Histopathologic effects of dietary cadmium on kidneys and testes of mallard ducks
Donald H. White, M. T. Finley, J. F. Ferrell
1978, Journal of Toxicology and Environmental Health (4) 551-558
Mallard ducks fed 2, 20, or 200 ppm cadmium chloride were sacrificed at 30, 60, and 90 d. No mortality occurred during the study and body weights remained unchanged. Kidney weights of the 200-ppm group were significantly greater after 60 and 90 d than those of controls; also, testis weights...
Influence of laying on lead accumulation in bone of mallard ducks
M. T. Finley, M. P. Dieter
1978, Journal of Toxicology and Environmental Health (4) 123-129
Paired mallard ducks (Anas platyrhynchos) were given No. 4 lead shot, and bone lead concentrations were compared in drakes and in laying and nonlaying hens. Lead accumulation was significantly greater in bones with a high medullary content (femur and sternum) compared with bones with a lower medullary content (ulna-radius or...
Rehabilitation of birds oiled on two mid-Atlantic estuaries
Matthew C. Perry, Fred Ferrigno, Fairfax H. Settle
1978, Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies (32) 318-325
An estimated 52,500 birds died as a result of 7 major oil spills on 2 mid-Atlantic estuaries between 1973-78. Ruddy ducks (Oxyura jamaicensis) constituted 98% of 12,500 birds known to have died from 5 spills on the Delaware River. Seventy-six percent of 40,000 dead birds from 2 Chesapeake Bay spills...

The California condor, 1966-1976: A Look at its Past and Future
S.R. Wilbur
1978, North American Fauna No. 72
The California condor (Gymnogyps californianus) was studied on about 900 field days between 1966 and 1976. In addition, some 1,000 items of literature, specimen records from 56 museums, and 3,500 reports of condor sitings by cooperators were analyzed. Distribution does not appear to have changed significantly since the...
Status of the peregrine falcon in the Rocky Mountains and the southwestern United States, Baja California, and Mexico (south of Texas)

Philip P. Schaeffer, Sharyn M. Ehlers, editor(s)
1978, Book chapter, Proceedings of the National Audubon Society Symposium on the Current Status of Peregrine Falcon Populations in North America
About 31 pairs of peregrines still nest north of Mexico, from Idaho and Montana south through West Texas, New Mexico and Arizona. At least thirty-six additional pairs nest in Mexico. Although the nesting sites are occupied, the tissues of the peregrine?s prey species still contain high concentrations of pesticides....
Wildlife and electric power transmission

1978, Book chapter, Effects of Noise on Wildlife
Hundreds of thousands of miles of transmission lines have been introduced into our natural environment. These lines and their corridors can be damaging or beneficial to wildlife communities depending on how they are designed, where they are placed, and when they are constructed and maintained. With the current...

Artificial insemination for breeding non-domestic birds

1978, Book chapter, Artificial Breeding of Non-Domestic Animals.
Captive breeding of non-domestic birds has increased dramatically in this century, and production of young often exceeds that of the same number of birds in their native habitat. However, when infertility is a problem, artificial insemination can be a useful method to improve production. Artificial insemination programs with non-domestic birds...

One commercial and 4 laboratory prepared extruded, water-stable diets were fed 3 times a week in 1-g portions to juvenile male and female White River crawfish, Procambarus acutus acutus (Girard), for 10 weeks. The. binding material in the laboratory preparation was alginate (Kelgin), whereas that in the commercial preparation...
A comparative study on the cryogenic preservation of semen from the sandhill crane and the domestic fowl

1978, Book chapter, Artificial Breeding of Non-Domestic Animals
SYNOPSIS: Recent findings on the cryogenic preservation of semen from the crane, Grus canadensis pratensis and the domestic fowl, Gallus domesticus, are compared. Highest levels of post-thaw motility for crane semen (55%) were obtained when semen was diluted 1:1 with the Beltsville Poultry Semen Extender (BPSE) and held for 30...
Spectrophotometric determination of tungsten in rocks by using zinc-dithiol
Philip Aruscavage, Esma Campbell
1978, Journal of Research of the U.S. Geological Survey (6) 697-699
Tungsten is determined in 11 USGS standard rocks by a spectrophotometric procedure that measures the absorbance of the tungsten-dithiol complex. The results are compared with those obtained by other methods. After the samples are dissolved in HClO4 and HF, the tungsten-dithiol complex is extracted into isoamyl acetate and then back-extracted...
Phosphorus in hydrothermal waters of Yellowstone National Park, Wyoming

1978, Journal of Research of the U.S. Geological Survey (6) 755-763
Ninety-seven hot-spring and geyser samples (field acidified to pH<1.4 with HCl or HNO3) from Yellowstone National Park, Wyo., were analyzed for PO4-P using reduced molybdenum-blue and the selective arsenate reducing agent, metabisulfite-thiosulfate. The PO4-P concentrations ranged from below detection limit (~1-73 micrograms per liter). Twenty-five springs had PO4-P concentrations exceeding 6.8 μg/L;...
Significance of age relations above and below upper jurassic ophiolite in the Geysers-Clear Lake region, California
R. J. McLaughlin, E.A. Pessagno Jr.
1978, Journal of Research of the U.S. Geological Survey (6) 715-726
In The Geysers-Clear Lake area of northern California, a fragmented Upper Jurassic ophiolite overlain depositionally by the Great Valley sequence is juxtaposed over deformed and metomorphosed rocks of the Franciscan assemblage along the Coast Range thrust. The basal strata of the Great Valley sequence consist of thick breccias of mafic...
Upper Devonian radiolarians separated from chert of the Ford Lake Shale, Alaska
Brian K. Holdsworth, D. L. Jones, C. Allison
1978, Journal of Research of the U.S. Geological Survey (6) 775-788
Leaching of black bedded chert from the Ford Lake Shale, Kandik Basin, Alaska, with dilute hydrofluoric acid resulted in the complete separation of moderately well preserved radiolarians. Preliminary study of an assemblage obtained from the lower half of the formation revealed six to eight forms apparently identical to specimens previously...
A reexamination of the Pennsylvanian trace fossil Olivellites
Ellis L. Yochelson, David E. Schindel
1978, Journal of Research of the U.S. Geological Survey (6) 789-796
The original interpretation of Olivellites plummeri Fenton and Fenton as the trace of an infaunal gastropod, is reconsidered and rejected. The original slab bearing several examples of O. plummeri has been reexamined and reillustrated. The slab came from the type-locality of O. plummeri in Eastland County, Tex., and is a shallow...
Reconnaissance for microbial activity in the Magothy aquifer, Bay Park, New York, four years after artificial recharge
E.M. Godsy, G. G. Ehrlich
1978, Journal of Research of the U.S. Geological Survey (6) 829-836
Tertiary-treated sewage effluent was injected into the Magothy aquifer at Bay Park, Long Island, N.Y., between 1968 and 1973. In 1977, the microbial flora in water samples from the injection well and from three nearby wells were surveyed. Differences in the composition of the microbial flora among the four wells...
Application of four input-output models for nutrients in Lake Okeechobee, Florida
Ronald L. Miller
1978, Journal of Research of the U.S. Geological Survey (6) 821-828
R. A. Vollenweider's (1975) nonconservative model described concentrations of nitrogen and phosphorus for 1969-70 in Lake Okeechobee, Fla., better than the models of F. Biffi in 1963, R. H. Rainey in 1967, and R. Piontelli and V. Tonolli in 1964. Vollenweider's model predicted concentrations of 1.4 milligrams per liter of...
