On the Ecology of the Desert Sand Boa Eryx milliaris (Reptilia, Boidae) in Kalmykia

The paper contains data on the inhabitation, abundance and temperature selectiveness of the desert sand boa in Kalmykia. Bioclimatic variables influencing its range are also analyzed by modeling with the Maxent software. Two models were used in our analysis, built on 19 standard bioclimatic variables and on a shortlist after the removal of correlated variables. The body temperature of the desert sand boa varied from 12 to 33°С. Its population level stays rather high in Kalmykia, up to two specimen per ha on sand hills of the Chernozemelskiy district.

DISTRIBUTION DATA OF ROCK LIZARDS FROM THE DAREVSKIA (PRATICOLA) COMPLEX (SAURIA: LACERTIDAE)

The paper presents analysis of the distribution of Darevskia praticola praticola, D. praticola loriensis, D. p. hyrcanica, and D. pontica in the Caucasus. GIS modeling (Maxent 3.3.3k) was used. Analysis of the obtained GIS maps of distribution has allowed us to locate territories with maximum occurrence probabilities of these taxa.
