The common vole is hardly restricted in means of distribution and habitat and inhabits large areas of Eurasia but, apart from the Orkney vole, not the British Isles, where it is replaced by the related field vole, Microtus agrestis. As Microtus arvalis followed human civilization, primary and secondary habitats can be distinguished.
Blyth's vole has a head-and-body length of between 98 and 128 mm (3.86 and 5.04 in) and a tail length of 26 to 35 mm (1.02 to 1.38 in). The dorsal fur is light yellowish-brown, the underparts are yellowish-grey and there is a gradual transition where the two colours meet.
Unlike other voles in the range, only the creeping vole and the (much larger) water vole have five plantar tubercles on the hindfeet. [5] They are Pentadactyl, although the pollex is reduced in size and lack a claw. [5] They walk with their feet planted firmly on the ground (plantigrade locomotion). [5] The foot pads have a moderate amount of ...
Eastern meadow voles are active year-round [8] [9] and day or night, with no clear 24-hour rhythm in many areas. [10] Most changes in activity are imposed by season, habitat, cover, temperature, and other factors. Eastern meadow voles have to eat frequently, and their active periods (every two to three hours) are associated with food digestion.
The narrow-headed vole has a very extensive range and although populations fluctuate, no particular threats have been identified with this species and overall the population seems stable. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern". [1]
Alfisol and Ultisol soil types are particularly favored due to being favorable to the vole's burrowing system. [2] Voles feed on both the roots and stem system and the vegetation of plants, as well as fruits, seeds, bark, subterranean fungus and insects. [4] Because they feed on roots and tubers, voles do not need to drink water much. [3]
It is listed on the IUCN Red List as vulnerable. [1] Although historically considered to be a member of the same species as the European water vole, Musser and Carleton (2005) considered it distinct enough to warrant full species status. It is threatened for many of the same reasons as the European water vole, and a campaign is currently ...
The North American water vole or just water vole (Microtus richardsoni) is the largest North American vole. It is found in the northwestern United States and southern parts of western Canada . This animal has been historically considered a member of genus Arvicola , but molecular evidence demonstrates that it is more closely related to North ...
