Species in the taiga include Alaska blackfish, northern pike, walleye, longnose sucker, white sucker, various species of cisco, lake whitefish, round whitefish, pygmy whitefish, Arctic lamprey, various grayling species, brook trout (including sea-run brook trout in the Hudson Bay area), chum salmon, Siberian taimen, lenok and lake chub.
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 species within boreal ecosystems varies as it consists of both terrestrial and aquatic habitats. The species composition include many generalized and less specialized feeders. [ 4 ] From the equator to the poles, species richness decreases, and there is a negative relationship with species richness changes as climate changes.
The Scandinavian and Russian taiga is an ecoregion within the taiga and boreal forests biome as defined by the WWF classification (ecoregion PA0608). [1] It is situated in Northern Europe between tundra in the north and temperate mixed forests in the south and occupies about 2,156,900 km 2 (832,800 sq mi) in Norway, Sweden, Finland and the northern part of European Russia, being the largest ...
This vast ecoregion is located in the heart of Siberia, stretching over 20° of latitude and 50° of longitude [1] (52° to 72° N, and 80° to 130° E). The climate in the East Siberian taiga is subarctic (the trees growing there are coniferous and deciduous) and displays high continentality, with extremes ranging from 40 °C (104 °F) to −65 °C (−85 °F) and possibly lower.
The taiga vole's habitat stretches from northwestern Canada to Alaska. [3] Fossils have been found as far south as Arkansas, Tennessee and Virginia, suggesting that the taiga voles cover a much smaller range now than in the past. [3] Taiga vole fossils have been found south of where the Laurentide Ice Sheet once was during the late Pleistocene. [4]
Few species of boreal wildlife are classified under government conservation regimes as being at risk of extinction. However, the decline of some major species of wildlife is a concern. Boreal woodland caribou , whose lichen-rich, mature forest habitat spans the boreal forest from the Northwest Territories to Labrador , is designated as a ...
Because the environment is harsh and there are no mountain refuges in the ecoregion, biodiversity in plants is low. Five tree species dominate: the three 'dark taiga' species (Picea obovata (Siberian spruce), Abies sibirica (Siberian fir), Pinus sibirica (Siberian pine)), and P. sylvestris (Scots pine) and Larix sibirica (Siberian larch).
