Regional vegetation die-off in response to global-change-type drought.
Future drought is projected to occur under warmer temperature conditions as climate change progresses, referred to here as global-change-type drought, yet quantitative assessments of the triggers andExpand

The potential roles of biological soil crusts in dryland hydrologic cycles
Biological soil crusts (BSCs) are the dominant living cover in many drylands of the world. They possess many features that can influence different aspects of local hydrologic cycles, including soilExpand
