Long-term anthropogenic disturbances alter plant species composition in the Southern Atlantic forest.

ABSTRACT: It is well known that anthropogenic impacts reshape species composition and cause biodiversity loss, altering tree diversity patterns in natural forests. Here, we use a robust database encompassing three forest formations in the subtropical Atlantic Forest to determine how environmental conditions and anthropogenic impacts affect diversity patterns. We compare alpha and beta-diversity indexes using generalized dissimilarity models (GDM) within and between forest formations and two successional stages (intermediate and advanced). We found that beta-diversity across all forest formations and successional stages was mainly explained by species richness (53.3%), followed by environmental factors (26.9%), including precipitation seasonality and mean annual temperature, geographic distance (7.6%
