Drought effects on litterfall, wood production and belowground carbon cycling in an Amazon forest: results of a throughfall reduction experiment

Drought effects on litterfall, wood production and belowground carbon cycling in an Amazon forest: results of a throughfall reduction experiment

The Amazon Basin experiences severe droughts that may become more common in the future. Little is known of the effects of such droughts on Amazon forest productivity and carbon allocation. We tested the prediction that severe drought decreases litterfall and wood...

The opportunity costs of reducing carbon emissions in an Amazonian agroindustrial region: the Xingu River headwaters

Negotiations are proceeding for a new international climate change regime that will compensate tropical nations that reduce their carbon emissions from deforestation and forest degradation. In anticipation of this new mechanism designed to slow deforestation,...

Interactions among Amazon land use, forests and climate: prospects for a near-term forest tipping point

Some model experiments predict a large-scale substitution of Amazon forest by savannah-like vegetation by the end of the twenty-first century. Expanding global demands for biofuels and grains, positive feedbacks in the Amazon forest fire regime and drought may...

Modeling the effects of throughfall reduction on soil water content in a Brazilian Oxisol under a moist tropical forest

Access to water reserves in deep soil during drought periods determines whether ornot the tropical moist forests of Amazonia will be buffered from the deleterious effectsof water deficits. Changing climatic conditions are predicted to increase periods of droughtin...
