Behavioral indicators of sublethal toxicity in rainbow trout Behavioral indicators of sublethal toxicity in rainbow trout

Four measures of behavior-spontaneous swimming activity, swimming capacity, feeding behavior, and vulnerability to predation-were assessed as indicators of sublethal toxicity in rainbow trout (Oncorhynchus mykiss) in 96-hr exposures to sublethal concentrations of six agricultural chemicals: carbaryl, chlordane, dimethylamine salt of 2,4-dichlorophenoxyacetic acid (2,4-DMA), tributyl

Eocene-Oligocene sea-level changes on the New Jersey coastal plain linked to the deep-sea record Eocene-Oligocene sea-level changes on the New Jersey coastal plain linked to the deep-sea record

We use magnetostratigraphy and Sr-isotope stratigraphy to improve stratigraphic control for the Eocene to Oligocene of the New Jersey coastal plain (ACGS4 borehole). Magnetostratigraphy in many cases is complicated in outcrop sections of shallow-water (

Automatic tracer-dilution method used for stage-discharge ratings and streamflow hydrographs on small Iowa streams Automatic tracer-dilution method used for stage-discharge ratings and streamflow hydrographs on small Iowa streams

An automatic system was designed to concurrently measure stage and discharge for the purpose of developing stage-discharge ratings and high flow hydrographs on small streams. Stage, or gage height, is recorded by an analog-to-digital recorder and discharge is determined by the constant-rate tracer-dilution method The system measures flow above a base stage set by the user. To test the

Water-resources potential of the freshwater lens at Key West, Florida Water-resources potential of the freshwater lens at Key West, Florida

The island of Key West lies at the end of the Florida Keys, about 150 miles southwest of Miami. The public-water supply for the island is provided by the Florida Keys Aqueduct Authority Well Field near Miami. However, there are many privately owned wells on the island that tap the local fresh ground-water lens for potable and nonpotable water supply. The number of people who use water...

Influence of ingested lead on body mass of wintering canvasbacks Influence of ingested lead on body mass of wintering canvasbacks

We determined the prevalence of lead shotgun pellets in gizzards of canvasbacks (Aythya valisineria) collected at Catahoula Lake and the Mississippi River Delta, Louisiana, during winter 1987-88 to assess the influence of ingested lead shot on canvasback body mass. The prevalence of ingested lead shot was significantly higher at Catahoula Lake (27%) than at the Mississippi River Delta (4...
