Imaizumi's Red-backed Vole

	Imaizumi's Red-backed Vole Imaizumi's red-backed vole (''Myodes imaizumii'') is a species of vole in the family Cricetidae 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 almost 608 species, it is the second-largest family of mammals, and h .... It is found in Japan and was initially designated as a subspecies of the Japanese red-backed vole, with studies of cranial and molar patterns supporting this. However, genetic tests in the late 1990s provide support for the theory that ''M. imaizumii'' is indeed a separate species, and it is now considered such pending the completion of more detailed studies.

	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 in North America. 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. A mating pair can produce a hundred more voles in a year. Voles outwardly resemble s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Cricetidae 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 almost 608 species, it is the second-largest family of mammals, and has members throughout the Americas, Europe and Asia. Characteristics The cricetids are small mammals, ranging from just in length and in weight in the New World pygmy mouse up to and in the muskrat. The length of their tails varies greatly in relation to their bodies, and they may be either furred or sparsely haired. The fur of most species is brownish in colour, often with a white underbelly, but many other patterns exist, especially in the cricetine and arvicoline subfamilies. Like the Old World mice, cricetids are adapted to a wide range of habitats, from the high Arctic to tropical rainforests and hot deserts. Some are arboreal, with long balancing tails and other adaptations for climbing, while others are semiaquatic, with w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Japanese Red-backed Vole The Japanese red-backed vole, Wakayama red-backed vole, or Anderson's red-backed vole (''Craseomys andersoni'') is a species of rodent in the family Cricetidae. It is found only on the island of Honshu in Japan. It was first described by the British zoologist Oldfield Thomas in 1905. Thomas named it in honor of scientific collector Malcolm Playfair Anderson. The International Union for Conservation of Nature lists it as "least concern". Distribution and habitat The Japanese red-backed vole is endemic to the island of Honshu in Japan and occurs in the Chūbu region, the Hokuriku region and in the more northerly parts of the island, and also in the Kii Peninsula. It is mostly found at altitudes of over but below the alpine zone Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets .... It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
