The Arctic fox, 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 Arctic tundra biome. It is well 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 46 to 68 cm, with a generally rounded body shape to minimize the escape of body heat.
The curlew sandpiper is a small wader that breeds on the tundra of Arctic Siberia.
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.
The northern bog lemming is a small North American lemming. It is one of two species in the genus Synaptomys, the other being the southern bog lemming (Synaptomys cooperi). Very little information is available about this species' life as they are hard to find and study. The northern bog lemming is a small, reddish-brown rodent with a short tail, and distinct markings on their upper teeth. These markings, along with having four pairs of teats, distinguishes this species from the southern bog lemming. The northern bog lemming lives in wet habitats in North America and is omnivorous, eating herbaceous material and invertebrates. They are thought to be extremely sociable animals and sexually mature at around 6 weeks old. Predators include most medium to larger sized carnivorous and omnivorous mammals that eat smaller mammals. The northern bog lemming is listed as a species of "Least Concern" by the IUCN Red List and is considered threatened or of concern in states such as Minnesota and Maine.
Lemmini is a tribe of lemmings in the subfamily Arvicolinae. Species in this tribe are:
The northern collared lemming or Nearctic collared lemming, sometimes called the Peary Land collared lemming in Canada, is a small lemming found in Arctic North America and Wrangel Island. At one time, it was considered to be a subspecies of the Arctic lemming. Some sources believe several other species of collared lemmings found in North America are actually subspecies of D. groenlandicus.
The Siberian roe deer, eastern roe deer, or Asian roe deer, is a species of roe deer found in northeastern Asia. In addition to Siberia and Mongolia, it is found in Kazakhstan, the Tian Shan Mountains of Kyrgyzstan, eastern Tibet, the Korean Peninsula and forested regions of northern China.
The Siberian weasel or kolonok is a medium-sized weasel native to Asia, where it is widely distributed and inhabits various forest habitats and open areas. It is therefore listed as Least Concern on the IUCN Red List.
Mice in the genus Dendromus are commonly referred to as African climbing mice or tree mice, although these terms are often used to describe all members of the subfamily Dendromurinae. The genus is currently restricted to sub-Saharan Africa, but fossils classified in the genus have been found from Late Miocene deposits in Arabia and Europe.
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 Arctic lemming is a species of rodent in the family Cricetidae.
The Shansei vole is a species of rodent in the family Cricetidae. It is found only in north-central China where its habitat is forests.
The West Siberian lemming or Western Siberian brown lemming is a true lemming species found in the Russian Federation. Like other lemmings, it belongs to the family Cricetidae of rodents.
The wood lemming is a species of rodent in the family Cricetidae. It belongs to the rodent subfamily Arvicolinae, so is a relative of the voles, lemmings, and muskrats. It is found in the taiga biome of China, Estonia, Finland, Mongolia, Norway, Russia, and Sweden.
Brants's whistling rat or Brants' whistling rat is one of two species of murid rodent in the genus Parotomys. It is found in Botswana, Namibia, and South Africa where its natural habitats are subtropical or tropical dry shrubland and pastureland. It was first described in 1834 by the Scottish zoologist Andrew Smith who named it in honour of the Dutch zoologist and author Anton Brants.
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 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.
The Beringian lemming or Beringian brown lemming is a species of lemming found in Russia and North America.
