Occurrence of whirling disease of trout in western United States
H. Wolf, W. T. Yasutake
1970, Journal of the Fisheries Research Board of Canada (27) 955-956
Whirling disease of trout, caused by Myxosoma cerebralis, was diagnosed in 1966 for the first time in rainbow trout (Salmo gairdneri) from California and Nevada hatcheries. In 1969 the first incidence of this disease in cutthroat trout (S. clarki) was reported in Nevada. To date these have been the only confirmed cases...
The demography of the lizard, Uta stansburiana Baird and Girard, in southern Nevada
F.B. Turner, G.A. Hoddenbach, P.A. Medica, J.R. Lannom
1970, Journal of Animal Ecology (39) 505-519
Between 1966 and 1967 populations of Uta stansburiana in southern Nevada increased about 40%. Over the next year they declined by about 50%. These changes are explained in terms of annual differences in fecundity and survival. Most females laid five clutches of...
Fin degeneration of young-of-the-year Alosa pseudoharengus (Clupeidae) in southern Lake Michigan
Edward H. Brown Jr., Carroll R. Norden
1970, Copeia (1970) 766-769
Young-of-the-year alewives, Alosa pseudoharengus, with extremely shortened caudal fins were observed at four locations in southern Lake Michigan between 1964 and 1968. Some of the fins appeared stunted or underdeveloped, but microscopic examination revealed a deterioration of the fins and not an ontogenetic abnormality. Deterioration of the caudal fin was...
Concentrations of trace elements in Great Lakes fishes
Henry F. Lucas Jr., David N. Edgington, Peter J. Colby
1970, Journal of the Fisheries Research Board of Canada (27) 677-684
The concentration of 15 trace elements was determined by activation analysis of samples of whole fish and fish livers from three of the Great Lakes: Michigan, Superior, and Erie. The average concentrations of 7 elements in 19 whole fish from 3 species were as follows: uranium, 3ppb (parts per billion);...

Toxicity of 33NCS (3'-chloro-3-nitrosalicylanilide) to freshwater fish and sea lampreys
Leif L. Marking, Everett L. King, Charles R. Walker, John H. Howell
1970, Investigations in Fish Control 38
The chemical 33NCS (3'-chloro-3-nitrosalicylanilide) was evaluated as a fish control agent and as a larvicide for sea lampreys at the Fish Control Laboratories of the Bureau of Sport Fisheries and Wildlife and the Hammond Bay Biological Station of the Bureau of Commercial Fisheries. The chemical is rapidly toxic to many...

Waterfowl in relation to land use and water levels on the Spring Run Area
Gary L. Krapu, D.R. Parsons, M.W. Weller
1970, Iowa State Journal of Science (44) 437-452
Low water levels during critical phases of the breeding cycle appear to have caused population declines of waterfowl and other marsh birds on the Spring Run Game Management Area. Pair-counts indicated a decline from 70 pairs of waterfowl in 1965 to 2 pairs in 1968. Nest success of upland nesting...
A new technique for pumping hydrogen gas
I. Friedman, K. Hardcastle
1970, Geochimica et Cosmochimica Acta (34) 125-126
A system for pumping hydrogen gas without isotopic fractionation has been developed. The pump contains uranium metal, which when heated to about 80°C reacts with hydrogen to form UH3. The UH3 is heated to above 500°C to decompose the hydride and regenerate the hydrogen....
Remote Sensor Application Studies Progress Report, July L, 1968 to June 30, 1969. Controlled Field Experiments
L. C. Rowan, Terry W. Offield, R. D. Watson, P. J. Cannon, H.J. Grolier, H. A. Pohn, Kenneth Watson
1970, Report
Field Sites have been selected for controlled experiments to analyze physical and chemical parameters affecting the response of electromagnetic radiation to geological materials. Considerations in the selection of the sites are the availability of good exposures of nearly monomineralic rocks, level of geologic understanding, and ease of access. Seven sites,...
Winds over saltcedar
T. E. A. Van Hylckama
1970, Agricultural Meteorology (7) 217-233
An analysis of hourly wind speeds above and within a stand of saltcedar near Buckeye, Arizona, reveals that in 90% of all observed cases, the wind profiles above the stand can be represented by the simple logarithmic equation: uz=u*k1n">uz=u*k1n (zz0)">zz0) where...
Latitudinal gradients in tertiary molluscan faunas of the Pacific coast
W.O. Addicott
1970, Palaeogeography, Palaeoclimatology, Palaeoecology (8) 287-312
Tertiary molluscan faunas of the middle latitudes of the marginal eastern North Pacific are characterized by warm-water taxa whose descendants now live in more southerly latitudes. A series of profiles in which cumulative percentages of warm-water faunal elements are plotted against latitude show progressive northward decreases in the percentage of...
Static and kinetic friction of granite at high normal stress
J.D. Byerlee
1970, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (7) 577-582
Frictional sliding on ground surfaces of granite, angle of sliding planes 30° and 45°, was investigated as a function of confining pressure. Over the normal stress range of 2–12 kb, the static frictional shear stress τs follows the relationship τs = 0·5 + 0· σn and the kinetic frictional...
Foraminiferal zonation and carbonate facies of Carboniferous (Mississippian and Pennsylvanian) Lisburne group, central and eastern Brooks range, Arctic Alaska
Augustus K. Armstrong, Bernard L. Mamet, J. Thomas Dutro
1970, American Association of Petroleum Geologists Bulletin (54) 687-698
The Lisburne Group carbonate rocks of the central and eastern Brooks Range contain foraminiferal assemblages assigned to zones of late Tournaisian (Osage) to early Moscovian (Atoka) age. Representatives of both Eurasiatic and American cratonic microfaunas permit correlation with the original Carboniferous type sections in western Europe as well as with...

Chemotherapy of fish diseases: A review
R. L. Herman
1970, Journal of Wildlife Diseases (6) 31-34
Fish suffer from environmental, nutritional, viral, bacterial, parasitic, and neoplastic diseases, many of which are similar to those of higher animals. The prevention and treatment of these diseases follow the same principles as diseases of other animals. Fish culture is similar to poultry husbandry in that large numbers of animals...
Morphology of certain viruses of Salmonid Fishes. I. in vitro studies of some viruses causing Hematopoietic Necrosis
Donald F. Amend, Velma C. Chambers
1970, Journal of the Fisheries Research Board of Canada (27) 1285-1293
An electron microscope study was performed on three virus isolates that caused hematopoietic necrosis in salmonid fishes: infectious hematopoietic necrosis (IHN), Oregon Sockeye Disease (OSD), and Sacramento River Chinook Salmon Disease (SRCD). All three isolates were examined by negative staining of fathead minnow (FHM) monolayer tissue culture concentrates and IHN...
