National Pesticide Monitoring Program: Residues of organochlorine chemicals in freshwater fish, 1980–81
Christopher J. Schmitt, James L. Zajicek, M. A. Ribick
1985, Archives of Environmental Contamination and Toxicology (14) 225-260
The U.S. Fish and Wildlife Service analyzed residues of organochlorine chemicals in 315 composite samples of whole fish collected in 1980–81 from 107 stations nationwide as part of the National Pesticide Monitoring Program (NPMP). The mean concentrations of total DDT and allp,p′-ho-mologs exceptp,p′-DDT showed significant but...

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...
The Meshik Arc: An eocene to earliest miocene magmatic arc on the Alaska Peninsula
Frederic H. Wilson
1985, Alaska Division of Geological & Geophysical Surveys Professional Reports DGGS PR 88
The Meshik arc is herein defined to include Eocene to earliest Miocene volcanic and hypabyssal rocks and the associated Meshik and Stepovak Formations of the central Alaska Peninsula. Igneous rocks range from basalt to dacite and yielded K-Ar ages of 48 to 22 m.y. The Meshik arc is oriented along...
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...
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...
