The Mongolian gazelle (Procapra gutturosa Pallas, 1777) and five domestic herbivores share the steppe plants. The desertification of the steppe induced by overgrazing is related to the activities of the community of the large herbivore. A plant-herbivore data matrix obtained by cuticular analysis has made it possible to estimate the impact of trophic(More)
A survey of steppe ecosystems of eastern Mongolia, including the territory of the Eastern Steppe Station Tumén-Tsogt (in Sukhebator district), was conducted in 2008 under the program “Mongolian Ecosystem Monitoring” with the support of the Joint Russian-Mongolian Complex Biological Expedition of the Russian Academy of Sciences and Mongolian Academy of(More)
The amount of phytomass removed by a complex of livestock (horses, cattle, sheep, and goats) and wild ungulates (Mongolian gazelle Procapra gutturosa Pall.) grazing in plain and mountain pastures of eastern Mongolia has been estimated by taking account of feces deposited by these animals. The results show that at an animal density of up to 30 head/km2, the(More)
The features of the present distribution and cenotic association of ephedra (Ephedra sinica Stapf.) in the arid steppe ecosystems of Central and Eastern Mongolia are studied on the basis of data of large-scale investigations performed at the Bayan-Unzhul and Tumentsogt stations within the framework of a Joint Russian-Mongolian complex biological expedition(More)
This paper deals with food selectivity in large herbivores of Eastern Mongolia, its factors, and their impact on the herbivore community structure. It is shown that, due to the degradation of vegetation, all studied herbivores display a significant selectivity level conditioned by their morpho–physiological features and spatial distribution. The selectivity(More)
