Parent personality is linked to juvenile mortality and stress behavior in the arctic fox (Vulpes lagopus)
Abstract Life history theory predicts that individuals will differ in their risk-taking behavior according to their expected future fitness. Understanding consequences of such individual variation within a behavioral trait is crucial in explaining potential trade-offs between different traits and in...

Abstract Life history theory predicts that individuals will differ in their risk-taking behavior according to their expected future fitness.
