Red-cheeked Ground Squirrel
The red-cheeked ground squirrel (''Spermophilus erythrogenys'') is a species of rodent in the family Sciuridae. It is commonly referred to as the red-cheeked ground souslik and there are several recognized subspecies. It is found in central Asia. ''Spermophilus brunnescens'' (Belyaev, 1943), ''Spermophilus heptneri'' (Vasil’eva, 1964) and ''Spermophilus ungae'' (Martino, 1923) are accepted as synonyms. There is some controversy over whether '' Spermophilus pallidicauda'' and '' Spermophilus brevicauda'' should be regarded as synonyms or full species. Characteristics The red-cheeked ground squirrel has a stout, low-slung body supported by short legs and a well-furred tail measuring about a third the length of the body. It has internal cheek pouches for carrying food. The head, neck and body are varying shades of grayish brown and there is a reddish-ochre patch on the bridge of the nose.

Johann Friedrich Von Brandt
Johann Friedrich von Brandt (25 May 1802 – 15 July 1879) was a German-Russian natural history, naturalist, who worked mostly in Russia. Brandt was born in Jüterbog and educated at a Gymnasium (school), gymnasium in Wittenberg and the Humboldt University of Berlin, University of Berlin. In 1831 he emigrated to Russia, and soon was appointed director of the Zoological Museum of the St Petersburg Academy of Sciences. Brandt encouraged the collection of native animals, many of which were not represented in the museum. Many specimens began to arrive from the expeditions of Nikolai Alekseevich Severtzov, Severtzov, Nikolai Przhevalsky, Przhevalsky, Aleksandr Fyodorovich Middendorf, Middendorff, Leopold von Schrenck, Schrenck and Gustav Radde. He described several birds collected by Russian explorers off the Pacific Coast of North America, including Brandt's cormorant, red-legged kittiwake and spectacled eider. As a paleontologist, Brandt ranks among the best. He was also an entomo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, whose i ...

Sciuridae
Squirrels are members of the family Sciuridae, a family that includes small or medium-size rodents. The squirrel family includes tree squirrels, ground squirrels (including chipmunks and prairie dogs, among others), and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and to the dormice. Etymology The word ''squirrel'', first attested in 1327, comes from the Anglo-Norman which is from the Old French , the reflex of a Latin word , which was taken from the Ancient Greek word (; from ) 'shadow-tailed', referring to the long bushy tail which many of its members have. The native Old English word for the squirrel, , survived only into Middle English (as ) before being replaced. The Old English word is of Common Germanic origin, cognat ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Spermophilus Pallidicauda
The pallid ground squirrel (''Spermophilus pallidicauda'') is a species of rodent in the family Sciuridae. It is found in Mongolia and the adjacent Nei Mongol autonomous region. A generic revision of the genus was undertaken in 2007 which helped resolve the uncertainty as to whether this species should be considered a subspecies of '' Spermophilus erythrogenys''. A phylogeny based on molecular sequence data determined that ''S. pallidicauda'' was indeed a separate species from ''S. erythrogenys'', and from the other similar species in the genus, ''S. brevicauda'' and ''S. alashanicus''. Distribution The pallid ground squirrel is found in Mongolia near Lake Khulu-Nur and the Baidarak River and in Ullyn Bulyk, the Mongolian and the Gobi Altai Mountains.

Spermophilus Brevicauda
''Spermophilus brevicauda'' (Brandt’s ground squirrel) is a species of rodent in the family Sciuridae. It is found in eastern Kazakhstan and the northern half of the Xinjiang region of China. A generic revision of the genus was undertaken in 2007 which helped resolve the uncertainty as to whether this species should be considered a subspecies of '' Spermophilus erythrogenys''. A phylogeny based on molecular sequence data determined that ''S. brevicauda'' was indeed a separate species from ''S. erythrogenys'', and from the other similar species in the genus, ''S. pallidicauda'' and ''S. alashanicus''. Distribution Brandt's ground squirrel is found from the Lake Zaysan region in eastern Kazakhstan, southwards and westwards along the Tian Shan mountain range to the vicinity of Almaty, on both sides of the Kazakh-Chinese border. The closely related species, '' Spermophilus alashanicus'' from the Alashan Desert and '' Spermophilus pallidicauda'', found in north east Gansu and Inn ...

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 ...
