Figure 1.

Boxplots showing pairwise relatedness values (Li relatedness index, Li et al. 1993) among adult females (FF), between adult females and juveniles (FJ), among juveniles (JJ), between adult males and juveniles (MJ), among adult males (MM) and between adult females and adult males (MF), (a) trapped in the same colony and (b) trapped in the same locality, but not the same colony. Boxes represent the interquartile range, bars within boxes are median values and whiskers indicate the 10th and 90th percentiles. Zero line indicates the theoretical pairwise relatedness value between two individuals taken at random in the population. Dots indicate mean value. Numbers of pairwise data are also indicated. In the first graph, the combined p-value of the permutations tests of individuals among colonies is also provided (*p < 0.05; ***p < 0.001).
