Old World Rats And Mice
The Old World rats and mice, part of the subfamily Murinae in the Family (biology), 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 order (biology), orders except the bats and the remainder of the rodents. Description The Murinae are native to Africa, Europe, Asia, and Australia. They are terrestrial animal, terrestrial placental mammals. They have also been invasive species, introduced to all continents except Antarctica, and are serious pest animals. This is particularly true in island communities where they have contributed to the endangered, 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 (tooth), molar pattern th ...

Miocene
The Miocene ( ) is the first epoch (geology), 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 followed the Oligocene and preceded 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 distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...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 In ecology, a niche is the match of a species to a specific environmental condition. Three variants of ecological niche are described by It describes how an organism or population responds to the distribution of Resource (biology), resources an ... 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 plac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ''Coccymys'' is a genus of rodent in the family Muridae endemic to Indonesia and Papua New Guinea Papua New Guinea, officially the Independent State of Papua New Guinea, is an island country in Oceania that comprises the eastern half of the ... ...

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 (island), 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 pen ...

Chiromyscus
Fea's tree rat (''Chiromyscus chiropus'') or the Indochinese chiromyscus, is a species of rodent in the family Muridae. It is found in Yunnan (China), eastern Myanmar, northern Thailand, Laos, and Vietnam Vietnam, officially the Socialist Republic of Vietnam (SRV), is a country at the eastern edge of mainland Southeast Asia, with an area of about and a population of over 100 million, making it the world's List of countries and depende ....

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 finished coffee beans. The coffee cherry has the fruit or pulp removed leaving the seed or bean which is then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canariomys
''Canariomys'' is an extinct genus of rodents (Old World rats and mice) that once existed on the islands of Tenerife and Gran Canaria, part of the Canary Islands, Spain. These giant rats could reach a weight of about . They were herbivores; their diet was based on plant materials, probably soft vegetables such as roots, ferns, and berries, but not grass. ''C. tamarani'' were considered herbivores, eating everything plant-like except grass with good digging skills. While ''C. bravoi'' were considered as a rat character, because of its large size, with an omnivorous diet with good climbing skills. They were one of two groups of rodents native to the archipelago, alongside the lava mouse (''Malpaisomys insularis''), which was native to Fuerteventura and Lanzarote. Original distribution It is generally believed that the species of Tenerife lived in a wooded area linked to the laurisilva and that it had climbing abilities, whereas the species of Gran Canaria lived in more open e ...
