Floodplain forests have low resilience to repeated exposure to wildfires. As climate change increases the instances of fires, forests may transform to less productive grassland ecosystems.

Upwind Forest Buffers Rondonia Cropland Against Regional Drought
During severe Amazonia droughts when oceanic supply of moisture failed, the magnitude of rainfall reduction over Rondonia was moderated by enhanced moisture supply from upwind forests.
Trans-Atlantic Dusts May Not Enrich Amazon as Much as Thought
New research indicates that nutrient loads delivered to South American ecosystems by dust originating in Africa are far lower than suggested in previous studies.
How Forest Degradation Affects Carbon and Water Cycles
Forest degradation may be as widespread as deforestation in the Amazon, but its impact on energy, carbon, and water fluxes is less well understood.
Los Incendios del Amazonas Contribuyen al Derretimiento de los Glaciares Andinos
Investigaciones recientes revelan que las emisiones de carbono negro producidas por los incendios en el Amazonas causan que los glaciares en los Andes absorban más radiación solar y se derritan más.
Amazon Fires Contribute to Andean Glacier Melting
New research finds that black carbon emissions produced by fires in the Amazon cause glaciers in the Andes to absorb more sunlight and melt more.
Deforestation Could Exacerbate Drought in the Amazon
Researchers use high-resolution satellite images to parse the effects of land use changes on the energy balance between the rain forest and the atmosphere.
A Simplified Model of Water Vapor Exchange in the Amazon
Evapotranspiration is the exchange of water vapor between land and the atmosphere, and it is hard to measure and model. A new study shows promise for its estimation over large, vegetated landscapes.
Seasonal Leaf Production Is Key Control on Amazon Carbon Balance
Characterizing leaf phenology in process-based models reconciles both “dry season green-up” and drought controls on Amazonian carbon balance.
Ocean Wind Satellites Observe an Amazonian Drought
Satellites designed to observe ocean winds can also be used to map both forest structure and water content, allowing researchers to disentangle factors of carbon loss due to drought in the Amazon.
