Daurian Pika
The Daurian pika (''Ochotona dauurica'') is a small relative of rabbits and hares in the order Lagomorpha. It is well known for its “barking” alarm call, and for its peculiar habit of making hay to help survive the winter. There are 4 recognized subspecies, ''Ochotona dauurica annectens, O.d. bedfordi, O.d. dauurica, ''and'' O.d. mursavi''. Daurian pikas, like other lagomorphs, are characterized by a secondary set of incisor teeth. They are Sex#Sexual monomorphism, sexually monomorphic, with thick reddish coats. Pikas have no external tail, and their ears are large and rounded. The auditory bullae, a feature of the skull of daurian pikas are small in comparison to many other pikas. This is thought to be related to their fairly low altitude habitat preference. They are considered keystone species within their habitat. Range and habitat Daurian pikas are found throughout Mongolia, southern Russia, Manchuria and in several provinces of China. They live in mountainous regions, ...

Ochotona Dauurica, Tariat Sum, Arkhangai Province, Mongolia Extr
A pika ( , or ) is a small, mountain-dwelling mammal native to Asia and North America. With short limbs, a very round body, an even coat of fur, and no external tail, they resemble their close relative the rabbit, but with short, rounded ears. The large-eared pika of the Himalayas and nearby mountains lives at elevations of more than . The name ''pika'' appears to be derived from the Tungus ''pika'', and the scientific name ''Ochotona'' is derived from the Mongolian word ''ogotno, оготно'', which means pika. It is used for any member of the Ochotonidae (), a family within the order of lagomorphs, the order which also includes the Leporidae (rabbits and hares). They are the smallest animal in the lagomorph group. Only one genus, ''Ochotona'' ( or ), is extant within the family, covering 37 species, though many fossil genera are known. Another species, the Sardinian pika, belonging to the separate genus ''Prolagus'', has become extinct within the last 2,000 years owing to ...

Lagomorpha
The lagomorphs () are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae (rabbits and hares) and the Ochotonidae ( pikas). There are 110 recent species of lagomorph, of which 109 species in twelve genera are extant, including ten genera of rabbits (42 species); one genus of hare (33 species) and one genus of pika (34 species). The name of the order is derived from the Ancient Greek (, "hare") + (, "form"). Taxonomy and evolutionary history Other names used for this order, now considered synonymous, include: ''Duplicidentata'' (Illiger, 1811); ''Leporida'' (Averianov, 1999); ''Neolagomorpha'' (Averianov, 1999); ''Ochotonida'' (Averianov, 1999); and ''Palarodentia'' (Haeckel, 1895; Lilian, 2016). The evolutionary history of the lagomorphs is still not well understood. In the late 20th century, it was generally agreed that '' Eurymylus'', which lived in eastern Asia and dates back to the late Paleocene or early Eocene, was a ...

Mongolia
Mongolia is a landlocked country in East Asia, bordered by Russia to the north and China to the south and southeast.

Manchuria
Manchuria is a historical region in northeast Asia encompassing the entirety of present-day northeast China and parts of the modern-day Russian Far East south of the Uda (Khabarovsk Krai), Uda River and the Tukuringra-Dzhagdy Ranges. The exact geographical extent varies depending on the definition: in the narrow sense, the area constituted by three Chinese provinces of Heilongjiang, Jilin, and Liaoning as well as the eastern Inner Mongolian prefectures of China, prefectures of Hulunbuir, Hinggan League, Hinggan, Tongliao, and Chifeng; in a broader sense, historical Manchuria includes those regions plus the Amur river basin, parts of which were ceded to the Russian Empire by the Manchu-led Qing dynasty during the Amur Annexation of 1858–1860. The parts of Manchuria ceded to Russia are collectively known as Outer Manchuria or Russian Manchuria, which include present-day Amur Oblast, Primorsky Krai, the Jewish Autonomous Oblast, the southern part of Khabarovsk Krai, and the easter ...

Campbell's Dwarf Hamster
Campbell's dwarf hamster (''Phodopus campbelli'') is a species of hamster in the genus '' Phodopus''. It was given its common name by Oldfield Thomas in honor of Charles William Campbell, who collected the first specimen in Mongolia on July 1, 1902. It is distinguished from the closely related Djungarian hamster as it has smaller ears and no dark fur on its crown. Campbell's dwarf hamster typically has a narrow dorsal stripe compared to the Djungarian hamster and brown or gray fur on the stomach. This hamster may be raised in captivity and kept as a small pet. In the wild, the breeding season for Campbell's dwarf hamster varies by location. For example, the breeding season begins towards the middle of April in Tuva and towards the end of April in Mongolia. However, there is no fixed breeding season in captivity, and they can breed frequently throughout the year. Females are usually sexually mature at two months, and the gestation period is typically 20 days. Campbell's dwarf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammals Described In 1776
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the larg ...

Taxa Named By Peter Simon Pallas
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later stil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
