Role of reef fauna in sediment transport and distribution - Studies from Tektite I and II
H.E. Clifton
1973, Helgoländer Wissenschaftliche Meeresuntersuchungen (24) 91-101
1. Reef organisms may play a major role in the transport and distribution of sediment on the sea floor adjacent to coral reefs. 2. Some fish such as Malacanthus plumieri (Bloch) selectively transport and collect certain types of sediment (such as larger coral and shell fragments). 3. The random movement...
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...
Sea birds wintering off Maryland shores, 1972-73
R.A. Rowlett
1973, Maryland Birdlife (29) 88-102
During the winter of 1972-73, studies were conducted to determine the status and distribution of pelagic species of birds occurring at sea as far as 38 miles east of Ocean City, Md. The wintering off-shore avifauna was found to be impressively rich in variety of species and numbers of...

Organochlorine residues in woodcock wings, 11 states--1970-71
M. Anne Ross McLane, L.F. Stickel, E.R. Clark, D.L. Hughes
1973, Pesticides Monitoring Journal (7) 100-103
A survey of organochlorine residues in woodcock wings was undertaken to determine whether these wings are suitable for showing regional differences in residues and to obtain a baseline in 1970-71 for later comparisons. Woodcock wings were obtained from the annual hunter's wing survey. Samples came from eight States (Louisiana, Maine,...
Molt patterns and weight changes of the American woodcock
Ray B. Owen, W.B. Krohn
1973, The Wilson Bulletin (85) 31-41
A study of molt and changes in body weight of American Woodcock was conducted to better understand the summer and fall behavior of these birds and to indicate periods of physiological stress. The postnuptial molt of adults was a complete molt beginning in late June and ending by the middle...
Distribution of two western clapper rail races as determined by responses to taped calls
R. E. Tomlinson, R.L. Todd
1973, Condor (75) 177-183
During 1969 and 1970, surveys of the endangered Yuma Clapper Rail were conducted using taped calls to elicit responses from the birds. During the two summers, more than 158 Yuma clappers were located in cattailtule marshes along the Colorado River south of Needles, California, to the International Boundary, a distance...

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...
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...
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,...

Two-garnet rodingite from Amador County, California
W. A. Duffield, M.H. Beeson
1973, Journal of Research of the U.S. Geological Survey (1) 665-672
Two distinct phases of garnet have been discovered in rodingite from Amador County, Calif. The two garnets are hydrogrossular and (hydro?) grossular-andradite. Only one, generally hydrogrossular, has been reported in rodingitcs studied by other workers. The rodingite of this study formed from a mafic dike with abundant euhedral plagioclase laths....

1973, Book chapter, Environmental Pollution by Pesticides
SUMMARY: Residues of organochlorine pesticides and their breakdown products are present in the tissues of essentially all wild birds throughout the world. These chemicals accumulate in fat from a relatively small environmental exposure. DDE and dieldrin are most prevalent. Others, such as heptachlor epoxide, chlordane, endrin, and benzene hexachloride...
