Pup production, abundance, and breeding distribution of northern elephant seals at San Nicolas Island, winter 1981
1985, California Fish and Game (71) 53-55
A major breeding colony of northern elephant seals, Mirounga angustirostris, occurs on San Nicolas Island, California. Due to commercial hunting, elephant seals were extinct on San Nicolas Island by the end of the 19th century. Subsequent recovery of the population has been well documented (Table 1). Census data...
Geologic evolution of the United States Atlantic Margin
C. W. Poag
1985, Book
This volume compiles the significant findings which began to be accumulated in 1974 during offshore petroleum explorations in the Atlantic Continental Shelf. It's the first presentation of current geological data from the U.S. Atlantic Margin from the inner edge of the coastal plain to the deep sea. A seismic grid...

Equivalent radiolarian ages from ophiolitic terranes of Cyprus and Oman
Charles D. Blome, William P. Irwin
1985, Geology (13) 401-404
Radiolarian biostratigraphy shows that umberiferous strata overlying the Troodos ophiolite in Cyprus are Turonian in age and are thus essentially contemporaneous with similar strata that overlie the Samail ophiolite in Oman. However, this radiolarian age is markedly older than Campanian isotopic ages measured on the underlying rocks of the Troodos...
An investigation of hydraulic conductivity estimation in a ground-water flow study of Northern Long Valley, New Jersey
Mary C. Hill
1985, Thesis
The purpose of this study was to develop a methodology to be used to investigate the aquifer characteristics and water supply potential of an aquifer system. In particular, the geohydrology of northern Long Valley, New Jersey, was investigated. Geohydrologic data were collected and analyzed to characterize the site. Analysis was...

Population biology of bluegills, Lepomis macrochirus, in lotic habitats on the irrigated San Joaquin Valley floor
M. K. Saiki, C. J. Schmitt
1985, California Fish and Game (71) 225-244
Rapid expansion of irrigated agriculture in the western United States has prompted concerns for aquatic resources. Although the impacts of irrigation activities on quality and quantity of river water are well documented (e.g., high turbidity from soil erosion, eutrophication from nutrient runoff, pesticide contamination, reduced dis- charge), their effects on...

A plate flexure approximation to postseismic and interseismic deformation
James C. Savage, Guohua Gu
1985, Journal of Geophysical Research B: Solid Earth (90) 8570-8580
The rather large postseismic deformation that is associated with two‐dimensional dip‐slip faulting in the lithosphere is related to the bending of a free plate generated by dip‐slip faulting. In the absence of gravity, asthenosphere relaxation eventually permits the faulted lithosphere to assume the dihedral configuration of a faulted free plate....
Carbon, oxygen and hydrogen isotope abundances inStylites reflect its unique physiology
Leonel d.S.L Sternberg, Michael J. DeNiro, D. McJunkin, R. Berger, Jon E. Keeley
1985, Oecologia (67) 598-600
Natural abundances of oxygen-18, carbon-14, carbon-13 and deuterium were measured inStylites andicola, a terrestrial vascular plant lacking stomates, and two terrestrial plant species having stomates that grew nearby. No substantial differences in oxygen-18 and carbon-13 abundances were observed among the three species. The deuterium concentration inStylites was much higher than in...
An evaluation of uranium-series dating of fossil echinoids from southern California Pleistocene marine terraces
Daniel R. Muhs, George L. Kennedy
1985, Marine Geology (69) 187-193
Fossil sea urchins (Strongylocentrotus) from Pleistocene marine terraces on the southern California Channel Islands have been dated by the uranium-series method in order to test the suitability of echinoids for dating marine terraces. Results indicate that urchin plates and spines do not behave as closed systems with respect to both...

Determining age and sex of American coots
William R. Eddleman, Fritz L. Knopf
1985, Journal of Field Ornithology (56) 41-55
Reliable techniques for age and sex determination of migrating and wintering American Coots (Fulica americana) have not been available. Breeding coots can be ages through age 3 by tarsal color (birds 4 years and older were placed in a 4+ age class) (Crawford 1978), and males and females have...
Plant water status relationships among major floodplain sites of the Flathead River, Montana
L.C. Lee, T.M. Hinckley, M. L. Scott
1985, Wetlands (5) 15-34
Water status measurements of dominant species from major floodplain plant community types of the North Fork Flathead River, Montana were used to test the accuracy of site moisture gradient relationships postulated from floristic ordinations and site water balance estimates. Analysis of variance tests showed significant differences among the average predawn...
Influence of various land uses on windbreak selection by nesting Mississippi kites
Diane Love, Joseph A. Grzybowski, Fritz L. Knopf
1985, The Wilson Bulletin (97) 561-565
Contemporary land-use practices have dramatically altered breeding habitats of birds of prey (Cramp, pp. 9-11 in World Conf. Birds of Prey, R. D. Chancellor, ed., ICPB, London, England, 1977). Some land uses appear to influence strongly both the nesting activity (White, Trans. North Am. Wild. Nat. Resour. Conf. 39:301-312,...
Interspecific relationships between American coots and waterfowl during fall migration
William R. Eddleman, Craig T. Patterson, Fritz L. Knopf
1985, The Wilson Bulletin (97) 463-472
Interactions between American Coots (Fulica americana) and water-fowl during the breeding season are well-documented (Ryder 1959, Nudds 1981). Ducks and coots use similar nesting, feeding, brooding, and loafing sites during the breeding season (Munro 1939, Sooter 1945, Ryder 1959). Coots create potential nest sites, repulse predators, provide predation...
A relational approach to vector data structure conversion
Jan W. van Roessel, Eugene A. Fosnight
1985, Conference Paper, Auto-Carto VII: Proceedings of the digital representations of spatial knowledge
The proliferation of geographic information systems and digital data bases is creating a need for efficient methods to convert data from one spatial data structure to another. One approach is to create ad hoc interfaces, with a potential of N(N-1) interfaces for N data structures. Using an intermediate data structure,...

Devonian eustatic fluctuations in Euramerica
J.G. Johnson, Gilbert Klapper, Charles Sandberg
1985, GSA Bulletin (96) 567-587
The Devonian System of Euramerica contains at least 14 transgressive-regressive (T-R) cycles of eustatic origin. These are separated into three groups (or depophases) and from Carboniferous cycles by three prominent regressions. Twelve post-Lochkovian T-R cycles are recognized, and they commonly appear to result from abrupt deepening events followed by prolonged...
16th century European earthquakes described in some contemporary woodcuts
H. Deresiewicz
1985, Earthquake Information Bulletin (USGS) (17) 204-210
In the middle of the 15th century, shortly after Gutenberg’s invention of printing using individual lead type, the first illustrated broadsides (or broadsheets) began appearing in southern Germany. Usually printed on one side of a sheet of paper, they consisted of a woodcut illustration, sometimes colored, either by hand or...
