Lindbergh's Oryzomys
''Cerradomys scotti'', also known as Lindbergh's oryzomys, is a rodent species from South America in the genus '' Cerradomys''. It is terrestrial and is found in the cerrado (savanna) ecozone of south central Brazil, Bolivia and Paraguay. The species is common and appears to tolerate a degree of agricultural habitat modification. It was first described in 2002 as ''Oryzomys scotti'', after zoologist Scott Lindbergh. In 2004, another new species, ''Oryzomys andersoni'', was described by a team from Texas Tech University on the basis of a specimen taken at Pozo Mario, Santa Cruz Department, southeastern Bolivia. It was named after eminent mammalogist Sydney Anderson in honor of his contributions to the study of Bolivian mammals.Brooks et al., 2004, p. 3 It was subsequently recognized as belonging to the same species as ''Oryzomys scotti'' on the basis of morphological and molecular evidence. In 2006, the species was transferred to the new genus ''Cerradomys'', so that it became kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

American Museum Of Natural History
The American Museum of Natural History (AMNH) is a natural history museum on the Upper West Side of Manhattan in New York City. Located in Theodore Roosevelt Park, across the street from Central Park, the museum complex comprises 21 interconnected buildings housing 45 permanent exhibition halls, in addition to a planetarium and a library. The museum collections contain about 32 million specimens of plants, animals, fungi, fossils, minerals, rocks, meteorites, human remains, and human cultural artifacts, as well as specialized collections for frozen tissue and genomic and astrophysical data, of which only a small fraction can be displayed at any given time.

Mazama Gouazoupira
The gray brocket (''Mazama gouazoubira''), also known as the brown brocket, is a species of brocket deer from northern Argentina, Bolivia, southern Peru, eastern and southern Brazil, Paraguay, and Uruguay. It formerly included the Amazonian brown brocket (''M. nemorivaga'') and sometimes also the Yucatan brown brocket (''Odocoileus pandora'') as subspecies.Medellín, R. A., A. L. Gardner, J. M. Aranda (1998). ''The taxonomic status of the Yucatán brown brocket, Mazama pandora (Mammalia: Cervidae).'' Proceedings of the Biological Society of Washington 111 (1): 1–14. Unlike other species of brocket deer in its range, the gray brocket has a gray-brown fur without reddish tones.Wilson, D. E., Mittermeier, R. A., editors (2011). ''Handbook of the Mammals of the World, vol. 2 (Hoofed Mammals), p. 441. Name The scientific name of the gray brocket deer comes from Félix de Azara's ''gouazoubira''.

Red Brocket
The red brocket (''Mazama americana'') is a species of brocket deer from forests in South America, ranging from northern Argentina to Colombia and the Guianas. It also occurs on the Caribbean island of Trinidad (it also occurred on the island of Tobago until very recent historical times, but has been extirpated there). Taxonomy It formerly included the Central American red brocket (''M. temama'') and sometimes the Yucatan brown brocket (''M. pandora'') as subspecies. Considerable taxonomic confusion still exists for the populations remaining in the red brocket. Pending a solution to this, it has been evaluated as data deficient by the IUCN, though as presently defined, it is the most widespread species of brocket. It is sympatric with the smaller Amazonian brown brocket over much of its range (the latter tends to have significantly lower population densities).

Crab-eating Fox
The crab-eating fox (''Cerdocyon thous''), also known as the forest dog, wood fox, bushfox (not to be confused with the bush dog) or maikong, is an extant species of medium-sized canid endemic to the central part of South America since at least the Pleistocene epoch. Like South American foxes, which are in the genus ''Lycalopex'', it is not closely related to true foxes. ''Cerdocyon'' comes from the Greek words ''kerdo'' (meaning fox) and ''kyon'' (dog) referring to the dog- and fox-like characteristics of this animal. Taxonomy and evolution The crab-eating fox was originally described as ''Canis thous'' by Linnaeus (1766), and first placed in its current genus ''Cerdocyon'' by Hamilton-Smith in 1839. Cerdocyonina is a tribe which appeared around 6.0 million years ago (Mya) in North America as '' Ferrucyon avius'' becoming extinct by around 1.4–1.3 Mya. living about . This genus has persisted in South America from an undetermined time, possibly around 3.1 Mya, and continue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nine-banded Armadillo

Dasyprocta Punctata
The Central American agouti (''Dasyprocta punctata'') is a species of agouti from the family Dasyproctidae. The main portion of its range is from Chiapas and the Yucatan Peninsula (southern Mexico), through Central America, to northwestern Ecuador, Colombia and far western Venezuela. A highly disjunct population is found in southeastern Peru, far southwestern Brazil, Bolivia, western Paraguay and far northwestern Argentina. The disjunct population has been treated as a separate species, the brown agouti (''Dasyprocta variegata''),Emmons, L. H. (1997). ''Neotropical Rainforest Mammals.'' Pp. 227–229. 2nd edition. but a major review of the geographic variation is necessary. The Central American agouti has also been introduced to Cuba and the Cayman Islands. Though some populations are reduced due to hunting and deforestation, large populations remain and it is not considered threatened.

''G. spixii'' tolerates a wide range of environmental changes, though they need open habitats. It is the most stable species within the ''Galea'' group because it is extremely abundant throughout its range. Gestation is about fifty days.
