The TundraBy: Yubin Shin

Abiotic and Biotic FactorsThe tundra temperature is F. The Tundra’s soil is frozen and very thick permanently frozen 10 inches to 3 feet (25 to 100 cm) down so that trees can't grow there (no trees only small plants or moss/grasses) There is no rain. The sunlight temperature can get up to 54° F (12° C), but it can get as cold as 37° F (3° C). Average summer temperatures range from 37° to 60°F (3° to 16°C). There is almost 24 hours of sunlight. The abiotic things gets affected for example snow is abiotic thing in the tundra. The snow doesn't melt even though there is almost 24 hours of sunlight, the snow doesn't melt so that the animals need to survive. In the tundra, there are lemmings, arctic hare, and musk ox and some of the producers are caribou moss and lichens.

Tundra Map

The Tundra is located in Canada, Alaska, bottom of Greenland, top of Russia and tiny bit in the north pole.

Tundra ProducersThe tundra producers are caribou moss, grasses, lichens, and liverworts. They can live in this kind of biome because they don't have roots, they grow on logs or trees.

LICHEN LIVERWORTS GRASSES CARIBOU MOSS

Tundra Animals Caribou: caribou have a compact, stocky body with a short tail and ears to avoid losing body heat. Their skinny legs have veins and arteries that run side by side, so that the heat of the arterial blood coming from the body warms the cooler venous blood returning from the lower legs. Their noses have a special chamber for holding heat and moisture from their exhaled breath to warn the incoming icy Arctic air before it can chill their lungs. They eat mushrooms, grasses, and caribou moss. Caribou get eaten by arctic wolves only. Their broad, concave hoofs spread to aid walking on soft ground and are good for digging in snow. Both sexes grow antlers that in males serve as sexual ornaments and weapons for fighting rivals during the breeding season.

Pika: Pika adaptations are that they are small that they can hide in small places where predators can't go in because it is too small. It also is fast like a mouse that it can run away from predators. Pika eats grasses, lichen, and caribou moss. It gets eaten by arctic foxes and brown bears. They are sort of relatives to hamsters.

Conservation Issues

Alaska is very active with toxics. It also releases harmful chemicals from factories (industry) and military. Also the alaskan people are hunting a lot of tundra animals for fur clothes and meat (food). Also global warming is changing the temperature in the tundra which will affect the animals in the tundra because their body temperature will not regulate with the hotness. People are also catching salmon which is the brown bears food.
