Gene Likens

Gene Elden Likens (born January 6, 1935) is an American limnologist and ecologist. He co-founded the Hubbard Brook Ecosystem Study at the Hubbard Brook Experimental Forest in 1963, and founded the Cary Institute of Ecosystem Studies in Millbrook, New York in 1983. A leading pioneer in long-term multidisciplinary ecological studies, Likens examines energy flow and biogeochemical flux models in the ecosystems of forests, streams and lakes. Likens is best known for leading the team of scientists that discovered acid rain in North America, and connected fossil fuels with increasing acidity of precipitation. In addition to its scientific impact, this work has influenced public debate and governmental policy, particularly the United States Congress's Clean Air Act Amendments of 1990.
