Toxicity of Abate to green frog tadpoles Toxicity of Abate to green frog tadpoles
Green frog tadpoles were exposed to a 96hr toxicity test using Abate4E, the formulation for temephos used in mosquito control. Concentrations ranged from 0 (control) to 10 uL/L. Concentrations as low as 2.60 uL/L reduced activity for several hours after exposure but had negligible effects after 24 hr, presumably because the temephos had degraded during that time. The LC50 for Abate was 4...

Toxicity of alkalinity to Hyalella azteca Toxicity of alkalinity to Hyalella azteca
Toxicity testing and chemical analyses of sediment pore water have been suggested for use in sediment quality assessments and sediment toxicity identification evaluations. However, caution should be exercised in interpreting pore-water chemistry and toxicity due to inherent chemical characteristics and confounding relationships. High concentrations of alkalinity, which are typical of...

Effectiveness of mitigation measures with constructed forested wetlands in Maryland Effectiveness of mitigation measures with constructed forested wetlands in Maryland
Intensive research on six constructed forested wetlands in Central Maryland was conducted in 1993-1996 to determine success of these habitats as functional forested wetlands for wildlife. Areas studied ranged in size from 2 to 35 acres and were constructed by private companies under contract with three mitigation agencies. Adjacent natural forested wetlands were used as reference sites...

Reproduction of black-crowned night-herons related to predation and contaminants in Oregon and Washington, USA Reproduction of black-crowned night-herons related to predation and contaminants in Oregon and Washington, USA
We studied reproductive characteristics of Black-crowned Night-Herons (Nycticorax nycticorax) at four colonies in south central Washington and one colony in north central Oregon in 1991. Nest success, adjusted using the Mayfield method, was significantly different between colonies and ranged from 12-84% to hatching and 12-73% to 14 days post-hatching. The mean number of young surviving...

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...
