  1. Tundra Biome

  2. Where is the Tundra located? Located at latitudes 55° to 70° North The tundra is located in the northern hemisphere.

  3. Climate • Moderating ocean winds keep the temperatures from being as severe as interior regions. • The tundra is the world’s coldest and driest biomes. • The annual temperature is 18°F The tilt of the Earth causes the sun’s rays to inefficiently reach the tundra making sub-zero temperatures. • In the winter, the temperatures can drop -70°F • Average summer temperatures range from 37°F to 50°F • The arctic tundra is also a windy place and winds can blow between 30 and 60 miles per hour. • In the tundra, the winter season is very long and severe. • Temperatures can range from • -10°F to 40°F. • A short mild season exists but not a true summer. • The sun’s rays cannot warm tundra area efficiently.

  4. Species of Animals • Although there isn’t a lot biodiversity, only 48 species of land mammals are found in the tundra. • Some of these species consist of hare, rodents, wolves, foxes, bears and deer. • Wolves, Arctic foxes and polar bears are the main predators in the Tundra.

  5. (MustelaErminea) Ermine Ermines live in Canada, Northern USA, and Eurasia. Their diets consists of: Mice, squirrels, carrion (leftover meat) and berries The ermine is a carnivore and eats rabbits, small insects and rodents.

  6. Polar Bears (Ursusmaritimus) Their diet consists of berries and plants, fish, seabirds, and seals Polar bears live in Denmark, Norway, Russia, USA (Alaska) and Canada

  7. Adaptations • When the ground is snowy, Ermines will hunt entirely underground. • They have large teeth to eat animals larger than it. • Ermines’ front feet are smaller than its back feet in order to fit into small places • The polar bear is an omnivore. • It has large furry feet and sharp, short claws that give the bear good traction on ice, • It’s sharp claws lets the bear burrow under the ice sheets to be able to hunt for seals.
