Abstract: Gazella subgutturosa is an important ungulate species in desert and semidesert areas of Eurasian Continent, and ranked in grade Ⅱ key protected wildlife in China, and in Vulnerable (VU) on the IUCN Red List 2006. Because of grazing interference, over-hunting and poaching, the distribution area and population amount of G. subgutturosa have reduced sharply since recent decades. In order to conserve this species, researchers around the world have done a great deal of studies on its ecology and biology. This paper summarized the main results of these studies from the aspects of morphology, taxology, population ecology, habitat selection, seasonal migration, feeding ecology, physiology, reproduction, and endangered causes and conservation strategy, and put forward some suggestions for the further study on G. subgutturosa.
