The thermal biology of the Phrynocephalus guttatus (Gmelin, 1789) in the Astrakhan region
Thermophysiological (maximum 41,3 °С and minimum 35,7 °С temperature of the full activity, mode thermostabilization range 38–40 °С, mode is 38,6 °C) and thermoecological (voluntary maximum and minimum, preferred temperatures, night temperatures 10–22 °С) activity indices were determined in Ph. guttatus in May. Four general forms of behavior were observed: warming (22,5–36,1 °C), thermostabilizing behavior (35,7–41,0 °C), voluntary overheat (36,0–41,3 °С) and cooling (37,8–29,3 °C). Refs 7. Figs 2.
