Crayfish females eavesdrop on fighting males before choosing the dominant mate

Popis výsledku v původním jazyce

Identifying the traits that influence mate choice is a major challenge in behavioral ecology and evolutionary biology. Male dominance often conditions mating decisions by females, but how the hierarchical status of potential mates is assessed remains poorly understood. Males of the crayfish P. clarkii also often engage in intra-sexual fights during the reproductive season in the presence of females. The winners are expected to be favored by female crayfish. There was hypothesized that, before making a decision between two apparently identical males, females should be allowed to witness their agonistic interactions. To test this hypothesis, were compared the responses of bystander and na?ve females towards a dyad of males (dominant/subordinate). The results are clear in showing that eavesdropping on agonistic interactions improves the female?s ability to recognize the dominant male over the subordinate. In fact, bystander females visited the dominant male more often, remained in his pro
