjacent river banks. Where the river velocity
was higher, new plant growth was limited and the banks were more rocky and hilly,
indicating the likely impact of erosion. In the area where the water was virtually stagnant,
erosion had very little impact, and the distribution and variety of plant life was greatly
increased.

April 2011.
Abstract:
I wanted to go to a moving body of water and a still body of water in order to
evaluate whether moss grows more abundantly with moving water or still water, and
what differences the moss have at both different types. I went to Provo River to get
samples and pictures from the moss at a moving body of water and I went to the duck
pond and Utah Lake to get the samples from still bodies of water. This experiment was
done to learn more about moss and to learn under what circumstances moss grows the
best. Also to learn what characteristic the moss needs to survive in different
environments. I found a very large variety and abundance of moss at the Provo River.
The moss was mainly located near the waters edge and on rocks dirt and trees. There was
also moss on the rocks and branches in the water.Utah Lake and the Duck Pond both had
almost no moss growing around them and what little moss was there was not very
diverse. I found moss on the rocks right next to the waters edge and a lot of pond scum
completely covering all of the rocks that were under ground. Based on my observations
moss grows the best by running water and very little by standing water. Moss also grows
the best where the sunlight is not as direct.

The difference of mallard duck’s sensitivity between male and female
Insu Kim, Brigham Young University, Provo, Utah 84604 Email: insu91@gmail.com
Abstract: Most of wild animals are really sensitive to changes in their habitats by other
animals, which could threat their lives or habitats. Mallard ducks are representative
winter migratory bird, and because it’s a species of migratory birds, mallard duck have a
keen sense to recognize direction and territory of their habitat. This information gave me
the idea of researching the sensitivity of mallard ducks. To research the sensitivity of
mallard duck, I went again to Paul Ream Wilderness Park to find the mallard ducks on
March 23th, 2011. As I’m working on the experiment, I could get the average distance
between mallard duck and the subject of research. Based on these data, and if I assume
that the distance shows the sensitivity and sense of closeness, I could conclude that
female ducks are more sensitive than males, and the mallard ducks are more familiar with
small children than big adults.

Abstract:
Experiments were conducted at the Paul Ream Wilderness Park and BYU campus
duck pond in Provo, Utah. Mallard ducks’ reaction to different kinds of common snacks
that human eats was observed. The purpose was to test the taste preference of foods that
human give to the mallard ducks (anas platyrhynchos) and that they prefer some snacks
over others snacks. To demonstrate this, three different snacks found common in
households were given to a group of mallard ducks in different location, which included
potato chips, Cheerios, and Toy Story 3 cereal. The quick reaction and the competition
of eating different kinds of snacks were observed. There wasn’t much difference in the
average time ducks took to eat 10 pieces of different choice of snacks. Sweet wasn’t
much different and concluded that ducks can’t taste sweet like humans do. However, as
further the experiment went, ducks seemed to reject saltiness. Through social learning
many other ducks chose to reject potato chips and preferred to eat either cheerios or Toy
Story 3 cereal.

The Effect of Salinity on the Sprouting of Kidney Beans
Frederik S. Kleiner, 1950 N Temple View Dr #320, Provo, UT, 84604
Email: Frederik.kleiner@gmail.com. Submitted: April 4, 2011
Abstract
Salinity can have a profound impact on the development of plants. During
germination, plants are especially sensitive to substrate salinity (Houle 2001). Many areas
of the world are now affected by high levels of salinity, either due to location, such as by
the ocean, or poor irrigation and water management. It is therefore important to know
what levels of salinity different plants can withstand and still produce fruit. This topic has
been of interest for some time. Charles Darwin tested the survivability of seeds in salt
water and their potential for growth after then being planted in soil with fresh water. This
experiment looked at the germination rate of the kidney bean (Phaseolus vulgaris) after
irrigation with water of different salinities. I planted ten different beans into soil and
divided them into five groups of salinities. For one week the beans received ten milliliters
of water daily and after the time, the length of the root germinating was measured. I
predicted that only the freshwater beans would have any substantial growth.

The influence the temperature has on the migration pattern of diurnal birds (Aves)
Emily Kleinkopf, 19 Bowen Hall, Provo, Utah 84604, Email:
emilykleinkopf@gmail.com
Abstract
Experiments were conducted in and around the Provo area. Birds were
observed on various days, in different habitats, in different temperatures, and in different
weather conditions. The purpose of the experiment was to test the hypothesis that once
the temperature reached above 30 degrees Fahrenheit, the birds would start migrating
back to Utah, therefore concluding temperature as their migratory impulse. To discover
the effect the temperature had on the migration of the birds, I went to different locations
that included the Provo River and Spanish Fork, and observed how many birds there were
over a period of an hour. After every observation period I wrote down exactly how many
birds I saw, the exact temperature, and any other weather factors like snow or rain. Over
the period of the two months the data shows that as the season progressed the amount of
birds observed during the hour allotment also increased. Nevertheless, the concurring
trend according to the concluding data suggests that the migratory impulse is not mainly
based on the temperature but the actual time of year and type of weather has a more
direct effect. According to studies temperature is only a part of the reason why birds
migrate. Some other factors that catalyze migration are wind currents, species of bird,
time of year, and breeding patterns.

Abstract
Why are there so many types of things? When I walk around BYU campus, I am surrounded by
hundreds of trees. They are all different shapes and sizes. What causes one tree to grow larger,
greener, and faster than another? After hiking up the Y one time, I began to realize why certain
trees grow larger than others. From such a high elevation, I quickly realized my surroundings and
what it would take for a plant, animal, or tree to maintain an effective habitat up there. In this
experiment I am going to find out scientifically exactly how much of an effect elevation and
precipitation has on plants, specifically the Abbotswood Potentilla (Potentilla fruticos). Does
elevation and/or precipitation really play as huge of a role as we think in the growing process?
And if so, how much of an effect?

Abstract:
I studied the effects of moisture on both the particle size distribution of
fractionated biomass (corn stover, switchgrass, and wheat straw) and the process in which
the biomass is converted into biofuel. Using assistance and materials from Idaho National
Laboratory, I used a fractionation mechanism to break apart both moisture-rich and dried
biomass samples, after which I seperated the samples into various screen sizes. Moisture
was determined to play little to no recognizable effect to the particle size distribution, and
was unable to be determined if it played any effect in relation to the biofuel process. Corn
stover was determined to have the largest particle size overall, suggesting that corn stover
would be the most moisture rich, and therefore hardest to fully convert into useable
biofuel.

Aggression and Boldness in Song Sparrows in Residential and Nonresidential Areas
Whitney Ann Landon, 236 E 2230 N Apt 1, Provo, Utah 84603 Email: wlandon@byu.net
Abstract
Due to differences in surrounding populations, ambient noise, available resources
and inhabitable territories between rural and urban areas, song sparrows (Melospiza
melodia) adapt to their surroundings in order to become most successful in their chosen
habitat. Song sparrows were observed in two locations, one residential and one
nonresidential on the same day. They were especially observed for differences in song
(related to the presence or absence of ambient noise) and differences in boldness when
confronted with an approaching human. Another area of observation was related to their
diet and comparative size. I theorized that urban sparrows have more physical resources
but must adapt to the presence of other challenges such as ambient noise and presence of
humans.

Abstract
I studied how changing weather affects Aves’, birds, eating habits looking at
temperature and precipitation in Rock Canyon near Provo, Utah. With the help of hand
made bird feeders I attempted to attract Western Scrub Jay’s (Aphelocoma californica),
Chickadee’s (Poecile atricapillus), and Red-breasted Nuthatch’s (Sitta canadensis). Then
the amount of bird seed eaten was measured at the end of each day. Unfortunately, all of
my results were negative with none of the birds eating any of my bird seed. Possible
reasons for this could include the birds having a reliable food source, or the weather
never being warm enough for the birds to forage. My results therefore showed that if
birds have set foraging behaviors they are independent of the weather. Other’s research
showed a correlation between weather and foraging habits, though they further tested
humidity, solar radiation, and wind’s effect on the birds.

Y Mountain’s Elevation and Its Effects on Vegetation
Brad Langfoss, Provo, Utah 84604 Email: blangfoss92@hotmail.com
Abstract
In this study, I found the factor that affects the living conditions of vegetation on
the side of a mountain. I observed that as the elevation on the side of the mountain
increased, there were fewer plants in those areas. From my 3 soil samples (Table 1)
taken on the mountain, I found that elevation does not directly affect the soil nutrients as
the vegetation is higher up. However, elevation may affect the temperature,
concentration of oxygen available, and an overall harder climate to grow in compared to
climates at lower elevations.

Abstract:
I conducted experiments to determine whether the temperature of the water affects the
feeding habita of fish. 18 common goldfish, Carassius auratus auratus, were bought and
placed in a 20-gallon tank filled with fresh water. They were fed on 6 different days. On
each feeding day the water temperature was maintained at a different temperature. They
were fed the same amount of food every time and after thirty minutes the food was
measured to find how much they had eaten.
It was found that water temperature had little effect on how much the fish ate. They ate
just as much food in cold water as in warm water. It appears they eat as much as they can
in any condition.

Influence of color in the choice of feeder by resident birds in Provo, Utah, USA
Tyler R. Langlois, 1223 May Hall, Provo, Utah. 84604 Email: mr.langlois@gmail.com
Abstract
It seems it is hard to find conclusive research that has been done regarding what
color of birdfeeder birds prefer. By determining what colors of feeder are most appealing
to birds, feeders can be colored accordingly to effectively attract birds better and promote
the health and survival of avian species. I hypothesized that of white, red or green, birds
will prefer red feeders. Multiple feeders of the differing colors were placed alongside
each other in different locations around Provo. Data was gathered on the amount of bird
seed eaten in each birdfeeder and was be compared to the amount of bird seed eaten from
other birdfeeders. Results were calculated by averaging together the amount of birdseed
eaten from each birdfeeder of the same color into one grand average total of birdseed
eaten for that color. By comparing the amount of birdseed eaten from each of the three
colors of birdfeeders, I drew my conclusion that the color red on birdfeeders is preferred
among birds in Provo.

ABSTRACT:
There are many species of trees in Utah. The canyons and Mountains surround
Utah valley, varying in different altitudes. This study is to show how latitudinal elevation
affects the growth of leaves on (Acer platanoides, Acer grandidentatum and
Populus tremuloides). Samples from each tree were photographed and recorded from
different altitudes around Provo to compare and study. Data from trees in Provo canyon
and other places with higher elevation were collected as well as data from trees in the
valley with lower latitudinal elevation. The data collected was recorded on a table to see
and compare. It was found that trees in higher elevation seemed to bud faster than the
trees in the valley. It was also found that most of the trees I sampled for this study were
specifically planted in certain elevations to handle the environment they grew in.

Causes of deciduous trees losing their leaves in the winter
Morgan L. Leany, 3222 David John Hall, Provo, Utah 84604 Email: mleany@yahoo.com
Abstract: Observations and identifications were performed outdoors in Wyview
apartments and around Helaman Halls in Provo, Utah. The purpose of of this experience
was to discover which trees lose their leaves in the winter as opposed to which ones do,
and the hypothesis that it is some form of protection or survival method for the trees. To
find the answer I identified a few different types of trees around the area and researched
them using specific books. The two main types of trees that I used for this experiment are
the Maples and the Pines. After identifying these two different types of tree families I
found the differences between them and also found that the reason why Maples lose their
leaves is because they are a form of Deciduous trees and it is a hibernating tactic to help
survive during the winter.

caused by insect irritation. We collected rabbitbrush (Chrysothamnus nauseosus) with
galls from the side of Utah Lake in February and Springville in March. I examined these
galls under a microscope and light, and charted my observations. Through this study I
found that galls do grow on rabbitbrush (Chrysothamnus nauseosus) in Utah County
during February and March. I studied these galls using a microscope and light and I
identified insect larva in the center of some of them. I also found some small winged
insects inside of another gall. My observations confirmed past research showing that
galls are found on rabbitbrush (Chrysothamnus nauseosus) during winter months in Utah
(McArthiir, Tiernan et.al. 1979). Galls on rabbitbrush are created by irritation to the
plant from small insects, some of which are tephil flies (Dodson, 1991; Wangberg, 1978).

Abstract: A common phenomenon found among birds is their tendency to sing at dawn.
Common hypotheses as to why this behavior occurs at dawn is that atmospheric
turbulence is least at dawn, thus providing a better environment for transmitting auditory
signals such as birdsong (IBIS..). In this study, the amount of bird song activity shortly
before and after the official time of sunrise was observed in two different environments in
Provo, Utah. Data was recorded from these observations and then used to make
comparisons on the effects of time and environment on the dawn chorus. I hypothesized
that there would be more song activity after sunrise and in a less urban environment.

Abstract
The carpenter ant can be found around the Strawberry Reservoir in Utah. This
ant’s scientific name is Camponotus. They are found in different variety throughout
Utah. During this study, research was done to learn more about the specific species of
carpenter ants found in Utah. I wanted to find out if anyone before me had studied these
carpenter ants native to Utah and if so, what studies were done that I may benefit from
while performing my own study. The knowledge that ants work together as a colony and
that each ant has its own duty to perform is well known. My thoughts while doing this
study was to find out how the carpenter ants around Strawberry Reservoir had adapted to
their surroundings and how they utilized the resources available to them. These ants
were observed for a few hours each visit to Strawberry Reservoir so as to see how the
colony reacted to its surroundings, including plant life and other insects as well.

Elevation Influence in the length of needles on a Pine Tree (Pinus Ponderosa) in Provo
and Salt Lake City, Utah, U.S.A.
Jimmy McDonald, 2203 May Hall, Provo, Utah 84604 Email: jsmcdonald@triad.rr.com
Abstract
The length of pine needles on a Pine tree (Pinus ponderosa) have been known to vary
slightly between species, and even individual plants of the same species. The exact
causes of these variations have not been exactly pinpointed down to one overall specific
cause, the purpose of the experimentation was to test what was a determining factor in
pine needle length. Specimens of pine needles have been extracted from various locations
in both Provo and Salt Lake City, Utah. Key factors that were studied included elevation
of the pine tree, proximity to water, and proximity to civilized areas. The needles were
extracted both off of the tree, near the trunk where they were the longest, and from dead
needles found at the base of the tree. Each needle that was recorded was inspected to
make sure that there were no breaks, and that it was a full needle, not cut short in any
way. The trees from which the needles were extracted were also checked to all be of the
species Pinus ponderosa, so as not to gather incorrect data due to specimen
differentiation.

Migration Habits of Utah Birds
Marci McIntosh, 8243 N 9550 W, Lehi, UT 84043 Email: marci_mc@byu.edu
Abstract
Observations were made watching birds in three distinct locations: Canyon Glen
(canyon location), Utah Lake (large body of water location) and Jordan River Parkway
(stream and woodland location) to see what type of birds make Utah their home for the
winter, and the type of birds that migrate into the Utah area for spring and summer.
Multiple bird species were identified and observed in the three areas. Longer research is
recommended (6 month timetable: January to June or July to December) to further
understand the migration pattern and be certain on the differing bird habitations that are
at home in Utah throughout the year. Since the three month time period was an
insufficient time for a solid conclusion, I will be referring to the expertise of local Utah
birders for history and patterns that should have taken place.

The effects of temperature and soil on the decomposition of food as well as what types of
food decompose the quickest
Kari L. Merrell, 2107 Stover Hall, Provo, UT 84604 Email: karebear641@hotmail.com
Abstract
This experiment on decomposition was conducted in Provo, UT. Factors of
decomposition, including temperature and the presence of soil were observed as well as
comparing different types of food and how they compare in decomposition. This
experiment was conducted to further understand different properties of food spoilage and
to increase awareness of being wasteful of food as it takes time to decompose. Three of
the same groups of food (including an apple, banana, piece of bread, and French fries)
were placed at three different locations and results were recorded. It was observed that
higher temperatures speed up the decomposition process, soil speeds up the
decomposition process as well, and that fruit decomposes the quickest out of the observed
foods.

Temperature and its affect on crocus opening and closing
Ryan C. Merrill Provo, Utah 84604 Email: ryan.merrill215@gmail.com
Abstract
This study was conducted by watching and recording the opening of the Crocus
flower and measuring what temperature they began to open at. I found that the flower
favored the range from 10 degrees Celsius to 20 degrees Celsius. As the day would come
to a close and the temperature would drop the flower will close its petals to protect itself.
This is an important evolutionary achievement because it blooms at the end of winter and
beginning of spring before the last couple cold flashes are done for the year.

Email: stephaniemerrill91@gmail.com
Abstract. For my nature experience I decided to study the forsythia bush outside my
parents home in Provo and watch it bloom and then compare it to the temperature. I then
studied and learned how temperature and rain impact the date of when plants bloom. I
took pictures of the bush throughout the blooming process and also recorded the daily
temperature.

Abstract
The golden ratio is very prevalent in architecture and has been supposed to be a
natural law. I set out to verify this by measuring the branches of North American Aspen
Trees (Populus tremuloides) directly above where they branch out. I used a generic tape
measurer to measure the circumference of each of the branches. The golden ratio was not
found to be prevalent in the circumference of North American Aspen Trees.

The Influence and effects of Color and size in the diet of rainbow trout (Oncorhynchus
Mykiss) During Winter
Shelby Miller, 1201 N 850 W, Provo UT, 84604 Email: jsmiller51@gmail.com
Abstract:
Experiments were conducted in Deer Creek Reservoir in Provo Canyon, Heber,
UT. Baits of varying color and size were used while ice fishing. The purpose was to test
the hypothesis that Rainbow Trout most frequently search for food that is of a color
within the wavelengths of 380-420nm and 700-740nm or purple and red. To test this
hypothesis, lures and baits of colors from many different parts of the light spectrum were
used as well as lures broken into three categories of small, medium and large sizes. The
numbers of bites will be recorded along with the color and size of the lure used, the bait
tipped on the lure, the date, the location, and the time of the hit. It is noted that there was
a distinct pattern and tendency for the Rainbow Trout to most frequently strike the pink
bait and lures and the size of the lure that was most effective grew increasingly smaller as
the winter continued.

How proximity to a constant source of water affects tree growth
Abstract:
This nature experience happened in provo Canyon in Big Springs Park. Tree growth was
observed via a core sampling taken at the trees' natural habitat. The purpose of this
experience was to see if the proximity of a tree to a constant source of water would affect
its rate of growth. The specific tree species observed was Populus fremontii (Freemont
Cottonwood). To measure this, a tree core sampling was taken from two different
Cottonwood trees and the width of the rings in the core sampling was noted. The outcome
showed that the tree closest to the constant source of water did in fact grow at a faster rate
than the tree further away.

The birds (Aves) located in Stewart Falls and Sundance, Utah
Adam Morrow, 2119 Merrill Hall, Provo, Utah 84604 Email: amorrow92@gmail.com
Abstract:
Experiments were conducted in Sundance, Utah and Stewart Falls, Utah. Birds
(Aves) were observed under natural conditions at both locations. The purpose was to test
the hypothesis that human presence in Sundance would affect the number and rarity of
certain birds as opposed to that of the more secluded area, Stewart Falls. To demonstrate
this, birds where identified and recorded according to which area they were found. It was
determined that varieties of birds found at both locations were very similar, and that most
birds found were classified as common. The explanation to this I believe is during the
winter months, only permanent residents can be found, which are mostly commonly
found birds.
Key words: Sundance Utah, Aves, rarity, location.
Effect of Time, Temperature, and Weather in Bird Song in Rock Canyon: Provo,
Utah, U.S.A.
Katie E. Nay, 657 North 400 East Apt. G2, Provo, Utah 84606 Email:
incrediblekate@gmail.com. Submitted April 4, 2011.
Abstract. This nature experience is a series of observations made in Rock Canyon in
Provo, Utah to see if time, temperature, and weather have an effect on birdsong. I brought
pen, paper, and a camera each time and took observations, pictures, and video of the birds
I saw and heard. I also took note of the weather surrounding me. I found that many more
birds were singing when I observed earlier in the morning, but weather might have had an
effect and this conclusion cannot be made. I was able to identify four birds after the
experience with the data that I had collected. Key words: birds, birdsong, temperature,

ABSTRACT
Mosses grow abundantly in many different areas and habitats including Utah.
These plants commonly grow on rocks and trees. I measured the growth of two samples
of moss and tested for samples on eight different trees. I also measured the average
temperature and precipitation as well as elevation of the samples. These measurements
were taken over a period of four weeks. My hypotheses differed from a number of expert
studies. The differences in my results may have been due to the shorter time scale,
differing location, and differing species of moss. Also, my measurements may have not
been as precise as needed.

The effect of tree growth with respect to elevation and water source- (Dendrochronology)
Alexander R. Nelson, 679 Wymount Terrace, Provo, Utah 84604 Email: alnelson8@comcast.net
AbstractAll trees grow at different rates. A tree grows by increasing height (apical growth) and by
increasing in breadth (radial growth) (Stokes 1986). The growth of a tree depends on the amount
of water that it receives in a given year. In wet and humid years, trees grow more while in dry and
cold years their growth is almost non-existent (Lendering 2007). Each year a new ring is formed
and is a key indicator of the amount of growth the tree experiences. This ring varies in width due
to the amount of water the tree received during that year. Thus the wider apart the rings are from
one another, the more water the tree received and the more the tree grew in the given year. For
this study I took core samples from 3 different trees, the Rocky Mountain Maple (Acer glabrum),
the Gamble Oak (Quercus gambelii), and the Ponderosa Pine (Pinus ponderosa), in 3 different
locations, Provo Canyon, Provo River, and Wymount Terrace (BYU family housing complex).
Using three different locations gave three different perspectives of growth according to the water
sources present. The rings of these samples were measured to compare the growth of each tree
with respect to its location. My hypothesis was that because trees grow more with more water, the
trees along the Provo River would have a greater distance between tree rings.

Bubblybouncybrunette@yahoo.com
Abstract:
Experiments were conducted in Provo, Utah. Bananas(Musa acuminataare) were
observed at different temperatures to see what temperature would make them ripen faster.
The purpose was to test the hypothesis that Bananas that are left outside would ripen
faster. To demonstrate this bananas were left in the fridge, freezer, and outside and the
skin color of each banana was checked every twelve hours for seven days. Then after
seven days the bananas were taken out and a skin color, texture, and scent test was
performed on each. It was determined that bananas that are left outside ripen slower than
the bananas that were left in the fridge and freezer. It was also found that the ripening of
the bananas was not consistent.

Thermal influences on five tree species in Rock Canyon: Provo, UT, U.S.A.
Michelle Nicolas, 109 A. Richards Provo, UT 84604 email: chachatango@gmail.com
Abstract
Experiments were conducted in Rock Canyon in Provo, Utah. Five different types
of trees were included into the study: Big tooth Maple (Acer grandidentatum), Douglas
Fir (Pseudotsuga menziesii), Gambel Oak or Scrub Oak (Quercus gambelii), Mountain
Ash (Sorbus scopulina), and Engelmann Spruce (Picea engelmanni). Observations
revealed the influences that seasonal temperature changes have on the local trees’
appearance and behavior. The purpose of this experiment was to determined if the
organisms reacted to the changes in their climate. In order to observe this, I went to the
location, identified the trees, and then recorded the trees’ reactions to the thermal
changes. It was determined that each of the different tree specimens did in fact react to
the changes in the temperature. The changes in the trees’ behavior and appearances were
depended on the type of tree observed.

Preferred Water Flow Speed of Caddisflies (Insecta: Trichoptera) in Right-hand Fork of
Hobble Creek River in Hobble Creek Canyon
Shaelee Nielson, 127 Robison Hall, Provo, UT 84604 Email: bilbo100@gmail.com
Abstract
Some stream animals prefer to live in fast flowing water, and others prefer to live
in slow flowing water. I wanted to see what speed of water flow caddisflies preferred. My
hypothesis was that they would prefer slower flow of water. We did our experiment on
March 19th with supplies from the BYU supply room. We then measured the flow of the
water speed and then counted the number of caddisflies beneath rocks and that got caught
in our bug-catching net. We found that caddisflies prefer to live on the rocks in the faster
flowing water.

Using bark growth patterns to identify trees of the Prunus genus in the winter season
Spencer J. Nielson, 988 South 400 East, Orem, UT 84907 e-mail:
spencerjnielson@yahoo.com
Abstract
Extensive observations were undergone to locate and identify trees of the Prunus
genus. The purpose of these observations was to find what characterized trees of the
Prunus genus from tree species from other families. For me, the intention of this project
was to find similarities among the species so that the genus may more fully be
distinguished. The hypothesis going into this experiment was that tree species of the
Prunus genus have such bark patterns that they could be divided among other genus.
After tracking down numerous trees, photographs were taken periodically to study
changes within the structure of the Prunus trees’ barks. I found that the identification of
these trees in winter can be determined from the distinctions of their bark, buds, and pits.
Effect of slope aspect on spatial patterns of trees of the genus Juniperus

babynoonan5@gmail.com
Abstract
I studied the spatial patterns of trees belonging to the genus Juniperus in a section
of Rock Canyon, which is located in Provo, Utah. I hiked a portion of Rock Canyon
during April 2011 and counted the number of juniper trees that grew on the north-facing
side of the Canyon and the south-facing side of the Canyon at or near the elevation of the
trail. Along the first half of my hike, I identified three juniper trees on the north-facing
side of the Canyon and one on the south-facing side. Along the second half of the hike, I
identified one juniper tree on the north-facing side of the Canyon and three on the southfacing side. This indicates that other factors may contribute to the spatial patterns of these
trees.

Abstract:
Experiments were conducted in the Provo river of Provo, Utah. I was testing to see the
difference between the river plants. I was observing their features to see if there was any
common identifier besides the fact that they all can survive in water. The common or
uncommon traits that I looked for was color, shape of the leaves, shape of the plant as a
whole, roots, and the plant’s location along the river. I went along the river and identified
the most common plants on the river. As observed, I found three specimen that were the
most common out of all of the plants that were on the river. For location I was also
observing the current flow and what plants were in which current; whether it was a still
current or a fast moving current. The first plant collected was algae, the second was a tall
grass, and the other looked like a clover.

Oyanedel.t@gmail.com
Abstract
The aim of this study was to determine the effects of spices in the amount of food
intake of the garden snail (Helix aspersa) under strictly controlled conditions. The study
was performed on snails removed from aestivation. Records of their food intake with
different spices in lettuce were carefully weighed and recorded during four weeks.
Results show that exposure to sugar, salt, garlic, and pepper in their food results in
different amounts in their food intake. A control group without any spice
supplementation was run parallel. The control group and the experimental group #1
(lettuce/sugar) had a superior food consumption, whereas the other groups registered a
lesser amount in their food intake. During the experiment the snails were kept in plastic
containers and they did not have access to soil.

Abstract
I observed the decomposition of bananas at six different distances from
the Provo River to see if the distance from a water source affected the rate of
decomposition. I recorded these observations and compared each of the bananas to the

The effects of rivers and flooding on cottonwoods (Populus fremontii)
Megan E. Paravato, 876 E 900 N #11, Provo, Utah 84604. Email: twocarsm@gmail.com
Date: April 2011
Abstract:
After walking along the Provo River I noticed the large amount of cottonwood
trees growing right into the river. I was able to observe and research to figure out how
they have adapted to thrive on so much water, deal with floods, and provide for other
organisms in their community. Cottonwoods are an incredibly successful tree when
growing along a water source. They need large amounts of water since they are so large
and grow so fast. They use their roots to obtain groundwater that is replenished by the
river, rainfall, and nutrients. They break as a result of storms or decay because
cottonwood is weak from the beginning. Their broken branches and the algae that grow
on them as a result of moisture are able to play a role in providing needed resources such
as food and protection for their community.

Abstract
Every third day, experiments were conducted at the base of Mount Squaw Peak
beginning on February 20th until March 31st from 12:00 PM to 1:00 PM. During that
time period, the soil an air temperature was recorded along with the weather type that
day. Arthropods were searched for as bushes were shaken, rocks were overturned, and
dead grasses and leaves were parted. The purpose was to discover when arthropods
return to life after the winter, and how the atmospheric conditions effect them during that
transition from winter when bugs are scarce to spring when they are seen everywhere.

The effects of elevation upon caddisfly (Trichoptera) larvae case length
Joshua A. Peterson, 1077 E 1150 N, Orem, Utah 84097 Email:
peterson_587@hotmail.com
Abstract
Caddisflies (Trichoptera), when in larval stage, live in tube-like structures called
larvae cases. Collections of these larvae cases were made at different elevations along
Utah’s Provo River. This was to verify if there is a negative correlation between
caddisfly larvae case length and elevation. Data taken from the three research locations
used show that as one ascends the Provo River, the mean length of larvae cases
decreases. While this does support the proposed hypothesis, several possible
confounding variables in the form of habitat and species differences made it difficult to
fully establish this relationship. Because of these, results of this study were inconclusive.

Diversity of plant communities on the edges of the east and west shores of Utah
Lake.
Janae Pettit, 914 S. 635 W., Orem, UT 84058. thomas.pettit@mstarmetro.net. Submitted
March 2011
Abstract: The shores of Utah Lake differ abiotically on the edge of the littoral zone on
the east and west sides of the lake. The littoral zone on the east edge of the lake is wide
and the plants grow in the water where the slope is gentle, the water shallow, and the
temperature warm. The littoral zone on the west edge is very narrow so there is little
room for plants to grow in the water. The slope is steep, the water deep, and the
temperature cool. These differences would indicate that different plants grow in the
differing conditions. Observations were made at three locations at the edge of each of the
east and west shores of the lake. Six major plant species were chosen and then looked for
at each of the sites. Three are native plants and three invasive species. When data was
compared, the three native plants were found only sparsely on the east edge of the lake.
And two of the invasive plants were abundant on the west edge. The abiotic features
have not changed over the past 100 years, but the invasive species have choked out the
natural plants and have become the predominant species at the edges of Utah Lake.

Affect of altitude change on plant diversity on Y Mountain in Provo, Utah
Krista Philips, 2122 Hinckley Hall Provo, UT 84604, misskristaphilips@yahoo.com
Abstract
The affect on plant diversity by elevation is proposed by researchers to be
affected by other elements other than elevation. I predict that the diversity of plants
decreases as I go farther up a mountain and that most of the plants are scrubs, and not
many trees. I did an experiment by hiking Y Mountain to accumulate photos of different
plants on three different elevations of the mountain comparing what I found on each
level. I determined the different elevation levels and identified the plants I found at each
level and compared the results as to what level had a bigger diversity of plants. There
were about 13 different plants at the top elevation level compared to the 15-20 I found on
the bottom and middle elevation levels. I concluded that there was less diversity of plants
as I went up Y Mountain. I found that part of the change was due to the climate
conditions in the areas of elevation of the Mountain and possible global warming effects.

Behavioral adaptation and domestication of bobcat (Lynx rufus) in Blackfoot, ID USA
Hunter B. Phillips, 2060 N 131 W Apt. 214, Provo, UT 84604
Email: hunterphillips@gmail.com
Abstract:
I conducted my experiments in Blackfoot, Idaho. A bobcat (Lynx rufus) was
observed in a human residence, alongside a domestic Siamese housecat (Felix
domesticus). The purpose of the observations was to test the typothesis that a bobcat,
taken from the wild, will adapt to its new environment and begin to more resemble a
housecat in behavior. Observations took place over the course of eight weeks, with data
being collected every seven days, on each Sunday at 3 p.m. To demonstrate the
differences between the bobcat and housecat, during each observation period, the two
cats were fed their afternoon meal, and introduced to a human stranger. During this time,
the bobcat transitioned from being fed raw chicken meat to a generic hard-kibble cat
food. By the end of the eight weeks, the bobcat had lost or greatly diminished certain
behavioral “tics” that were signatory of its natural environment. I can offer no
explanation as to why this change occurred, but the bobcat’s behavior indeed began to
resemble that of the housecat by the end of the observations.
The influence of water temperature on the abundance of Ephemeroptera (Mayflies) in the
nymph stage, in the Provo River, Provo, Utah, USA.

Abstract:
Initial research was conducted, studying mayflies in their nymph stage in the
Provo River, Provo, Utah, USA, in relation to water temperature. This preliminary study
will aid in later, more refined study and analysis of the ecosystems of the Provo River
and surrounding area. Temperature readings and mayfly samples were collected from
three locations, and taken to Dr. Nelson’s biology lab for positive identification and
examination. The data collected indicated a progressive reduction of mayflies as the
readings continued up the Provo River, but further research and analysis will be needed
to remove possible variables from affecting the data.

The Effect of Altitude on the Acidity of Rose Hips from Rosa Woodsii (Rosaceae) at
Rock Canyon, Provo, Utah
Abstract
Rosa Woodsii (Rosaceae), commonly called Wild Rose, or Woods Rose, is widely
found at the mouth of Rock Canyon, in Provo, Utah. Wild Rose is a shrub of 2 to 5 feet in
height, and produces Rose Hips, one of nature's greatest sources of Vitamin C. Three
samples from three different elevations are observed and the pH of their Rose Hips
analyzed. The chosen elevations are 5,000 ft, 5,200, and 5,400 ft, as determined with the
use of an Altimeter. The affects of elevation on this bush and its fruit, Rose Hips, are
determined; each rose hip at each of the three elevations have a pH of 4, and thus it is
concluded altitude plays little or no role in its pH. Studying both the plant and its fruit has
great significance pertaining to health. As we better understand the properties of rose
hips, we will be able to more fully utilize its vitamins and health benefits. And, equally
important, the study of Wild Rose's optimal growing conditions will help us preserve this
important species. (200 words)

Differences between close and distant observation of the humpback whale (Megaptera
novaeangliae)…does nearness of the observer affect whales’ behaviors?
M. Harindranto Rasolo, 167 N 1120 W, Apt U203, Pleasant Grove, UT, 84062
Email: hari.rasolo@gmail.com
Abstract
I traveled to Hawaii from February 20-27, 2011 to observe the above-water
behaviors of migrating humpback whales (Megaptera novaeangliae). My goal was to see
whether or not the nearness of the observer changed the types of behaviors acted out by
the whales above the surface of the water. I went on two separate expeditions on a small
boat that allowed a nearness of up to 300 yards, which is the maximum closeness for
boats as dictated by Hawaiian law. These expeditions afforded a total of 240 minutes
over the 2 expeditions of whale viewing time and always took place in the afternoon from
2:30-5pm. The whales’ behaviors were documented and recorded. A total of 19 whales
were seen from the boating expeditions. I then compared this data, to data observed,
recorded and collected by observing whales with binoculars from the beach on 3 different
days for 2 hours at a time at the same time of day. I was able to observe a total of 52
whales over the 6 hours of observation and record their above-water behaviors. The
whales observed at a distance (up to 3 miles from shore with binoculars) displayed much
more above-water activity and behaviors, than those whales observed from a small boat
at a closeness of 300 yards. This observation leads me to believe that the whales can
definitely sense the presence of the observer and that this presence leads to inhibition of
the whales’ natural above water behaviors.
Keywords: humpback, whales, behaviors, observers, and inhibition.
The influence of anthocyanins on red osier shrubs (Cornus Stolonifera)
Jayson Richards, 3209 Merrill Hall, Provo, Utah email: jaysonrichards8@gmail.com
Abstract:
I conducted my experiment in the Provo River of Provo, Utah. I measured the
levels of anthocyanins in twenty different red osier shrubs (Cornus Stolonifera). The
purpose was to test the hypothesis that higher anthocyanin levels promote growth in
Cornus Stolonifera. To demonstrate this, I measured shades of red in Cornus Stolonifera
according to a printed scale. Additionally, I measured height with a measuring stick and
the widest visible stem of the shrub with measuring tape. Shades of red were analyzed
alongside height and largest circumference. I determined that higher anthocyanin levels
did indeed promote growth. However, there is a negative correlation between measured
anthocyanin levels and base circumference of red osiers.

Winter behavior of Mycorrhizae ectomycorrhizae fungi in dormant deciduous trees in
Ashley National Forest: Midvale, UT, U.S.A.
Spencer M. Richards, 1200 North Terrace Dr. Apt. 329, Provo, UT, 84604 Email:
spencerrichards@live.com
Abstract:
Experiments were conducted in the Ashley National Forest of Midvale, Utah.
Mycorrhizae fungi were observed in their natural environment during the winter months.
Due to the fact that many species of Mycorrhizae may be present on a single plant, no
one particular species was identified. The purpose was to better understand the if these
fungi remain active during the winter when their plant counterparts enter dormancy. In
order to examine this relationship, five deciduous trees with active Mycorrhizae colonies
were identified. After soil type was initially decided, samples were taken from the roots
of each tree every four days, and moisture and temperature measurements were recorded.
Mycorrhizae colonies showed a positive response to warmer temperatures and moderate
precipitation, and less of a response to colder weather and dryer conditions. Despite the
general cold and dry conditions of the winter season in Utah, it was concluded the
Mycorrhizae maintain activity during this time. However, it has yet to be determined
whether or not the symbiotic relationship between fungi and plant continues during the
winter season.

Elevation and Its Effects on Plants in Utah-more specifically: Y Mountain
Allison Rietz, 2108 Stover Hall, Provo, UT 84604 Email:allisonrietz@gmail.com
Abstract:When a seed is planted, many factors contribute to whether or not it will
survive. These include the type of seed, amount of sunlight and water available, and the
elevation at which it is planted. In this study, I took samples of plants at three different
elevations, starting at the base (5147 ft.), continuing on to Turn 3 (5582 ft.) and finally to
the bottom of Y (6084 ft.). These points roughly marked the beginning, midway, and
ending points of the hike to the Y, on Y Mountain in Provo, UT. I collected samples at
each location, noting the differences in type, coloring, and height of the different plants.
Since plant type depends on where it is planted, I predicted that the higher I went, I
would find less variety and shorter plants. Keywords: Y Mountain, elevation, shrubs.
Behavior of Largemouth Bass in Deer Creek Reservoir during January
Abstract
Largemouth bass (Micropterussa lmoideas) can be found in most states but it is
during winter that most fish aren’t active. When winter comes around they like to slow
their activity down and their metabolism slows down and they do not have an extensive
desire to consume. As winter sets in they move to deeper waters. Measurements will be
taken in Deer Creek Reservoir to find out why they stay for the winter seasons and do not
hibernate or move to more a more fitting location.
Circumference size of pine trees (Pinaceae) throughout Provo Canyon, Utah
Steve M. Samson, 320 N. 1080 E. Apt. 201, Provo, Utah 84606 Email:
samson52@byu.net
Abstract:
Scientific observations were conducted in Provo Canyon, Utah. Circumference
size of pine trees (Pinaceae) were measured and recorded at breast height (130 cm). The
purpose was to see the overall trend of pine tree size throughout Provo Canyon at several
parks (Canyons, Vivian, South Fork, and Nunns). The observation was conducted by
attending the parks, measuring accessible pine trees with a tape measure, and analyzing
the data. It was determined that in a general sense, the size of pine trees (Pinaceae) at
breast height increased as I measured further into the canyon from Provo. Overall, the
data from the scientific observation showed that the circumference size of pine trees
(Pinaceae) increased and suggested that a certain factor like temperature, elevation, or
interference by man has caused that trend to be apparent.
Key words: Provo Canyon, circumference, Pinaceae, breast height.
Affect of sunshine on avian singing in Provo, UT
Caitlin D. Schille, 3104 Taylor Hall, Provo, UT 84604 Email: caitlinschille@yahoo.com
Abstract:
Through casual observance in my day-to-day life, I began to sense a pattern
concerning a relationship between avian (bird) singing and weather. It seemed that there
was a pattern occurring where I would hear birds singing on sunny mornings, but not on
cloudy mornings. From that I concluded that weather, specifically the appearance of
sunshine, must affect bird singing. I tested this hypothesis. Every morning for twelve
days, I recorded the weather and whether or not I could hear birds singing. After
conducting my test and learning from other scholarly research, I came to the conclusion
that yes, weather does affect avian singing, but there are also other factors that affect it as
well.

Effect of altitude on plant diversity on Y Mountain in Provo, Utah, USA
Brittany Schlosser, 2106 Hinckley Hall, Provo, Utah, 84604 Email:
Bschloss246@gmail.com
Abstract
I conducted this experiment on Y Mountain in Provo, Utah. I observed plant
diversity as I hiked up the mountain to a greater altitude. The purpose was to test the
hypothesis that the higher the altitude, the more the species will decrease in variety and
each remaining species will be more abundant. To demonstrate this, I counted and
compared the number of species at the bottom of the mountain, and at various places
along the mountain’s climb. Special attention was also given to the changing number of
each species as altitude increased. It was determined that plant diversity did indeed have
a negative relationship in regard to altitude.

Effect of light on moisture preferences of Canadian nightcrawlers (Lumbricus sp.) in
Provo, Utah, USA
Paul J. Schmidt, 108 W 2170 N #399, Provo, UT 84604, E-mail: naruto-dbzBELIEVE_IT@hotmail.com
Abstract
I studied the effect that various degrees of light had on the moisture preferences of
Canadian nightcrawlers. I placed ten worms in a box with soil divided into three sections
of varying wetness. I tested three light scenarios: bright light, dim light, and total
darkness. I found that the worms were more likely to bury themselves in the soil when
the light was the brightest, whereas in complete darkness most of the worms had
remained in the middle on top of the semi-wet soil. This experiment resulted in the
finding that, in darkness, earthworms preferred to stay on the surface of semi-moist soil
instead of burying themselves in the soil. In bright light, however, the majority of the
worms retreated inside the soil to escape the light. It can be concluded that light does
affect the moisture preferences of earthworms. However, it is still unclear whether light
is the only factor that contributes to these preferences or if another factor (such as soil
temperature) also has an effect.

How dormancy effects the gambel oak (Quercus gambelii)
Stefani Schramm, 2116 Chipman Hall, Provo Utah, 84604,
Email:stefani.schramm@gmail.com,
Abstract:
I wanted to know what processes trees go through during the winter to keep them
alive even though they look as if they have died. While hiking in Provo Rock Canyon
Trailhead I noticed the Gambel Oak (Quercus gambelii) and decided to break off a piece
of one of its branches. In the next few weeks, I came back and observed this branch and
compared it to the surrounding branches. I discovered that plants go into a state of
dormancy during the winter months which makes them appear dead. I saw how the
branch I broke off dried out while the branches around it began to bud; this budding is the
end stages of dormancy.

The Influence of distance trees are from water with respect to, tree size, bark,
leaves, and insects.
Reece Scurr, 3118 Budge Hall, Provo, Utah 84604 Email: rscurrvball1@gmail.com
Abstract
Plants grow very differently in different environments due to the large amount of
diversity in abiotic factors that affect growth. The purpose of this experiment was to
observe trees and surrounding plants in areas that differ in terms of how much water was
there constantly. I observed an area directly on the Provo River and another area in Rock
Canyon to compare the differences between the trees where some have a river to take
their water from and an area that does not have such an eternally accessible body of water
to use. Many different features of the trees were observed and compared including their
identity, their leaves, what kind of bark they have, what kinds of insects inhabit the
different trees and their respective sizes. I found that at the time I performed the
experiment it was too cold for the insects to be living there and they had moved away or
died. I observed that the Fremont Cottonwood (Populous fremonti) and the American
Linden, or Basswood (Tilia maricana), trees along the river were much taller and thicker
than the mainly maple and oak trees in Rock Canyon and conclude that the much smaller
distance to the river is the primary reason for this larger size (Brough 1993).
Key words: Cottonwood (Populous fremonti), American Linden, Basswood (Tilia

Preference Shown by Birds of Provo for Peppers Varying in Heat Levels
Andrew Serfas, 852 W 2000 N Provo Utah 84604. Email: Andyserfas@gmail.com
Abstract
The behavior of birds is tested when they are given the choice between seed
mixed with various peppers possessing different levels of capsaicin. This will test the
idea that birds are immune to the effects of capsaicin allowing them to eat hot peppers
and spread the seeds. This is done by mixing peppers of different capsaicin levels with
the same amount of birdseed. The birdseed is then placed into feeders in the same
location. After a few days each container is measure to record how much of that mixture
was consumed. Several previous studies were reviewed that deal with pepper
consumption and the distribution of their seeds. When the experiment is completed the
recorded data is analyzed and any trends in pepper preference shown by the birds in
Provo , UT will be discovered.

Affect of precipitation on Gambel Oak (Quercus gambelii) leaf decay in Rock Canyon
Park, Provo, Utah
D. Hunter Shepardson, 2107 May Hall, Provo, Utah 84604
Email:drumtillyadie82@msn.com
ABSTRACT
In the past 3 or 4 months, Utah has had a dryer winter than is typical for the area.
Because of this, leaf decomposition will be affected in one way or another. Living matter
decomposes at a quicker rate in situations that include higher precipitation or humidity
than usual (Poté, Rossé, Rosselli, Tran Van, and Wildi 2005). The effect that these
conditions will have on Gambel Oak (Quercus gambelii) leaf decomposition in Rock
Canyon is unknown. Leaf litter samples will be collected and observed from Rock
Canyon, and compared with similar previous experimental studies done by scientific
experts; doing this will help to determine the validity of the current experiment and how
Gambel Oak leaf decomposition is affected by precipitation in the winter. Leaves will be
collected from different sites (e.g. a ravine, the side of a mountain, by the road, etc.)

Measuring the eating habits of sparrows in Provo, Utah:
Spizella passerina, Zonotrichia leucophrys, Melospiza georgiana
Joel Sherlock, 1080 E 450 N #13, Provo, Utah, 84606 Email: js.sherlock@gmail.com
Abstract:
Experiments were performed in Provo, Utah outside the author’s home. A
birdfeeder was furnished from a simple cardboard box and a wire to bind it to the tree.
Observations were made periodically to see which birds were eating out of the feeder and
how much of the seed was eaten. Originally, the goal was to switch out the bird seed to
see if there would be a change in consumption of bird seed; however, the birds did not
seem to eat any seed at all. In short, the experiment did not work. As the author did
more research on backyard birds, he revealed factors having to do with habitat and
climate being the main obstacles impeding the success of this experiment.

The Functional Similarities and Differences Between the Six Different Species of Pine
Trees Living in Utah
John Sherman, 1123 May Hall, Provo, Utah 84604 Email: jsherman303@gmail.com
Abstract:
Among the six species of pine trees native to Utah, there are several different
varieties of traits and characteristics. These include differences in leaves, twigs/buds,
fruit, and bark. The purpose was to discover a possible explanation for these trait
variations. I went to Mt. Timpanogos to observe each of these species of pine so as to
better understand the trait variations and to hypothesize about their functions. My
expectation was that the differences would affect growth at different altitudes. I came to
find however, that the similarities found in the pines, were far more than the differences.
I believe that these similarities lend themselves to the abilities of these pines to grow in
regions that are cold and dry.

Carbon trapping capabilities of urban trees in one residential block in Provo, Utah
Rachel Sherman, 2093 N 40 W #323, Provo, Utah 84604 Email: rsherman6@gmail.com
Abstract:
Global warming is caused by the presence of greenhouse gases in the atmosphere,
which trap heat and increase the surface temperature. Carbon dioxide emissions are the
most significant human contribution to greenhouse gases in the atmosphere, and the sum
total of carbon dioxide produced by a product is known as a carbon footprint. CO₂
sequestration and storage by trees is an effective way to combat CO₂ emissions.
Sequestration is the process by which trees absorb CO₂ through photosynthesis and store
it as biomass. This project was designed to determine if there was enough carbon stored
by urban trees to counteract one human carbon footprint. Trees growing on a residential
block in Provo were identified and measured for their CO₂ storage capabilities. There
was enough CO₂ storage in these 24 trees to balance one carbon footprint, but there was
not enough storage to counteract the carbon footprints of all the human residents on that
block. Although humans are still producing more CO₂ than the earth can effectively
absorb, trees are still one of the most important and effective ways of counteracting
human carbon dioxide emissions.

Email: tiffany.shotgunn@gmail.com
Abstract. This study was done to discover whether Provo River, Utah Lake or a pond in
Pleasant Grove had more plant diversity. A specific amount of land was searched along
the water’s edge in each specified location to gather data. Pictures were taken at each site
of all unique plants identified along with a photo of the entire area searched. The size and
color of all of the plants were noted and compared in each area. After multiple visits to
each site the data revealed that the river had the most diversity, followed by the lake and
then finally the pond.

AbstractFrom microscopic to viewable life along with abiotic components within a body
of water holds clues in classifying the health of the system as a whole. Variances in life
found in different locations will be studied and conclusions may be drawn from the data.
Samples will be taken along the Provo River, noting elevation and specific environment
at each site. Variance in water temperature and especially benthic substance at each
location will also be recorded, as it may play a role in the biodiversity living at each site.
Outside sources will be matched to new data to help decipher signs of variance and what
the finding could mean.

Abstract: I studied the growth size of three tree species; Gambel’s Oak (Quercus
gambelii), Bigtooth Maple (Acer grandidentatum) and Douglas-fir (Pseudotsuga
menziesii) in Rock Canyon near Provo, UT. Several specimens of each species were
measured for diameter at breast height (dbh), elevation, and estimated height in three
general locations; on the south-facing slope of the canyon, on the canyon bottom near the
stream, and on the north-facing slope. The intent of the study was to determine which
abiotic factors most influence habitat preference for each of the species in question. Both
Q. gambelii and A. grandidentatum showed much larger dbh near the stream than on
either the north or south facing slopes, while P. menziesii showed a greater height-todiameter ratio near the stream, but no noticeable difference in average diameter at the
same location. A much larger distribution of P. menziesii was found on the north-facing
slope than on the south-facing slope, but surprisingly, my data showed that P. menziesii
specimens were smaller on the north-facing slope. Both deciduous trees (A.
grandidentatum and Q. gambelii) were more densely distributed on the south-facing slope
of the canyon, and their distribution seemed consistent with other studies showing these
species to be drought resistant (Ganey & Vojta 2010; Bsoul, St.Hilarie & VanLeeuwen
2007). The data confirms some hypotheses and disproves others, showing that abiotic
factors are not the only variables influencing growth size and distribution of primary
producers in an ecosystem.

Abstract
Cottonwood trees (Populus fremontii) are able to withstand some of the harshest
conditions of the Utah climate; experiencing extremities in availability of water. This
affects their structural composition, as stated from the experiments of Rico Gazal (Gazal
2006). Experiments will be conducted using leaf samples from cottonwood trees
(Populus fremontii) found in Provo Canyon. The structure of such will be identified and
mapped under a microscope to discover the inner workings of the plant and to learn how
the plant manages to sustain life in a harsh, fickle environment. The results from the
experiment signaled no important connection between weather and leaf composition.

emily_blue1015@yahoo.com
Abstract:
Birds in Provo, Utah are often fed from bird feeders put outside by people in local
communities. Their ways to retrieve food and nutrition differs greatly from avian
frugivores. I was curious as to how birds native to Utah would respond to seeds from
different types of fruit. I conducted an experiment to discover whether birds in Rock
Canyon would prefer enriched store bought feed or unfamiliar seeds of various fruits. I
collected twenty seeds from each fruit - tangelos, lemons, kiwi, cantaloupe, and apples. I
selected twenty seeds of 5 different types from “Universal blend” store bought feed. I
placed the seeds in a birdfeeder for 48 hours in Rock Canyon, Provo, Utah, U.S.A. After
retrieving the bird feeder I discovered that more fruit seeds were devoured by birds than
the store bought feed. Although this did not support my hypothesis, I discovered several
reasons as to why this occurred. These reasons include the fact that birds are somewhat
inadequate in nutritionally balancing their diets, the multiple factors that influence what
birds choose to eat, and the background color of the birdfeeder in contrast to the color of
the seeds.

Abstract:
As I walk around the campus at Brigham Young University, I am blessed to be
surrounded by some beautiful parts of nature and creations of this world. Some of the
most abundant and beautiful living beings are the wide variety of trees here in Provo.
This makes me wonder, why are there so many kinds of trees? Also, why can’t every
tree be the same? Why are they so different? Since I lack the resources for an in depth
experiment of the physical characteristics of trees, I made (mostly visible) observations
of the outermost part of the tree: the bark. I studied this topic by taking various photos,
samples and observations of the bark of trees (and by doing lots of research). While this
may seem insignificant, there really is a lot to learn about a tree and its functions by the
characteristics of its bark. Observations were made in Rock Canyon because of the
variety of trees that live there.

Abstract
I went camping last week up Provo Canyon. During my two night visit, I noticed there
were ants everywhere. These weren't the typical ants you find in the city in your front
yard. These ants had much larger bodies and heads and were a dark red. I observed these
little creatures marching in a line to certain destinations unclear to me. I kept thinking
that these ants looked so busy, moving around to and fro. But to where and after what?
There were several other campers around our area. Each camp site had bags of trash out
and cooking supplies left unattended covered in food residue. I began to understand what
these little tricky ants were up to. But with so many choices of what to eat—there were
bags of chips out, raw hot dogs, left over chocolate s'mores sitting around, marshmallows
that had fallen on the dirt. What types of food were these ants really interested in eating?
This question fascinated me and I chose to do my own little research on which certain
types of food the fire ant prefers for feeding. I decided to conduct my own experience
with food choices that I'd concoct using two food compounds that I believed to be readily
available to this specie of ant environment. The two food tests options I created had either
a sucrose-enriched food source or a fat-enriched food source. I mixed bread crumbs with
either sugar or butter to accomplish this. As I hypothesized, my observations showed that
the red ants prefer a food source that is enriched in sucrose over that of fat.

Abstract. Small minnow mayflies are respondent to the temperature fluctuations
corresponding with seasons, and change their behavior throughout the year, but the shortterm effect of abiotic factors has not been extensively researched. I conducted a 4-week
study to measure the correlations between temperature fluctuation and Camelobaetidius
population size. Locations along Hobble Creek in Springville, Utah are selected and
described. Macroinvertebrate specimens are collected, some are identified, and all are
counted. Temperature data is recorded for the investigation period. I observed a
temperature rise towards the middle of March and a fall towards the end, and a sharp
increase then decrease in small minnow mayfly population size over the month. It is
determined that there is a strong correlation between air temperature and the population
size of small minnow mayflies. Egg behavior and temperature-dependent survivability
are isolated as the root of the correlation. When it is warm, their populations increase, and
when it is cold, they decrease.

The Affect Elevation has on the Radial Growth of Cottonwood (Populus deltoids) and
Boxelder Trees (Acer negundo) in Vivian Park, Provo Canyon, Provo, Utah, USA
Kayla Soderberg, 2103 Taylor Hall, Provo, UT 84604 Email: princesskazaar@gmail.com
Abstract:
There are various factors that affect the rate of which trees grow, both in height
and in width. Climate and elevation are major components in the role of tree growth.
For this experiment, I wanted to test my hypothesis that trees gradually got thinner with
an increase of elevation. In order to test this hypothesis, I went to Vivian Park in Provo
Canyon to measure the radial width of two different species of trees at different
elevations. Although my results were unclear, and did not support my hypothesis
because of the mixed results that I received, it is known from previous studies that trees
decrease in size with an increase of elevation. The rate of tree growth and production is
mainly due to the climate in which they grow. Climate consists of two main factors:
temperature and precipitation. Although all trees are affected by both of these influences,
temperature tends to have more of an impact on trees at higher elevations, while
precipitation has a greater influence on trees that are located at lower elevations.

Gold Fish: Memory, Spatial Cognition, and Social Learning
Jaewon Song, 182W 960N Apt. H, Provo, Utah 84604, jaewon.song@yahoo.com, April
2011
Abstract
Although many people think that gold fish have a short term memory, my
experiments show that they actually have at least a 48 hour memory. My experiments
also indicate that gold fish have a capacity of spatial cognition so that they remember
from which way their food comes in. Even though the experiments show that gold fish
don’t remember a complex pattern, they suggest that they are smarter than people have
assumed them to be. It has also been proven that they do social learning from an
observation where one gold fish in an experiment consistently learned from other gold
fish. I conclude that gold fish have at least a 48 hour memory, a capacity of spatial
cognition, and a character of social learning.

Perching birds (Passeriformes) preference for artificially colored red seed in: Utah,
U.S.A.
Paris Sorbonne, Harris Hall 66, Provo, Utah 84604 Email: paris31sorbonne@gmail.com
February 2011
Abstract:
I studied local birds found within suburban foothills of Salt Lake City near
Emigration Canyon. For this experiment I created three different artificially colored seed
choices: blue, red and yellow. Each individually colored seed choice was separated into
two groups and then weighed at 45 g. The first group of seed [B1, R1, Y1] was placed
outside in three separate bowls for perching birds (Passeriformes). The second group [B2,
R2, Y2] was placed in a segregated bird feeder. The purpose of this experiment was to
test my hypothesis that birds will prefer yellow-colored seed 25% more than red and 45%
more than blue seed. After analyzing my experiment data I discovered unexpected
results. In fact, perching birds found in Salt Lake City showed preference to red seed
22% over yellow seed and 54% over blue seed (see table 2). My discussion of the
experimental data collected seeks to attribute this color preference to bird’s unique
ultraviolet sight. My data also suggests that perching birds prefer seed to be placed in
individual bowls rather than segregated on a bird feeder (see table 1 and 2). It was also
noted that perching birds were more inclined to eat the natural prevalence of worms
rather than colored seed during my experiment. For both the worm and bird bowl
findings I offer no explanation.

Abstract
I studied non-migratory birds’ (Aves) eating habits how they varied based on
temperature. The experiment was conducted at Rock Canyon Park in Provo, Utah. I
placed a pan holding 1 cup of bird seed in the park every other day and recorded the
temperature as well as how much bird seed was consumed during my absence. I found
that a greater amount of bird seed had been eaten during times when temperatures
dropped as opposed to days with a higher average temperature. I conclude that there is a
correlation between temperature and the influence it has on birds’ eating habits. I suggest
that the lower the temperature the more food birds will consume in order to survive
during the freezing winters.

Email: rstark7754@gmail.com
Abstract
This experiment was conducted in a nearby park in Orem, Utah. It was done
over a one month span during March. The purpose of this experiment was to study
which trees different species of birds preferred to reside in. I acknowledged the
activities that these different kinds of birds were participating in and how it
corresponded to the tree of choice. In order to distinguish the between the birds I
used a bird identifier and a tree identifier to decide the specie of tree. It was
determined that the main reasons that birds settled in the trees they did is because
of the protection, shelter, and food it offered. Since this research was conducted in
the winter months in Utah the most popular tree that attracted many different
species of birds were the conifers (evergreens, firs, shrubs, and arborvitaes). The
specific birds that were attracted to the different trees seemed to not be as vital as
the kind of tree that housed all the birds.

Effects that living in an environment without mammals or fowls has on Pheidole

astaton7@gmail.com
Abstract:
In an ecosystem animals and plants depend on each other for life and even one species
leaving the ecosystem can have major effects on the rest of life in that ecosystem (Neil,
2,3). Because life depends on other life to survive, all species in an ecosystem suffers
when other species are absent from that ecosystem. Data was collected in an area devoid
of mammals and birds called Pelican Point Utah by measuring four three meter by three
meter plots of ground and counting the amount of ant colonies in each area. Slate
Canyon Park in Provo Utah was the control area to demonstrate what an area with plants
and animals would be like. The point of the experiment is to see whether or not the
removal of large animals from an ecosystem affects the ability of Pheidole pilifera to
survive. My hypothesis is that since there is not much animal life in Pelican Point Utah
the number of ant colonies found there will be less than the amount of ant colonies found

Influence of sugar on food selection made by ants (Hymenoptera: Formicidae)
Michelle M. Steele, 3105 Stover Hall, Provo, Utah 84604 Email: msteele918@gmail.com
Abstract:
I studied the preference that ants (Hymenoptera: Formicidae) have towards
different amounts of sugar in their diets. I set up three different food types near each
other, all the same size but with differing sugar levels. After waiting for the ants to
respond to the smell they started to arrive and be attracted to the sugar. The ants seemed
to be more responsive to the food type containing the highest amount of sugar however
they were still attracted to the others. Distance to food did not seem to make a difference
in this test. Ants want and need for food alone could have caused them to have no
preference at all to the different sugar amounts. Whether did seem to be somewhat of a
factor in this experiment, however the temperatures and/or effects of the whether on the
samples and ants was not recorded in relation to this experiment.

Difference of Snails and Slugs in Characteristics and ActivityCosette Stone, 267 E
500 N Apt. 56, Provo, Utah 84606 Email: cosettestone@gmail.com Submitted April
2011.Abstract:Data and specimens were gathered from Provo, Utah river. The Helix
aspersa (common name: Snail) and Gastropoda pulmona (common name: Slug) were
observed and compared. These common creatures are found and despised in home
gardens everywhere. Both are extremely similar with a slimy body and the long eyes that
extend outwards as they move across rocks and branches. They both act in very similar
ways. For example, they both hide during the daytime or when it is sunny, and come out
at night and when it is dark or cloudy. The purpose of this study was to extensively
observe the two creatures to find other differences other than the obvious shell. I
hypothesized that both creatures stem from the same ancestor and that they evolved into
what they are now which is why they are so similar but have such a significant
characteristic difference. Research was done to gather more information about any
unobservable differences and if the two came from the same species. It was found that the
only observable difference between the Helix aspersa and the Gastropoda pulmona is the
shell that rests on the back of the snail. It was not found whether the two species came
from the same ancestor, but it was found that they both are from the same phylum and are
extremely similar.Keywords: Collect specimen, Helix aspersa, Gastropoda pulmona,

Ecological influence on the intrinsic rate of the cougar population (Felis concolor) in
Rock Canyon and Provo Canyon: Provo, Utah, USA.
Clara Stratford, 984 Dover Dr., Provo, Utah 84602, Email: clara.stratford@byu.net
Abstract:
Despite cougar’s (Felis concolor) habitat having a large range from northern
Canada to the southern Andes, its preferred habitats are in precipitous canyons and dense
brush. Cougar tracking has become increasingly more difficult as more humans take over
the cougar’s habitat. An experiment was conducted by cougar tracking and making note
of cougar tracks and human influence in both Provo Canyon and Rock Canyon. This
experiment determined that the human influence in the canyons surrounding Provo has
caused a decline in area for cougars to live in, and fewer prey for cougars to hunt. These
factors lead to an intrinsic rate of population decrease.
Key words: mountain lion, panther, puma, precipitous canyons, dense brush, cougar

Influence of salt content in the water habitat of Brine Shrimp (Artemia salina)
in the Great Salt Lake, Salt Lake City, Utah, U.S. A.
Mary Stuart, 3221 Stover Hall Provo, Utah 84604, mcstuart101@gmail.com
Abstract
Brine Shrimp (Artemia salina) are an ancient species that live in salty lakes all
over the world, but don’t live in oceans. The salt content in the Great Salt Lake ranges
from 5-27%, but averages about 12%. The salinity of the ocean only averages about
3.5%. This led me to want to know why Brine Shrimp only live in water habitats with
high salt contents. My experiment was held in Provo, Utah using experimental
environments modeled after the original habitat of the Brine Shrimp located at the Great
Salt Lake in Salt Lake City, Utah. A controlled number of Brine Shrimp eggs were
placed in water habitats with differing levels of salinity to see if survival was possible in
saltier or less salty environments than the control, which was the average 12% salinity.
The eggs were watched to validate whether or not they hatched during a seven-day
period. It appears that Brine Shrimp survive better in saltier environments because the
Brine Shrimp in the control and the sample that was twice as salty survived the longest
and had the most hatchlings out of any of the environments.

The Effects of Varying Water Supply on Tree Growth. (Populus Balsamifera)
Michael Thurston, 1281 Locust Lane, Provo, UT 84604, Email: thurmich@byu.net
Abstract:
Observations were taken in Provo Canyon, Utah from various locations. The data
from the observations were recorded from trees of a like species (Populus Balsamifera)
Balsam Poplar (Populus Balsamifera). In order to find causality, three separate locations
were identified, for like requirements, to find conclusions for hypothesis testing. The
Hypothesis of interest is, there are diminishing returns for water inputs for the growth of
plants particularly trees (Balsam Poplar). There are three areas to test the hypothesis, first
area, trees that are close to the river providing abundant supply of water year round.
Second area is a park with a sprinkle a system to control or provide optimal amounts of
water for plants in watering region. Third area is an area removed from the effects of
automatic irrigation and removed from a constant water source such as a river. Results
show trees in the second area that were planted during the same time period as those in
other areas on average have larger diameter for their trunks. I suggest this is due to
diminishing returns from excess water supply and limited water supply for drier areas.

The Effects of Cold Weather upon Mallard Migration
Jessica Lea Turner. 747 North 200 East; Provo, Utah 84606 Email: tantar03@aol.com
Abstract
After finding ducks that did not migrate from the Great Salt Lake, I recorded the
date, time, temperature, and number of Mallard Ducks present at a run-off stream near
the Great Salt Lake for eight weeks in attempt to determine how these birds have adapted
to northern environments during winter months and the factors that limit their winter
distribution. Research shows that Mallards do indeed migrate among numerous corridors,
and are one of the latest among the dabbling ducks to migrate each fall; with only a
modest amount remaining in the Great Salt Lake area through winter.
Key words: waterfowl, Great Salt Lake, migration, Mallard Ducks, climate
Abstract:
The experiment was performed at the Rock Canyon Park in Provo, Utah and
surrounding areas, more specifically foothill area east of the park. Leaves examples were
cut from trees in that area and classified, then each one of them were analyzed and
compared. The importance of the leaf in the process used by each tree to get through
winter was discussed and the number of features presented by them directly related to
winter survival was computed. Three features were observed in a coniferous tree leaf
while only one characteristic of winter adaptation was related to a leaf in the deciduous
tree. Those features are wax around the leaf, resin inside the leaf, and small and needle
shape for the coniferous trees and for the deciduous tree the feature found was a scar
tissue formed where the leaf was attached, that has the function of keeping the water in
the tree.

The Affects of Soil Temperature and Moisture on Vegetation of Y-Mountain in
Comparison to Different Regions, Latitudes, Faces of The Mountain, Elevation, Sunlight,
Ph, and Conductivity of The Soil.
Michael Valentim, 168 F. Smith Hall, Provo, Utah 84604 Email:
rackadisciprine@gmail.com
Abstract
The main question I wanted to answer with my study was “Why certain regions of
Y-mountain seemed to be barren (or filled with seemingly dead vegetation), and others
seemed to almost flourish with life?” To do so I had to focus on only a few identifiable
plants on Y-mountain which included the desert hackberry (Celtis spinosa), the seep
willow (Baccharis salicifolia), and the big sage brush (artemisia tridentate). Then
according to where the plants were I recorded the different aspects of the soil including
temperature, ph, sunlight concentration throughout the day, elevation, and the gps
coordinates. I hypothesized that there had to be some sort of water source near these
“greener” areas. I found that near ridges and crevices, where there was a partial shadow
on vegetation throughout the day, moisture was conserved in the soil. Upon hiking to a
higher elevation I found that the moisture came from the melting snow on the top of the
mountain, which would then be guided down onto this ridge. The resulting ph of the soil
resulted from the minerals that were carried off, and eroded from top of the mountain and
descended down along the mountain ridge. Which gave this soil more nutrients and
allowed its plants to readily flourish. Showing that certain regions of Y-Mountain are
more productive than others based on their proximity to water.
A controlled experiment and explanation of how weather and climate affect the
migration of birds (CHORDATA aves) native to Utah

jazzie@acaydia.com
Abstract:
It is often said that CHORDATA aves, more commonly known as birds, fly south
to warmer biomes when the weather is cold in their indigenous home. With the current
fluctuations in Utah County’s weather, I was intrigued to research what birds were still
flying south if any at all. My hypothesis was that birds would still continue to fly south,
and that these CHORDATA aves would be more likely to travel on days of colder climate.
To analyze this theory, I went to a set location (Bicentennial Park, Provo, Utah) every
seven days and observed the flights of the avian population for eight weeks. The
temperatures and weather conditions fluctuated heavily, and after collecting my data in
my field notebook, I reviewed my findings. I came to the conclusion that certain birds
native to Utah are more likely to fly south on days that temperatures were above the
freezing temperature of thirty-two degrees Fahrenheit (zero degrees Celsius). I believe
that this is because birds, being warm-blooded creatures, are aware of their environmental
temperatures.
Key words: migratory patterns, flight, temperature, climate, CHORDATA aves.
Affect of Runoff Water on Insect Diversity in Provo River, Provo, UT
Danielle Viehweg, 60 Harris Hall, Provo, UT 84604 Email: danielle.7007@gmail.com.
Submitted April 2011.
Abstract:
I studied the effects of runoff water from streets on the invertebrate diversity in
the Provo River in Provo, Utah. Two samples of approximately 50 bugs were taken from
three different sites along the river going from an area directly under a storm drain in the
center of town to the mouth of the canyon from which the river flows in a more rural
area. The deeper I got into the city, the less diversity I found in the invertebrates which I
collected. In more urban areas there is a greater amount of pollution being picked up by
the river which decreases the chance of extreme biodiversity in the river. Pollution is
killing important invertebrates in the ecosystems of the rivers which we need and enjoy.

Affect of Weather Conditions on the Appearance of Sunsets: Provo, Utah, U.S.A.
Heather Virgo, 3113 Taylor Hall, Provo, Utah 84604 Email: heather.virgo@hotmail.com
Abstract
The appearance of sunsets is continually changing, and one could go so far as to
say that there are never two that look exactly alike, but more research is required before I
can decide if the weather conditions and temperature affect the overall color and
appearance of the sunsets. Experiments will be conducted by observing the sunsets from
Rock Canyon, once a week on the same day, at the time that the sun has been predicted to
set. I will record the times that the sun was supposed to set, what time I observed the
sunset, the temperature, visibility, humidity, and what the colors were and how bright, on
a scale of 1-3.

Elevation effects on the circumference of trees (Populus tremuloides, Quercus gambelii,
Acer negundo)
Kristine Wait, 2223 Taylor Hall, Provo Utah 84604. EMAIL: kristine2413@hotmail.com
ABSTRACT:
Tests and research was conducted in Provo City, Utah County, Utah. Different
trees (Populus tremuloides, Quercus gambelii, Acer negundo) were measured for their
circumference. Taking into consideration average height, the measurements were noted
along with the elevations at which the trees were located. The purpose of this research
was to test the hypothesis that tree trunk circumferences would be greater at higher
elevations. It would be wise to note that factors such as natural soil, more sunlight, and a
biologically friendly environment, were taken into consideration when constructing this
hypothesis. Due to the assumption that these biotic factors varied based on elevation, they
would therefore influence the measurement of tree trunk circumference as well. In March
2011 the three different types of trees selected, at three different elevations, were studied
and their measurements were found to contradict this hypothesis. All three-tree types,
regardless of heights specifically relative to each species, had decreasing circumference
measurements as elevation level rose.

Abstract:
The giant black sea bass, garibaldi, and bocaccio fish are all found in various
areas along the coast of California and especially the Southern areas. These fish are all
highly endangered but each is very different. It is my goal to research them and discover
aspects of their behavior and characteristics that aid in the reason for their endangerment.
I will observe them in local aquariums and draw conclusions for myself. I will also be
surveying people to discover how much they know about these fish, and draw
conclusions on the effectiveness of protection and awareness of these fish, their
endangerment, and their conservation.

lisadawn45@gmail.com
Abstract
The Giant Sea Bass, garibaldi, and bocaccio are all endangered fish that can be
found along the southern Californian coast. (cite) Causes for these endangered fish are
over fishing, habitat loss, and pollution. (thinkquest.org) Because these causes come from
humans, it is important to try to understand people’s knowledge about these fish and what
they are willing to do to help the species. With permission for this study, surveys of 45
people were taken in the Santa Monica Pier Aquarium in Santa Monica, California.
Surveys were conducted at the end of February 2011. Questions were asked concerning
whether or not the person knew about each of the above mentioned fish, organizations
that protect those fish, and if they were willing to help in protecting them. The surveys
were evaluated to compare gender, age, and the residency of the people and if those
factors made a difference. I predicted that less than 25% of the people would know that
these fish were endangered but despite that they would still be willing to help protect the
species.

Response of Birds to Simulated Bird Calls in Bountiful and Farmington, Utah, USA
Rebekah Wilbur, 56 Horne Hall, Provo, Utah 64604 Email: whitedaisies13@hotmail.com
Abstract:
Birds communicate with each other through the unique and distinctive sounds that
they make, but will they respond to simulated sounds emitted from a recording?
Experiments will be conducted in Bountiful, Utah and in the Farmington Bay Bird
Refuge to determine whether or not birds will reply to a computer-generated sound. By
using a speaker to emit the recorded bird calls, birds that reply and birds that do not reply
will be identified and recorded. Each simulated bird call will be repeated ten times in
order to give each bird an opportunity to hear the sound and reply to it.

Abstract
There are many influential factors that contribute to the growth rate of algae in
rivers. Such as dissolved Carbon Dioxide levels, acidity levels, and sunlight. However, I
wanted to focus on the aspect of water depth and its influence on algae growth. I believed
that water depth played a big toll on algae’s ability to grow. I thought that the Provo
River would be a great place to conduct my experiments. To start off I purchased five
tiles from Lows that were about one square foot each and dispersed them along the river
at various depths. I would then check every three to four days to examine and record
algae growth. I would then try to determine which species of algae were growing more
prevalent at each depth. I would continue this experiment for a month to collect enough
algae to report on.
Key Words: Algae, Water Depth, Dissolved Carbon Dioxide
Thermal Effects on the germination of beans around Taylor Hall: Provo, Utah, U.S.A.
Wilson, Eliza Marie, 2212 Taylor Hall Provo Utah, 84604 Email: emw511@hotmail.com
Abstract
When reflecting back on elementary science fair projects, I remembered one
specifically that caught my attention: the germinating of pinto beans. I started wondering
what would have happened if I expanded my testing. What if the beans were soaking in
water? What if they were suspended above water? Does temperature pay a special part in
their growth? I got three jars; each containing a soaked pinto bean. I had week testing the
constant variables which then was followed by two weeks of testing groups. Each of the
three jars germinates at room temperature. Then the next week I left one jar at room
temperature, one jar buried underground, and the other jar hidden in a bush. I repeated
that process for two weeks. I measured the temperature every day and then saw which
beans had grown and germinated the most after a process of three weeks to see how they
reacted to their different temperature environments.

Temperature and Mule Deer Migratory Habits
Abstract
The Odocoileus hemionus, more commonly known as the Mule deer, tend to live
in the mountains away from civilization during the spring, summer, and fall months. I
predict that during the winter, when the temperatures drop below freezing, the Mule deer
will come down from the mountains and sleep closer to society. I believe that the colder
the night, the farther down the mule deer will rest. I believe they do this in order to
escape the harsh winds and low temperatures at the top of the mountains and venture into
the valley in order to get warmer temperatures. To test this hypothesis, I will go out on
seven different nights with seven different temperatures in search of the Mule deer. When
I find the deer, I will record the location and the temperature that night. After completing
this exercise, I discovered that my hypothesis was correct. When it was 35 degrees or
warmer, the deer stayed in the mountains. However, once it was around 25 degrees they
began to venture farther out into society.

An investigation of the correlation of brown trout (salmo trutta morpha lacustris) activity
and water flow levels in the lower Provo River.
Stephen I Wong, 2210 Budge Hall, Provo, UT 84604 Email: st.wong13@gmail.com
Abstract:
Experiments for this study were conducted in the Provo River, in Provo Utah.
Samples of Brown trout (salmo trutta morpha lacustris) were taken from the lower Provo
River using two types of artificial flies. Water flow rates were taken from provisional
data and then compared to the days that fish were caught on to establish a correlation.
The number of fish that were caught on a given day were compared to the water flow
rates (measured in cubic feet per second) which indicated the “activity” of the fish on that
day. From this study, a correlation was indeed established between the flow rate and the
activity of the fish in the river.

Abstract:
I identified three different sets of Snowshoe Hare tracks up Little Cottonwood
Canyon through the months of January to March 2011. Here I identified the tracks,
observed the habitat, took note of the weather conditions and documented the coniferous
trees found within approximately 2 meters of the tracks. I discovered that Snowshoe
Hares do not come out when it is snowing, bitter cold, or cloudy, but instead, tracks are
most easily found on a sunny day after a storm. The tracks are found moving in direct
paths through coniferous trees mainly including Douglas Fir (Pseudotsuga taxifolia) and
Colorado Blue Spruce (Picea pauryana). They use trees as a source of protection from
predators and food during the winter months. When it is stormy, cloudy, or too cold, the
Hares do not come out in order to stay warmer through the winter months.

Thermal influence in deer (Odocoileus hemionus) activity in urban society
Brandon J. Zepeda, 700 North 460 East #7, Provo, UT 84602, Email: bzepeda@live.com
Abstract
Deer are often seen in urban communities. And although it may be pleasant for
some to see, they can have a negative effect on urban residents. My study was centered
on a way to predict their activity in urban society according to temperature so that
residence might prepare for them. My hypothesis was that at lower temperatures there
would be greater activity in urban areas. I observed an urban area of Provo, Utah for deer
activity according to the temperature of the air. I walked a previously studied route for
several days and I witnessed almost no deer activity. According to my data there is not a
relationship between deer activity in urban area and temperature within a ten degree
range.

Affect of Soil pH on Tree Growth in Rock Canyon, Provo, Utah.
Scott Zobrist, 1117 Budge Hall, Provo, Utah 84604 Email: scottzobrist@gmail.com
Abstract
Experiments were conducted in Rock Canyon of Provo, Utah. The purpose of
this study is to determine to what extent soil pH levels play a factor in promoting or
hindering the growth of trees. For each site I collected soil samples from an area of
prominent tree growth and an adjacent area of barren land. I collected samples from 3
different sites throughout Rock Canyon for a total of 6 samples. The findings were
mostly as hypothesized: soil pH levels of tree growth areas in Rock Canyon are
significantly more neutral than surrounding barren areas. Tree growth is aided by neutral
pH levels but also produces decomposable elements that maintain this neutrality. Water
availability plays a much larger factor in tree growth than pH levels, however. The tree
species tested include the white oak (Quercus alba), the box elder (Acer negundo), and
the white willow (Salix alba).
