Managing Global Resources for a Secure Future

2017 Annual Meeting | Oct. 22-25 | Tampa, FL

207 Symposium--New Insights on Biogeochemical Processes in Terrestrial Ecosystems As Revealed By Isotopic and Biomarker Approaches I

Oral Session
SSSA Division: Forest, Range and Wildland Soils
The measurement of stable isotopes and use of biomarkers has been widely applied to environmental research questions over the past few decades and continue to provide notable scientific advances on issues related to soil biogeochemistry.   A key aspect of isotopic and biomarker research is the ability to non-destructively study complex interactions among soils, plants and the atmosphere, integrating abiotic and biotic processes occurring at different spatial and temporal scales. In this symposium/session, we invite speakers to present on recent theoretical and experimental developments in soil biogeochemical processes as revealed by isotopic and biomarker analysis.
