Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.

Download or read book Inshore Fisheries Management written by David Symes and published by Springer Science & Business Media. This book was released on 2001-12-31 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite their importance in terms of employment and income generation, inshore fisheries have been a neglected area of study. The review of the common fisheries policy, especially in the light of the need to re-examine the derogation which reserves access to the inshore zone to coastal state vessels, provides an opportunity to redress the balance. With contributions from leading authorities on fisheries management, the book takes an in-depth look at seven European countries, examining the basis for the definition of inshore fisheries, evaluating their status, and describing the salient characteristics of their management. The national studies form the basis for cross-cultural analyses of the social organisation, cultural norms, economic objectives, and institutional structures of inshore fisheries in Europe. Finally, a number of key issues relating to the future of inshore fisheries management in a more integrated approach are examined. Overall the volume reaffirms the invaluable role played by inshore fisheries in the local and regional economies of Europe's complex coastline.

Download or read book Sharks and Their Relatives written by Merry Camhi and published by IUCN. This book was released on 1998 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sharks and their relatives, the rays and chimaeras, are the diverse group of cartilaginous fishes that have evolved over 400 million years. Historically considered of low economic value to large-scale fisheries, today many of these fishes have become the target of directed commercial and recreational fisheries around the world, and they are increasingly taken in the by-catch of fisheries targeting other species. This report emphasizes the widely-acknowledged need to improve shark fishery monitoring, expand biological research and take management action. It serves as an introduction to the ecology, status and conservation of the sharks and their relatives for a general audience. Shark fisheries can only be managed sustainably, and shark populations remain viable, with the introduction of new conservation and management initiatives.
