Conclusion -- 26. Future research directions in forest hydrology and biogeochemistry. This international rigorously peer-reviewed volume critically synthesizes current knowledge in forest hydrology and biogeochemistry. It is a one-stop comprehensive reference tool for researchers and practitioners in the fields of hydrology, biogeoscience, ecology, forestry, boundary-layer meteorology, and geography. Following an introductory chapter tracing the historical roots of the subject, the book is divided into the following main sections: - Sampling and Novel Approaches - Forest Hydrology and Biogeochemistry by Ecoregion and Forest Type - Hydrologic and Biogeochemical Fluxes from the Canopy to the Phreatic Surface - Hydrologic and Biogeochemical Fluxes in Forest Ecosystems: Effects of Time, Stressors, and Humans The volume concludes with a final chapter that reflects on the current state of knowledge and identifies some areas in need of further research.
