Evaluation of the toxicity of marine sediments and dredge spoils with the MicrotoxR bioassay
The MicrotoxR bioassay was used to evaluate the toxicity of sediment and dredge spoil elutriates from several potentially-contaminated sites in Mobile and Pascagoula Bays. Elutriates were prepared using either local seawater or distilled deionized water (osmotically adjusted with NaCl prior to testing), and MicrotoxR assays were performed with the elutriates and three reference toxicants. There

Breeding biology and habitat use of black ducks
Forested wetlands are Important habitats for black ducks nesting in the Northeast. Invertebrates, with their high protein content, are primary foods of females during egg laying and for rapidly growing ducklings. Beaver-created and modified wetlands provide excellent habitat for feeding as well as protective cover. As these wetlands age, their quality declines after 7-10 years, and waterfowl use d

Rise and fall of endrin usage in Washington state fruit orchards: Effects on wildlife
A study of the effects of endrin on wildlife was conducted from 1981 to 1983 in fruit orchards in central Washington State. The single post-harvest application of endrin as a rodenticide resulted in both acute and chronic toxicity to a variety of avian species. Of 194 birds found dead, brains of 125 were analysed; endrin toxicosis accounted for >24% of the total and 37% of those analysed. Most mor

Effects of organophosphorus insecticides on sage grouse in southeastern Idaho
Unverified reports indicated die-offs of sage grouse have occurred since the 1970s in southeastern Idaho. Some verification that organophosphorus insecticides were involved was obtained in 1981 and 1983. A radio telemetry study indicated that dimethoate was responsible for most mortality. Methamidophos also acounted for mortality. Sage grouse populations may be adversely affected by organophos

Survival and movements of molting male black ducks in Labrador
We marked 26 flightless male American black ducks with transmitters during the post-nuptial molt in northern Labrabor to determine survival and movements. Twelve ducks remained in the watershed where marked and 11 ducks moved to different watersheds. The period survival rate (PSR) for these flightless males was 0.89 using the Kaplan-Meier estimator. Only 2 ducks were killed by predators. Death
