Metal contamination in wildlife living near two zinc smelters
W. N. Beyer, O. H. Pattee, L. Sileo, D. J. Hoffman, B.M. Mulhern
1985, Environmental Pollution (Series A) (38) 63-86
Wildlife in an oak forest on Blue Mountain was studied 10 km upwind (Bake Oven Knob site) and 2 km downwind (Palmerton site) of two zinc smelters in eastern Pennsylvania, USA. Previous studies at sites near these smelters had shown changes in populations of soil microflora, lichens, green plants and...
Reproduction, mortality, and heavy metal concentrations in great blue herons from three colonies in Washington and Idaho
L. J. Blus, Charles J. Henny, A. Anderson, R. E. Fitzner
1985, Colonial Waterbirds (8) 110-116
We collected eggs in nests, hatchlings and eggs with advanced embryos on the ground, and prefledgling young of Great Blue Herons (Ardea herodias) at three nesting colonies in Washington and Idaho. Intact fish were also collected on the ground at the Idaho colony. The Ft. Lewis colony near...
Organochlorine concentrations in prefledging common terns at three Rhode Island colonies
T. W. Custer, C.M. Bunck, C. J. Stafford
1985, Colonial Waterbirds (8) 150-154
Concentrations of DDE, polychlorinated biphenyls (PCBs), and polychlorinated diphenyl ethers (PCDPEs) in carcasses of prefledging Common Terns (Sterna hirundo) at three Rhode Island colonies support the hypothesis that local contamination is responsible for among-colony differences observed in eggs in an earlier study. The highest concentrations of DDE and PCBs (mean...
Organochlorine residues and eggshell measurements for tree swallows Tachycineta bicolor in Colorado
Lawrence R. DeWeese, Ronald R.H. Cohen, Charles J. Stafford
1985, Bulletin of Environmental Contamination and Toxicology (35) 767-775
This paper reports organochlorine (OCL) concentrations in breeding female tree swallows, nestlings, and eggs, and measurements of egg size and eggshell thickness. Our objective was to determine if higher concentrations of OCL chemicals were associated with adult mortality or nesting failure....
Sperm whales (Physeter catodon) in the Gulf of Mexico
L.A. Collum, T. H. Fritts
1985, Southwestern Naturalist (30) 101-104
The distribution of the sperm whale, Physeter catodon, was documented in the Gulf of Mexico during 1979 to 1981 using regular aerial surveys and opportunistic sightings from ships. Most sightings were in the western Gulf of Mexico in deep waters near the edge of the continental shelf. A total of...
Toxicity to woodlice of zinc and lead oxides added to soil litter
W. N. Beyer, A. Anderson
1985, Ambio (14) 173-174
Previous studies have shown that high concentrations of metals in soil are associated with reductions in decomposer populations. We have here determined the relation between the concentrations of lead and zinc added as oxides to soil litter and the survival and reproduction of a decomposer population under controlled conditions. Laboratory...
Deposition of anal-sac secretions by captive wolves (Canis lupus)
C. S. Asa, E.K. Peterson, U.S. Seal, L.D. Mech
1985, Journal of Mammalogy (66) 89-93
Deposition of anal-sac secretions by captive wolves was investigated by a labelling technique using protein-bound iodine125 and food dye. Wolves deposited secretions on some but not all scats. Adult males, especially the alpha male, deposited anal-sac secretions more frequently while defecating than did females or juveniles. Secretions sometimes also were...
Growth and blood chemistry of ducklings reared on acidified wetlands
Barnett A. Rattner, G. Haramis, G. Linder, D. Chu
1985, American Zoologist (25) 17A-17A
Acid deposition is one factor that may be responsible for the decline of some waterfowl populations. Growth and physiological condition were monitored in captive-reared black ducks (Anas rubripes) exposed for 10-day trials (day 11-20 of life) on control (pH 6.8) and acidified (pH 5.0) man-made emergent wetlands. Impaired...
Tenth anniversary meeting keynote address
J. Michael Scott
1985, Pacific Seabird Group Bulletin (12) 28-31
I consider it a privilege and pleasure to address this, the tenth meeting of the Pacific Seabird Group. I have divided my talk into three parts. In the first I will give details as to how and why the group was formed and tell you about some of those who...
Effect of ACTH on plasma corticosterone and cortisol in eagles and condors
R.D. Zenoble, R.J. Kemppainen, D.W. Young, J. W. Carpenter
1985, Journal of the American Veterinary Medical Association (187) 1119-1120
The effect of ACTH on plasma corticosterone and cortisol was determined in 12 eagles (Haliaeetus leucocephalus) and in 6 Andean condors (Vultur gryphus). In all raptors, the concentration of plasma corticosterone was substantially greater than that of cortisol. After ACTH administration, the eagles had a marked increase (P less than...
Shiny cowbird parasitism in two avian communities in Puerto Rico
J. W. Wiley
1985, Condor (87) 165-176
The shiny cowbird (M. bonariensis), a brood parasite, has recently expanded its range from South America to Puerto Rico via the Lesser Antilles. This species is a host generalist and, on reaching Puerto Rico, encounteed avian species with no history of social parasitism. In mangrove habitat study areas, 42% of...
