Book Synopsis Freshwater Fish Distribution by : Tim M. Berra
Download or read book Freshwater Fish Distribution written by Tim M. Berra and published by University of Chicago Press. This book was released on 2008-09-15 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.
Download or read book Stream Ecology written by J. David Allan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Running waters are enormously diverse, ranging from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents. While this diversity makes river ecosystems seem overwhelmingly complex, a central theme of this volume is that the processes acting in running waters are general, although the settings are often unique. The past two decades have seen major advances in our knowledge of the ecology of streams and rivers. New paradigms have emerged, such as the river continuum and nutrient spiraling. Community ecologists have made impressive advances in documenting the occurrence of species interactions. The importance of physical processes in rivers has attracted increased attention, particularly the areas of hydrology and geomorphology, and the inter-relationships between physical and biological factors have become better understood. And as is true for every area of ecology during the closing years of the twentieth century it has become apparent that the study of streams and rivers cannot be carried out by excluding the role of human activities, nor can we ignore the urgency of the need for conservation. These developments are brought together in Stream Ecology: Structure and function of running waters, designed to serve as a text for advanced undergraduate and graduate students, and as a reference book for specialists in stream ecology and related fields.

Available in PDF, EPUB and Kindle. Book excerpt: The rich tapestry of Alaska is threaded together by 365,000 miles of waterways, from cascading mountain streams to meandering valley rivers, from the meltwaters of glaciers to broad rivers that empty into the sea.

A section on gear outlines what to take into the backcountry.
Book Synopsis Fish Conservation by : Gene S. Helfman
Download or read book Fish Conservation written by Gene S. Helfman and published by Island Press. This book was released on 2007-07-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish Conservation offers, for the first time in a single volume, a readable reference with a global approach to marine and freshwater fish diversity and fishery resource issues. Gene Helfman brings together available knowledge on the decline and restoration of freshwater and marine fishes, providing ecologically sound answers to biodiversity declines as well as to fishery management problems at the subsistence, recreational, and commercial levels. Written in an engaging and accessible style, the book: considers the value of preserving aquatic biodiversity offers an overview of imperiled fishes on a taxonomic and geographic basis presents a synthesis of common characteristics of imperiled fishes and their habitats details anthropogenic causes of decline examines human exploitation issues addresses ethical questions surrounding exploitation of fishes The final chapter integrates topics and evaluates prospects for arresting declines, emphasizing the application of evolutionary and ecological principles in light of projected trends. Throughout, Helfman provides examples, explores case studies, and synthesizes available information from a broad taxonomic, habitat, and geographic range. Fish Conservation summarizes the current state of knowledge about the degradation and restoration of diversity among fishes and the productivity of fishery resources, pointing out areas where progress has been made and where more needs to be done. Solutions focus on the application of ecological knowledge to solving practical problems, recognizing that effective biodiversity conservation depends on meeting human needs through management that focuses on long term sustainability and an ecosystem perspective.

Book Synopsis Freshwater Management by : M. Kumagai
Download or read book Freshwater Management written by M. Kumagai and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The globalization of trade, monetary and fiscal policies, capital markets, and investment patterns is reshaping the world economy and is leading to new financial, commercial, and marketing structures as well as unprecedented economies of scale. Simultaneously, national and international awareness and to strengthen. There is consensus among responses to accelerating environmental degradation continue most developed countries that the rapidly evolving new economic order needs to be well integrated with policies to maintain or restore environmental quality. Many challenges remain, however, in evaluating the geo-ecological implications of economic globalization, and in formulating the appropriate management responses. In lakes and rivers, the management of water supply and quality has largely proceeded on the basis of local considerations rather than at the global scale that has been more typical of environmental management of the atmosphere and ocean. It is increasingly apparent, however, that high-quality water resources are now in critically short supply not only because of local problems such as over-irrigation and eutrophication, but also as a result of larger-scale climate effects on the hydrosphere. This magnitude of impact will increasingly require the integrated monitoring and management of water resources on a planetary scale, with world criteria for environmental assessment, restoration, and conservation strategies. The increasing extent of world trade in potable freshwater heightens the urgency for establishing international approaches, criteria, and regulations.
