ON POSSIBLE ESTIVATION OF PHRYNOCEPHALUS HELIOSCOPUS (PALLAS, 1771) AND EREMIAS ARGUTA (PALLAS, 1773) IN THE ALTAI REGION

Authors: Krymov N. G.

Summer counts of Phrynocephalus helioscopus (Pallas, 1771) and Eremias arguta (Pallas, 1773) were conducted in the Altai Region during April - September, 2016. A sharp decline in the activity of lizards in June and July was noted, due to the high temperatures and dry weather. As a result of excavation of some burrows, lizards in a non-active state were found. The possibility of summer hibernation (estivation) of the species is considered.
