Many streams within the United States are impaired due to nutrient enrichment, particularly in agricultural settings. The present study examines the response of benthic algal communities in agricultural and minimally disturbed sites from across the western United States to a suite of environmental factors, including nutrients, collected at multiple scales.(More)
Stream metabolism was measured in 33 streams across a gradient of nutrient concentrations in four agricultural areas of the USA to determine the relative influence of nutrient concentrations and habitat on primary production (GPP) and respiration (CR-24). In conjunction with the stream metabolism estimates, water quality and algal biomass samples were(More)
Association between local land use and concentrations of selected herbicides in wetlands was examined at 31 sites in Nebraska. Sites were selected based on water depth, surface area, and the management of sites as wildlife habitat. In May and August 1994, water-column samples were collected at each of the sites and were analyzed for selected herbicides. The(More)
