Microtus Oaxacensis
''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". There is some disagreement on the definitive list of species in this genus, and which subgenera are recognized. The American Society of Mammalogists recognizes the following 60 species, with discrepancies as noted: Subgenus ''Blanfordimys'' * Afghan vole (''Microtus afghanus'') * Bucharian vole (''Microtus bucharensis'') * Juniper vole (''Microtus yuldaschi'') Subgenus ''Euarvicola'' * Short-tailed field vole (''Microtus agrestis'') * Mediterranean field vole (''Microtus lavernedii'') * Portuguese field vole (''Microtus rozianus'') Subgenus ''Hyrcanicola'' (not recognized by the ASM, listed in subgenus ''Microtus'') * Schelkovni ...

Microtus Quasiater
The Jalapan pine vole (''Microtus quasiater'') is a species of rodent in the family Cricetidae, found only in Mexico. The scientific name ''quasiater'' translates as "almost black", while the common name refers to the city of Jalapa, close to where the first specimen was collected. Description The Jalapan pine vole is the smallest species of vole found in Mexico, with an adult body length of and an average weight of . The fur is long, soft, and dark brown in color, becoming paler on the underparts. There is no significant difference in size between males and females.

Microtus Pinetorum
The woodland vole (''Microtus pinetorum'') is a small vole found in Eastern United States, eastern North America. It is also known as the pine vole. Characteristics The woodland vole has a head and body length ranging between with a short tail. Its weight ranges between . It has a brown (light or dark) dorsal region with a whitish or silvery underside. The eyes, external ears and tail are reduced to adapt to their partially subterranean lifestyle. Ecology The woodland vole lives throughout the eastern United States, ranging as far as Nebraska, Kansas, Oklahoma, and Texas. They inhabit deciduous forests, dry fields, and apple orchards. Voles prefer wooded areas with high vertical vegetative stratification but also evergreen shrubs, ground cover, and old fallen logs. Deciduous forests with moist, friable soils are suitable for burrowing and voles are most abundant in these habitats. However, they can also be found in other habitats from dry fields to the edges of coastal bays.Whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microtus Guatemalensis
The Guatemalan vole (''Microtus guatemalensis'') is a species of rodent in the family Cricetidae. It is found in Guatemala and Chiapas, Mexico, in montane pine-oak forest and meadow at elevations between 2600 and 3100 m above sea level. It is terrestrial and probably diurnal or crepuscular In zoology, a crepuscular animal is one that is active primarily during the twilight period, being matutinal (active during dawn), vespertine (biology), vespertine/vespertinal (active during dusk), or both. This is distinguished from diurnalit ....

Tarabundí Vole
The Tarabundí vole (''Microtus oaxacensis''), a medium-large blackish brown vole, is a species of rodent in the family Cricetidae. It is found only in Mexico Mexico, officially the United Mexican States, is a country in North America. It is the northernmost country in Latin America, and borders the United States to the north, and Guatemala and Belize to the southeast; while having maritime boundar ..., originating from Tuxtepec, Oaxaca, one of the only other species from Oaxaca besides the Microtus mexicanus. The Microtus oaxacensis habitats themselves in disturbed vegetations that consist of different grasses and wild strawberries in cloud forest and pine forest, and often can be found living by the highway margins of Tuxtepec, where the cleaning of these vegetations by the highways put the vole at risk, making them vulnerable to extinction. Their habitats provide their diet of strawberry stems and leaves and most importantly, grass. References Jones, J. K., & Genoways, ...

Voles And Lemmings
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 ...

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] |
Fossorial
A fossorial animal () is one that is adapted to digging and which lives primarily (but not solely) underground. Examples of fossorial vertebrates are Mole (animal), moles, badgers, naked mole-rats, meerkats, armadillos, wombats, and mole salamanders. Among invertebrates, many molluscs (e.g., clams), insects (e.g., beetles, wasps, bees), and arachnids (e.g. spiders) are fossorial. Prehistoric evidence The physical adaptation of fossoriality is widely accepted as being widespread among many Prehistory, prehistoric Phylum, phyla and Taxon, taxa, such as bacteria and early eukaryotes. Furthermore, fossoriality has evolved independently multiple times, even within a single Family (biology), family. Fossorial animals appeared simultaneously with the colonization of land by arthropods in the late Ordovician period (over 440 million years ago). Other notable early burrowers include ''Eocaecilia'' and possibly ''Dinilysia''. The oldest example of burrowing in synapsids, the lineag ...
