the landscape features, glacial history, and floodplain evolution of the Val Roseg. This is followed by chapters on channel typology, groundwater-surfacewater interactions, thermal heterogeneity, and nutrient dynamics. Chapters on the biota deal with terrestrial and aquatic flora, hyphomycete fungi, surface zoobenthos, and the interstitial fauna. Functional processes are addressed in chapters on organic matter dynamics, litter decomposition, nutrient limitation, and drift and colonization patterns. The final chapter provides a synthesis of our current understanding of the ecology of Val Roseg. Weare indebted to many individuals and organizations for assistance and support of the research program on the Val Roseg and the production of this book.
