Quantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work, why they sometimes fail, and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions, food webs, multi-species dynamics, risk-avoidance behavior, habitat selection and density-dependence. They treat fisheries policy development as a two-stage process, first identifying str...
The author spent much of 1989 and 1990 living within the Muscovite community and came into contact with people at all levels, from pimps to philosophers. He provides a portrait of a society which is struggling to survive the traumas and changes of the Gorbachev years. In some ways more medieval and Oriental than modern and Western, Moscow is a city in which tales of flying saucers and masonic conspiracies co-exist with endless queues, corruption, anti-semitism and a black market in guns. Durden-Smith also discovered in Moscow an intellectual passion and energy which puts most Western capitals to shame and which makes Moscow not only one of the most important, but also one of the most complex, contradictory and fascinating cities on earth.
This book really began in 1980 with our first microcomputer, an Apple II +. The great value of the Apple II + was that we could take the computer programs we had been building on mainframe and mini-computers, and make them available to the many fisheries biologists who also had Apple II + 's. About 6 months after we got our first Apple, John Glaister came through Vancouver and saw what we were doing and realized that his agency (New South Wales State Fisheries) had the same equipment and could run the same programs. John organized a training course in Australia where we showed about 25 Australian fisheries biologists how to use microcomputers to do many standard fisheries analyses. In the process of organizing this and sub sequent courses we developed a series of lecture notes. Over the last 10 years these notes have evolved into the chapters of this book.
In this classic text first published in 1986, Walters challenges the traditional approach to dealing with the management of such renewable resources as fish and wildlife. He argues that scientific understanding will come from the experience of management as an ongoing, adaptive, and experimental process.
The 31 chapters provide a wealth of previously unpublished information, plus topic syntheses, for a wide range of ecological parameters. These include the physical driving forces that created and continue to shape the Everglades and patterns and processes of its flora and fauna. The book summarizes recent studies of the region's vegetation, alligators, wading birds, and endangered species such as the snail kite and Florida panther. This referee-reviewed volume is the product of collaboration among 58 international authors from 27 institutional affiliations over nearly five years. The book concludes with a synthesis of system-wide restoration hypotheses, as they apply to the Everglades, that represent the integration and a collective viewpoint from the preceding 30 chapters. Techniques and systems learned here can be applied to ecosystems around the world.
"With clarity and grace, Stephen Bocking tackles the complicated question of the role of scientific expertise in environmental policy making. Nature’s Experts is a timely and important book."—David H. Guston, author of Between Politics and Science: Assuring the Integrity and Productivity of Research "This book by Stephen Bocking is as much about deliberative democracy as it is about science and the environment. Stephen Bocking’s treatment is deep, perceptive, and profoundly wise. He has caught the heart of present and future environmental science, politics, and democratic governance."—C. S. Holling, The Resilience Alliance and emeritus professor, Arthur R. Marshall Jr. Chair in Ecolo...
This book examines the practices of contesting evidence in democratically constituted knowledge societies. It provides a multifaceted view of the processes and conditions of evidence criticism and how they determine the dynamics of de- and re-stabilization of evidence. Evidence is an essential resource for establishing claims of validity, resolving conflicts, and legitimizing decisions. In recent times, however, evidence is being contested with increasing frequency. Such contestations vary in form and severity – from questioning the interpretation of data or the methodological soundness of studies to accusations of evidence fabrication. The contributors to this volume explore which actors,...
The Millennium Development Goals, adopted at the UN Millennium Summit in 2000, are the world's targets for dramatically reducing extreme poverty in its many dimensions by 2015 income poverty, hunger, disease, exclusion, lack of infrastructure and shelter while promoting gender equality, education, health and environmental sustainability. These bold goals can be met in all parts of the world if nations follow through on their commitments to work together to meet them. Achieving the Millennium Development Goals offers the prospect of a more secure, just, and prosperous world for all. The UN Millennium Project was commissioned by United Nations Secretary-General Kofi Annan to develop a practica...

For thousands of years, fisheries were crucial to the sustenance of the First Peoples of the Pacific Coast. Yet human impact has left us with a woefully incomplete understanding of their histories prior to the industrial era. Covering Alaska, British Columbia, and Puget Sound, The Archaeology of North Pacific Fisheries illustrates how the archaeological record reveals new information about ancient ways of life and the histories of key species. Individual chapters cover salmon, as well as a number of lesser-known species abundant in archaeological sites, including pacific cod, herring, rockfish, eulachon, and hake. In turn, this ecological history informs suggestions for sustainable fishing in today’s rapidly changing environment.
