Transcript of The Siberian Tundra Ecosystem

Siberian Tundra
I am doing my research and project on the Siberian Tundra, which is located in the northeastern part of Russia (between 60 to 80 degrees North latitude, and 70 to 180 degrees East longitude, to be exact). The Siberian Tundra's temperature is usually very chilly. It can be as low as -40 degrees Celsius! Precipitation is low at only 6 to 10 inches per year, including melted snow. The tundra is also very windy, with wind speeds from 30 to 60 mph. As you can see, the Siberian tundra's organisms must adapt to fit the extreme conditions.
Living and Non-Living Factors
Non-Living

strong winds
little precipitation
short days
long, cold winters
poor soil
permafrost
coal
natural gas
zinc
Siberian Tundra Climate
no warmer than 50 degrees Fahrenheit
sun shines almost 24 hours a day
summers only 6-10 weeks
icy climate
Limiting Factors
In the Siberian Tundra, certain factors may limit the amount of living organisms in that ecosystem such as:

humans drilling for oil- oil may harm plants and animals
a plant called permacrest is very poisonous, so whenever animals eat it, they get sick and die
chilly temperatures, high wind speeds, and little precipitation may affect plant growth, hence affecting the whole food web.

Population of White Cranes in the Siberian Tundra Ecosystem
The Siberian White Crane is currently an endangered species, and there are only about 2,900 left in Northeastern Russia (Siberian Tundra)
Fun Facts
The Siberian Tundra has plenty of resources
World War II was partially fought there
Only about 1,700 different species

Arctic Hare Adaptations
Thick, white fur helps insulate body heat and serves as camouflage against the snow (in winter).
Short, stubby ears don't catch cold drafts.
In the summer, their fur changes to blue-gray or light brown in approximation of rocks and vegetation.
Arctic Willow Adaptations
Tree grows low to the ground to avoid wind.
Shallow roots adapted from permafrost.
Willow forms a sort of pesticide to keep away predators.
Tundra Life Cycles 1/4
Snowy Owl
eggs
owlet
-fuzzy, soft feathers, tiny size
mature owlet
-more feathers, pattern, larger, skinnier physique
adult snowy owl
-can reproduce, larger, more feathers, longer wings, stronger
Tundra Life Cycles 2/4
Foxberry
berry pit underground
tiny sprout
mature plant
-grows more berries and flowers
larger shoot
Tundra Life Cycles 3/4
Black Fly (complete metamorphosis)
eggs laid underwater
larvae born aquatically
attach to ground in pupa form
adult emerges from a slit in the pupa case and floats upward
Tundra Life Cycles 4/4
Grasshopper (Incomplete Metamorphosis)
lays 15 to 150 eggs
egg
nymph
-looks like miniature adult, doesn't have wings yet
adult
-can reproduce, has wings, and is larger
