The role of corticosterone and toxicity in the antipredator behavior of the Rough-skinned Newt ( Taricha granulosa )

Highlights • Newts performing antipredator behavior have elevated CORT levels. • The duration of time engaging in the behavior is not correlated with CORT levels. • Neither CORT nor behavior is associated with levels of toxin in newt skin. • Exogenous application of CORT and ACTH suppress antipredat...

Zusammenfassung:	Highlights • Newts performing antipredator behavior have elevated CORT levels. • The duration of time engaging in the behavior is not correlated with CORT levels. • Neither CORT nor behavior is associated with levels of toxin in newt skin. • Exogenous application of CORT and ACTH suppress antipredator behavior. • In CORT-treated animals, CORT is correlated with time in antipredator behavior.
