Professor Peter Groffman of ASRC, Brooklyn College, and EES has first-authored a paper in Biogeochemistry entitled “ Nitrogen oligotrophication in northern hardwood forests”.   Abstract: While much research over the past 30 years has focused on the deleterious effects of excess N on forests and associated aquatic ecosystems, recent declines in atmospheric N deposition and unexplained declines in N export from these ecosystems have raised new concerns about N oligotrophication, limitations of forest productivity, and the capacity for forests to respond dynamically to disturbance and environmental change. Here we show multiple data streams from long-term ecological research at the Hubbard Brook Experimental Forest …
