Unwanted Guests: Evicting Bats From Human Dwellings, Veda Depaepe, Robert H. Schmidt

Vertebrate Pest Conference Proceedings: 16th (1994)

Bats are the second largest order of mammals in the world. Their 925 species are found on all continents except Antarctica. Bats are in serious decline world-wide from shrinking habitat, persecution and pesticides. Historically, bats were recognized for consuming insect pests, but only recently has the critical additional importance of bats in pollination and seed dispersal of semi-tropical and tropical plants been recognized. Bats use artificial structures in place of lost natural habitat, resulting in their destruction out of fear and ignorance. The health risk to humans from bats in buildings is extremely low, but where bat removal is necessary, …

Do Livestock Guarding Dogs Lose Their Effectiveness Over Time?, Jeffrey S. Green, Roger A. Woodruff, William F. Andelt

Vertebrate Pest Conference Proceedings: 16th (1994)

Information about the effectiveness of livestock guarding dogs for reducing coyote predation on sheep was gathered from livestock producers in the Animal Damage Control Livestock Guarding Dog Program and in Colorado. Eighty-two percent of the producers contacted reported that the performance of their dogs remained the same or improved during 1993 compared with previous years. Eighteen percent of the producers reported a decrease in their dog's effectiveness, but most still felt the dogs were a benefit to their livestock operation. Most producers who noted a decrease in effectiveness attributed it to an apparent increase in the number of coyotes and/or …

Assessment Of Toxic Bait Efficacy In Field Trials By Counts Of Burrow Openings, S. Moran, H. Keidar

Vertebrate Pest Conference Proceedings: 16th (1994)

The Levant vole, Microtus guentheri, is a pest of most of the field crops in Israel. It lives in gallery systems, the openings of which are clearly visible, and is active above ground mainly at night. Its activity was assessed by plugging the burrow openings (holes) and, after three nights, counting the number of reopened holes. The efficacy of control by whole wheat toxic baits was determined by counting the number of reopened holes before and after the treatment in random squares. Three chemicals were tested: sodium fluoroacetate, zinc phosphide and brodifacoum. The bait was applied either by hand, …

Bird Control In New Zealand Using Alpha-Chloralose And Drc1339, Peter C. Nelson

Vertebrate Pest Conference Proceedings: 16th (1994)

Horticulturists and the general public in New Zealand are experiencing increasing problems with a number of introduced bird species. This has meant that many people wish to carry out bird control operations themselves to reduce the problems these birds cause. Most of this control will have to be carried out by the growers themselves as there are very few professional bird control personnel in New Zealand. Alpha-chloralose is the only toxin the general public has access to for controlling birds. It is available in a variety of bait forms with a maximum toxic loading of 2% (weight/weight). Registered personnel can …

Active Ingredients In Aphis's Vertebrate Pesticides - Use And Reregistration Status, Craig A. Ramey, Edward W. Schaffer Jr., Kathleen A. Fagerstone, Steven D. Palmateer

Vertebrate Pest Conference Proceedings: 16th (1994)

The Environmental Protection Agency's (EPA) re-registration process has had an extensive impact on the Animal Damage Control Program administered by the Animal and Plant Health Inspection Service (APHIS) of USDA. Specifically, the 1988 Amendment to the Federal Insecticide, Fungicide, and Rodenticide Act required a comprehensive reevaluation of pesticide safety; nearly 500 data submissions have been requested by EPA from APHIS to maintain its federal (Section 3) and state (Section 24(c)) low volume minor use vertebrate pesticide registrations. These registrations are used to control damage to American agricultural resources, mitigate losses to selected wildlife species, and reduce threats to public health …

Contracts And Registration Studies, Donald J. Elias, Ray T. Sterner, Peter J. Savarbe

Vertebrate Pest Conference Proceedings: 16th (1994)

Public and governmental concerns about the health, safety, and environmental impacts of pesticides have led to increased regulatory requirements to determine the hazards and risks associated with their manufacture, distribution, and use. Vertebrate pesticides are regulated by the U.S. Environmental Protection Agency (EPA) under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended. Much of the data required for registration of these pesticides will be generated by commercial testing laboratories under contract to the product registrants or sponsors. In this paper, we address aspects of the contract research process including: 1) an overview of FIFRA requirements, 2) the nature …

What Do Animal Activists Want? (And How Should Wildlife Managers Respond?), Jon K. Hooper Phd.

Vertebrate Pest Conference Proceedings: 16th (1994)

National animal activist organization leaders were interviewed with the aim of better understanding their ideologies with respect to wildlife issues. Interviewees expressed considerable concern about traditional wildlife management practices and associated consumptive recreation activities. They easily identified a number of needed changes, while had difficulty identifying things they liked about the status quo. The top suggested changes related to using more nonlethal management methods and reducing allegiance with consumptive users. The most common "bottom line" concern expressed by interviewees was the alleviation or elimination of unnecessary pain and suffering in wildlife.

Charting A Future: Process And Promise, Bobby R. Acord, Craig A. Ramey, Robert W. Werge

Vertebrate Pest Conference Proceedings: 16th (1994)

The Animal Damage Control program has been heavily involved in strategic planning since its transfer from USDI to USDA. The first effort was undertaken in 1989 by the program's management team. It was an introspective, critical look at what changes were needed to improve the program's strategic position in the natural resources community. That plan failed to achieve the desired objective due principally to the lack of involvement by ADC employees and others outside the program. In 1991, a more comprehensive effort was begun known as "Futuring." In this process, a representative from each organizational level of the program and …

Stowaway Transport Rates Of House Mice (Mus Domesticus) And Deermice (Peromyscus Maniculatus)*, Ann Eileen Miller Baker

Vertebrate Pest Conference Proceedings: 16th (1994)

Stowaway transport rates were obtained from behavioral observations of 14 house mice (Mus domesticus) and 14 deermice (Peromyscus maniculatus) during commercial transport. One house mouse escaped during unloading and flaking of 2,500 kg 2-year old oat hay. Three house mice and two deermice were hand-caught on trucks during unloading of 51,110 kg transported barley straw and grass hay. One house mouse was hand-caught after being buried alive in grain. Two house mice escaped during unloading of a semitruck holding dog food. House mice (one live, six recently-dead) and deermice (two recently-dead) were taken from a feedmill screen over which had …

Resistance To The First And Second Generation Anticoagulant Rodenticides-A New Perspective, A.P. Buckle, C.V. Prescott, K.J. Ward

Vertebrate Pest Conference Proceedings: 16th (1994)

Warfarin resistance was first discovered among Norway rat (Rattus norvegicus) populations in Scotland in 1958 and further reports of resistance, both in this species and in others, soon followed from other parts of Europe and the United States. Researchers quickly defined the practical impact of these resistance phenomena and developed robust methods by which to monitor their spread. These tasks were relatively simple because of the high degree of immunity to warfarin conferred by the resistance genes. Later, the second generation anticoagulants were introduced to control rodents resistant to the warfarin-like compounds, but resistance to difenacoum, bromadiolone and brodifacoum is …

Impacts Of Projected Climate Change On Urban Water Use, United States Department Of The Interior, Bureau Of Reclamation

Water

Urban water use, particularly outdoor use, responds to changes in temperature, precipitation, and other climatic parameters. This study significantly improved the capacity of an existing regional water demand model to estimate the response of both residential and commercial-industrial water demand to changes in climatic parameters. The resulting functional relationships derived from historic time-series climatic and water use data were applied to global climate scenarios for the four Wasatch Front counties of Utah.

Bio-Oxidation Of A Model Voc In Air, Jeong Seop Shim

Theses

This study was performed to find a satisfactory regime of operation for the vapor phase bio-oxidation of ethyl alcohol, a model volatile organic compound (VOC), in a specially designed bioreactor. Ethanol was selected as a model compound representing bakery oven gas pollution. A spirally wound bioreactor module was used within which was immobilized a mixed bacterial culture from aerobic sludge. The activated sludge from municipal wastewater treatment plants readily attached with no pretreatment on the surface of the spiral biosupport which is a polymeric sheet.

The parameters studied were air flow rate and inlet concentrations of ethanol. Ethanol was injected, …

Study On The Remediation Of Organic Soil Contaminated With Polychlorinated Biphenyls Using A Variable Frequency Microwave Furnace, Lili Zou

Theses

The development of new and innovative remediation technologies for soil contaminated with Polychlorinated Biphenyl (PCB) is necessary to fulfill the need of cleanup of contaminated sites. In the past eight years the Laboratory for Microwave treatment as Hazardous Substance Management Research Center has investigated the use of Microwave energy to remediate contaminated soils. A major drawback of using single frequencies of the microwave range is the non-uniformity of the electromagnetic field. In this thesis a Variable Frequency Microwave Furnace (operating between 2.40 and 7.50 GHz) is used to improve the uniformity of the field. A new method is used to …

Variation Of Clonal, Mesquite-Associated Rhizobial And Bradyrhizobial Populations From Surface And Deep Soils By Symbiotic Gene Region Restriction Fragment Length Polymorphism And Plasmid Profile Analysis, P. M. Thomas, K.F. Golly, J. W. Zyskind, R. A. Virginia

Dartmouth Scholarship

Genetic characteristics of 14 Rhizobium and 9 Bradyrhizobium mesquite (Prosopis glandulosa)-nodulating strains isolated from surface (0- to 0.5-rn) and deep (4- to 6-m) rooting zones were determined in order to examine the hypothesis that surface- and deep-soil symbiont populations were related but had become genetically distinct during adaptation to contrasting soil conditions. To examine genetic diversity, Southern blots of PstI-digested genomic DNA were sequentially hybridized with the nodDABC region of Rhizobium meliloti, the Klebsiella pneumoniae nifHDK region encoding nitrogenase structural genes, and the chromosome- localized ndvB region ofR. meliloti. Plasmid profile and host plant nodulation assays were also made. Isolates …

Sulfate And Msa In The Air And Snow On The Greenland Ice Sheet, J L. Jaffrezo, C Davidson, M Legrand, Jack E. Dibb

Earth Sciences

Sulfate and methanesulfonic acid (MSA) concentrations in aerosol, surface snow, and snowpit samples have been measured at two sites on the Greenland Ice Sheet. Seasonal variations of the concentrations observed for these chemical species in the atmosphere are reproduced in the surface snow and preserved in the snowpit sequence. The amplitude of the variations over a year are smaller in the snow than in the air, but the ratios of the concentrations are comparable. The seasonal variations for sulfate are different at the altitude of the Ice Sheet compared to those observed at sea level, with low concentrations in winter …

Field Test Of "Farm For Profit®" Burley Tobacco Production Program, Kenneth L. Wells, Mark Reese

Soil Science News and Views

Considerable interest exists among local farmers in Scott County, Kentucky, about a "Farm For Profit^®" tobacco production program being advocated by the representative of a product supplier as a means of improving burley tobacco production. Because of this interest, we conducted a field test of this program in 1993. The objective was to compare yield results from this "program" with those from two, more conventional practices.

Use Of Pyocin To Select A Haemophilus Ducreyi Variant Defective In Lipooligosaccharide Biosynthesis, A A. Campagnari, R Karalus, M A. Apicella, William Melaugh, A J. Lesse, B W. Gibson

Chemistry Faculty Publications

Haemophilus ducreyi, a cause of genital ulcer disease in developing countries, appears to facilitate the heterosexual transmission of the human immunodeficiency virus in Africa. Despite an increase in studies of this gram-negative human pathogen, little is known about the pathogenesis of chancroid. Our studies have shown that the lipooligosaccharides (LOS) of H. ducreyi may play an important role in ulcer formation. Monoclonal antibody and mass spectrometric analyses identified a terminal trisaccharide present on H. ducreyi LOS that is immunochemically similar to human paragloboside. This epitope is present on the LOS of Neisseria gonorrhoeae, and it may be the site of …

Dose, Robert Katz

Robert Katz Publications

The universal use of dose as a normalizing parameter in radiobiology is based entirely on the availability of measuring instruments. It is a poor basis for predicting or understanding the relationship between an irradiation and the resulting end point. Energy deposited is not the cause of an interaction. It is a secondary effect. The interaction is best described by fluence and cross section. Energy deposited depends principally upon inelastic collision cross sections for the interaction of electrons with molecules. Especially for heavy-ion bombardments, for high-LET radiations, inelastic electron collision cross sections relate only remotely to the observed end points of …

Radiosensitivity Parameters For Lethal Mutagenesis In Caenorhabditis Elegans, F. A. Cucinotta, J. W. Wilson, Robert Katz

Robert Katz Publications

For the first time track structure theory has been applied to radiobiological effects in a living organism. Data for lethal mutagenesis in Caenorhabditis elegans, obtained after irradiation with nine different types of ions of atomic number 1-57 and gamma rays have yielded radiosensitivity parameters (E₀, σ₀, K, m = 68 Gy, 2.5 x 10^-9 cm², 750, 2) comparable with those found for the transformation of C3HT10 1/2 cells (180 Gy, 1.15 x 10^-10 cm², 750, 2) but remote from those (E₀ and σ₀ = ≈2 Gy, ≈5 …

A River Ran Through It... : The Cultural Ecology Of The Santa Clara Valley Riparian Zone, Erin M. Reilly

Research Manuscript Series

This study addresses the nature of human interaction with the riparian environment in the Santa Clara Valley over time. This is not a new anthropological theme. Literature dates to 1863 The Earth as Modified by Human Action, by George P. Marsh); cultural ecologist Betty J Meggars stated: "The relationship- of culture to environment is one of the oldest problems in the science of anthropology ... "(Meggars, 1968:19); and, anthropologist Alfred Kroeber said: "no culture is wholly intelligible without reference to the nonculture, or so-called environmental factors with which it is in relation and which condition it "(Kroeber 1906:297).

The Binational English & Spanish Telecommunications Network, Armando A. Arias Jr.

SSGS Faculty Publications and Presentations

BESTNET was established in the early 1980's, as an effort to link universities on both sides of the U.S.- Mexico border through microwave, satellite and cable television technologies. In the late 1980's BESTNET focused primarily on the development of asynchronous computer mediated learning and teaching in an internationally networked virtual environment. For the past six years (1990's) BESTNET has strengthened its binational ties and continued its "high tech" focus through the development of active or vibrant model technology which is assisting in the creation of an on-line binational university setting that is "borderless" (albeit, seamless to the user). Today, this …

Resonance Raman Investigation Of The Radical Cation Of 1,3,5-Hexatriene, Tamas Keszthelyi, Robert Wilbrandt, Robert J. Cave, Jenifer L. Johnson

All HMC Faculty Publications and Research

The resonance Raman spectrum of the 1,3,5-hexatriene radical cation generated by v-irradiation in a Freon glass is reported. The spectrum is excited at 395 nm in resonance with the second absorption band. Identical spectra are obtained from ionized (E)- and (Z)-1,3,5-hexatriene. The presence of more than one rotamer has to be assumed to account for all the observed resonance Raman bands. The bands are assigned to a mixture of the two rotamers, calculated at lowest energy, the ttt an tct rotamers, on the basis of ab initio ROHF/6-31G calculated harmonic frequencies. The spectrum indicates that …
