Некоторые черты термобиологии разноцветной ящурки Eremias arguta (Gmelin, 1789) и круглоголовки-вертихвостки Phrynocephalus guttatus (Gmelin, 1789) (Squamata, Reptilia) при совместном обитании в Северном Прикаспии

Abstract

The paper presents data on temperatures of the body and the selected substrate for the steppe-runner and the spotted toadhead agama. Thermal preferences and modal classes for both species were determined, and interspecies differences were analyzed. Significantly higher average temperatures were found in the steppe-runner, while the maximum voluntary temperatures are higher in the spotted toadhead agama. These features are associated with the biotopic confinement of species. Representatives of both species, even in the spring, have a lower body temperature compared to the environment, which is achieved due to behavioral thermoregulation.
