Stable isotopes in mineralogy
J. R. O’Neil
1977, Physics and Chemistry of Minerals (2) 105-123
Stable isotope fractionations between minerals are functions of the fundamental vibrational frequencies of the minerals and therefore bear on several topics of mineralogical interest. Isotopic compositions of the elements H, C, O, Si, and S can now be determined routinely in almost any mineral. A summary has been made of...
A digital file of the lunar normal Albedo
R.L. Wildey
1977, The Moon (16) 231-277
A digital file of the normal albedo of the Moon has been produced at a resolution of about 1/550 of a lunar diameter (about 6.3 km). The file was produced from five photographs taken with the 61-cm reflector of the Northern Arizona University Astrophysical Observatory. No mosaicking was necessary. Spatial...

Effects of tide cycles on habitat selection and habitat partitioning by migrating shorebirds
J. Burger, M.A. Howe, D.C. Hahn, J. Chase
1977, The Auk (94) 743-758
We studied assemblages of feeding shorebirds in three intertidal habitats on the coast of New Jersey during August to document how species segregate spatially both among and within habitats and to determine the effects of tidal cycles on these patterns. The habitats were a sandy beach facing the ocean proper...
A comparison of 2 techniques for estimating deer density
G.L. Storm, D.F. Cottam, R.H. Yahner, J.D. Nichols
1977, American Birds (31) 197-203
We applied mark-resight and area-conversion methods to estimate deer abundance at a 2,862-ha area in and surrounding the Gettysburg National Military Park and Eisenhower National Historic Site during 1987-1991. One observer in each of 11 compartments counted marked and unmarked deer during 65-75 minutes at dusk during 3 counts in...

1977, Condor (79) 275-278
Serum proteins from nine subspecies of Canada Geese (Brunta canadensis) were analyzed through the use of column and slab acrylamide electrophoresis. Variation was minimal within a subspecies, although all the subspecies were closely related. B. c. leucopareia appeared to be the most distinct subspecies, while maxima and moffitti were...

Kirk A. King, Edward L. Flickinger, H. H. Hildebrand
1977, Southwestern Naturalist (21) 417-431
Before 1920, native populations of brown pelicans (Pelecanus occidentalis carolinensis) were estimated at 50,000 to 85,000 birds in Louisiana and 5,000 in Texas. By 1958, brown pelicans had vanished from two wintering areas in each state, and wintering and breeding birds disappeared from additional areas between 1959 and 1961. By...

1977, Pesticides Monitoring Journal (11) 40-53
Shells of brown pelican (Pelecanus occidentalis) eggs collected in South Carolina from 1969 through 1973 were significantly thinner than shells of those collected before 1947. Residues of 10 organochlorine pollutants and 10 heavy metals were found in these eggs. Total organochlorine residues were apparently magnified 23 times from fish to...
Responsiveness of 6 to 14 generations of birds to dietary dieldrin toxicity
E. F. Hill, J. W. Spann, J.D. Williams
1977, Toxicology and Applied Pharmacology (42) 425-431
The lethal dietary toxicity of dieldrin was estimated repeatedly during 8 years of testing young bobwhites (Colinus virginianus), Japanese quail (Coturnix c. japonica), ring-necked pheasants (Phasianus colchicus), and mallards (Anas platyrhynchos). Toxicities, quantified as 8-day LC50 values (5 days on toxic diet, followed by 3 days of untreated feed), were...
