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

EXOTIC PLANT INVASION ALTERS NITROGEN DYNAMICS IN AN ARID GRASSLAND
The introduction of nonnative plant species may decrease ecosystem stability by altering the availability of nitrogen (N) for plant growth. Invasive species can impact N availability by changingExpand

The world at your feet: desert biological soil crusts
Desert soil surfaces are generally covered with biological soil crusts, composed of a group of organisms dominated by cyanobacteria, lichens, and mosses. Despite their unassuming appearance, theseExpand

MICROENVIRONMENTS AND MICROSCALE PRODUCTIVITY OF CYANOBACTERIAL DESERT CRUSTS 1
We used microsensors to characterize physicochemical microenvironments and photosynthesis occurring immediately after water saturation in two desert soil crusts from southeastern Utah, which wereExpand

Disturbance and Recovery of Biological Soil Crusts
Disturbance can profoundly affect the cover, species composition, and the physiological functioning of biological soil crusts. The disturbances we discuss include air pollution; exposure to oil,Expand

Biological Soil Crusts: Characteristics and Distribution
Biological soil crusts result from an intimate association between soil particles and cyanobacteria, algae, microfungi, lichens, and bryophytes (in different proportions) which live within, orExpand

Carbon and Nitrogen Fixation Differ between Successional Stages of Biological Soil Crusts in the Colorado Plateau and Chihuahuan Desert
Abstract Biological soil crusts (cyanobacteria, mosses and lichens collectively) perform essential ecosystem services, including carbon (C) and nitrogen (N) fixation. Climate and land-use change areExpand
