Exploring the potential use of bivalves as indicators and monitors of ecosystem health, this book describes live and computer simulated experiments, mesocosm studies, and field manipulation experiments. This second edition discusses major new developments, including phase shifts in many coastal and estuarine ecosystems dominated by suspension-feeding bivalves, the invasion or introduction of alien bivalve species, the rapid growth of environmental restoration focused on bivalves, and the examination of geological history with regard to global climate change and its impact on bivalve-dominated systems.

A guide to the common marine bivalves of Alaska.--(Source of description unspecified.)

The aim of this open access book is to review and analyse the goods and services of bivalve shellfish. How they are defined, what determines the ecological functions that are the basis for the goods and services, what controversies in the use of goods and services exist, and what is needed for sustainable exploitation of bivalves from the perspective of the various stakeholders. The book is focused on the goods and services, and not on impacts of shellfish aquaculture on the benthic environment, or on threats like biotoxins; neither is it a shellfish culture handbook although it can be used in evaluating shellfish culture. The reviews and analysis are based on case studies that exemplify the concept, and show the strengths and weaknesses of the current applications. The multi-authored reviews cover ecological, economic and social aspects of bivalve goods and services. The book provides new insights for scientists, students, shellfish producers, policy advisors, nature conservationists and decision makers. This book is open access under the CC BY license.

Animal Energetics, Volume 2: Bivalvia through Reptilia is part of a two-volume treatise focusing on the integrated picture of the energy transformation process at the organismic level. Since it is almost impossible to restrict meaningful discussions to only one level of organization, some reference is made to population energetics as well as to the suborganismic level. The bioenergetics of both vertebrate and invertebrate groups are discussed. Specifically, the bioenergetics of bivalves, gastropods, bryozoans, pogonophorans, echinoderms, lower chordates, fishes, amphibians, and reptiles are covered. Understanding the efficient and fast transformation of biological energy has become an important issue in world affairs; studies on energetics and growth of thermoconformers can therefore be expected to expand greatly in the future. This book aims to provide many keys to a broader understanding of biology as well as open untrodden avenues to biologists with the quest for newer energy sources and efficient methods of energy utilization.

Marine Bivalve Molluscs is a comprehensive and thoroughlyupdated second edition of Bivalve Molluscs, covering allmajor aspects of this important class of invertebrates. As well asbeing an important class biologically and ecologically, many of thebivalves are fished and cultured commercially (e.g. mussels,oysters, scallops and clams) in a multi-billion dollar worldwideindustry. Elizabeth Gosling has written a landmark book that will stand formany years as the standard work on the subject. Chapters inMarine Bivalve Molluscs cover morphology, ecology, feeding,reproduction, settlement and recruitment, growth, physiology,fisheries, aquaculture, genetics, diseases and parasites, andpublic health issues. A full understanding of many of these aspectsis vital for all those working in bivalve fisheries andculture. An essential purchase for anyone concerned with this importantclass of animals, copies of Marine Bivalve Molluscs shouldbe on the shelves of biologists, ecologists, environmentalscientists, fisheries scientists and personnel within theaquaculture industry. Copies of the book should be available in alllibraries and research establishments where these subjects arestudied or taught.

U.S. mariculture production of bivalve molluscs-those cultivated in the marine environment-has roughly doubled over the last 25 years. Although mariculture operations may expand the production of seafood without additional exploitation of wild populations, they still depend upon and affect natural ecosystems and ecosystem services. Every additional animal has an incremental effect arising from food extraction and waste excretion. Increasing domestic seafood production in the United States in an environmentally and socially responsible way will likely require the use of policy tools, such as best management practices (BMPs) and performance standards. BMPs represent one approach to protecting against undesirable consequences of mariculture. An alternative approach to voluntary or mandatory BMPs is the establishment of performance standards for mariculture. Variability in environmental conditions makes it difficult to develop BMPs that are sufficiently flexible and adaptable to protect ecosystem integrity across a broad range of locations and conditions. An alternative that measures performance in sustaining key indicators of ecosystem state and function may be more effective. Because BMPs address mariculture methods rather than monitoring actual ecosystem responses, they do not guarantee that detrimental ecosystem impacts will be controlled or that unacceptable impact will be avoided. Ecosystem Concepts for Sustainable Bivalve Mariculture finds that while performance standards can be applied for some broad ecosystem indicators, BMPs may be more appropriate for addressing parameters that change from site to site, such as the species being cultured, different culture methods, and various environmental conditions. This book takes an in-depth look at the environmental, social, and economic issues to present recommendations for sustainable bivalve mariculture.

Diseases of Bivalves: Historical and Current Perspectives is a novel reference covering all known diseases of cultured and fished bivalve mollusks from around the world. Written by a renowned expert in the field of shellfish, the author presents a historical perspective of disease discovery, explaining when and where each disease first occurred and identified to current research findings. This reference describes the infectious agent that causes each disease and environmental conditions that promote infection symptoms and signs of the disease in the host, both as noted in individual animals and in the affected populations, and resultant morbidity and mortality of infected populations. The book offers past and current possible prevention and management methods to control disease in current and projected geographical locations. This is a complete resource for aquatic and veterinary pathologists, aquaculturists, government regulators, disease specialists and researchers, bivalve researchers, and students alike. Diseases include Metazoan Disease, Viral diseases, Fungal Disease, and more. - Presents microscopic visuals to illustrate the disease in bivalves - Includes graphs showing changes in disease prevalence and severity - Provides methods of diagnosis of infection by disease producing organisms

In 1968 when I forsook horticulture and plant physiology to try, with the help of Sea Grant funds, wetland ecology, it didn’t take long to discover a slim volume published in 1959 by the University of Georgia and edited by R. A. Ragotzkie, L. R. Pomeroy, J. M. Teal, and D. C. Scott, entitled “Proceedings of the Salt Marsh Conference” held in 1958 at the Marine Institute, Sapelo Island, Ga. Now forty years later, the Sapelo Island conference has been the major intellectual impetus, and another Sea Grant Program the major backer, of another symposium, the “International Symposium: Concepts and Controversies in Tidal Marsh Ecology”. This one re-examines the ideas of that first conference, ideas that stimulated four decades of research and led to major legislation in the United States to conserve coastal wetlands. It is dedicated, appropriately, to two then young scientists – Eugene P. Odum and John M. Teal – whose inspiration has been the starting place for a generation of coastal wetland and estuarine research. I do not mean to suggest that wetland research started at Sapelo Island. In 1899 H. C. Cowles described successional processes in Lake Michigan freshwater marsh ponds. There is a large and valuable early literature about northern bogs, most of it from Europe and the former USSR, although Eville Gorham and R. L. Lindeman made significant contributions to the American literature before 1960. V. J.

This report presents results of a study comparing the desiccation tolerance of D. gugensis and D. polimorpha, allowing analysis of the potential for dewatering to be an effective, nonchemical mitigation technology for both species. The results are also utilized to relate desiccation tolerance to differences in the depth distributions of the two species.
