Sender–receiver dynamics in leafhopper vibrational duetting

摘要: A coordinated reciprocal exchange of acoustic signals (duetting) is common in arthropods relying on substrate-borne vibrational signalling. Communication between partners under evolutionary pressures resulting from ecological and sexual selection effects arising such dynamic interactions may influence the sender's receiver's mating success. We investigated female reply duration male mate-searching effort leafhopper Aphrodes makarovi which essential for successful location female. In a duet, beginning overlaps end call males evaluate only nonoverlapped reply. playback experiments we varied replies within natural range. The was negatively correlated with calling effort. By increasing her significantly reduce male's direct indirect costs associated signalling searching, thus, ultimately, affecting reproductive Males showed high adaptability behaviour when were short, searching shortened last section their advertisement calls. This strategy allows part to be longer irrespective its overall duration. Despite deceptively simple form, duetting entail more complex than just temporal coordination.
