E.W. Schafer, L. L. Marking
1975, Journal of Wildlife Management (39) 807-811
The avian frightening agent, 4-aminopyridine (4AP), was tested on five avian and two fish species to assess the effects of long-term 4AP exposure to nontarget vertebrates. Adult bobwhites (Colinus virginianus), mourning doves (Zenaida macroura), and ring-necked pheasants (Phasianus colchicus) were fed diets containing 3 percent 4AP-treated cracked corn diluted with...
New tritium data on movement of groundwater in western Fresno County, California
Joseph Fairfield Poland, Gordon L. Stewart
1975, Water Resources Research (11) 716-724
Well waters along two traverse lines were sampled in 1963 and tested for tritium concentration. Haskell et al. [1966] estimated from the apparent thermonuclear tritium concentrations that groundwater had moved westward in the lower water‐bearing zone at a maximum velocity of 14–16.5 mi (23–27 km) in 9 yr. The maximum velocities...

G. L. Hoffman
1975, Journal of Wildlife Diseases (11) 505-507
Water contaminated by Myxosoma cerebralis was disinfected with ultraviolet irradition to control whirling disease. Irradiation at 18,000 microwatt seconds/cm2 (MWS/cm2) reduced infectivity of M. cerebralis by 31-86% and 27,650 MWS/cm3 reduced infectivity by 86-100%, even in the presence of a small amount of silt....

Earthquake shaking and damage to buildings
R.A. Page, W. B. Joyner, J.A. Blume
1975, Science (189) 601-608
Ground shaking close to the causative fault of an earthquake is more intense than it was previously believed to be. This raises the possibility that large numbers of buildings and other structures are not sufficiently resistant for the intense levels of shaking that can occur close to the fault. Many...

Early Ordovician gastropod opercula and epicontinental seas
Ellis L. Yochelson
1975, Journal of Research of the U.S. Geological Survey (3) 447-450
Collections made for some years from Lower Ordovician rocks by many geologists have established that the heavy calcareous operculum of the gastropod Ceratopea is almost never found associated with a shell and that commonly this operculum is secondarily silicified. Ceratopea may have lived in a stressed habitat and may have...
The effect of a fuel oil spill on benthic invertebrates and water quality on the Alaskan arctic slope, Happy Valley Creek near Sagwon, Alaska
Jon W. Nauman, Donald R. Kernodle

The influence of late Cenozoic stratigraphy on distribution of impoundment-related seismicity at Lake Mead, Nevada-Arizona
R. Ernest Anderson, R. L. Laney
1975, Journal of Research of the U.S. Geological Survey (3) 337-343
At Lake Mead, contrasts in permeability of upper Cenozoic sediments show a better correlation with irregularly distributed impoundment-related seismicity than do contrasts in structure. An evaluation of structures developed during the late Cenozoic fails to explain the erratic distribution of seismicity. An evaluation of the late Cenozoic stratigraphy, however, shows...

Detection and transmission of Infectious Hematopoietic Necrosis Virus in rainbow trout (Salmo gairdneri) was studied at a commercial trout hatchery. Transmission of virus was demonstrated via water, feed and contaminated eggs. If eggs from carrier females were incubated several weeks in virus-free water, the resulting fry did not become infected....
The distribution of seepage within lakebeds
M.S. McBride, H.O. Pfannkuch
1975, Journal of Research of the U.S. Geological Survey (3) 505-512
The mutual exchange of water between lakes and contiguous permeable ground-water bodies, which are thin relative to the diameter of the lakes, was modeled digitally. A significant rate of seepage was found to extend only a relatively short distance from shore, thus forming a narrow band around the lake's perimeter....
