title: Data from: Interactions between plants and primates shape community diversity in a rainforest in Madagascar

description: 1. Models of ecological community assembly predict how communities of
 interacting organisms may be shaped by abiotic and biotic factors.
 Competition and environmental filtering are the predominant factors
 hypothesized to explain community assembly. 2. This study tested the
 effects of habitat, phylogenetic and phenotypic trait predictors on
 species co-occurrence patterns and abundances, with the endemic primates
 of Madagascar as an empirical system. 3. The abundance of 11 primate
 species was estimated along gradients of elevation, food resource
 abundance, and anthropogenic habitat disturbance at local scales in
 southeast Madagascar. Community composition was compared to null models to
 test for phylogenetic and functional structure, and the effects of
 phylogenetic relatedness of co-occurring species, their trait similarity,
 and environmental variables on species' abundances were tested using
 mixed models and quantile regressions. 4. Resource abundance was the
 strongest predictor of community structure. Where food tree abundance was
 high, closely related species with similar traits dominated communities.
 High elevation communities with lower food tree abundance consisted of
 species that were distantly related and had divergent traits. Closely
 related species had dissimilar abundances where they co-occurred,
 partially driven by trait dissimilarity, indicating character
 displacement. 5. By integrating local-scale variation in primate community
 composition, evolutionary relatedness and functional diversity, this study
 found strong evidence that community assembly in this system can be
 explained by competition and character displacement along ecological
 gradients.
