About The Alpine Tundra.
Biome Location
Average Season Temps
Annual Rainfall
Alpine Tundras are

elevations atop
mountains.
Winter:-34℃/-29.2℉
Only 10 inches
Seasons
Weather Events
Winter last from
October to May
Wildfires and
Droughts
Summer last from
June to September
Summer:3-12℃/37-54℉

Plants that
live in the
Alpine Tundra!
This is where you section ends. Duplicate this set of slides as many times you need to go over all your sections.
13
Cushion Plant
Where does it live:Rapidly draining rocky
or sandy soils
Production or Purpose:The cushion plant
creates viable living spaces for other
species

intertidal zones to the tops of mountains
Production or Purpose: They produce spores
for reproduction, they also serve as
forage, shelter, and building materials
for animals to use.

Bacteria in
the
Alpine Tundra!
This is where you section ends. Duplicate this set of slides as many times you need to go over all your sections.
22
Acidobacteria
Found in: soil, decomposing trees,
hotsprings, caves
What do they for the environment: They
degrade bacteria various carbon sources,
then return carbon to environment.
23
Abiotic Factors
Cold Temperatures
The temperatures are so cold that there is a layer of permanently frozen ground
below the surface.
Limited Precipitation
Tundra regions typically get less than 25 centimeters (10 inches) of precipitation
annually, which means these areas are also considered deserts.
Permafrost
In summer, it traps a layer of water close to the surface, keeping many tundra soils soggy. It
cools the soil and the roots of tundra plants, slowing decomposition and growth. Its presence
influences freeze-thaw cycles, forming unique tundra landforms.
Strong Winds
Winds that average 8 to 16 km (5 to 10 miles)
Sunny Landscape
Along with harsh winds and harsh temperature the sunlight is equally as harsh
24
A Keystone Species
Arctic Fox
A species on which other species in an
ecosystem largely depend, such that if
it were removed the ecosystem would
change drastically.
By this definition an Arctic Fox is a
keystone species because it maintains
the health and prevents the collapse of
the environment, they hunt the species
that might have a chance to over
populate and make the ecosystem crash.
25
Arctic Mosquito
problem
Parasite-A type of organism that
feeds on the nutrient or use the
bodies/larvae of other organism to
reproduce.
The mosquito latches onto animals
and sucks their blood for nutrients
26
Mutualism in the Alpine Tundra
Lichen-Fungi and Algae
Mutualism-Interaction between species
where they benefit from each other.
The two organisms involved are fungi and
algae, the algae provides “food” for the
fungi, the fungi absorbs minerals,
water, and provides shelter for the
algae.
27
Commensalism in the Alpine Tundra
Reindeer and Arctic Fox
Commensalism- An interaction between two
organism and only one benefits and the
other is unharmed.
The two organism involved are the
Reindeer and Arctic Fox,while digging
the Arctic Foxes end up stirring the
soil, and kicking up lichen and grass
hidden under snow, exposing it for the
reindeer to eat.
28
Invasive Species in the Alpine Tundra
Red Fox
The red fox has and is threatening the
entirety of the Alpine Tundra by
competing and killing Arctic Foxes, this
is bad because Arctic Foxes are keystone
species.
How they were introduced is unknown.
They are in direct contact with Arctic
Foxes, where they compete and hunt them.
29
The Importance of the Alpine Tundra
Freshwater
Carbon Sink
It serves as an
important
freshwater
reservoir, even
though it’s
considered a
desert.
Because of the
permafrost, a lot
of carbon is
withheld by the
permafrost
preventing it from
escaping into the
atmosphere.
