growth and at what factors may affect the metropolitan area’s future. Adams holds two degree in economics and a doctorate in urban geography from the University of Minnesota.

BARBARA L. BEDFORD is a Senior Research Associate at Cornell University. She joined the Department of Natural Resources in 1989, having served as the Associate Director of Cornell University's Ecosystems Research Center since 1980. Her research focuses on wetland plant diversity, what controls it, how human actions affect it, and how to manage it. She and her students work primarily in fens, bogs, riparian wetlands, and Great Lakes wetlands. Current projects include: (a) relationship of groundwater hydrology and chemistry to nutrient availability, plant productivity, and plant species diversity; (b) inter-relationships among nutrient availability, plant tissue chemistry, and plant species diversity; (c) landscape control of wetland biogeochemistry and hydrology; (d) effects of removing cattails on fen species composition and diversity; and plant species diversity in phosphorus-poor wetlands. She teaches courses in Wetland Ecology and Management and Landscape Analysis. She served on the NRC Committee on Review of Scientific Research Programs at the Smithsonian Institution, and the Committee on Wetlands Characterization. She received a B.A. from Marquette University in 1968, and her M.S. and Ph.D. from the University of Wisconsin at Madison in 1977 and 1980, respectively.

LINDA K. BLUM is research associate professor in the Department of Environmental Sciences at the University of Virginia. Her current research projects include study of mechanisms controlling bacterial community abundance, productivity, and structure in tidal marsh creeks; impacts of microbial processes on water quality; organic matter accretion in salt marsh sediments; and rhizosphere effects on organic matter decay in anaerobic sediments. Dr. Blum earned a B.S. and M.S. in forestry from Michigan Technological University and a Ph.D. in soil science from Cornell University. She chaired the NRC committee that recently completed a study of the Critical Ecosystem Studies Initiative.

PATRICK L. BREZONIK is professor of environmental engineering and director of the Water Resources Research Center at the University of Minnesota. Prior to his appointment at the University of Minnesota in the mid-1980s, Dr. Brezonik was professor of water chemistry and environmental science at the University of Florida. His research interests focus on biogeochemical processes in aquatic systems, with special emphasis on the impacts of human activity on water quality and element cycles in lakes. He has served as a member of the National Research Council’s Water Science and Technology Board and as a member of several of its committees. He earned a B.S. in chemistry from Marquette University and a M.S. and Ph.D. in water chemistry from the University of Wisconsin-Madison.

FRANK W. DAVIS is a Professor at the University of California Santa Barbara (USCB) with appointments in the Donald Bren School of Environmental Science and Management and the Department of Geography. He received his B.A. in biology from Williams College and a Ph.D. from the Department of Geography and Environmental Engineering at The Johns Hopkins University. He joined the Department of Geography at UCSB in 1983, and established the UCSB Biogeography Lab in 1991. His research focuses on the ecology and management of California chaparral and oak woodlands, landscape ecology, regional conservation planning, and spatial decision support systems. He was Deputy Director of the National Center for Ecological Analysis and Synthesis between 1995 and 1998, and currently directs the Sierra
