Aging small Canada geese by neck plumage
K.F. Higgins, L.J. Schoonover
1969, Journal of Wildlife Management (33) 212-214
The neck plumage method, a new technique for separating immature from adult Canada geese (Branta canadensis) in the hand, was evaluated by comparison with the notched tail feather and cloacal examination methods. Two (1.4 percent) of 141 geese examined were misaged, resulting in a 6 percent error in the immature-adult...
Devonian laterite in Chitral state, West Pakistan
Karl W. Stauffer
1969, Economic Geology (64) 452-454
A Devonian laterite has recently been discovered near Reshun in the Mastuj valley of Chitral State, West Pakistan. It is believed to be the fourth recorded Paleozoic laterite in the world. The laterite is entirely within a thick carbonate of the Shogram Formation of Upper Devonian (Frasnian) age. A chemical...
Compilation of hydrologic data, Green Creek, Brazos River basin, Texas, 1966
Trigg Twichell
1969, Report
In 1950 the U. S. Soil Conservation Service began construction of floodwater-retarding structures in Texas under authorities granted by the Congress. These authorities provide, where economically feasible, that the program be applied to tributary watersheds of 240,000 acres or less. The usual practice has been to control flood runoff from...
Compilation of hydrologic data, Honey Creek, Trinity River Basin, Texas, 1967
Trigg Twichell
1969, Report
The U.S. Soil Conservation Service is actively engaged in the installation of flood and soil erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found...
The circle creek rhyolite, a volcanic complex in northern Elko county, Nevada
Robert R. Coats
1968, Book chapter, Studies in Volcanology
The Circle Creek Rhyolite is a multiple-source mass of fayalite-ferro-augite rhyolite, forming an extensive complex in northern Elko County, Nevada, with a diameter of about 8 miles and an exposed area of about 36 square miles. From the structure of the flow layering and the complex sequence of microbrecciation structures,...
Developing a state water plan: Ground-water conditions in Utah, spring of 1968
R.M. Cordova, L.J. Bjorklund, R.G. Butler, R. W. Mower, L. R. Herbert, E.L. Bolke, G. W. Sandberg
1968, Cooperative Investigations Report 6
This report is the fifth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series are prepared cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources and are designed to provide data to enable interested parties such as legislators, administrators,...
Dissolved-mineral inflow to Great Salt Lake and chemical characteristics of the salt lake brine: Summary for water years 1960, 1961, and 1964
D. C. Hahl
1968, Utah Geological and Mineralogical Survey Water-Resources Bulletin 10
The investigation of dissolved-mineral inflow to Great Salt Lake during the water years 1960, 1961, and 1964 was conducted during conditions of streamflow that were representative of the lowest and the average recorded during the water years 1934-64. The study conducted during the 1960 and 1961 water years was limited...
Fluvial sediment in Utah, 1905-65: A data compilation
J. C. Mundorff
1968, Utah Division of Water Rights Information Bulletin 20
During the past 60 years, the characteristics of fluvial sediment in many streams in the Unites States have been studied by Federal agencies. The purpose of this report is to present available data – both published and unpublished – on fluvial sediment in Utah for the period 1905-65. (See figs....
An appraisal of the quality of surface water in the Sevier Lake basin, Utah, 1964
D. C. Hahl, J. C. Mundorff
1968, Technical Publication 19
The Sevier and Beaver River systems are the two major river systems in the Sevier Lake basin in Utah. This report contains an analysis of reconnaissance data collected during the 1964 water year regarding the quality of water in these rivers and their tributaries. The purpose of the reconnaissance was...
Extension of streamflow records in Utah
J.K. Reid, L.E. Carroon, G. E. Pyper
1968, Technical Publication 20
This report provides long-term data on streamflow at selected short-term gaging stations in Utah. The records of streamflow at the short-term or secondary gaging stations are extended on the basis of a graphical correlation with concurrent records at long-term or primary gaging stations. The data presented consist of records of...
Hydrologic reconnaissance of Skull Valley, Tooele County, Utah
James W. Hood, K.M. Waddell
1968, Technical Publication 18
This report is the second in a series by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights, which describes the water resources of the western basins of Utah. Its purpose is to present available hydrologic data on Skull Valley, to provide...
Dietary factors and hepatoma in rainbow trout (Salmo gairdneri). I. Aflatoxins in vegetable protein feedstuffs
R.O. Sinnhuber, J.H. Wales, J.L. Ayers, R.H. Engebrecht, D.F. Amend
1968, Journal of the National Cancer Institute (41) 711-718
Aflatoxins (toxic metabolites of the mold Aspergillus flavus) were present in a commercial trout ration causing hepatoma in rainbow trout. Cottonseed meal and solvent extracts of cottonseed meal and of rations containing cottonseed meal and peanut meal were found by chemical assay and confirmed by duckling assay to contain aflatoxins....
Some metabolic effects of bacterial endotoxins in salmonid fishes
Gary Wedemeyer, A. J. Ross, L. Smith
1968, Journal of the Fisheries Research Board of Canada (26) 115-122
Coho salmon (Oncorhynchus kisutch) and rainbow trout (Salmo gairdneri) were highly resistant to endotoxins from both Escherichia coli and Aeromonas salmonicida (a fish pathogen) at 14 and 18 C.This resistance was investigated with liver tryptophan pyrrolase, liver glycogen depletion in vitro, and the arterial blood pressure as indicators. Liver glycogen depletion...
Role of intestinal microflora in the degradation of DDT by rainbow trout (Salmo gairdneri)
G. Wedemeyer
1968, Life Sciences (7) 219-222
Though liver homogenates show apparent microsomal enzyme DDT-dehydrochlorinase activity, in the intact fish the intestinal microflora play a major role in DDT detoxication. Since the presence of this microflora in fish depends on the recent intake of food (12), the rate of detoxication and hence the toxicity of ingested DDT...
