Taiga or tayga (/ ˈ t aɪ ɡ ə / TY-gə; Russian: тайга́, IPA:), also known as boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest is the world's largest land biome. [1]
The taiga is inhabited by many species, some of which are endangered, and include the Canadian lynx, gray wolf, and grizzly bear. The Canadian lynx is one well-known animal to inhabit the North American taiga region and is listed as threatened in the U.S. The mother lynx will have a litter of about 4 kittens in the spring.
Animals that are active in the winter have adaptations for surviving the intense cold. [55] A common example is the presence of strikingly large feet in proportion to body weight. These act like snowshoes and can be found on animals like the snowshoe hare and caribou.
Some ornithologists (including AOU 2007) split them into two species based on breeding habitat, whether in forest bogs in the subarctic taiga, or on the arctic tundra. The taiga and tundra bean goose diverged about 2.5 million years ago and established secondary contact ca. 60,000 years ago, resulting in extensive gene flow. [5]
The Alaska moose (Alces alces gigas), or Alaskan moose in Alaska, or giant moose and Yukon moose in Canada, is a subspecies of moose that ranges from Alaska to western Yukon. The Alaska moose is the largest subspecies of moose. [1] Alaska moose inhabit boreal forests and mixed deciduous forests throughout most of Alaska and most of Western ...
The animal life of the reserve is typical of the Mid-Urals taiga: moose, wolf, bear, rabbit, beaver, marten, ermine, weasel, shrews and other rodents. Scientists on the reserve have recorded 48 species of mammals. [1] 185 species of birds have been recorded, of which 125 are nesting. [8]
An Alpine chough in flight at 3,900 m (12,800 ft). Organisms can live at high altitude, either on land, in water, or while flying.Decreased oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes.
For forests, canopy refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, arboreal animals, etc.). The canopy level is the third level of the temperate rainforest. The trees forming the canopy, conifers, can stand as tall as 100 metres or more. A variety of species ...
