Pairwise social and genetic predictors of Bray–Curtis dissimilarity among Verreaux's sifaka inhabiting Kirindy Mitea National Park. Posterior mean, 95% credible interval (95% CIs), and p-value based on Markov chain Monte Carlo sampling for fixed-effect parameters. Baseline relatedness (not related) is not shown. Individual identity within each pair was included as a random effect. Bolded relationships are significant at p < 0.05.

|---|---|---|---|---|---|
| group membership Npairs = 167 DIC: −486.4 |
intercept | 0.47 | (0.44, 0.5) | <5×10−5 | |
| the same group | −0.11 | (−0.14, −0.09) | <5×10−5 | pairs in the same social group have less dissimilar microbiota | |
| related | 0.01 | (−0.02, 0.04) | 0.57 | no significant correlation | |

intercept | 0.34 | (0.3, 0.38) | <5×10−5 | |
| network path length | 1.7×10−5 | (1.23×10−5, 2.19×10−5) | <5×10−5 | pairs that are farther apart in the social network have more dissimilar microbiota | |
