Large-scale patterns of genetic variation in a female-biased dispersing passerine: the importance of sex-based analyses.

Dispersal affects the distribution, dynamics and genetic structure of natural populations, and can be significantly different between sexes.However, literature records dealing with the dispersal of migratory birds are scarce, as migratory behaviour can notably complicate the study of dispersal.We used the barn swallow Hirundo rustica as model taxon
