Download or read book The Economics of Protected Marine Species Concepts in Research and Management written by Kristy Wallmo and published by Frontiers Media SA. This book was released on 2016-10-21 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protected marine species have populations that are depleted, decreasing, or are at-risk of extinction or local extirpation. As of 2015 The International Union for the Conservation of Nature, a global environmental organization, lists approximately 737 marine species worldwide that are considered at risk of extinction. Many are provided legal protection through national laws requiring research and management measures aimed at recovering and maintaining the species at a sustainable population level. Integral to the policy decision process involving the management and recovery of marine species is the consideration of trade-offs between the economic and ecological costs and benefits of protection. This suggests that economics, at its core the study of trade-offs, has a significant role. In the U.S. a somewhat traditional use of economics in protected species research and management has involved cost minimization or cost-effectiveness analyses to help select or prioritize conservation actions. Economic research has also provided estimates of public non-market benefits of recovering species, which can be used in larger management frameworks such as ecosystem based management and coastal and marine spatial planning. Inherent in much of this research, however, are complex biological and ecological relationships in which varying degrees of scientific uncertainty are present. Addressing this type of uncertainty can affect the economic outcomes related to protected species. For example, recent work suggests that increasing scientific precision in biological sampling and models can greatly affect the magnitude of economic benefits to commercial fisheries, while other research suggests that public non-market benefits of species recovery are sensitive to uncertainty about baseline population estimates. Previous research has illustrated the importance of understanding the biological, ecological, and economic aspects of protected species management and recovery. In this research topic we synthesize current protected marine species economic research and expand the discussion on present and future challenges related to protected species economics. The series of manuscripts brings together an array of prominent researchers and advances our understanding of the ecological and economic aspects of managing and recovering protected marine species.
Download or read book A Guide to the Rockfishes Thornyheads and Scorpionfishes of the Northeast Pacific written by John Lawton Butler and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is an exciting book for those who have an interest in the most accurate information regarding the rockfish populous along the California Coast. What an outstanding collection of photos and hard data regarding these species of fish. Our hats off to these 'extreme' scientists who braved the offshore weather to bring us such an information-packed resource. The high-resolution photos of these fish in their natural habitat are amazing, as well as the high-tech methods of capturing these photos through remotely operated vehicles and submersibles. Well done!"--Ken Franke, Sportfishing Association of California "This guide represents a tremendous amount of excellent work stemming from new technology developed to assess the status of species inhabiting rocky and high-relief habitats. Optically assisted acoustics is the future of fishery stock assessments, and rockfish sustainability depends on the kind of visual observations that this book presents."--Bill Fox, World Wildlife Fund "Via submersible technology, excellent photographic contributions, and vast and caring knowledge, John Butler, Milton Love, and Thomas Laidig have brought this wonderful group of fishes to life. Sebastophiles rejoice--a magnificent resource has arrived!"--Andy Lamb, co-author of Coastal Fishes of the Pacific Northwest and Marine Life of the Pacific Northwest "Although rockfishes are an ecologically, economically, and culturally important group, there has not been a guidebook dedicated to their many species and relatives. This excellent volume not only describes the adults but also the commonly seen juveniles, and the superb pictures and detailed descriptions differentiate similar-looking species. A Guide to the Rockfishes, Thornyheads, and Scorpionfishes of the Northeast Pacific will prove invaluable to keen observers of the underwater world, scientists and casual observers alike."--Jan Freiwald, Reef Check California

Available in PDF, EPUB and Kindle. Book excerpt: New Natures broadens the dialogue between the disciplines of science and technology studies (STS) and environmental history in hopes of deepening and even transforming understandings of human-nature interactions. The volume presents richly developed historical studies that explicitly engage with key STS theories, offering models for how these theories can help crystallize central lessons from empirical histories, facilitate comparative analysis, and provide a language for complicated historical phenomena. Overall, the collection exemplifies the fruitfulness of cross-disciplinary thinking. The chapters follow three central themes: ways of knowing, or how knowledge is produced and how this mediates our understanding of the environment; constructions of environmental expertise, showing how expertise is evaluated according to categories, categorization, hierarchies, and the power afforded to expertise; and lastly, an analysis of networks, mobilities, and boundaries, demonstrating how knowledge is both diffused and constrained and what this means for humans and the environment. Contributors explore these themes by discussing a wide array of topics, including farming, forestry, indigenous land management, ecological science, pollution, trade, energy, and outer space, among others. The epilogue, by the eminent environmental historian Sverker Sorlin, views the deep entanglements of humans and nature in contemporary urbanity and argues we should preserve this relationship in the future. Additionally, the volume looks to extend the valuable conversation between STS and environmental history to wider communities that include policy makers and other stakeholders, as many of the issues raised can inform future courses of action.

Available in PDF, EPUB and Kindle. Book excerpt: Upwelling systems are special places in the oceans where nutrient-enriched water is brought into the euphotic zone to fuel phytoplankton blooms that, via marine food-web interactions, create the world’s richest fish resources. This book introduces the reader to the interdisciplinary science of upwelling and provides a comprehensive overview of the world’s most productive marine ecosystems in the context of climate variability, climate change and human exploitation. This material presented is suitable for undergraduate and postgraduate study or just for anyone interested to learn about the creation of life in the oceans and how this is compromised by human activities.

Available in PDF, EPUB and Kindle. Book excerpt: Not far from Seattle skyscrapers live 150-year-old clams, more than 250 species of fish, and underwater kelp forests as complex as any terrestrial ecosystem. For millennia, vibrant Coast Salish communities have lived beside these waters dense with nutrient-rich foods, with cultures intertwined through exchanges across the waterways. Transformed by settlement and resource extraction, Puget Sound and its future health now depend on a better understanding of the region’s ecological complexities. Focusing on the area south of Port Townsend and between the Cascade and Olympic mountains, Williams uncovers human and natural histories in, on, and around the Sound. In conversations with archaeologists, biologists, and tribal authorities, Williams traces how generations of humans have interacted with such species as geoducks, salmon, orcas, rockfish, and herring. He sheds light on how warfare shaped development and how people have moved across this maritime highway, in canoes, the mosquito fleet, and today’s ferry system. The book also takes an unflinching look at how the Sound’s ecosystems have suffered from human behavior, including pollution, habitat destruction, and the effects of climate change. Witty, graceful, and deeply informed, Homewaters weaves history and science into a fascinating and hopeful narrative, one that will introduce newcomers to the astonishing life that inhabits the Sound and offers longtime residents new insight into and appreciation of the waters they call home.
