Euryoryzomys
''Euryoryzomys'' is a genus of rodents in the tribe Oryzomyini of family Cricetidae. It includes six species, which are distributed in South America. Until 2006, its members were included in the genus ''Oryzomys'', but they are not closely related to the type species of that genus, and therefore they were placed in a new genus. They are most closely related to genera like ''Hylaeamys'' and ''Transandinomys''; many members of these genera were previously placed in a single species, known as ''Oryzomys capito''. The genus name, ''Euryoryzomys'', combines the name "''Oryzomys''" with the Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC.

Euryoryzomys Emmonsae
''Euryoryzomys emmonsae'', also known as Emmons' rice rat or Emmons' oryzomys, is a rodent from the Amazon rainforest of Brazil in the genus ''Euryoryzomys'' of the family Cricetidae. Initially misidentified as '' E. macconnelli'' or '' E. nitidus'', it was formally described in 1998. A rainforest species, it may be scansorial, climbing but also spending time on the ground. It lives only in a limited area south of the Amazon River in the state of Pará, a distribution that is apparently unique among the muroid rodents of the region. ''Euryoryzomys emmonsae'' is a relatively large rice rat, weighing , with a distinctly long tail and relatively long, tawny brown fur. The skull is slender and the incisive foramina (openings in the bone of the palate) are broad. The animal has 80 chromosomes and its karyotype is similar to that of other ''Euryoryzomys''. Its conservation status is assessed as "Data Deficient", but deforestation may pose a threat to this species. Taxonomy In ...

Euryoryzomys Russatus
''Euryoryzomys russatus'', also known as the russet oryzomys, russet rice rat, or big-headed rice rat, is a species of rodent in the family Cricetidae. It is a member of the genus ''Euryoryzomys'', which was split off from ''Oryzomys'' in 2006. It was first described by Johann Andreas Wagner in 1848. It is found in southern Brazil, eastern Paraguay and northeastern Argentina. It is considered a large species in its genus, with a reddish-brown coat, long tail length, and large skull. It is a terrestrial rodent, spending its time foraging for seeds, fruits, and insects. It is listed by the IUCN as least concern, although studies have shown it to be influenced by anthropogenic disturbances. Predators consist of small members of the order Carnivora. Etymology The prefix eury- comes from the Greek word 'eurys'' meaning "wide" or "broad". The specific epithet ''russatus'' comes from the Latin word 'russatus', meaning "clothed in red".

Euryoryzomys Nitidus
''Euryoryzomys nitidus'', also known as the elegant oryzomys or elegant rice rat, is a rodent species in the family Cricetidae. Previously it was known as ''Oryzomys nitidus'', but it is not closely related to ''Oryzomys'' as that genus is now constructed. Its range includes Bolivia, Brazil and Peru to the east of the Andes, in lowland tropical rainforest as well as forest in the eastern foothills of the mountains, at elevations from . Description ''Euryoryzomys nitidus'' is a medium-sized rice rat with a head-and-body length of about and a similar length tail. The short dense fur on the head and back is tawny or tawny-brown, the sides of the head and flanks being tinged with ochre. The underparts are whitish-grey. The tail is a uniform colour apart from the underside near the tip which is mottled. The upper surfaces of both fore- and hind-feet are clad in white hair, and the nails are hidden by tufts of hair growing between them. Distribution and habitat The main population of ...

Transandinomys
''Transandinomys'' is a genus of rodents in the tribe Oryzomyini of family Cricetidae. It includes two species—'' T. bolivaris'' and '' T. talamancae''—found in forests from Honduras in Central America south and east to southwestern Ecuador and northwestern Venezuela in northern South America. Until 2006, its members were included in the genus ''Oryzomys'', but phylogenetic analysis showed that they are not closely related to the type species of that genus, and they have therefore been placed in a new genus. They may be most closely related to genera like ''Hylaeamys'' and '' Euryoryzomys'', which contain very similar species. Both species of ''Transandinomys'' have had eventful taxonomic histories. ''Transandinomys bolivaris'' and ''T. talamancae'' are medium-sized, soft-furred rice rats. The upperparts—brownish in ''T. bolivaris'' and reddish in ''T. talamancae''—are much darker than the whitish underparts. Both species are characterized by ver ...

Euryoryzomys Lamia
''Euryoryzomys lamia'', also known as the buffy-sided oryzomysMusser and Carleton, 2005 or monster rice rat, is a species of rodent in the family Cricetidae. It is found only in central Brazil, where it lives in forest enclaves within the cerrado. The species' known altitudinal range is from 700 to 900 m. The main threats to its survival are the destruction and fragmentation of its forest habitat In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical ....

Hylaeamys
''Hylaeamys'' is a genus of South American oryzomyine rodents found principally in humid forested areas east of the Andes. The species in this genus have historically been placed in ''Oryzomys''. They are most closely related to ''Euryoryzomys'', ''Transandinomys'', '' Nephelomys'', '' Oecomys'', and ''Handleyomys'', and most closely resemble species of the former two genera. They are distinguished from members of ''Euryoryzomys'' by all-dark or indistinct two-tone tail coloration (as opposed to the distinct two-tone tail coloration of ''Euryoryzomys''), from members of ''Transandinomys'' by having shorter whiskers above their eyes that do not extend posteriorly behind their ears, and in both cases by differences in carotid circulation. The genus is named after ''hylaea'' ("forest" in Greek), the term used by Humboldt for the lowland South American rainforests that are the main habitat of the genus. The genus currently comprises the following species: * '' Hylaeamys acritus'' * ' ... [...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] |
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.
