Middendorf's Vole
Middendorf's vole (''Microtus middendorffi'') is a species of rodent in the family Cricetidae. It is found only in Russia, most commonly north Siberia. The common name commemorates Alexander Theodor von Middendorff (1815–1894), a German–Russian naturalist who traveled extensively in Siberia. It is also known as the north Siberian vole or Altai vole. This vole, along with '' Microtus gregalis'', is one of the primary preys of the Arctic fox on the Yamal Peninsula The Yamal Peninsula (russian: полуостров Ямал, poluostrov Yamal) is located in the Yamalo-Nenets Autonomous Okrug of northwest Siberia, Russia.

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, 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/richochetal (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 mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, wh ...

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] |
Russia
Russia (, , ), or the Russian Federation, is a transcontinental country spanning Eastern Europe and Northern Asia. It is the largest country in the world, with its internationally recognised territory covering , and encompassing one-eighth of Earth's inhabitable landmass. Russia extends across eleven time zones and shares land boundaries with fourteen countries, more than any other country but China. It is the world's ninth-most populous country and Europe's most populous country, with a population of 146 million people. The country's capital and largest city is Moscow, the largest city entirely within Europe. Saint Petersburg is Russia's cultural centre and second-largest city. Other major urban areas include Novosibirsk, Yekaterinburg, Nizhny Novgorod, and Kazan. The East Slavs emerged as a recognisable group in Europe between the 3rd and 8th centuries CE.

Alexander Von Middendorff
Alexander Theodor von Middendorff (russian: Алекса́ндр Фёдорович Ми́ддендорф; tr. ; 18 August 1815 – 24 January 1894) was a zoologist and explorer of Baltic German and Estonian extraction. He is known for his expedition 1843–45 to the extreme north and east of Siberia, describing the effects of permafrost on the spread of animals and plants. Early life Middendorff's mother Sophia Johanson (1782–1868), the daughter of an Estonian farmer, had been sent to Saint Petersburg for education by her parents. There she met with the future director of the St. Petersburg Pedagogical Institute, Theodor Johann von Middendorff (1776–1856), whose father was a Baltic German pastor in Karuse, Estonia. As the two young people came from different social ranks and were unable to marry each other, their daughter Anette (b. 1809) and son Alexander were born out of wedlock. Alexander was born on 18 August 1815 in St. Petersburg, but could not be baptized unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microtus Gregalis
The narrow-headed vole (''Microtus gregalis'') is a species of rodent in the family Cricetidae. Ranging over northern and central Asia and also into Alaska, it is the only species in the subgenus ''Stenocranius''. Description The narrow-headed vole has a head-and-body length between and a short tail of . The dimensions of the skull distinguishes it from other ''Microtus'' species in China. In summer, the fur on the back is pale yellowish-buff, paler on the flanks and merging into the yellowish-grey underparts. In winter, the dorsal colour is a brighter reddish-ochre. The tail can either be a uniform yellowish-buff or can be bicoloured, dark brown above and yellowish-brown below. The upper surfaces of the hands and feet are brownish-white. Distribution and habitat The narrow-headed vole is distributed across the tundra region of northern Asia from the White Sea to the Kolyma River. It also occurs as separate populations on the steppes of Kazakhstan, Kyrgyzstan, southwestern Sibe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Fox
The Arctic fox (''Vulpes lagopus''), also known as the white fox, polar fox, or snow fox, is a small fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. It has a large and very fluffy tail. In the wild, most individuals do not live past their first year but some exceptional ones survive up to 11 years. Its body length ranges from , with a generally rounded body shape to minimize the escape of body heat. The Arctic fox preys on many small creatures such as lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds. It also eats carrion, berries, seaweed, and insects and other small invertebrates. Arctic foxes form monogamous pairs during the breeding season and they stay together to raise their young in complex underground dens. Occasionally, other family members may assist in raising thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamal Peninsula
The Yamal Peninsula (russian: полуостров Ямал, poluostrov Yamal) is located in the Yamalo-Nenets Autonomous Okrug of northwest Siberia, Russia. It extends roughly 700 km (435 mi) and is bordered principally by the Kara Sea, Baydaratskaya Bay on the west, and by the Gulf of Ob on the east. At the northern end of this peninsula lie the Malygina Strait and, beyond it, Bely Island. Across the river lies the Gyda Peninsula. In the language of its indigenous inhabitants, the Nenets, "Yamal" means "End of the Land". The Yamal peninsula is inhabited by a multitude of migratory bird species. The well-preserved remains of Lyuba, a 37,000-year-old mammoth calf, were found by a reindeer herder on the peninsula in the summer of 2007. The animal was female and was determined to be one month old at the time of death. Geography The peninsula consists mostly of permafrost ground and there are numerous lakes of thermokarst origin, the biggest of which are Neito a ...

Mammals Described In 1881
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wi ...
