Demographic Toxicity

H. Resit Akcakaya is Senior Scientist at Applied Biomathematics, an ecological research and software company in Setauket, NY. His current research interests include risk assessment, population viability analysis, and the effects of landscape dynamics on species persistence. One of the principal architects of the RAMAS library of software, he developed models for integrating metapopulation and landscape dynamics, and for incorporating uncertainty into IUCN criteria for threatened species. John Stark is a professor at the Washington State University, Puyallup Research and Extension Center. He runs the Ecotoxicology program. The mission of the Ecotoxicology program at WSU Puyallup is to study the impacts of pesticides and other toxicants on populations, communities, and food webs with particular emphasis on aquatic organisms inhabiting rivers and streams in the Pacific Northwest, including salmon and the invertebrates that they feed upon. Todd S. Bridges is the Director of Center for Contaminated Sediments at US Army Corps of Engineers' Waterways Experiment Station in Vicksburg, MS. He received an undergraduate degree (1985) and a Master of Arts degree (1988) in Biology from California State University, Fresno, and a Ph.D. (1992) in Biological Oceanography from North Carolina State University. His research expertise includes aquatic and marine ecology, aquatic toxicology, and invertebrate physiology and ecology, and ecological risk assessment.
