Sterilants For Managing The Populations Of Red-Winged Blackbirds (Agelaius Phoeniceus), Andrew Cyr, Diane Lacombe
Sterilants For Managing The Populations Of Red-Winged Blackbirds (Agelaius Phoeniceus), Andrew Cyr, Diane Lacombe
Vertebrate Pest Conference Proceedings: 15th (1992)
Male Red-winged blackbirds (Agelaius phoeniceus) being gregarious, and causing heavy damage to corn crops in the northeast, including southern Québec and Ontario, sterilization has been studied as a mean's to manage their populations. With chemosterilants (thiotepa and Omitrol®) tested, year to year variations in reproductive success occurs. The spermatogenesis is disrupted, but the overall effect is not specific. Biosterilisation with 10.0 μg doses of GnRH-analogue hormones is more specific, and the spermatogenesis is disrupted for at least a month, but several spaced injections were required. No field trials have been done yet.
Unmasking Mascall's Mouse Traps, David C. Drummond
Unmasking Mascall's Mouse Traps, David C. Drummond
Vertebrate Pest Conference Proceedings: 15th (1992)
Twelve mouse traps described and figured by Leonard Mascall in 16th Century England are illustrated and interpreted afresh. Special attention is given to one that is also depicted on the Merode altarpiece, an important 15th Century Dutch painting. Since Mascall's era many of his mouse traps have virtually disappeared. Others have been made more effective by various design changes, including the incorporation of small powerful helical springs and improved release mechanisms, and by the greater use of wire mesh and sheet metal.
An Integrated Approach To The Management Of Urban Canada Goose Depredations, Steven D. Fairaizl
An Integrated Approach To The Management Of Urban Canada Goose Depredations, Steven D. Fairaizl
Vertebrate Pest Conference Proceedings: 15th (1992)
Canada geese (Branta canadensis) in the Reno-Sparks, Nevada urban area have become a problem of increasing significance. Nuisance complaints from city parks, golf courses, and housing developments augment the bird hazard to aircraft operations at the local airport. Eleven goose collisions with commercial aircraft, between January 1986 and April 1989, caused $250,000 in structural damages but no injuries or loss of human life. The Federal Aviation Administration required action be taken to reduce the hazard if airport certification was to continue. A multi-agency task force was formed to develop and implement an integrated pest management plan. Population surveys …

Electronic Frightening Devices For Reducing Coyote Predation On Domestic Sheep: Efficacy Under Range Conditions And Operational Use, Samuel B. Linhart, Gary J. Dasch, Richard B. Johnson, Jerry D. Roberts, C. Joe Packham
Vertebrate Pest Conference Proceedings: 15th (1992)
A portable 12-v battery-operated coyote frightening device was developed for reducing coyote predation on sheep and evaluated on fenced pasture farm flock operations (1979-1982). In 1986, the final experimental model consisted of a PVC case, a timer, a blinking strobe light, and a warbling type siren that was activated for 7-10 seconds at about 6-7 minute intervals throughout the night. The devices were generally suspended about 2 m above the ground and were activated at dusk by a photocell and turned off about 2 hours after dawn by a timer. Here we report tests on high mountain summer sheep ranges …
Reflections On Current (1992) Pocket Gopher Control In California, Rex E. Marsh
Reflections On Current (1992) Pocket Gopher Control In California, Rex E. Marsh
Vertebrate Pest Conference Proceedings: 15th (1992)
Rodenticide options for pocket gopher control are more limited now than anytime in the last 40 years. Strychnine remains the most economical and efficacious of the rodenticides available for use in production agriculture and forestry. The anticoagulant rodenticides, diphacinone and chlorophacinone, provide the best alternative to strychnine where the latter is thought inappropriate (e.g., school grounds, parks, etc.). The development of a behavioral type resistance to strychnine baits is currently jeopardizing control on certain ranches. Perishable baits (e.g., cubed raw carrots) are no longer an option because technical or concentrated strychnine is no longer registered for such uses. The development …
How Glp Provisions Influence Costs Of Rodenticide Field Evaluations, Richard M. Poche
How Glp Provisions Influence Costs Of Rodenticide Field Evaluations, Richard M. Poche
Vertebrate Pest Conference Proceedings: 15th (1992)
Good Laboratory Practice (GLP) guidelines were implemented by the U.S. Environmental Protection Agency in August 1989. The purpose of the standards are to ensure the integrity of laboratory and field studies which are conducted in support of FIFRA permits and pesticide registrations. Since the advent of GLP requirements, the cost of conducting field trials has increased 40 to 200%, depending upon the type of study. The increased expenses associated with laboratory and field testing, coupled with reregistration expenses, and annual EPA and state registration maintenance fees, have placed a tremendous burden on smaller companies in the U.S.
Why Bad Things Happen To Good Animals, Robert H. Schmidt
Why Bad Things Happen To Good Animals, Robert H. Schmidt
Vertebrate Pest Conference Proceedings: 15th (1992)
The terms "good" and "bad" are completely subjective, yet the public has expectations that wildlife damage management professionals "do bad things to good animals." It is argued that wildlife damage management decisions are made in a value-laden context, with science in a supportive role. The principle of collective human values is the driving force of society's concerns, and collective values are currently highlighting animal welfare and other environmental concerns. Wildlife damage management professionals could modify their operational paradigm from a focus on populations of animals to a focus on aggregations of individual animals in order to respond proactively to both …

Development Of A System For Survey Of Radon Concentration Of The Dayton Area Using A Liquid Scintillation Counter And Analysis Of The Data, Taewon Kim
Theses and Dissertations
A system to do a large scale survey was developed. The data obtained from the survey was analyzed using a database. The database incorporated an equation for converting cpm into radon concentration pCi/ℓ). The equation of conversion, protocol for measuring radon concentration, survey form, and a database program were modified (from previous theses) or developed for this thesis. The elution time constant, adsorption time constant, and calibration factor were calculated for equation of conversion. Two surveys were during the course of the thesis. On the first survey, the arithmetic average radon concentration with standard error of the mean was 2.9 …

The compositing technique used to derive global vegetation index (NDVI) from the NOAA-AVHRR radiances, reduces the residual effect of water vapor and aerosol on the NDVI. The reduction in the atmospheric effect is shown using a comprehensive measured data set for desert conditions, and a simulation for grass with continental aerosol. A statistical analysis of the probability of occurrence of aerosol optical thickness and precipitable water vapor measured in different climatic regimes is used for this simulation. It is concluded that for a long compositing period (e.g. 27 day), the residual aerosol optical thickness and precipitable water vapor is usually …
Ectoparasitism As A Cause Of Natal Dispersal In Cliff Swallows, Charles R. Brown, Mary Bomberger Brown
Ectoparasitism As A Cause Of Natal Dispersal In Cliff Swallows, Charles R. Brown, Mary Bomberger Brown
School of Natural Resources: Faculty Publications
Nestling Cliff Swallows (Hirundo pyrrhonota) in southwestern Nebraska that were relatively heavily parasitized by hematophagous fleas (Ceratophyllus celsus) and swallow bugs (Oeciacus vicarius) dispersed to nonnatal colonies to breed the subsequent year, whereas nestlings that were relatively lightly parasitized returned to their natal colony to breed. There were no significant differences between dispersers and nondispersers in natal clutch size, natal brood size, relative hatching date, natal body mass, natal nest's distance from the colony's center, and natal nest's age. There were no sex differences in dispersal tendencies. Dispersing birds tended to move to smaller colonies …

John Muir Newsletter winter, 1992 university of the pacific volume 2, number 1 "ON JOHN MUIR: LETTERS FROM ALASKA" by Robert Engberg Bruce Merrell and I have reviewed the articles which John Muir wrote for the San Francisco Daily Evening Bulletin during the years 1879 and 1880. They suggest that it was during his visits to still-wild Alaska that Muir first learned that he could shape public opinion. Only three years before his Alaska travels he had attempted to influence the California legislature to stop clear-cut logging in the higher Sierra Nevada ranges. The politicians ignored him, and Muir's political …

Netc Tank Farm Five Hazardous Waste Cleanup: An Investigation And Evaluation Of Cleanup Practices For Waste Oil Tanks At Netc, Newport, Ri, David J. Sisson
Marine Affairs Theses and Major Papers
My intention in this paper is to focus on the "chronic" hazardous waste problem stemming from past disposal/storage practices. More specifically, to focus on two underground storage tanks at NETC which were used for the storage of hazardous waste (waste oil tanks). It is now common knowledge that old underground storage tanks throughout the country present a potential ground water contamination hazard which must be dealt with. Over the past decade naval installations have heightened their awareness of environmental responsibilities and implemented recycling programs for the disposal of paper, glass, etc. and have even established programs for fuel collection and …

Marine Spill Response Corporation (Msrc): How It Hopes To Fill The Oil Recovery Requirements Of The Oil Pollution Act Of 1990, Gerald P. O'Reilly
Marine Affairs Theses and Major Papers
The establishment of Marine Spill Response Corporation (MSRC) is a direct outcome of OPA-90 which will have a substantial effect on domestic shipment, storage and traffic of oil. The ramifications of the law will be felt internationally and it has set a precedent for prevention of oil spills from tankers throughout the world. It will have a positive impact on the environment of the world. But it will be costly and the public will ultimately bear the burden of the environment impact.
