N colonies: number of colonies in each analysis. i.e., those containing at least two same-sex individuals for single-sex analyses; N individuals: total number of individuals in each analysis; F_ST: the estimated amount of genetic variation among colonies; intra-colony r: the estimated level of relatedness within colonies; inter-colony r: the estimated level of relatedness among colonies. Significant differences between males and females are indicated by an asterisk. along with associated p value (alpha = 0.05) and degrees of freedom (df). IBD analyses for each of the six datasets are shown as regression of pairwise r on the logarithm of spatial distance (Rxy, as computed in Genalex, and blog, as computed in Spagedi) with the associated p-values
