During my first employment as a junior biologist conducting food habits analyses at the Patuxent Research Refuge (now Patuxent Wildlife Research Center) of the US Fish and Wildlife Service, the first station director, Arnold L. Nelson, gave each staff biologist the opportunity to spend a little time conducting field studies...
Chemical scent constituents in urine of wolf (Canis lupus) and their dependence on reproductive hormones
J. Raymer, D. Wiesler, M. Novotny, C. Asa, U.S. Seal, L.D. Mech
1986, Journal of Chemical Ecology (12) 297-314
The volatile components of castrated male and ovariectomized female wolf urine were investigated and correlated with the administration of testosterone or estradiol and progesterone. The results indicate that testosterone induces in the castrated male the formation of some compounds typically associated with the intact male, while reducing the levels of...

Frozen gene pools - A future for species otherwise destined for extinction
G.F. Gee
1986, American Association of Zoological Parks and Aquariums Regional Conference Proceedings (1986) 80-87
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...

Sources of variation in extinction rates, turnover, and diversity of marine invertebrate families during the Paleozoic
J.D. Nichols, R.W. Morris, C. Brownie, K. H. Pollock
1986, Paleobiology (12) 421-432
We have recently shown how capture-recapture models can be used in conjunction with stratigraphic range data to estimate taxonomic extinction rates and taxonomic diversity. Here we present a new method that can be used to estimate taxonomic turnover (defined here as the proportion of taxa extant at...
An overview of raptor conservation in Latin America
D. H. Ellis, D.G. Smith
1986, Birds of Prey Bulletin (3) 21-25
Prior to the last decade, biological studies of raptorial birds in Latin America were almost nonexistent. For many species little more was known than their general range and habitat type. The last few years have seen the opening of a door to what will surely be a flood of scientific...

Cholinesterase inhibition in meadow voles (Microtus Pennsylvanicus) following field applications of orthene®
David A. Jett
1986, Environmental Toxicology and Chemistry (5) 255-259
Brain acetylcholinesterase activity in field-caught meadow voles (Microtus pennsylvanicus) was depressed after a field-spray of Orthene® (acephate: acetylphosphoramidothioic acid O,S-dimethyl ester) by as much as 32% in 1982 and 38% in 1983. Short-term recovery was demonstrated and occurred in a time-dependent fashion in 1982. Plasma Cholinesterase levels were more variable but...
Dieldrin and endrin residues in fulvous whistling-ducks in Texas in 1983
Edward L. Flickinger, C. A. Mitchell, A. J. Krynitsky
1986, Journal of Field Ornithology (57) 85-90
Fulvous Whistling-Ducks were collected near nesting areas in the rice fields of Texas in 1983 to determine if these birds continue to carry residue levels of organochlorine contaminants, and if the contaminants were acquired in Texas or Mexico. Adults were collected immediately after they arrived from wintering grounds and juveniles...

Estimating nest detection probabilities for white-winged dove nest transects in Tamaulipas, Mexico
J.D. Nichols, R. E. Tomlinson, G. Waggerman
1986, The Auk (103) 825-828
Nest transects in nesting colonies provide one source of information on White-winged Dove (Zenaida asiatica asiatica) population status and reproduction. Nests are counted along transects using standardized field methods each year in Texas and northeastern Mexico by personnel associated with Mexico's Office of Flora and Fauna, the Texas Parks and...
Analysis of cyanide in whole blood of dosed cathartids
A. J. Krynitsky, Stanley N. Wiemeyer, E. F. Hill, J. W. Carpenter
1986, Environmental Toxicology and Chemistry (5) 787-789
A gas-liquid chromatographic method was modified to quantify both unmetabolized (“free”) and metabolized (“bound”, i.e., thiocyanates) cyanides. The methods for both are efficient and sensitive to 0.05 ppm. Repeated freezing and thawing of whole blood from treated cathartids caused an initial increase in free cyanide concentrations, followed by a gradual...
Potential impacts of agricultural chemicals on waterfowl and other wildlife inhabiting prairie wetlands: An evaluation of research needs and approaches
C.E. Grue, L.R. DeWeese, P. Mineau, G.A. Swanson, J.R. Foster, P.M. Arnold, J.N. Huckins, P.J. Sheenan, W.K. Marshall, A.P. Ludden
1986, Transactions of the North American Wildlife and Natural Resources Conference (51) 357-383
The potential for agricultural chemicals to enter prairie-pothole wetlands and impact wildlife dependent on these wetlands for survival and reproduction appears to be great. However, the actual risk to wetland wildlife from the inputs of these chemicals cannot be adequately assessed at this time, because of insufficient data. Available data...
Antibodies against canine parvovirus of wolves of Minnesota: A serologic study from 1975 through 1985
S.M. Goyal, L.D. Mech, R.A. Rademacher, M.A. Khan, U.S. Seal
1986, Journal of the American Veterinary Medical Association (189) 1092-1094
Serum samples (n = 137) from 47 wild wolves (Canis lupus; 21 pups and 26 adults) were evaluated from 1975 to 1985 for antibodies against canine parvovirus, using the hemagglutination inhibition (HI) test. In addition, several blood samples (n = 35) from 14 of these wolves (6 pups and 8...
Bird poisoning from misuse of the carbamate Furadan in a Texas rice field
Edward L. Flickinger, C. A. Mitchell, Donald H. White, E. J. Kolbe
1986, Wildlife Society Bulletin (14) 59-62
More than 100 birds consisting largely of dickcissels and savannah sparrows, as well as 9 other species of songbirds and sandpipers, died from feeding on planted rice seed treated illegally with Furadan 4F. Brain ChE activity was depressed between 32-85% in 44% of the birds. Carbofuran residues in GI tract...
Winter distribution and oiling of common terns in Trinidad: A further look
R.M. Erwin, G. J. Smith, R. B. Clapp
1986, Journal of Field Ornithology (57) 300-308
Common Terns were studied during January and March 1985 in Trinidad as part of wintering terns in Latin America. Eighty-nine birds were captured, 33 in January, 56 in March. Terns averaged 102 .+-. 0.9 g, with March birds weighing more than those caught in January. This weight is similar...
