Spatial coevolution of males and females

Populations are usually not panmictic, where every individual is equally likely to meet any other individual. I will present two modelling efforts to understand how this fact impacts (a) mate choice and (b) the effect of sexual dimorphism on species coexistence. The first model will look at local adaptation and how it might help us understand female choice for condition-dependent male traits. The second model comments on problems of coexistence that arise from sexual conflict theory. Males often deplete resources more (per capita) than do females, often without directly contributing to raising new offspring. I will reflect on the effects this has on the coexistence question when species additionally differ in which sex is the more dispersive sex.
