Reptiles of the Southwestern Tajikistan desert plains: Spatial distribution, population density and communities structure

Authors: Bondarenko D. A., Ergashev U. H.

Population density of reptiles in four desert areas of southwestern Tajikistan was estimated in spring 2018–2019. The structure of reptile communities in seven typical landscapes was described. The highest species diversity and population density were observed in sandy landscapes. Seven species of psammobionts formed the basis of these reptile communities.

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

Authors: Bondarenko D. A., Peregontsev E. A.

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.
