Late winter survival of female mallards in Arkansas Late winter survival of female mallards in Arkansas

Determining factors that limit winter survival of waterfowl is necessary to develop effective management plans. We radiomarked immature and adult female mallards (Anas platyrhynchos) after the 1988 and 1989 hunting seasons in eastcentral Arkansas to test whether natural mortality sources and habitat conditions during late winter limit seasonal survival. We used data from 92 females to...

Habitat use by an endangered riverine fish and implications for species protection Habitat use by an endangered riverine fish and implications for species protection

We investigated habitat specificity of the amber darter (Percina antesella Williams & Etnier 1977), an imperiled fish from restricted portions of 2 rivers in the southeastern United States. Foraging amber darters occupied a narrow range of riffle habitat, consistently avoiding areas 20 cm deep and with velocity 10 cm. s-1 near the substrate, occupying areas with cobble or gravel...

Buffer zones of territories of gray wolves as regions of intraspecific strife Buffer zones of territories of gray wolves as regions of intraspecific strife

The locations of 22 territorial gray wolves (Canis lupus) killed by conspecifics in northeastern Minnesota were analyzed in a study involving radio-telemetry from 1968 through 1992. Twenty-three percent of the wolves were killed precisely on the borders of their estimated territories; 41%, within 1.0 km (16% of the radius of their mean-estimated territory) inside or outside the estimated...

Famphur Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review Famphur Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review

Famphur (phosphorothioic acid, O,(4((dimethylamino)sulfonyl),phenoyl)O,Odimethyl ester), also known as Warbex, is a systemic organophosphorus insecticide used almost exclusively as a veterinary chemical to control parasite in livestock. Only famphur and its oxygen analog, famoxon, were of toxicological significance; other famphur metabolites were 31 to 237 times less toxic, as Judged by...
