Thermobiology of the common viper (Vipera berus, Reptilia, Serpentes) in the Volga basin

The research in herpetology at the chair of zoology of the Perm State Pedagogical University was begun in 1996. The main interests lie within the sphere of studying reptile thermoadaptation, the electrical activity of heart in varying temperature conditions, morphology and blood biochemistry. A considerable amount of data about the thermobiology of the common viper in the Volga basin was gathered. According to the main temperature axes, several differences between the light and black morphs were discovered.
