Ecology is an historical science in which theories can be as difficult to test as they are to devise. This volume, intended for ecologists and evolutionary biologists, reviews ecological theories, and how they are generated, evaluated, and categorized. Synthesizing a vast and sometimes labyrinthine literature, this book is a useful entry into the scientific philosophy of ecology and natural history. The need for integration of the contributions to theory made by different disciplines is a central theme of this book. The authors demonstrate that only through such integration will advances in ecological theory be possible. Ecologists, evolutionary biologists, and other serious students of natural history will want this book.

This widely anticipated revision of the groundbreaking book, Ecological Understanding, updates this crucial sourcebook of contemporary philosophical insights for practicing ecologists and graduate students in ecology and environmental studies. The second edition contains new ecological examples, an expanded array of conceptual diagrams and illustrations, new text boxes summarizing important points or defining key terms, and new reference to philosophical issues and controversies. Although the first edition was recognized for its clarity, this revision takes the opportunity to make the exposition of complex topics still clearer to readers without a philosophical background.Readers will gain an understanding of the goals of science, the structure of theory, the kinds of theory relevant to ecology, the way that theory changes, what constitutes objectivity in contemporary science, and the role of paradigms and frameworks for synthesis within ecology and in integration with other disciplines. Finally, how theory can inform and anchor the public use of ecological knowledge in civic debates is laid out. This new edition refines the understanding of how the structure and change of theory can improve the growth and application of one of the 21st century''s key sciences.- Explains the philosophical basis of ecology in plain English- Contains chapter overviews and summaries- Text boxes highlight key points, examples, or controversies- Diagrams explain structure and development of theory, and integration- Evaluates and relates paradgims in ecology- Illustrates philosophical issues with classic and new ecological research

The study of ecosystems, fundamental to ecology, has been complemented by the growing field of landscape ecology. Ecosystem Function in Heterogeneous Landscapes addresses how interactions among ecosystems affect the functioning of individual ecosystems and the larger landscape. This groundbreaking synthesis unites ecosystem ecology's knowledge of system function with landscape ecology's knowledge of spatial structure. Practical concerns about scaling up from individual ecosystems to larger landscapes require an understanding of how networks of interacting ecosystems function together. The book elucidates the challenges faced by ecosystem scientists working in spatially heterogeneous systems, relevant conceptual approaches used in other disciplines and in different ecosystem types, and the importance of spatial heterogeneity in conservation resource management. The distinguished authors discuss how how much heterogeneity needs to be taken into account for specific types of scientific and management issues.Their chapters cover the spectrum from proposing novel conceptual approaches to detailing the practical implications of heterogeneous landscapes for fire management, water management and conservation planning.

Among the most dif?cult problems in the life sciences is the challenge to understand the details of how ecosystems/watersheds/landscapes function. Yet,the welfare of all life,not just the human species,depends upon the s- cessful functioning of diverse and complicated ecosystems, each with va- ous dimensions and compositions. Central to this “working” is the dominance, and to a major extent control, of ecosystems by organisms, which means that these systems are constantly changing as the component organisms change and evolve. Such changes increase the challenge to understand the functioning of ecosystems and landscapes. Moreover,und- standing the interactions among the myriad components of these systems is mind-boggling as there are scores of biotic (probably many thousands of species when the microbial components are fully enumerated through genomics) and countless abiotic (ions, molecules, and compounds) entities, all simultaneously interacting and responding to diverse external factors to produce functional or dysfunctional environments for life. This book focuses on the problems of connectedness and ecosystem fu- tioning. It is dif?cult enough to understand how an ecosystem functions when it is considered in isolation, but all ecosystems are open and c- nected to everything else. Clearly, the inputs to any ecosystem are the o- puts from others and vice versa, and as such the ?uxes represent major, if not critical, points for managing or changing the overall functioning of an ecosystem or landscape. A major challenge is to ?nd appropriate conceptual frameworks to address these complicated problems.

This volume focuses on the integration of population and ecosystem ecology - an approach that offers vast potential for improving our understanding of the complexities of nature and the management of environmental problems. The editors have brought together a group of experts to explore diverse aspects of linking species and ecosystem perspectives - theoretical, empirical and pragmatic. These include: processes that range from a local to a planetary scale; the role of organisms as ecosystem engineers; the use of ecological flow chains to link population and ecosystem processes; numerous examples of the influence of species on ecosystem processes and vice versa; a unique blend of problems and processes drawn from marine; freshwater and terrestrial ecosystems; problems of "species redundancy" in ecosystem processes; stoichiometric constraints on species interactions; and scaling and aggregation problems. "Linking Species and Ecosystems" establishes conceptual frameworks for the rigorous study of interactions between species and ecosystems, it points to still-unanswered questions, and it identifies future research directions.Integration of ecology with its implications for teaching, research and society are central to the book. This volume should serve as a resource for ecology researchers, students, and environmental managers and should stimulate debate on the future integration of the field. This book should be of interest to ecologists - graduate students and established researchers; biology; zoology; ecology; evolutionary biology; integrative or organismal biology; entomology; plant science; forestry; wildlife management; and environmental studies.

Novel Aspects of Insect-Plant Interactions Edited by Pedro Barbosa and Deborah K. Letourneau Focusing on three trophic levels, this study widens the current understanding of the ecological interactions between plants, herbivores, and their parasitoids and predators. Emphasized are the mediating effects of plant-derived allelochemicals on those interactions. The book also covers microorganisms as mediators of intertrophic and intratrophic interactions; theory and mechanisms: plant effects via allelochemicals on the third trophic level; and key roles of plant allelochemicals in survival strategies of herbivores. 1988 (0 471-83276-6) 362 pp. Plant-Animal Interactions Evolutionary Ecology in Tropical and Temperate Regions Edited by Peter W. Price, Thomas M. Lewinsohn, G. Wilson Fernandes and Woodruff W. Benson An outgrowth of an international symposium on Evolutionary Ecology of Tropical Herbivores held at UNICAMP, Brazil, this unique collaborative effort from leading scientists worldwide is the first comparative analysis of the existing ecological systems of temperate and tropical regions. In-depth and timely, the book's manifold analyses includes a discussion of tropical and temperate comparisons; mutualistic relationships between plants and animals; antagonistic relationships between plants and animals; plant-butterfly interactions; specificity in plant utilization; and community patterns in natural and agricultural systems. Amply illustrated with 150 detailed graphics, the book provides a fascinating visual tour of the flora and fauna described. 1991 (0 471-50937-X) 639 pp. Integrated Pest Management Systems and Cotton Production Edited by Raymond E. Frisbie, Kamal M. El-Zik and L. Ted Wilson This work sheds light on the link between the thriving U.S. cotton crop and integrated pest management. It offers a unique theoretical and conceptual framework for studying the cotton-IPM system. Other relevant issues such as the development and use of pest models, quantitative sampling principles in cotton IPM, economic injury levels and thresholds for cotton pests, and strategies and tactics for managing weeds, plant pathogens, nematodes, and insects are also described. Covering every facet of IPM technology, this is a significant contribution to the literature of pest management. 1989 (0 471-81782-1) 437 pp.

I was asked to introduce this volume by examining "why a knowledge of ecosys­ tem functioning can contribute to understanding species activities, dynamics, and assemblages." On the one hand, the answer is very simple and general: because all species live in ecosystems, they are part of and dependent on ecosystem processes.
