Diatom-based indicators were developed to assess environmental conditions in the Missouri, Ohio, and Upper Mississippi rivers. Disturbance gradients, comprising the first two principal components derived from a suite of stressor variables, included a trophic gradient (Trophic) and a gradient reflecting agriculture and other development activities (Ag/Dev).(More)
Denitrification dynamics in “geographically isolated wetlands” (GIWs) may provide a link between GIWs and aquatic systems by converting N to other end products (e.g., N2, N2O, etc.), protecting downstream waters from excessive N. We compared GIW ambient and amended denitrification rates and soil/water covariate relationships in areas of two ecoregions. The(More)
