East Siberian Lemming
The East Siberian lemming, Eastern Siberian brown lemming, or Ognev's lemming (''Lemmus paulus'') is a species of lemming endemic to Russia, where it has a disjunct distribution throughout parts of Siberia east of the Verkhoyansk Range. Taxonomy It was formerly thought conspecific with the West Siberian lemming (''L. sibiricus''), which replaces it west of the Verkhoyansk Range, with both species being previously classified together as the Siberian brown lemming. Some populations were also previously classified as populations of the Amur lemming (''L. amurensis''). More recent genetic studies found both the eastern ''L. sibiricus'' and the northern ''L. amurensis'' to together represent a distinct species from either species. The results of these studies were accepted by the American Society of Mammalogists. Distribution There are several disjunct populations; one is found from the Verkhoyansk Range east to the Kolyma River, including the New Siberian Islands; it is largely r ...

Wrangel Island
Wrangel Island ( rus, О́стров Вра́нгеля, r=Ostrov Vrangelya, p=ˈostrəf ˈvrangʲɪlʲə; ckt, Умӄиԓир, translit=Umqiḷir) is an island of the Chukotka Autonomous Okrug, Russia. It is the 91st largest island in the world and roughly the size of Crete. Located in the Arctic Ocean between the Chukchi Sea and East Siberian Sea, the island lies astride the 180th meridian. The International Date Line is therefore displaced eastwards at this latitude to avoid the island as well as the Chukchi Peninsula on the Russian mainland, to keep the island on the same day as the rest of Russia. The closest land to Wrangel Island is the tiny and rocky Herald Island located to the east.Kosko, M.K., M.P. Cecile, J.C. Harrison, V.G. Ganelin, N.V., Khandoshko, and B.G.

Beringian Lemming
The Beringian lemming or Beringian brown lemming (''Lemmus nigripes'') is a species of lemming found in Russia and North America. Taxonomy It was formerly considered conspecific with the Canadian lemming (''L. trimucronatus'') with both species being grouped together as the "North American brown lemming", but genetic studies have affirmed both as being distinct species from one another. Distribution This species is found on both sides of the Bering Sea, and its distribution roughly coincides with the former landmass of Beringia, which it likely inhabited prior to its partial submergence. In Siberia, it is found east of the Kolyma River (with the East Siberian lemming, ''L. paulus'', being found west of the river) ranging throughout most of Chukotka, northern Magadan, and northern Kamchatka Krai. A disjunct population is also present in the southern Kamchatka Peninsula, which is otherwise inhabited only by ''L. paulus''. In North America, it is found throughout most of ...

Rodents Of Asia
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 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 Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and ...

Endemic Fauna Of Russia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Siberia
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 ...

New Siberian Islands
The New Siberian Islands ( rus, Новосиби́рские Oстрова, r=Novosibirskiye Ostrova; sah, Саҥа Сибиир Aрыылара, translit=Saña Sibiir Arıılara) are an archipelago in the Extreme North of Russia, to the north of the East Siberian coast between the Laptev Sea and the East Siberian Sea north of the Sakha (Yakutia) Republic. History The first news about the existence of the New Siberian Islands was brought by a Cossack, Yakov Permyakov, in the beginning of the 18th century. In 1712, a Cossack unit led by M. Vagin reached the Great Lyakhovsky Island. In 1809–10 Yakov Sannikov and Matvei Gedenschtrom went to the New Siberian Islands on a cartographic expedition. Sannikov reported the sighting of a "new land" north of Kotelny in 1811. This became the myth of ''Zemlya Sannikova'' or ''Sannikov Land''.Markham, Albert Hastings ''Arctic Exploration'', 1895 In 1886, Russian polar explorer and scientist Eduard Toll, during his first visit to the New ...

Joel Asaph Allen
Joel Asaph Allen (July 19, 1838 – August 29, 1921) was an American zoology, zoologist, mammalogy, mammalogist, and ornithology, ornithologist. He became the first president of the American Ornithologists' Union, the first curator of birds and mammals at the American Museum of Natural History, and the first head of that museum's Department of Ornithology. He is remembered for Allen's rule, which states that the bodies of endotherms (warm-blooded animals) vary in shape with climate, having increased surface area in hot climates to lose heat, and minimized surface area in cold climates, to conserve heat. Early life Allen was born in Springfield, Massachusetts, the son of Joel Allen and Harriet Trumbull. He studied and collected specimen of natural history early in life, but he was forced to sell his relatively large collection so that he could attend the Wilbraham & Monson Academy in 1861. The following year, he transferred to Harvard University, where he studied under Louis Agassi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
