Short summary
By genotyping faecal samples from unhabituated gorillas collected over 5 years in Loango National Park, Gabon, we investigated gorilla group composition, social structure and dispersal. We identified 85 individuals, two group dissolutions, one group formation and the movement of 13 gorillas between groups. We also found that females are found in groups containing their female kin more often than expected by chance, suggesting that dispersal may not impede female kin associations in gorillas.
