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 programs in urban ecology 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.
There is very cool science going on at Hubbard Brook. Scientists from Cary and other research institutions created an experimental ice storm that will improve understanding of short- and long-term effects of ice on northern forests.
Beavers are one of nature's most industrious engineers. Using branches and mud, the intrepid animals create dams that slow moving water. In New York's Hudson Valley, their constructions are a common sight on streams and in wetlands.
Cary's Peter Groffman explores the field of urban ecology and what the striking similarities across urban landscapes mean for the long-term sustainability of metropolitan areas.
Microbial ecologist Peter Groffman consults with NatGeo's David Rees who is looking to design a perfect hole and wants to know what kind of dirt he needs to make it.
Despite their familiarity, earthworms are an invasive species in America's northern temperate forests. They arrived in the mid-1800s, with the arrival of European settlers.
