Direct evidence that drought-weakened Amazonian forests 'inhale less carbon'
For the first time, an international research team has provided direct evidence of the rate at which individual trees in the Amazonian basin 'inhale' carbon from the atmosphere during a severe drought. They ...

Sediment supply drives floodplain evolution in Amazon Basin
A new study of the Amazon River basin shows lowland rivers that carry large volumes of sediment meander more across floodplains and create more oxbow lakes than rivers that carry less sediment.
Drought, fires impact ability of Amazon to hold carbon dioxide
Fires in the Amazon could jeopardize the forest's ability to soak up carbon dioxide emissions even as deforestation there slows down, according to a Penn State geographer.
