Fig. S1. Results of simple linear regressions showing the linear dominance hierarchies of all females in the three study groups (Group 1a: N = 9; Group 1b: N = 7, Group 2: N = 5), calculated using normalized David’s scores based on the dyadic dominance index, corrected for chance. Dashed circles indicate the separation of dominance classes, with individuals in the left hand circle being ‘high’ rank and individuals in the right-hand circle being ‘low’ rank.
Table S1. Information about group composition for the three study groups at Lola Ya Bonobo Sanctuary. Information about their identity code, name, age and dominance rank is indicated. Individuals arrived as wild juveniles/infants, thus age ranges are approximate estimations based on veterinary assessment. Dependent infants are indicated in super-script next to their mother’s name, with their sex in brackets.
Table S2. Results from Matman tests for linearity of dominance hierarchies calculated for the three bonobo groups in this study.
Table S3. Mean values (+ SDs) for acoustic parameters for analysis of homosexual versus heterosexual copulation calls for 7 bonobo females.
