Pesticide residues in eggs of wild birds: Adjustment for loss of moisture and lipid
L.F. Stickel, Stanley N. Wiemeyer, L. J. Blus
1973, Bulletin of Environmental Contamination and Toxicology (9) 193-196
Eggs of wild birds collected for the purpose of measuring concentrations of pesticides or other pollutants vary from nearly fresh to nearly dry so that objective comparisons cannot be made on the basis of weight of the contents at the time of collection. Residue concentrations in the nearly dry...
Serotypes in Saccharomyces telluris: Their relation to source of isolation
H.F. Hasenclever, R. M. Kocan
1973, Infection and Immunity (7) 610-612
Three serotypes have been characterized with three reference strains of Saccharomyces telluris and designated as A, B, and C. One reference strain of Torpulopsis bovina, the imperfect form of S. telluris, belonged to serotype B.Strains (141) of S. telluris isolated from four columbid species were serotyped. All 98 strains of this yeast isolated from Columba livia (feral...
Bird collections in the United States and Canada
Richard C. Banks, M.H. Clench, J.C. Barlow
1973, The Auk (90) 136-170
This survey was initiated in 1966 as a project of a subcommittee of the A.O.U.'s Committee on Research, at that time chaired by Paul H. Baldwin. The subcommittee consisted of the authors and Ralph J. Raitt. In 1968 the project was separated from the Committee on Research and the temporary...
Elimination pattern of aroclor 1254 components in the bobwhite
George E. Bagley, E. Cromartie
1973, Journal of Chromatography (75) 219-226
The gas-liquid chromatographic profile for Aroclor 1254 did not maintain its integrity in bobwhite quail fed Aroclor 1254 for 14 days and clean food 14 or 42 days thereafter. Absorption of all components occurred at essentially the same rate, as shown by analysis of quail sacrificed within an hour...
Eggshell thinning, chlorinated hydrocarbons, and mercury in inland aquatic bird eggs, 1969 and 1970
R.A. Faber, J.J. Hickey
1973, Pesticides Monitoring Journal (7) 27-36
In the Upper Great Lakes States, 9 out of 13 species of fish-eating birds were found in 1969-70 to have sustained statistically significant decreases in eggshell thickness since 1946. Maximum changes in a thickness index occurred in great blue herons (-25%), red-breasted mergansers (-23%), common mergansers (-15%). and double-crested...
DDE effects on reproduction of ring doves
M. A. Haegele, R. H. Hudson
1973, Environmental Pollution (4) 53-57
Reproductive performance was measured for 126 days in twelve pairs of ring doves (Streptopelia risoria) fed a diet containing 40 ppm of p,p'-DDE and in twelve other pairs given untreated food. The DDE-treated doves took an average of 212">2 1/2 times longer to renest than controls,...
Eggshell breakage by incubating black ducks fed DDE
J. R. Longcore, F. B. Samson
1973, Journal of Wildlife Management (37) 390-394
Black duck (Anas rubripes) hens fed 10 ppm dry weight (approximately 3 ppm wet weight) of p,p'-DDE in the diet laid eggs with shells 22 percent thinner at the equator, 30 percent thinner at the cap, and 33 percent thinner at the apex than those of controls. Natural incubation increased...
Proceedings of the ninetieth stated meeting of the American Ornithologists' Union
Richard C. Banks
1973, The Auk (90) 171-189
The Ninetieth Stated Meeting of the American Ornithologists' Union was held 14-18 August 1972 at Grand Forks, North Dakota, under the sponsorship of the University of North Dakota and the North Dakota Natural Science Society. Business and technical sessions were held on the campus of the University; some social activities...
Propagation of barn owls in captivity
J.R. Maestrelli
1973, The Auk (90) 426-428
Some aspects of the biology and life history of native birds often are more readily obtained in captivity than in the field. This is particularly true in evaluating the effects of pesticides or other pollutants on birds, because establishing cause-and-effect relationships requires experimental studies. Few wild species have been bred...
