Effects of weather and tides on feeding and flock positions of wintering redheads in the Chandeleur Sound, Louisiana Effects of weather and tides on feeding and flock positions of wintering redheads in the Chandeleur Sound, Louisiana
We studied the effects of weather and tides on percent feeding and flock positions of wintering redheads (Aythya americana Eyton) in the Chandeleur Sound, Louisiana, USA. Flock scans (n = 750) were made on 55 flocks from November through March of 1988–1989. The percent of the flock that was feeding was negatively correlated with time of day, temperature, water level, and distance of the...

Mangroves, hurricanes, and lightning strikes: Assessment of Hurricane Andrew suggests an interaction across two differing scales of disturbance Mangroves, hurricanes, and lightning strikes: Assessment of Hurricane Andrew suggests an interaction across two differing scales of disturbance
The track of Hurricane Andrew carried it across one of the most extensive mangrove for ests in the New World. Although it is well known that hurricanes affect mangrove forests, surprisingly little quantitative information exists concerning hurricane impact on forest structure, succession, species composition, and dynamics of mangrove-dependent fauna or on rates of eco-system recovery...

Evaluation of effects caused by high copper concentrations in Torch Lake, Michigan, on reproduction of yellow perch Evaluation of effects caused by high copper concentrations in Torch Lake, Michigan, on reproduction of yellow perch
Elevated concentrations of copper are present in Torch Lake, Michigan, an Environmental Protection Agency Superfund site. The sauger (Stizostedion canadense) population in Torch Lake has been extirpated and walleye (Stizostedion vitreum) populations are maintained by stocking. We used yellow perch (Perca flavescens) to determine if chronic exposure to elevated copper concentrations has...

Hepatic cadmium, metal-binding proteins and bioaccumulation in bluegills exposed to aqueous cadmium Hepatic cadmium, metal-binding proteins and bioaccumulation in bluegills exposed to aqueous cadmium
We examined sublethal responses of juvenile bluegills Lepomis macrochirus to aqueous cadmium in two 28-d tests (test I, 0.0-8.4 μg Cd per liter; test II, 0.0-32.3 μg Cd per liter) in an intermittent-flow diluter. The experimental design was completely randomized, with two replicates in each of eight treatments (seven Cd exposures and one water control with 25 fish per replicate). Cadmium...
