Dicrostonychini

	Dicrostonychini Dicrostonychini is a tribe of lemmings in the subfamily Arvicolinae 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 (comprising the hamsters and New World rats and mice). Some authorities p .... It contains only one extant genus, as well as one extinct genus. A 2021 study found Dicrostonychini to also include the genera previously placed in the tribe Phenacomyini, and found this combined Dicrostonychini to be the sister group to the muskrats (tribe Ondatrini).

	Lemmings A lemming is a small rodent, usually found in or near the Arctic in tundra biomes. Lemmings form the subfamily Arvicolinae (also known as Microtinae) 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. Description and habitat Lemmings measure around in length and weigh around . Lemmings are quite rounded in shape, with brown and black, long, soft fur. They have a very short tail, a stubby, hairy snout, short legs, and small ears. They have a flattened claw on the first digit of their front feet, which helps them to dig in the snow. They are herbivorous, feeding mostly on mosses and grasses. They also forage through the snow surface to find berries, leaves, shoots, roots, bulbs, and lichens. Lemmings choose their preferred dietary vegetation disproportionately to its occurren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Arvicolinae 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 (comprising the hamsters and New World rats and mice). 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 (yielding the adjective "microtine") or rank the taxon as a full family, the Arvicolidae. The Arvicolinae are the most populous group of Rodentia in the Northern Hemisphere. They often are found in fossil occlusions of bones cached by past predators such as owls and other birds of prey. Fossils of this group are often used for biostratigraphic dating of paleontological and archeological sites in North America and Europe. Description The most convenient distinguishing feature of the Arvicolinae is the nature of their molar teeth, which have prismatic cusps in the shape of alt ...

	Phenacomyini Phenacomyini is a tribe of voles in the subfamily Arvicolinae. It contains five species in two genera, all of which are found in North America. Species in this tribe are: * Genus '' Arborimus'' - tree voles White-footed vole, ''A. albipes'' Red tree vole, ''A. longicaudus'' ** Sonoma tree vole, ''A. pomo'' * Genus '' Phenacomys'' - heather voles Western heather vole, ''P. intermedius'' Eastern heather vole, ''P. ungava'' The fossil taxa '' Hibbardomys'' and '' Paraphenacomys'' likely also belong to this tribe. The phylogenetic affinities of this tribe have been disputed; some authors have classified them as belonging in the same clade as Arvicolini and Myodini, while others ally them with the otherwise Arctic tribe Dicrostonychini Dicrostonychini is a tribe of lemmings in the subfamily Arvicolinae The Arvicolinae are a subfamily of rodents that includes the voles, lemmings, and muskrats.

	Ondatrini Ondatrini is a tribe of semiaquatic rodents in the family Arvicolinae. They are known as muskrats. They are related to voles and lemmings. Classification It contains two extant species, each in their own genus, both of which are native to North America: * Genus '' Neofiber'' ** Round-tailed muskrat, ''N. alleni'' * Genus '' Ondatra'' Muskrat, ''O. zibethicus'' Of these, the muskrat (''O. zibethicus'') is found throughout North America aside from the warmer or drier regions, and has been introduced to Eurasia. The round-tailed muskrat (''N. alleni'') is only found in Florida and adjacent Georgia, just outside of the range of ''O. zibethicus''. Some authorities place both genera in different tribes (Ondatrini for ''Ondatra'', Neofibrini for ''Neofiber''), but the American Society of Mammalogists places both in Ondatrini, and some molecular evidence supports a close relation between both genera. Some phylogenetic evidence indicates that Balkan snow vole (''Dinaromys bogdano ... [...More Info...] [...Related Items...] OR:** [Wikipedia] [Google] [Baidu]
