Seasonal and sex differences in responsiveness to adrenocorticotropic hormone contribute to stress response plasticity in red sided garter snakes (Thamnophis sirtalis parietalis)
... As in many vertebrates, hormonal responses to stress vary seasonally in red-sided garter snakes (Thamnophis sirtalis parietalis). For example, males generally exhibit reduced glucocorticoid responses to a ...
