Appendix S2 Locations of sites included and excluded from our study
Black markers indicate sites included in this study. Gray markers indicate the presence of 1–3 primate species (excluded from study). Open circles indicate a mammal community with no primates. Of the 203 total sites for which we compiled African mammal data, 134 sites had 4 or more primate species (we excluded 3 of these sites for reasons described in the methods). An additional 22 sites had 3 primate species, 12 sites had 2 primate species, 16 sites had 1 primate species, and 19 sites had 0 primate species.
Appendix S3 Cluster analysis dendrogram
Region assignments follow each site name abbreviation and correspond to Region IDs in Table I.
Appendix S4 Partial Mantel test results with alternative similarity index (βsim index) Partial Mantel tests examine the relative strength of environmental filtering and dispersal limitation in each region based on the strength of the correlation (r) between community similarity (βsim index) and environmental distance or geographic distance, respectively. Values are missing for the East Zambezian because of low variability in species richness between sites that precludes partial Mantel tests with the βsim index. Bold font indicates a significant predictor of primate community similarity (P ≤ 0.05).
