A Large and Persistent Carbon Sink in the World’s Forests
The total forest sink estimate is equivalent in magnitude to the terrestrial sink deduced from fossil fuel emissions and land-use change sources minus ocean and atmospheric sinks, with tropical estimates having the largest uncertainties.
Extinction risk from climate change
Estimates of extinction risks for sample regions that cover some 20% of the Earth's terrestrial surface show the importance of rapid implementation of technologies to decrease greenhouse gas emissions and strategies for carbon sequestration.
TRY – a global database of plant traits
The improved availability of plant trait data in the unified global database is expected to support a paradigm shift from species to trait-based ecology, offer new opportunities for synthetic plant trait research and enable a more realistic and empirically grounded representation of terrestrial vegetation in Earth system models.
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…
Increasing carbon storage in intact African tropical forests
Taxon-specific analyses of African inventory and other data suggest that widespread changes in resource availability, such as increasing atmospheric carbon dioxide concentrations, may be the cause of the increase in carbon stocks, as some theory and models predict.
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.

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.
The useful plants of Tambopata, Peru: I. Statistical hypotheses tests with a new quantitative technique
This paper describes a new, simple, quantitative technique for evaluating the relative usefulness of plants to people. The technique is then compared to the quantitative approaches in ethnobotany…

A decade of satellite-derived rainfall data is analyzed to compare both the 2010 and 2005 drought in Amazonia and predict the impact of the 2010 drought as 2.2 × 1015 grams of carbon, largely longer-term committed emissions from drought-induced tree deaths.
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.
