With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution.

Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts.

Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

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 ecosystems—and to how humans might work to ensure the survival of rapidly disappearing native species.

America’s western rivers are under assault from development, pollution, invasive species, and climate change. Returning these eco- systems to the time of European contact is often the stated goal for restoration efforts, yet neither the influence of indigenous societ- ies on rivers at the time of contact nor the deeper evolutionary relationships are yet understood by the scientific world. This volume presents a unique synthesis of scientific discoveries and traditional knowledge about the ecology of iconic river species in the American West.

Building from a foundation in fisheries biology and life history data about key species, the book reveals ancient human relationships with those species and describes time-tested Native resource management techniques, drawing from the archaeological record and original ethnographic sources. It evaluates current research trends, summarizes the conceptual foundations for the cultural and evolutionary significance of sustainable use of fish, and seeks pathways for future research. Geographic areas described include the Columbia Plateau, Idaho’s Snake River Plain, the Sacramento River Delta, and the mid-Fraser River of British Columbia. Previously unpublished information is included with the express permission and approval of tribal communities. This approach broadens and deepens the available body of data and establishes a basis for future collaboration between scientists and Native stakeholders toward mutual goals of river ecosystem health.
