The last decade was marked by efforts to define and identify the main cyanobacterial players in biological crusts around the world. However, not much is known about biocrusts in Brazil’s tropical savanna (cerrado), despite ...

Biological soil crusts or biocrusts have critical ecological roles in dryland ecosystems including soil stabilization, erosion control and nutrient cycling. Global environmental changes are expected to impact terrestrial ...

Grazing is directly related to land degradation and desertification in global drylands. Grazing impacts on vascular plants, reasonably well-known, depend on its intensity and are modulated by local aridity conditions. ...

Biocrusts presented their highest expression in the inter-patches. However, an increase in the level of aridity along the landscape could lead to vascular plants to make a notable influence on the spatial distribution of ...

Biological soil crusts (biocrusts) play a fundamental role in arid and semiarid areas of South America. Nevertheless, little attention has been paid to the distribution and coverage of them, and studies about biocrusts are ...

Cyanobacteria typically colonize the surface of arid soils, building biological soil crust (biocrusts) that provide a variety of ecosystem benefits, ranging from fertilization to stabilization against erosion. We investigated ...

Crostas biológicas (CBs) consistem em uma comunidade de elementos entrelaçados composta por organismos poiquiloídricos, como cianobactérias, algas verdes, microfungos, bactérias, líquens, musgos e microartrópodes. Estas ...

In arid areas, biological activity responds to precipitation pulses, with different activation thresholds for different organisms. Biocrusts, communities of cyanobacteria, green algae, lichens and mosses living in the soil ...
