B42D:
The Role of Microbes in Terrestrial Biogeochemical Cycles: Linking Responses to Ecosystem Processes and Environmental Change I


Submit an Abstract to this Session


Session ID#: 59963

Session Description:
Microbes play critical roles regulating terrestrial biogeochemical cycles. Linking processes controlling nutrient transformation and storage with disturbance responses and feedbacks to climate change is a global research priority. Studies that integrate biogeochemical approaches focused on nutrient pools and fluxes with microbial ecology approaches examining community physiology, traits, and structure reveal the complexity of interactions influencing ecosystem responses. How do individual microbial traits influence community stability and response to disturbances? How does microbial community structure change across gradients and influence vegetation dynamics? How can we use this information to predict large-scale fluctuations in soil carbon and nutrient storage? Although advances in molecular and genetic tools are improving our understanding of how microbial processes influence ecosystems, questions surrounding the level of detail appropriate to best predict environmental response to change remain. We invite cross-disciplinary studies that investigate microbial-driven responses along environmental gradients, to disturbance, and/or in the context of climate change.
