In physical geography, tundra 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, alpine tundra, and Antarctic tundra.
Norway is a country located in Northern Europe in the northern and western parts of the Scandinavian Peninsula. The majority of the country borders water, including the Skagerrak inlet to the south, the North Sea to the southwest, the North Atlantic Ocean to the west, and the Barents Sea to the north. It has a land border with Sweden to the east; to the northeast it has a shorter border with Finland and an even shorter border with Russia.
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra.
Belkovsky Island is the westernmost island of the Anzhu Islands subgroup of the New Siberian Islands archipelago in the Laptev Sea.
Polar ecology is the relationship between plants and animals in a polar environment. Polar environments are in the Arctic and Antarctic regions. Arctic regions are in the Northern Hemisphere, and it contains land and the islands that surrounds it. Antarctica is in the Southern Hemisphere and it also contains the land mass, surrounding islands and the ocean. Polar regions also contain the subantarctic and subarctic zone which separate the polar regions from the temperate regions. Antarctica and the Arctic lie in the polar circles. The polar circles are imaginary lines shown on maps to be the areas that receives less sunlight due to less radiation. These areas either receive sunlight or shade 24 hours a day because of the earth's tilt. Plants and animals in the polar regions are able to withstand living in harsh weather conditions but are facing environmental threats that limit their survival.
The Arctic Cordillera is a terrestrial ecozone in northern Canada characterized by a vast, deeply dissected chain of mountain ranges extending along the northeastern flank of the Canadian Arctic Archipelago from Ellesmere Island to the northeasternmost part of the Labrador Peninsula in northern Labrador and northern Quebec, Canada. It spans most of the eastern coast of Nunavut with high glaciated peaks rising through ice fields and some of Canada's largest ice caps, including the Penny Ice Cap on Baffin Island. It is bounded to the east by Baffin Bay, Davis Strait and the Labrador Sea while its northern portion is bounded by the Arctic Ocean.
The Kerguelen Islands are part of the Southern Indian Ocean Islands tundra ecoregion that includes several subantarctic islands. In this cold climate plant life is mainly limited to grasses, mosses and lichens, although the islands are also known for the indigenous edible Kerguelen cabbage. The islands are at the Antarctic Convergence, where cold water moving up from the Antarctic mixes with the warmer water of the Indian Ocean. As a consequence, marine mammals, especially seals, and seabirds and penguins are numerous.
The North American Arctic is composed of the northern polar regions of Alaska (USA), Northern Canada and Greenland. Major bodies of water include the Arctic Ocean, Hudson Bay, the Gulf of Alaska and North Atlantic Ocean. The North American Arctic lies above the Arctic Circle. It is part of the Arctic, which is the northernmost region on Earth. The western limit is the Seward Peninsula and the Bering Strait. The southern limit is the Arctic Circle latitude of 66° 33’N, which is the approximate limit of the midnight sun and the polar night.
The wildlife of Russia inhabits terrain that extends across 12 time zones and from the tundra region in the far north to the Caucasus Mountains and prairies in the south, including temperate forests which cover 70% of the country. Russia's forests comprise 22% of the forest in the world as well as 33% of all temperate forest.
Gyda National Park is the northernmost national park in the Western Siberia. The park covers arctic terrain of the Gyda Peninsula and nearby islands in the Kara Sea. It is situated in the Tazovsky District of Yamalo-Nenets Autonomous Okrug. Until 2019, it was a 'zapovednik'.
Taymyr Nature Reserve is a Russian 'zapovednik' located in the northern lowlands of Siberia, on the Taimyr Peninsula, and on the coast of the Laptev Sea of the Arctic Ocean. The reserve includes the most northern forest of Dahurian larch in the world, and also the most northern mainland mountain range in the world. The protected area was established to protect the breeding grounds of the Red-breasted goose as well as the summer residences of wild reindeer and the biodiversity of the Lake Taymyr. The reserve is situated about 120 km east of the town of Norilsk, and 3,000 km northeast of Moscow, in the Taymyrsky Dolgano-Nenetsky District of Krasnoyarsk Krai. In 1995, the site was designated a UNESCO MAB Reserve. The reserve was formally established in 1979, and covers an area of 1,781,928 ha (6,880.06 sq mi).
Nenets Nature Reserve is a Russian 'zapovednik' in the northeast of European Russia on the coast of the Barents Sea and the delta of the Pechora River, about 800 km northeast of Arkhangelsk. With abundant wetlands, rivers, and sea islands, the reserve is an important point on the Atlantic migratory path for birds that winter in Western Europe and nest in the Eastern Europe and Western Siberian Tundra. Also present are large breeding grounds for the Atlantic Walrus. The reserve is situated in the Zapolyarny District of Nenets Autonomous Okrug. It was formally established in 1997, and covers and area of 313,400 ha (1,210 sq mi), of which 181,000 ha (700 sq mi) is over water.
The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, 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.
The fauna of Iceland is the animal life which resides on the island of Iceland and its coasts, located in the north Atlantic Ocean just south of the Arctic Circle. This fauna includes a number of birds, mammals, fish, and invertebrates. The Arctic fox is the only land mammal native to Iceland, although a number of other mammals have been introduced following the human settlement of Iceland.
The Arctic desert ecoregion is a terrestrial ecoregion that covers the island groups of Svalbard, Franz Josef Land, Severny Island and Severnaya Zemlya in the Arctic Ocean, above 75 degrees north latitude. The region is covered with glaciers, snow, and bare rock in a harshly cold environment. The temperature does rise above freezing for short periods in the summer, so some ice melt occurs, and the area supports colonies of sea birds and mammals. It has an area of 161,400 square kilometres (62,300 sq mi).
The wildlife of Norway includes the diverse flora and fauna of Norway. The habitats include high mountains, tundras, rivers, lakes, wetlands, sea coast and some lower cultivated land in the south. Mainland Norway has a long coastline, protected by skerries and much dissected by fjords, and the mostly-icebound archipelago of Svalbard lies further north. The flora is very varied and a large range of mammals, birds, fish and invertebrate species live here, as well as a few species of reptiles and amphibians.
Located in the Scandinavian Peninsula, Sweden is a mountainous country dominated by lakes and forests. Its habitats include mountain heath, montane forests, tundra, taiga, beech forests, rivers, lakes, bogs, brackish, marine coasts, and cultivated land. The climate of Sweden is mild for a country at this latitude, largely owing to the significant maritime influence.
The Iceland boreal birch forests and alpine tundra ecoregion covers the island of Iceland in the North Atlantic. The island is volcanic in origin with basaltic soils, and the cold northerly climate prevents any significant crop agriculture. Because the island is young and isolated from larger land masses, species biodiversity is relatively low. Forest cover has been reduced to about 1% of the original birch forest by a long history of timber extraction and soil erosion caused by sheep grazing. Blanket bogs are common.
The Torngat Mountain tundra ecoregion covers the Torngat Mountains on the northeastern tip of the Labrador Peninsula where the provinces of Quebec and Newfoundland and Labrador meet. The mountains feature glacially carved U-shaped valleys and deep fjords. The vegetation over most of the territory is that of arctic tundra, herbaceous cover, or bare rock. The region supports seasonal polar bears, black bears, and caribou. The Atlantic coast is on the Atlantic Flyway for migratory birds.
The Tundra of North America is a Level I ecoregion of North America designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas.
