Large-scale patterns of Amazonian biodiversity have until now been obscured by a sparse and scattered inventory record. Here we present the first comprehensive spatial model of tree α-diversity and tree density in Amazonian rainforests, based on the largest-yet compilation of forest inventories and bolstered by a spatial interpolation technique that allows us to estimate diversity and density in areas that have never been inventoried. These data were then compared to continent-wide patterns of…

By using the seven forest inventories complemented with trait and inventory data collected elsewhere, two dominant gradients in tree composition and function across the Amazon are shown, one paralleling a major gradient in soil fertility and the other paralleled a gradient in dry season length.

We analyze forest structure, diversity, and dominance in three large-scale Amazonian forest dynamics plots located in Northwestern (Yasuni and Amacayacu) and central (Manaus) Amazonia, to evaluate
Dominant tree species drive beta diversity patterns in western Amazonia.

The results reveal that dominant species play a key role in structuring western Amazonian tree communities, which in turn has important implications, both practically for designing effective protected areas, and more generally for understanding the determinants of beta diversity patterns.

SPATIAL VARIATION IN TREE SPECIES COMPOSITION ACROSS TROPICAL FORESTS: PATTERN AND PROCESS
OVERVIEW Understanding the causes of spatial variation in floristic composition is one of the overarching goals of plant ecology. This goal has been challenged by the difficulty of unfolding the
Drivers of tropical rainforest composition and alpha diversity patterns over a 2,520 m altitudinal gradient
• Environmental Science
Ecology and evolution

There are two well‐defined forest compositional zones on this gradient—lowlands 430–1,120 m asl and montane forests >2,150m asl—with a transitional zone at 1,400–1-600 m asL, where lowland tropical and montana holarctic species are found together.

There was a significant decrease in species richness with decreasing size of plateaus, and a significant decreases in the similarity in species composition with greater distance and climatic variation among sampling sites.

It is found that beta-diversity is higher in Panama than in western Amazonia and that patterns in both areas are inconsistent with the neutral model, suggesting that dispersal limitation, with speciation, influences species turnover.
