A plethora of different theories, models, and concepts make up the field of community ecology. Amid this vast body of work, is it possible to build one general theory of ecological communities? What other scientific areas might serve as a guiding framework? As it turns out, the core focus of community ecology—understanding patterns of diversity and composition of biological variants across space and time—is shared by evolutionary biology and its very coherent conceptual framework, population genetics theory. The Theory of Ecological Communities takes this as a starting point to pull together community ecology's various perspectives into a more unified whole. Mark Vellend builds a theory of ecological communities based on four overarching processes: selection among species, drift, dispersal, and speciation. These are analogues of the four central processes in population genetics theory—selection within species, drift, gene flow, and mutation—and together they subsume almost all of the many dozens of more specific models built to describe the dynamics of communities of interacting species. The result is a theory that allows the effects of many low-level processes, such as competition, facilitation, predation, disturbance, stress, succession, colonization, and local extinction to be understood as the underpinnings of high-level processes with widely applicable consequences for ecological communities. Reframing the numerous existing ideas in community ecology, The Theory of Ecological Communities provides a new way for thinking about biological composition and diversity.

This volume presents an overview of current accomplishments and future directions in ecological theory. The twenty-three chapters cover a broad range of important topics, from the physiology and behavior of individuals or groups of organisms, through population dynamics and community structure, to the ecology of ecosystems and the geochemical cycles of the entire biosphere. The authors focus on ways in which theory, whether expressed mathematically or verbally, can contribute to defining and solving fundamental problems in ecology. A second aim is to highlight areas where dialogue between theorists and empiricists is likely to be especially rewarding. The authors are R. M. Anderson, C. W. Clark, M. L. Cody, J. E. Cohen, P. R. Ehrlich, M. W. Feldman, M. E. Gilpin, L. J. Gross, M. P. Hassell, H. S. Horn, P. Kareiva, M.A.R. Koehl, S. A. Levin, R. M. May, L. D. Mueller, R. V. O'Neill, S. W. Pacala, S. L. Pimm, T. M. Powell, H. R. Pulliam, J. Roughgarden, W. H. Schlesinger, H. H. Shugart, S. M. Stanley, J. H. Steele, D. Tilman, J. Travis, and D. L. Urban. Originally published in 1989. 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.

Despite claims to the contrary, the science of ecology has a long history of building theories. Many ecological theories are mathematical, computational, or statistical, though, and rarely have attempts been made to organize or extrapolate these models into broader theories. The Theory of Ecology brings together some of the most respected and creative theoretical ecologists of this era to advance a comprehensive, conceptual articulation of ecological theories. The contributors cover a wide range of topics, from ecological niche theory to population dynamic theory to island biogeography theory. Collectively, the chapters ably demonstrate how theory in ecology accounts for observations about the natural world and how models provide predictive understandings. It organizes these models into constitutive domains that highlight the strengths and weaknesses of ecological understanding. This book is a milestone in ecological theory and is certain to motivate future empirical and theoretical work in one of the most exciting and active domains of the life sciences.

"Chapter 1 establishes the context of such a search for pattern, presenting essential definitions and exploring early work on community structure and organization. The various biotic and abiotic factors which may influence communities and their dynamics are reviewed in Chapter 2, while the way in which the interrelationships between organisms are structured within the community in food webs or in the partitioning of available resources are considered in separate chapters on food webs, niche relationships and species guilds. Later chapters explore the factors determining the assembly of communities, species composition and pattern of relative abundance and the relative roles of deterministic and stochastic processes in determining community structure. The concluding section explores the implications of observed patterns of structure and organization for stability. The mathematical analyses which are an essential component of this topic are included only where essential for understanding and are presented in special box features. Each mathematical section has been carefully structured and fully explained in biological terms. Community Ecology presents a refreshingly readable course text for advanced undergraduates in ecology."--BOOK JACKET.

Pardeck demonstrates that the ecological approach to social work practice stresses effective intervention, and that effective intervention occurs through not only working with individuals, but also with the familial, social, and cultural factors that impact their social functioning. The power of the ecological approach, through focusing on multiple factors for assessment and intervention, is that it integrates empirically based theories from various fields including social work, psychology, sociology, and anthropology. Pardeck provides an orientation to the role of social work practitioners within the human services. He differentiates the unique contributions of social work and explains them in terms of the needs and goals of an ecological approach to practice. An ecological approach to practice stresses that effective social work intervention occurs through not only working with individuals, but also with the familial, social, and cultural factors that impact their social functioning. The power of the ecological approach, through focusing on multiple factors for assessment and intervention, is that it integrates empirically based theories from various fields including social work, psychology, and anthropology. The book represents an effort to define the goals, commitments, and approaches that have emerged out of the history of social work and to relate them to similar concepts and values that are central to an ecological approach to practice. Three pervasive and unifying themes run through the book. One is the constant commitment to goals of facilitating human development. Pardeck suggests this is a central ethic that defines and distinguishes an ecological approach to social work practice. The second theme is an affirmation of the basic utility of a systems approach in conceptualizing and intervening in human needs, concerns, and problems. The ecological perspective views human beings as social organisms engaged in patterns of relationships that nurture or inhibit this basic humanity. The third theme is an interactionist view of the importance of person-environment fit as a central dynamic in human functioning. The traditional intra-psychic aspects of human behavior have tended to obscure the immense importance of both nurturing and potentially damaging forces at work in the social environment. This volume will be of considerable interest to social work educators and practitioners as well as their research libraries.

Community ecology is the study of the interactions between populations of co-existing species. This book provides a survey of the state-of-the-art in theory and applications of community ecology, with special attention to topology, dynamics, the importance of spatial and temporal scale, as well as applications to emerging problems in human-dominated ecosystems (including the restoration and reconstruction of viable communities). It adopts a mainly theoretical approach and focuses on the use of network-based theory which remains little explored in standard community ecology textbooks. The book includes discussion of the effects of biotic invasions on natural communities, the linking of ecological network structure to empirically measured community properties and dynamics, the effects of evolution on community patterns and processes, and the integration of fundamental interactions into ecological networks. A final chapter indicates future research directions for the discipline. This book provides ideal graduate seminar course material.

Why do species live where they live? What determines the abundance and diversity of species in a given area? What role do species play in the functioning of entire ecosystems? All of these questions share a single core concept—the ecological niche. Although the niche concept has fallen into disfavor among ecologists in recent years, Jonathan M. Chase and Mathew A. Leibold argue that the niche is an ideal tool with which to unify disparate research and theoretical approaches in contemporary ecology. Chase and Leibold define the niche as including both what an organism needs from its environment and how that organism's activities shape its environment. Drawing on the theory of consumer-resource interactions, as well as its graphical analysis, they develop a framework for understanding niches that is flexible enough to include a variety of small- and large-scale processes, from resource competition, predation, and stress to community structure, biodiversity, and ecosystem function. Chase and Leibold's synthetic approach will interest ecologists from a wide range of subdisciplines.

For many scholars, the study of community and community development is at a crossroads. Previously dynamic theories appear not to have kept pace with the major social changes of our day. Given our constantly shifting social reality we need new ideas and research that pushes the boundaries of our extant community theories. Theory, Practice, and Community Development stretches the traditional boundaries and applications of well-established community development theory, and establishes new theoretical approaches rooted in new disciplines and new perspectives on community development. Expanded from a special issue of the journal Community Development, Theory, Practice, and Community Development collects previously published and widely cited essays, as well as new theoretical and empirical research in community development. Compiled by the editors of Community Development, the essays feature topics as varied as placemaking, democratic theory and rural organizing. Theory, Practice, and Community Development is vital for scholars and practitioners coming to grips with the rapidly changing definition of community.
