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...
Disseminated visceral coccidiosis in whooping cranes
J. W. Carpenter, T.R. Spraker, M.N. Novilla
1980, Journal of the American Veterinary Medical Association (177) 845-848
Three 13- to 18-day-old whooping cranes (Grus americana) and a 9-year-old whooping crane died in outdoor pens at the Patuxent Wildlife Research Center. The deaths were associated with an overwhelming systemic infection by an intracellular protozoan parasite, which resulted in enteritis, granulomatous bronchopneumonia, hepatitis, splenitis, and myocarditis. The clinical, histopathologic,...
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...
The human influence on seabird nesting success: Conservation implications
D. W. Anderson, J.O. Keith
1980, Biological Conservation (18) 65-80
Based on studies of brown pelicans Pelecanus occidentalis californicus and Heermann's gulls Larus heermanni, disturbances by recreationists, educational groups, local fishermen and scientists alike can be seriously disruptive and damaging to breeding seabirds in the Gulf of California and off the west coast of Baja California. Similar instances have been identified throughout the...
Metastatic, papillary cystadenocarcinoma of the mammary gland in a black-footed ferret
J. W. Carpenter, J.P. Davidson, M.N. Novilla, J.C.M. Huang
1980, Journal of Wildlife Diseases (16) 587-592
A simple, papillary cystic adenocarcinoma of the mammary gland with metastases to the internal iliac and mesenteric lymph nodes, liver, and spleen was observed in a 12 to 13 year old female black-footed ferret (Mustela nigripes). Histologically, the tumor was aggressive, and lymphatic invasion was found. Attempts at virus isolation...
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,...
Significance of organochlorine and heavy metal residues in wintering shorebirds at Corpus Christi, Texas, 1976-77
Donald H. White, Kirk A. King, R. M. Prouty
1980, Pesticides Monitoring Journal (14) 58-63
Organochlorine and heavy metal residues were determined in 103 shorebirds of seven species collected at Corpus Christi, Texas, during the winter of 1976-77 to evaluate their potential effects on population survival, DDE and polychlorinated biphenyls (PCBs) were detected in most samples. Chlordane isomers, dieldrin, toxaphene, and heptachlor epoxide also occurred,...
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 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,...
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...
