Перевод: oryx
[существительное] сернобык ; антилопа Бейза
Тезаурус:
- Many desert animals, from tortoises to addax and Arabian oryx, have abandoned the need to drink, except perhaps when pregnant.
- Arabian oryx also lick the dew that may accumulate on rocks and on each others' hair, as the humid air from the Arabian Sea rolls in at night.
- Prior to the Second World War this species was hunted, as part of a traditional subsistence economy, by Bedouin tribes but with the development of the oil industry and the introduction of modern vehicles and weapons, hunting parties organised on a large scale rapidly reduced oryx populations to such an extent that they were virtually eliminated.
- However, in relation to recreational hunting, a classic example of overexploitation is that of the Arabian oryx ( Oryx leucoryx ) in the Middle East.
- Domestic animals have over-grazed the area creating total desert conditions which are unsuitable for oryx.
- Scimitar-horned Oryx bred in British Zoos were reintroduced to Tunisia in 1987.
- In a study of 102 scimitar-horned oryx juvenile survival rates were shown to be inversely related to the degree of inbreeding.
- Some prey species such as the oryx (opposite, top), rely on simple, powerful galloping to escape their pursuers, but others, such as the impala (below), employ a more confusing, zigzag escape route, with sudden directional changes making it difficult for the pursuing attacker to strike.
- Moreover it is important to identify genetically suitable animals for reintroduction from zoos, where analysis can reveal which animals carry the under-represented founder oryx's genes and would therefore be good candidates.
- Scimitar-horned Oryx
- Oryx and ibex are scarce, but they are there.
- Oryx make better use of the available plant food than domestic animals, and if given adequate protection in the wild could become a valuable source of food for local people.
