Population density dynamics of the Phrynocephalus mystaceus mystaceus (Reptilia, Agamidae) intrapopulation group on the Sarykum sandy massif during the breeding season

Our study of the Phrynocephalus mystaceus mystaceus (Pallas, 1776) intrapopulation group on the Sarykum sand massif was carried out during the breeding seasons (1^st ten days of May) in 2021 – 2024. In this part of the habitat, the species forms local groups with a very high population density (from 72.9 to 95.7 ind. / ha). Apparently, this is due to the island position of the population on the Sarykum.

Reptile communities of desert landscapes and analysis of the herpetofauna of Southeastern Kazakhstan

Authors: Bondarenko D. A., Dujsebayeva T. N.

We used the route method to carry out quantitative counts of reptiles in nine regions of Southeastern Kazakhstan. The results yielded data on the population density of reptiles in fourteen habitats. We observed the greatest diversity of species and the largest number of reptiles in sandy deserts. Both measures were much smaller in loamy plains and low mountains. In desert habitats, the Central Asian tortoise Agrionemys horsfieldii and the rapid racerunner Eremias velox were more common than other species.

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.

REPTILE COMMUNITIES OF THE KARAKALPAKIAN USTYURT (UZBEKISTAN)

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.
