Can inbreeding avoidance cause the evolution of sex-biased dispersal?

该项目旨在将独特的长期数据与一种新的公民科学方法相结合，试图对近亲繁殖避免可能导致哺乳动物和鸟类社会中最著名的模式之一--幼崽何时分散以及分散到多远--的性别差异进行首次完整的检验。扩散是一个极其重要的生态和进化过程，因为它影响着种群的命运，也决定着分散者将与之共度余生的个体。因此，它决定了亲属相互作用以合作或竞争的可能性，并决定了分散者可以与之交配的个体池。

This project aims to combine unique long-term data with a novel Citizen Science approach to seek 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. 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.
