The Beringian lemming or Beringian brown lemming (Lemmus nigripes) is a species of lemming found in Russia and North America.
It was formerly considered conspecific with the Canadian lemming (L. trimucronatus) with both species being grouped together as the "North American brown lemming", but genetic studies have affirmed both as being distinct species from one another. [1]
This species is found on both sides of the Bering Sea, and its distribution roughly coincides with the former landmass of Beringia, which it likely inhabited prior to its partial submergence. [2]
In Siberia, it is found east of the Kolyma River (with the East Siberian lemming, L. paulus, being found west of the river) ranging throughout most of Chukotka, northern Magadan, and northern Kamchatka Krai. A disjunct population is also present in the southern Kamchatka Peninsula, which is otherwise inhabited only by L. paulus. [2]
In North America, it is found throughout most of the US state of Alaska (including many of the islands, such as St. Lawrence Island and Nunivak Island) and adjoining portions of Yukon, Canada, but it is not found south of the Alaska Range, where it is replaced by L. trimucronatus. [2]
The snowy owl, also known as the polar owl, the white owl and the Arctic owl, is a large, white owl of the true owl family. Snowy owls are native to the Arctic regions of both North America and the Palearctic, breeding mostly on the tundra. It has a number of unique adaptations to its habitat and lifestyle, which are quite distinct from other extant owls. One of the largest species of owl, it is the only owl with mainly white plumage. Males tend to be a purer white overall while females tend to have more extensive flecks of dark brown. Juvenile male snowy owls have dark markings that may appear similar to females until maturity, at which point they typically turn whiter. The composition of brown markings about the wing, although not foolproof, is the most reliable technique to age and sex individual snowy owls.
The Kamchatka Peninsula is a 1,250-kilometre-long (777 mi) peninsula in the Russian Far East, with an area of about 270,000 km2 (100,000 sq mi). The Pacific Ocean and the Sea of Okhotsk make up the peninsula's eastern and western coastlines, respectively. Immediately offshore along the Pacific coast of the peninsula runs the 10,500-metre-deep (34,449 ft) Kuril–Kamchatka Trench.
The Arvicolinae are a subfamily of rodents that includes the voles, lemmings, and muskrats. They are most closely related to the other subfamilies in the Cricetidae. Some authorities place the subfamily Arvicolinae in the family Muridae along with all other members of the superfamily Muroidea. Some refer to the subfamily as the Microtinae or rank the taxon as a full family, the Arvicolidae.
The Norway lemming, also known as the Norwegian lemming is a common species of lemming found in northern Fennoscandia, where it is the only vertebrate species endemic to the region. The Norway lemming dwells in tundra and fells, and prefers to live near water. Adults feed primarily on sedges, grasses and moss. They are active at both day and night, alternating naps with periods of activity.
Lemmini is a tribe of lemmings in the subfamily Arvicolinae. Species in this tribe are:
The Dolly Varden trout is a species of salmonid ray-finned fish native to cold-water tributaries of the Pacific Ocean in Asia and North America. Despite the name "trout", it belongs to the genus Salvelinus (chars), which includes 51 recognized species, the most prominent being the brook, lake and bull trout as well as the Arctic char. Although many populations are semi-anadromous, riverine and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the Salvelinus alpinus complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap.
The Amur lemming is a species of lemmings found near the Amur River in Siberia.
The genus Lemmus contains several species of lemming sometimes referred to as the true lemmings. They are distributed throughout the Holarctic, particularly in the Palearctic.
The Paleo-Arctic Tradition is the name given by archaeologists to the cultural tradition of the earliest well-documented human occupants of the North American Arctic, which date from the period 8000–5000 BC. The tradition covers Alaska and expands far into the east, west, and the Southwest Yukon Territory.
The Canadian lemming or Nearctic brown lemming is a small North American lemming.
The grey red-backed vole or the grey-sided vole is a species of vole. An adult grey red-backed vole weighs 20-50 grams. This species ranges across northern Eurasia, including northern China, the northern Korean Peninsula, and the islands of Sakhalin and Hokkaidō. It is larger and longer-legged than the northern red-backed vole, which covers a similar range and it is also sympatric with the Norwegian lemming.
The WestSiberian lemming or Western Siberian brown lemming is a true lemming species found in the Russian Federation. Like other lemmings, it belongs to the Cricetidae family of rodents.
Bear hunting is the act of hunting bears. Bear have been hunted since prehistoric times for their meat and fur. In addition to being a source of food, in modern times they have been favored by big game hunters due to their size and ferocity. Bear hunting has a vast history throughout Europe and North America, and hunting practices have varied based on location and type of bear.
Promise Island is located near the western shore of Hudson Bay. It is barely a square kilometre in area and rises 300 ft (91 m) in elevation on its northern side. It is located about 9 km (5.6 mi) from the community of Chesterfield Inlet, Nunavut, Canada, and is part of a loose chain of small islands running along the coast, including the Wag Islands and Pitsiulartok.
A lemming is a small rodent, usually found in or near the Arctic in tundra biomes. Lemmings form the subfamily Arvicolinae together with voles and muskrats, which form part of the superfamily Muroidea, which also includes rats, mice, hamsters, and gerbils. In popular culture, a longstanding myth holds that they exhibit herd mentality and jump off cliffs, committing mass suicide.
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.
The Haida ermine is a mustelid species endemic to a few islands off the Pacific Northwest of North America, namely Haida Gwaii in Canada and the southern Alexander Archipelago in the U.S. state of Alaska.
The East Siberian lemming, Eastern Siberian brown lemming, or Ognev's lemming is a species of lemming endemic to Russia, where it has a disjunct distribution throughout parts of Siberia east of the Verkhoyansk Range.
