Biochemical changes in longear sunfish, Lepomis megalotis, associated with lead, cadmium and zinc from mine tailings
F.J. Dwyer, C.J. Schmitt, S.E. Finger, P. M. Mehrle
1988, Journal of Fish Biology (33) 307-317
Longear sunfish were collected from a stream contaminated with mine tailings rich in lead (Pb), cadmium (Cd) and zinc (Zn). Blood samples were analysed for δ-aminolevulinic acid dehydratase (ALA-D) activity and Pb concentration. Vertebrae were tested for bone strength and composition, and Pb, Zn, and Cd concentrations were determined in...

New and revised lithostratigraphic units are recognized in northern New South Wales. New lithostatigraphic units are: Cara Formation, Whitlow Formation, Bobs Creek Formation, Nangahrah Formation, and Dinoga Formation. Revision of the Woolomin beds to Woolomin Group and Woodsreef Melange is proposed....

1988, Book chapter, The Atlantic Continental Margin
Presently, the continental margin of the southeastern United States (Fig. 1) forms a zone of transition between the actively building, steep-fronted carbonate platform of the Bahamas and the typical eastern North American terrigenous clastic-dominated, drowned, shelf-slope-rise configuration. This region of the continental margin is underlain by two major sedimentary basins—the...

Size differences in migrant sandpiper flocks: Ghosts in ephemeral guilds
J.L. Eldridge, Douglas H. Johnson
1988, Oecologia (77) 433-444
Scolopacid sandpipers were studied from 1980 until 1984 during spring migration in North Dakota. Common species foraging together in mixed-species flocks differed in bill length most often by 20 to 30 percent (ratios from 1.2:1 to 1.3:1). Observed flocks were compared to computer generated flocks drawn from three source pools...
A 250,000-year climatic record from Great Basin vein calcite: Implications for Milankovitch theory
Isaac J. Winograd, Tyler B. Coplen, Barney J. Szabo, Alan C. Riggs
1988, Science (242) 1275-1280
A continuous record of oxygen-18 (δ18O) variations in the continental hydrosphere during the middle-to-late Pleistocene has been obtained from a uranium-series dated calcitic vein in the southern Great Basin. The vein was deposited from ground water that moved through Devils Hole—an open fault zone at Ash Meadows, Nevada—between 50 and...
Book review of Wildlife 2000: Modeling relationships of terrestrial vertebrates, edited by J. Verner, M.L. Morrison, and C.J. Ralph
Robert J. Cooper
1988, The Wilson Bulletin (100) 697-699
"Wildlife 2000" is the proceedings of a conference held 7-11 October 1984, near Lake Tahoe, California, the objective of which was to present an up-to-date synthesis of models that predict the responses of wildlife to habitat change. This extremely attractive, well-produced volume has been well received by the wildlife...
Nonparametric statistical methods for comparing two sites based on data with multiple nondetect limits
Steven P. Millard, Steven J. Deverel
1988, Water Resources Research (24) 2087-2098
As concern over the effects of trace amounts of pollutants has increased, so has the need for statistical methods that deal appropriately with data that include values reported as “less than” the detection limit. It has become increasingly common for water quality data to include censored values that reflect more...
Age of native copper mineralization, Keweenaw Peninsula, Michigan
Theodore J. Bornhorst, James B. Paces, Norman K. Grant, J. Obradovich, N. King Huber
1988, Economic Geology (83) 619-625
Amygdaloidal flood basalts and conglomerates are the host for substantial deposits of native copper within the Portage Lake Volcanics in the Keweenaw Peninsula of Michigan. A wide variety of gangue minerals are associated with the regional hydrothermal alteration-mineralization event. Application of the Rb-Sr method to amygdule-filling microcline, calcite, epidote, and...

Magmatic heat and the El Niño cycle
H. R. Shaw, J.G. Moore
1988, Eos, Transactions, American Geophysical Union (69) 1553-1565
Large submarine lava flows with apparent volumes exceeding 10 km3 have recently been imaged on the deep ocean floor in various parts of the Pacific by means of GLORIA and SeaMarc side‐looking sonar surveys. Such flows may produce thermal anomalies large enough to perturb the cyclic processes of the ocean and...
Compositional zonation and cumulus processes in the Mount Mazama magma chamber, Crater Lake, Oregon
T. H. Druitt, Charles R. Bacon
1988, Earth and Environmental Science Transactions of The Royal Society of Edinburgh (79) 289-297
The 6845 ± 50 BP climactic eruption of Mount Mazama discharged 47 ± 9 km3 of vertically zoned calc-alkaline magma, affording a virtually complete section through the chamber. Evidence for two andesitic parents with different trace-element (particularly Sr) and water contents is preserved in the ejecta. Prior to eruption, a...
Antler anomalies in tule elk
Peter J.P. Gogan, David A. Jessup, Reginald H. Barrett
1988, Journal of Wildlife Diseases (24) 656-662
Antler anomalies were evident in tule elk (Cervus elaphus nannodes) within 1 yr of reintroduction to Point Reyes, California (USA). These anomalies are consistent with previously described mineral deficiency-induced anomalies in cervids. The elk were judged deficient in copper. Low levels of copper in soils and vegetation at the release...
Microbial degradation of crude oil and some model hydrocarbons
Fu-Hsian Chang, N.N. Noben, Danny Brand, Marc F. Hult
1988, Conference Paper, Proceedings of the Second Technical Meeting, Cape Cod, Massachusetts, October 21-25, 1985: U.S. Geological Survey Open-File Report 86-481
Research on microbial degradation of crude oil in the shallow subsurface at a spill site near Bemidji, Minn. (fig. C-l), began in 1983 (Hull, 1984; Chang and Ehrlich, 1984). The rate and extent of crude oil and model hydrocarbon biodegradation by the indigenous microbial community was measured in the laboratory...
Microbial transformations of azaarenes in creosite-contaminated soil and ground water: Laboratory and field studies
W. E. Pereira, C.E. Rostad, D.M. Updegraff, J.L. Bennett
1988, Water Science and Technology (20) 17-23
Azaarenes or aromatic nitrogen heterocycles are a class of compounds found in wood-preservative wastes containing creosote. The fate and movement of these compounds in contaminated aquifers is not well understood. Water-quality studies in an aquifer contaminated with creosote near Pensacola, Florida, indicated that ground water was contaminated with several azaarenes...

Geochemical and climatic effects of increased marine organic carbon burial at the Cenomanian/Turonian boundary
M.A. Arthur, W.E. Dean, L.M. Pratt
1988, Nature (335) 714-717
Perhaps the most significant event in the Cretaceous record of the carbon isotope composition of carbonate1,2, other than the 1–2.5 ‰ negative shift in the carbon isotope composition of calcareous plankton at the Cretaceous/Tertiary boundary3, is the rapid global positive excursion of ∼2 ‰ (13C enrichment) which took place between <span...
Evaluation of aerial transect surveys for wintering American black ducks
Michael J. Conroy, James R. Goldsberry, James E. Hines, Daniel B. Stotts
1988, Journal of Wildlife Management (52) 694-703
We used an experimental aerial transect survey with stratified random sampling, to estimate the size of the population of wintering black ducks (Anas rubripes) in coastal New Jersey during 2 winters, and the coastal Atlantic Flyway (Me. to S.C.) during 4 years. Population estimates were precise (CV < 0.20) on...
Pesticide contamination and hatching success of waterbirds in Mississippi
Donald H. White, W. James Fleming, Keren L. Ensor
1988, Journal of Wildlife Management (52) 724-729
Waterfowl wintering on the Yazoo National Wildlife Refuge (NWR) were contaminated (ltoreq 4 ppm wet wt) with dichloro diphenyl trichloroethane (DDT) and 1,1-dichloro-2,2-bis-(p-chlorophenyl) ethylene (DDE), but residues were below levels known to affect waterfowl. Eggs of some nesting waterbirds contained higher than expected levels of DDE, especially those of green-backed...
Distribution patterns of American black duck and mallard winter band recoveries
Duane R. Diefenbach, James D. Nichols, James E. Hines
1988, Journal of Wildlife Management (52) 704-710
We compared the distribution patterns of winter band recoveries of American black ducks (Anas rubripes) and mallards (A. platyrhynchos) banded in the same breeding areas. Young black ducks wintered northeast of young mallards but no differences in distribution patterns were detected between adult birds of the 2 species. Mallards exhibited...
