Groundwater: A Hidden Influence on River Shape
A new study shows how groundwater influences river dynamics and channel pattern.
Soil Crusts Play a Dual Role in Desertification
Rain falling on bare soil can form a hard crust that prevents further infiltration. But do these crusts worsen land degradation or help to prevent it?
Satellites Track Chlorophyll Fluorescence to Monitor Drought
New satellite observations show connection between solar-induced chlorophyll fluorescence and soil moisture—a key mechanism behind drought onset.
Climate Variability Across Scales Affects Ecosystems over Time
Given enough time, short-term variations in temperature, precipitation, and solar radiation influence the fluxes of water and carbon through ecosystems.
A Model to Predict When a Cholera Outbreak Might Hit the Congo
Researchers determined the environmental conditions most likely to trigger a cholera epidemic in a region in eastern Congo.
