An account of the activity of the secret toadhead agama (Phrynocephalus mystaceus mystaceus Pall. 1776) during assessments of its population
The detailed study of the activity of the Phrynocephalus mystaceus mystaceus population in Astrakhan semi-deserts showed that almost all resident lizards had some rest periods (1–4 days), when they do not emerge on the surface. The account of the lizards’ activity allows proposing some correcting coefficient, which is 1.88. This coefficient should be used to obtain more precise data on the population number based on one-day registrations. Refs 9. Tables 3.
