Behavioral sensitivity to corticosterone in juveniles of the wall lizard, Podarcis muralis.

摘要: Reptiles exposed to stressful conditions respond with increases in plasma levels of corticosterone (CORT). The outcome such hormonal fluctuations can affect the organism's physiology and behavior; however, relatively few studies reptiles have progressed past effects stress on CORT. purpose this study was investigate CORT lizard behavior. We focused activity thermoregulation juveniles wall lizard, Podarcis muralis. Juveniles experimentally elevated concentrations showed a higher moving rate spent greater amount time moving. They also more being involved attempts escape from terrarium. This enhanced locomotor associated significant changes thermoregulatory behavior, as CORT-increased individuals had reduced than controls. same pattern results obtained nature under laboratory conditions. Thus, appear mediate an important trade-off between thermoregulation. To our knowledge, is first that effect has been examined.
