Water availability is one of the main limiting factors that control ecosystem functions and productivity in semiarid regions. Vegetation of these regions usually presents a patchy distribution where sparse plant cover is...

The current knowledge of the stratigraphy of Niger benefited greatly from the mining, hydrocarbon, hydrogeological, and paleontological sciences. Exploration by early explorers and studies of the aquifers initially spark...

This excellent history of Peru proposes and proves an entirely new thesis on its nineteenth century: the changes in its economy that might have led to a better future were undone by taxes and other demands at the nationa...

In arid and semiarid areas, the interplant spaces are usually covered by physical and biological soil crusts. These crusts, though representing an almost negligible portion of the soil profile, have a number of crucial r...

This book condenses some of the critical features of the discussion about the interpretative problems of quantum mechanics, pointing out some possible ways out of the conundrum. In order to set the road for these matters...
