Rangifer Tarandus
Reindeer (in North American English, known as caribou if wild and ''reindeer'' if domesticated) are deer in the genus ''Rangifer''. For the last few decades, reindeer were assigned to one species, ''Rangifer tarandus'', with about 10 subspecies. A 2022 revision of the genus elevated five of the subspecies to species (see Taxonomy below). They have a circumpolar distribution and are native to the Arctic, sub-Arctic, tundra, boreal forest, and mountainous regions of northern Europe, Siberia, and North America. Reindeer occur in both migratory and sedentary populations, and their herd sizes vary greatly in different regions. The tundra subspecies are adapted for extreme cold, and some are adapted for long-distance migration. Reindeer vary greatly in size and color from the smallest species, the Svalbard reindeer (''R. t. platyrhynchus''), to the largest subspecies, Osborn's caribou (''R. t. osborni''). Although reindeer are quite numerous, some species and subspecies are in d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mazama (genus)
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 only distantly related. About 10 species of brocket deer are described. The genus name ''Mazama'' is derived from Nahuatl ''mazame'', the plural of ''mazatl'' "deer". The common English name "brocket" (from French ''brocart'' < ''broche'', spindle) comes from the word for a stag in its second year, with unbranched antlers. Taxonomy The among ''Mazama'' species has changed significantly in the last decades, and as recently as 1999, some authorities only recognized four species.Now ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mazama Americana
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).

Mazama Gouazoubira
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 (''M. 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''.

Hippocamelus Bisulcus
The south Andean deer (''Hippocamelus bisulcus''), also known as the southern guemal, south Andean huemul, southern huemul, or Chilean ''huemul'' or '' güemul'' ( , ), is an endangered species of deer native to the mountains of Argentina and Chile. Along with the northern guemal or taruca, it is one of the two mid-sized deer in the ''Hippocamelus'' genus and ranges across the high mountainsides and cold valleys of the Andes. The distribution and 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 ..., behaviour, and diet of the deer have all been the subject of study. The viability of the small remaining population is an outstanding concern to researchers. The huemul is part of Coat of arms of Chile, Chile's national coat of arms and is since 2006 a National Natural Monument. ...

Blastocerus Dichotomus
The marsh deer (''Blastocerus dichotomus'') is the largest deer species from South America reaching a length of and a shoulder height of . It is found in Argentina, Bolivia, Peru, Brazil, Uruguay and Paraguay. Formerly found in much of tropical and subtropical South America, it ranged east of the Andes, south from the Amazon rainforest, west of the Brazilian Atlantic rainforest and north of the Argentinian Pampa. Today it is largely reduced to isolated populations at marsh and lagoon zones in the Paraná, Paraguay, Araguaia and Guapore river basins.
