Acute phase protein response in the capybara (Hydrochoerus hydrochaeris).
Management implications of capybara social behavior. Capybaras are strong swimmers, helped by the fact that their bodies are only slightly denser than water.
Narrative of the surveying voyages of His Majesty’s Ships Adventure and Beagle between the years anddescribing their examination of the southern shores of South America, and the Beagle’s circumnavigation of the globe. A hydrocuaeris form of scent secretion is coated on these hairs and is released when in contact with objects such as plants. This species is distinguished from the lesser capybara, Hydrochoerus isthmiusby its larger size 5although there is some confusion over the distributional boundaries of these species 1.
This article is about the animal. Capybaras are semiaquatic mammals  found throughout almost all countries of South America except Chile.
Journal of Animal Ecology Chapman and Hall, London. The capybara Hydrochoerus hydrochaeris is a mammal native to South America.
They can be found in many areas in zoos and parks and may live for 12 years in captivity. Revista Brasileira de Zoologia. Capybaras are known to be gregarious. Group living appears to be extremely important to capybara survival—without a group, an individual is excluded from most grazing habitat and has no chance of finding a mate, so solitary capybaras are seldom found.
Animals portal Latin America portal. Retrieved 8 June Hydrochoerus hydrochaeris English names: Despite these threats, the species still has a wide distribution and large global population 1and the increasing conversion of forest to grassland, together hyydrochoerus management regimes employed on cattle ranches such as predator control, provision of water, and burningmay even be helping to create more suitable capybara habitat 5 9.
Capybaras sometimes raid gardens or farms in search of food, such as melons, squashes, or grains. Mammalian Species Their hide was once traded in Argentina which caused the death of more than 80, of them.
Biological Conservation Hydrochoerux, in addition to the location of the eyes, ears, and nostrils on top of the head, make capybaras well-suited to semi-aquatic life. Rock Cavy Kerodon rupestris Acrobatic cavy Kerodon acrobata.
Both males and females have two glands on either side of the anus. Accessed April 09, at http: The capybara is also sometimes killed by farmers as a pest, either because it may attack cereal or fruit crops, or because it is mistakenly viewed as a competitor with domestic livestock 3 4 6 9.

Male capybaras have a bare lump on the top of the snout, known as the morillo gland, which secretes a white liquid.
Glossary Gestation The state of being pregnant; the period from conception to birth. We examined the histology of testes of capybaras Hydrochoerus hydrochaeris hydrocherus the relationship among mass of testes, body mass, and the ratio of seminiferous tubules to interstitial tissue. In fact, capybaras are more efficient grazers than cattle or other introduced livestock and are already an important source of food for many local people. However, when the wet season returns, these aggregations split into the original groups that formed them 3 5 8.
