Mate limitation causes sexes to coevolve towards more similar dispersal kernels

摘要: Sex-specifi c dispersal behavior has been documented in a wide range of diff erent species. Avoidance inbreeding and kin competition as well benefi ts philopatry have invoked explanations for these patterns. All factors have, however, focused on explaining why ers between the sexes. In this paper, we make case that causes an increase spatial variability sex ratio which can reduce local availability mates, thus feed back to infl uence evolution sex-specifi lead more, rather than less, similar We investigate mechanism two models, fi rst conceptually simple showing coevolutionary eff ect arises, second individual-based model where population explicit space with implemented kernels. While our is not expected completely remove sex-bias dispersal, it act alongside other selection pressures such biases. Our shows one selective opposite sex, without implementing avoidance or differential costs dispersal.
