Disposition of 1-naphthol in the channel catfish (Ictalurus punctatus) Disposition of 1-naphthol in the channel catfish (Ictalurus punctatus)
The pharmacokinetics, tissue distribution, and metabolism of 1-naphthol were examined in the channel catfish (Ictalurus punctatus ). After oral dosing, peak plasma concentrations of 1-naphthol occurred at 1 hr; parent compound made up less than 15% of the total radioactivity, and the bioavailability was 32%. Plasma protein binding was 92% and was independent of concentration. 1-Naphthol...

Feeding flights of breeding double-crested cormorants at two Wisconsin colonies Feeding flights of breeding double-crested cormorants at two Wisconsin colonies
Unmarked Double-crested Cormorants (Phalacrocorax auritus ) were followed by airplane from Cat Island and Spider Island, two nesting colonies in Wisconsin, to their first landing site. Cormorants flew an average of 2.0 km from Cat Island (maximum 40 km) and 2.4 km from Spider Island (maximum 12 km). The mean direction of landing sites differed seasonally for flights from Spider Island...

Sublethal effects of cadmium on physiological responses in the pocketbook mussel, Lampsilis ventricosa Sublethal effects of cadmium on physiological responses in the pocketbook mussel, Lampsilis ventricosa
Recent studies indicate that the density and diversity of freshwater mussels are declining in many large river systems, possibly from low-level chemical contamination. Exposure of Lam-psilis ventricosa (Barnes, 1823) to 0, 22, 111, and 305 μg/L of cadmium for 28 d in a proportional diluter resulted in a significant decrease (p ≤ 0.05) in respiration rate as cadmium concentration...

Heavy metals in the threeridge mussel Amblema plicata plicata (Say, 1817) in the upper Mississippi River Heavy metals in the threeridge mussel Amblema plicata plicata (Say, 1817) in the upper Mississippi River
Concentrations of mercury and zinc in the threeridge mussel Amblema plicata plicata, sampled in 1987 from Pools 3 and 10 in the upper Mississippi River, were comparable to concentrations in mussels from moderately contaminated systems, while copper concentrations were similar to concentrations in mussels from more polluted waters. Cadmium concentrations in mussels were significantly less...

Cadmium and mercury in emergent mayflies (Hexagenia bilineata) from the upper Mississippi River Cadmium and mercury in emergent mayflies (Hexagenia bilineata) from the upper Mississippi River
Burrowing mayflies (Hexagenia bilineata) were analyzed to assess longitudinal patterns in their cadmium and mercury content along the upper Mississippi River. Emergent mayflies (subimagoes and imagoes) were collected in 1988 at 34 sites (25 navigation pools), extending 1260 km from Little Falls, Minnesota, downstream to St. Louis, Missouri. Cadmium concentrations in composite samples of...

Accumulation of mercury by aufwuchs in Wisconsin seepage lakes: Implications for monitoring Accumulation of mercury by aufwuchs in Wisconsin seepage lakes: Implications for monitoring
We examined temporal variation in the total Hg content of aufwuchs collected from artificial substrates in 11 seepage lakes in north-central Wisconsin and its relation to the Hg content of resident yellow perch Perca flavescens from the lakes. Dry weight concentrations of Hg in aufwuchs varied temporally, as follows: summer/fall 1985 > summer 1985 > spring/summer 1986. Areal...

Flooding mortality and habitat renewal for least terns and piping plovers Flooding mortality and habitat renewal for least terns and piping plovers
We observed extensive mortality (eggs and chicks) of the endangered interior population of the Least Tern (Sterna antillarum) and threatened Piping Plover (Charadrius melodus) caused by natural flooding during the 1990 breeding season along the Platte River, Nebraska USA. Aerial videography of the Platte River before and after the flood revealed a 78% reduction of perennial vegetation on...
