Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: As researchers try to predict the effects of human modification at all trophic levels and mediate the impact of rapid environmental change, it has become clear it is no longer a matter of agreeing that both bottom-up and top-down forces play important roles in diverse ecosystems. Rather, the question is: how do these forces interact across aquatic and terrestrial systems? Written by leading experts in the field, this book presents a unique synthesis of trophic relationships within and across ecosystems that is a valuable foundation for the development of cross-system, multidisciplinary research. It also provides new insights into population biology and community ecology and examines the interactive effects of bottom-up and top-down forces on biodiversity at each trophic level. A one-stop resource for learning about bottom-up and top-down interactions, this book encourages discussion and collaboration among researchers to identify similarities and differences in trophic interactions across aquatic and terrestrial systems.

This book was released on 2003-12-08 with total page 1076 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Body Size: The Structure and Function of Aquatic Ecosystems written by Alan G. Hildrew and published by Cambridge University Press. This book was released on 2007-07-12 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists have long struggled to predict features of ecological systems, such as the numbers and diversity of organisms. The wide range of body sizes in ecological communities, from tiny microbes to large animals and plants, is emerging as the key to prediction. Based on the relationship between body size and features such as biological rates, the physics of water and the amount of habitat available, we may be able to understand patterns of abundance and diversity, biogeography, interactions in food webs and the impact of fishing, adding up to a potential 'periodic table' for ecology. Remarkable progress on the unravelling, describing and modelling of aquatic food webs, revealing the fundamental role of body size, makes a book emphasising marine and freshwater ecosystems particularly apt. In this 2007 book, the importance of body size is examined at a range of scales that will be of interest to professional ecologists, from students to senior researchers.

Book excerpt: "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.

Download or read book Ecological Modeling in Risk Assessment written by Robert A. Pastorok and published by CRC Press. This book was released on 2016-04-19 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxic chemicals can exert effects on all levels of the biological hierarchy, from cells to organs to organisms to populations to entire ecosystems. However, most risk assessment models express their results in terms of effects on individual organisms, without corresponding information on how populations, groups of species, or whole ecosystems may respond to chemical stressors. Ecological Modeling in Risk Assessment: Chemical Effects on Populations, Ecosystems, and Landscapes takes a new approach by compiling and evaluating models that can be used in assessing risk at the population, ecosystem, and landscape levels. The authors give an overview of the current process of ecological risk assessment for toxic chemicals and of how modeling of populations, ecosystems, and landscapes could improve the status quo. They present a classification of ecological models and explain the differences between population, ecosystem, landscape, and toxicity-extrapolation models. The authors describe the model evaluation process and define evaluation criteria. Finally, the results of the model evaluations are presented in a concise format with recommendations on modeling approaches to use now and develop further. The authors present and evaluate various models on the basis of their realism and complexity, prediction of relevant assessment endpoints, treatment of uncertainty, regulatory acceptance, resource efficiency, and other criteria. They provide models that will improve the ecological relevance of risk assessments and make data collection more cost-effective. Ecological Modeling in Risk Assessment serves as a reference for selecting and applying the best models when performing a risk assessment.

This book was released on 2006-07-26 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent scientific literature has raised many concerns about whether fisheries have caused more extensive changes to marine populations and ecosystems than previously realized or predicted. In many cases, stocks have been exploited far beyond management targets, and new analyses indicate that fishing has harmed other species—including marine mammals, seabirds, sea turtles, and sea grasses—either directly through catch or habitat damage, or indirectly through changes in food-web interactions. At the request of the National Oceanic and Atmospheric Administration, the National Research Council conducted an independent study to weigh the collective evidence for fishery-induced changes to marine ecosystems and the implications of the findings for U.S. fisheries management. Dynamic Changes in Marine Ecosystems provides comprehensive information in regard to these findings.

Download or read book Trophic Cascades written by John Terborgh and published by Island Press. This book was released on 2013-06-25 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
