It lives in groups known as packs which are led by an alpha pair. Forbs and other non-grasses and shoots of birches and willows form the primary diet of these herbivores. Keystone Species: In some food webs, there is one critical "keystone species" upon which the entire system depends. The species breeds in the taiga and migrates south in colder weather, usually only going as far as the taigas edge. For example, a food chain is like fish eats algae, shark eats fish and humans eat shark. communities survival factors and species distribution outline how distribution of species is affected limiting factors in ecology, limiting Like many members of this family, the American marten is entirely opportunistic, feeding on pretty much whatever it wants whenever it is available. While beavers are considered to be pests by some, scientists actually have proven that beavers are a "Keystone" species in North America. Boreal forests can be found in the far north of North America, Scandinavia, Russia, and Asia and limited in their diversity of flora and fauna because of the harsh climate.

While foxes, wolves, bears, species of lynx, moose, caribou, beaver, deer, and reindeer are among common mammals adapted to live in the extremely cold temperature of . This exposes the bedrock and permafrost beneath the taiga, which does not support many forms of life.Climate change puts taigas in danger in different ways. The wolverine is the largest land-dwelling member of the weasel family, Mustelidae (the sea otter is the heaviest, but spends most of its life in the sea). This tiny frog species is native to central Canada and makes its home not only in taiga but further north in the tundra, too. Although primarily a scavenger, the wolverine is known for its strength and ferocity. In the spring this process is reversed. However, intense conservation efforts helped revive the population of the American marten. These snakes hibernate during the winter to avoid death in the harsh environment. By building dams across rivers and streams to provide protection and a source of food for themselves, they create wetlands which are important habitats for other taiga animals.

Many trees in the forest-tundra zone have never been known to produce viable seeds or have done so only sporadically. What forest biome has the most amount of land protected? The taiga, which is also known as the boreal (meaning northern) forest region, occupies about 17 percent of Earths land surface area in a circumpolar belt of the far Northern Hemisphere. Because so much of Earths water was bound up in ice at this time, sea levels were lower than they are today, and this allowed migrations of various terrestrial species to occur. A keystone species is a species which has a disproportionately large effect on its natural environment relative to its abundance, a concept introduced in 1969 by the zoologist Robert T. Paine.Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various .
