Through a number of case studies from the West African Sahel, this book links and explores natural resources management from the perspectives of politics, property and production.

Understanding how ecosystems are assembled -- how the species that make up a particular biological community arrive in an area, survive, and interact with other species -- is key to successfully restoring degraded ecosystems. Yet little attention has been paid to the idea of assembly rules in ecological restoration, in both the scientific literature and in on-the-ground restoration efforts. Assembly Rules and Restoration Ecology, edited by Vicky M. Temperton, Richard J. Hobbs, Tim Nuttle, and Stefan Halle, addresses that shortcoming, offering an introduction, overview, and synthesis of the potential role of assembly rules theory in restoration ecology. It brings together information and ideas relating to ecosystem assembly in a restoration context, and includes material from a wide geographic range and a variety of perspectives. Assembly Rules and Restoration Ecology contributes new knowledge and ideas to the subjects of assembly rules and restoration ecology and represents an important summary of the current status of an emerging field. It combines theoretical and practical aspects of restoration, making it a vital compendium of information and ideas for restoration ecologists, professionals, and practitioners.

This two-volume work presents an authoritative world-wide view of our knowledge about, and understanding of, hot-desert ecosystems. This includes some semi-arid and arid areas, as well as deserts in the strict sense. The hot deserts are distinguished from the temperate deserts (which form the subject of another volume in the series) by the virtual absence of snowfall, even though frosts may occur. For each major hot-desert region, expert authors have summarized existing knowledge according to a general outline. This includes descriptions of the ecosystem components (climate, soil, flora and fauna), and discussion of interaction between components and overall ecosystem functioning. The information from the regional chapters has then been integrated into a world-wide view in the ''synthesis'' chapters. Because of its length, the volume is published in two parts. The first volume includes the general synthesis chapters, and regional descriptions of the hot deserts of America and Australia, while the second volume covers the hot deserts of Asia and Africa.

This work is the first to focus systematically on a much-debated topic: the conceptual issues of community ecology, including the nature of evidence in ecology, the role of experiments, attempts to disprove hypotheses, and the value of negative evidence in the discipline. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Built around the concept of linguistic and cultural plurality, this book defines language as an instrument of action and symbolic power. Plurality is conceived here as : a complex array of voices, perspectives and approaches that seeks to preserve the complexity of the multilingual and multicultural enterprise, including language learning and teaching ; a coherent system of relationships among various languages, research traditions and research sites that informs qualitative methods of inquiry into multilingualism and its uses in everyday life ; a view of language as structured sociohistorical object, observable from several simultaneous spatiotemporal standpoints, such as that of daily interactions or that which sustains the symbolic power of institutions. This book is addressed to teacher trainers, young researchers, decision makers, teachers concerned with the role of languages in the evolution of societies and educational systems. It aims to elicit discussion by articulating practices, field observations and analyses based on a multidisciplinary conceptual framework.
