Species

Hippocamelus is a genus of Cervidae, the deer family. It comprises two extant Andean and two fossil species. The living members are commonly known as the huemul (from the Mapuche language), and the taruca, also known as northern huemul.

Contents

Both species have a stocky, thick, and short-legged body. They live at high altitudes in the summer. Though Taruca spends their whole life cycle at these high altitudes, especially as populations get nearer the Ecuator line, Southern Huemul, moves down the mountains in the fall and spend the winter in sheltered forested valleys.

Areas with fresh water are preferred. They are herbivores that feed primarily on herbaceous plants and shrubs as well as sedges, lichens, and grasses found between the rocks on high peaks. They are active during daytime and have a lifespan of about ten years.[ citation needed ]

Extant species

Huemul

The huemul (Hippocamelus bisulcus), also known as the South Andean deer, is found in Chile and Argentina. Huemuls live in groups of varying size, typically of two or three individuals, but sometimes as many as eleven. In the past, groups of over a hundred deer were reported.[ citation needed ] Groups are made up of a female and her young, while males are often alone.

Huemul occur in several national parks in Chile and neighbouring parts of Argentina and have been on the Endangered list since 1996. They are endangered primarily due to human impacts such as deforestation, habitat fragmentation by roads, introduction of non-native mammals such as farm animals, and poaching. They are in a classic "extinction spiral" marked by increasingly small, isolated populations.[ citation needed ]

The huemul is, along with the condor, the national animal of Chile.

Taruca

The taruca (Hippocamelus antisensis), also called Northern Huemul, is mainly found in Peru. Scattered potpulations are also found in high mountain regions of Bolivia, and in a less extent in northern Chile and Argentina, inhabiting treeless Puna grasslands. They live at high altitudes ranging from 3,500 to 5,200 meters above sea level.

Social habits include grazing in flexible groups of up to thirty animals consisting of one or two males and several females. [1]

Taxonomy and evolution

In 2008, a genetic study indicated that the huemul and taruca may not be closely related, and that the taruca should therefore be placed in a separate genus. [2] This has been contradicted by more recent studies. [3]

Fossils belonging to the now extinct species Hippocamelus sulcatus have been identified from Brazil, Uruguay, and Argentina. This species inhabited lowland plains habitats, rather than mountains, and lived between 1.5 and 0.5 million years ago, during the mid to late Pleistocene. Its exact relationship to the living species is unclear. A second fossil species, Hippocamelus percultus , is known from the Bolivian Andes, and lived around 40,000 to 20,000 years ago; it may be a direct ancestor of the living taruca. [4]

Conservation

Both species are threatened according to the IUCN. The Southern Hueamul is endangered and the taruca is listed as vulnerable.

The Andes, Andes Mountains or Andean Mountain Range are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 8,900 km (5,530 mi) long, 200 to 700 km wide, and has an average height of about 4,000 m (13,123 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.

<span class="mw-page-title-main">Deer</span> Family of mammals

A deer or true deer is a hoofed ruminant mammal of the family Cervidae. The two main groups of deer are the Cervinae, including muntjac, elk (wapiti), red deer, and fallow deer; and the Capreolinae, including reindeer (caribou), white-tailed deer, roe deer, and moose. Male deer of all species, as well as female reindeer, grow and shed new antlers each year. In this, they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla).

<i>Pudu</i> Genus of mammals belonging to the deer, muntjac, roe deer, reindeer, and moose family of ruminants

The pudus are two species of South American deer from the genus Pudu, and are the world's smallest deer. The chevrotains are smaller, but they are not true deer. The name is a loanword from Mapudungun, the language of the indigenous Mapuche people of central Chile and south-western Argentina. The two species of pudus are the northern pudu from Venezuela, Colombia, Ecuador, and Peru, and the southern pudu from southern Chile and south-western Argentina. Pudus range in size from 32 to 44 centimeters tall, and up to 85 centimeters (33 in) long. The southern pudu is classified as near threatened, while the northern pudu is classified as Data Deficient in the IUCN Red List.

The Capreolinae, Odocoileinae, or the New World deer are a subfamily of deer.

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.
