How do fish populations regulate themselves? Why do some fish stocks flourish and then die away? These questions have fascinated fisheries scientists for decades, and in the last twenty years answers have begun to emerge. In this comprehensive 1995 account, David Cushing shows how the fate of fish larvae which live close to the centres of production in the sea has a crucial effect on population regulation. He shows how the timing and development of tidal fronts in particular regions has profound implications for fish and plankton production, which in turn affects fish recruitment. If recruitment of fish larvae into the pool of adult fish is insufficient, stocks may fail. It is only by understanding these processes that we can hope to recognise the implications of global climate change on marine populations. This book will be essential reading for all those interested in marine ecology and fisheries biology.
This established textbook continues to provide a comprehensive and stimulating introduction to marine ecological concepts and processes. Based on a wealth of international teaching expertise, An Introduction to Marine Ecology is written to be the basis for an entire undergraduate course in marine biology or ecology. It covers the trophic, environmental and competitive interactions of marine organisms, and the effects of these on the productivity, dynamics and structure of marine systems. The strength of the book lies in its discussion of core topics which remains at the heart of the majority of courses in the subject, despite an increasing emphasis on more applied aspects. The authors maintain the tradition of clarity and conciseness set by previous editions, and the text is extensively illustrated with colour plates, photographs and diagrams. Examples are drawn from all over the world. In this edition, the scientific content of the text has been fully revised and updated. An emphasis has been placed on human impacts, and completely new chapters have been added on fisheries, marine ecosystems, and human interference and conservation. Completely revised and updated with a twofold increase in the number of illustrations. Adopts a more applied approach in keeping with current teaching. New chapters on fisheries, the marine ecosystem, conservation and pollution. Based on a proven and successful course structure.
“A masterful accomplishment—Allen, Pondella and Horn have assembled a talented team of experts who produce authoritative, up-to-date accounts. This book will be used as the primary text in many fish biology courses and as a valuable reference elsewhere. Here is a wealth of data waiting to be mined by legions of graduate students as they generate the new ideas that will motivate marine ecology for years.”—Peter Sale, Editor of Coral Reef Fishes: Dynamics and Diversity in a Complex Ecosystem "A copiously illustrated and comprehensive interpretation of the past, present, and future state of over 500 species of fishes in Californian waters. A compilation of virtually all the many important studies on the ecology of California marine fishes."—Bruce B. Collette, National Marine Fisheries Service and co-author of The Diversity of Fishes
Case Studies for Integrating Science and the Global Environment is designed to help students of the environment and natural resources make the connections between their training in science and math and today's complex environmental issues. The book provides an opportunity for students to apply important skills, knowledge, and analytical tools to understand, evaluate, and propose solutions to today's critical environmental issues. The heart of the book includes four major content areas: water resources; the atmosphere and air quality; ecosystem alteration; and global resources and human needs. Each of these sections features in-depth case studies covering a range of issues for each resource, offering rich opportunities to teach how various scientific disciplines help inform the issue at hand. Case studies provide readers with experience in interpreting real data sets and considering alternate explanations for trends shown by the data. This book helps prepare students for careers that require collaboration with stakeholders and co-workers from various disciplines. - Includes global case studies using real data sets that allow readers to practice interpreting data and evaluating alternative explanations - Focuses on critical skills and knowledge, encouraging readers to apply science and math to real world problems - Employs a system-based approach, linking air, water, and land resources to help readers understand that cause-effect may be complex and solutions to environmental problems require multiple perspectives - Includes special features such as links to video clips of scientists at work, boxed information, a solutions section at the end of each case study, and practice exercises
Many of the processes influencing recruitment to an adult fish population or entry into a fishery occur very early in life. The variations in life histories and behaviours of young fish and the selective processes operating on this variation ultimately determine the identities and abundance of survivors. This important volume brings together contributions from many of the world's leading researchers from the field of fish ecology. The book focuses on three major themes of pressing importance in the analysis of the role that the early life history of fishes plays in the number and quality of recruits: the selective processes at play in their early life history; the contributions of early life history to the understanding of recruitment.
Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks. Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections: Biology, Population Dynamics and Recruitment Information Critical to Successful Assessment and Management Incorporation of Reproductive Biology and Recruitment Considerations into Management Advice and Strategies The authors collectively bring a wide range of diverse experience in areas of reproductive biology, fisheries oceanography, stock assessment, and management. Fully updated throughout, the book will be of great interest to a wide audience. It is useful as a textbook in graduate and undergraduate courses in fisheries biology, fisheries science, and fisheries resource management and will provide vital information for fish biologists, fisheries scientists and managers.
The world has seen dramatic changes since the publication of the first edition of The Oxford Companion to Politics of the World in 1993. In the post-Cold War world, globalization now offers wealth and opportunities on a broader scale, as well as greater international harmony, but threatens to reinforce the advantage gap between wealthy and poor regions and intensify environmental degradation. Conflict and squalor--expressed in brutal brushfire wars, epidemics, and chronic underdevelopment--vie with equally dramatic accounts of growth and democracy associated with a liberal political order and the global diffusion of trade, investment, and communications.Drawing on the breadth of the first edition, this updated edition reflects the changing world with a reassessment of many of the core themes of the Companion, and new articles on the people, concepts, and events that have shaped the world since 1993. The second edition includes biographies of Kofi Annan, Tony Blair, Bill Clinton, and Gerhard Schroder; articles on events such as the Rwandan Genocide and the war in Kosovo; and coverage of international trade developments such as NAFTA and the World Trade Organization. Eighty-seven of the 672 articles in the Second Edition are completely new; most others are thoroughly revised.This edition also features a substantial new set of articles, a dozen essays on critical issues written by influential figures. Recognizing the importance of including varying viewpoints, the editors have commissioned these essays to provide an informed and often passionate debate on controversial topics. Discussions include Lani Guinier and Glenn Loury on Affirmative Action; Francis Fukuyama and Milton Fisk on the Limits of Liberal Democracy; and Lloyd Axworthy and John Bolton on the United Nations.The contributors discuss nearly every nation in the world, including extensive information on institutions, political parties, leaders, and the sources of political mobilization and conflict. The volume also includes biographies of more than seventy-five political leaders and thinkers who have shaped the contemporary political world. Articles include detailed discussions of critical historical developments and events, concepts, international law, and organizations. The Oxford Companion to Politics of the World, Second Edition is an accessible, timely, thought-provoking, and comprehensive reference that captures the complexity and vitality of contemporary world affairs.
