Geographic information system (GIS) technology was used to identify habitats available to and used by male American woodcock (Scolopax minor) equipped with radio transmitters--54 in 1987, 51 in 1988, 46 in 1989 at Moosehorn National Wildlife Refuge, Maine. Woodcock were monitored from time of capture (25 March-15 April) to 15 June each year. To determine habitat selection by male...

A feeding trial was conducted to determine the effect of supplementing a diet based on hydrolyzed fish meal with either 6% chitin (as ground krill shell), 6% squid meal, or 200 mg carotenoid pigment (canthaxanthin) per kilogram on dorsal fin erosion in juvenile steelhead Oncorhynchus mykiss. Three hundred fry in triplicate tanks were fed one of the four test diets, and 300 fry in a...

Diffusion samplers were installed in the bottom of Johns Pond, Cape Cod, Massachusetts, to confirm that volatile organic compounds from the Storm Drain-5 (SD-5) plume emanating from the Massachusetts Military Reservation (MMR) were discharging into the pond. An array of 134 vapor-diffusion samplers was buried by divers about 0.5 feet below the pond bottom in the presumed discharge area...

During this study, 369 benthic-invertebrate samples were collected at 21 sites and 33 streambed-sediment samples were collected at 14 sites to help develop and evaluate control strategies to mediate the impact of point and nonpoint sources of pollution on the White River and selected tributaries in and near Indianapolis, Indiana. Data analyses show that 124 taxa were identified and that...

The Grand Calumet River, in northwestern Indiana, drains a heavily industrialized area along the southern shore of Lake Michigan. Steel production and petroleum refining are two of the area’s predominant industries. High-temperature processes, such as fossil fuel combustion and steel production, release contaminants to the atmosphere that may result in wet deposition being a major...

Part of the 1998 Industrial Minerals Review. Activities in the kaolin industry in 1999 are reviewed. U.S. production of kaolin in 1999 was estimated to be 10.7 million st, an increase of 0.3 million st from the previous year. The paper industry is the largest user of kaolin, accounting for 59 percent of domestic sales. Company activities, announcements, and plans of interest to the...

Anthropogenic changes to the biosphere, including widespread degradation and losses of habitats and ecosystems, are causing rapid and profound changes to bird and other wildlife populations throughout the world. Such changes have led to increasing risks and rates of extinction. As a consequence, information on how bird populations are changing is becoming increasingly important to...

Informed management requires information about system state and about effects of potential management actions on system state. Population monitoring can provide the needed information about system state, as well as information that can be used to investigate effects of management actions. Three methods for investigating effects of management on bird populations are (1) retrospective...

The upper reaches of the Allegheny River are a high-quality resource that supports populations of a number of endangered species. Two endangered species of freshwater mussel, the northern riffleshell, Epioblasma torulosa rangiana, and clubshell, Pleurobema clava, are present in this river reach. Prior to a bridge-replacement project at the Allegheny River at Foxburg, Pa. (river mile 86.2...
