While both science and impact assessment rely on technical studies, they differ in fundamental goals, approach and scope, and final products. Research and management biologists come from similar educational backgrounds, share similar career interests, and have a high regard for biological knowledge. However, varied philosophy and interests emerge due to different work settings and responsibilities. Science is defined as systematized knowledge derived from observation, study, and experimentation carried on in order to determine the nature or principles of what is being studied. The basic approach to study is the scientific method: observation, hypothesis formation, hypothesis testing, deriving results, and interpreting findings relative to principle or theories. Impact assessment is the process of documenting the important consequences of proposed actions by (1) objective analyses of current and predicted conditions and (2) subjective evaluation of the significance of predicted changes. In contrast to the scientific method, the impact assessment method uses distinctly different steps: reviewing proposed actions, documenting baseline conditions, identifying possible impacts, predicting changes, documenting significant impacts, and formulating recommendations. The definitions and methods of both science and impact assessment reflect the fundamental differences between these endeavors.

The most comprehensive synthesis of stream fish community research ever produced. Winner of the CHOICE Outstanding Academic Title of the Choice ACRL Ecologists have long struggled to understand community dynamics. In this groundbreaking book, leading fish ecologists William Matthews and Edie Marsh-Matthews apply long-term studies of stream fish communities to several enduring questions. This critical synthesis reaches to the heart of ecological theory, testing concepts against the four decades of data the authors have collected from numerous warm-water stream fish communities in the central and eastern United States. Stream Fish Community Dynamics draws together the work of a single research team to provide fresh analyses of the short- and long-term dynamics of numerous streams, each with multiple sampling sites. Conducting repeated surveys of fish communities at temporal scales from months to decades, the authors' research findings will fascinate anyone searching for a deeper understanding of community ecology. The study sites covered by this book range from small headwater creeks to large prairie rivers in Oklahoma and from Ozark and Ouachita mountain streams in Arkansas to the upland Roanoke River in Virginia. The book includes • A comparison of all global and local communities with respect to community composition at the species and family level, emergent community properties, and the relationship between those emergent properties and the environments of the study sites • Analyses of traits of individual species that are important to their distribution or success in harsh environments • A review of evidence for the importance of interactions—including competition and predation—in community dynamics of stream fishes • An assessment of disturbance effects in fish community dynamics • New analysis of the short- and long-term dynamics of variation in stream fish communities, illustrating the applicability and importance of the "loose equilibrium concept" • New analyses and comparisons of spatiotemporal variation in community dynamics and beta diversity partitioning • An overview of the effects of fish in ecosystems in the central and eastern United States The book ends with a summary chapter that places the authors' findings in broader contexts and describes how the "loose equilibrium concept"—which may be the most appropriate default assumption for dynamics of stream fishes in the changing climate of the future—applies to many kinds of stream fish communities.

Nearly a decade ago I began planning this book with the goal of summarizing the existing body of knowledge on ecology of freshwater fishes in a way similar to that of H. B. N. Hynes' comprehensive treatise Ecology of Running Waters for streams. The time seemed appropriate, as there had been several recent volumes that synthesized much information on a range of topics important in fish ecology, from biogeographic to local scales. For example, the "Fish Atlas" (Lee et aI. , 1980) had provided range maps and basic entry to the original literature for all freshwater fishes in North America, and in 1986 Hocutt and Wiley's Zoogeography of North American Fishes provided a detailed synthesis of virtually everything known about distributional ecology of fishes on that continent. Tim Berra (1981) had summarized in convenient map form the worldwide distribution of all freshwater fish families, and Joe Nelson's 1976 and 1984 editions of Fishes of the World had appeared. To complement these "big picture" views of fish distributions, the volume on Community and Evolutionary Ecology of North American Freshwater Fishes, edited by David Heins and myself (Matthews and Heins, 1987), had provided an opportunity for more than 30 individuals or groups to summarize their work on stream fishes (albeit mostly for warmwater systems).
