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 ...

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 ...

Microtini
Microtini is a tribe of voles in the subfamily Arvicolinae. Most members of this tribe were once placed in Arvicolini, but a 2021 study found that '' Arvicola'' is distinct from the other extant genera in Arvicolini, instead being sister to the tribe Lagurini. The current species listing of the American Society of Mammalogists lists only ''Arvicola'' in Arvicolini, with all other extant members being removed to Microtini.

Voles
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 molar (tooth), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lagurini
Lagurini is a tribe of lemmings in the subfamily Arvicolinae. It contains three species in two genera. Species in this tribe are known as steppe lemmings. It contains the following species: * Genus '' Eolagurus'' ** Yellow steppe lemming, ''E. luteus'' ** Przewalski's steppe lemming, ''E. przewalskii'' * Genus '' Lagurus'' ** Steppe lemming, ''L. lagurus'' Phylogenetic evidence based on mtDNA supports the water voles of the genus '' Arvicola'' not in fact belonging to the tribe Arvicolini, but rather forming a sister group to the Lagurini. Based on the study, the Lagurini and ''Arvicola'' together form a sister group to a clade comprising '' Hyperacrius'' and the rest of the Arvicolini Arvicolini is a tribe of voles in the subfamily Arvicolinae.

Arvicola
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 , tail lengths are , and their weights are . The animals may exhibit indeterminate growth. They are thick-furred and have hairy fringes on their feet that improve their swimming ability. A 2021 phylogenetic study using mtDNA found that ''Arvicola'' may not belong with the rest of its namesake tribe Arvicolini, but rather forms a sister group to the tribe Lagurini. Species There are three species as listed by the IUCN: * European (or northern) water vole (''A. amphibius'' or ''A. terrestris'') * Southwestern (or southern) water vole (''A. sapidus'') * Montane water vole (''A. scherman'') The American Society of Mammalogists Th ...

Mimomys
''Mimomys'' is an extinct genus of voles that lived in Eurasia and North America during the Plio-Pleistocene. It is believed that one of the many species belonging to this genus gave rise to the modern water voles ''(Arvicola)''. Several other prehistoric genera of vole are probably synonymous with ''Mimomys'', including the North American ''Cosomys'' and ''Ophiomys''. Several species are known to have survived into the Late Pleistocene, including ''M. pyrenaicus'' of France and ''M. chandolensis'' of the Russian Far East The Russian Far East ( rus, Дальний Восток России, p=ˈdalʲnʲɪj vɐˈstok rɐˈsʲiɪ) is a region in North Asia. It is the easternmost part of Russia and the Asia, Asian continent, and is coextensive with the Far Easte ..., which may have survived as recently as 50,000 BP.

Arvicola Sapidus
The southwestern water vole or southern water vole (''Arvicola sapidus'') is a large amphibious vole native to most of France and southwestwards through Spain and Portugal. It is listed on the IUCN Red List as Vulnerable species, vulnerable. Reproductive cycle The reproductive cycle of the southwestern water vole varies seasonally and geographically, with the most intense reproductive activity occurring from March through October, peaking between April and June. Although reproduction occurs year-round, a distinct reduction in reproductive activity occurs from November through February, coinciding with lower temperatures and shorter day lengths. Females become sexual maturity, sexually mature when they reach a weight of around 140 grams, with larger individuals typically having higher reproductive success. On average, females produce litters of about four offspring (range 1–7). Litter size is directly correlated with maternal body weight, with heavier females tending to have ...

John Edward Gray
John Edward Gray (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Society Of Mammalogists
The American Society of Mammalogists (ASM) was founded in 1919. Its primary purpose is to encourage the study of mammal A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three ...s, and professions studying them. There are over 4,500 members of this society, and they are primarily professional scientists who emphasize the importance of public policy and education. There are several ASM meetings held each year, and the society manages several publications such as the '' Journal of Mammalogy'', ''Special Publications'', '' Mammalian Species'', and ''Society Pamphlets''. The best known of these is the ''Journal of Mammalogy''. The ASM also maintains ''The Mammal Image Library'' which contains more than 1,300 mammal slides.

European Water Vole
The European water vole (''Arvicola amphibius'') or northern water vole is a semi-aquatic rodent. It is often informally called the water rat, though it only superficially resembles a true rat. Water voles have rounder noses than rats, deep brown fur, chubby faces and short fuzzy ears; unlike rats their tails, paws and ears are covered with hair. In the wild, on average, water voles only live about five months. Maximum longevity in captivity is two and a half years. Appearance Water voles reach in length, plus a tail which is about half the length of the body. Weights reported for adults are variable. It is possible for large, optimal adults to weigh as much as However, these are peak weights. Elsewhere, the mean body mass has been reported as , although this figure includes immature water voles. The minimum weight to successfully breed as well as to survive winter is reportedly in females and in males.Yavuz, Güliz, Ercüment Çolak, and Teoman Kankılıç. ''Investiga ...
