About the Author
Dr Weathers is a Biogeochemist with an expertise in air-land-water interactions, heterogeneous landscapes, ecological importance of fog, air pollution. Dr. Weathers' research focuses on quantifying how biology affects geochemistry and biogeochemical cycling across heterogeneous landscapes, and within and among multiple systems (air-land-water). Specific topics have included quantifying cross-boundary nutrient fluxes (e.g., nutrient and pollutant delivery and biogeochemistry from ocean to forest); how landscape and plant structure affect fog inputs-and how fog affects the biotic and abiotic maintenance of ecosystems; the importance of tree species, and their pests and pathogens, in controlling landscape biogeochemistry; and the effect of cyanobacteria on oligotrophic lake resilience. She has over 100 publications to date Dr Strayer is a Freshwater Ecologist whose research is focused on the distribution and roles of freshwater invertebrates. He is currently working on the ecology of the Hudson River and on understanding the controls on distribution and abundance of pearly mussels. He has over 100 publications to date. Dr Likens is an Ecologist with expertise in ecosystem ecology, biogeochemistry, acid rain, and human impacts on aquatic and terrestrial ecosystems. His research focuses on the ecology and biogeochemistry of both forest and aquatic ecosystems. He was the co-founder of the Hubbard Brook Ecosystem study which discovered the links between ecosystem function and land-use practices. He and his colleagues were the first to discover acid rain in North America and to document the link between the combustion of fossil fuels and the increase of the acidity of precipitation. He was, in fact, subsequently rewarded with the National Medal of Science for his work in ecology. He has over 300 publications to date.
