For several years we have been exploring how microbial responses to multiple global changes fluctuate over time, space, and in relation to local adaptation and natural disturbance.
Specific Projects:
- How microbial growth, carbon use (using δ13C signatures), and sulfur cycling respond to warming and elevated CO2 in a southern boreal peat bog at the SPRUCE experiment. This experiment takes place at the Marcell experimental forest in northern Minnesota. This work is occurring in collaboration with Randy Kolka and Stephen Sebestyen at the US Forest Service Northern Research Station and Brandy Toner and Ed Nater in the UMN Department of Soil, Water, and Climate.
- We are also finalizing work to better understand the role of microbial communities in ecosystem responses to global change by investigating microbial responses to wildfire disturbance and multiple global changes at the Jasper Ridge Global Change Experiment.
