Eco-Evolutionary Dynamics of Migration
When, where, how and why do animals migrate? These answers may vary with species and their degree of sociality. In most species, individuals may migrate alone, unaided by conspecifics. These individuals may have little or no opportunity for cultural transmission of migratory behavior and thus should rely instead – particularly during their first migratory journey - on endogenous, inherited spatiotemporal migration programs encoding when, where, and how far to migrate. Despite decades of research on songbird migration, our understanding is still limited to what degree migration programs are hard-coded or flexible when faced with environmental variation and about the evolution and maintenance of bird migration in general. Our goal is to examine the strategies of migratory and sedentary birds from various perspectives: ecology, evolution, physiology and genetics.
