Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]
You can find them in the tundras and forests of Canada and Alaska. Northernmost states in the U.S. (such as Idaho and Washington) occasionally see a small herd of fewer than 100 animals.
