In many closely related taxa, females exhibit few obvious visual differences and males might have to attend to chemical cues in mate recognition, a possibility that has rarely been explored in vertebrates. Here, we examine male species recognition via odor cues in the swordtail fish, Xiphophorus birchmanni. In dichotomous choice experiments...[Show more]
