Since the tundra has such a harsh environment, the animals who live here have adapted in a way to call the tundra their home. The keystone species of the tundra can be as small as a lemming to as large as a musk ox. The low biodiversity means that fluctuation in individual animals can substantially affect the entire ecosystem.
