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 alternating ...

Townsend's Vole
Townsend's vole (''Microtus townsendii'') is a species of rodent in the family Cricetidae, the sister species of '' M. canicaudus''. It is found in temperate grasslands of British Columbia in Canada and in the states of Washington and Oregon in the United States. Greek root words for "small ear" are the source for the genus name ''Microtus''. American naturalist and writer John Kirk Townsend collected the type specimen in 1835, which accounts for the second part of the name. Description Townsend's vole is one of the largest voles in North America, growing to a total length of including a tail of , and a weight of . The ears are wide and prominent, being clearly visible above the fur, which is thin and coarse. The upper surface is dark brown with many guard hairs with black tips and the underparts are paler. The feet are slate grey and the tail is blackish above and dark brown beneath. Juveniles are generally darker than adults with dark grey underparts and black tails and feet. ...

Creeping Vole
The creeping vole (''Microtus oregoni''), sometimes known as the Oregon meadow mouse, is a small rodent in the family Cricetidae. Ranging across the Pacific Northwest of North America, it is found in forests, grasslands, woodlands, and chaparral environments. The small-tailed, furry, brownish-gray mammal was first described in the scientific literature in 1839, from a specimen collected near the mouth of the Columbia River. The smallest vole in its range, it weighs around . At birth, they weigh , are naked, pink, unable to open their eyes, and the ear flaps completely cover the ear openings. Although not always common throughout their range, there are no major concerns for their survival as a species. Taxonomy The animal was described in 1839 by John Bachman. The original scientific name was ''Arvicola oregoni'' with a common name of the Oregon meadow mouse. The type specimen was an older male collected November 2, 1836 near the mouth of the Columbia River in Oregon. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microtus Townsendii
Townsend's vole (''Microtus townsendii'') is a species of rodent in the family Cricetidae, the sister species of '' M. canicaudus''.

Microtus Drummondii
The western meadow vole (''Microtus drummondii'') is a species of North American vole found in midwestern and western Canada and the United States, and formerly in Mexico. It was formerly considered conspecific with the eastern meadow vole (''M. pennsylvanicus''), but genetic studies indicate that it is a distinct species. Distribution It ranges from Ontario west to Alaska, and south to Missouri, north-central Nebraska, the northern half of Wyoming, and central Washington to Alaska; south through Idaho into north-central Utah. A disjunct subset of its range occurs from central Colorado to northwestern New Mexico. An isolated population was formerly found in Chihuahua, Mexico, but has since been extirpated. The United States portion of the Souris River is alternately known as the Mouse River because of the large numbers of field mice that lived along its banks. Plant communities In eastern Washington and northern Idaho, meadow voles are found in relative abundance in sedge ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern Meadow Vole
The eastern meadow vole (''Microtus pennsylvanicus''), sometimes called the field mouse or meadow mouse, is a North American vole found in eastern Canada and the United States. Its range extends farther south along the Atlantic coast. The western meadow vole, Florida salt marsh vole, and beach vole were formerly considered regional variants or subspecies of M. pennsylvanicus, but have all since been designated as distinct species. The eastern meadow vole is active year-round, usually at night. It also digs burrows, where it stores food for the winter and females give birth to their young. Although these animals tend to live close together, they are aggressive towards one another. This is particularly evident in males during the breeding season. They can cause damage to fruit trees, garden plants, and commercial grain crops. Taxonomy The species was formerly grouped with the western meadow vole (''M. drummondii'') and the Florida salt marsh vole (''M. dukecampbelli'') as a ...

Montane Vole
The montane vole (''Microtus montanus'') is a species of vole native to the western United States and Canada. Description Montane voles are medium-sized voles, with a total length of , including the tail. Adults typically weigh anything from , with males being slightly larger than females, but the actual weight varies considerably with age, geography, and subspecies. The upper body is covered with fur of a dark brownish shade, again with some variation between individuals. The fur is paler on the flanks, and fades to grey or white on the underparts. The tail exhibits the same color variation, with the fur being dark brown to almost black on the upper surface and grey or white below. Montane voles possess scent glands on the hips, near the anus, and on the male genitalia. These glands increase in size in response to testosterone, and are therefore particularly large in adult males. At least some of these glands produce unique fatty acid esters, that may function in species recogn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Florida Salt Marsh Vole
The Florida salt marsh vole (''Microtus dukecampbelli'') is a North American vole endemic to the state of Florida in the United States. Taxonomy It was formerly thought conspecific with the eastern meadow vole (''M. pennsylvanicus''), but more recent genetic studies indicate that it is basal to both the eastern and western (''M. drummondii'') meadow voles, and thus represents a distinct species. Distribution According to fossil and subfossil material, the Florida salt marsh vole formerly had a wide range throughout the southeastern United States, but by 5,000 years before the present, due to climatic changes prompting a transition from grassland to forest habitats, it became an uncommon species restricted to Florida. It is now restricted to just a single salt marsh in Waccasassa Bay in Levy County. Habitat It is found in a transitional high salt marsh, near the edges of patches of ''Juncus roemerianus'' in patches of ''Distichlis spicata''. It appears to avoid areas domi ...

Microtus
''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. About 62 species are placed in the genus. 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".

Gray-tailed Vole
The gray-tailed vole (''Microtus canicaudus'') also known as the gray-tailed meadow vole or gray-tailed meadow mouse, is a rodent in the genus ''Microtus'' (small-eared "meadow voles") of the family Cricetidae. Voles are small mammals, and this species lies roughly in the middle of their size range. First collected in 1895, it is endemic to the Willamette Valley, Oregon, and Clark County, Washington, in the Pacific Northwest region of North America. Historically, they were found in the prairie areas of the Valley and, though many of these areas have been converted for agricultural purposes, these animals remain common. For reasons that remain unclear, vole population densities in any area may fluctuate widely from season to season and year to year. They are preyed upon by owls, hawks, and carnivorous mammals, and their parasites include fleas and ticks. These voles build burrows and complex tunnel networks, which they sometimes share with other burrowing animals. Relatively littl ...
