Intestinal absorption of 5 chromium compounds in young black ducks (Anas rubripes)
W. C. Eastin Jr., S. D. Haseltine, H. C. Murray
1980, Toxicology Letters (6) 193-197
An in vivo intestinal perfusion technique was used to measure the absorption rates of five Cr compounds in black ducks. Cr was absorbed from saline solutions of KCr(SO4)2 and CrO3 at a rate about 1.5 to 2.0 times greater than from solutions of Cr, Cr(NO3)3, and Cr(C5H7O2)3. These results suggest the ionic...

Toxic effects of endrin and toxaphene on the southern leopard frog Rana sphenocephala
R.J. Hall, D. Swineford
1980, Environmental Pollution (Series A) (23) 53-65
Eggs, larvae and sub-adults of the southern leopard frog Rana sphenocephala were exposed to endrin and toxaphene. Exposure was in water by a continuous-flow technique, following standards that have been used successfully in the study of fish and invertebrates. R. sphenocephala is more sensitive to both pesticides than are higher vertebrates but is slightly...
Lead residues in eastern tent caterpillars (Malacosoma americanum) and their host plant (Prunus serotina) close to a major highway
W. N. Beyer, John Moore
1980, Environmental Entomology (9) 10-12
Eastern tent caterpillars, Malacosoma americanum (F.) (Lepidoptera: Lasiocampidae), and leaves of their host plant, black cherry, Prunus serotina Ehrh., were collected in May, 1978, at various distances from the Baltimore-Washington Parkway, Prince George's Co., MD, and were analyzed for lead by atomic absorption spectrophotometry. Caterpillars collected within 10 m of the parkway contained 7.1–7.4...

On getting involved
Richard C. Banks
1980, The Auk (97) 637-638
The American Ornithologists' Union and its members had an early history of involvement in public affairs and conservation activities. A very active Committee on Bird Protection was among the first of the service committees to be established. In the 1880s it gathered data on the plumage trade and worked...
Waterfowl production estimates on forested wetlands from pair and brood counts
R.E. Kirby
1980, Wildlife Society Bulletin (8) 273-278
Waterfowl pair and brood counts and estimates of total brood utilization were obtained from 10 beaver (Castor canadensis) flowages in north-central Minnesota and compared with rank correlation techniques. Summing the data for each species, correlation between pair and brood censuses was significant ( p = 0.8304, P < 0.025). Similarly,...
Organochlorine pollutants in small cetaceans from the Pacific and south Atlantic Oceans, November 1968-June 1976
T. J. O'Shea, R.L. Brownell Jr., D. R. Clark Jr., W.A. Walker, M. L. Gay, T. G. Lamont
1980, Pesticides Monitoring Journal (14) 35-46
Organochlorine residues were analyzed in blubber, brain, or muscle tissues of 69 individuals representing 10 species of small cetaceans. Collections were made from November 1968 through June 1976 at localities in the Eastern Tropical Pacific and along the coasts of California, Hawaii, Japan, and Uruguay, Relations of residue concentrations between...
Organochlorine residues and shell thickness in eggs of the clapper rail, common gallinule, purple gallinule, and limpkin (Class Aves), eastern and southern United States, 1972-74
Erwin E. Klaas, H. M. Ohlendorf, E. Cromartie
1980, Pesticides Monitoring Journal (14) 90-94
Organochlorine residues and shell thicknesses were surveyed in eggs of the clapper rail (Rallus longirostris), purple gallinule (Porphyrula martinica), common gallinule (Gallinula chloropas), and limpkin (Aramus guarauna) from the eastern and southern United States. Clapper rail eggs were collected during 1972-73 in New Jersey, Virginia, and South Carolina. During 1973-74,...
Influence of a local source of DDT pollution on statewide DDT residues in waterfowl wings, northern Alabama, 1978-79
W. James Fleming, T. J. O'Shea
1980, Pesticides Monitoring Journal (14) 86-89
Heavy DDT contamination resulting from a former DDT manufacturing plant in northern Alabama has influenced statewide averages of DDT, DDE, and TDE residues in duck wings tested in the National Pesticide Monitoring Program. In states where contaminant levels in duck wings are high, residue analyses of wings categorized by finer...
Organochlorine and heavy metal residues in black duck eggs from the Atlantic Flyway, 1978
S. D. Haseltine, B.M. Mulhern, C. Stafford
1980, Pesticides Monitoring Journal (14) 53-57
Black duck (Anas rubripes) eggs were collected during 1978 in the Atlantic Flyway. One egg from each of 49 clutches was analyzed for organochlorine compounds and mercury. DDE was detected in 39 eggs, ranging from 0.09 ppm to 3.4 ppm, wet weight. DDE residues were highest in eggs from Delaware,...

1980, Report
The objective of this survey is to investigate the methods of interpolation and deconvolution for image restoration The methods evaluated are nearest neighbor, bilinear interpolation, cubic convolution, and two-dimensional deconvolution. The effects of these restoration methods are demonstrated using Landsat multispectral scanner (MSS) data and synthetic imagery. The effect of these...

Long-term bird population trends based on accumulated ratios (proportional change) sometimes give a very misleading view of population change. Alternate methods of representing population change, based on the weighted means for the individual years, avoid the dangers of using ratios. Some advantages and disadvantages of various weighting techniques...
