Mountain coatis are two species of procyonid mammals from the genus Nasuella. Unlike the larger coatis from the genus Nasua, mountain coatis only weigh 1.0–1.5 kilograms (2.2–3.3 lb) and are endemic to the north Andean highlands in South America.
The pygmy brocket is a brocket deer species from South America. It is found in southern Brazil, Argentina and Paraguay. It is a small deer with short legs, weighing 15 to 20 kilograms. It is reddish-brown in color.
Brockets or brocket deer are the species of deer in the genus Mazama. They are medium to small in size, and are found in the Yucatán Peninsula, Central and South America, and the island of Trinidad. Most species are primarily found in forests. They are superficially similar to the African duikers and the Asian muntjacs, but unrelated. About 10 species of brocket deer are described.
The red brocket 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.
The gray brocket, 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 and sometimes also the Yucatan brown brocket as subspecies. Unlike other species of brocket deer in its range, the gray brocket has a gray-brown fur without reddish tones.
The rufous mouse opossum or little rufous mouse opossum is an opossum species from South America. The species has been found in Bolivia, Surinam, French Guinea, Brazil, Colombia, Ecuador, Guyana, Peru and Surinam in lowland tropical rainforest at altitudes from 100 to 1000 m. It is presumed to feed on insects and fruit, like its close relatives.
The dwarf fat-tailed mouse opossum, also known as the velvety fat-tailed opossum is an opossum species from South America. It is endemic to Brazil, where it is found in cerrado and caatinga habitats. Its head-and-body length is about 141-212 mm, and its tail length is about 73-85 mm. Its diet is 44% arthropods; 75% of its diet consists of animals and animal products. Its ventral fur is entirely gray-based. Its hind foot is less than 14 mm, which is short for the genus.
The dwarf brocket, or chunyi, is a small species of deer native to the Andean highlands in western Bolivia and southeastern Peru, where it is found in forest and páramo. Its pelage is reddish-brown with dark grey foreparts and neck. The underparts are lighter brown, and the muzzle short and thick. It weighs around 11 kg.
The Yucatan brown brocket is a small species of deer native to the Yucatán Peninsula of Mexico, Belize and Guatemala. While it is found in humid tropical forest like most other brocket deer, the Yucatan brown brocket also ranges across arid, relatively open habitats.
Microryzomys minutus, also known as the montane colilargo or the forest small rice rat, is a species of rodent in the genus Microryzomys of family Cricetidae. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela, but these populations may represent more than one species.
The common fat-tailed mouse opossum is a species of opossum in the family Didelphidae. It occurs in Argentina, Bolivia, Brazil, and Paraguay in chaco and Andean foothill habitats. Its head-and-body length is about 75 to 120 mm, and its tail length is about 90 to 134 mm. Its dorsal fur is brownish gray, and its ventral fur is yellowish to white. The legs and cheeks are the same color as the ventral surface. Its tail is sharply bicolored. A ring of faintly darker fur surrounds each eye. Its tail often lacks fat deposits, but does not always.
The small red brocket is a small species of deer in the family Cervidae. It is endemic to Atlantic Forest in Paraná, Santa Catarina and São Paulo in southeastern Brazil. This species, which only was scientifically described in 1996, is threatened by habitat loss. Though its size and structure most resemble that of the pygmy brocket, its coloration is very similar to that of the red brocket. It resembles hybrids between these two species even more closely, but differs from both, and their hybrids, in karyotype.
The Mérida brocket, also known as the Meroia brocket or rufous brocket, is a small species of deer. It is found in forest and páramo at altitudes of 1,000–3,500 metres (3,300–11,500 ft) in the Andes of northern Colombia and western Venezuela. It was once treated as a subspecies of the similar little red brocket, but has been considered a distinct species since 1987, though as recent as 1999 some maintained it as a subspecies.
The Capreolinae, Odocoileinae, or the New World deer are a subfamily of deer. Alternatively, they are known as the telemetacarpal deer, due to their bone structure being different from the plesiometacarpal deer subfamily Cervinae. The telemetacarpal deer maintain their distal lateral metacarpals, while the plesiometacarpal deer maintain only their proximal lateral metacarpals. The Capreolinae are believed to have originated in the Middle Miocene, between 7.7 and 11.5 million years ago, in Central Asia.
The little black serotine is a species of insectivorous vesper bat. It is found in Colombia, Ecuador, Peru, Venezuela, Bolivia and Brazil at elevations from 100 to 3300 m.
The Central American red brocket is a species of brocket deer ranging from southern Mexico, through Central America, to northwestern Colombia. In 1792 Robert Kerr originally described it as a unique separate species as opposed to a subspecies. It was treated as a subspecies of the red brocket from South America, but its karyotype has 2n = 50, while the latter's was initially described as having 2n = 68–70. However, a more recent description gives the red brocket a variable karyotype with 2n ranging from 48 to 54, suggesting it represents several species. It is sympatric with the Yucatan brown brocket over part of its range. Additionally, it was estimated that Mazama temama diverged from other red brocket deer about 2 MYA. This was estimated through analysis of concatenated sequences from the mitochondrial gene ND2, Cytb, and tRNA-Pro-Control region. The species is found in primary and secondary tropical forest at altitudes from sea level to 2800 m. In Mexico, it is regarded as an agricultural pest by bean farmers. It is probably threatened by hunting and deforestation.
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.
The Amazonian brown brocket, also known as the small brown brocket, is a small species of deer that is almost entirely restricted to South America.
