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 StatesThe 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.
