摘要: Plant communities are shaped by multiple factors along environmental gradients; however, studies limited on how filtering drives community composition and species richness tropical inselbergs. We evaluate the influence of altitude climatic variables related to temperature precipitation plant Brazilian assume as a premise that both climate would induce changes at local level. used inventory data from 370 sampling units across four inselberg sites in Atlantic Forest Espirito Santo State, south-eastern Brazil. tested univariate multivariate effects with models. Differences between inselbergs were evaluated using sample-based estimate rarefaction extrapolation curves. In addition, differences taxonomic beta diversity examined via novel frequency-based metrics. A contrasting pattern was observed sites, south being wet compared dry conditions found northern sites. Species showed similar within regional sites; there marked regions. significant among higher values southern than multi-model comparison significantly influenced explained more variance This finding suggested could act some extent these inselbergs; better predictor
