Direct conversion of terpenylalkanolamines to ethylidyne N-nitroso compounds
S. L. Abidi
1986, Journal of Organic Chemistry (51) 2687-2694
A series of mono- and diterpenylalkanolamines bearing isopropylidene functionality on the terpene group was reacted with sodium nitrite in aqueous acetic acid to yield ethylidyne N-nitroso analogues. The key feature of this direct conversion involved initial N-nitrosation followed by apparent elimination of a "CH4" unit (not necessarily methane) from the...

Dynamics of alewives in Lake Ontario following a mass mortality
Robert O’Gorman, Clifford P. Schneider
1986, Transactions of the American Fisheries Society (115) 1-14
The U.S. Fish and Wildlife Service and the New York Department of Environmental Conservation assessed the population of alewives Alosa pseudoharengus in U.S. waters of Lake Ontario during 1976–1982 with bottom trawls. Alewives were abundant in 1976 but a die-off greatly reduced their numbers during the winter of 1976–1977. The...

A kinematic model of southern California
R. Weldon, E. Humphreys
1986, Tectonics (5) 33-48
We propose a kinematic model for southern California based on late Quaternary slip rates and orientations of major faults in the region. Internally consistent motions are determined assuming that these faults bound rigid blocks. Relative to North America, most of California west of the San Andreas fault is moving parallel...
Mercury, selenium, cadmium and organochlorines in eggs of three Hawaiian seabird species
H. M. Ohlendorf, S. Harrison
1986, Environmental Pollution (Series B) (11) 169-191
Eggs of three representative species of seabirds (wedge-tailed shearwater Puffinus pacificus; red-footed booby Sula sula; and sooty tern Sterna fuscata) were collected in 1980 to determined differences in heavy metal, Se, and organochlorine residues among species nesting in the Hawaiian Archipelago and among the four nesting sites sampled (Oahu, French Frigate Shoals, Laysan,...
The relationship between body mass and survival of wintering canvasbacks
G.M. Haramis, J.D. Nichols, K. H. Pollock, J.E. Hines
1986, The Auk (103) 506-514
Mass and recapture histories of 6,000 Canvasbacks (Aythya valisineria) banded in upper Chesapeake Bay were used to test two hypotheses: (1) early-winter body mass is associated with the probability of surviving the winter, and (2) early-winter body mass is associated with annual survival probability. Data were analyzed by a binary...
Analysis of utilization of desert habitats with dynamic simulation
B. Kenneth Williams
1986, Journal of Environmental Management (23) 1-18
The effects of climate and herbivores on cool desert shrubs in north-western Utah were investigated with a dynamic simulation model. Cool desert shrublands are extensively managed as grazing lands, and are defoliated annually by domestic livestock. A primary production model was used to simulate harvest yields and shrub...
Reproduction and health of mallards fed endrin
J. W. Spann, G. H. Heinz, C.S. Hulse
1986, Environmental Toxicology and Chemistry (5) 755-759
Concentrations of 0, 1 and 3 ppm endrin in dry duck mash were fed to mallards (Anas platyrhynchos) starting in December, and health and reproduction were measured the following spring and summer. One male fed 3 ppm endrin died with 2.0 ppm endrin (wet weight), a diagnostically lethal level, in...
Acute oral toxicity of sodium cyanide in birds
Stanley N. Wiemeyer, E. F. Hill, J. W. Carpenter, A. J. Krynitsky
1986, Journal of Wildlife Diseases (22) 538-546
Sensitivities of six avian species, black vulture (Coragyps atratus), American kestrel (Falco sparverius), Japanese quail (Coturnix japonica), domestic chicken (Gallus domesticus), eastern screech-owl (Otus asio), and European starling (Sturnus vulgaris), to acute poisoning by sodium cyanide (NaCN) were compared by single dose LD50's....
Differences in mortality among bobwhite fed methylmercury chloride dissolved in various carriers
J. W. Spann, G. H. Heinz, M.B. Camardese, E. F. Hill, John F. Moore, H. C. Murray
1986, Environmental Toxicology and Chemistry (5) 721-724
Twelve-day-old bobwhite chicks were fed a diet containing 0, 5.4 or 20 ppm methylmercury chloride. The methylmercury chloride was added to the diet either in a dry, pulverized form or dissolved in acetone, propylene glycol or corn oil. Mortality was measured for 6 weeks, and samples of liver were saved...
Environmental contaminants in surrogates, foods, and feathers of California condors (Gymnogyps californianus)
Stanley N. Wiemeyer, R.M. Jurek, John F. Moore
1986, Environmental Monitoring and Assessment (6) 91-111
California condor (Gymnogyps californianus) foods and feathers, and turkey vultures (Cathartes aura), common ravens (Corvus corax), and their eggs were collected within the condor range to determine exposure of condors to environmental contaminants. Samples were analyzed for organochlorines and trace elements. Food items contained low concentrations of organochlorines and generally...

Frozen gene pools - A future for species otherwise destined for extinction

Conclusion: Semen banks and ova and embryo banks can be practical methods to maintain gene pools. Gene pool preservation is desperately needed today due to the rapid decline in number of species and their habitat, a matter that is of concern to.biologists, economists, and politicians worldwide. Techniques are available for...
Depression of plasma luteinizing hormone concentration in quail by the anticholinesterase insecticide parathion
Barnett A. Rattner, R.N. Clarke, M. A. Ottinger
1986, Comparative Biochemistry and Physiology, Part C: Comparative Pharmacology (83) 451-453
1. To examine the effects of parathion on basal plasma luteinizing hormone (LH) concentration, male Japanese quail (Coturnix japonica) were orally intubated with 0, 5 or 10 mg/kg parathion and sacrificed after 4, 8 and 24 hr.2. At the 5 mg/kg dose, plasma LH levels were reduced at 4 and...
