Resumo

One of the most fundamental predictions for secondary succession involves the gradual replacement of stress-resistant species by others that are better competitors under late succession conditions. However, it remains unclear how widespread this replacement is and whether it holds across regional types of recovering forests. Here, we identify these species groups and how they replace each other during the succession of the main Atlantic Forest subtypes (i.e. Araucaria Forest, Rainforest and Seasonal Forest), using a dataset containing species abundance data from 497 tree communities spread across this biodiversity hotspot. We also test whether the association with successional stages can be explained by species taxonomy or functional traits. Species composition varied significantly both between and within successional stages. Among the 2749 surveyed species, 237 were identified as disturbance-opportunists and 650 as disturbance-sensitive. Species turnover was low, as most species (61.38%) had low abundances and frequencies (<5% within subtypes), regardless of successional stage. Additionally, 249 species remained abundant across all successional stages, which encompassed 45.8% of the surveyed trees. The relationship between species and successional stages showed little correlation with taxonomy. Furthermore, traits, such as specific leaf area, maximum height, wood density and seed mass, were highly variable within species groups and unfit to predict species suitability across successional stages. Synthesis. We show that species replacement along Atlantic Forest succession only applies to a restricted fraction of species and that species reassembly is variable across time and space. Overall, our study illustrates the importance of regional measurements of species sensitivity to anthropogenic disturbance in assessing tropical forest succession. (AU)
