Arvicolinae

The muskrat or common muskrat (Ondatra zibethicus) is a medium-sized semiaquatic rodent.

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. A longstanding myth claims that they exhibit herd mentality and jump off cliffs, committing mass suicide.

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.

Microtus is a genus of voles found in North America, Europe and northern Asia. The genus name refers to the small ears of these animals. They are stout rodents with short ears, legs and tails. They eat green vegetation such as grasses and sedges in summer, and grains, seeds, root and bark at other times. The genus is also called "meadow voles". thumb|Microtus skulls (Bailey, 1900) thumb|Microtus skull bases (Bailey, 1900)

Voles are small rodents that are relatives of lemmings and hamsters, but with a stouter body; a longer, hairy tail; a slightly rounder head; smaller eyes and ears; and differently formed molars (high-crowned with angular cusps instead of low-crowned with rounded cusps). They are sometimes known as meadow mice or field mice.

Arvicolini is a tribe of voles in the subfamily Arvicolinae.

Ondatrini is a tribe of semiaquatic rodents in the family Arvicolinae. They are known as muskrats. They are related to voles and lemmings.

Bramus is a genus of fossorial rodents. It formerly contained only the extinct North African species Bramus barbarus. Both species in Bramus were moved to this genus from Ellobius. They differ from Ellobius in being larger, having a distinct sagital crest, and other features of the teeth and skull. They also occur allopatrically from Ellobius. They are sexually dimorphic, with females being larger than males. The genus comprises two extant species: Southern mole vole, Bramus fuscocapillus (Blyth, 1843) Transcaucasian mole vole, Bramus lutescens (Thomas, 1897)
