B23C:
Microbial Controls of Biogeochemical Cycling III Posters


Session ID#: 10334

Session Description:
Microbial communities control nutrient transformation and storage in ecosystems. More explicit treatment of microbial processes in large-scale predictive models is needed, and elucidating these processes requires a unified approach. Biogeochemical approaches may focus on process, pools, and fluxes while microbial approaches may focus on individual or community traits, physiology, and community structure. These approaches are complementary. Physical and chemical properties of soil provide niche space for microorganisms and influence community resilience to local disturbances and regional climatic shifts. Specific assemblages of microbes can differentially influence rates of nutrient cycling, and physiological acclimation to environmental change is likely. Molecular, genomic, and metabolomic tools are improving understanding of microbial processes that control biogeochemical cycling in soils. This session invites studies that investigate microbial populations, communities and microbial-mediated processes controlling carbon and nutrient cycling, feedbacks on plant communities, and effects on ecosystem function.
