Can inbreeding avoidance cause the evolution of sex-biased dispersal? (ARC Discovery Grant)

Dispersal is a critically important ecological and evolutionary process, as it influences the fate of populations, and also determines the individuals with which a disperser will spend the remainder of its life. It therefore shapes the likelihood that kin will interact to cooperate or compete, and determines the pool of individuals with which the disperser can mate. In this proposal we will combine unique long-term data with a novel Citizen Science approach to provide the first complete test of the hypothesis that inbreeding avoidance can cause one of the best known patterns in mammal and bird societies - sex differences in when and how far juveniles disperse.
