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.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2017-08-11 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
Download or read book Lake and Reservoir Restoration written by G. Dennis Cooke and published by Elsevier. This book was released on 2013-10-22 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake and Reservoir Restoration deals with the eutrophication process and the methods to protect, restore, and manage lakes and reservoirs. The most common in-lake techniques or procedures, plus nutrient diversion, are reviewed with regard to their scientific basis, methods of application, known effectiveness, feasibility, drawbacks, and costs. Areas for further research and development are also highlighted. This book is comprised of 16 chapters organized into four sections. After an introduction to the theory of the problem and the restoration technique, the discussion turns to the various restoration methods such as those used for physical and chemical control of nutrients. Diversion and advanced waste treatment, hypolimnetic withdrawal, and dilution and flushing are considered along with phosphorus precipitation and inactivation, sediment oxidation, sediment removal, and hypolimnetic aeration. Case studies and success stories are presented and the costs and potential negative impacts of the methods are examined. The following chapters focus on methods to control plant biomass, including artificial circulation, water-level drawdown, harvesting, biological control, and surface and sediment covers. A chapter on liming acidified lakes concludes this text. This monograph will be useful to professional limnologists and engineers, on-site lake or reservoir managers, and those who are interested in learning about the problems and management of lakes and reservoirs.
