Species Trait Data for Regression Analysis

Species trait data for each of the 768 paired carnivores in all 13 study areas. Species codes (Spp1 and Spp2) were derived from the first two letters of the genus and species name (e.g., EIBA = Eira barbara). Appendix S2 contains the full list of species examined in this study. We summarized the categorical variables of diet, temporal activity pattern, social structure, body size and taxonomic similarity in two ways. For the first coarse comparison method (e.g., DietCovSimple), we compared species with differing trait values (e.g., when species A | B are strict carnivore | omnivore) to those where pairs shared the trait value (e.g., strict carnivore | strict carnivore). In other words, species pairs were either labeled the ‘same’ or ‘different’ for all categorical variables of interest. For the fine-scale trait comparison (e.g., DietCov), species pairs were categorically valued for all combinations of a trait (e.g., strict carnivore | strict carnivore = 1, strict carnivore | omnivore = 2, strict carnivore | insectivore = 3, etc.). We also characterized the mean weight ratio (heavier:lighter species, MeanBodySize) between two species, including it as a log-transformed continuous variable (logMeanBodySize). We also include the observed number of carnivore species in each study area (NumSpecies) and the study area’s climate as determined by the Köppen-Geiger climate classification system (Climate). Finally, this file also includes the estimated Species Interaction Factor (SIF), the standard deviation of SIF (sd), and the log-transformed SIF values (logSIF)

Data from: Ecological correlates of the spatial co-occurrence of sympatric mammalian carnivores worldwide

The composition of local mammalian carnivore communities has far-reaching effects on terrestrial ecosystems worldwide. To better understand how carnivore communities are structured, we analyzed camera trap data for 108,087 trap days across 12 countries spanning 5 continents. We estimate local probabilities of co-occurrence among 768 species pairs from the order Carnivora and evaluate how shared ecological traits correlated with probabilities of co-occurrence. Within individual study areas, species pairs co-occurred more frequently than expected at random. Co-occurrence probabilities were greatest for species pairs that shared ecological traits including similar body size, temporal activity pattern, and diet. However, co-occurrence decreased as compared to other species pairs when the pair included a large-bodied carnivore. Our results suggest that a combination of shared traits and top-down regulation by large carnivores shape local carnivore communities globally
