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.

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum, London, Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, 1st Baronet, Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker to rearrange the exhibitions, allowing Thomas to concentrate on these new specimens. Thomas viewed his taxonomy efforts from the scope of British impe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Undescribed Taxon
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a ''nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp.", but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this case, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mammals Described In 1911
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 Felidae, cats, Canidae, dogs, and Pinniped, seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 ...

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 ...

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 ...

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 ...

Snow Mountain Shrew Mole
The Snow Mountain shrew mole (''Uropsilus nivatus'') is a species of mammal in the family Talpidae. It is native to Yunnan Province in China and potentially Myanmar. Its common name references Jade Dragon Snow Mountain, which is the type locality of the species. Aside from there, the only other confirmed specimen is from Cang Mountain. It was formerly 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 the second most basal member of ''Uropsilus'' (with only the inquisitive shrew mole, ''U. investigator'', being more basal), diverging from the rest of the genus during the early-mid Pliocene The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58 ...

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.
