Effect of illite particle shape on cesium sorption
Pavol Rajec, Vladimir Sucha, Dennis D. Eberl, Jan Srodon, Francoise E. Elsass
1999, Clays and Clay Minerals (47) 755-760
Samples containing illite and illite-smectite, having different crystal shapes (plates, “barrels”, and filaments), were selected for sorption experiments with cesium. There is a positive correlation between total surface area and Cs-sorption capacity, but no correlation between total surface area and the distribution coefficient, Kd. Generally Kd increases with the edge...

Syngenetic Au on the Carlin trend: Implications for Carlin-type deposits
P. Emsbo, R.W. Hutchinson, A. H. Hofstra, J.A. Volk, K. H. Bettles, G.J. Baschuk, C. A. Johnson
1999, Geology (27) 59-62
A new type of gold occurrence recently discovered in the Carlin trend, north-central Nevada, is clearly distinct from classic Carlin-type gold ore. These occurrences are interpreted to be of sedimentary exhalative (sedex) origin because they are stratiform and predate compaction and lithification of...

1999, Photogrammetric Engineering and Remote Sensing (65) 1021-1032
The international Geosphere Biosphere Programme (IGBP) has called for the development of improved global land-cover data for use in increasingly sophisticated global environmental models. To meet this need, the staff of the U.S. Geological Survey and the University of Nebraska-Lincoln developed and applied a global land-cover characterization methodology using 1992-1993...
The adrenocorical stress-response of Black-legged Kittiwake chicks in relation to dietary restrictions
A.S. Kitaysky, John F. Piatt, J.C. Wingfield, M. Romano
1999, Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology (169) 303-310
In this study we examined hormonal responses of Black-legged Kittiwake (Rissatridactyla) chicks to experimental variations in energy content and nutritional quality (low or high lipid to protein ratio, LPR) of their food. Starting at the age of 10 days, chicks were fed either high or low LPR fish at...
Defining landscapes suitable for restoration of grizzly bears Ursus arctos in Idaho
Troy Merrill, D.J. Mattson, R.G. Wright, Howard B. Quigley
1999, Biological Conservation (87) 231-248
Informed management of large carnivores depends on the timely and useful presentation of relevant information. We describe an approach to evaluating carnivore habitat that uses pre-existing qualitative and quantitative information on humans and carnivores to generate coarse-scale maps of habitat suitability, habitat productivity, potential reserves, and areas of potential conflict....
