Dr. Groffman's research focuses on microbial processes in an ecosystem context. His objectives are to gain insight into 1) the role that microorganisms play in ecosystem functions related to nutrient cycling, water and air quality and soil carbon storage and 2) environmental regulation of microbes. Developing conceptual and practical ecosystem contexts for this work has required a large number of study sites and strong collaborations with other scientists.
Earthworms effect microbial nitrogen cycling and ecosystem nitrogen retention. Earthworm invasion of north temperate forests will have large consequences for nutrient retention and uptake in these ecosystems.
In the northern hardwood forests in New Hampshire we are analyzing how soil freezing events cause root and microbial mortality, which can lead to increased rates of N and P mineralization and loss.
The Cary Institute has taken a lead role in developing a program aimed at understanding urban ecosystems, one of Earth's fastest growing environments.
We are analyzing how changes in soil base status can influence microbial physiology, organic matter quality, and microbial activity in northern hardwood forests at Hubbard Brook.
A result of urban land use change is homogenization across cities, where neighborhoods in very different parts of the country have similar patterns of roads and other features. Understanding urban homogenization will provide the basis for understanding the impacts of urban land use change from local to continental scales.
