ANWR Drilling
The Arctic National Wildlife Refuge (ANWR, pronounced as “''ANN-warr''”) or Arctic Refuge is a national wildlife refuge in northeastern Alaska, United States, on traditional Iñupiaq and Gwich'in lands. The refuge is of the Alaska North Slope region, with a northern coastline and vast inland forest, taiga, and tundra regions. ANWR is the largest national wildlife refuge in the country, slightly larger than the Yukon Delta National Wildlife Refuge. The refuge is administered from offices in Fairbanks. ANWR is home to a diverse range of endemic mammal species; notably, it is one of the few North American locations with all three endemic American bears—the polar bear, grizzly bear, and American black bear, each of which resides predominantly in its own ecological niche. Besides the bears, other mammal species include the moose, caribou, wolves, red and Arctic fox, Canada lynx, wolverine, pine marten, American beaver, and North American river otter.

North Slope Borough, Alaska
The North Slope Borough is the northernmost borough in the US state of Alaska and, thus, the northernmost county or equivalent of the United States as a whole. As of the 2020 census, the population was 11,031. The borough seat and largest city, comprising nearly half of the borough’s population, is Utqiaġvik (known as Barrow from 1901 to 2016), the northernmost settlement in the United States. History The borough was established in 1972 by an election of the majority Indigenous people in the region, following Congressional passage of the Alaska Native Claims Settlement Act. Most are Inupiat. The borough was named for the Alaska North Slope basin. In 1974, it adopted a Home Rule Charter, enabling it to exercise any legitimate governmental power. The borough has first-class status and exercises the powers of planning, zoning, taxation, and schools. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grizzly Bear
The grizzly bear (''Ursus arctos horribilis''), also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America. In addition to the mainland grizzly (''Ursus arctos horribilis''), other morphological forms of brown bear in North America are sometimes identified as grizzly bears. These include three living populations—the Kodiak bear (''U. a. middendorffi''), the Kamchatka brown bear, Kamchatka bear (''U. a. beringianus''), and the Alaska Peninsula brown bear, peninsular grizzly (''U. a. gyas'')—as well as the extinct California grizzly bear, California grizzly (''U. a. californicus''†) and Mexican grizzly bear, Mexican grizzly (formerly ''U. a. nelsoni''†). On average, grizzly bears near the coast tend to be larger while inland grizzlies tend to be smaller. The Ussuri brown bear (''U. a. lasiotus''), inhabiting the Ussuri Krai, Sakhalin, the Amur Oblast, the Shantar Islands, Iturup Island, and Kun ...

Mountain Goats
The mountain goat (''Oreamnos americanus''), also known as the Rocky Mountain goat, is a cloven-footed mammal that is endemic to the remote and rugged mountainous areas of western North America. A subalpine to truly alpine species, it is a sure-footed climber commonly seen on sheer rock faces, near-vertical cliffs and icy passages. Mountain goats generally avoid venturing down into lower elevations—except during seasonal food shortages or during particularly bad weather—as the extreme elevation which they inhabit is their primary defense against predators such as black and brown bears, pumas and wolves. Despite its vernacular name and both genera being in the same subfamily ( Caprinae), the mountain goat is not a member of '' Capra'', the genus that includes all true goats (such as the wild goat (''Capra aegagrus''), from which the domestic goat is derived); rather, it is more closely allied with the other bovids known as “goat-antelopes”, including the European ch ...

North American River Otter
The North American river otter (''Lontra canadensis''), also known as the northern river otter and river otter, is a semiaquatic mammal that endemism, lives only on the North American continent throughout most of Canada, along the coasts of the United States and its inland waterways. An adult North American river otter can weigh between . The river otter is protected and insulated by a thick, water-repellent coat of fur. The North American river otter, a member of the subfamily Lutrinae in the weasel family (Mustelidae), is equally versatile in the water and on land. It establishes a burrow close to the water's edge in river, lake, swamp, coastal shoreline, tidal flat, or estuary ecosystems. The den typically has many tunnel openings, one of which generally allows the otter to enter and exit the body of water. Female North American river otters give birth in these burrows, producing litters of one to six young. North American river otters, like most predators, prey upon the most ...

American Beaver
The North American beaver (''Castor canadensis'') is one of two extant beaver species, along with the Eurasian beaver (''Castor fiber''). It is native to North America and has been introduced in South America (Patagonia) and Europe (primarily Finland and Karelia). The North American beaver is one of the national symbols of Canada and the official state mammal of Oregon and New York. North American (Canadian) beavers are widespread across the continental United States, Canada, southern Alaska, and some parts of northern Mexico. In Canada and the United States, the North American beaver is often referred to simply as "beaver", although this can cause some confusion because another distantly related rodent, '' Aplodontia rufa'', is often called the "mountain beaver". Other vernacular names, including American beaver and Canadian beaver, distinguish this species from the other extant beaver species, '' Castor fiber'', which is native to Eurasia.

Pine Marten
The European pine marten (''Martes martes''), also known as the pine marten, is a mustelid native to and widespread in most of Europe, Asia Minor, the Caucasus, and parts of Iran, Iraq, and Syria. It is listed as Least Concern on the IUCN Red List. It is less commonly known as baum marten or sweet marten. Description The European pine marten's fur is usually light to dark brown. It is short and coarse in the summer, growing longer and silkier during the winter. It has a cream- to yellow-coloured "bib" marking on its throat. Its body is up to long, with a bushy tail of about . It weighs around ; males are slightly larger than females. It has excellent senses of sight, smell, and hearing. Distribution and habitat Britain and Ireland The European pine marten was for many years common only in northwestern Scotland. A study in 2012 found that it has spread from the Scottish Highlands north into Sutherland and Caithness and southeastwards from the Great Glen into Moray, Aberde ...

Wolverine
The wolverine ( , ; ''Gulo gulo''), also called the carcajou or quickhatch (from East Cree, ''kwiihkwahaacheew''), is the largest land-dwelling species, member of the family Mustelidae. It is a muscular carnivore and a solitary animal. The wolverine has a reputation for ferocity and strength out of proportion to its size, with the documented ability to kill prey many times larger than itself. The wolverine is found primarily in remote reaches of the Northern Taiga, boreal forests and subarctic and alpine tundra of the Northern Hemisphere, with the greatest numbers in Northern Canada, the U.S. state of Alaska, the mainland Nordic countries of Europe, and throughout western Russia and Siberia. Its population has steadily declined since the 19th century owing to trapping, range reduction and habitat fragmentation. The wolverine is now essentially absent from the southern end of its range in both Europe and North America. Naming The wolverine's questionable reputation as an insa ...

Canada Lynx
The Canada lynx (''Lynx canadensis'') or Canadian lynx is one of the four living species in the genus ''Lynx''. It is a medium-sized wild cat characterized by long, dense fur, triangular ears with black tufts at the tips, and broad, snowshoe-like paws. Its hindlimbs are longer than the forelimbs, so its back slopes downward to the front. The Canada lynx stands tall at the shoulder and weighs between . It is a good swimmer and an agile climber. The Canada lynx was first scientific description, described by Robert Kerr (writer), Robert Kerr in 1792. Three subspecies have been proposed, but their valid name (zoology), validity is doubted; it is mostly considered a monotypic species. It ranges across Alaska, Canada and northern areas of the contiguous United States, where it predominantly inhabits dense Taiga, boreal forests. It is a Specialist and generalist species, specialist predator and depends heavily on the snowshoe hare (''Lepus americanus'') for food. This leads to a Lot ...

Arctic Fox
The Arctic fox (''Vulpes lagopus''), also known as the white fox, polar fox, or snow fox, is a small species of fox native to the Arctic regions of the Northern Hemisphere and common throughout the Tundra#Arctic tundra, Arctic tundra biome. It is well adaptation, adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. It has a large and very fluffy tail. In the wild, most individuals do not live past their first year but some exceptional ones survive up to 11 years. Its body length ranges from , with a generally rounded body shape to minimize the escape of body heat. The Arctic fox preys on many small creatures such as lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds. It also eats carrion, berries, seaweed, and insects and other small invertebrates. Arctic foxes form Monogamy in animals, monogamous pairs during the breeding season and they stay together to raise their young in complex underground dens. ...

Red Fox
The red fox (''Vulpes vulpes'') is the largest of the true foxes and one of the most widely distributed members of the order Carnivora, being present across the entire Northern Hemisphere including most of North America, Europe and Asia, plus parts of North Africa. It is listed as least concern on the IUCN Red List. Its range has increased alongside human expansion, having been Foxes in Australia, introduced to Australia, where it is considered harmful to native small and medium-sized rodents and marsupials. Due to its impact on native species, it is included on the list of the "List of the world's 100 worst invasive species, world's 100 worst invasive species". The red fox originated in Eurasia during the Middle Pleistocene at least 400,000 years ago and later colonised North America sometime prior to 130,000 years ago. Among the true foxes, the red fox represents a more progressive form in the direction of Carnivore, carnivory. Apart from its large size, the red fox is distin ...

Grey Wolf
The wolf (''Canis lupus''; : wolves), also known as the grey wolf or gray wolf, is a canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, including the dog and dingo, though grey wolves, as popularly understood, only comprise naturally-occurring wild subspecies. The wolf is the largest wild extant member of the family Canidae, and is further distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The wolf's fur is usually mottled white, brown, grey, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large pr ...

Reindeer
The reindeer or caribou (''Rangifer tarandus'') is a species of deer with circumpolar distribution, native to Arctic, subarctic, tundra, taiga, boreal, and mountainous regions of Northern Europe, Siberia, and North America. It is the only representative of the genus ''Rangifer''. More recent studies suggest the splitting of reindeer and caribou into six distinct species over their range. Reindeer occur in both Animal migration, migratory and wiktionary:sedentary#Adjective, sedentary populations, and their herd sizes vary greatly in different regions. The tundra subspecies are adapted for extreme cold, and some are adapted for long-distance migration. Reindeer vary greatly in size and color from the smallest, the Svalbard reindeer (''R.'' (''t.'') ''platyrhynchus''), to the largest, Osborn's caribou (''R. t. osborni''). Although reindeer are quite numerous, some species and subspecies are in decline and considered Vulnerable species, vulnerable. They are unique among deer (Ce ...
