Book Inland Fishes of the Greater Southwest

Download or read book Inland Fishes of the Greater Southwest written by W. L. Minckley and published by University of Arizona Press. This book was released on 2009 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive new book replaces and substantially expands upon the landmark Fishes of Arizona, which has been the authoritative source since it was first published in 1973. Inland Fishes of the Greater Southwest is a one-volume guide to native and non-native fishes of the lower Colorado River basin, downstream from the Grand Canyon, and of the northern tributaries of the Sea of Cortez in the United States and Mexico. In all, there are in-depth accounts of more than 165 species representing 30 families. The book is not limited to the fish. It provides insights into their aquatic world with information on topography, drainage relations, climate, geology, vegetational history, aquatic habitats, human-made water systems, and conservation. A section of the book is devoted to fish identification, with keys to native and non-native families as well as family keys to species. The book is illustrated with more than 120 black-and-white illustrations, 47 full-color plates of native fishes, and nearly 40 maps and figures. Many native fish species are unique to the Southwest. They possess interesting and unusual adaptations to the challenges of the region, able to survive silt-laden floods as well as extreme water temperatures and highly fluctuating water flows ranging from very low levels to flash floods. However, in spite of being well-adapted, many of the fish described here are threatened or endangered, often due to the acts of humans who have altered the natural habitat. For that reason, Inland Fishes of the Greater Southwest presents a vast amount of information about the ecological relationships between the fishes it describes and their environments, paying particular attention to the ways in which human interactions have modified aquatic ecosystemsÑand to how humans might work to ensure the survival of rapidly disappearing native species.

Book Lost a Desert River and Its Native Fishes

Download or read book Lost a Desert River and Its Native Fishes written by Gordon Mueller and published by . This book was released on 2002 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Colorado River had one of the most unique fish communities in the world. Seventy-five percent of those species were found nowhere else in the world. Settlement of the lower basin brought dramatic change to both the river and its native fish. Those changes began more than 120 years ago as settlers began stocking nonnative fishes. By 1930, nonnative fish had spread throughout the lower basin and replaced native communities. All resemblance of historic river conditions faded with the construction of Hoover Dam in 1935 and other large water development projects. Today, few remember what the Colorado River was really like. Seven of the nine mainstream fishes are now Federally-protected as endangered. Federal and state agencies are attempting to recover these fish. However, progress has been frustrated due to the severity of human impact. This report represents testimony, old descriptions, and photographs describing the changes that have taken place in hopes that it will provide managers, biologists, and the interested public a better appreciation of the environment that shaped these unique fish.

Book Annotated Bibliography for Aquatic Resource Management of the Upper Colorado River Ecosystem

Download or read book Annotated Bibliography for Aquatic Resource Management of the Upper Colorado River Ecosystem written by and published by . This book was released on 1980 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of water and other natural resources in the Upper Colorado River Basin will continue to have an impact on the ecology of this unique ecosystem. Numerous water-development projects have been completed on the river, others are in progress, and still others are contemplated, to provide water necessary for municipalities, irrigated agriculture, and energy production. Although much information is already available on this river, it is widely scattered in the published literature and unpublished reports of various state and federal agencies. This annotated bibliography contains 1,109 published or readily available unpublished references that should be useful in decisions regarding effective management of the Upper Colorado River Basin. Selected key words were assigned to all references and indexed for ease of locating references on particular subjects.
