Utilizing A Computerized Fish And Wildlife Information System To Solve Animal Damage Control Problems, Jefferson L. Waldon, Charles T. Cushwa, Peter T. Bromley
Utilizing A Computerized Fish And Wildlife Information System To Solve Animal Damage Control Problems, Jefferson L. Waldon, Charles T. Cushwa, Peter T. Bromley
Wildlife Damage Management Conference
Animal damage control professionals are faced with the monumental task of absorbing an enormous amount of literature about animal species. For example, one person cannot become an expert on all facets of dozens of species, much less the 1000 or more fish, reptiles, amphibians, mammals, and birds that fall under the wildlifer's jurisdiction. An important new aid to the wildlife damage control specialist is the computerized fish and wildlife information system (CFWIS). A CFWIS is a tool for systematically compiling and managing information about animal species which reside in a state. Cushwa and Kopf (1984) summarized the development of state …

Computer Assisted Extension Program On Ground Squirrel Control, Terrell P. Salmon, Donald L. Lancaster, Leanne Lasarow
Wildlife Damage Management Conference
Computers have become common place in virtually all phases of agriculture. Most individuals have access to micro-computers and the once apparent intimidation about using them is rapidly disappearing. Because of increased availability and public acceptance, it's no surprise that many Extension programs are using computers as an important component of their educational package. Recently, several computer models have been developed to assist Extension personnel and others in demonstrating proper wildlife damage control decision-making. We have developed such a model which is used to: 1) present ground squirrel control information to the grower, 2) take user (grower) input on production, yields, …
Birds In Hangars- A Messy Problem, Albert E. Bivings Iv
Birds In Hangars- A Messy Problem, Albert E. Bivings Iv
Wildlife Damage Management Conference
Pest birds in hangars and similar man-made structures pose specific health hazards as well as nuisance and corrosion problems. While lethal control or a scaring program may be the best technique for some locations, neither address the long-term problem of the basic attractiveness of these structures to birds. The best long-term solution usually is to exclude the birds with permanently installed plastic or nylon netting. Several methods to accomplish this are discussed.

Air Force Problems With Birds In Hangars, Timothy J. Will
Wildlife Damage Management Conference
The Air Force's Bird - Aircraft Strike Hazard (BASH) Team has been dealing with bird hazards to aircraft for over ten years, primarily through awareness programs, direct assistance to military bases, and through R&D aimed at world-wide BASH reduction. As with any problem where a biological system (in this case, birds) is involved, diversification is important in developing solutions. The BASH Team has recommended a variety of methods for working with hazards from birds. One area of particular concern is the nuisance of pest birds in hangars. These structures are extremely alluring to birds, which seek the roof-supporting I-beams and …
Preventive Control Of Pest Rodents, Walter E. Howard
Preventive Control Of Pest Rodents, Walter E. Howard
Wildlife Damage Management Conference
With "preventive control" of pest rodents, by using rodent bait boxes (stations) on a permanent basis, there is no longer any biological, ecological, or economic reason for rodent pests or health problems to occur in villages, cities, and intensively cultivated agricultural areas, but not pastures or forests. Such pest rodents can usually be eliminated without endangering nontarget species, quite inexpensively, simply, and in a more environmentally desirable manner than most current practices, where the pest rodents are not controlled until populations have built up, which requires large amounts of rodenticides. With preventive control, once the pest rodents have been controlled …
Histoplasmosis And Its Impact On Blackbird/Starling Roost Management, A. R. Stickley Jr., R. J. Weeks
Histoplasmosis And Its Impact On Blackbird/Starling Roost Management, A. R. Stickley Jr., R. J. Weeks
Wildlife Damage Management Conference
Histoplasrnosis is a common and sometimes serious fungal disease that primarily affects the lungs, but can also involve other parts of the human body. The disease is characterized by 3 major forms: acute pulmonary, chronic cavitary, and disseminated histoplasmosis.Two fungicides are effective in treatment of the disease, but serious side effects often result. The occurrence of the fungus, Histoplasma capsulatum, is associated with large quantities of bird and bat excreta that have come in contact with soil. Roost sites must generally be occupied by birds for at least 3 years before soil conditions are conducive to its growth. Once established, …
Removal Of Nesting Starlings With Drc-1339, Douglas I. Hall
Removal Of Nesting Starlings With Drc-1339, Douglas I. Hall
Wildlife Damage Management Conference
DRC-1339-treated crickets (Gryllus sp.) were utilized in an attempt to remove starlings (Sturnus vulgaris) nesting and rearing young in the aircraft hangars at the Little Rock Air Center, Little Rock, Pulaski County, Arkansas. Bait ratio of 1 treated to 5 untreated crickets was used. They were placed under airport night lights where foraging birds naturally gathered to feed on insects attracted to these lights. Adult starlings consumed the crickets as well as fed them to their young. Lethal control was achieved on both age classes of bird. Field test results show promise for the development of …

Relationship Between Seasonal Changes In Forage Quality And Feeding Patterns In Meadow Voles (Microtus Pennsylvanicus), Ronald J. Brooks, Stephen A. Struger
Relationship Between Seasonal Changes In Forage Quality And Feeding Patterns In Meadow Voles (Microtus Pennsylvanicus), Ronald J. Brooks, Stephen A. Struger
Eastern Wildlife Damage Control Conference: 2nd (1985)
Forage analyses revealed that mowed orchards provide a relatively high quality forage to meadow voles (Microtus pennsylvanicus), especially in the fall. Mowed forage was characterized by significantly higher protein and moisture content and significantly lower acid and neutral detergent fibre and lignin than forage from an abandoned orchard. Energy and fat were not significantly affected by mowing.. However, vole numbers declined markedly in mowed regions in comparison to undisturbed areas. Voles preferred to inhabit areas with dense cover even though vegetative dieback had occurred. Voles did not exhibit any distinct preference for either cracked corn (rodenticide carrier agent) …
Estimating Cost-Effectiveness Of Controlling Animal Damage To Conifer Seedlings, David S. Decalesta
Estimating Cost-Effectiveness Of Controlling Animal Damage To Conifer Seedlings, David S. Decalesta
Eastern Wildlife Damage Control Conference: 2nd (1985)
A model for determining the benefit-cost ratio of controlling damage by vertebrate pests to conifer seedlings requires knowledge of the amount, distribution, and duration of animal damage, reduction in damage associated with control, costs of control, methodology and value of trees at harvest. Because control costs occurring in the present must be compared with savings recovered decades later in the future, the model incorporates procedures for discounting or adjusting future monetary benefits into present net worth valuations,, The model allows forest managers to evaluate a wide range of damage costs and savings accruing from use of various control techniques. The …
Economic And Environmental Impacts Of Beavers In North Carolina, David K. Woodward, Robert B. Hazel, Brian P. Gaffney
Economic And Environmental Impacts Of Beavers In North Carolina, David K. Woodward, Robert B. Hazel, Brian P. Gaffney
Eastern Wildlife Damage Control Conference: 2nd (1985)
In 1984, a postal survey of landowners and managers was conducted in North Carolina concerning the presence of beavers (Castor canadensis) on their property. Major objectives of the survey were to determine: (1) current distribution and relative abundance of beavers in North Carolina, (2) the economic and environmental impacts from an apparently increasing beaver population, and (3) landowner attitudes toward these increasing populations. Of the 1,069 questionnaires returned, data was compiled from 456 landowners (43 percent) who confirmed the presence of beaver activity on their property during 1983. A significant increase in beaver numbers and distribution has occurred throughout much …
Glycation Of Amino Groups In Protein, Nancy G. Watkins, Suzanne R. Thorpe, John W. Baynes
Glycation Of Amino Groups In Protein, Nancy G. Watkins, Suzanne R. Thorpe, John W. Baynes
Faculty Publications
Ribonuclease A has been used as a model protein for studying the specificity of glycation of amino groups in protein under physiological conditions (phosphate buffer, pH 7.4, 37 “C). Incubation of RNase with glucose led to an enhanced rate of inactivation of the enzyme relative to the rate of modification of lysine residues, suggesting preferential modification of active site lysine residues. Sites of glycation of RNase were identified by amino acid analysis of tryptic peptides isolated by reverse-phase high pressure liquid chromatography and phenylboronate affinity chromatography. Schiff base adducts were trapped with Na- BH&N and the a-amino group of Lys-1 …

The Survival Of Mesophilic And Thermophilic Bacteria Subjected To Uv Irradiation, Sajida A. Shaikh
The Survival Of Mesophilic And Thermophilic Bacteria Subjected To Uv Irradiation, Sajida A. Shaikh
Masters Theses
Survival curves were determined for the mesophile, Bacillus licheniformis and the thermophile, Bacillus stearothermophilus after subjecting the cells to ultraviolet irradiation. Cells were grown at 37°C for the mesophile and at 55°C for the thermophile.
At low UV exposure times, the thermophile was more resistant to UV irradiation (had a better survival rate) than was the case for the mesophile. At higher exposure times, the situation was reversed, the mesophile having a greater survival rate than the thermophile.
The effect of changes in the temperature during irradiation was also determined. Thermophiles were greatly affected by changes in temperature while the …

Investigation Of Pollution In A Karst Aquifer Utilizing Optical Brightener, John Thrailkill, Ralph F. Wiseman, Bridget R. Scanlon
KWRRI Research Reports
Optical brightener is an additive to laundry detergents and is found contaminating groundwater. Its concentration may rapidly and inexpensively be determined by fluorescence techniques, and because its source is human wastewater, its presence in groundwater serves as a direct indication of pollution from septic tanks, sewer leaks, and landfills.
A total of 105 wells and springs in an area within the Inner Bluegrass Karst Region near Lexington, Kentucky, were described and sampled. Analyses were made for optical brightener (430 samples), total coliform (91), fecal coliform (93), and fecal streptococci (90). As many as 20 optical brightener and 4 bacterial samples …

Thindown In Radiobiology, Robert Katz, D. E. Dunn, G. L. Sinclair
Robert Katz Publications
A new expression for the radial dose distribution, tested against available data, and yielding good agreement with enzyme and virus cross sections, is used to calculate cellular inactivation cross sections from track theory models and parameters. We use a cellular model and radiosensitivity parameters, fitted to HILAC data 15 years ago, to represent mammalian cells irradiated at the UNILAC. The observed branching with Z and the decline in cellular action cross sections with an increase in ion LET are attributed to thindown; that is, to the limits imposed by the maximum radial penetration of delta rays. Target size and structure …

Habitat Suitability Index Models: Snowshoe Hare, R.G. Carreker
United States Department of Agriculture Wildlife Services: Staff Publications
This document is part of the Habitat Suitability Index (HSI) Model Series [Biological Report 82(10)] which provides habitat information useful for impact assessment and habitat management. Several types of habitat information are provided. The Habitat Use Information Section is largely constrained to those data that can be used to derive quantitative relationships between key environmental variables and habitat suitability. This information provides the foundation for the HSI model and may be useful in the development of other models more appropriate to specific assessment or evaluation needs. The HSI Model Section documents the habitat model and includes information pertinent to its …

A Water Quality Element For The Extension Of The Salt Ponds Special Area Management Plan To Quonochontaug, Winnapaug (Brightmans) And Maschaug Ponds, Clarkson A. Collins
Marine Affairs Theses and Major Papers
The Salt Ponds Project scientific research and management efforts were designed to address the management issues typical to barrier beach-lagoon systems. It was anticipated that the finds of the project would be applied to the management of similar estuarine systems in Rhode Island and elsewhere. This paper presents findsings and recommendations relating to water quality and land use for the watersheds of Quonochontaug Pond, Winnapaug Pond, and Maschaug Ponds. With the inclusion of these waterbodies into the SAM Plan framework, all of the barrier beach-coastal lagoon ecosystems of the south shore will come under a plan specifically designed to protect …

Identification Of Soil-Water Chemical Parameters For The Prediction And Treatment Of Suspended Solids In Surface Water Reservoirs Of Coal Mine Lands, V. P. Evangelou, J. H. Grove, R. I. Barnhisel
KWRRI Research Reports
High concentrations of suspended solids in coal mine sedimentation ponds are a factor in lowering water quality. Colloidal particle settling simulations were carried out in the laboratory to test the influence pH and dissolved solids have on concentration and settling rates of suspended solids. The results of the study reveal that the pH range of colloidal coflocculation for the samples tested is between 3.5 and 4.5. Furthermore, liming simulation of acidic sediments, as expected increased colloid dispersion. This increase was dependent on the magnitude of the sodium adsorption ratio (SAR). The greater SAR systems maintained a greater concentration of colloidal …
