Black-backed Shrew Mole
The black-backed shrew mole (''Uropsilus atronates'') is a species of mammal in the family Talpidae. It is endemic to China, where it is only known from the vicinity of Mucheng in Yunnan Province. It was first named as a subspecies of Anderson's shrew mole, ''Rhynchonax andersoni atronates'', by Glover Morrill Allen in 1923. Later it was considered synonymous with the gracile shrew mole (''U. gracilis''), but a 2018 phylogenetic study found it to be a distinct species. The study found it to be sister species to a clade comprising ''U. gracilis'' and a putative undescribed species of ''Uropsilus''. Both groups likely diverged during the early-mid Pleistocene The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.

Glover Morrill Allen
Glover Morrill Allen (February 8, 1879 – February 14, 1942) was an American zoologist. Born in Walpole, New Hampshire, the son of Reverend Nathaniel Glover Allen and Harriet Ann (Schouler) Allen, he studied at Harvard University. While still a student, Allen published ''The Birds of Massachusetts'' and ''A List of the Birds of New Hampshire''. After graduating in 1901, he was appointed librarian to the Boston Society of Natural History, and in 1904, obtained a Ph.D. from Harvard. From 1924, he lectured in zoology at Harvard and held the position of Curator of Mammals in the Museum of Comparative Zoology. He traveled widely, to Central and South America, to East and West Africa, the Nile, the Belgian Congo as a member of the eight-man Harvard Medical African Expedition (1926–1927), and Australia as a member of the six-man Harvard Australian Expedition (1931–1932) along with his student, Ralph Nicholson Ellis. His publications include: ''Bats: Biology, Behavior and Folklor ...

Gracile Shrew Mole
The gracile shrew mole (''Uropsilus gracilis'') is a species of mammal in the family Talpidae. It is endemic to China; populations known from Myanmar likely represent other species (see below). The black-backed shrew mole (''U. atronates'') and the Snow Mountain shrew mole (''U. nivatus'') were formerly considered subspecies, but a 2018 phylogenetic study split them as distinct species. The study found ''U. gracilis'' to be the sister species to an undescribed species of '' Uropsilus'', with the clade comprising both being sister to ''U. atronates''. ''U. atronates'' and the clade containing ''U. gracilis'' likely diverged during the early-mid Pleistocene The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.

Endemic Fauna Of Yunnan
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Mammals Of China
This is a list of the mammal species recorded in China. There are 495 mammal species in China, of which thirteen are critically endangered, twenty-four are endangered, forty-seven are vulnerable, and seven are near threatened. One of the species listed for China can no longer be found in the wild. 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: 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: ''Dugong'' ***Dugong, ''D. dugon'' Order: Proboscidea (elephants) The elephants comprise three living species and are the larges ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Uropsilus
The shrew moles or shrew-like moles (''Uropsilus'') are shrew-like members of Talpidae, the mole family of mammals endemic to the forested, high-alpine region bordering China, Myanmar, and Vietnam. They possess a long snout, a long slender tail, external ears, and small forefeet unspecialized for burrowing. Although they are similar to shrews in size, external appearance, and, presumably, ecological habits, they are nevertheless Talpidae, talpids and considered true mole (animal), moles, as they share a full zygomatic arch with all other moles, while this arch is completely absent in shrews. The genus is the only one of the subfamily Uropsilinae, which is one of the three main subfamilies of Talpidae, the other two being Talpinae, or Old World moles and relatives; and the Scalopinae, or New World moles. Although little is currently known regarding any aspect of their natural history, the Uropsilinae are thought to be the most ancestral group of moles, and as such, very similar t ...

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...

Mammal
A mammal () is a vertebrate animal of the Class (biology), 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 Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), 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, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...
