Microtus Maximowiczii
Maximowicz's vole (''Alexandromys maximowiczii'') is a species of rodent in the family Cricetidae. It is found in northeastern China, Mongolia, and eastern Russia. Description Maximowicz's vole is one of the largest voles in the genus '' Alexandromys''. Adults grow to a head-and-body length of with a tail length of . The fur on the back is dark brownish-black with ochre specks, and the flanks are paler brown, blending gradually into the greyish-white underparts. The upper sides of the hands and feet are whitish-brown. The tail is either uniform dark brown or bicoloured, with the upper side dark brown and the underside white. Its scientific and common names commemorate the prominent Russian botanist Karl Maximovich, who was curator of the herbarium at the Saint Petersburg Botanical Garden at the time the vole was described by Leopold von Schrenck. Distribution and habitat Maximowicz's vole is found in eastern Asia. Its range extends from Lake Baikal eastward to the mountains of ...

Leopold Von Schrenck
Peter Leopold von Schrenck (; 1826 – 8 January 1894) was a Russian zoologist, geographer and ethnographer. Biography Schrenck came from a Baltic German family, and was born and raised in the , Sumsky Uyezd, Kharkov Governorate. He received his doctorate from the Imperial University of Dorpat, and then studied natural science in Berlin and Königsberg. He joined the crew of the ''Aurora'' (Russian Imperial Navy frigate) in the circumnavigation of the world. In 1853 Schrenck was sent by the St Petersburg Academy of Sciences to explore the Amurland on board the schooner ''Vostok''. He reached the mouth of the Amur in September 1854 with the botanist Carl Maximowicz. In February 1855 he visited Sakhalin and then explored the Amur in the spring and summer. In 1856 he returned overland to Europe, via Lake Baykal. He published his findings in his ''Reisen und Forschungen im Amur-Lande in den Jahren 1854-56'', in two quarto volumes, 1858–60, with more than 350 pages on bir ...

Rodent
Rodents (from Latin , '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 share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

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 over 870 species, it is either the largest or 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 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
