The book "Arid Dune Ecosystems" offers a comprehensive analysis of the Nizzana site in the Negev desert area, highlighting the dynamics of sand dunes in arid ecosystems. It addresses the climatic conditions as well as the geophysical and geochemical properties of the soil, providing insights into the geological history, flora and fauna, and land use in both the past and present. By combining long-term monitoring, field experiments, and satellite imagery, it details the interaction between ecological and geomorphological processes. Special attention is given to the role of the biological soil crust, which influences water availability at both local and regional levels. This interdisciplinary work is a valuable contribution to understanding complex and dynamic systems in desert ecosystems and offers inspiration for similar studies in other sandy habitats.
