个人简介

B.S. Brown University, Chemistry (1965) Ph.D. Purdue University, Physical Chemistry (1970) Charles Weston Pickard Professor of Chemistry and Biochemistry Dr. Page is a Professor of Chemistry and Biochemistry at Bowdoin College in Brunswick, Maine. His current responsibilities include teaching students courses in chemistry and in biochemistry, and conducting research in the area of marine environmental pol lution studies. He has also been a visiting scientist at the Skidaway Institute for Oceanography, Savannah, Georgia, and the Plymouth Marine Laboratory, Plymouth, England. Dr. Page has more than 130 professional publications, most dealing with various aspects of the fate and effects of petroleum and other pollutants on marine environments. He has conducted interdisciplinary studies with Dr. Edward Gilfillan on the fate and effects of oil spills on natural communities of animals and plants including ways in which to measure sublethal pollutant stress on plants and animals. Because oil spills occur in real-world environments, the presence of other natural and human factors have resulted in studies of the fate and effects of other pollutants such as heavy metals and alkyltins. Major oil spill studies include those from the following vessels; Tamano, Zoe Colocotroni, New Concord, Amoco Cadiz, Exxon Valdez, and many other smaller spills. Dr. Page has had extensive experience fingerprinting petroleum samples from over 75 mystery oil spills. Dr. Page has served as a testimonial expert in a variety of oil spill-related cases involving environmental damages including the Zoe Colocotroni, Amoco Cadiz, and Exxon Valdez, (State and Federal) litigations. He is a member of the Society of Environmental Toxicologists and Chemists and of the American Chemical Society.

研究领域

As a population geneticist, I am interested in how genes change from one generation to the next and among contemporary populations. I have carried out research investigating each of the five evolutionary forces: selection, mutation, genetic drift, gene flow, and non-random mating. I am also interested in ecology as the arena in which evolution takes place. I work on plants because of their beauty and inherent interest as well as their many desirable attributes as study organisms. Most of my projects combine molecular genetic analysis with various kinds of phenotypic data.

With Juvenal Lopez ’16, I am examining the population genetic structure of a wild population of pin oak (Quercus palustris) that has spread in Colby woodlands from ornamental plantings. We are interested in the role of hybrid vigor in facilitating range expansions as manifested by invasive introduced species. I am investigating the role of colonization and gene flow on the mating system for populations of a tropical shrub, Witheringia solanacea, on the Pacific Slope of Costa Rica. In addition, I will be comparing contemporary gene flow by bird-dispersed seeds to historical gene flow as inferred by genetic markers. In my most recent completed project, with the help of dozens of Colby students and two Costa Rican technicians, I demonstrated that the evolution of self-fertilization in small populations was promoted more by siring success than by enhanced capacity to set fruit when pollinators were scarce.
