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. [1]
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. [1] [2] 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. [3]
Gene Likens was born in Pierceton, Indiana. [4] Likens received his B.S. in zoology at Manchester University (North Manchester, Indiana) in 1957, [5] followed by his M.S. in zoology in 1959 from the University of Wisconsin–Madison. [1] [6] He received his Ph.D. in zoology in 1962, also from the University of Wisconsin–Madison, for his thesis on Transport of radioisotopes in lakes. [7] [8]
Likens was an instructor and associate professor at Dartmouth College from 1963 to 1969. [1] In the 1960s, Likens did early work in the dry valleys of Antarctica, [9] examining the thermal structures of Lake Vanda and Lake Bonney. [7]
Likens was co-founder in 1963 of a group with F. Herbert Bormann, Robert S. Pierce and Noye M. Johnson working on the Hubbard Brook Ecosystem Study at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire. [10] [11] The study immediately found that the rain was abnormally acidic, and the group carried out one of the first scientific studies linking acid rain to air pollution such as sulphur dioxide from the use of fossil fuels. [12] [13]
In 1988, Hubbard Brook was designated by the National Science Foundation as an LTER, a site for collaborative long term ecological research. [3] [11] [14] In 2005, Hubbard Brook celebrated 50 years of research at the site. [11] Likens' work in the area is considered "one of the world’s most comprehensive studies on how air pollution and land use shape forested watersheds". [3] Work at Mirror Lake, at the lower end of the Hubbard Brook Valley, has been particularly important in understanding the importance of physical, chemical, and biological linkages involving the lake and its watershed and airshed. [15] Liken has extensively studied biogeochemical cycles describing the flow of matter within ecosystems. [16] Riparian zones linking water and land are particularly important in maintaining the health of wild lands. [17] Liken has also done important work on deforestation and its potential impact on the chemistry of watersheds. This research has had significant impacts on programs for forest management, in particular the United States Forest Service's adoption of a 100–year rotation policy. [2] [18]
Likens and others devised a range of highly influential long-term experiments on an ecosystemic scale. These include the small-watershed model of nutrient cycling, in which all water entering and leaving a naturally-bounded watershed is measured, enabling scientists to calculate the hydrologic budget of the watershed. [11] This model has been "extremely influential" in the examination of ecosystems, and is central to the examination of urban ecosystems such as Baltimore. [19] Likens' work is considered "classic", [1] [19] and he is credited with establishing a "guiding paradigm" for other ecologists. [1]
In 1969, Likens joined the faculty of Cornell University. He served as an associate professor from 1969 to 1972, and as a full professor from 1972 to 1983. [1] In addition to being a professor of ecology in the Section of Ecology and Systematics (later named the Department of Ecology & Evolutionary Biology), he served as its acting chairman (1973-1974) and chairman (1982-1983). [20] [21] In January 1983 he was named Cornell University's Charles A. Alexander Professor of Biological Sciences. While at Cornell University, he served as chairman of the Section of Ecology and Systematics. [22]
In 1983 Likens founded the (now Cary) Institute of Ecosystem Studies in Millbrook, New York as part of the New York Botanical Garden. In 1993, the IES became an independent non-profit with Likens as director and president. Situated at the Mary Flagler Cary Arboretum, [1] it is an independent center for ecological research, "whose work is highly relevant to policy concerns." [23] In addition to managing teams of scientists and educators, Likens continued his research at Hubbard Brook each summer. [2] As of 2001, he was appointed to the first endowed chair at the Institute of Ecosystem Studies, the G. Evelyn Hutchinson Chair in Ecology. [1]
In 2007 Likens stepped down as director of the IES and returned to full-time research, currently at the University of Connecticut and as visiting professor at the University of Uppsala, Sweden. In July 2012 he began a three-year term as special adviser to the president of the University of Connecticut on environmental affairs and distinguished research professor. [22]
Likens has published 25 books and more than 580 papers and book chapters. [3] Much of his early work is summarized in U.S. Geological Survey publications. [24] His work has influenced the United States Congress on issues such as the Clean Air Act Amendments of 1990. [3]
He has been active in a variety of organizations, and has been the vice-president (1975-1976) and president (1976-1977) of the American Society of Limnology and Oceanography; vice-president (1978-1979), president (1981-1982) and honorary Fellow (2012) of the Ecological Society of America; president (2002) of the American Institute of Biological Sciences; and president (2001-2007) of the International Society of Limnology. [20] [21]
Likens has received a substantial number of awards and honors of various kinds. [20] [21] He was elected to the American Academy of Arts and Sciences in 1979, [6] and the United States National Academy of Sciences in 1981. [1] He was also elected as a foreign member of the Royal Swedish Academy of Sciences in 1988, the Royal Danish Academy of Sciences and Letters in 1994 and the Austrian Academy of Sciences in 2000. [20] He became an elected member in biological sciences of the American Philosophical Society in 2006. [25] He's also a fellow of the American Association for the Advancement of Science. [20]
His awards include the 1988 ECI Prize in Limnetic Ecology, [26] the 1993 Tyler Prize for Environmental Achievement [27] and the 2001 Huxley Medal of the Institute of Biology, London, UK. [6] He received a 2001 National Medal of Science from President George W. Bush on June 13, 2002. [1] In 2003, Likens and Dr. F. Herbert Bormann received the Blue Planet Prize from Asahi Glass Foundation, for "outstanding scientific research that helps to solve global environmental problems". [12] In 2014, he received the Alfred C. Redfield Lifetime Achievement Award from the Association for the Sciences of Limnology and Oceanography (ASLO). [3]
He has been awarded honorary doctoral degrees internationally (Universität für Bodenkultur, Vienna, 1992; Wageningen Agricultural University, The Netherlands, 1998) as well as nationally (Manchester College, 1979; Rutgers University, 1985; Plymouth State College, University System of New Hampshire, 1989; Miami University, 1990; Union College, 1991; Marist College, 1993; University of Connecticut, 2004; Montclair State University, 2012). [21]
He has won the BBVA Foundation Frontiers of Knowledge Award (2016) jointly with Marten Scheffer for contributing decisively to what the jury describes as “one of the major challenges” of this scientific discipline: to understand and, where possible, anticipate ecosystem responses to human-induced alterations of the natural environment.
In 2018 Likens was awarded an honorary doctorate from Uppsala University, Sweden. [28]
Gene Likens and his wife Phyllis Irene Craig Likens (1951–2014) of Clinton Corners, New York have three daughters, Heather, Leslie, and Kathy, and a son, Gregory. Phyllis also worked at Cornell University and the Institute of Ecosystem Studies and contributed significantly to the Hubbard Brook Ecosystem Study. He has seven grandchildren, Sierra, Maxwell, Samuel, Joseph, Noah, Louis, and Jason. [29]
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions. Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. The more acidic the acid rain is, the lower its pH is. Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.
Limnology is the study of inland aquatic ecosystems. The study of limnology includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural and man-made bodies of water. This includes the study of lakes, reservoirs, ponds, rivers, springs, streams, wetlands, and groundwater. Water systems are often categorized as either running (lotic) or standing (lentic).
Hubbard Brook Experimental Forest is an area of land in the towns of Woodstock, Ellsworth and Thornton in the White Mountains of New Hampshire that functions as an outdoor laboratory for ecological studies. It was initially established in 1955 by the United States Forest Service for the study of the relationship between forest cover and water quality and supply.
George Evelyn Hutchinson was a British ecologist sometimes described as the "father of modern ecology." He contributed for more than sixty years to the fields of limnology, systems ecology, radiation ecology, entomology, genetics, biogeochemistry, a mathematical theory of population growth, art history, philosophy, religion, and anthropology. He worked on the passage of phosphorus through lakes, the chemistry and biology of lakes, the theory of interspecific competition, and on insect taxonomy and genetics, zoo-geography, and African water bugs. He is known as one of the first to combine ecology with mathematics. He became an international expert on lakes and wrote the four-volume Treatise on Limnology in 1957.
Patch dynamics is an ecological perspective that the structure, function, and dynamics of ecological systems can be understood through studying their interactive patches. Patch dynamics, as a term, may also refer to the spatiotemporal changes within and among patches that make up a landscape. Patch dynamics is ubiquitous in terrestrial and aquatic systems across organizational levels and spatial scales. From a patch dynamics perspective, populations, communities, ecosystems, and landscapes may all be studied effectively as mosaics of patches that differ in size, shape, composition, history, and boundary characteristics.

The organization is headquartered in Millbrook, New York, on a 2,000-acre (810 ha) research campus. Areas of expertise include disease ecology, urban ecology, freshwater ecology and provisioning, and forest health.
William H. Schlesinger is a biogeochemist and the retired president of the Cary Institute of Ecosystem Studies, an independent not-for-profit environmental research organization in Millbrook, New York. He assumed that position after 27 years on the faculty of Duke University, where he served as the Dean of the Nicholas School of the Environment and Earth Sciences and James B. Duke Professor of Biogeochemistry.
Landscape limnology is the spatially explicit study of lakes, streams, and wetlands as they interact with freshwater, terrestrial, and human landscapes to determine the effects of pattern on ecosystem processes across temporal and spatial scales. Limnology is the study of inland water bodies inclusive of rivers, lakes, and wetlands; landscape limnology seeks to integrate all of these ecosystem types.
Stephen Russell Carpenter is an American lake ecologist who focuses on lake eutrophication which is the over-enrichment of lake ecosystems leading to toxic blooms of micro-organisms and fish kills.
F. Herbert Bormann was an American plant ecologist whose 1971 research within the Hubbard Brook Experimental Forest in New Hampshire with fellow scientists was credited with the discovery of acid rain. His research was one of the major contributory factors towards changes made in the United States' Clean Air Act in 1990. In 1993 he was awarded the Tyler Prize for Environmental Achievement and in 2003 he received the Blue Planet Prize, both awards alongside his colleague Gene Likens. His publications include 8 books and more than 200 journal articles.
John D. Aber is University Professor Emeritus of Natural Resources & the Environment at the University of New Hampshire, and was also for many years affiliated with the Institute for the Study of Earth, Oceans, and Space at UNH. His fields of study included Ecosystem Analysis and Modeling, Global Change, Acid Rain, Nitrogen Deposition and Sustainable Agriculture.
Eville Gorham was a Canadian-American scientist whose focus has been understanding the chemistry of fresh waters and the ecology and biogeochemistry of peatlands. In the process, Gorham made a number of practical contributions that included discovering the influence of acid rain in lake acidification, plus the importance of the biological magnification of radioactive fallout isotopes in northern food chains. The former led to legislation and redesign of the power plants of the world to scrub sulfur, and the latter was an early step toward the establishment of an atmospheric nuclear test ban treaty.
