Book Description
This volume was first published in 1981. The history of man's use of arid lands is a sad record of deterioration of the natural resource base and of low and declining living standards for the 300 million people who live in them. One prerequisite to meeting the challenge of reversing the deterioration and of raising living standards is a sound knowledge of the natural ecosystems.

Book Description
In arid lands, where vegetation is sparse or absent, the open ground is not bare but generally covered by a community of small, highly specialized organisms. Cyanobacteria, algae, microfungi, lichens, and bryophytes aggregate soil particles to form a coherent skin - the biological soil crust. It stabilizes and protects the soil surface from erosion by wind and water, influences water runoff and infiltration, and contributes nitrogen and carbon to desert soils. Soil surface disturbance, such as heavy livestock grazing, human trampling or off-road vehicles, breaks up the fragile soil crust, thus compromising its stability, structure, and productivity. This book is the first synthesis of the biology of soil crusts and their importance as an ecosystem component. Composition and functioning of different soil-crust types are discussed, and case studies are used to show the impact of crusts on landscape hydrology, soil stability, nutrient cycles, and land management.

Book Description
The Biology and Utilization of Shrubs brings together the wide range of information about shrubs from many disciplines and world locations. The book is organized into seven parts. Part I describes the major shrublands found on each of the vegetated continents. It provides an overview of the dominant shrubland types as well as the associated features of soil and climate that influence the geographic distribution of major shrub species. Part II discusses environmental influences and plant responses. Part III considers the range of genetic diversity for important traits and how these may vary in different habitats. Part IV discusses the effects of stress on physiological processes of shrubs, and the kinds of strategies shrubs employ to meet physiological stress. Part V offers evidence to support the claim that the many virtues of shrubs provide a basis for sustaining shrub use for livestock fodder, wildlife habitat, reclamation and erosion control, fuel, and naturalized landscaping. Part VI outlines methods for collecting and processing seeds from natural stands or from superior genotypes planted in seed production orchards. Part VII describes cultural adaptation to shrub use in a livestock-dominated primitive culture, followed by a detailed economic analysis of establishing shrub plantations to improve livestock production.

Book Description
"Provides interesting and thought-provoking reading and is highly recommended to anyone interested in desert ecosystems or community ecology. The book . . . should serve as an inspiration to many for future research."—Journal of Biogeography "This book is not just about deserts; it is an update of the contributions that research in desert systems is making to community ecology. . . This book will provide a useful reference for desert ecologists, as well as indicate critical directions where progress needs to be made."—Ecology "This important book fills a significant gap in previous syntheses by presenting a detailed series of reviews of current understanding of community patterns and structure in desert environments. . . . Each chapter is thorough and well written and . . . closes with a discussion of suggested future research. . . . [T]hese ideas will do much to focus interest on the importance of desert systems in understanding community. Thus, this book has interest well beyond desert ecologists alone."—BioScience "Valuable reading and reference for ecology students, teachers and researchers."—Quarterly Review of Biology
