Session Description:
Microbes play a critical role in regulating biogeochemical cycles. How these processes respond and feedback to climate change and disturbance is widely debated. Biogeochemical methods focus on nutrient pools and fluxes while microbial ecological advances focus on community physiology, traits and structure. A cross-disciplinary approach is integral to understanding how to include microbe-mediated processes in large-scale ecosystem models. How do individual microbial traits influence community stability and response to disturbances? How does microbial community structure change across gradients and influence plant dynamics? How can we use this information to predict large-scale fluctuations in soil carbon and nutrient storage? Advances in molecular and genetic methods inform understanding of how microbial processes influence ecosystem scale cycles, and create questions about the level of detail appropriate to best predict environmental response to change. This session invites cross-disciplinary studies that investigate microbial-driven responses to disturbance, climate change and across environmental gradients.
