| integrated assessment of contaminated sediments in the lower fox river and green bay, wisconsin. | samples of sediment and biota were collected from sites in the lower fox river and southern green bay to determine existing or potential impacts of sediment-associated contaminants on different ecosystem components of this great lakes area of concern. evaluation of benthos revealed a relatively depauperate community, particularly at the lower fox river sites. sediment pore water and bulk sediments from several lower fox river sites were toxic to a number of test species including pimephales prom ... | 1992 | 1375148 |
| investigation of fathead minnows (pimephales promelas) as a biological control agent of culex mosquitoes under laboratory and field conditions. | many urban areas have engineered storm-water runoff control structures such as ditches and detention ponds. these often serve as excellent habitats for culex pipiens and culex restuans, the primary enzootic vectors of west nile virus in the midwest. we evaluated predation and control of these species by a fish species native to wisconsin, the fathead minnow (pimephales promelas). in the lab, a single minnow consumed an average of 74 cx. pipiens larvae in a 24-h period. minnow gender and age had ... | 2009 | 19852220 |
| metformin exposure at environmentally relevant concentrations causes potential endocrine disruption in adult male fish. | pharmaceuticals and personal care products (ppcps) are emerging contaminants that have been found ubiquitously in wastewater and surface waters around the world. a major source of these compounds is incomplete metabolism in humans and subsequent excretion in human waste, resulting in discharge into surface waters by wastewater treatment plant (wwtp) effluent. one pharmaceutical found in particularly high abundance in recent wwtp effluent and surface water studies is metformin, one of the world's ... | 2015 | 25358780 |
| isolation and molecular characterization of a novel picornavirus from baitfish in the usa. | during both regulatory and routine surveillance sampling of baitfish from the states of illinois, minnesota, montana, and wisconsin, usa, isolates (n = 20) of a previously unknown picornavirus were obtained from kidney/spleen or entire viscera of fathead minnows (pimephales promelas) and brassy minnows (hybognathus hankinsoni). following the appearance of a diffuse cytopathic effect, examination of cell culture supernatant by negative contrast electron microscopy revealed the presence of small, ... | 2014 | 24586283 |
