Elucidating Coupled Biogeochemical Cycles in Terrestrial Ecosystems: Integrating Theory, Observations, Experiments, and Models
Session ID#: 75817
Session Description:
Nutrients (nitrogen, phosphorus and others) have the potential to mediate plant growth and ecosystem carbon balance in response to environmental change. Despite a range of data suggesting nutrient constraints on terrestrial ecosystems, we have a poor understanding of how nutrient cycling may respond to environmental perturbations like elevated CO2, warming, and changes in the hydrologic cycle. Moreover, our inability to simulate nutrient effects on the global carbon cycle undermine efforts to accurately project carbon cycle-climate feedbacks in a changing world. At the same time, only a handful of current models even attempt to represent those interactions and feedbacks. This session aims to identify gaps in understanding and representation of modeled carbon-nutrient interactions and discuss experiments, manipulations, syntheses, and simulations that will increase our ability to predict if and how nutrients may constrain the global terrestrial carbon cycle into the future.
