Microbial Community Assembly and Feedbacks on Biogeochemical Cycling:
ISU Barton Road Ecological Research Site. Cheatgrass invasion of Sagebrush Steppe alters belowground fungal and bacterial assemblages as well as soil-atmosphere trace gas fluxes.
We work at both organismal and landscape scales to understand the basic principles of plant-associated microbial community assembly, how this is impacted by environmental disturbances (e.g. invasive plant species (left), changing nutrient regimes) and the resulting feedbacks on biogeochemical cycling.
