Technology Transfer Opportunities: Automated Ground-Water Monitoring Technology Transfer Opportunities: Automated Ground-Water Monitoring
Introduction A new automated ground-water monitoring system developed by the U.S. Geological Survey (USGS) measures and records values of selected water-quality properties and constituents using protocols approved for manual sampling. Prototypes using the automated process have demonstrated the ability to increase the quantity and quality of data collected and have shown the potential...

Secondary poisoning of kestrels by white phosphorus Secondary poisoning of kestrels by white phosphorus
Since 1982, extensive waterfowl mortality due to white phosphorous (P4) has been observed at Eagle River Flats, a tidal marsh near Anchorage, Alaska. Ducks and swans that ingest P4 pellets become lethargic and may display severe convulsions. Intoxicated waterfowl attract raptors and gulls that feed on dead or dying birds. To determine if avian predators can be affected by secondary...

Cytochrome P450 and organochlorine contaminants in black-crowned night-herons from the Chesapeake Bay region, USA Cytochrome P450 and organochlorine contaminants in black-crowned night-herons from the Chesapeake Bay region, USA
Black-crowned night-heron (Nycticorax nycticorax) offspring were collected from a relatively uncontaminated coastal reference site (next to Chincoteague National Wildlife Refuge, VA, USA) and two sites in the Chesapeake Bay watershed (Baltimore Harbor, MD and Rock Creek Park, Washington, DC, USA). Hepatic microsomal activities of benzyloxyresorufin-O-dealkylase and ethoxyresorufin-O...

Acidification of experimental wetlands: Effects on wetland productivity and survival of juvenile black ducks Acidification of experimental wetlands: Effects on wetland productivity and survival of juvenile black ducks
Six man-made wetlands (0.02 ha each) and pen-reared broods of American black ducks (Anas rubripes) were used to assess the effects of reduced pH on the quality of fish- free, palustrine habitat for brood rearing. Acid treatment was assigned randomly among newly constructed wetlands during April through June 1984-85, to simulate depressed pH from snowmelt and spring rain. Sampling of...

A new database on contaminant exposure and effects in terrestrial vertebrates for natural resource managers A new database on contaminant exposure and effects in terrestrial vertebrates for natural resource managers
The Biomonitoring of Environmental Status and Trends (BEST) program of the Department of the Interior is focused to identify and understand effects of contaminant stressors on biological resources under their stewardship. Despite the desire of many to continuously monitor the environmental health of our estuaries, much can be learned by summarizing existing temporal, geographic, and...

Development of an IBI-based assessment of depressional wetlands in Maryland and Delaware Development of an IBI-based assessment of depressional wetlands in Maryland and Delaware
The hydrogeomorphic approach (HGM) of wetland assessment emphasizes functional components of wetlands such as water storage, transformation and cycling of elements, accumulation of sediments, and preservation of habitats. Many of the elements measured in HGM are physical rather than ecological or biological. The HGM approach, therefore, provides information on certain aspects of wetlands...

Densities of breeding American black ducks in southcentral Maine: 1958-60 and 1978-80 Densities of breeding American black ducks in southcentral Maine: 1958-60 and 1978-80
Numbers of wetlands and amount of surface water (ha) within a 105 km2 area increased substantially between 1958-60 and 1978-80 in southcentral Maine. Conversely, in 1978-80 mean numbers of black duck pairs (11.9/100 ha surface water) and broods (10.8/100 ha surface water) were lower than for 1958-60 (pairs = 23.3; broods = 13.3) for wetlands surveyed in both periods. Differences in pairs...

Causes of Mississippi sandhill crane mortality in captivity 1984-95 Causes of Mississippi sandhill crane mortality in captivity 1984-95
During 1984-95, 111 deaths were documented in the captive flock of Mississippi sandhill cranes (Grus canadensis pulla) housed at the Paluxent Wildlife Research Center. Trauma was the leading cause of death (37%), followed by infectious/parasitic diseases (25%), anatomic abnormalities (15%), and miscellaneous (8%). No positive diagnosis of cause of death was found in 19% of the necropsies...
