The ecology of cormorants: some research needs and recommendations The ecology of cormorants: some research needs and recommendations
Concerns about Double-crested Cormorants (Phalacrocorax auritus) have arisen because of their rapid population increase across North America and their economic impact on several aquaculture and commercial fish industries. In spite of the concern for cormorants, little published research is available that addresses either basic population biology questions or management issues. Based on a

Wildlife toxicity testing Wildlife toxicity testing
Reports of anthropogenic environmental contaminants affecting free-ranging wildlife first began to accumulate during the Industrial Revolution of the 1850s. early reports included cases of arsenic and lead shot ingestion, and industrial smokestack emission toxicity. One early report described the death of fallow deer (Dama dama) due to arsenic emissions from a silver foundry in Germany...

Making sense of soil ecotoxicology Making sense of soil ecotoxicology
The toxicity of pesticides and environmental contaminants to soil organisms has been measured in studies on earthworms,1 soil arthropods,3-6 soil microorganisms,7 and other soil organisms.8 Toxicity data on earthworms produced in the pesticide registration procedure required by the OECD (Organization for economic cooperation and Development) will provide data on many additional...

Ground-water quality in northeastern St. Joseph County, Indiana Ground-water quality in northeastern St. Joseph County, Indiana
This report describes the ground-water quality of a 220-square-mile area in northeastern St. Joseph County, Indiana. Ground-water samples were collected from 30 monitoring wells at 20 sites during May 1992; the wells were screened in either a shallow or a deep sand and gravel aquifer. Samples were analyzed for general water-quality properties, nutrients, major ions, trace elements...

Hydrogeology and water quality at the management systems evaluation area near Piketon, Ohio Hydrogeology and water quality at the management systems evaluation area near Piketon, Ohio
This report presents the results of a study by the U.S. Geological Survey, The Ohio State University, and the U.S. Department of Agriculture to describe the hydrology, water quality, and geochemical factors controlling water quality at the Ohio Management Systems Evaluation Area (MSEA). The Ohio MSEA is located on a 650-acre farm in the Scioto River Valley in Pike County, south-central...

Simulation of streamflow and sediment transport in two surface-coal-mined basins in Fayette County, Pennsylvania Simulation of streamflow and sediment transport in two surface-coal-mined basins in Fayette County, Pennsylvania
The Hydrological Simulation Program - Fortran (HSPF) was used to simulate streamflow and sediment transport in two surface-mined basins of Fayette County, Pa. Hydrologic data from the Stony Fork Basin (0.93 square miles) was used to calibrate HSPF parameters. The calibrated parameters were applied to an HSPF model of the Poplar Run Basin (8.83 square miles) to evaluate the transfer value...

Use of stable isotopes of carbon, nitrogen, and sulfer to identify sources of nitrogen in surface waters in the Lower Susquehanna River basin, Pennsylvania Use of stable isotopes of carbon, nitrogen, and sulfer to identify sources of nitrogen in surface waters in the Lower Susquehanna River basin, Pennsylvania
Stable isotopes of carbon (C), nitrogen (N), and sulfur (S) in nitrogen sources and nearby samples of topsoil, subsoil, runoff water, and stream water were measured to evaluate the feasibility of using isotopic data to identify nitrogen sources in stream water from forested, agricultural, or suburban land-use areas. Chemical and isotopic compositions were measured for six N-source types...

Decadal and annual changes in biogenic opal and carbonate fluxes to the deep Sargasso Sea Decadal and annual changes in biogenic opal and carbonate fluxes to the deep Sargasso Sea
Analyses of samples from a 14-year series of sediment-trap deployments in the deep Sargasso Sea reveal a significant trend in the ratio of the sinking fluxes of biogenic calcium carbonate and silica. Although there are pronounced seasonal cycles for both flux components, the overall opal/CaCO3 ratio changed by 50% from 1978 to 1991 (largely due to a decrease of opal flux), while total...
