​We invite you to submit your abstract to:

B083: The Role of Microbes in Terrestrial Biogeochemical Cycles: Linking Responses to Ecosystem Processes and Environmental Change

Early deadline July 25th / final deadline August 1st. 

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.

Dawson Fairbanks

That is one of the questions our CZO is exploring after the successful completion of a deep drilling expedition in northern New Mexico (picture at bottom). We are just beginning to discover how deep the surface single extends into the critical zone, the life-giving region on terrestrial earth that ranges from the bottom of aquifers to the tops of trees. These subsurface regions are extremely oligotrophic, meaning they are limited in nutrient and energy inputs. However, microbial life does exist here, and we are using special protocols to extract DNA from rock cores collected from these sensitive deep subsurface samples. 

Dawson returned a month ago from a successful training visit as part of the CZO SAVI International Scholars award to visit Kirsten Küsel's geomicrobiology group in Jena Germany. There she learned about how to process and extract DNA from core samples using protocols developed in their lab, allowing better cross-comparisons between sites. The goal was to limit contamination of samples and to successfully obtain DNA from these extremely low DNA environments.

Dawson also gave a talk discussing some of the exciting wildfire research our CZO has been doing, further fostering international exchange of research ideas. She also visited the Max Planck Institute for Biogeochemistry learning about some of the exciting research being conducted there exploring deep subsurface carbon cycling using stable isotopes. She also participated in a 4 day field expedition learning techniques to sample water from deep aquifers. A huge thank you to the host institute and looking forward to future interactions, exchange, and research collaborations.
