Extreme philopatry and genetic diversification at unprecedented scales in a seabird

Abstract Effective conservation requires maintenance of the processes underlying species divergence, as well as understanding species’ responses to episodic disturbances and long-term change. We explored genetic population structure at a previously unrecognized spatial scale in seabirds, focusing on...
