A repellent for protecting corn seed from blackbirds and crows
A.R. Stickley Jr., J.L. Guarineo
1972, Journal of Wildlife Management (36) 150-152
Methiocarb [4-(methylthio)-3,-5-xylyl N-methylcarbamate] was tested as a seed treatment for repelling blackbirds and crows (Corvus sp.) from sprouting corn in South Carolina. The test was conducted on eight fields within a 0.25-square-mile area. Marked repellency occurred; sprout damage averaged 44 percent in the control fields and 0.3 percent in the...

Production and standing crop of Hexagenia (Ephemeroptera) in a large reservoir
P.L. Hudson, G.A. Swanson
1972, Studies in Natural Sciences (1) 1-42
Population dynamics of the mayflies, Hexagenia limbata (Serville) and Hexagenia bilineata (Say), were studied in Lewis and Clark Lake from 1962 to 1969. Nymphs that hatched in June and July emerged as adults in 13-14 months (titled 1-year cycle) and nymphs hatched in late August or September emerged in 22...
Cloudburst floods in Utah, 1939-69
Elmer Butler, Ray E. Marsell
1972, Report
During 1939-69, 836 cloudburst floods were reported in Utah. The largest number was in 1965, when 88 floods were reported; 63 floods were reported in 1968, and 56 were reported in 1961. The smallest number of floods reported was three in 1944. In 1942, 1948, and 1950, six floods were...
Determination of total iodine and iodate in sea water and in various evaporites
M. M. Schnepfe
1972, Analytica Chimica Acta (58) 83-89
Iodine in sea water and evaporites is determined spectrophotometrically as the starch-iodine complex without prior separation or concentration of the iodine. In slightly alkaline solution, iodide is first oxidized to iodate with permanganate. Oxidized states of manganese are destroyed with iron(II) in phosphate medium...
Paleomagnetism of Midway Atoll lavas and northward movement of the Pacific plate

1972, Earth and Planetary Science Letters (17) 159-168
Two deep drill holes through the reef limestones of Midway Atoll penetrated 120 m and 19 m of basaltic lavas that were dated by the KAr method at 18 my. Inclinations of natural remanent magnetization have been measured...

1972, Archiv Fur Die Gesamte Virusforschung (39) 257-264
The morphology and ultrastructure of three North American salmonid pathogens, Oregon sockeye salmon, chinook salmon and infectious hematopoietic necrosis viruses, were examined by thin sectioning and negative staining after growth in fathead minnow cells at 10 ° C. The viruses matured at the plasma membrane of these cells. They were...

Duck hepatitis virus Interactions with DDT and dieldrin in adult mallards
Milton Friend, D.O. Trainer
1972, Bulletin of Environmental Contamination and Toxicology (7) 202-206
There has been considerable speculation regarding possible imteractlons within biological systems between synthetic environmental pollutants and infectious disease agents (1-11). This type of interaction has been studied in our laboratory using the mallard, Anas platyrhynchos, as a test species (5,6). Since adult ducks are refractory to the overt manifestations of...
Accumulation of dieldrin in an alga (Scenedesmus obliquus), Daphnia magna, and the guppy (Poecilia reticulata)
Robert E. Reinert
1972, Journal of the Fisheries Research Board of Canada (29) 1413-1418
Scenedesmus obliquus, Daphnia magna, and Poecilia reticulata accumulated dieldrin directly from water; average concentration factors (concentration in organism, dry weight, divided by concentration in water) were 1282 for the alga, 13,954 for D. magna, and 49,307 (estimated) for the guppy. The amount accumulated by each species at equilibrium (after about...
Feeding behavior of lake whitefish and lake herring in Torch Lake, Michigan

It is proposed that Haemoproteus nettionis (Johnston and Cleland, 1909) Coatney, 1936 be accepted as the correct name for the Haemoproteus of Anatidae. A list of synonyms and amended description of the parasite is given. Infections are reported from wood ducks (Aix sponsa) and from domestic ducks and geese, the...

1972, Book chapter, Progress in fishery and food science
This paper is a review of the sequence of events within the Great Lakes and their drainage to provide a basis for interpreting probable cause-and-effect relations between events of settlement and changes in the ecosystem of the Great Lakes. Possibilities of restoration of the lakes are discussed. A plan to...

Determination of channel capacity of the Mokelumne River downstream from Camanche Dam, San Joaquin and Sacramento Counties, California
R.G. Simpson
1972, Report
This study evaluates the adequacy of a 39-mile reach of the Mokelumne River in San Joaquin and Sacramento Counties, California, to carry planned flood releases between Camanche Reservoir and the Bensons Ferry Bridge near Thornton. The flood releases from Camanche Reservoir are to be restricted, insofar as possible, so that...
