Molekulare Grundlagen des Vogelzugs

Migration is a complex behavior of which a significant proportion is genetic. Which genes and epigenetic changes underpin migratory behavior remains largely unknown, but a revolution of sequencing technology, analytical approaches, and functional genomic tools promises rapid advances. We summarize our current understanding of the (epi)genetic architecture of seasonal traits and outline our vision of how technical developments and integrative approaches could be employed to identify and functionally validate candidate genes and regulatory elements in migratory species.
