After a short introduction (five pages), the first 17 pages of Chapter 2 provide background on topography, as well as geologic, climatologic, and vegetation history relevant to ecology and evolution of the natural aquatic ecosystems of a much broader region—all major North American deserts. The next 24 pages are an overview of the extensive recent human alterations of aquatic systems in the hydrologically defined focal area. Conservation issues are mentioned in Chapter 2, but Chapter 3 focuses on that and although short (4.5 pages), it is anything but sweet, strongly criticizing the political system and management agencies for failure to apply sound science and allowing the long, continual decline of native fishes to go unchecked. Chapter 4 (203 pages) contains brief guides to anatomy and identification, family and species keys, and very well-done, comprehensive species accounts for 173 species (75 native, including four undescribed). Content covering northwest Mexico is noticeably lighter than for Arizona. All species ever recorded are included, whether or not they have self-sustaining populations.A very strong point is the book's comprehensive (72 pages) Literature Cited section, including substantial “gray” literature that previously had been underutilized and hard to find. I would have liked to have seen more citation of “raw” data (e.g., museum catalog numbers for key records) and was a bit surprised to see illustrations ranging from many very simple line drawings (little more than outlines) through occasional black-and-white photographs, but there are also many higher quality line drawings with greater detail and 47 nice color plate illustrations. Dot and shaded maps are provided for native species only. I found very few errors, all minor, and overall found this to be an authoritative and valuable contribution on this important and very much imperiled fauna and the complex issues that imperil it."
