Variation in wood density determines spatial patterns inAmazonian forest biomass
Uncertainty in biomass estimates is one of the greatest limitations to models of carbon flux in tropical forests. Previous comparisons of field‐based estimates of the aboveground biomass (AGB) of…
Drought Sensitivity of the Amazon Rainforest
Records from multiple long-term monitoring plots across Amazonia are used to assess forest responses to the intense 2005 drought, a possible analog of future events that may accelerate climate change through carbon losses and changed surface energy balances.
Beta-Diversity in Tropical Forest Trees
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.

The results presented here suggest that the total biomass of these plots has on average increased and that there has been a regional-scale carbon sink in old-growth Amazonian forests during the previous two decades.
Global Conservation Significance of Ecuador's Yasuní National Park
Yasuní has outstanding global conservation significance due to its extraordinary biodiversity and potential to sustain this biodiversity in the long term because of its large size and wilderness character, and likelihood of maintaining wet, rainforest conditions while anticipated climate change-induced drought intensifies in the eastern Amazon.
DOMINANCE AND DISTRIBUTION OF TREE SPECIES IN UPPER AMAZONIAN TERRA FIRME FORESTS
Amazonian forests are the largest and most diverse in the tropics, and much of the mystery surrounding their ecology can be traced to attempts to understand them through tiny local inventories. In…
Hyperdominance in the Amazonian Tree Flora
The finding that Amazonia is dominated by just 227 tree species implies that most biogeochemical cycling in the world’s largest tropical forest is performed by a tiny sliver of its diversity.
The regional variation of aboveground live biomass in old‐growth Amazonian forests
The biomass of tropical forests plays an important role in the global carbon cycle, both as a dynamic reservoir of carbon, and as a source of carbon dioxide to the atmosphere in areas undergoing…
Continental-scale patterns of canopy tree composition and function across Amazonia
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.
Relationships among ecologically important dimensions of plant trait variation in seven neotropical forests.
The dimensions represented by SLA, seed/fruit size and leaf size were essentially independent and thus conveyed largely independent information about plant strategies, and to a lesser extent the same was true for plant height and WD.
