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.

该项目旨在将联合收割机独特的长期数据与一种新的公民科学方法相结合，以寻求提供第一个完整的假设测试，即避免近亲繁殖可以导致哺乳动物和鸟类社会中最著名的模式之一--青少年何时分散以及分散多远的性别差异。扩散是一个至关重要的生态和进化过程，因为它影响种群的命运，也决定了个体与扩散者将度过余生。因此，它塑造了亲属之间相互合作或竞争的可能性，并决定了扩散者可以与之交配的个体群。
