Book Description
The threat of deteriorating habitats and a loss of biodiversity make this reference work on the freshwater fishes of British Columbia more necessary than ever before. Eighty-one comprehensive species accounts aid accurate identification and consist of an illustration, the scientific and common names of the fish, its distinguishing characteristics, taxonomic comments, geographic distribution, a life-history summary, a habitat-use summary, and conservation comments. The book is a critical resource for biologists, naturalists, management and conservation officers, anglers, and members of the public who are concerned about our natural heritage.

Book Description
Anders Halverson provides an exhaustively researched and grippingly rendered account of the rainbow trout and why it has become the most commonly stocked and controversial freshwater fish in the United States. Discovered in the remote waters of northern California, rainbow trout have been artificially propagated and distributed for more than 130 years by government officials eager to present Americans with an opportunity to get back to nature by going fishing. Proudly dubbed an entirely synthetic fish by fisheries managers, the rainbow trout has been introduced into every state and province in the United States and Canada and to every continent except Antarctica, often with devastating effects on the native fauna. Halverson examines the paradoxes and reveals a range of characters, from nineteenth-century boosters who believed rainbows could be the saviors of democracy to twenty-first-century biologists who now seek to eradicate them from waters around the globe. Ultimately, the story of the rainbow trout is the story of our relationship with the natural world--how it has changed and how it startlingly has not.

Book Description
The Forest Practices Code guidebooks help forest resource managers plan, prescribe and implement sound forest practices that comply with the Forest Practices Code. This guidebook is designed to be a "fine filter" approach to addressing habitat requirements of critical wildlife, in addition to the "coarse filter" approach provided by the Biodiversity Guidebook and the Riparian Management Area Guidebook.

Book Description
This beautiful and definitive guide brings together the world's lead leading expert on North American trout and salmon, Robert Behnke, and the foremost illustrator in the field, Joseph Tomelleri. North America is graced with the greatest diversity of trout and salmon on earth. From tiny brook trout in mountain streams of the Northeast, to cutthroat trout in the rivers of the Rockies, to Chinook salmon of the Pacific, the continent is home to more than 70 types of trout and salmon. How this came to be, how they are related, and what makes them unique -- and so breathtaking -- is the story of Trout and Salmon of North America. The more than 100 illustrations of trout and salmon by Joseph Tomelleri showcased here exhibit a genius for detail, coloration, and proportion. Each portrait is made from field notes, streamside observations, photographs, and specimens collected by the artist. The result is a set of the most accurate and stunning illustrations of fish ever created. Robert Behnke has distilled 50 years of his research and writing about trout and salmon in completing this book. No one understands better than Behnke the diversity and conservation issues concerning these fishes or communicates so lucidly the biological wonders and complexities of their particular beauty. Also included are more than 40 richly detailed maps that clearly show the ranges of populations of trout and salmon throughout North America. An irresistible delight for anyone who appreciates natural history, Trout and Salmon of North America is a master guide to the natural elegance of our native fishes.

Book Description
Safe Passages brings together in a single volume the latest information on the emerging science of road ecology as it relates to mitigating interactions between roads and wildlife. This practical handbook of tools and examples is designed to assist individuals and organizations thinking about or working toward reducing road-wildlife impacts. The book provides: an overview of the importance of habitat connectivity with regard to roads current planning approaches and technologies for mitigating the impacts of highways on both terrestrial and aquatic species different facets of public participation in highway-wildlife connectivity mitigation projects case studies from partnerships across North America that highlight successful on-the-ground implementation of ecological and engineering solutions recent innovative highway-wildlife mitigation developments Detailed case studies span a range of scales, from site-specific wildlife crossing structures, to statewide planning for habitat connectivity, to national legislation. Contributors explore the cooperative efforts that are emerging as a result of diverse organizations—including transportation agencies, land and wildlife management agencies, and nongovernmental organizations—finding common ground to tackle important road ecology issues and problems. Safe Passages is an important new resource for local-, state-, and national-level managers and policymakers working on road-wildlife issues, and will appeal to a broad audience including scientists, agency personnel, planners, land managers, transportation consultants, students, conservation organizations, policymakers, and citizens engaged in road-wildlife mitigation projects.

Book Description
Cutthroat tells the full story of the genuine native trout of the American West. This new edition, thoroughly revised and updated after 20 years, synthesizes what is currently known about one of our most interesting and colorful fishes, includes much new information on its biology and ecology, asks how it has fared in the last century, and looks toward its future. In a passionate and accessibly written narrative, Patrick Trotter, fly fisher, environmental advocate, and science consultant, details the evolution, natural history, and conservation of each of the cutthroat's races and incorporates more personal reflections on the ecology and environmental history of the West's river ecosystems. The bibliography now includes what may be the most comprehensive and complete set of references available anywhere on the cutthroat trout. Written for anglers, nature lovers, environmentalists, and students, and featuring vibrant original illustrations by Joseph Tomelleri, this is an essential reference for anyone who wants to learn more about this remarkable, beautiful, and fragile western native.

Book Description
The Zoogeography of North American Freshwater Fishes is a timely, authoritative monograph which serves a twofold purpose. First, it discusses the distribution of North American freshwater fish throughout the continent. It then attempts to explain these observed distribution patterns and develops a theory for the dispersal and evolution of these fishes through historical drainage alterations, plate tectonics, and Pleistoscene glaciation. The Zoogeography of North American Freshwater Fishes is a comprehensive treatment of the freshwater biogeography of North America, with implications for other disciplines. It stresses the intimate relationship between geological changes in the landscape on fish dispersal and evolution. For biologists, geologists, and geographers actively involved in biogeography, this book serves as a valuable-and practical-reference.
