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] While the taiga has a more moderate climate and permits a diversity of both non-vascular and ...
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 ...
11,563,300 [1] km 2 (4,464,600 sq mi) Climate type. ET. In physical geography, tundra (/ ˈtʌndrə, ˈtʊn -/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra.
The terrain is mountainous tundra and northern taiga. Since 1985 the zapovednik has been designated by UNESCO as a biosphere reserve. The name refers to the cultural area of Lapland, now preferably called Sápmi. The Lapland Nature Reserve was established in 1930. However, in 1951 along with many other zapovedniks of the Soviet Union it was ...
Arctic vegetation. About 1,702 species of plants live on the Arctic tundra, including flowering plants, short shrubs, herbs, grasses, and mosses. These plants are adapted to short, cold growing seasons. [1] They have the ability to withstand extremely cold temperatures in the winter (winter hardiness), and grow and reproduce in summer ...
Northern Europe. A composed satellite photograph of islands and continental areas in and surrounding the North Sea and Baltic Sea. The northern region of Europe has several definitions. A restrictive definition may describe northern Europe as being roughly north of the southern coast of the Baltic Sea, which is about 54°N, or may be based on ...
At lower altitude is low alpine tundra with continuous plant cover; dwarf birch and willows up to 1 m tall and grasslands, as well as numerous lakes and bogs. At still lower altitude is the adjacent montane birch zone with mountain downy birch ( Betula pubescens ); some stunted spruce and pine , and many lakes and bogs.
The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
