Most theoretical models on evolution of male secondary sexual characters and female
preferences for these characters suggest that the male characters evolve in response to …

Abstract Female mate preferences are a major cause of diversity and elaboration in male
sexual traits. Here we characterize the shape of female preference functions for pulse length …

Selection on advertisement signals arises from interacting sources including female choice,
