Abstract: AimsBiological soil crusts (biocrusts) dominate soil surfaces in drylands, providing services that include soil stabilization and carbon uptake. In this study, we investigated the direct and biocrust-mediated effects of anthropogenic disturbances in two dryland ecosystems.MethodsWe… read more here.

Abstract: Transitions from semiarid grassland to shrubland states are among the most widely recognized examples of regime shifts in terrestrial ecosystems. Nonetheless, the processes causing grassland–shrubland transitions and their consequences are incompletely understood. We challenge several… read more here.
