Behavioral responses of the European mink in the face of different threats: conspecific competitors, predators, and anthropic disturbances

Abstract Prey species assess the risk of threat using visual, olfactory, and acoustic cues from their habitat. Thus, they modify their behavior in order to avoid encounters with competitors, predators, and human disturbances that endanger their fitness. European mink (Mustela lutreola) is a critical...
