The Amazon rain forest sustains the world's highest tree diversity, but it remains unclear why some clades of trees are hyperdiverse, whereas others are not. Using dated phylogenies, estimates of current species richness and trait and demographic data from a large network of forest plots, we show that fast demographic traits--short turnover times--are(More)
Aim To examine variation in the phylogenetic diversity (PD) of tree communities across geographical and environmental gradients in Amazonia. Location Two hundred and eighty-three c. 1 ha forest inventory plots from across Amazonia. Methods We evaluated PD as the total phylogenetic branch length across species in each plot (PDss), the mean pairwise(More)
Lineages tend to retain ecological characteristics of their ancestors through time. However, for some traits, selection during evolutionary history may have also played a role in determining trait values. To address the relative importance of these processes requires large-scale quantification of traits and evolutionary relationships among species. The(More)
In the last 20 years, the Mocotíes watershed in the Venezuelan Andes has experienced an intense process of land-use change, with natural forests being replaced by “sun grown coffee” (Coffea arabica) monocultures in sites of high slope, increasing risk conditions and the vulnerability of people living in lower parts of the watershed. Using a local-scale(More)
