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.

Contents

Distribution

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]

Status

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]

<span class="mw-page-title-main">Arvicolinae</span> Subfamily of rodents

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.

<i>Arvicola</i> Genus of mammals (water voles)

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".

<span class="mw-page-title-main">Grey red-backed vole</span> Species of rodent

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 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.

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".
