Abstract

When members of the same population follow distinct migration routes, a migratory divide can arise. Could differences in migratory strategies contribute to genetic differentiation and possibly speciation? In this study, Turbek et al. combine genomic data, stable isotopes, and geolocators to characterize a migratory divide between two subspecies of the barn swallow (Hirundo rustica). Their findings set the stage for further analyses into the genetic basis of migratory behavior.

摘要

当同一种群的成员遵循不同的迁徙路线时，就可能出现迁徙分化。迁徙策略的差异会导致基因分化并有可能引发物种形成吗？在这项研究中，图尔贝克等人结合基因组数据、稳定同位素和地理定位器，来描述家燕（Hirundo rustica）两个亚种之间的迁徙分化。他们的研究结果为进一步分析迁徙行为的遗传基础奠定了基础。
