Selection against immigrants in wild seabird populations

International audience Immigration is a major demographic parameter shaping population dynamics and is an importantdriver of eco-evolutionary patterns, but the fitness consequences for individuals following theirsettlement to a new population (immigrants) remain poorly tested in wild animal populations,particularly among long-lived species.
