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

Description

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.
