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.
Chionophiles are any organisms that can thrive in cold winter conditions. These animals have specialized adaptations that help them survive the harshest winters.
The fauna of Maine include several diverse land and aquatic animal species, especially those common to the North Atlantic Ocean and deciduous forests of North America. Some of these creatures' habitats has been reduced or fully removed.
The fauna of Canada consist of approximately 200 mammal species, over 460 native bird species, 43 amphibian species, 43 reptile species, and 1,200 fish species. The biology survey of Canada cites that there are approximately 55,000 species of insects, and 11,000 species of mites and spiders.
The wildlife of Alaska is both diverse and abundant. The Alaskan Peninsula provides an important habitat for fish, mammals, reptiles, and birds. At the top of the food chain are the bears. Alaska contains about 70% of the total North American brown bear population and the majority of the grizzly bears, as well as black bears and Kodiak bears. In winter, polar bears can be found in the Kuskokwim Delta, St. Matthew Island, and at the southernmost portion of St. Lawrence Island. Other major mammals include moose and caribou, bison, wolves and wolverines, foxes, otters and beavers. Fish species are extensive, including: salmon, graylings, char, rainbow and lake trout, northern pike, halibut, pollock, and burbot. The bird population consists of hundreds of species, including: bald eagles, owls, falcons, ravens, ducks, geese, swans, and the passerines. Sea lions, seals, sea otters, and migratory whales are often found close to shore and in offshore waters. The Alaskan waters are home to two species of turtles, the leatherback sea turtle and the green sea turtle. Alaska has two species of frogs, the Columbia spotted frog and wood frog, plus two introduced species, the Pacific tree frog and the red-legged frog. The only species of toad in Alaska is the western toad. There are over 3,000 recorded species of marine macroinvertebrates inhabiting the marine waters, the most common being the various species of shrimp, crab, lobster, and sponge.
The fauna of Europe is all the animals living in Europe and its surrounding seas and islands. Europe is the western part of the Palearctic realm. Lying within the temperate region, the wildlife is not as rich as in the hottest regions, but is nevertheless diverse due to the variety of habitats and the faunal richness of Eurasia as a whole.
This is a list of the fauna of Finland. Finland borders Sweden to the west, Russia to the east, and Norway to the north, while Estonia lies to its south across the Gulf of Finland, allowing an ecological mix. Finland contains many species of mammals, birds, and fish, but only a few reptiles and amphibians. This article discusses all the vertebrate animals which can be found on Finland itself, not the oceans.
Although the bulk of its area is covered by ice caps inhospitable to most forms of life, Greenland's terrain and waters support a wide variety of plant and animal species. The northeastern part of the island is the world's largest national park. The flora and fauna of Greenland are strongly susceptible to changes associated with climate change.
The flora and fauna of the Outer Hebrides in northwest Scotland comprises a unique and diverse ecosystem. A long archipelago, set on the eastern shores of the Atlantic Ocean, it attracts a wide variety of seabirds, and thanks to the Gulf Stream a climate more mild than might be expected at this latitude. Because it is on the Gulf Stream, it also occasionally gets exotic visitors.
Svalbard is an Arctic, wilderness archipelago comprising the northernmost part of Norway. It is mostly uninhabited, with only about 3,000 people, yet covers an area of 61,020 square kilometres (23,560 sq mi).
The fauna of the State of California may be the most diverse in the United States of America. Of the Lower 48 conterminous states, California has the greatest diversity in climate, terrain and geology in general. The state's six life zones are the lower Sonoran (desert); upper Sonoran ; transition ; and the Canadian, Hudsonian, and Arctic zones, comprising California's highest elevations. California’s diverse geography gives rise to dozens of different ecosystems, each of which has its own unique native plants and animals. California is a huge state, the 3rd largest in the U.S., and can range broadly in habitat type.
The fauna of the U.S. State of Nevada is mostly species adapted to desert, temperature extremes and to lack of moisture. With an average annual rainfall of only about 7 inches (180 mm), Nevada is the driest – and has the largest percentage of its total area classified as desert – of all states in the United States. Two-thirds of the state is located within the largest desert on the North American continent, the Great Basin Desert, while the lower one-third is the Mojave Desert.
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).
Kuururjuaq National Park is a 4,460 km2 (1,720 sq mi) national park, created in May 2009 and managed by the Kativik Regional Government, in northeast Quebec, Canada. It stretches all the way from Ungava Bay to Mount D'Iberville, which is on the Newfoundland and Labrador and Quebec border. Mount D'Iberville, at an altitude of 1,646 m (5,400 ft), is the highest mountain in eastern continental Canada, dominating over the entire Torngat Mountain range. The 166 km (103 mi) Koroc River runs through the national park to Ungava Bay. Kuururjuaq National Park contains a variety of different ecosystems and comprises three natural regions: the Torngat Mountain Foothills, the George River Plateau and the Ungava Coast. Like other Nunavik parks, Kuururjuaq National Park is developed and managed by the Inuit.
The wildlife of Iceland is the wild plant and animal life found on the island of Iceland, located in the north Atlantic Ocean just south of the Arctic Circle. The flora, fauna, and funga is limited by the geography and climate of the island. The habitats on the island include high mountains, lava fields, tundras, rivers, lakes and a coastal plain of varying width. There is a long coastline, much dissected by fjords, especially in the west, north and east, with many offshore islets.
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.
