Marmosa Perplexa
The 27 species in the genus ''Marmosa'' are relatively small Neotropical realm, Neotropical members of the family (biology), family Didelphidae. This genus is one of three that are known as mouse opossums. The others are ''Thylamys'' (the "fat-tailed mouse opossums") and ''Tlacuatzin'', the grayish mouse opossum. Members of the genus ''Marmosops'' used to be called "slender mouse opossums", but are now just called "slender opossums". The thirteen members of the ''Marmosa'' subgenus ''Micoureus'', known as woolly mouse opossums, were formerly considered to be a separate genus, but were moved into ''Marmosa'' in 2009. Based on a comparison of sequences of one mitochondrial and three nuclear genes, three new subgenera, ''Eomarmosa'', ''Exulomarmosa'' and ''Stegomarmosa'', were recognized by Voss ''et al.'' in 2014. ''Eomarmosa'' and ''Exulomarmosa'', as well as ''Marmosa'' and ''Micoureus'', are thought to be sister taxa, while ''Stegomarmosa'' is viewed as sister to ''Marmosa'' plus ...

John Edward Gray
John Edward Gray (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marmosa Isthmica
The Isthmian mouse opossum (''Marmosa isthmica'') is a species of opossum in the family Didelphidae found in Colombia, Ecuador, and Panama.Fiona A. Reid, ''A field guide to the mammals of Central America & Southeast Mexico'' (OUP USA, 2009)p. 50/ref> Foraging along branches and vines for fruit and insects, with the help of a prehensile tail, ''M. isthmica'' was formerly considered a subspecies of Robinson's mouse opossum (''Marmosa robinsoni'') and is supposed to be similar to it in habit, but following Rossi (2005) it is now deemed a species. In 1935 in the Panama Canal Zone, Enders observed ''Marmosa isthmica'' to build nests with leaves in a nestbox fixed to a tree.Papéis Avulsos de Zoologia: vol. 41 (1999), Issues 1-14, p. 177 Notes References *Gardner, A.

Robert S
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' () "fame, glory, honour, praise, renown, godlike" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin.Reaney & Wilson, 1997. ''Dictionary of English Surnames''. Oxford University Press. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe, the name entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including En ...

Marmosa Paraguayanus
Tate's woolly mouse opossum (''Marmosa paraguayana'') is an omnivorous, arboreal South American marsupial of the family Didelphidae, named by American zoologist George Henry Hamilton Tate. It is native to Atlantic coastal forests of Brazil, Paraguay and Argentina. The species lives in both primary and secondary forest, including forest fragments within grassland. Insects are a major component of its diet. It was formerly assigned to the genus '' Micoureus'', which was made a subgenus of ''Marmosa'' in 2009.

Marmosa Tyleriana
Tyler's mouse opossum (''Marmosa tyleriana'') is a South American marsupial of the family Didelphidae. It lives in rainforests of the Guiana Highlands of southern Venezuela at elevations between 1300 and 2200 m. The species has only been found on three isolated tepuis ( Auyantepui, Marahuaca and Sarisariñama). All three of these locations are in protected areas ( Canaima, Duida-Marahuaca and Jaua-Sarisariñama national parks). The Latin species name refers to the habitat in which the opossum was first found, a '' Tyleria'' forest. In turn, both the genus ''Tyleria'' and the opossum's common name refer to Sidney F. Tyler, an American historian and photographer who helped finance the 1928-29 expedition of the American Museum of Natural History to the headwaters of the Orinoco The Orinoco () is one of the longest rivers in South America at .

Marmosa Andersoni
The heavy-browed mouse opossum (''Marmosa andersoni''), or Anderson's mouse opossum, is a species of opossum in the family Didelphidae. It is endemic to a restricted range in southern Peru.

In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally (scansorial), but others are exclusively arboreal. The hab ....

Marmosa Lepida
The rufous mouse opossum (''Marmosa lepida'') or little rufous mouse opossum is an opossum species from South America. The species has been found in Bolivia, French Guinea, Brazil, Colombia, Ecuador, Guyana, Peru and Suriname in lowland tropical rainforest at altitudes from . It is presumed to feed on insects and fruit, like its close relatives. It is considered a monotype. It is smaller in size and has a brighter red colored fur, distinguishing it from other congeners. Though the species has been known for over a century, very few specimens have been studied, most of these from areas below and taken from western edges of the Amazon basin and Guianas. Its dorsal pelage is reddish-brown and its ventral pelage is grayish. Researchers believe this coloring is product of adaptation to a humid forest A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating facto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
