Dissolved organic nitrogen (DON) is an issue for the water field primarily due to the
formation of disinfection by-products of health concern, and its potential role in membrane …

Dissolved organic matter (DOM) composition in freshwater ecosystems is influenced by the
interactions among physical, chemical, and biological processes that are controlled, at one …

Nitrogen (N) and phosphorus (P) commonly co-limit primary productivity in lakes, and
chlorophyll a (Chl-a) is predicted to be greatest under high N, high P regimes. Because land …

The growth and development of Anopheles gambiae Giles larvae were studied in artificial
habitats in western Kenya. Larvae responded to increasing densities by extending their …

This study tests the hypothesis that lakes in watersheds dominated by row‐crop agriculture
(eg, maize or soybeans) have systematically higher N: P than lakes in watersheds with large …

Understanding concentrations and contributions of carbon dioxide (CO2) in aquatic
ecosystems is an important part of a comprehensive global carbon budget. Current dogma …

Blooms of blue-green algae (BGA) threaten drinking water safety and ecosystems
worldwide. Understanding mechanisms and driving factors that promote BGA proliferation is …

An important objective in understanding harmful phytoplankton blooms is determining how
environmental factors influence the toxicity of bloom-forming species. We examined how …

Recently, interest in denitrification bioreactors to reduce the amount of nitrate in agricultural
drainage has led to increased installations across the US Midwest. Despite this recent …

Linking fecal indicator bacteria concentrations in large mixed-use watersheds back to diffuse
human sources, such as septic systems, has met limited success. In this study, 64 rivers that …
