REPTILE COMMUNITIES OF THE KARAKALPAKIAN USTYURT (UZBEKISTAN)

Terrestrial route counts of reptiles in 24 localities of the plateau Ustyurt were carried out in 2007 - 2008. 474 individuals of 15 species were found along a total of 243.5 km passed. Based on the results of our survey, the reptile population structure has been clarified in 12 landscapes. The low specific diversity and population density of reptiles were observed everywhere. 2 to 8 species with a population density of 1.9 - 8.4 individuals per ha were found in certain landscapes. In terms of abundance, the reptiles belonged to rare or common species.

DISTRIBUTION OF THE CENTRAL ASIAN TORTOISE AGRIONEMYS HORSFIELDII (GRAY, 1844) IN UZBEKISTAN (RANGE, REGIONAL AND LANRSCAPE DISTRIBUTION, POPULATIONS DENSITY)

The Central Asian tortoise distribution in Uzbekistan is described on the basis of our analysis of findings at 287 localities. All these localities with their locations have been mapped. The history of the propagation and formation of the habitat of the species is provided. It has been revealed that the tortoise is widely settled in desert landscapes. The area of its habitat is 67% of the territory of the republic (about 300,000 sq. km). However, the territory with higher population densities (> 10 animals per ha) occupies about 0.6% of this territory.
