Immunizing Canada geese against avian cholera
J.I. Price
1985, Wildlife Society Bulletin (13) 508-515
A small flock of captive giant Canada geese were vaccinated with the experimental bac- terin in Nebraska to test its efficacy under field conditions. Only 2 of 157 vaccinates died from avian cholera during an annual spring die-off....

MONITORING THE HYDROTHERMAL SYSTEM IN LONG VALLEY CALDERA, CALIFORNIA.
Christopher D. Farrar, Michael L. Sorey
1985, Conference Paper, Transactions - Geothermal Resources Council
An ongoing program to monitor the hydrothermal system in Long Valley for changes caused by volcanic or tectonic processes has produced considerable data on the water chemistry and discharge of springs and fluid temperatures and pressures in wells. Changes in hot spring chemistry that have been recorded probably relate to...
Invertebrate colonization rates in the tailwater of a Kentucky flood-control reservoir
W.D. Swink, J.F. Novotny
1985, Journal of Freshwater Ecology (3) 27-34
Invertebrate colonization on newly introduced rock substrates was examined from July through October 1982 in the tailwater of Barren River Lake, Kentucky. Chironomidae, the dominant taxon of benthic insects, reached full colonization by day 14. Colonization by Oligochaeta, the other major invertebrate taxon, was not completed by the end...
Niacin requirement for optimum growth, feed conversion and protection of rainbow trout, Salmo gairdneri Richardson, from ultraviolet-B irradiation
H. A. Poston, M.J. Wolfe
1985, Journal of Fish Diseases (8) 451-460
Triplicate groups of 75 rainbow trout, Salmo gairdneri Richardson, (mean weight 0–76 g) were fed a semipurified diet containing added niacinamide in amounts of 0.0, 1.25, 2.5. 5, 10, 20, 40, 80 or 160 mg/kg diet (ppm), for 16 weeks to determine the amount of niacinamide needed...
Maryland striped bass: Recruitment declining below replacement
C.P. Goodyear, J.E. Cohen, S.W. Christensen
1985, Transactions of the American Fisheries Society (114) 146-151
A mathematical technique was developed to examine interrelationships among first‐year survival rates, adult fecundity, and adult survival of striped bass Morone saxatilis based on indices of year‐class strength. Application of this technique to striped bass in Maryland waters of the Chesapeake Bay provided evidence for reduced survival in the life...
Improving waterfowl production estimates: Results of a test in the prairie pothole region
P.M. Arnold, L.M. Cowardin
1985, International Congress of Game Biologists (17) 859-865
The U.S. Fish and Wildlife Service in an effort to improve and standardize methods for estimating waterfowl production tested a new technique in the four-county Arrowwood Wetland Management District (WMD) for three years (1982-1984). On 14 randomly selected 10.36 km2 plots, upland and wetland habitat was mapped, classified, and digitized....
Histopathology associated with pyridoxine deficiency in Atlantic salmon (Salmo salar)
Roger L. Herman
1985, Aquaculture (46) 173-177
Fingerling Atlantic salmon (Salmo solar) fed a production diet deficient in pyridoxine showed several significant effects: increased mortality; behavioral changes; degenerative changes in kidneys, ovaries, and liver; a paucity of thyroid colloid; and hyperplasia of renal hematopoietic tissue. Changes in nerve tissue were equivocal....
PROGRESS REPORT ON GEOLOGIC STUDIES OF THE RANGER OREBODIES, NORTHERN TERRITORY, AUSTRALIA.
J. Thomas Nash, David Frishman
Sibbald T.I.I.Petruk William, editor(s)
1985, Conference Paper, CIM Special Volume
The Ranger No. 1 and No. 3 orebodies contain about 124,000 tonnes U//3O//8 in highly chloritized metasediments of the lower Proterozoic Cahill Formation within about 500 m of the projected sub-Kombolgie Formation unconformity. In both orebodies, oxidized and reduced uranium minerals occur chiefly in quartzose schists that have highly variable...
The complex variable boundary element method: Applications
T. V. Hromadka II, C.C. Yen, G. L. Guymon
1985, International Journal for Numerical Methods in Engineering (21) 1013-1025
The complex variable boundary element method (CVBEM) is used to approximate several potential problems where analytical solutions are known: A modelling result produced from the CVBEM is a measure of relative error in matching the known boundary condition values of the problem. A CVBEM error-reduction...
PRELIMINARY EVALUATION OF LANDSAT-4 THEMATIC MAPPER DATA FOR THEIR GEOMETRIC AND RADIOMETRIC ACCURACIES.
M.H. Podwysoki, N. Falcone, L.U. Bender, O. D. Jones
Barker John L., editor(s)
1985, Conference Paper, NASA Conference Publication
This report describes results of some preliminary analyses of Landsat-4 Thematic Mapper data for the NASA Landsat Image Quality Analysis program. The work is being done under interagency agreement S-12407-C between the U. S. Geological Survey and NASA-Goddard Space Flight Center. Landsat-4 TM scenes for Washington, D. C. Macon, Georgia...
