Feeding ecology of breeding gadwalls on saline wetlands
J.R. Serie, G.A. Swanson
1976, Journal of Wildlife Management (40) 69-81
The feeding ecology of breeding gadwalls (Anas strepera) from saline wetlands in North Dakota was examined in relation to sex, pair mates, reproductive status, food availability, and wetland type during the spring and summer of 1971 and 1972. Esophagi of males and females contained 40.4 and 48.2 percent animal food,...
An acute septicaemic disease of brown trout (Salmo trutta) and Atlantic salmon (Salmo salar) caused by a Pasteurella-like organism
T. Hastein, G. L. Bullock
1976, Journal of Fish Biology (8) 23-26
Ulcerations of the skin associated with haemorrhagic petechiae of liver and kidneys, were the main signs of disease affecting salmon and brown trout in Norway. A death rate of 15–20% was estimated for the 5 month period of mid-March-August, although mortalities occurred throughout the year. Bacteriological examinations, involving 36 isolates,...
Teton Dam flood of June 1976, Menan Buttes quadrangle, Idaho
Cecil A. Thomas, Herman A. Ray, William A. Harenberg
1976, Hydrologic Atlas 570
The failure of the Teton Dam caused extreme flooding along the Teton River, Henrys Fork, and Snake River in southeastern Idaho on June 5-8, 1976. No flooding occurred downstream from American Falls Reservoir. The inundated areas and maximum water-surface elevations are shown in a series of 17 hydrologic atlases. The...
U-Th-Pb and Rb-Sr systematics of Allende and U-Th-Pb systematics of Orgueil
M. Tatsumoto, D.M. Unruh, G. A. Desborough
1976, Geochimica et Cosmochimica Acta (40) 617-634
U-Th-Pb systematics study of Allende inclusions showed that U, Th and Sr concentrations in Ca, Al (pyroxene)-rich chondrules and white and pinkish-white aggregate separates of Allende are five to ten times higher than those of the matrix, whereas Mg (olivine)-rich chondrules have U and Th concentrations about twice as high...
Carbon, hydrogen, and oxygen isotope studies of the regional metamorphic complex at Naxos, Greece
R. O. Rye, R.D. Schuiling, D.M. Rye, J.B.H. Jansen
1976, Geochimica et Cosmochimica Acta (40) 1031-1049
At Naxos, Greece, a migmatite dome is surrounded by schists and marbles of decreasing metamorphic grade. Sillimanite, kyanite, biotite, chlorite, and glaucophane zones are recognized at successively greater distances from the migmatite dome. Quartz-muscovite and quartz-biotite oxygen isotope and mineralogie temperatures range from 350 to 700°C.The metamorphic complex can be...

Constant potential pulse polarography
J. H. Christie, Larry L. Jackson, R. A. Osteryoung
1976, Analytical Chemistry (48) 561-564
The new technique of constant potential pulse polarography, In which all pulses are to be the same potential, is presented theoretically and evaluated experimentally. The response obtained is in the form of a faradaic current wave superimposed on a constant capacitative component. Results obtained with a computer-controlled system exhibit a...
Progress in remote sensing (1972-1976)
W. A. Fischer, W. R. Hemphill, Allan Kover
1976, Photogrammetria (32) 33-72
This report concerns the progress in remote sensing during the period 1972–1976. Remote sensing has been variously defined but is basically the art or science of telling something about an object without touching it. During the past four years, the major research thrusts have been in three areas: (1) computer-assisted enhancement and...
Aseismic uplift in Southern California
Robert O. Castle, Jack P. Church, Michael R. Elliot
1976, Science (192) 251-253
Preliminary examination of the historic geodetic record has disclosed crustal uplift of 0.15 to 0.25 meter that apparently began around 1960 and has since grown to include at least 12,000 square kilometers of southern California. This uplift extends at least 150 kilometers west-northwestward along the San Andreas Fault from Cajon...

Lunar nomenclature: A dissenting note
D.W.G. Arthur
1976, Icarus (27) 571-573
This note reviews the nature of the traditional (Mädler) lunar nomenclature and the recent developments based on the use of more than 2000 named provinces. It appears that the new nomenclature is less efficient than the old in many cases and may lead to an impossible publication situation. The unnecessary...

Allantoinase in the marine polychaete Eudistylia vancouveri
Dora R. M. Passino, G.W. Brown Jr.
1976, Experientia (32) 1376-1377
Allantoinase, an enzyme in the purine-urea cycle, was found in Eudistylia vancouveri (Polychaeta). The enzyme had a pH optimum at 7.6. The Km was 0.012 M allantoin, and the Arrhenius energy of activation was 12.6 to 14.6 kcal/mol....

Rapid determination of nanogram amounts of tellurium in silicate rocks
L. P. Greenland, E.Y. Campbell
1976, Analytica Chimica Acta (87) 323-328
A hydride-generation flameless atomic-absorption technique is used to determine as little as 5 ng g-1 tellurium in 0.25 g of silicate rock. After acid decomposition of the sample, tellurium hydride is generated with sodium borohydride and the vapor passed directly to a resistance-heated quartz cell mounted in an atomic-absorption spectrophotometer. Analyses...

Physiological response to hooking stress in hatchery and wild rainbow trout (Salmo gairdneri)
R.S. Wydoski, Gary Wedemeyer, N. C. Nelson
1976, Transactions of the American Fisheries Society (105) 601-606
This study evaluated the physiological response of rainbow trout to hooking stress after being played under standardized conditions (0–5 min) and estimated the time needed for recovery (to 72 h). Plasma osmolality and chloride measurements were used to evaluate osmoregulatory disturbances and gill ion-exchange function, and plasma glucose was used...
