H41K:
Modeling and Observations of Coupled Biophysical Processes in Terrestrial and Aquatic Environments across Scales I


Session ID#: 10582

Session Description:
The soil physical environment (pore spaces, water distribution, temperature, mechanical properties) plays a dominant role in regulating biological processes and related ecosystem services across scales – from interactions among microbial cells in a pore to the vegetation patterns over the landscape. We invite presentations that address advances in quantification and observation of physical controls on soil biological processes and feedbacks on soil structure and function. Relevant topics include biological activity and diversity across scales, rhizosphere dynamics, biogeochemical cycling, patterns of greenhouse gas fluxes, contaminant bioremediation, consequences of soil warming, biological activity in extreme environments, and biophysical alteration of soil properties. Contributions that are based on field observations and manipulations, laboratory experiments, and modeling are welcome. We are particularly interested in creating a forum for cross-disciplinary exchange of ideas, and thus encourage contributions from diverse communities of soil and critical zone scientists, plant scientists, ecologists, environmental microbiologists, and bioengineers.
