Aquatic Biodiversity: Theories, Approaches, and Future Directions reviews the development of metacommunity ecology theory in aquatic systems. The book explores aquatic dispersal as a driver of community biodiversity, patterns, and processes. Considered a relatively new field, metacommunity ecology created a paradigm shift in the field of aquatic ecology by developing a novel, network-based theory that differences in connectivity throughout aquatic systems lead to predictable variations in the mechanisms of assembly for lentic and lotic communities. This book collates the cutting edge conceptual, theoretical, and empirical advancements of the field and its contributions to invasive species management, biomonitoring, and stream restoration. Written and edited by many of the key researchers contributing to the development of the field, this book is systematically structured for easy accessibility by diverse audiences. Introductory sections discuss the importance of spatial structure, dispersal dynamics in aquatic systems, the effects of disturbances, and eco-evolutionary dynamics. Latter chapters apply these theories by describing field experiments in lentic and lotic systems and highlighting the field's applications to stream restoration, invasive species monitoring, urban ecosystem management, and biomonitoring at varying spatial scales. As advancements and refinements to the field of metacommunity ecology develop, Aquatic Biodiversity presents the first compendium establishing its foundational theories and their applications in aquatic ecology. For this reason, it is an indispensable resource for students, researchers, community ecologists, and aquatic resource managers.

With almost 90% of terrestrial plant material entering the detrital pool, the processing of this significant carbon source is a critical ecosystem function to understand. Riverine ecosystems are estimated to receive, process and transport nearly 1.9 Pg of terrestrial carbon per year globally, highlighting the focus many freshwater ecologists have on the factors that explain decomposition rates of senesced plant material. Since Webster and Benfield offered the first comprehensive review of these factors in 1986, there has been an explosion of research addressing key questions about the ecological interactions at play. Ecologists have developed field and laboratory techniques, as well as created global scale collaborations to disentangle the many drivers involved in the decomposition process. This book encapsulates these 30+ years of research, describing the state of knowledge on the ecology of plant litter decomposition in stream ecosystems in 22 chapters written by internationally renowned experts on the subject.
