Description The long-tailed ground squirrel has a compact, low-slung body, short legs and a long bushy tail. The body length reaches up to and the tail . The back is brown with a linear pattern of dark, small spots. The underparts are a paler ochre-brown with a reddish tinge along the side.

Peter Simon Pallas
Peter Simon Pallas FRS FRSE (22 September 1741 – 8 September 1811) was a Prussian zoologist and botanist who worked in Russia between 1767 and 1810. Life and work Peter Simon Pallas was born in Berlin, the son of Professor of Surgery Simon Pallas. He studied with private tutors and took an interest in natural history, later attending the University of Halle and the University of Göttingen. In 1760, he moved to the University of Leiden and passed his doctor's degree at the age of 19. Pallas travelled throughout the Netherlands and to London, improving his medical and surgical knowledge. He then settled at The Hague, and his new system of animal classification was praised by Georges Cuvier. Pallas wrote ''Miscellanea Zoologica'' (1766), which included descriptions of several vertebrates new to science which he had discovered in the Dutch museum collections. A planned voyage to southern Africa and the East Indies fell through when his father recalled him to Berlin. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sakha, officially the Republic of Sakha (Yakutia),, is the largest republic of Russia, located in the Russian Far East, along the Arctic Ocean, with a population of roughly 1 million. Sakha comprises half of the area of its governing Far Eastern Federal District, and is the world's largest country subdivision, covering over 3,083,523 square kilometers (1,190,555 sq mi).

It is pronounced as ''Haka'' by the Dolgans, whose language is either a dialect or a close relative of the Yakut language.Victor P. Krivonogov, "The Dolgans’Ethnic Identity and Language Processes."

Mammals Described In 1778
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 wit ...

One of the species listed for Russia is extinct and one can no longer be found in the wild. All the mammals of Russia are in the subclass Theria and infraclass Eutheria, being all Placentalia, placental. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: Order: Sirenia (manatees and dugongs) Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered. *Family: Dugongidae **Genus: ''Hydrodamalis'' ***Steller's sea cow, ''H. gigas'' Order: Rodentia (rodents) Rodents make up the largest order of mammals, with over 40% of mammalian species.

Mammals Of Mongolia
This is a list of the naturally occurring mammal species recorded in Mongolia. There are 121 mammal species in Mongolia, of which two are critically endangered, four are endangered, nine are vulnerable, and six are near threatened. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of near threatened and least concern categories: Order: Artiodactyla (even-toed ungulates) ---- The even-toed ungulates are ungulates whose weight is borne about equally by the third and fourth toes, rather than mostly or entirely by the third as in perissodactyls. There are about 220 artiodactyl species, including many that are of great economic importance to humans. *Family: Bovidae (cattle, antelope, sheep, goats) **Subfamily: Antilopinae ***Genus: ''Gazella'' **** Goitered gazelle, ''G ...

Rodents Of China
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, whose incisors ...

Urocitellus
''Urocitellus'' is a genus of ground squirrels. They were previously believed to belong to the much larger genus '' Spermophilus'', but DNA sequencing of the cytochrome ''b'' gene showed that this group was paraphyletic to the prairie dogs and marmots, and could therefore no longer be retained as a single genus. As a result, ''Urocitellus'' is now considered as a genus in its own right. All but two species are native to the northern and western parts of North America, from California and Minnesota through the north-western United States and western Canada; the Arctic ground squirrel inhabits Arctic terrain on both sides of the Bering Strait, while the long-tailed ground squirrel is exclusively found in Asia. The name of the genus is said to be derived from the Latin ''uro'', meaning "tail" and ''citellus'' for "ground squirrel". The proper word for "tail" in classical Latin is ''cauda''.Lewis, C.T. & Short, C. (1879). ''A Latin dictionary founded on Andrews' edition of Freund' ...

Amur River
The Amur (russian: река́ Аму́р, ), or Heilong Jiang (, "Black Dragon River", ), is the world's tenth longest river, forming the border between the Russian Far East and Northeastern China (Inner Manchuria). The Amur proper is long, and has a drainage basin of . ''mizu'' ("water") in Japanese. The name "Amur" may have evolved from a root word for water, coupled with a size modifier for "Big Water". Its ancient Chinese names were ''Yushui'', ''Wanshui'' and ''Heishui'', formed from variants to ''shui'', meaning "water".The fishes of the Amur River:updated check-list and zoogeography'' The modern Chinese name for the river, ''Heilong Jiang'' means "Black Dragon River", while the Manchurian name ''Sahaliyan Ula'', the Mongolian names " Amar mörön " (Cyrillic: Амар мөрөн) originates from the name " Amar " meaning to rest and ''Khar mörön'' (Cyrillic: Хар мөрөн) mean Black River.

Eastern Siberia
Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over , but home to merely one-fifth of Russia's population. Novosibirsk, Krasnoyarsk and Omsk are the largest cities in the region. Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of north-ce ...
