Remotely sensed tree height and density explain global gliding vertebrate richness

In vertebrates, gliding evolved as a mode of energy‐efficient locomotion to move between trees. Gliding vertebrate richness is hypothesised increase with tree height and decrease density but empirical evidence for this scarce, especially at global scale. Here, we test the ability explain species vertebrates globally compared all while controlling biogeographical climatic factors. We compiled database 193 amphibians, mammals reptiles created maps from extent‐of‐occurrence range maps. paired spatial estimates regions (BGRs) covariates account ecological historical differences among regions. used univariate linear multivariate generalised mixed‐effect models evaluate relationships density, interaction both variables. found that increased significantly height, results alone indicated mixed responses different BGRs. Mixed‐effect mirrored these combined, also revealing response denisyt reptiles. Richness – non‐gliding lesser rate than indicating greater influence forest structure on patterns vertebrates. Our support hypotheses stating in tall forests trees, provide further importance distribution
