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