Grey Dwarf Hamster
The grey dwarf hamster, grey hamster or migratory hamster (''Cricetulus migratorius'') is a species of rodent in the family Cricetidae. Its range extends from Eastern Europe through the Middle East, Russia and Central Asia to Mongolia and western China. The grey dwarf hamster has grey fur and a head-body length ranging from . The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".

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] |
Moldova
Moldova ( , ; ), officially the Republic of Moldova ( ro, Republica Moldova), is a landlocked country in Eastern Europe. It is bordered by Romania to the west and Ukraine to the north, east, and south. The unrecognised state of Transnistria lies across the Dniester river on the country's eastern border with Ukraine. Moldova's capital and largest city is Chișinău. Most of Moldovan territory was a part of the Principality of Moldavia from the 14th century until 1812, when it was ceded to the Russian Empire by the Ottoman Empire (to which Moldavia was a vassal state) and became known as Bessarabia. In 1856, southern Bessarabia was returned to Moldavia, which three years later united with Wallachia to form Romania, but Russian rule was restored over the whole of the region in 1878. During the 1917 Russian Revolution, Bessarabia briefly became an autonomous state within the Russian Republic, known as the Moldavian Democratic Republic. In February 1918, the Moldavian D ...

Mammals Of Western Asia
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 with Sauropsid ...

Rodents Of Europe
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 inciso ...

Cricetulus
''Cricetulus'' is a genus of rodent in the family Cricetidae (voles and hamsters); it has seven member species that inhabit arid or semi-arid regions in Eurasia. They tend to be more ratlike in appearance than typical hamsters, hence the common name ''ratlike hamster''. Many of the species are considered dwarf hamsters. However, members of the genera ''Allocricetulus'', ''Tscherskia'', and ''Cansumys'' are often called ''ratlike hamsters'', and so are considered to be members of the genus ''Cricetulus'' by many authorities. Species *''Cricetulus alticola'' — Tibetan dwarf hamster *''Cricetulus barabensis'' — Chinese striped hamster *''Cricetulus griseus'' — Chinese hamster *''Cricetulus kamensis'' — Kam dwarf hamster *''Cricetulus lama'' — Lama dwarf hamster *''Cricetulus longicaudatus'' — long-tailed dwarf hamster *''Cricetulus migratorius'' — grey dwarf hamster *''Cricetulus sokolovi'' — Sokolov's dwarf hamster Sokolov's ...

House Mouse
The house mouse (''Mus musculus'') is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species of the genus ''Mus''. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity. The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. The complete mouse reference genome was sequenced in 2002. Characteristics House mice have an adult body length (nose to base of tail) of and a tail length of . The weight is typically . In the wild they vary in color from grey and light brown to black (individual hairs are actually agouti coloured), but domesticated fancy mice and laboratory mice ...

Hibernation
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months. Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and utilise similar mechanisms. The equivalent during the summer months is aestivation. Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months—depending on the species, ambient temperatu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pamir Mountains
The Pamir Mountains are a mountain range between Central Asia and Pakistan. It is located at a junction with other notable mountains, namely the Tian Shan, Karakoram, Kunlun, Hindu Kush and the Himalaya mountain ranges. They are among the world's highest mountains. Much of the Pamir Mountains lie in the Gorno-Badakhshan Province of Tajikistan. To the south, they border the Hindu Kush mountains along Afghanistan's Wakhan Corridor in Badakhshan Province, Chitral and Gilgit-Baltistan regions of Pakistan. To the north, they join the Tian Shan mountains along the Alay Valley of Kyrgyzstan. To the east, they extend to the range that includes China's Kongur Tagh, in the "Eastern Pamirs", separated by the Yarkand valley from the Kunlun Mountains. Name and etymology Since Victorian times, they have been known as the " Roof of the World", presumably a translation from Persian. Names In other languages they are called: ps, , ; ky, Памир тоолору, , ; fa, , R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
