  1. Arctic Tundra By Joseph A. Morgan

  2. Location • The arctic tundra is almost entirely in the Northern Hemisphere. • The arctic tundra is on isolated islands near Antarctica in the Southern Hemisphere. • It falls between two other major biomes, the ice caps and taiga • Arctic Tundra

  3. Climate • The arctic tundra has two seasons: winter and summer. • The sun is usually up for close to 24 hours a day, but only warms up to 3-12°C. • On days where the sun is not up for weeks, the temperature lowers to -28°C to -70°C. • If it is warm enough, trees are able to send their roots deep enough to live and grow. • The precipitation averages at about 6 to 10 inches a year.

  4. Animals • The arctic tundra has about 1700 different species of plants. • There are almost no reptiles or amphibians. • There are only 48 land mammals living there. • Some of the animals are voles, lemmings, the snowy owl, musk ox, seals, and polarbears

  6. Musk Oxen • The musk ox is a part of the Bovidae family. • They are known for its thick coat and strong odor. • Related to sheep and goats more than an oxen. • They live in herds of 12-24 in winter and 8-20 in summer. • The mating season is around June and July. • The babies(Cows) learn how to walk and run in only a few hours. • Cows feed on milk for the first two months and eats plants instead. • The musk ox population was declining from over hunting, so many places have tried to keep them alive in parks, and now they are coming back so we shouldn’t be worried too much. • It’s adaptations are it’s thick coat and horns. • They eat grass, mosses, Arctic flowers, willow, and bark.

  7. Polar Bear • The polar bear is the world’s largest land carnivore and bear. • They weigh about 770-1500 lbs, and the female is about half it’s size. • It’s adaptation is it’s camouflage, black skin for absorbing heat, warm feet for melting snow so it can walk. • Seals make up it’s main diet • A polar bear catches a seal by waiting for one to pop up for air, the polar bear sits on it’s belly and covers it’s nose to blend with the snow. • At mating season, male polar bears fight each other for the female to mate with. These fights may result in death. • The babies(cubs) look a lot like there parents except when they are just born. • The mother bear watches and takes care of the cubs for about two years. She teaches them how to defend themselves and find food. • Male polar bears are always hungry and will always eat other cubs or their own, but the mother tries to defend her cubs even if she dies trying. • Polar bears might try to recognize each other with the smell of urine. • We should be concerned about the polar bear since it’s dying from global warming.
