Extreme Lithium Isotope Fractionations During Intense Weathering
Extreme lithium fractionation is observed when primary minerals in andesite are transformed to secondary clay minerals and then to oxides with intensive chemical weathering in a tropical climate.

Biological Crusts Affected by Drought Can Still Stabilize Soils
Results of in situ experiments on natural microbial communities suggest that biological crusts can protect soils from erosion, but their protective role could be compromised under predicted future climate scenarios.
