Available in PDF, EPUB and Kindle. Book excerpt: Written as a stand-alone textbook for students and a useful reference for professionals in government and private agencies, academic institutions, and consultants, Ecology and Conservation of Fishes provides broad, comprehensive, and systematic coverage of all aquatic systems from the mountains to the oceans. The book begins with overview discussions on the ecology, evolution, and diversity of fishes. It moves on to address freshwater, estuarine, and marine ecosystems and identifies factors that affect the distribution and abundance of fishes. It then examines the adaptations of fishes as a response to constraints posed in ecosystems. The book concludes with four chapters on applied ecology to discuss the critical issues of management, conservation, biodiversity crises, and climate change. Major marine fisheries have collapsed, and there are worldwide declines in freshwater fish populations. Fishery scientists and managers must become more effective at understanding and dealing with resource issues. If not, fish species, communities, and entire ecosystems will continue to decline as habitats change and species are lost. Ecology and Conservation of Fishes has taken a historical and functional approach to explain how we got where we are, providing old and new with a better foundation as ecologists and conservationists, and most importantly, it awakens senses of purpose and need. Past management practices are reviewed, present programs considered, and the need for incorporating principles of applied ecology in future practices is emphasized.

Available in PDF, EPUB and Kindle. Book excerpt: "A vivid historical account…Thompson shines in giving a sense of what it means to love a place that's been designated a 'sacrifice zone.'" —PUBLISHERS WEEKLY Award–winning investigative environmental journalist Jonathan P. Thompson digs into the science, politics, and greed behind the 2015 Gold King Mine disaster, and unearths a litany of impacts wrought by a century and a half of mining, energy development, and fracking in southwestern Colorado. Amid these harsh realities, Thompson explores how a new generation is setting out to make amends. JONATHAN THOMPSON is a native Westerner with deep roots in southwestern Colorado. He has been an environmental journalist focusing on the American West since he signed on as reporter and photographer at the Silverton Standard & the Miner newspaper in 1996. He has worked and written for High Country News for over a decade, serving as editor–in–chief from 2007 to 2010. He was a Ted Scripps fellow in environmental journalism at the University of Colorado in Boulder, and in 2016 he was awarded the Society of Environmental Journalists' Outstanding Beat Reporting, Small Market. He currently lives in Bulgaria with his wife Wendy and daughters Lydia and Elena.

Available in PDF, EPUB and Kindle. Book excerpt: This book, the result of a congressionally mandated study, examines the adequacy of the regulatory framework for mining of hardrock mineralsâ€"such as gold, silver, copper, and uraniumâ€"on over 350 million acres of federal lands in the western United States. These lands are managed by two agenciesâ€"the Bureau of Land Management in the Department of the Interior, and the Forest Service in the Department of Agriculture. The committee concludes that the complex network of state and federal laws that regulate hardrock mining on federal lands is generally effective in providing environmental protection, but improvements are needed in the way the laws are implemented and some regulatory gaps need to be addressed. The book makes specific recommendations for improvement, including: The development of an enhanced information management system and a more efficient process to review new mining proposals and issue permits. Changes to regulations that would require all mining operations, other than "casual use" activities that negligibly disturb the environment, to provide financial assurances for eventual site cleanup. Changes to regulations that would require all mining and milling operations (other than casual use) to submit operating plans in advance.
Download or read book Systematics Historical Ecology and North American Freshwater Fishes written by Richard L. Mayden and published by . This book was released on 1992 with total page 969 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book addresses the current need for a holistic approach in comparative and evolutionary biology and offers numerous applications of the modern methods of phylogenetic systematics and historical ecology, using the North American fish fauna as its case study. This major synthesis, the first published work of its kind, provides a theoretical and methodological foundation for future studies in ichthyology, evolutionary biology, and other fields of comparative biology." "Several introductory pieces present major statements of general principles, detailed examinations of the diversity and distributions of North American freshwater fishes, and what is known of their systematic relationships. The rest of the volume's 30 papers then contribute new phylogenetic hypotheses for a significant number of taxa. Along the way, the reader is introduced to the principles, first, of phylogenetic systematics - the reconstruction of evolutionary or ancestor-descendant relationships of groups of organisms on the basis of heritable traits - and, second, of historical ecology - a comprehensive research program that links systematics with many areas of comparative biology. Together, the two allow for the formulation of direct and testable hypotheses regarding the evolution of species and their attributes, interspecies interactions, and the formation and persistence of biotic communities. Without these methods that incorporate "historical controls," our estimates of history for all areas of biology are inefficient, indirect, and worst of all, untestable." "This book focuses on North American freshwater fishes not only because the 42 contributors know them so well but also because this highly diverse fauna is well known in so many important aspects (diversity, species distributions, life histories) relevant to evaluating general applications of the new paradigms of systematics and historical ecology. Many other faunas present interesting biotas appropriate for the preparation of a similar piece of work, but no other fauna can claim as complete a knowledge base." "The theme articulated throughout the book underscores the Darwinian proposition of descent with modification. The biological information particular to the North American freshwater fish fauna establishes an invaluable foundation for understanding diversification and advancing education and research. Moreover, the methods, theories, and empirical data presented serve as essential resources for comparative and evolutionary research programs applicable to any biota or taxonomic grouping." "The book includes some 200 illustrations, 60 tables, 10 appendixes, and comprehensive taxonomic and subject indexes."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Endangered and Threatened Species of the Platte River written by National Research Council and published by National Academies Press. This book was released on 2005-02-24 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.
