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)
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)
