Download or read book Marine Mussels written by Elizabeth Gosling and published by John Wiley & Sons. This book was released on 2021-12-01 with total page 892 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive volume providing broad and detailed coverage of marine mussels Marine Mussels: Ecology, Physiology, Genetics and Culture provides readers with in-depth, fully up-to-date information on all major aspects of marine mussels. Written by an internationally renowned expert in the field, this authoritative volume addresses morphology, ecology, ­feeding, phylogeny and evolution, reproduction and larval development, settlement and recruitment, genetics, disease, management of culture systems and more. The book encompasses many different species of marine mussels: genus Mytilus, other important commercial marine genera such as Perna, Aulacomya and Choromytilus, and non-commercial genera including Modiolus, Geukensia, Brachidontes and hydrothermal vent Bathymodiolus. Comprising twelve extensively cross-referenced chapters, the book discusses a diversity of integrated topics that range from fundamental physiology of marine mussels to new techniques being applied in their biology and ecology. Author Elizabeth Gosling reviews contemporary developments and issues in the field such as the use of DNA genetic markers in detecting and diagnosing different strains of pathogenic bacteria, the use of mussels as monitors of marine contaminants, sophisticated modelling techniques that simulate disease and forecast outbreaks, and the impacts of global warming, ocean acidification and hypoxia on marine mussels. Presenting an inclusive, highly detailed treatment of mussel biology, physiology, genetics, and culture, this invaluable resource: Contains thorough descriptions of external and internal anatomy, global and local distribution patterns, the impacts of mussels on marine ecosystems, and the processes of circulation, respiration, excretion and osmoregulation Reflects significant advances in mussel science and new areas of research in marine mussels Describes the fundamentals of mussel aquaculture, the types and levels of contaminants in the marine environment and new approaches for sustainable aquaculture development Discusses the application of genetic methods, population genetics, global breeding programmes and the emerging area of bivalve genomics Addresses the role of mussels in disease transmission to humans, including production and processing controls, regulation of monitoring and quality control Marine Mussels: Ecology, Physiology, Genetics and Culture is essential reading for biological scientists, researchers, instructors and advanced students in the fields of biology, ecology, aquaculture, environmental science, toxicology, genetics, pathology, taxonomy and public health.

Download or read book Bivalve Filter Feeders written by Richard F. Dame and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bivalve filter-feeding mollusks are important components of coastal ecosystems because they remove large quantities of suspended material from the water and excrete abundant amounts of reactive nutrients. These animals are also major prey for numerous predators including birds, fish, mammals, and invertebrates; furthermore, they are significant food resources for humans. While studies on the organismic and population level have dominated bivalve ecology, the recent focus on the ecosystem roles of filter feeding systems has led to larger-scale investigations. With this approach the specific topics of physiology, grazing, predation, nutrient cycling, physical environment, computer simulation modeling, and environmental management are combined into a meaningful whole.

Download or read book Aquaculture Health Management written by Frederick S.B. Kibenge and published by Academic Press. This book was released on 2020-06-13 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture Health Management: Design and Operation Approaches is an essential reference for the diverse aquaculture community. With the steadily increasing importance of healthy fish production and the expansion of the animal aquaculture industry to new geographic areas, new microbial and parasitic species with pathogenic potential continue to emerge. The book covers the broad spectrum of fish and shellfish health, the functional roles of pathogen emergence, and the impacts of nutrition and preventative medicine such as pre- and probiotics, as well as chemical treatments, relevant legislation and more. This reference takes a comprehensive approach to understanding overall fish health management, making it valuable to aquaculturists, practitioners in aquatic animal health, veterinarians and all those in industry, government or academia who are interested in aquaculture and fisheries and their sustainable futures. - Presents the biosecurity measures used to prevent the spread of disease - Discusses fish immunology to help readers understand preventive medicine for a healthy fish production - Examines the latest scientific methods and technologies to maximize efficiencies for healthy fish production for farming - Includes the most commonly researched fish, crustaceans and mollusks in aquaculture

Download or read book Visual Ecology written by Thomas W. Cronin and published by Princeton University Press. This book was released on 2014-08-10 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive treatment of visual ecology Visual ecology is the study of how animals use visual systems to meet their ecological needs, how these systems have evolved, and how they are specialized for particular visual tasks. Visual Ecology provides the first up-to-date synthesis of the field to appear in more than three decades. Featuring some 225 illustrations, including more than 140 in color, spread throughout the text, this comprehensive and accessible book begins by discussing the basic properties of light and the optical environment. It then looks at how photoreceptors intercept light and convert it to usable biological signals, how the pigments and cells of vision vary among animals, and how the properties of these components affect a given receptor's sensitivity to light. The book goes on to examine how eyes and photoreceptors become specialized for an array of visual tasks, such as navigation, evading prey, mate choice, and communication. A timely and much-needed resource for students and researchers alike, Visual Ecology also includes a glossary and a wealth of examples drawn from the full diversity of visual systems. The most up-to-date overview of visual ecology available Features some 225 illustrations, including more than 140 in color, spread throughout the text Guides readers from the basic physics of light to the role of visual systems in animal behavior Includes a glossary and a wealth of real-world examples

Download or read book Biology of Parrotfishes written by Andrew S. Hoey and published by CRC Press. This book was released on 2018-03-05 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parrotfish are found on almost every coral reef in the world. This ubiquity and uniqueness of their feeding action make them one of the most important groups of fishes within coral reef ecosystems. But why, exactly, are parrotfish so important to reefs? Can the evolution of a particular jaw morphology and feeding action really have had such a large impact on the health and functioning of the world's coral reefs? This book introduces the reader to this fascinating group of fishes (Labridae, Scarinae), from the morphological innovation of a jaw that has the power to bite through solid calcium carbonate, to the threats currently faced by parrotfish populations around the world. It contains new insights into their diet and food processing ability, and lifehistories, and concludes with an overview of emerging and future research directions.

Distributional information is provided per country, for larger or insular countries per subunits. An overview of fungus and slime mould hosts is annexed. The references to all taxa have been checked by the author. Infrasubspecific entities and priorities are dealt to comply with the ICZN. Nomenclatural problems are highlighted, and several new records are given. Extinct taxa are listed separately.
