Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sylvilagus Floridanus
The eastern cottontail (''Sylvilagus floridanus'') is a New World cottontail rabbit, a member of the family Leporidae. It is the most common rabbit species in North America.

It is also found on the Caribbean island of Margarita Island, Margarita. It is abundant in Midwest North America. Its range expanded north as forests were cleared by settlers.Godin, Alfred J. (1977). ''Wild mammals of New England''. Baltimore, MD: The Johns Hopkins University Press Originally, it was not found in New England, but it has been introduced and now competes for habitat there with the native New England cottontail. It has also been introduced into parts of Oregon, Washington (state), Washington, and British Columbia. In the 1950s and 1960s, the eastern cottontail was introduced to France and nort ...

Proechimys Semispinosus
Tome's spiny rat (''Proechimys semispinosus''), also known as Tomes' spiny rat or the Central American spiny rat, is a species of spiny rat distributed from Honduras to Ecuador. The IUCN has assessed its conservation status as being of "least concern". Description Tome's spiny rat is a large rat with a head-and-body length of between and a tail length of between . The head is long and slender, with prominent eyes and narrow erect ears. At night, the eyes reflect a reddish eyeshine. The feet are long with strong nails. The pelage is sleek with spines mixed in with the dorsal fur, though these are not very obvious in the field. The upper parts are reddish-brown while the underparts are white. The tail is almost hairless and is reddish-brown above and white below. About 20% of animals encountered have no tail. This rat could be confused with the armored rat (''Hoplomys gymnurus'') which is much the same size, but the armored rat has a longer snout and smaller eyes, which are less ...

Oryzomys Palustris
The marsh rice rat (''Oryzomys palustris'') is a semiaquatic North American rodent in the family Cricetidae. It usually occurs in wetland habitats, such as swamps and salt marshes. It is found mostly in the eastern and southern United States, from New Jersey and Kansas south to Florida and northeasternmost Tamaulipas, Mexico; its range previously extended further west and north, where it may have been a commensal in corn-cultivating communities. Weighing about , the marsh rice rat is a medium-sized rodent that resembles the common black and brown rat. The upperparts are generally gray-brown, but are reddish in many Florida populations. The feet show several specializations for life in the water. The skull is large and flattened, and is short at the front. John Bachman discovered the marsh rice rat in 1816, and it was formally described in 1837. Several subspecies have been described since the 1890s, mainly from Florida, but disagreement exists over their validity. The Florida Key ...

It is found from southern Mexico through Central America into South America, where it occurs south into Peru and Brazil, and includes numerous synonyms, including the type species of the genus, ''Oryzomys navus'' Bangs, 1899.

''Oecomys sydandersoni'' is an arboreal species of rodent in the genus ''Oecomys''. It lives in forest patches in a small area in eastern Bolivia. It is a medium-sized species, weighing about , with mostly grayish and brownish fur and short and broad hindfeet with well-developed pads. First collected in 1964, it was formally described in 2009.

Nectomys
''Nectomys'' is a genus of rodent in the tribe Oryzomyini of family Cricetidae. Musser and Carleton, 2005. It is closely related to ''Amphinectomys'' and was formerly considered congeneric with ''Sigmodontomys''. It consists of five species, which are allopatrically distributed across much of South America: ''Nectomys grandis'' in montane Colombia; ''Nectomys palmipes'' on Trinidad and in nearby Venezuela, ''Nectomys apicalis'' in the western margins of the Amazon biome, ''Nectomys rattus'' in much of Amazonia, and ''Nectomys squamipes'' in the Atlantic Forest of Brazil.
