ABSTRACT The Chromolaena congesta complex (Asteraceae, Eupatorieae) presents a difficult challenge for biodiversity researchers due to the intertwined connections of its species and the difficulty of establishing morphological boundaries. In this stu

We assessed the effectiveness of a protected area (PA) network in representing tree taxonomic and phylogenetic uniqueness in subtropical Atlantic Forests (Rain, Mixed and Seasonal Forests). Using a network of plots distributed over ∼95,000 km2 in s

The metacommunity framework offers a possibility to better understand how ecological processes influence patterns of species diversity along environmental gradients. The species-sorting perspective predicts that community composition varies in respon

We investigated how cactus diversity at the regional level (γ-diversity) is distributed into within-unit diversity (α-diversity) and among-unit diversity (β-diversity), and analyzed the contribution of dissimilarity due to species replacement (tur

We investigated the relative importance of various natural and human-related environmental factors on the structure of 36 cacti communities occurring on rocky outcrops in southern Brazil grasslands. Outcrops were embedded in either open grasslands gr
