Seasonal journeys between breeding and non-breeding habitat are undertaken by a diverse array of animals. Parallel developments in tracking and genomic methods are enabling finer resolution of these movements and their role in the evolutionary process. Evidence from allopatric and co-occurring breeding populations indicates that variation in migratory behavior is often associated with genetic differentiation. While assortative mating and selection against hybrids due to divergent migratory phenotypes can contribute to reproductive isolation, the details of these mechanisms remain unclear. Here we identify gaps in our understanding of the role of seasonal migration in the speciation process and propose a framework to test the relative significance of reproductive barriers associated with variation in migratory behavior that might underlie population differentiation.

季节性移民在人口分化和生殖隔离中的作用

繁殖和非繁殖栖息地之间的季节性旅行是由各种各样的动物进行的。跟踪和基因组方法的并行发展正在使这些运动及其在进化过程中的作用得到更好的解决。来自异源和共生繁殖种群的证据表明,迁徙行为的变化通常与遗传分化有关。尽管由于迁移表型不同而进行的杂种交配和选择可能有助于生殖隔离,但这些机制的细节仍不清楚。
