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 ...
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.
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.
Beaver, Canadian lynx, bobcat, wolverine, and snowshoe hare are all keystone species in the taiga area. These species are keystone because they have learned to adapt to the cold climate of the area and are able to survive year-round. These species survive year-round in taiga by changing fur color and growing extra fur.
Ixodes persulcatus, the taiga tick, is a species of hard-bodied tick distributed from Europe through central and northern Asia to the People's Republic of China and Japan. [1] The sexual dimorphism of the species is marked, the male being much smaller than the female. [ 2 ]
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).

Terrestrial ecosystems occupy 55,660,000 mi 2 (144,150,000 km 2), or 28.26% of Earth's surface. [5] Major plant taxa in terrestrial ecosystems are members of the division Magnoliophyta (flowering plants), of which there are about 275,000 species, and the division Pinophyta (conifers), of which there are about 500 species.
