We welcome contributions on the quantification and interpretation of carbon, water, and nutrient cycles, and their interactions. Topics to be addressed at different spatio-temporal scales may include among others: drought and wetness effects on the carbon and nitrogen cycles, regional to global quantification of carbon and water cycles, water-use efficiency, biogeochemical cycle feedbacks to the water cycle, and the role of vegetation dynamics in carbon, water and nutrient cycles. Analyses using AmeriFlux or FLUXNET data are welcome, but we are also interested in both smaller and larger spatial scales and levels of integration. We encourage modeling, experimental and monitoring studies, particularly those that focus on testing hypotheses, isolating mechanisms and processes, and identifying knowledge gaps
