The average eastern meadow vole lifespan is less than one month because of high nestling and juvenile mortality. [8] The average time adults are recapturable in a given habitat is about two months, suggesting the average extended lifespan (i.e. how much time adult eastern meadow voles have left) is about two months, not figuring in emigration.

The western meadow vole (Microtus drummondii) is a species of North American vole found in western North America, the midwestern United States, western Ontario, Canada, and formerly in Mexico. It was previously considered conspecific with the eastern meadow vole ( M. pennsylvanicus ), but genetic studies indicate that it is a distinct species.
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.
Slightly larger than moles, voles are 5 to 8 inches long and resemble field mice with short tails, compact heavy bodies, small eyes, and partially hidden ears, says Smith.
Another species from the same genus, the meadow vole, has promiscuously mating males, and scientists have changed adult male meadow voles' behavior to resemble that of prairie voles in experiments in which a viral vector was used to increase a single gene's expression within a particular brain region.

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.
The most convenient distinguishing feature of the Arvicolinae is the nature of their molar teeth, which have prismatic cusps in the shape of alternating triangles. These molars are an adaptation to a herbivorous diet in which the major food plants include a large proportion of abrasive materials such as phytoliths; the teeth get worn down by abrasion throughout the adult life of the animal and ...
The Cricetidae are a family of rodents in the large and complex superfamily Muroidea.It includes true hamsters, voles, lemmings, muskrats, and New World rats and mice.At over 870 species, it is either the largest or second-largest family of mammals, and has members throughout the Americas, Europe and Asia.
