Amazon forests green-up during 2005 drought.
Coupled climate-carbon cycle models suggest that Amazon forests are vulnerable to both long- and short-term droughts, but satellite observations showed a large-scale photosynthetic green-up in intact evergreen forests of the Amazon in response to a short, intense drought in 2005. These findings suggest that Amazon forests, although threatened by human-caused deforestation and fire and possibly ...
متن کاملAmazon forests did not green‐up during the 2005 drought
[1] The sensitivity of Amazon rainforests to dry‐season droughts is still poorly understood, with reports of enhanced tree mortality and forest fires on one hand, and excessive forest greening on the other. Here, we report that the previous results of large‐scale greening of the Amazon, obtained from an earlier version of satellite‐ derived vegetation greenness data ‐ Collection 4 (C4) Enhanced...

متن کاملEvaluating multiple causes of persistent low microwave backscatter from Amazon forests after the 2005 drought
Amazonia has experienced large-scale regional droughts that affect forest productivity and biomass stocks. Space-borne remote sensing provides basin-wide data on impacts of meteorological anomalies, an important complement to relatively limited ground observations across the Amazon's vast and remote humid tropical forests. Morning overpass QuikScat Ku-band microwave backscatter from the forest ...
متن کاملGreen Leaf Volatile Emissions during High Temperature and Drought Stress in a Central Amazon Rainforest.
Prolonged drought stress combined with high leaf temperatures can induce programmed leaf senescence involving lipid peroxidation, and the loss of net carbon assimilation during early stages of tree mortality. Periodic droughts are known to induce widespread tree mortality in the Amazon rainforest, but little is known about the role of lipid peroxidation during drought-induced leaf senescence. I...
