Method
-
We conducted and collected the experiment into 9 streams and those streams
are the intermediate streams Porter , Broken and Andrews, the stable Slip
spring , grasmere, and rayban and disturbed dry , Cass and ribbon wood.
To be able to conduct the experiment before we start the data collection we
made sure to have all the gear we needed such as 2 kick nets that is use to
collect the macro-invertebrates and assisting the community diversity in each
streams, we use plastic trays to place the sediments collected from kick netting
which mainly preventing the samples from washing away and used to sort the
macro-invertebrates we collected from our samples as it provide flat surface for
convenience, furthermore, we used 20 big sample pottles to place our samples
and the excess are to made sure we have enough containers, we also need
waders to prevent us from getting wet as we collected the samples from
freshwater streams, we also use paper labels, pen and pencils to write the date
of collection, time , location and our group number. Additionally, we use one jug
of ethanol for preserving of the specimens and organisms stable or being
damaged due to transportation to the laboratory, we also use the Dissolve
Oxygen and conductivity probe to measure the water chemistry sampling such
dissolve oxygen , conductivity , pH , and temperature, To measure the we need
to place both equipment or electrode into the water sample and wait for a few
minutes to stabilize the readings. We also use Pfaunch sampling to observe the
streams disturbance and the other factors.
After we collected all the data on the field we proceed to the lab to analyze out
samples, we use the __ technique to separate larger debris from fine sediments
to easy to see and identify the macroinvertebrates, afterwards, we conducted
subsampling whereas we divided the tray into eight and count the organisms in
one section and identify them then afterwards we multiply it by 8 to estimate the
total of the microinvertebrates in the entire tray or streams it was collected. After
we collected all the data of macroinvertebrates in each of the 9 streams and
calculated the average of the Pfaunch data we place all the data into the excel
file and conducted an analysis into the R studio.

The 9 streams minimum where we collected the data are Porter pass , slip
spring , dry stream , Broken stream, Grasmere stream , Cass stream, the
Andrew’s stream, the rayban stream, the ribbonwood stream.
To be We use the conductivity probe , 2x kicknet , the 4x plastic trays , 20x Big
sample pottles , 3x sets of waders , paper labels, pencils, pens to write on the
plastic containers for the date collected the samples, location , time and the
group number/ members, 1 jug of ethanol , 3x clipboards , 2x rulers ( 1m ), 2x
tape measures and Dissolve oxygen probe to measure the DO and the
conductivity. We use the Pfaunch to observe the streams disturbance and the
other factors.
that could able to explain the patterns within the streams disturbance level.
We mainly focus on the species distribution/ richness across the streams so we
conducted the kicknet.
We are trying to measure the streams intermediate ( Porter , Broken and
Andrews), the stable (Slip spring , grasmere, and rayban ) and disturbed ( dry ,
Cass and ribbon wood ).
To be able to measure the interaction between disturbance and productivity to
modulate macroinvertebrates diversity in streams we conducted the kicknets.
