M.J. Pavich, L. Brown, J. Harden, J. Klein, R. Middleton
1986, Geochimica et Cosmochimica Acta (50) 1727-1735
The distribution and residence time of cosmogenic 10Be in clay-rich soil horizons is fundamental to understanding and modelling the migration of 10Be on terrestrial sediments and in groundwater solutions. We have analyzed seven profiles of clay-rich soils developed from terrace sediments of the Merced River, California. The terraces and soils of increasing...

T. F. Kraemer, Y.K. Kharaka
1986, Geochimica et Cosmochimica Acta (50) 1233-1238
Formation water from U.S. Gulf Coast geopressured-geothermal sandstone aquifers has been analyzed to determine the geochemistry of uranium in these systems. Results of chemical analyses and chemical equilibrium modeling indicate the formation waters are in equilibrium with uraninite (UO2) and coffinite (USiO4). The 234U238U">234U238U activity ratios...

Frederic H. Wilson, James E. Case, Robert L. Detterman
1985, Circular 945
A zone of structural disruption and complexity along the Pacific coast margin of the Alaska Peninsula (fig. 41) may be related to the Alaska Peninsula and the Chugach terrane boundary. The best exposure of this zone is located on the east shore of Humpback Bay (figs. 42, 43; also Burk,...
Digital image processing techniques for detecting surface alteration - An application on the Alaska Peninsula: A section in The United States Geological Survey in Alaska: Accomplishments during 1983
James York, Frederic H. Wilson, Bruce M. Gamble
1985, Circular 945
The tectonic evolution of the Alaska Peninsula makes it a likely area for the discovery of significant mineral deposits. However, because of problems associated with remoteness and poor weather, little detailed mineral exploration work has been carried on there. This study focuses on using Landsat multispectral scanner data for the...

The need for accuracy in modelling: An example
Douglas H. Johnson, M.J. Conroy, J.D. Nichols
1985, Ecological Modelling (30) 157-161
The need for accurate information in modelling depends on the objectives of the effort. but trustworthy data are essential for a model intended for use in the management of natural resources. This point is illustrated by referring to a recently published model of canvasback ducks. We demonstrate that several key...
Goodness-of-fit tests for open capture-recapture models
K. H. Pollock, J.E. Hines, J.D. Nichols
1985, Biometrics (41) 399-410
General goodness-of-fit tests for the Jolly-Seber model are proposed. These tests are based on conditional arguments using minimal sufficient statistics. The tests are shown to be of simple hypergeometric form so that a series of independent contingency table chi-square tests can be performed. The relationship of these...
Interspecific competition among Hawaiian forest birds
Stephen Mountainspring, J. M. Scott
1985, Ecological Monographs (55) 219-239
The object of this study was to determine whether interspecific competition modified local geographic distribution, after taking into account the effect of habitat structure. The tendencies for 14 passerine birds to have positive or negative associations were examined, using 7861 sample points in seven native forests on the islands of...
A search for stability gradients in North American breeding bird communities
B.R. Noon, D.K. Dawson, J.P. Kelly
1985, The Auk (102) 64-81
To search for the existence of stability gradients in North American breeding land bird communities we operationally defined stability (after Jarvinen 1979) as year-to-year persistence in species composition and distribution of species abundances. From the census data for 174 study plots we derived nine indices that estimate the annual variability...

1985, Book chapter, Raptor Research Foundation Symposium on the Management of Birds of Prey. International Meeting. Session 5. Workshop: Experimental Design and Data Analysis for Telemetry Projects. November 1985,
Telemetry techniques can be used to study the survival rates of animal populations and are particularly suitable for species or settings for which band recovery models are not. Statistical methods for estimating survival rates and parameters of survival distributions from observations of radio-tagged animals will be described. These methods have...
Maximum likelihood methods for investigating reporting rates of rings on hunter-shot birds
M.J. Conroy
B.J.T. Morgan, P.M. North, editor(s)
1985, Book chapter, Statistics in Ornithology
It is well known that hunters do not report 100% of the rings that they find on shot birds. Reward studies can be used to estimate what this reporting rate is, by comparison of recoveries of rings offering a monetary reward, to ordinary rings. A reward study of American Black...
