The paper presents the results of using multiplicative indices for species identification of polyploid green toads of Central Asia. Live adult individuals of Bufotes baturae (24 females and 17 males) from the territory of Tajikistan and B. pewzowi (14 females and 24 males) from Kazakhstan, Uzbekistan and Tajikistan were studied. The animals were caught in nature, measured and immediately released. The species belonging of the studied green toads was established by cytogenetic methods.

History of Central Asian tortoise Agrionemys horsfieldii (Testudinidae, Reptilia) harvesting in Uzbekistan, and its population impact

Authors: Bondarenko D. A.

The harvesting of the Central Asian tortoise has been a longstanding practice in Uzbekistan. Throughout the 1930s–1950s, this species was harvested to feed farm livestock and shepherd dogs, and during the World War II, tortoise meat was used to provide additional nutrition to the people. The 1960s marked the start of commercial trade in tortoises. The annual volumes of legal harvesting of wild tortoises started to grow in the late 1990s, and reached 85 thousand specimens per year by 2017.

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

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)

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.
