An overview of raptor conservation in Latin America
D. H. Ellis, D.G. Smith
1986, Birds of Prey Bulletin (3) 21-25
Prior to the last decade, biological studies of raptorial birds in Latin America were almost nonexistent. For many species little more was known than their general range and habitat type. The last few years have seen the opening of a door to what will surely be a flood of scientific...
Habitat comparisons and productivity in nesting common terns on the mid-Atlantic coast
R.M. Erwin, D. C. Smith
1985, Colonial Waterbirds (8) 155-165
Nesting Common Terns (Sterna hirundo) were studied at a number of barrier beaches and small islands of tidal salt marsh in New Jersey and the Eastern Shore of Maryland-Virginina from 1980 through 1982. Data were collected on clutch sizes, nest spacing, and nesting success. The principal null hypothesis tested was...
Electrical geophysical investigations of massive sulfide deposits and their host rocks, West Shasta copper-zinc district
R. J. Horton, B. D. Smith, J.C. Washburne
1985, Economic Geology (80) 2213-2229
The West Shasta copper-zinc district, Shasta County, California, contains many volcanogenic sulfide deposits within Middle Devonian rhyolites that have not been highly metamorphosed. The district was selected by the U.S. Geological Survey for intensive geological, geochemical, and geophysical study under the Development of Assessment Techniques (DAT) project because accessible exposures...
Preliminary results of spectral induced polarization measurements, Wadi Bidah District, Kingdom of Saudi Arabia
Bruce D. Smith, C. L. Tippens, V. J. Flanigan, Hamdy Sadek
1983, Open-File Report 83-612
Laboratory spectral induced polarization (SIP) measurements on 29 carbonaceous schist samples from the Wadi Bidah district show that most are associated with very long polarization decays or, equivalently, large time constants. In contrast, measurements on two massive sulfide samples indicate shorter polarization decays or smaller time constants. This difference in...
