Phylogenetic tree (following Brady [7]) of all 13 army ant species for which paternity data is available so far.

Data on colony size, observed and effective paternity frequency (k_obs and m_e), effective-number-index of paternity skew (S) and inbreeding coefficient (F_IS) are given next to the tree. Colony size is represented by the average approximation of the number of workers in normal mature colonies as given in the literature. k_obs and m_e are the means given in this study or in the literature, from which S was calculated [47], [64]. Mean F_IS is also taken from this study or the literature (asterisks mark significance). Species abbreviations, as used in the following figure legends, are given in brackets behind species names. n/a, data not available. ¹ Data on these species are listed for the sake of completeness, but have not been used in this study because m_e estimates were either not published, higher than the respective k_obs, or assumed to be underestimated [16], so that in these cases the S-index could not be calculated or would have been biased. ² Paternity and inbreeding data on these species are the result of this study.
