Relation of mercury, uranium, and lithium deposits to the McDermitt caldera complex, Nevada-Oregon
James J. Rytuba, Richard K. Glanzman
1979, Papers on mineral deposits of western North America (Report 33) 109-117
The McDermitt caldera complex, located along the Nevada-Oregon border, is a Miocene collapse structure 45 km in diameter. Large-volume rhyolitic and peralkaline ash-flow tufts were erupted from 17.9-15.8 m.y. ago, leading to the formation of overlapping and nested calderas. Emplacement of rhyolitic ring domes, located primarily along the western margin...
Better utilization of ground water in the Piedmont and mountain region of the southeast
Ralph C. Heath
1979, Conference Paper, Water conservation and alternative water supplies: proceedings of a southeast regional conference
The development of water supplies for domestic consumption, and for those commercial and industrial uses requiring relatively pure water, has followed a pattern in the Piedmont and mountain areas of the southeast similar to that in most other humid areas. The first settlers utilized seepage springs on hillsides. Such springs...

1979, Report
The current energy crisis is affecting the lives of all Americans. Continued increases in energy prices and frequent shortages are stark reminders of our growing dependence on foreign energy resources in today's energy-hungry world. A comprehensive national energy policy must consider a variety of energy resources, including synfuels, to meet...

Toxicity of fishery chemicals to the asiatic clam, Corbicula manilensis
Jack H. Chandler, L. L. Marking
1979, Progressive Fish-Culturist (41) 148-151
The Asiatic clam (Corbicula manilensis), a species introduced into U. S. waters, has spread rapidly, and its ability to survive, reproduce, and spread has caused concern. Aquatic biologists suspect that the clams may crowd out indigenous mollusks, and the animals sometimes plug water intakes and leave shell deposits that interfere...
United States Geological Survey Yearbook, fiscal year 1978
Water Resources Division, U.S. Geological Survey
1979, Report
Fiscal year 1978 saw the U.S. Geological Survey continuing to perform its basic historical missions of collecting, analyzing, and disseminating information about the Earth, its processes, and its water and mineral resources. Classifying Federal lands and supervising lessee mineral extraction operations on those lands were also major Survey concerns during...
Parathion causes secondary poisoning in a laughing gull breeding colony
Donald H. White, Kirk A. King, C. A. Mitchell, E. F. Hill, T. G. Lamont
1979, Bulletin of Environmental Contamination and Toxicology (23) 281-284
Use of organophosphate insecticides as replacements for the more persistent organochlorine compounds has increased dramatically in recent years. Organophosphates are desirable for field application because they break down rapidly in the environment and do not persist in animal tissues (Stickel 1974). Nevertheless, certain organophosphates are extremely toxic to wildlife for...

Water quality of Livingston Reservoir on the Trinity River, southeastern Texas
Jack Rawson
1979, Texas Department of Water Resources Report 230
The concentrations of dissolved solids, chloride, and sulfate in Livingston Reservoir on the Trinity River in southeastern Texas usually average less than 250 mg/l (milligrams per liter), 40 mg/l, and 50 mg/l, respectively. The water is usually hard or moderately hard (61 to 180 mg/l as calcium carbonate). The concentrations...

Atlantic salmon embryos and fry: Effects of various incubation and rearing methods on hatchery survival and growth
Kenneth A. Leon, W.A. Bonney
1979, Progressive Fish-Culturist (41) 20-25
Significantly heavier fry of Atlantic salmon (Salmo salar) and greatly reduced mortality apparently resulted from the use of matrix substrates during egg incubation and alevin development. Salmon fry produced by this method fed readily and did not have the constricted yolk sacs that commonly occur when conventional rearing methods are used....
Environmental aspects of engineering geological mapping in the United States
Dorothy H. Radbruch-Hall
1979, Bulletin of the International Association of Engineering Geology (19) 351-358
Many engineering geological maps at different scales have been prepared for various engineering and environmental purposes in regions of diverse geological conditions in the United States.

Donald H. White
1979, Pesticides Monitoring Journal (12) 193-197
Organochlorine pesticide and PCB residues in starlings from 126 sites within the contiguous 48 states were monitored during fall 1976. The average nationwide level of DDE and PCBs has increased significantly since 1974, but the number of sites reporting PCB residues has decreased fivefold. Dieldrin residues have remained unchanged since...

L.F. Stickel
1979, Journal of Animal Ecology (48) 871-887
(1) The relationships between habitat change and house mouse populations were studied by monthly live trapping in a corn-wheat-hay rotation on a small Maryland farm. (2) Population density reached 53.0/ha in a wheat/hay field in October and 25.4/ha in corn in September. Populations increased by immigration as wheat or corn...
The light-footed clapper rail: An update
Cynthia A. Wilburn, Paul D. Jorgensen, Barbara W. Massey, Venita A. Basham
1979, American Birds (33) 251-215
A preliminary report on the Light-footed Clapper Rail, Rallus longirostris levipes, estimated a population of 500-750 birds in California (Wilbur, Am. Birds 28:868-870, 1974). Since then, additional work has been accomplished, most notably: (1) an intensive study of Carpinteria Marsh, Santa Barbara County, 1976-1977 (Basham); (2) a series of winter...
Status of the everglade kite in Florida--1968-1978
P.W. Sykes Jr.
1979, The Wilson Bulletin (91) 495-511
The population status of the Everglade Kite (Rostrhamus sociabils plumbeus) was studied in Florida from 1968 through 1978. Sixty-four nestlings (40% of known fledged young) were leg-banded with unique color combinations, and of these, 17.2% were seen 1 or more years after they were banded. Kites were capable of breeding...

Donald H. White
1979, Pesticides Monitoring Journal (13) 12-16
Organochlorine residues in wings of adult mallards and black ducks were monitored nationwide during the 1976-77 hunting season. DDE was found in all samples. Levels were unchanged since the 1972-73 collections in all migratory routes except the Pacific Flyway, in which residue levels declined significantly. Dieldrin levels had not changed...
