Application of remote sensing techniques for appraising changes in wildlife habitat
Harvey K. Nelson, Albert T. Klett, John E. Johnston
1971, Conference Paper, International Workshop in Earth Resources Survey Systems
An attempt was made to investigate the potential of airborne, multispectral, line scanner data acquisition and computer-implemented automatic recognition techniques for providing useful information about waterfowl breeding habitat in North Dakota. The spectral characteristics of the components of a landscape containing waterfowl habitat can be detected with airborne scanners. By...

Biology of larval sea lampreys (Petromyzon marinus) of the 1960 year class, isolated in the Big Garlic River, Michigan, 1960-65
Patrick J. Manion, Alberton L. McLain
1971, Technical Report 16
The early life history of the sea lamprey, from hatching to the first capture of metamorphosed individuals, is described from observations on a known-age population isolated in a tributary of southern Lake Superior. The population had its origin in the spring of 1960, when 722 sea lampreys nearing spawning condition...
The white-crowned pigeon: A fruit-eating pigeon as a host for Trichomonas gallinae
R. M. Kocan, A. Sprunt IV
1971, Journal of Wildlife Diseases (7) 217-218
Trichomoniasis resulting from infection by Trichomonas gallinae was observed in 12 laboratory reared white-crowned pigeons (Columba leucocephala). A field survey of nestlings in the Florida Keys revealed a prevalence of 88% T. gallinae carriers but no evidence of trichomoniasis could be found among the wild birds....

An annotated bibliography of fauna and flora described from the Dockum Group of Triassic age in eastern New Mexico and West Texas
James C. Wright, Warren I. Finch
1971, Open-File Report 71-333
This annotated bibliography was prepared by Warren I. Finch from a rough copy compiled by the late James C. Wright in either late 1967 or early 1968 as an aid to his understanding of the stratigraphic distribution of uranium deposits in Triassic rocks of the Southern high Plains. He did...
Population biology of lake trout (Salvelinus namaycush) of Lake Superior before 1950
Gary T. Sakagawa, Richard L. Pycha
1971, Journal of the Fisheries Research Board of Canada (28) 65-71
Scale samples collected in 1948 were used to estimate the instantaneous total mortality rate (0.70) and growth for lake trout (Salvelinus namaycush) in Lake Superior before the population had been significantly reduced by the sea lamprey (Petromyzon marinus). Indirect evidence indicates that the instantaneous natural mortality rate was probably 0.10–0.25....
Determination of silver in soils, sediments, and rocks by organic-chelate extraction and atomic absorption spectrophotometry
T. T. Chao, J.W. Ball, H. M. Nakagawa
1971, Analytica Chimica Acta (54) 77-81
A useful method for the determination of silver in soil, sediment, and rock samples in geochemical exploration has been developed. The sample is digested with concentrated nitric acid, and the silver extracted with triisooctyl thiophosphate (TOTP) in methyl isobutyl ketone (MIBK) after dilution of the...
Paleomagnetism of San Cristobal Island, Galapagos
A. Cox
1971, Earth and Planetary Science Letters (11) 152-160
Isla San Cristobal, the most easterly of the Galapagos Islands, consists of two parts: a large volcano constitutes the southwest half of the island and an irregular apron of small cones and flows makes up the northeast half. As some of the...
A Pliocene flora and insect fauna from the Bering Strait region
D.M. Hopkins, J.V. Matthews, J. A. Wolfe, M.L. Silberman
1971, Palaeogeography, Palaeoclimatology, Palaeoecology (9) 211-231
A flood-plain forest has been preserved beneath a lava flow that invaded the Inmachuk River Valley in the northern part of the Seward Peninsula, Alaska, during the Pliocene Epoch. The fossil flora is of great biogeographic interest because of its position (Fig. 1)...
C13 and O18 compositions in some fresh-water carbonates associated with ultramafic rocks and serpentinites: Western United States
J. R. O’Neil, I. Barnes
1971, Geochimica et Cosmochimica Acta (35) 687-697
All carbonates associated with the ultramafic rocks and serpentinites of the western United States are shown by their stable isotope ratios to be of near-surface, low-temperature origin. These include vein materials that have been previously classified as hydrothermal. New laboratory and natural data...
Analytical sensitivities and energies of thermal neutron capture gamma rays II
F. E. Senftle, H.D. Moore, D.B. Leep, A. El-Kady, D. Duffey
1971, Nuclear Instruments and Methods (93) 425-459
A table of the analytical sensitivities of the principal lines in the thermal neutron capture gamma-ray spectrum from 0 to 3 MeV has been compiled for most of the elements. A tabulation of the full-energy, single-escape, and double-escape peaks has also been made...
Fluid inclusions in quartz crystals from South-West Africa

Quartz crystals from calcite veins of unknown age in Precambrian metasedimentary rocks at Geiaus No. 6 and Aukam farms in South-West Africa contain both primary and secondary inclusions filled with one or a variable combination of: organic liquid, moderately saline aqueous liquid, dark-colored...

Hydrogeochemical effects of injecting wastes into a limestone aquifer near Pensacola, Florida
Donald A. Goolsby
1971, Groundwater (9) 13-19
Acidic industrial wastes have been injected into deep wells in a limestone aquifer near Pensacola, Florida, since 1963. Prior geohydrologic studies in the area had indicated that the limestone aquifer contained nonpotable water and was overlain by an extensive clay confining layer.Two injection wells are presently being used to inject...

Analyses of uranium isotopes and their long-lived daughter products showed evidence of uranium migration in most of the 22 fossil mollusk shell samples from marine terrace deposits in southern California. Two samples, however, remained an ideal closed system as indicated by concordant230Th/234U...
Alewife dieoffs: Why do they occur?
Peter J. Colby
1971, Limnos (4) 18-27
Periodid midwinter, early spring, and summer mortalities of alewives (Alosa pseudoharengus) have been common in the Great Lakes since the first appearance of the silvery marine invader in Lake Ontario in the mid-1870's. In 1967 a nationally publicized dieoff of tremendous magnitude (estimated at several hundred million pounds of...
