The Hokkaido red-backed vole (Craseomys rex) is a species of rodent in the family Cricetidae. [2] It is found at high altitudes on the island of Hokkaido in Japan and at lower altitudes on some smaller islands nearby. Its natural habitat is temperate forests.
The Hokkaido red-backed vole occurs in the southwestern part of Hokkaido in the Hidaka Mountains, Daisetsuzan Volcanic Group, Teshio Mountains, and Kitami Mountains, and Shiribeshi Province, Oshima Subprefecture and Hiyama Subprefecture. It is also present at lower altitudes on the islands of Rishiri and Rebun, as well as Shikotan in the Kuril Islands and Shibotsu in the Habomai Islands. It is found in forests and is an adaptable species. [1] Population genetic structuring is rather strong on Hokkaido, with different regions being characterised by different genetic lineages. [3]
Despite having a total area of occupancy of less than 20,000 square kilometres (7,700 sq mi) and being considered rare, the Hokkaido red-backed vole is listed as being of "least concern" by the International Union for Conservation of Nature. This is because the population seems stable, the vole faces no significant threats and it is present in some protected areas. [1]
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 water voles are large voles in the genus Arvicola. They are found in both aquatic and dry habitat through Europe and much of northern Asia. A water vole found in Western North America was historically considered a member of this genus, but has been shown to be more closely related to members of the genus Microtus. Head and body lengths are 12–22 cm, tail lengths are 6.5–12.5 cm, and their weights are 70–250 g. The animals may exhibit indeterminate growth. They are thick-furred and have hairy fringes on their feet that improve their swimming ability.
The royal vole, also called the Korean red-backed vole, is a species of vole endemic to the Korean Peninsula. It lives underground in a burrow, emerging at night to feed on grasses, seeds and other vegetation. The International Union for Conservation of Nature has listed its conservation status as being of "least concern".
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.
Alticola is a genus of rodent in the family Cricetidae.
The silver mountain vole is a species of rodent in the family Cricetidae. They are distinguished by their silver-grey pelage, long vibrissae, rootless hypsodont molars and angular skull shape. Like many mammals of the Eurasian Steppe eco-region, they are well adapted to life in high altitudes, and can be found in mountain areas of Central Asia from Saur Mountains in the north-east to Kugitang Range in the west, and to Tibet and the Himalayas in the south.
Chionomys is a genus of rodent in the family Cricetidae.
The European snow vole or snow vole is a species of rodent in the family Cricetidae. It has dense, pale grey fur and a pale-coloured tail and can reach about 14 cm (5.5 in) long, with a tail which is 7 cm (2.8 in) long.
The Ganzu vole, Eva's red-backed vole, Eva's vole, Gansu vole, or Taozhou vole is a species of rodent in the family Cricetidae. It is found in mountain forests in China. The IUCN has assessed it as being of "least concern".
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 insular vole or St. Matthew Island vole is a species of rodent in the family Cricetidae. It occurs only on St. Matthew Island and the adjacent Hall Island, in Alaska. On these Bering Sea islands, insular voles live in damp lowland areas, on the lower slopes of mountains, and on rye grass-covered beaches. They are diurnal and eat plant matter. Birds and Arctic foxes prey on the voles.
The narrow-headed vole is a species of rodent in the family Cricetidae. It was previously placed in the genus Microtus, but modern listings either lump this into genus Lasiopodomys or split it out into Stenocranius. It ranges over northern and central Asia.
Blyth's vole is a species of rodent in the family Cricetidae. It was previously the only species in the genus Phaiomys, but was moved to Neodon in 2016. It is found in mountainous regions in northern India, Nepal and China. It is a burrowing rodent and lives in small colonies. It has a wide distribution and faces no particular threats so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The Sikkim mountain vole is a species of rodent in the family Cricetidae. It is found in Bhutan, India, Nepal and China.
The Japanese red-backed vole, Wakayama red-backed vole, or Anderson's red-backed vole is a species of rodent in the family Cricetidae. It is found only on the island of Honshu in Japan. It was first described by the British zoologist Oldfield Thomas in 1905. Thomas named it in honor of scientific collector Malcolm Playfair Anderson. The International Union for Conservation of Nature lists it as "least concern".
The Duke of Bedford's vole is a species of rodent in the family Cricetidae. After the Liangshan vole was removed from this genus, the Duke of Bedford's vole became the only member of the genus Proedromys. It is found only in mountainous parts of central China. It is a rare species and the International Union for Conservation of Nature has assessed its conservation status as being "vulnerable".
The Clethrionomyini are a tribe of forest voles in the subfamily Arvicolinae. This tribe was formerly known as Myodini, but when genus Myodes was deemed to be a junior synonym, the tribe was renamed. Species in this tribe are:
Neodon is a genus of rodent in the family Cricetidae. Species within Neodon are classified as relics of the Pleistocene epoch because the occlusal patterns resemble the extinct Allophaiomys.
The Lake Baikal mountain vole or Olkhon mountain vole is a species of rodent in the family Cricetidae. It is found principally on the Olkhon and Ogoi islands on Lake Baikal, in southern Siberia. While it was originally described as a species, Pavlinov and Rossolimo reassigned it as a subspecies of A. tuvinicus in 1987 before reinstating it as a species in 1998.
Craseomys is a genus of small, slender voles.
