Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Feeding Ecology of Fish establishes a comprehensive framework for the variable ecological patterns exemplified by feeding fishes. The author, a former president of the American Fisheries Society, devotes special attention to synthesizing empirical studies in categorizing feeding patterns. This book shows how remarkably adaptable fish can be with regard to selecting food, often from trophic levels not usually occupied. Relying on a thorough literature survey, Feeding Ecology of Fish will be an invaluable reference for both fishery scientists and ecological theorists. - Organization by trophic level - Emphasis on empirical studies - Broad coverage of a diverse field

Download or read book River Ecology and Management written by Robert Naiman and published by Springer Science & Business Media. This book was released on 2001-02-16 with total page 734 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the vast expanses of natural forests and the great populations of salmonids are harvested to support a rapidly expanding human population, the need to understand streams as ecological systems and to manage them effectively becomes increasingly urgent. The unfortunate legacy of such natural resource exploitation is well documented. For several decades the Pacific coastal ecoregion of North America has served as a natural laboratory for scientific and managerial advancements in stream ecology, and much has been learned about how to better integrate ecological processes and characteristics with a human-dominated environment. These in sightful but hard-learned ecological and social lessons are the subject of this book. Integrating land and rivers as interactive components of ecosystems and watersheds has provided the ecological sciences with impor tant theoretical foundations. Even though scientific disciplines have begun to integrate land-based processes with streams and rivers, the institutions and processes charged with managing these systems have not done so successfully. As a result, many of the watersheds of the Pacific coastal ecoregion no longer support natural settings for environmental processes or the valuable natural resources those processes create. An important role for scientists, educators, and decision makers is to make the integration between ecology and con sumptive uses more widely understood, as well as useful for effective management.

Download or read book Watershed Management written by Robert J. Naiman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 738 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conceptual separation of humans and natural ecosystems is reflected in the thinking of most natural resource management professions, including for estry, wildlife management, fisheries, range management, and watershed management (Burch 1971). Such thinking can deny the reality of the human element in local, regional, and global ecosystems (Bonnicksen and Lee 1982, Klausner 1971, Vayda 1977). As complex organisms with highly developed cultural abilities to modify their environment, humans directly or indirectly affect almost all terrestrial and aquatic ecosystems (Bennett 1976). Conse quently, information for managing watershed ecosystems is incomplete without consideration of human institutions and activities. Sociologists have studied the relationships between human societies and the land base or ecosystems on which they depend for over 60 years (Field and Burch 1990). These studies are distinguished by (1) a holistic perspec tive that sees people and their environments as interacting systems, (2) flex ible approaches that permit either the environment or human society to be treated as the independent variable in analyzing of society-environment re lations, and (3) accumulation of a substantial body of knowledge about how the future welfare of a society is influenced by its uses (or misuses) of land and water (Firey 1990).

Download or read book Owning It All written by William Kittredge and published by . This book was released on 2002 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a deeply felt and highly informed essay collection about life in the American west by one of the finest writers ever to emerge from that region. As the Seattle Times has said of Owning It All: "You may never again see the American west in quite the same way if you take the time to view it through the eyes of William Kittredge. [This is a] stunning book." Having grown up on his family's cattle ranch in eastern Oregon, Kittredge directly confronts the contradictions and myths that lie at the heart of the Western experience: male freedom and female domesticity, the wild and the tame, self-interest and love of the land.
