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 ...

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 ...

Theoretical models predict nurse plant facilitation enhances species richness by ameliorating stressful environmental conditions and expanding distributional ranges of stress-intolerant species into harsh environments. ...

The White-fronted Woodpecker (Melanerpes cactorum) drills wells in living branches and trunks of trees and shrubs to feed on sap flows, providing an energy-rich food resource for other bird species diverse in ecological ...

The urine field osmolality in Zonotrichia capensis along a latitudinal gradient in rainfall and temperature in Chile was examined. We also investigated latitudinal variation in the renal traits that mediate how these birds ...
