The Evaluation Of Alternative Toxins To Sodium Monofluoroacetate (1080) For Possum Control, Charles T. Eason

Vertebrate Pest Conference Proceedings: 15th (1992)

Possum control in New Zealand is dependent on the use of sodium monofluroacetate (1080) and cyanide. Although 1080 is highly effective, its use is restricted to government staff. Cyanide is available for a wider group of licensed operators, but cyanide "shyness" reduces its effectiveness. An acute toxicity program has been set up to identify nonanticoagulant toxins that could be used safely by farmers. Dose-ranging studies showed that possums are susceptible to cholecalciferol, calciferol, gliftor, alpha-chloralose, and nicotine, but not to bromethalin. As lethal doses for these toxins have been ascertained, which of them are likely to be cost-effective and safe …

Interactive Computer Kiosks For Vertebrate Ipm—Status Report, Stephen C. Frantz, Robert M. Durlak

Vertebrate Pest Conference Proceedings: 15th (1992)

The recent outbreak of raccoon rabies in New York State during a period of unprecedented fiscal constraints presents an emerging organizational dilemma—how to handle increasing demands for services in an environment of diminishing resources. As one response to this need, the New York State Department of Health (DOH) is developing an interactive computer system for integrating public education, professional training and public/professional communication. The basic objective is to enhance consumer access to information regarding rabies, Lyme disease and other public health issues; thereby, forming the basis for prevention. In essence, this effort can be classified as an “educational intervention,” the …

Forty Five Years Of Anticoagulant Rodenticides — Past, Present And Future Trends, Malcolm R. Hadler, Alan P. Buckle

Vertebrate Pest Conference Proceedings: 15th (1992)

The anticoagulant rodenticides were discovered in the 1940s and their advantages of efficacy and safety quickly resulted in their use dominating the practice of rodent control in temperate countries. However, the development of resistance to the early compounds within a decade stimulated research culminating in the invention of anew class of anticoagulant, the second generation compounds, active against resistant strains but also overall far more potent than those previously available. A novel baiting strategy, pulsed baiting, was developed to make full use of this valuable characteristic. Pulsed baiting has enabled the use of second generation anticoagulants in situations where early …

Impacts Of House Mouse Activity On Five Types Of Insulation, Scott E. Hygnstrom

Vertebrate Pest Conference Proceedings: 15th (1992)

House mice (mus musculus) cause a variety of problems with livestock, feed, and structures. Researchers have yet to discover an insulative material that is not susceptible to house mouse damage. In this study, house mice caused significant (P < 0.01) increases in the thermal conductance of 10.2-cm thick wall panels, insulated with cellotex, fiberglass, rockwool, styrofoam, and vermiculite. Mouse populations increased 3-to 4-fold inside the insulated panels during the 6-month study period.

Progress On Managing Cattail Marshes With Rodeo® Herbicide To Disperse Roosting Blackbirds, George M. Linz, David L. Bergman, William J. Bleier

Vertebrate Pest Conference Proceedings: 15th (1992)

In August and September 1989 and 1990, we aerially sprayed 8 cattail (Typha spp.) marshes with Rodeo® herbicide to begin evaluating its use for fragmenting dense cattail stands used by roosting blackbirds (Icterinae). Treated marshes were effectively eliminated as roost sites for blackbirds. After 2 years, cattail densities in 4 marshes treated with Rodeo® at 5.8 - 7.0 L/ha were 87% lower than pretreatment densities (P = 0.0001). In 1990, we treated 4 marshes with Rodeo® at 4.7 L/ha. One year later, 6% of the cattails survived in the sprayed areas. Of 7 groups of "indicator birds," only marsh …

The Effect On Australian Animals Of 1080-Poisoning Campaigns, John C. Mcilroy

Vertebrate Pest Conference Proceedings: 15th (1992)

Animals in Australia vary greatly in their sensitivity to 1080 poison, with known LD_50’s ranging from 0.11 to over 800 mg kg ^-1. Many native species, particularly in western Australia, have evolved tolerances to 1080 through ingestion of native plants that contain fluoroacetate or prey that consume those plants. Despite this, some native species, particularly a few herbivorous mammals, birds and rodents, could be poisoned during control campaigns against vertebrate pests. Field studies indicate that poisoning campaigns are not significantly affecting populations of common non-target animals, but further impact studies are required on vulnerable, rare, endangered, or uncommon …

Rodent Damage In Hawaiian Macadamia Orchards, Mark E. Tobin

Vertebrate Pest Conference Proceedings: 15th (1992)

Dollars And Sense Of Alfalfa: Marketing Your High Yield, High Quality Alfalfa At High Prices, David C. Petritz

Kentucky Alfalfa and Stored Forage Conference

It seems every farmer wants to be in the commercial hay business--growing hay for the cash market. Have you ever stopped to think about the amount of hay that would be produced if everyone who talked about producing hay actually produced hay?

Alfalfa In Beef Backgrounding Programs, G. D. Cantrill

Kentucky Alfalfa and Stored Forage Conference

Alfalfa can be a very important part of most beef backgrounding operations. Today I want to look at two ideas about alfalfa.

First, why we should consider making alfalfa our most important crop on a farm that's backgrounding. Secondly, what are some of the ways to best utilize the alfalfa we do produce?

We can say a lot of positive things about why alfalfa can be important to a beef backgrounder. In preparing for this presentation, I talked with several producers about why they grow and feed alfalfa. Most often I came away with the thought: Alfalfa improves cash flow.

Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Vaughn M. Bryant Jr.

School of Natural Resources: Faculty Publications

The most remarkable dietary remains recoverable from archaeological contexts are coprolites. Coprolites are desiccated or mineralized feces that are preserved in sheltered and open sites in arid regions, primarily in the New World. These dietary remains are remarkable from several perspectives. They typically contain a variety of macroscopic and microscopic remains that form interrelated data sets for the reconstruction of diets. Because contexts containing coprolites are typified by excellent preservation, the remains coprolites contain tend to be in better states of preservation than dietary remains recovered from nonfecal deposits. Coprolites also contain the well-preserved remains of intestinal parasites and pathogens …

Nitrogen And Carbon Isotope Studies Of A Bat Guano Core From Eagle Creek Cave, Arizona, Usa, Hiroshi Mizutani, Donald A. Mcfarlane, Yuko Kabaya

WM Keck Science Faculty Papers

Nitrogen and carbon isotope ratios were studied in a stratified deposit of guano of Mexican Free-tailed bats in Eagle Creek Cave, Arizona, U.S.A. Little diagenetic change was observed over the 25-year time span of the guano deposit. High aridity and reduced circulation of air in the cave are hypothesized to have slowed the normally rapid decomposition of the excreta and the subsequent escape of resultant ammonia. The results suggest the high dependency of the speed of diagenetic change on specific physical and other conditions of the caves and indicate that great care need be exercised in the interpretation of the …

Reconnaissance Survey Of Nitrate Concentrations In Ground Water In Howard And Pike Counties, Arkansas, Travis Thornton, Kenneth F. Steele

Arkansas Water Resources Center Technical Reports

In recent years, the rapid growth of poultry and hog production in Arkansas has caused concern regarding nitrate contamination of the ground water. In the study area of Pike and Howard Counties, the number of hogs has increased from 3,300 hogs in 1970 to 75,000 hogs in 1990. Poultr¥ production for the area has increased from 38,933,000 per year 1n 1970 to 62,774,000 per year in 1990. As animal production increases, so does the amount of animal waste that must be disposed. Hog production is of particular concern. Typical hog operations store concentrated animal waste in lagoons prior to land …

Carbon And Nitrogen Isotopic Signatures Of Bat Guanos As A Record Of Past Environments, Hiroshi Mizutani, Donald A. Mcfarlane, Yuko Kabaya

WM Keck Science Faculty Papers

Carbon and nitrogen isotope ratios were measured for various ecogeochemical samples relevant to bat guano ecosystems. In particular, ca. 800-year-old subfossil guano from Jackson's Bay Cave Compex, Jamaica, yielded ratios similar to the modern guano from other Jamaican bat caves but quite different from modern guano of the same area. Diagenetic change and differences in bat food habits were unlikely explanations for the observation. Instead, insects that feed on C4 and CAM plants were the main prey for the bats in present Jackson's Bay area, while the ultimate source of organic matter for bats in other Jamaican caves and for …

An Evaluation Of The Remnant Vegetation Protection Scheme 1988-1991 : A Report, Department Of Agriculture And Food, Western Australia, Soil And Land Conservation Council (W.A.)

All other publications

The objective of the Remnant Vegetation Protection Scheme is to encourage land owners to fence and protect areas of remnant vegetation for the purposes of flora and fauna conservation, land conservation and aesthetics. The means by which land owners are encouraged to protect remnant vegetation is the provision of a grant equal to half the cost of labour and materials to erect a stock-proof fence around the vegetation concerned. The RVPS is jointly administered by the Departments of Conservation and Land Management (CALM) and Agriculture (DAWA), with the latter as the lead agency. CALM contributes substantially to the RVPS through …

Real-Tv : Rtp/L3'S Visual Monitor, Richard Czop

Theses

Today many real-world activities are being monitored and controlled by some type of micro-processor based system. Emphasis is placed on manufacturing and controlling through the use of computers. The inherent nature of these real-world applications makes them difficult to control and monitor. They must be built meeting strict timing constraints and must be predictable. We need to develop simplistic, reliable, and cost effective methods for building, evaluating, monitoring and controlling these complex systems. These tools should provide the user with system insight. At the New Jersey Institute of Technology Real-Time Computing Laboratory, we are building a system that will provide …

Recalcitrance Of Polychlorinated Biphenyls To Biodegradation By Phanerochaete Chrysosporium In Soil, Thierry B. Poncet

Theses

The white rot fungus Phanerochaete chrysosporium has been shown in the past to effectively degrade a number of chlorinated aromatic compounds. Previous investigators (Eaton, D. C., "Mineralization of Polychlorinated Biphenyls by Phanerochaete chrysosporium, a Lignolytic Fungus", Enz. Microb. Technol., 7, 194-196 (1985); Bumpus, J. A., Tien, M., Wright, D., and Aust, S. D., "Oxidation of Persistent Environmental Pollutants by White Rot Fungus", Science, 228, 1434-1436 (1985)) have also claimed that this fungus is capable of mineralizing polychlorinated biphenyls (PCBs) in submerged cultures under stationary conditions. Therefore, the objective of this work was to study the biodegradation activity of the fungus …

Partial Characterization Of The Major Lipooligosaccharide From A Strain Of Haemophilus Ducreyi, The Causative Agent Of Chancroid, A Genital Ulcer Disease, William Melaugh, Nancy J. Phillips, A A. Campagnari, R Karalus, B W. Gibson

Chemistry Faculty Publications

The first preliminary structure of a surface lipooligosaccharide from Haemophilus ducreyi has been determined. The major oligosaccharide was released by mild acid hydrolysis and analyzed by liquid secondary ion and tandem mass spectrometry. The mass spectral data combined with composition and methylation analysis yielded the most probable structure; Gal1----4GlcNAc1----3Gal1----4Hep1----6Glc1----( Hep1----2Hep1----)3,4Hep1---- KDO, where the reducing terminal 3-deoxy-D-manno-octulosonic acid (or KDO) exists in an anhydro form. This anhydro species results from the elimination of a phosphate from C-4 of KDO during mild acid hydrolysis. The core heptose trisaccharide consists of L-glycero-D-manno-heptose, but analysis of the peracetylated sugars indicated that the 1,4-linked heptose …

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 …

Stable Isotope Analysis Using Tunable Diode Laser Spectroscopy, Todd B. Sauke, J. F. Becker, M. Loewenstein

Faculty Publications

Measurements of ratios of stable isotopes are used in such diverse fields as petroleum prospecting, medical diagnostics, and planetary exploration. The narrow emission linewidth available from tunable diode lasers permits high-resolution infrared absorption measurements of closely spaced isotopic rovibrational lines. Our dual beam spectrometer uses the sweep integration technique in a spectral region where adjacent spectral lines are of approximately equal absorbance at the expected isotopic abundances. The experimental results reported here indicate that isotopic ratios of carbon in carbon dioxide can be measured to an accuracy of better than 0.4%. This laser spectroscopic spectrometric technique offers an alternative to …
