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.
This comprehensive account of arid-land ecosystems will be of importance to university teachers and professional ecologists throughout the world.
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. It is to this end that the IBP and other relevant studies, reported in this and a succeeding volume, are addressed. The subject matter of the two volumes is organised into five major topics; two are dealt with in the first volume. The first section of volume one describes the structure of arid ecosystems in terms of climate, soils, geomorphology, hydrology, flora and fauna. All continents except South America are covered. In the second section the processes which operate within, and control, the ecosystem are dealt with individually. This comprehensive account will be of importance to university teachers and professional ecologists throughout the world.
First published in 1995. This title presents the proceedings of The Second International Conference on Range Management in the Arabian Gulf, 1990. The objectives of the Conference were to: evaluate progress made following the First Conference; exchange information on range management development; review advances in applicable technologies; discuss potential strategies for range enhancement and assemble pertinent recommendations for enactment. As such, these proceedings will serve as a reference base for researchers, professors, lecturers, and students alike, both at advanced undergraduate and graduate levels.
Over the last twenty years there has been a major expansion of knowledge in the field of landforms and landforming processes of deserts. This advanced-level book provides a benchmark for the current state of science, and is written by an international team of authors who are acknowledged experts in their fields.
The Soviet invasion of Afghanistan in 1979 stunned the world and ushered in a new period of superpower confrontation. Research into Afghan society was severely curtailed, and the ability to research the Afghan resistance was non-existent. This book, first published in 1988, was the result of a Swedish seminar that focused on the results of the war on the people and culture of Afghanistan.
In eastern Australia, grassy eucalypt woodlands have been under severe pressure from agricultural development, with problems of land degradation and species decline being most severe in the cropping lands of south-eastern Australia. Managing and Conserving Grassy Woodlands describes a set of principles that will enable landholders to maintain or increase productivity without compromising ecological sustainability, and at the same time maintaining a substantial proportion of the native flora and fauna. The book provides the technical foundations underpinning the principles and explains the importance of planning at a landscape scale. Each major principle is addressed in a separate chapter which explains the scientific understanding behind the principle and which discusses some of the issues relating to its practical application. Additional chapters outline the basic ecological concepts underpinning the principles and the responses of landholders who have had the opportunity to discuss and reflect on the principles. For those interested in translating the principles into a property plan, a final chapter explores the steps that can be taken. Managing and Conserving Grassy Woodlands is intended for those at the interface of disciplinary research and on-ground application, whether they are working in research, regional planning, extension, landcare or land management.
"A fascinating historical narrative about the unfolding sequence of large ecosystem research programs over the past 40 years. As a player on this stage, Coleman conveys the intimate personalities and politics while still offering insightful and objective evaluations. Interwoven throughout the story is a remarkably detailed textbook of ecosystem science from then until today."--Paul G. Risser, University of Oklahoma

Succession-nothing in plant, community, or ecosystem ecology has been so elaborated by terminology, so much reviewed, and yet so much the center of controversy. In a general sense, every ecologist uses the concept in teaching and research, but no two ecologists seem to have a unified concept of the details of succession. The word was used by Thoreau to describe, from a naturalist's point of view, the general changes observed during the transition of an old field to a forest. As data accumulated, a lengthy taxonomy of succession developed around early twentieth century ecologists such as Cooper, Clements, and Gleason. Now, nearer the end of the century, and after much discussion concerning the nature of vegetation communities, where do ecologists stand with respect to knowledge of ecological succession? The intent of this book is not to rehash classic philosophies of succession that have emerged through the past several decades of study, but to provide a forum for ecologists to present their current research and present-day interpretation of data. To this end, we brought together a group of scientists currently studying terrestrial plant succession, who represent research experience in a broad spectrum of different ecosystem types. The results of that meeting led to this book, which presents to the reader a unique summary of contemporary research on forest succession.
