Sex-biased dispersal at different geographical scales in a cooperative breeder from fragmented rainforest.

Dispersal affects both social behavior and population structure and is therefore a key determinant of long-term population persistence. However, dispersal strategies and responses to spatial habitat alteration may differ between sexes. Here we analyzed spatial and temporal variation in ten polymorph...
