Produktbeschreibung

Sand dune dynamics plays a key role in many arid deserts. This volume provides a synthesis of a specific sand dune ecosystem, the Nizzana site in the Negev Desert. Describing its climate and geophysical/geochemical properties of soils, geological history, flora and fauna, and past/present land-use patterns, it elucidates ecological and geomorphological processes and their interrelations, based on long-term monitoring, in situ experiments and satellite imagery. Particular attention is drawn to the impact of the topsoil biological crust in controlling water availability at local/regional scales. The interdisciplinary approach adopted in this case study offers a good example of a highly complex and dynamic system, which could easily be applied to other sandy ecosystems.

This is a valuable source of information for soil ecologists and microbiologists, conservation biologists, desert ecologists and geographers, geomorphologists, soil scientists and climatologists, lecturers, policy makers and others interested in deserts and desertification.

Rezensionen

From the reviews:

"The book ... offers a comprehensive view of the dune system of the Nizzana area situated in the eastern margins of the Sinai Desert (Israel). The Nizzanna Research site is a long-term research facility that has accumulated interdisciplinary knowledge through time. ... If you are scientifically, academically or professionally interested in desert dune systems or if you have the intellectual curiosity in the complex and fascinating world of dunes, this is a book you should not miss." (José Luis Rubio, ESSC Newsletter, Issue 3, 2009)
