The Provident Sea describes the history of fish stock management (including whales and seals). The book traces, on the basis of the original scientific material, the history of the management of "the provident sea" up to recent times when problems of over-exploitation have had dramatic effects upon stocks. The need for management arose mainly from the increasing industrialization of capture. Hence the preindustrial fisheries are covered, in particular the old cod fishery on the Grand Bank and the herring fishery in the North Sea, as an essential background to current problems. The origins of fisheries and whaling science are described, as is the development up to 1965 of the science and institution in fisheries, whaling, and sealing. In the sixties and seventies, certain major fishing nations took a heavy harvest of fish stocks using sophisticated and efficient gathering methods. This in turn led to conflict and one consequence was the "Law of the Sea" conference set up to try and resolve these issues.
Seagrasses occur in coastal zones throughout the world, in the part of the marine habitat that is most heavily influenced by humans. Decisions about coastal management therefore often involve seagrasses, but despite a growing awareness of the importance of these plants, a full appreciation of their role in coastal ecosystems has yet to be reached. This book provides an entry point for those wishing to learn about their ecology, and gives a broad overview of the state of knowledge, including progress in research and research foci, complemented by extensive literature references to guide the reader to more detailed studies. It will be valuable to students of marine biology wishing to specialize in this area and also to established researchers wanting to enter the field. In addition, it will provide an excellent reference for those involved in the management and conservation of coastal areas that harbour seagrasses.
Our current knowledge of marine organisms and the factors affecting their ecology, distribution and evolution has been revolutionised by the use, in the last 20 years, of molecular population genetics tools. This book is the result of a meeting of world-leading experts, in Rio de Janeiro, where the state of the art of this field was reviewed. Topics covered include the molecular analysis of bio-invasions, the recent developments in marine biotechnology, the factors affecting levels of genetic variation and population structure in marine organisms and their application to conservation biology, fisheries and aquaculture. This is the first book dedicated to the genetic study of marine organisms. It will be very useful to biology students, scientists and anyone working or simply interested in areas such as marine biology, zoology, ecology, and population and molecular genetics.
This volume is based on the proceedings of a conference held at Florida State University in April, 1978. This conference was supported by the Florida State University Graduate Research Council, the Department of Biological Science (F. S. U. ), and the Center for Professional Development and Public Service. Particular recogni tion should be made of the efforts of Dr. Anne Thistle in the organization of the conference and the completion of this book. Julia K. White and Sheila Marrero produced the typescript. The principal objective of the conference was to assemble a group of marine scientists from diverse disciplines to discuss the state of marine ecology with particular attention to new research directions based on previous studies. Emphasis was placed on the integration of different research approaches and on the application of established procedures to various environmental problems. An effort was made to eliminate traditional disciplinary boundaries which often hinder our understanding of marine systems. There was generally wide latitude for review and speculation concerning such topics as physico-chemical processes, productivity and trophic interactions, population distribution and community structure, and natural or anthropogenic disturbance phenomena. Throughout, the usual miniaturization of the scope of discussion was subordinate to a frank appraisal of the present status of marine research. Although many introductory ecological texts stress the so called ecosystem approach, individual marine research projects seldom encompass this broad course. There is, in fact, a real need for system-wide studies at both the theoretical and applied levels."
Combining background knowledge and practical tools, Handbook of Inland Aquatic Ecosystem Management gives you an overview of how to manage inland waters in a holistic manner. It examines the problems that threaten aquatic inland water ecosystems and presents a set of toolboxes for solving them. The book focuses on lakes, reservoirs, ponds, rivers, wetlands, lagoons, and estuaries, including the predominant freshwater ecosystems as well as saline and brackish ecosystems. Understand Ecosystem Properties and Ecological Processes The book consists of two parts. The first part reviews the basic scientific knowledge needed in the environmental and ecological management of aquatic ecosystems, from limnology and ecology of inland water ecosystems to environmental physics and chemistry. It emphasizes the interacting processes that characterize all inland aquatic ecosystems and explains the scientific considerations behind the conservation principles and their applications. Define the Problems and Quantify Their Sources The second part of the book presents toolboxes that you can apply to achieve more holistic environmental and ecological management. After an overview of the environmental problems of inland aquatic ecosystems and their sources, the book examines toolboxes to help you identify the problem, namely mass balances, ecological indicators, and ecological models. It also discusses toolboxes that can be used to find an environmental management solution to the problem: environmental technology, cleaner technology, and ecotechnology. Integrate Science and Practical Toolboxes to Manage Inland Waters More Effectively This book shows you how to integrate biology, ecology, limnology, and chemistry with the toolboxes in an up-to-date, multidisciplinary approach to environmental management. It provides a powerful framework for identifying ecological mechanisms that interact with global environmental problems threatening inland aquatic ecosystems.
A thorough understanding of planktonic organisms is the first step towards a real appreciation of the diversity, biology, and ecological importance of marine life. A detailed knowledge of their distribution and community composition is particularly important since these organisms are often very delicate and sensitive to change, and can be used as early indicators of environmental change. Natural and man-induced modification of the environment can affect both the distribution and composition of plankton, with important ecological and economic impacts. Marine Plankton provides a practical guide to plankton biology with a large geographic coverage spanning the North Sea to the north-eastern Atlantic coast of the USA and Canada. The book is divided into three sections: an overview of plankton ecology, an assessment of methodology in plankton research covering sampling, preservation, and counting of samples, and a taxonomic guide richly illustrated with detailed line drawings to aid identification. This is an essential reference text suitable for senior undergraduate and graduate students taking courses in marine ecology (particularly useful for fieldwork) as well as for professional marine biologists. It will also be of relevance and use to environmental scientists, conservation biologists, marine resource managers, environmental consultants, and other specialised practitioners.
This 1997 book is about those animals found on the sea floor that live by filtering microscopic particles carried to them by water currents. Its purpose is to review what is known about the biology of suspension feeders in relation to their flow environment. The book includes the larval biology, physiology, ethology and ecology of suspension feeders interacting with water flow. It will be of value to marine scientists beginning research in the interdisciplinary field of hydrodynamics and benthic biology, and it is the first attempt to provide a comprehensive overview of this synthesis from the biological viewpoint.
The biodiversity of many ecosystems is under threat and although seas cover the majority of our planet's surface, far less is known about the biodiversity of marine environments than that of terrestrial systems. It is also not clear whether many of the patterns known to occur on land also occur in the sea. Until we have a firmer idea of the diversity of a wide range of marine habitats and what controls it, we have little hope of conserving biodiversity, or determining the impact of human activities such as mariculture, fishing, dumping of waste and pollution. This book brings together key studies from the deep sea and open ocean, to tropical shores and polar regions to consider how comparable the patterns and processes underlying diversity are in these different ecosystems. Marine Biodiversity will be a major resource for all those interested in biodiversity and its conservation.
As in the terrestrial environment, most data collection from freshwater habitats to date falls into the survey, surveillance or research categories. The critical difference between these exercises and a monitoring project is that a monitoring project will clearly identify when we need to make a management response. A Model for Conservation Management and Monitoring Monitoring (as defined by Hellawell) is essentially a tool of practical conservation management, and Fig. 1.1 shows a simple, but effective, model for nature conser- tion management and monitoring. The need for clear decision-making is implicit in this model. First we must decide what would represent a favourable state for the key habitat or species, and then we must decide when to intervene if the state is (or becomes) unfavourable. A third, often overlooked, but equally important, decision concerns when we would consider the habitat or species to have recovered; this is unlikely to be the same point that we became concerned about it. This decision not only has resource imp- cations, it can also have major implications for other habitats and species (prey species are an obvious example). All of these decisions are essential to the devel- ment of an efficient and effective monitoring project.

The sea is host to most of the Earth's biodiversity. However, in the case of parasites and their hosts, little is known of the interactions among the organisms. This important volume covers many aspects of these interactions, including the co-evolution and biogeography of different marine systems, and their applied impact on commercially important host species. Topics discussed include species interactions in such well-studied systems as larval trematodes in gastropods and ectoparasites on fish. The effects of parasites in ecosystems extend to commercial, economic concerns, particularly in aquaculture. The volume presents an easy-to-read account of recent advances in this important topic.
Siberia's Lake Baikal is one of nature's most magnificent creations, the largest and deepest body of fresh water in the world. And yet it is nearly unknown outside of Russia. In Sacred Sea--the first major journalistic examination of Baikal in English--veteran environmental writer Peter Thomson and his younger brother undertake a kind of pilgrimage, journeying 25,000 miles by land and sea to reach this extraordinary lake. At Baikal they find a place of sublime beauty, deep history, and immense natural power. But they also find ominous signs that this perfect eco-system--containing one-fifth of earth's fresh water and said to possess a mythical ability to cleanse itself--could yet succumb to the even more powerful forces of human hubris, carelessness, and ignorance. Ultimately, they help us see that despite its isolation, Baikal is connected to everything else on Earth, and that it will need the love and devotion of people around the world to protect it.
Acknowledging the present inability to determine objectively the status and trends among estuarine ecosystems, the environmental research community has recently stepped up efforts to develop and evaluate meaningful estuarine indicators. This goal requires the effort of researchers from a broad spectrum of disciplines. In order to expedite this initiative, many of the world's leading estuarine scientists came together to present their views at the 2003 Estuarine Indicators Workshop. Derived from this conference of leading estuarine scientists, Estuarine Indicators presents the principles, concepts, practical use, and application of indicators in estuarine research and management practices. Topics include: the theory behind environmental indicators and their presumed attributes; the methods and protocols of indicator development and evaluation; a presentation of effective and ineffective indicator examples; and discussions of the future directions in research and management practices. This is an ideal reference for researchers, scientists, and students from any field dealing with estuaries and estuarine ecosystems. Its introductory-level chapters are accessible to novices and seasoned experts alike, and the applications and interpretation of research data suit the needs of environmental managers. This is a truly multidisciplinary, comprehensive compendium upon which future research will undoubtedly be built.
Here is a comprehensive review of the ecology of freshwater bivalves and gastropods worldwide. Robert Dillon discusses the ecology of these species in its broadest sense, including diet, habitat, and reproductive biology to emphasize the tremendous diversity of these freshwater invertebrates. He develops a new life history model that unifies them and reviews their population and community ecology, treating competition, predation, parasitism, and biogeography. Extensively referenced and synthesizing work from the nineteenth century through to the present day, this book includes original analyses that unify previous work into a coherent whole.
Coral reefs are an important tourism resource for many coastal and island destinations and generate a range of benefits to their local communities, including as a food source, income from tourism, employment and recreational opportunities. However, coral reefs are under increasing threat from climate change and related impacts such as coral bleaching and ocean acidification. Other anthropogenic stresses include over-fishing, anchor damage, coastal development, agricultural run-off, sedimentation and coral mining. This book adopts a multidisciplinary approach to review these issues as they relate to the sustainable management of coral reef tourism destinations. It incorporates coral reef science, management, conservation and tourism perspectives and takes a global perspective of coral reef tourism issues covering many of the world's most significant coral reef destinations. These include the Great Barrier Reef and Ningaloo Reef in Australia, the Red Sea, Pacific Islands, South East Asia, the Maldives, the Caribbean islands, Florida Keys and Brazil. Specific issues addressed include climate change, pollution threats, fishing, island tourism, scuba diving, marine wildlife, governance, sustainability, conservation and community resilience. The book also issues a call for more thoughtful development of coral reef experiences where the ecological needs of coral reefs are placed ahead of the economic desires of the tourism industry.

During the last few years, lake acidification has become a topic of international interest because of the detrimental effects of this problem on lake ecosystems. The stratigraphic record of diatoms and other paleoindicators in lake sediments has been used increasingly to document past limnological conditions. Because many diatom taxa are sensitive indicators of lakewater pH, this approach is especially useful in assessing impacts of atmospheric pollutants and watershed land use on lake pH. The idea that a book be prepared on this subject originated at a workshop entitled 'Reconstructing pH from sedimentary diatom remains - recent insights and update on methods' organized by R.B. Davis and held at the XXII Congress of the International Association of Limnology at Lyon, France in August 1983. At this workshop, presentations were made by many of the authors in this volume. The rapid progress in this field was evident when a second workshop, this time organized by R.W. Battarbee and R.J. Flower, was held one year later at the VII International Symposium on Diatoms at Paris, France. Many individuals helped with the preparation of this volume, most notable were our referees, who thoughtfully reviewed the manuscripts and suggested many improvements. I would also like to thank my colleagues at Queen's University who helped in innumerable ways over the last two years. A special word of gratitude is due to Dr. M.M. Boucherle, Dr. S.R. Brown, Ms. T.C. Oliver, and Mr. P.R. Leavitt. J.
Coral communities are among the most fascinating of all biotic assemblages on earth. It is their rich diversity and the strong biological interactions which characterize these communities that provides the focus for this book. Here I describe patterns of diversity, species interactions, and community organization as well as the processes which influence these structural attributes. Although this treatment of the subject will to some degree blend evolutionary and ecological phenomena, I am primarily interested in the dynamic properties of living coral communities. Hence, such processes as succession, competition, predation, herbivory, and disturbances will be emphasized in ecological terms, but not to the exclusion of evolutionary considerations. The former influence the maintenance of diversity in coral communities and local distribution and abundance patterns. The latter deal primarily with the origins of diversity, adaptations to the local environment, biogeographic distributions, and longevity in the fossil record. With the recent resurgence of interest in historical and large-scale geographical effects on the local diversity of ecological communities, ecological and evolutionary perspectives are beginning to be integrated into our understanding of community organization and dynamics. Hence, a synthesis of these perspectives is attempted in the final chapter of this book. This effort emerges as a consequence of academic experiences, research interests, and the strong influence of several individuals. My first exposure to ecology occurred at Pomona College where three faculty members guided my early explorations into this subject.
Reviews: Methods and Technology in Fish Biology and Fisheries published by Kluwer Academic Publishers is a book series dedicated to the publication of information on advanced, forward-looking methodologies, technologies, or perspectives in fish and is especially dedicated to relevant topics addressing global, fisheries. This series international concern in fish and fisheries. Humans continue to challenge our environments with new technologies and technological applications. The dynamic creativity of our own species often tends to place the greatest burden on our supporting ecosystems. This is especially true for aquatic networks of creeks, lakes, rivers and ocean environments. We also frequently use our conceptual powers to balance conflicting requirements and demands on nature and continue to develop new approaches and tools to provide sustainable resources as well as conserve what we hold most dear on local and global scales. This book series will provide a window into the developing dynamic among humans, aquatic ecosystems (both freshwater and marine), and the organisms that inhabit aquatic environments. There are many reasons to doubt the increasing social and economic value technology has gained over the last two centuries. Science and technology represent stages in human development. I agree with Ernst Mayer when he said in Toward a New Philosophy of Biology (1988) that "endeavors to solve all scientific problems by pure logic and refined measurements are unproductive, if not totally irrelevant.
Red Snapper Lutjanus campechanus, is an important commercial and recreational fish species and there has been much interest in maintaining its status among a variety of scientific, social and economic levels. Stocks are influenced by varying environmental conditions, changing fishing effort and efficiency, anthropogenic effects, inter- and intraspecific interactions, bycatch from other fisheries, and habitat alterations. Red Snapper Biology in a Changing World explores these changing factors and their potential effects on Red Snapper in the Eastern Atlantic region including the Gulf of Mexico and Southeastern U.S. The book will provide a better understanding of Red Snapper population fluctuations that will subsequently allow for better management decisions and more informed user groups in their efforts to maintain a sustainable fishery. It explores the responses Red Snapper have made, and are making, relative to their life history attributes such as early life history and adult ecology, especially attributes associated with population distribution and abundance, movement patterns, fish health issues and management success. A compendium of many papers presented at the 147th annual meeting of the American Fisheries Society in Tampa, Florida, this volume also includes additional research completed as a result of the symposium. It will be essential reading for fisheries scientists and managers, ichthyologists, resource and environmental managers, and policymakers who are involved with coastal fisheries.
Lake Issyk-Kul is a closed lake located in the Tien Shan mountain
belt of the Republic of Kyrgyzstan. It is the world's fifth deepest
lake (668 m) and the second largest high altitude lake in the world
(1607 m above sea level). The lake is affected by several
environmental threats of both anthropogenic and natural origin:
decline of the lake level resulting in progressively increasing
salinity, incomplete vertical water exchange, and risk of
contamination by past and present industrial activity.
Brackish water can be found wherever sea water is diluted by freshwater to form water of intermediate salinity. The ephemeral habitats of estuaries, coastal lagoons and inland seas are rich in fauna, but are threatened by rising sea levels, drainage and reclamation of low lying coastal land, storms and sea defences. This is the first identification guide to the fauna of these ecologically important areas. The ecology of these animals and their habitats are examined and reviewed. The keys are designed to be used with living material, and illustrations are provided for all species likely to be found in brackish-water habitats in northwestern Europe, making identification easy. Fieldworkers, naturalists and students interested in these fragile and ephemeral habitats will find this an indispensable reference.
