Responses of the iguanid lizard Anolis carolinensis to four organophosphorus pesticides
R.J. Hall, D. R. Clark Jr.
1982, Environmental Pollution (Series A) (28) 45-52
Dose related mortality and cholinesterase effects of parathion, methyl parathion, azinphos-methyl and malathion on Anolis carolinensis were investigated. The comparative effects of the four compounds on fish, birds and mammals are well known, but the effects of organophosphates on reptiles have not been studied critically. Sensitivity and patterns of mortality from exposure...
Anarbylus switaki Murphy: An addition to the herpetofauna of the United States with comments on relationships with Coleonyx
T. H. Fritts, H.L. Snell, R.L. Martin
1982, Journal of Herpetology (16) 39-52
Anarbys switaki, a species previously known only from Baja California Sur, Mexico, occurs in eastern San Diego and southwestern Imperial Counties in California. In California, specimens tend to have continuous transverse bars on the body, are lighter in color, and more slender in body form than in southern Baja California....
Migratory peregrine falcons, Falco peregrinus, accumulate pesticides in Latin America during winter
Charles J. Henny, F.P. Ward, K.E. Riddle, R. M. Prouty
1982, Canadian Field-Naturalist (96) 333-338
Blood samples from 433 Peregrine Falcons (Falco peregrinus) during fall and spring migrations, 1976-80, indicated that most of their pesticide burden, primarily DDE, was accumulated on wintering grounds in Latin America. DDE in spring migrants returning from Latin America for the first time declined significantly from 1979 to 1980. Only...
Study of aggregative behavior of Rhinophrynus dorsalis tadpoles: design and analysis
M.S. Foster, R.W. McDiarmid
1982, Herpetologica (38) 395-404
We conducted experiments using the apparatus and design followed by Wassersug and Hessler (1971) and Wassersug (1973) to test the aggregative behavior of tadpoles of Rhinophrynus dorsalis in response to visual and olfactory stimuli. Results neither supported nor refuted the hypothesis that either stimulus is used as a mechanism...
Enzyme activities in plasma, liver, and kidney of black ducks and mallards
J. Christian Franson
1982, Journal of Wildlife Diseases (18) 481-485
Activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine phosphokinase (CPK), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) were measured in plasma, liver, and kidney, and gamma-glutamyl transferase (GGT) was measured in liver and kidney of black ducks (Anas rubripes). Activities of ALT, AST, GGT, and ornithine carbamyl transferase (OCT)...
Fall and winter homesite use by wolves in northeastern Minnesota
F.H. Harrington, L.D. Mech
1982, Canadian Field-Naturalist (96) 79-84
Post-abandonment homesite use by wolves (Canis lupus) was studied by radio-tracking and simulated howling in two packs in Superior National Forest, Minnesota. Pups, yearlings, and adults returned intermittently to former homesites up to four months after abandonment, usually after prolonged separation from the pack in early fall. Returns...
Techniques for trapping, aging, and banding wintering canvasbacks
G.M. Haramis, E.L. Derleth, D.G. McAuley
1982, Journal of Field Ornithology (53) 342-351
Techniques used to trap, band, and determine age of Canvasbacks during winter on Chesapeake Bay are presented. Canvasbacks were captured with welded-wire traps baited with corn. Two trap designs were used and traps and trapping techniques are described. Ducks were dipnetted from traps and held in modified poultry crates...
Toxicity of dietary lead in young cockerels
J. Christian Franson, Thomas W. Custer
1982, Veterinary and Human Toxicology (24) 421-423
Day-old cockerels received 1850 ppm dietary lead for 4 wks. Blood delta-aminolevulinic acid dehydratase (ALAD) activity was reduced to 1.6% of control activity by the end of the study. Hemoglobin concentration (Hb) in lead-exposed cockerels was significantly less than that of controls at 7, 14, and 28 days,...
Organochlorine residues in bats after a forest spraying with DDT
Charles J. Henny, Chris Maser, John O. Whitaker Jr., T. Earl Kaiser
1982, Northwest Science (56) 329-337
Background levels of DDT and its metabolites (ZDDT) were extremely low or not detected in five species of forest-dwelling bats in northeastern Oregon, i.e., areas not sprayed with DDT in 1974. Other organochlorine pesticides were rarely found and no polychlotinated biphenyls (PCBs) were detected at any time during the study....
Observer variability in estimating numbers: An experiment
R.M. Erwin
1982, Journal of Field Ornithology (53) 159-167
Census estimates of bird populations provide an essential framework for a host of research and management questions. However, with some exceptions, the reliability of numerical estimates and the factors influencing them have received insufficient attention. Independent of the problems associated with habitat type, weather conditions, cryptic coloration, ete.,...
Further interpretation of the relation of organochlorine residues in brown pelican eggs to reproductive success
L. J. Blus
1982, Environmental Pollution (Series A) (28) 15-33
This study was conducted to provide additional interpretation of the relation of organochlorine pollutants to reproductive success and population stability of brown pelicans Pelecanus occidentalis in the southeastern United States from 1969 to 1977. The sample egg technique was employed in South Carolina; it involved collecting an egg from each of 156...
Inorganic and organic mercury chloride toxicity to Coturnix: Sensitivity related to age and quantal assessment of physiologic responses
E. F. Hill
1982, Dissertation Abstracts International (43) 57B-58B(abs)
The toxicities of mercuric chloride (HgCl(,2)) and methylmercuric chloride (CH(,3)HgCl) were compared for coturnix (Coturnix coturnix japonica) from hatching to adulthood. Comparisons were based on: (1) Median lethal dosages (LD50) derived by administering single peroral and single intramuscular dosages of mercury, (2) median lethal concentrations (LC50) derived by feeding mercury...
Inclusion body hepatitis in kestrels (Falco sparverius)
L. Sileo, J. C. Franson, D.L. Graham, C.H. Domermuth, Barnett A. Rattner, O. H. Pattee
1982, Conference Paper, Wildlife Disease Association Conference Proceedings
Inclusion body disease of suspected adenovirus etiology was the apparent cause of death of 9 captive kestrels (Falco sparverius). Cloacal hemorrhage was the only prominent gross lesion; disseminated hepatocellular necrosis and intranuclear inclusion bodies were evident microscopically. Attempts to reproduce the disease, and to propagate and serologically characterize...
