Glucocorticoid responses to adrenocorticotropic hormone (ACTH) in red-sided garter snakes, Thamnophis sirtalis Effects of sex and season
Meeting Abstract 103.5 Tuesday, Jan. 7 09:15 Glucocorticoid responses to adrenocorticotropic hormone (ACTH) in red-sided garter snakes, Thamnophis sirtalis: Effects of sex and season DAYGER, CA*; LUTTERSCHMIDT, DI; Portland State University cdayger@pdx.edu Many studies have demonstrated that vertebrate stress responses are often context-dependent. We recently showed that low body condition is associated with greater sensitivity to capture […]
