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]
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]
Taiga (boreal forests) has amazing natural resources that are being exploited by humans. Human activities have a huge effect on the taiga ecoregions mainly through extensive logging, natural gas extraction, and mine-fracking. This results in the loss of habitat and increases the rate of deforestation.
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]
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]
[2] [94] In northeastern Norway, it was found that moose were the most important single food item (present in up to 45% of scats and locally comprising more than 70% of the bear's dietary energy) for local brown bears and several local bears appear to be specialized moose hunters, most often picking off sickly yearling moose and pregnant but ...
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
