Vole
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. Vole species form the subfamily Arvicolinae with the lemmings and the muskrats. There are approximately 155 different vole species. Description Voles are small rodents that grow to , depending on the species. Females can have five to ten litters per year, though with an average lifespan of three months and requiring one month to adulthood, two litters is the norm. Gestation lasts for three weeks and the young voles reach sexual maturity in a month. As a result of this biological exponential growth, vole populations can grow very large within a short time. One mating pair can produce 100 offspring every year. Voles outwardly resemble several other ... [...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 alternat ...

Bank Vole
The bank vole (''Clethrionomys glareolus'') is a small vole with red-brown fur and some grey patches, with a tail about half as long as its body. A rodent, it lives in woodland areas and is around in length. The bank vole is found in much of Europe and in northwestern Asia. It is native to Great Britain but not to Ireland, where it has been accidentally introduced, and has now colonised much of the south and southwest. The bank vole lives in woodland, hedgerows and other dense vegetation, such as bracken and bramble. Its underground chamber is lined with moss, feathers and vegetable fibre and contains a store of food. It can live for eighteen months to two years in the wild and over 42 months in captivity and is mostly herbivorous, eating buds, bark, seeds, nuts, leaves and fruits and occasionally insects and other small invertebrates. It readily climbs into scrub and low branches of trees although it is not as versatile as a mouse. It breeds in shallow burrows, the female reari ...

Myodini
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: *Tribe Clethrionomyini **Genus ''Alticola'' - voles from Central Asia ***Subgenus ''Alticola'' **** White-tailed mountain vole, ''A. albicauda'' **** Silver mountain vole, ''A. argentatus'' **** Gobi Altai mountain vole, ''A. barakshin'' ****'' Alticola kohistanicus'' **** Central Kashmir vole, ''A. montosus'' **** Lake Baikal mountain vole, ''A. olchonensis'' ****'' Alticola parvidens'' **** Royle's mountain vole, ''A. roylei'' **** Mongolian silver vole, ''A. semicanus'' **** Stolička's mountain vole, ''A. stoliczkanus'' **** Flat-headed vole, ''A. strelzovi'' **** Tuva silver vole, ''A. tuvinicus'' ***Subgenus ''Aschizomys'' ****Lemming vole, ''A. lemminus'' **** Large-eared vole, ''A. macrotis'' **Genus '' Caryomys'' *** Ganzu vole, ''C. eva'' *** K ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

Phenacomyini
Phenacomyini is a Tribe (biology), tribe of Vole, 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 and place them outside the clade containing other voles. A 2021 phylogenetic study found Phenacomyini to form a sister group to Dicrostonychini and synonymized it with them. References Voles and lemmings Mammal ...

Arvicolini
Arvicolini is a tribe of voles in the subfamily Arvicolinae. A 2021 study found that '' Arvicola'' is distinct from the other extant genera in the tribe, instead being sister to the tribe Lagurini. The current species listing of the American Society of Mammalogists lists only ''Arvicola'' in this tribe, with all other extant members being removed to Microtini. List of species Tribe Arvicolini *Genus '' Arvicola'' - water voles ** European (or Northern) water vole, ''Arvicola amphibius (Arvicola terrestris)'' ** Southwestern (or Southern) water vole, ''Arvicola sapidus'' ** Montane water vole, ''Arvicola scherman'' Fossil genera *Genus '' Mimomys'' - Plio-Pleistocene The Plio-Pleistocene is an informally described geological pseudo-period, which begins about 5 million years ago (Mya) and, drawing forward, combines the time ranges of the formally defined Pliocene and Pleistocene epochs—marking from about 5&n ...

Ellobiusini
Ellobiusini is a tribe (taxonomy), tribe of voles containing two genera: ''Ellobius'' and ''Bramus''. All extant taxon, extant taxa in this tribe were formerly included in the genus ''Ellobius''. These species are distinguishable from most other voles in that they are highly fossorial, resembling the blesmols and spalacids more than other voles. The long-clawed mole vole is unrelated to these species. The nomenclature of this tribe is unresolved but may be changed to Bramina. "Ellobiusini" may be preoccupied by a tribe of snails in the family Ellobiidae. References Mammal tribes Taxa named by Theodore Gill Voles and lemmings Taxa described in 1872 {{Arvicolinae-stub ...

Lemming
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 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 occurrence in their habi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muskrat
The muskrat or common muskrat (''Ondatra zibethicus'') is a medium-sized semiaquatic rodent native to North America and an introduced species in parts of Europe, Asia, and South America. The muskrat is found in wetlands over various climates and habitats. It has crucial effects on the ecology of wetlands, and is a resource of food and fur for humans. Adult muskrats weigh , with a body length (excluding the tail) of . They are covered with short, thick fur of medium to dark brown color. Their long tails, covered with scales rather than hair, are laterally compressed and generate a small amount of thrust, with their webbed hind feet being the main means of Aquatic locomotion, propulsion, and the unique tail mainly important in directional stability. Muskrats spend most of their time in the water and can swim underwater for 12 to 17 minutes. They live in families of a male and female pair and their young. They build nests to protect themselves from the cold and predators, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mole (animal)
Moles are small, fossorial, subterranean mammals. They have cylindrical bodies, velvety fur, very small, inconspicuous eyes and ears, reduced hindlimbs, and short, powerful forelimbs with large paws adapted for digging. The word "mole" most commonly refers to many species in the family Talpidae (which are named after the Latin word for mole, ''talpa''). True moles are found in most parts of North America, Europe (except for Ireland) and Asia. Other mammals referred to as moles include the African Golden mole, golden moles and the Australian Marsupial mole, marsupial moles, which have a similar ecology and lifestyle to true moles but are unrelated. Moles may be viewed as pests to gardeners, but they provide positive contributions to soil, gardens, and ecosystems, including soil aeration, feeding on slugs and small creatures that eat plant roots, and providing prey for other wildlife. They eat earthworms and other small invertebrates in the soil. Terminology In Middle English, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
