First published 1984. The intent of the authors in organizing a AAAS symposium and this subsequent volume was to integrate the findings of aquatic ecologists whose research spans the first three trophic levels (algae, zooplankton and fish) of both marine and freshwater environments. Major topics (phytoplankton, zooplankton, fish and community interactions) are presented as, at least, two trophic-level associations by scientists who have distinctly differing perspectives. The format of papers varies from review to research and was chosen by authors on the basis of suitability to their specific topic.

At last both ecology and evolution are covered in this study on the dynamics of size-structured populations. How does natural selection shape growth patterns and life cycles of individuals, and hence the size-structure of populations? This book will stimulate biologists to look into some important and interesting biological problems from a new angle of approach, concerning: - life history evolution, - intraspecific competition and niche theory, - structure and dynamics of ecological communities.

In Asia, the fisheries sector is important in terms of food security, livelihoods and foreign exchange earnings. However, as in many parts of the world, there are signs that capture fisheries are fully exploited or overfished. Management of fisheries in the region is often hampered by lack of information on the status of fisheries in terms of biological, social, economic, policy and governance aspects. This regional project documents an alarming decline on coastal fishery resources, based on historic research surveys in South and Southeast Asia. Socio-economic analyses and policy reviews highlight the importance of the fisheries sector but also the challenges facing it. Potential interventions to improve fisheries management in the countries are outlined and defined with environmental, socioeconomic and institutional objectives.

Ecosystem analysis and ecological modelling is a rapidly developing interdisciplinary branch of science used in theoretical developments in ecology and having practical applications in environmental protection. In this book, the authors introduce new holistic, particularly cybernetic, concepts into ecosystem theory and modelling, and provide a concise treatment of mathematical modelling of freshwater ecosystems which covers methods, subsystem models, applications and theoretical developments. Part I begins with a brief introduction to the principles of systems theory and their applications to ecosystems, and provides a summary of various methods of systems analysis. In Part II emphasis is laid on the pelagic processes in standing water, characterised by relatively uninvolved structures from which models can be readily developed. Part III describes applications of the technique of modelling to solutions of theoretical and practical problems, with different modelling methods and objectives being used in the various chapters. More recent developments in the methods and theory of ecosystem modelling are covered in Part IV which also includes a discussion of future trends. The book is addressed to practising ecologists and engineers in the fields of ecology, limnology, environmental protection, and water quality managements, as well as to graduate/post-graduate university students in science and engineering. Students and researchers involved in environmental applications of mathematics and cybernetics will also find the book of interest.

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.

"Daniel Pauly is a friend whose work has inspired me for years." —Ted Danson, actor, ocean activist, and co-author of Oceana "This wonderfully personal and accessible book by the world’s greatest living fisheries biologist summarizes and expands on the causes of collapse and the essential actions that will be required to rebuild fish stocks for future generations.” —Dr. Jeremy Jackson, ocean scientist and author of Breakpoint The world’s fisheries are in crisis. Their catches are declining, and the stocks of key species, such as cod and bluefin tuna, are but a small fraction of their previous abundance, while others have been overfished almost to extinction. The oceans are depleted and the commercial fishing industry increasingly depends on subsidies to remain afloat. In these essays, award-winning biologist Dr. Daniel Pauly offers a thought-provoking look at the state of today’s global fisheries—and a radical way to turn it around. Starting with the rapid expansion that followed World War II, he traces the arc of the fishing industry’s ensuing demise, offering insights into how and why it has failed. With clear, convincing prose, Dr. Pauly draws on decades of research to provide an up-to-date assessment of ocean health and an analysis of the issues that have contributed to the current crisis, including globalization, massive underreporting of catch, and the phenomenon of “shifting baselines,” in which, over time, important knowledge is lost about the state of the natural world. Finally, Vanishing Fish provides practical recommendations for a way forward—a vision of a vibrant future where small-scale fisheries can supply the majority of the world’s fish.

Aquatic Functional Biodiversity: An Ecological and Evolutionary Perspective provides a general conceptual framework by some of the most prominent investigators in the field for how to link eco-evolutionary approaches with functional diversity to understand and conserve the provisioning of ecosystem services in aquatic systems. Rather than producing another methodological book, the editors and authors primarily concentrate on defining common grounds, connecting conceptual frameworks and providing examples by a more detailed discussion of a few empirical studies and projects, which illustrate key ideas and an outline of potential future directions and challenges that are expected in this interdisciplinary research field. Recent years have seen an explosion of interest in using network approaches to disentangle the relationship between biodiversity, community structure and functioning. Novel methods for model construction are being developed constantly, and modern methods allow for the inclusion of almost any type of explanatory variable that can be correlated either with biodiversity or ecosystem functioning. As a result these models have been widely used in ecology, conservation and eco-evolutionary biology. Nevertheless, there remains a considerable gap on how well these approaches are feasible to understand the mechanisms on how biodiversity constrains the provisioning of ecosystem services. Defines common theoretical grounds in terms of terminology and conceptual issues Connects theory and practice in ecology and eco-evolutionary sciences Provides examples for successful biodiversity conservation and ecosystem service management

Expanding the risk assessment toolbox, this book provides a comprehensive and practical evaluation of specific ecological models for potential use in risk assessment. Ecological Modeling in Risk Assessment: Chemical Effects on Populations, Ecosystems, and Landscapes goes beyond current risk assessment practices for toxic chemicals as applied to individual-organism endpoints to describe ecological effects models useful at the population, ecosystem, and landscape levels. The authors demonstrate the utility of a set of ecological effects models, eventually improving the ecological relevance of risk assessments and making data collection more cost effective.
