Oreoryzomys
''Oreoryzomys balneator'', also known as the Peruvian rice rat or Ecuadoran oryzomys, is a species of rodent in the tribe Oryzomyini of family Cricetidae. It is found in Ecuador and northern Peru in cloud forest at elevations from 1500 to 1800 m. It is the only species in the genus ''Oreoryzomys'', which was included in ''Oryzomys'' until 2006. The genus name ''Oreoryzomys'' is a combination of ορος the Greek word for "mountain" with the old genus name ''Oryzomys'' and refers to the mountainous habitat of ''O. balneator''. Recent research suggests that ''O. balneator'' is not closely related to ''Oryzomys'', but instead is probably related to ''Microryzomys'' within a clade also including ''Neacomys The genus ''Neacomys'', also known as bristly mice because of their spiny fur, includes several species of rodents in the tribe Oryzomyini of family Cricetidae. It is most closely related to ''Oligoryzomys'', ''Oreoryzomys'', and ''Microryzomys'' ...'' and '' Oligoryzomys''. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oryzomyini
Oryzomyini is a tribe of rodents in the subfamily Sigmodontinae of the family Cricetidae. It includes about 120 species in about thirty genera,Weksler et al., 2006, table 1 distributed from the eastern United States to the southernmost parts of South America, including many offshore islands. It is part of the clade Oryzomyalia, which includes most of the South American Sigmodontinae. The name ''Oryzomyini'' derives from that of its type genus, ''Oryzomys'', which means "rice rat" or "rice mouse". Many species are also known as rice rats. Taxonomy Contents of Oryzomyini An oryzomyine group was first envisaged by Oldfield Thomas in the early 20th century. He defined it to include pentalophodont species, which have a mesoloph(id) on the upper and lower molars, with a long palate (extending past the third molars). Thomas included ''Oligoryzomys'', ''Oecomys'', and ''Oryzomys'' (which included many species now in other genera), as well as '' Rhagomys'', which is currently classified ...

Oryzomys
''Oryzomys'' is a genus of semiaquatic rodents in the tribe Oryzomyini living in southern North America and far northern South America. It includes eight species, two of which—the marsh rice rat (''O. palustris'') of the United States and '' O. couesi'' of Mexico and Central America—are widespread; the six others have more restricted distributions. The species have had eventful taxonomic histories, and most species were at one time included in the marsh rice rat; additional species may be recognized in the future. The name ''Oryzomys'' was established in 1857 by Spencer Fullerton Baird for the marsh rice rat and was soon applied to over a hundred species of American rodents. Subsequently, the genus gradually became more narrowly defined until its current contents were established in 2006, when ten new genera were established for species previously placed in ''Oryzomys''. Species of ''Oryzomys'' are medium-sized rats with long, coarse fur. The upperparts are gray ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microryzomys
''Microryzomys'' is a genus of rodent in the tribe Oryzomyini of family Cricetidae. It is closely related to '' Oreoryzomys'', '' Oligoryzomys'', and ''Neacomys''.Weksler, 2006 It contains two species, both restricted to the Andes: '' M. altissimus'' and '' M. minutus''. Characteristics ''Microryzomys'' species are small members of the rodent tribe Oryzomyini, weighing in the region of , and characterised by their long soft fur and tail longer than their head-and-body-length. They have small hind feet with six fleshy pads on the under surface, and with the fifth toe nearly as long as the middle three. The four pairs of mammae are arranged in the typical fashion for members of the tribe. At one time, this genus was considered to be a subgenus of ''Oryzomys'', but Carleton and Musser (1989) raised it to full generic status on the basis of various anatomic details of skull and dentition and on certain morphological traits. Distribution ''Microryzomys'' is found in high mountainous a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the 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, 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 Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history.

Oligoryzomys
''Oligoryzomys'' is a genus of rodents in the tribe Oryzomyini of family Cricetidae. Many species are known as pygmy rice rats or colilargos.Musser and Carleton, 2005 The genus is found from Mexico to Tierra del Fuego and includes approximately 17 species. In Argentina and Chile, ''Oligoryzomys longicaudatus'' and other members of the genus represent the reservoir for the hantavirus strain Andes virus (ANDV) (Wells et al., 1997; Levis et al., 1998; Cantoni et al., 2001). Taxonomy The genus ''Oligoryzomys'' is included in the subfamily Sigmodontinae of the family Cricetidae. The genus is placed in the Oryzomyini tribe, first proposed by Oldfield Thomas in the early 20th century. It includes genera that have certain dental features of the upper and lower molars and a long palate which extends past the third molars. More recently, molecular analysis and morphological data has placed the genus in Clade C, alongside ''Neacomys'', ''Microryzomys'' and ''Oreoryzomys''. Characteristics ...

Neacomys
The genus ''Neacomys'', also known as bristly mice because of their spiny fur, includes several species of rodents in the tribe Oryzomyini of family Cricetidae. It is most closely related to ''Oligoryzomys'', ''Oreoryzomys'', and ''Microryzomys''. ''Neacomys'' species are mainly found in the Amazon basin, but '' N. pictus'' occurs in Panama and '' N. tenuipes'' in montane Colombia.Musser and Carleton, 2005 Species There are currently about 19 described species in the genus. *'' Neacomys aletheia'' — upper Juruá bristly mouse *'' Neacomys amoenus'' — pleasant bristly mouse *''Neacomys dubosti'' — Dubost's bristly mouse *'' Neacomys guianae'' — Guiana bristly mouse *'' Neacomys elieceri'' — Eliecer's bristly mouse *'' Neacomys jau'' — Jaú bristly mouse *'' Neacomys macedoruizi'' — Macedo Ruiz's bristly mouse *'' Neacomys marajoara'' — Marajó bristly mouse *''Neacomys minutus'' — small bristly mouse *''Neacomys musseri'' — Musser's bristly mouse *''Neacom ...

Taxa Named By Oldfield Thomas
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Peru
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saurop ...
