Ecology of Desert Systems

Front Cover
Elsevier, Mar 25, 2002 - Science - 343 pages
Conventional wisdom considers deserts stark, harsh regions that support few living things. Most people also believe that water alone makes the desert bloom. Ecology of Desert Systems challenges these conventional views.

This volume explores a broad range of topics of interest to ecosystem, population, community, and physiological ecologists. Climate, weather patterns, geomorphology, and wind and water processes are examined as variables that affect the distribution of biota through fundamental ecosystem processes. Descriptions of morphological, behavioral, and physiological adaptations of desert biota illuminate, through the lens of patch dynamics, principles for understanding observed patterns of primary production, nutrient cycling, and the effects of consumers. Desertification, and the techniques for monitoring and quantifying it, is examined within the framework of desert ecosystem patterns and processes.



* Focuses on the interactions of climate, soil, and biota along a spectrum of spatial and temporal scales
* Details the role of animals in desert ecosystems and landscape processes
* Examines watershed scale processes, the ecology of ephemeral lakes, and the ecological changes identified with desertification
* Outlines the fundamental concepts relevant to sustainable development of arid lands

the ecosystem is an organism where if there is one animal its one and if there is more then one animal then its called a population and if there is more then five then its called a community.
so
this book is about what the ecosystem is and the definition for it.

About the author (2002)

Professor Walter G. Whitford received his PhD from the University of Rhode Island in Physiolgical-Ecology. He spent the next fifty years working in the Chihuahuan Desert as a faculty member in Biology at New Mexico State University (NMSU) where he was principal investigator in the Desert Biome Program which was part of the International Biological Program. His research focused on field experiments and studies of termites and seed harvesting ants. That program stimulated his commitment to the importance of soil in arid ecosystems and the organisms that are involved in nutrient cycling. He also served as the first principal investigator for the Jornada Long Term Ecological Research Program. As principal investigator, he published more than 150 papers in peer reviewed journals dealing with most aspects of desert ecology. In 1993, he left the university to work as a senior research ecologist with the U. S. Environmental Protection Agency with a focus on monitoring and assessing the health of arid ecosystems. After retiring from the EPA he produced the first edition of Ecology of Desert Systems and continued to teach and do research in the Chihuahuan Desert. While a professor, he did research in Israel and Australia, evaluated arid lands research programs in South Africa, and organized a symposium on the Atacama and long-term ecological research in Chile. Before embarking on the 2nd edition of Ecology of Desert Systems, he was author or co-author of more than 300 peer-reviewed publications.
