Download or read book Quantitative Fish Dynamics written by Terrance J. Quinn and published by Oxford University Press, USA. This book was released on 1999 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fields of fish population dynamics and stock assessment have seen major advances in the 1980s and 1990s, creating the need for a new synthesis. This text attempts that synthesis by presenting a contemporary approach for quantitative fisheries science that incorporates modern statistical and mathematical techniques. It emphasizes the link between biology and theory by explaining the assumptions inherent in the quantitative methods and models. The book covers key topics that are often overlooked in other texts, such as optimal harvesting, migratory stocks, and complex age and size-structured models. Quantitative Fish Dynamics is an ideal textbook for graduate and undergraduate courses in fish population dynamics and stock assessment. It is an indispensable reference work for fisheries scientists and others interested in conservation biology, fish and wildlife management, population ecology, and statistical applications.

Download or read book Fish Population Dynamics Monitoring and Management written by Ichiro Aoki and published by Springer. This book was released on 2018-05-22 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores how we can solve the urgent problem of optimizing the use of variable, uncertain but finite fisheries resources while maintaining sustainability from a marine-ecosystem conservation perspective. It offers readers a broad understanding of the current methods and theory for sustainable exploitation of fisheries resources, and introduces recent findings and technological developments. The book is divided into three parts: Part I discusses fish stock dynamics, and illustrates how ecological processes affecting life cycles and biological interactions in marine environments lead to fish stock variability in space and time in major fish groups; small pelagic fish, demersal fish and large predatory fish. These insights shed light on the mechanisms underlying the variability in fish stocks and form the essential biological basis for fisheries management. Part II addresses the technologies and systems that monitor changes in fisheries resources and marine ecosystems using two approaches: fishery-dependent and fishery-independent data. It also describes acoustic surveys and biological sampling, as well as stock assessment methods. Part III examines management models for effectively assessing the natural variability in fisheries resources. The authors explore ways of determining the allowable catch in response to changes in stock abundance and how to incorporate ecological processes and monitoring procedures into management models. This book offers readers a broad understanding of sustainable exploitation as well as insights into fisheries management for the next generation.

Download or read book Ethology and Behavioral Ecology of Odontocetes written by Bernd Würsig and published by Springer. This book was released on 2019-08-02 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.

Download or read book Taking the Temperature of the Earth written by Glynn Hulley and published by Elsevier. This book was released on 2019-06-15 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking the Temperature of the Earth: Steps towards Integrated Understanding of Variability and Change presents an integrated, collaborative approach to observing and understanding various surface temperatures from a whole-Earth perspective. The book describes the progress in improving the quality of surface temperatures across different domains of the Earth's surface (air, land, sea, lakes and ice), assessing variability and long-term trends, and providing applications of surface temperature data to detect and better understand Earth system behavior. As cooperation is essential between scientific communities, whose focus on particular domains of Earth's surface and on different components of the observing system help to accelerate scientific understanding and multiply the benefits for society, this book bridges the gap between domains. - Includes sections on data validation and uncertainty, data availability and applications - Integrates remote sensing and in situ data sources - Presents a whole earth perspective on surface temperature datasets, delving into all domains to build and understand relationships between the datasets

Download or read book Marine Mammal Welfare written by Andy Butterworth and published by Springer. This book was released on 2017-06-19 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals attract human interest – sometimes this interest is benign or positive – whale watching, conservation programmes for whales, seals, otters, and efforts to clear beaches of marine debris are seen as proactive steps to support these animals. However, there are many forces operating to affect adversely the lives of whales, seals, manatees, otters and polar bears – and this book explores how the welfare of marine mammals has been affected and how they have adapted, moved, responded and sometimes suffered as a result of the changing marine and human world around them. Marine mammal welfare addresses the welfare effects of marine debris, of human traffic in the oceans, of noise, of hunting, of whale watching and tourism, and of some of the less obvious impacts on marine mammals – on their social structures, on their behaviours and migration, and also of the effects on captivity for animals kept in zoos and aquaria. There is much to think and talk about – how marine mammals respond in a world dramatically influenced by man, how are their social structures affected and how is their welfare impacted?

Download or read book Frogfishes written by Theodore W. Pietsch and published by JHU Press. This book was released on 2020-03-03 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authoritative expert's guide to fascinating frogfishes and their unusual lives. Winner of the PROSE Award for Best Single Volume Reference in Science by the Association of American Publishers Unique among the world's fishes, frogfishes display a bizarre combination of attributes and behaviors that make them a subject of fervent study. Through cunning and trickery, they turn would-be predators into prey; they "walk" across the ocean floor and jet-propel through open water; some lay their eggs in a floating mucoid mass, while others employ complex patterns of parental care; and they are certainly among the most colorful of nature's productions. In Frogfishes, two of the world's leading anglerfish experts, Theodore W. Pietsch and Rachel J. Arnold, bring together an enormous amount of information about these incredible creatures. The only detailed exploration of frogfishes in print, the book touches on everything from their morphology and biomechanics to their diets and habitats. Enhanced with more than 500 spectacular color images, the book also includes • a thorough look at about 5,000 preserved specimens; • an annotated synonymy for all extant taxa, as well as keys and tables to facilitate identification; • insights into frogfish feeding, locomotion, mimicry, and reproductive behavior; • descriptions of recent scientific advances, including the discovery of new species, shifts in geographic distribution, and emerging DNA sequencing techniques; and • tips for frogfish-seeking divers and aquarists that emphasize conservation. Unmasking the mysteries of frogfish evolution and phylogenetic relationships through close examination of their fossil record, morphology, and molecular reconstruction, Frogfishes demonstrates the surprising diversity and beauty of this remarkable assemblage of marine shorefishes.
