Microbes in Terrestrial Biogeochemical Cycles: Linking Processes to Ecosystem Function and Environmental Change

Session ID#: 75984

Session Description:
Microbes play critical roles regulating terrestrial biogeochemical cycles. Integrating our understanding of microbial dynamics and soil physical and chemical properties is a global research priority. Studies that integrate biogeochemical measurements and microbial ecological approaches examining community level physiology, traits and interactions reveal the ecological complexities that influence terrestrial ecosystem responses. How do individual microbial traits influence community stability and response to disturbances? How do community interactions, including viral predation, influence soil nutrient storage and transformation? How do gradients in reduction-oxidation potential over varied spatiotemporal scales dictate nutrient pools and fluxes? How can we use this information to predict large-scale fluctuations in soil carbon and nutrient storage? Advances in genomic-based techniques, high-resolution geochemical profiling, and in characterization of soil physical structure are improving our understanding of how microbial processes influence ecosystems. We invite cross-disciplinary studies that investigate microbial-driven responses along environmental gradients, to disturbance, and/or in the context of climate change.
