title: Data from: Within-group relatedness is correlated with colony-level social structure and reproductive sharing in a social fish.

description: In group-living species, the degree of relatedness among group members
 often governs the extent of reproductive sharing, cooperation and conflict
 within a group. Kinship among group members can be shaped by the presence
 and location of neighbouring groups, as these provide dispersal or mating
 opportunities that can dilute kinship among current group members. Here,
 we assessed how within-group relatedness varies with the density and
 position of neighbouring social groups in Neolamprologus pulcher, a
 colonial and group-living cichlid fish. We used restriction
 site-associated DNA sequencing (RADseq) methods to generate thousands of
 polymorphic SNPs. Relative to microsatellite data, RADseq data provided
 much tighter confidence intervals around our relatedness estimates. These
 data allowed us to document novel patterns of relatedness in relation to
 colony-level social structure. First, the density of neighbouring groups
 was negatively correlated with relatedness between subordinates and
 dominant females within a group, but no such patterns were observed
 between subordinates and dominant males. Second, subordinates at the
 colony edge were less related to dominant males in their group than
 subordinates in the colony centre, suggesting a shorter breeding tenure
 for dominant males at the colony edge. Finally, subordinates who were
 closely related to their same-sex dominant were more likely to reproduce,
 supporting some restraint models of reproductive skew. Collectively, these
 results demonstrate that within-group relatedness is influenced by the
 broader social context, and variation between groups in the degree of
 relatedness between dominants and subordinates can be explained by both
 patterns of reproductive sharing and the nature of the social landscape.
