Murine
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents. Description The Murinae are native to Africa, Europe, Asia, and Australia. They are terrestrial placental mammals. They have also been introduced to all continents except Antarctica, and are serious pest animals. This is particularly true in island communities where they have contributed to the endangerment and extinction of many native animals. Two prominent murine species have become vital laboratory animals: the brown rat and house mouse are both used as medical subjects. The murines have a distinctive molar pattern that involves three rows of cusps instead of two, the primitive pattern seen most frequently in mur ...

Baiyankamys
'' Baiyankamys'' is a genus of amphibious murid rodents. It was originally described, along with the species ''Baiyankamys shawmayeri'' by Hinton in 1943 after he found the remains of a single individual in south east of the Bismarck Mountain Range, north east New Guinea. Tate, in 1951 and, Laurie and Hill in 1954, confirmed the existence of both the species and genus. Classification Hinton described '' Baiyankamys'' as similar in appearance to the species ''Hydromys habbema'' but differed due to its unreduced pinnae and its lower teeth. It was described as having three lower molars on both sides of the lower jaw, whereas other genera of amphibious murines in New Guinea have only two. In 1968 Mahoney discovered that the specimen of ''B. shawmayeri'' was a composite resulting from an incorrectly associated mandible of the species '' Rattus niobe'' and the skull of a small water rat. When the correct mandible was found in the BMNH collections Mahoney proposed that, based on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrotomys
The genus ''Chrotomys'' contain a unique group of rodents found only in the Philippines, specifically the islands of Luzon, Mindoro, and Sibuyan. Instead of being predominantly herbivorous or omnivorous like other murines, these rats feed predominantly on invertebrates although they do eat some vegetable matter. This vermivory is probably the result of a rat-like animal moving into an ecological niche usually filled by shrews. Shrews and other insectivores are absent on these Philippine islands. Taxonomy Rickart et al. (2005) found that ''C. mindorensis'', ''C. whiteheadi'', and ''C. gonzalesi'' are closely related whereas ''C. silaceus'' and ''C. sibuyanensis'' represent earlier offshoots of the genus. Several authors place ''C. silaceus'' in the genus ''Celaenomys'', but Rickart et al. (2005) suggest that neither genetic nor morphometric distance warrant it. These rats are considered "old endemics" and are probably the result of one of the first colonisations of the Phil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ar ...

Chiruromys
''Chiruromys'' is a genus of Old World mouse that is restricted to New Guinea and the nearby islands of Goodenough, Fergusson, and Normanby. Characteristics These are small arboreal rats with long tails. Head and body is , tail is , and weight is .Nowak, 1999 The fur is grey to brown above with a white belly. They are restricted to forests where they spend all of their time in the canopy. They live in groups usually consisting of a breeding pair and their offspring (usually one to three) (Nowak, 1999). Classification Musser and Carleton (2005) considered ''Chiruromys'' to be a member of the ''Pogonomys'' Division within the Murinae along with the genera ''Pogonomys'', '' Hyomys'', ''Macruromys'', ''Mallomys'', ''Coccymys'', and '' Anisomys''. It is considered a New Guinea Old Endemic, part of the initial wave of murines colonizing the island.

Chiropodomys
''Chiropodomys'' (or pencil-tailed tree mice) is a genus of Old World rats and mice native to Southeast Asia and northeast India. They are tree-dwelling, very small mice, mostly found in tropical rainforest. In total six extant species have been identified, but only one of these, ''Chiropodomys gliroides'', is common and widely distributed, and has been extensively studied. Species Genus ''Chiropodomys'' — pencil-tailed tree mice: *Palawan pencil-tailed tree mouse, ''Chiropodomys calamianensis'' Taylor, 1934, Palawan and neighboring islands *Indomalayan pencil-tailed tree mouse, ''Chiropodomys gliroides'' Blyth, 1856, northeast India, southeastern China, mainland Southeast Asia, Sumatra, Java *Koopman's pencil-tailed tree mouse, ''Chiropodomys karlkoopmani'' Musser, 1979, Mentawai Islands * Large pencil-tailed tree mouse, ''Chiropodomys major'' Thomas, 1893, Borneo *Gray-bellied pencil-tailed tree mouse, ''Chiropodomys muroides'' Medway, 1965, Borneo *Small pencil-tailed tree m ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Chingawaemys
The Chingawa forest rat (''Chingawaemys rarus'') is a species of rodent endemic to Ethiopia. It is the only member of the monotypic genus ''Chingawaemys''. It was only described in 2021, when it was discovered during a broad phylogenetic analysis of the tribe Praomyini. It is thought to have diverged from its closest relatives over 6 million years ago, during the Pliocene. The species inhabits the last remnant of tropical rainforest present in Ethiopia, in an area called Chingawa near the border with South Sudan. It is only known from one specimen collected 15 years prior to description, and researchers have been unable to regain access the type locality of the specimen. The genus is at major risk of extinction due to mass deforestation in the area for coffee production Coffee production is the industrial process of converting the raw fruit of the coffee plant into the finished coffee. The coffee cherry has the fruit or pulp removed leaving the seed or bean which is then dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
