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 ...

Montane Water Vole
The Montane water vole (''Arvicola scherman'') is a fossorial species of vole found throughout Central and Western Europe, northern Spain, and central Romania, particularly in high-altitude mountain regions such as the Alps, Pyrenees, and Carpathians. ''Arvicola scherman'' was initially regarded as a subspecies of ''Arvicola terrestris'' but was later redesignated as a species by Panteleyev in 2000. Unlike its close relative, the European water vole (''Arvicola amphibius''), which is semi-aquatic, the Montane water vole has adapted to a burrowing lifestyle in mountainous environments. Genetic and fossil evidence suggest that the ''Arvicola'' species originated during the Pleistocene epoch, with the Montane water vole diverging due to habitat specialization and geographic isolation. While the American Society of Mammalogists treats ''A. scherman'' as a synonym of ''Arvicola amphibius'', genetic studies indicate distinct differences between the two species.

Persian 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. ''Investigat ...

Southwestern Water Vole
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. 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 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 larger litters.

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.

Water Vole (North America)
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 American ''Microtus'' species. Water voles are on the USDA Forest Service Region 2 sensitive species list because they maintain very small populations and there is high concern that their required habitat may be declining. These animals have gray-brown or red-brown fur with gray under parts. Their large hind feet help make them excellent swimmers, and they are found in alpine or semi-alpine meadows near water. They feed on grasses, leaves, roots and seeds, also eating small invertebrates. Water voles dig burrows that are connected to water sources, and are considered a semi-aquatic species. They are active year-round, tunneling through ... [...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. 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 So ....

Rodent Genera

Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area aroun ... , '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 shar ...

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] |
