Abstract
We present a model of a male-female evolutionary game on mate-locating beha viour. Two major mating systems are considered: "lek polygyny" (in which ma les aggregate to wait for females searching for males) and "searching polyg yny" (in which males search for females emerging or waiting for males). The model predicts that lek polygyny is favoured (i) when male survivorship du ring lekking is sufficiently higher than that during mate searching, (ii) w hen female survivorship while visiting a lek is sufficiently higher than at the emergence site, or (iii) when searching efficiency is higher at a lek than at an emergence site. Furthermore, the model shows that a reduction in the reproductive value of females later in the day, which prevents males f rom performing riskier mate-locating behaviour, can result in a change of m ating system. In addition, mixed mating systems can be realized as transien t states during this shift.
