Geomorphic, water quality and fish community patterns associated with the distribution of Notropis topeka in a Central Missouri Watershed Geomorphic, water quality and fish community patterns associated with the distribution of Notropis topeka in a Central Missouri Watershed
The Topeka shiner (Notropis topeka) is a small native cyprinid species that has declined throughout its range in the Central Great Plains Region of the United States. Declines of the species have been associated with numerous factors including water quality, physical habitat alteration and predation. The N. topeka occurs in the Moniteau Creek Watershed of Cooper and Moniteau Counties of...

Physical stream habitat dynamics in Lower Bear Creek, northern Arkansas Physical stream habitat dynamics in Lower Bear Creek, northern Arkansas
We evaluated the roles of geomorphic and hydrologic dynamics in determining physical stream habitat in Bear Creek, a stream with a 239 km2 drainage basin in the Ozark Plateaus (Ozarks) in northern Arkansas. During a relatively wet 12-month monitoring period, the geomorphology of Bear Creek was altered by a series of floods, including at least four floods with peak discharges exceeding a...

Hydrogeologic and ground-water-quality data for Belvidere, Illinois, and vicinity, 2001–02 Hydrogeologic and ground-water-quality data for Belvidere, Illinois, and vicinity, 2001–02
This report presents miscellaneous geologic, hydrologic, and ground-water-quality data collected in and near Belvidere, Ill. during May 2001–November 2002. The data were collected for two studies conducted by the U.S. Geological Survey during 1990–2002, but subsequent to publication of the final interpretive reports for the studies. The cooperative studies with the U.S. Environmental...

Survival, transport, and sources of fecal bacteria in streams and survival in land-applied poultry litter in the upper Shoal Creek basin, southwestern Missouri, 2001–2002 Survival, transport, and sources of fecal bacteria in streams and survival in land-applied poultry litter in the upper Shoal Creek basin, southwestern Missouri, 2001–2002
Densities of fecal coliform bacteria along a 5.7-mi (mile) reach of Shoal Creek extending upstream from State Highway 97 (site 3) to State Highway W (site 2) and in two tributaries along this reach exceeded the Missouri Department of Natural Resources (MDNR) standard of 200 col/100 mL (colonies per 100 milliliters) for whole-body contact recreation. A combination of techniques was used...

Heavy metals and metalloids in egg contents and eggshells of passerine birds from Arizona Heavy metals and metalloids in egg contents and eggshells of passerine birds from Arizona
Concentrations of inorganic elements were determined in eggs of passerine birds including the endangered southwestern willow flycatcher (Empidonax traillii extimus) from four regions in Arizona. The main aim of the study was to determine the distribution of metals in egg contents and eggshells, with emphasis on the deposition of Sr in eggshells. Seventy eggs of 11 passerine species were...

A pre-vegetated mat technique for the restoration of submersed aquatic vegetation A pre-vegetated mat technique for the restoration of submersed aquatic vegetation
Communities of submersed aquatic vegetation (SAV) provide critical habitat for wintering waterfowl and many commercially important fish species. Submersed aquatic vegetation also helps minimize storm damage by reducing wave action and stabilizing sediments, and they improve water quality by sequestering nutrients and contaminants (Zieman and Zieman 1989).
