1986, Copeia (1986) 1024
We discovered a hermaphrodite Liopsetta glacialis while examining tissues from a sample of 30 representatives of this species for a histopathological survey of fishes from the Beaufort Sea, Alaska. L. glacialis occurs in the Arctic Ocean from Queen Maude Gulf in arctic Canada, along the North American and Siberian coasts to the...

Hydrogeology and ground-water use and quality, Brown County, Wisconsin
J. T. Krohelski, B.A. Brown
1986, Wisconsin Geological & Natural History Survey Information Circular 57
The Paleozoic rock of Brown County includes formations of Cambrian, Ordovician, and Silurian age. These formations are eastward-dipping sedimentary rock that rest on Precambrian crystalline rock and are overlain by Pleistocene deposits. The units that are the principal sources of ground water were grouped into three aquifers (upper, St. Peter,...
Powder X-ray diffraction of florencite-(Nd)
J. Fitzpatrick
1986, Powder Diffraction (1) 330-330
Florencite-(Nd) [(Nd,Ce)Al3(PO4)2(OH)6], was first described by Milton and Bastron (1971) from fracture surfaces in weathered cherts of the Franciscan Complex, south of Sausalito in Marin County, California. Florencite-(Nd) occurred there as a moderate-brown pulverulent earthy material; individual crystals were not discernible under microscopic examination. A semi-quantitative...

Geohydrology of the Vamoosa-Ada aquifer east-central Oklahoma with a section on chemical quality of water
Joseph J. D’Lugosz, Roger G. McClaflin, Melvin V. Marcher
1986, Circular 87
The Vamoosa-Ada aquifer, which underlies an area of about 2,320 mi2, consists principally of the Vamoosa Formation and the overlying Ada Group of Pennsylvanian age. Rocks comprising the aquifer were deposited in a nearshore environment ranging from marine on the west to nonmarine on the east. Because of changes in...
Water resources inventory of Connecticut Part 9: Farmington River basin
Elinor H. Handman, F. Peter Haeni, Mendall P. Thomas
1986, Connecticut Water Resources Bulletin 29
The Farmington River basin covers 435 square miles in north-central Connecticut upstream from Tariffville and downstream of the Massachusetts state line. Most water in the basin is derived from precipitation, which averages 48 inches (366 billion gallons) per year. An additional 67 billion gallons of water per year enters the...
Topographic maps
Theodore D. Steger
1986, Report
A topographic map is a line-and-symbol representation of natural and selected man-made features of a part of the Earth's surface plotted to a definite scale. A distinguishing characteristic of a topographic map is the portrayal of the shape and elevation of the terrain by contour lines....
Energy budget and prey requirements of breeding lapland longspurs Calcarius lapponicus near Barrow Alaska, U.S.A.
T. W. Custer, R. G. Osborn, F.A. Pitelka, J.A. Gessaman
1986, Arctic and Alpine Research (18) 415-428
Breeding Lapland longspurs, Calcarius lapponicus, near Barrow, Alaska, have relatively constant energy demands throughout the summer; the average estimated daily energy budgets (DEBs) were 132 and 118 kJ for the male and female. Thermoregulation accounted consistently for one-quarter to one-third of the total DEB. Flight in the male and incubation...
Effect of injected rotenone on the production and composition of urine from the rainbow trout (Salmo gairdneri)
D.A. Erickson, W.H. Gingerich
1986, Aquatic Toxicology (9) 263-274
Renal function was evaluated in adult rainbow trout (Salmo gairdneri) dosed i.a. with rotenone at 225 and 275 μg/kg. The chemical composition of urine samples and urine flow rates collected over a 5-h pretreatment period were compared with hourly urine samples collected over a 5-h posttreatment period. Significant increases in...
Liquid chromatography of hydrocarbonaeous quaternary amines on cyclodextrin bonded silica
S. L. Abidi
1986, Journal of Chromatography (362) 33-46
Mixtures of n-alkylbenzyldimethylammonium chloride (ABDAC) were resolved into homologous components by high-performance liquid chromatography (HPLC) with a cyclodextrin-bonded silica stationary phase. With a few exceptions, results from this study are similar to those obtained from traditional reversed-phase HPLC. It was found that the presence of electrolytes in aqueous mobile phases is not...

Persistence of rotenone in ponds at different temperatures
P.A. Gilderhus, J. L. Allen, V. K. Dawson
1986, North American Journal of Fisheries Management (6) 129-130
Two ponds were treated with liquid rotenone (5% rotenone), one with 3 mg/L at 24°C and the other with 2 mg/L at 0°C (concentrations of active rotenone were 0.15 and 0.10 mg/L, respectively). Water samples were collected and analyzed by high-performance liquid chromatography. The concentration of rotenone declined to 0.02...
Direct conversion of terpenylalkanolamines to ethylidyne N-nitroso compounds
S. L. Abidi
1986, Journal of Organic Chemistry (51) 2687-2694
A series of mono- and diterpenylalkanolamines bearing isopropylidene functionality on the terpene group was reacted with sodium nitrite in aqueous acetic acid to yield ethylidyne N-nitroso analogues. The key feature of this direct conversion involved initial N-nitrosation followed by apparent elimination of a "CH4" unit (not necessarily methane) from the...

Dynamics of alewives in Lake Ontario following a mass mortality
Robert O’Gorman, Clifford P. Schneider
1986, Transactions of the American Fisheries Society (115) 1-14
The U.S. Fish and Wildlife Service and the New York Department of Environmental Conservation assessed the population of alewives Alosa pseudoharengus in U.S. waters of Lake Ontario during 1976–1982 with bottom trawls. Alewives were abundant in 1976 but a die-off greatly reduced their numbers during the winter of 1976–1977. The...

A kinematic model of southern California
R. Weldon, E. Humphreys
1986, Tectonics (5) 33-48
We propose a kinematic model for southern California based on late Quaternary slip rates and orientations of major faults in the region. Internally consistent motions are determined assuming that these faults bound rigid blocks. Relative to North America, most of California west of the San Andreas fault is moving parallel...
The relationship between body mass and survival of wintering canvasbacks
G.M. Haramis, J.D. Nichols, K. H. Pollock, J.E. Hines
1986, The Auk (103) 506-514
Mass and recapture histories of 6,000 Canvasbacks (Aythya valisineria) banded in upper Chesapeake Bay were used to test two hypotheses: (1) early-winter body mass is associated with the probability of surviving the winter, and (2) early-winter body mass is associated with annual survival probability. Data were analyzed by a binary...

H. M. Ohlendorf, S. Harrison
1986, Environmental Pollution (Series B) (11) 169-191
Eggs of three representative species of seabirds (wedge-tailed shearwater Puffinus pacificus; red-footed booby Sula sula; and sooty tern Sterna fuscata) were collected in 1980 to determined differences in heavy metal, Se, and organochlorine residues among species nesting in the Hawaiian Archipelago and among the four nesting sites sampled (Oahu, French Frigate Shoals, Laysan,...
Analysis of utilization of desert habitats with dynamic simulation
B. Kenneth Williams
1986, Journal of Environmental Management (23) 1-18
The effects of climate and herbivores on cool desert shrubs in north-western Utah were investigated with a dynamic simulation model. Cool desert shrublands are extensively managed as grazing lands, and are defoliated annually by domestic livestock. A primary production model was used to simulate harvest yields and shrub...
