Graeme P. Berlyn, newly appointed as the E.H. Harriman Professor of Forest Management at the School of Forestry and Environmental Studies, is a specialist on the anatomy and physiology of trees.
A member of the Yale faculty since 1960, he is especially interested in light processing by leaves in relation to environmental factors as measured by chlorophyll fluorescence, photosynthesis, and spectral reflectance, absorption and transmission. His other research areas include the response of plants to natural stress, such as drought and predation, and man-made stress, such as acid rain and toxic chemicals.
Berlyn's current research is focused around two projects. The first is a study of the anatomical, physiological and optical properties of leaves in relation to light intensity and quality, distribution in tree crowns, nutrient status, and ecology and silviculture. The second concerns the development and use of organic biostimulants to maintain optimum plant growth while reducing fertilizer requirements and increasing natural stress resistance with respect to water, disease, insects and toxic substances. He is a co-holder of two patents for organic biostimulants that increase plant growth while decreasing fertilizer requirements and increasing drought resistance.
Berlyn came to Yale in 1960 as an instructor and curator of the Samuel James Record Collection of Tropical Woods. He became a full professor in 1978 and served from 1980 through 1988 as director of doctoral studies at the School of Forestry and Environmental Studies and as director of graduate studies at the Graduate School of Arts and Sciences.
A graduate of Iowa State University, where he also earned a Ph.D. in botany and forestry, Berlyn has been a visiting scientist or visiting professor at the U.S. Forest Service's Northern Institute of Forest Genetics in Wisconsin, Cornell University and the University of Kentucky. He is vice president and a trustee of the Biological Stain Commission and is editor of the Journal of Sustainable Forestry. He was elected a fellow of The International Academy of Wood Science in 1978.
