The term ‘systems theory’ is used to characterize a set of disparate yet related approaches to fields as varied as information theory, cybernetics, biology, sociology, history, literature, and philosophy. What unites each of these traditions of systems theory is a shared focus on general features of systems and their fundamental importance for diverse areas of life. Yet there are considerable differences among these traditions, and each tradition has developed its own methodologies, journals, and forms of anaylsis. This book explores this terrain and provides an overview of and guide to the traditions of systems theory in their considerable variety. The book draws attention to the traditions of systems theory in their historical development, especially as related to the humanities and social sciences, and shows how from these traditions various contemporary developments have ensued. It provides a guide for strains of thought that are key to understanding 20th century intellectual life in many areas.

Critics of the ecosystem concept have noted the tendency of ecosystem-based studies to overemphasize energy flow, to rely on functionalist assumptions, to neglect historical and evolutionary factors, and to overlook the role of individuals as the locus of natural selection and decision making. In this volume, leading figures in the study of biological and human ecology evaluate these criticisms and propose ways to advance the state of knowledge in ecological research.

'The scope and clarity of this book make it accessible and informative to a wide readership. Its messages should be an essential component of the education for all students from secondary school to university... [It] provides a clear and comprehensible account of concepts that can be applied in our individual and collective lives to pursue the promising and secure future to which we all aspire' From the Foreword by Maurice Strong, Chairman of the Earth Council and former Secretary General of the United Nations Conference on Environment and Development (Earth Summit) The most important questions of the future will turn on the relationship between human societies and the natural ecosystems on which we all, in the end, depend. The interactions and interdependencies of the social and natural worlds are the focus of growing attention from a wide range of environmental, social and life sciences. Understanding them is critical to achieving the balance involved in sustainable development. Human Ecology: Basic Concepts for Sustainable Development presents an extremely clear and accessible account of this complex range of issues and of the concepts and tools required to understand and tackle them. Extensively supported by graphics and detailed examples, this book makes an excellent introduction for students at all levels, and for general readers wanting to know why and how to respond to the dilemmas we face.

Students of nature around the world revere Eugene Odum as a founder and pioneer of ecosystem ecology. In this biography of Odum, Betty Jean Craige depicts the intellectual growth, creativity, and vision of the scientist who made the ecosystem concept central to his discipline and translated the principles of ecosystem ecology into lessons in preserving the natural environment. Placing Odum's achievements in historical context, Craige traces his life from his childhood through his education, his collaboration with his brother Howard T. Odum in developing methods to study ecosystems, his contributions to the field of radiation ecology, his emergence as an internationally distinguished educator of ecosystem ecology, and his environmental activism. Craige also describes Odum's role in the creation of the Savannah River Ecology Laboratory, the Marine Institute on Sapelo Island, and the Institute of Ecology at the University of Georgia, where he became identified with the statement "The ecosystem is greater than the sum of its parts." Odum's textbook Fundamentals of Ecology is a classic, published in numerous editions and translations worldwide. Odum achieved membership in the National Academy of Sciences, shared with his brother the prestigious Crafoord Prize for Ecology, accepted six honorary doctorates, and received numerous awards for environmental activities.

Adopting the novel approach of viewing the role of fungi from the perspective of ecosystem functions, this book examines the importance of fungi in soil formation, plant primary production, sustenance of secondary producers, and regulation of plant and animal populations and communities. This volume emphasizes the idea that fungi are not alone in the regulation of these processes. It addresses the main processes occurring in ecosystems and showing where and how fungi are critical, and enables readers to gain a better understanding of the role of fungi in shaping ecosystems. "Fungi in Ecosystem Processes" considers the negative impact of fungi on faunal productivity and includes more than 1200 citations.

Earth Days details the events of the revolution in ecology initiated by the publication of Silent Spring from the perspective of someone involved in its events. It is a book having to do with ideas and the people who held them. Earth Days starts with Rachel Carson and the other writers and scientists whose words caught the attention of the public on Earth Day. It tells about the Odum brothers from the corn pone South, champions of the ecosystem idea, Robert MacArthur, the "James Dean" of ecology, and Jared Diamond, who tried to be his successor and in the effort set off a war in ecology. It tells about Dan Simberloff, who rebelled against the science inspired by his own mentors in that war. It tells about Paul Ehrlich and David Pimentel, for whom no environmental issue was beyond their expertise. It also tells about Gene Likens, who looked and acted more like an insurance salesman, yet found a way through the swirling controversies in his science to put it to good practical use. There are, of course, many others, each trying to find their own personal way in the broad, important science that is ecology. Earth Days details that revolution from the perspective of someone involved in its events. It also gives the reader the necessary background to follow the most technical material. Difficult material becomes easy, lively reading. -Howard V. Cornell (University of Delaware): "Fantastic! It kept me up all night. I couldn't put it down." -Nicholas Gotelli (University of Vermont): "It is very lively and fun to read." -Daniel Simberloff (University of Tennessee): " an excellent and engaging writer appears to be a really major and interesting book." -David Pimentel (Cornell University): " fantastic job of writing to capture the views of numerous ecologists!" -Gene Likens (New York Botanical Garden): "I learned some things about myself."

Ecotoxicology is a relatively new scientific discipline. Indeed, it might be argued that it is only during the last 5-10 years that it has come to merit being regarded as a true science, rather than a collection of procedures for protecting the environment through management and monitoring of pollutant discharges into the environment. The term 'ecotoxicology' was first coined in the late sixties by Prof. Truhaut, a toxicologist who had the vision to recognize the importance of investigating the fate and effects of chemicals in ecosystems. At that time, ecotoxicology was considered a sub-discipline of medical toxicology. Subsequently, several attempts have been made to portray ecotoxicology in a more realistic light. Notably, both Moriarty (1988) and F. Ramade (1987) emphasized in their books the broad basis of ecotoxicology, encompassing chemical and radiation effects on all components of ecosystems. In doing so, they and others have shifted concern from direct chemical toxicity to humans, to the far more subtle effects that pollutant chemicals exert on natural biota. Such effects potentially threaten the existence of all life on earth. Although I have identified the sixties as the era when ecotoxicology was first conceived as a coherent subject area, it is important to acknowledge that studies that would now be regarded as ecotoxicological are much older.

The first practical yet in-depth exploration of how to reclaim the post-industrial landscape, this volume includes excellent case studies by practitioners and policy makers from around the US, giving first rate practical examples. The book addresses new thinking about landscape, which applies new techniques to the task of transforming outdated and disused post-extraction landscapes through design. In the USA alone, there are nearly 500,000 abandoned mines in need of reclamation and this book provides the first in-depth guidance on this real and pressing issue. Drawing on the work of the well-known Project for Reclamation Excellence at Harvard's Graduate School of Design, this volume outlines the latest design thinking, theory and practice for landscape planners, landscape architects and designers and others interested in maximizing the future potential of reclaimed land.

Arctic Adaptations

The common view of indigenous Arctic cultures, even among scholarly observers, has long been one of communities continually in ecological harmony with their natural environment. In Arctic Adaptations, Igor Krupnik dismisses the textbook notion of traditional societies as static. Using information from years of field research, interviews with native Siberians, and archaeological site visits, Krupnik demonstrates that these societies are characterized not by stability but by dynamism and significant evolutionary breaks. Their apparent state of ecological harmony is, in fact, a conscious survival strategy resulting from "a prolonged and therefore successful process of human adaptation in one of the most extreme inhabited environments in the world." As their physical and cultural environment has changed--fluctuating reindeer and caribou herds, unpredictable weather patterns, introduction of firearms and better seacraft--Arctic communities have adapted by developing distinctive subsistence practices, social structures, and ethics regarding utilization of natural resources. Krupnik's pioneering work represents a dynamic marriage of ethnography and ecology, and makes accessible to Western scholars crucial findings and archival data previously unavailable because of political and language barriers.
