Beaver Impacts On Timber On The Chauga River Drainage In South Carolina, J. Rickie Davis, Judy A. Barnes, George E. Ward, David Van Lear, David C. Guynn Jr., C. Andy Dolloff, Mark Hudy

Wildlife Damage Management Conference

Even though beavers (Castor canadensis carolinensis) occur over most of the southeastern United States, the impacts of increasing beaver populations on riparian forests within the southern Appalachian mountains are not been well documented. Long-term browsing and inundation by beaver may alter the composition and structure of riparian forests. A survey of 62 streams (74 mi) within the Chauga River drainage in the mountains of South Carolina was conducted during 1991- 1992 to determine the level of beaver activity within the drainage and the amount of timber damaged by beaver activities. Thirty-six streams had evidence of significant beaver activity …

Assessment Of Gnawing Behavior Of Three Rodent Species On Automatic Speed Control Mechanism Diaphragms From Gm Automobiles, Glenn R. Dudderar, Ren-Rong Hou, Scott R. Winterstein

Wildlife Damage Management Conference

General Motors and the A C. Rochester Company, a subsidiary of General Motors (GM), has found that the rubber diaphragms on automatic speed control mechanisms (servos) were gnawed by unknown rodents. House mice (Mus musculus), Peromyscus spp., and eastern chipmunks (Tamias striatus) were used to test gnawing behavior on 4 kinds of diaphragms. Diaphragms with or without a rodent proof cure formula, which are used by GM, did not influence the gnawing of all test rodent species. Diaphragms with a lubricant (Paricin) were more attractive to gnawing by house mice than diaphragms without a lubricant. …

Rodent Damage Control In No-Till Corn And Soybean Production, Ron Hines

Wildlife Damage Management Conference

In recent years the primary cause of reduced plant stands in no-till crops planted into heavy residue has been small eared rodents called voles (Microtus spp.). Past research has indicated that severe stand reductions (80 to 100 percent) can occur if vole populations in the field exceed 75 per hectare (30 per acre) at planting time. This vole population should be considered intense. If field scouting about 30 days prior to planting reveals at least 12 active vole colonies per hectare (five per acre) an intense population can develop, and damage control measures should be planned. Of all …

The Effectiveness Of A New Mole Repellent For Preventing Damage To Lawns By Eastern Moles, Glenn R. Dudderar, Stacey Tellman, Dale K. Elshoff

Wildlife Damage Management Conference

A new product containing 65% castor oil with the trade name Mole-Med was evaluated for its effectiveness in repelling eastern moles (Scalopus aquaticus) from lawns. Seven lawns in southern Michigan during September, 1993 were selected as preliminary test sites, and the ridges over mole tunnels in the lawns were flattened each day for 3 days. If some existing and new ridges were raised each day, the site was classified as having mole activity and continuing damage. The repellent was then applied according to label directions, and ridges above mole tunnels were flattened as described previously. If no tunnels …

Bat Exclusion Methods, William H. Kern Jr

Wildlife Damage Management Conference

This publication is intended to serve as a review of currently accepted methods of bat exclusion. Inappropriate house bat control methods are destructive to our decreasing bat populations and often cause additional problems for the building's owner or occupant. These problems include odor from dead bats, infestations of carrion-feeding flies, and increasing human and pet exposure to bats. Appropriate exclusion methods like winter structure modification for cave hibernating bats or one-way excluders using hardware cloth, plastic sheeting, or plastic birdnetting are the best ways to protect these beneficial wildlife species and correct situations where humans and bats come into conflict.

A Comparison Of Deer Hunter And Farmer Attitudes About Crop Damage Abatement In Michigan: Messages For Hunters, Farmers, And Managers, Peter A. Fritzell Jr., Donna L. Minnis, R. Ben Peyton

Wildlife Damage Management Conference

During the last 20 years several states have seen dramatic changes in the size of their white-tailed deer (Odocoileus virginianus) populations and also more frequent debates about how the deer resource should be managed. One central area of conflict between stakeholders involved in deer management is the issue of the lethal control of depredating deer, and how and when programs involving lethal control should be implemented. In the last decade, both Michigan farmers and deer hunters have organized special interest groups to express their dissatisfaction with deer population numbers, deer-caused crop losses, and/or the state's crop depredation control …

Ecosystem Management And Wildlife Management: Compatible Or Conflicting?, David C. Guynn Jr., Greg K. Yarrow

Wildlife Damage Management Conference

Examples of wildlife-human conflicts include deer-automobile collisions, disease transmission concerns, and damage to various commodities (e.g. agricultural crops, timber production). The extent of these problems is increasing at a time when American's attitudes are shifting emphasis from commodity production to concern for the environment. Ecosystem management has been proposed as a strategy to balance concerns for commodity production and the environment. Ecosystem management, unlike traditional natural resource management, will require management over large areas for long periods of time. This new philosophy of land management requires that the natural resource base be viewed in its entirety, and not as separate …

Evaluation Of The Yard Gard Ultrasonic Yard Protector For Repelling White-Tailed Deer, Paul D. Curtis, Christopher Fitzgerald, Milo E. Richmond

Wildlife Damage Management Conference

Ultrasonic devices are marketed for pest control because some manufacturers believe they possess properties aversive to animals. However, there is little evidence that ultrasound is more aversive to animals than is audible sound. In this study, we examined the efficacy of the Yard Gard ultrasonic device for deterring deer (Odocoileus virginianus) from feeding on apples. Four deer feeding stations were established at private residential properties with a history of deer damage to ornamental plants, so that control (A1 and B1) and experimental (A2 and B2) stations existed at each site. Apples were placed at each feeding station and …

Apple Production, Vole Control, And Wild Turkeys: Finding A Balance In Vermont, Richard B. Chipman, Dennis Slate, Abigail J. Duke, Lorraine Berkett, Douglas Blodgett

Seventh Eastern Wildlife Damage Management Conference (1995)

Meadow voles (Crotus pennsylvanicus) and pine voles (Crotus inetorum) cause extensive damage to apple trees by gnawing and girdling trunk and root systems. In 1991, approximately 70% of Vermont's 90 commercial apple producers were using zinc phosphide (ZP) treated cracked corn to manage vole damage. From November 1991 throughout January 1992, 36 confirmed wild turkey deaths were attributed to the broadcast application of ZP treated cracked coin in Vermont orchards. As a result of public concern regarding impacts to nontarget wild turkeys, a working group was formed with representation of various state and federal agencies as …

Pesticide Use By The Federal/Cooperative Animal Damage Control (Adc) Program, 1988-1991, Guy Connolly

Seventh Eastern Wildlife Damage Management Conference (1995)

ADC personnel use many wildlife damage control methods including pesticide products. This paper presents a national overview of the kinds and amounts of chemical pesticides used by ADC in direct control activities during Fiscal Years (FY) 1988-1991. The pesticides used by ADC included aluminum phosphide, 4-aminopyridine, bone tar oil, brodifacoum, carbon, alpha-chloralose, cholecalciferol, DRC-1339, fenthion, glyphosate, immobilizing & euthanizing drugs, mineral oil, PA-14, phosphorus, polybutene, sodium cyanide, sodium fluoroacetate, sodium nitrate, strychnine, sulfur, and zinc phosphide. This summary shows that ADC personnel used remarkably small amounts of chemicals during FY 19881991. Overall amounts of pesticides used by ADC have changed …

A Strategy For Integrating Principles And Concepts Of Wildlife Damage Control Into The School Curriculum, Thomas A. Eddy

Seventh Eastern Wildlife Damage Management Conference (1995)

This paper reports an approach to educating today's youth concerning the importance of regulating numbers of wildlife species that threaten property, products and health. The emphases are on preparing teachers to integrate principles and concepts into the existing curricular materials, justifying control measures with ecological understandings and economic is information and dealing effectively with sensitive animal rights issues. Opportunities for integration of specific wildlife damage control topics are suggested for lessons in the life sciences, social sciences, health, language arts and mathematics. Examples of conflict between groups of different opinions about the seriousness of a pest's activities or appropriateness of …

A Statistical Derivation Of The Significant-Digit Law, Theodore P. Hill

Research Scholars in Residence

The history, empirical evidence and classical explanations of the significant-digit (or Benford's) law are reviewed, followed by a summary of recent invariant-measure characterizations. Then a new statistical derivation of the law in the form of a CLT-like theorem for significant digits is presented. If distributions are selected at random (in any "unbiased" way) and random samples are then taken from each of these distributions, the significant digits of the combines sample will converge to the logarithmic (Benford) distribution. This helps explain and predict the appearance of the significant0digit phenomenon in many different empirical contexts and helps justify its recent application …

Symmetries Of Accola-Maclachlan And Kulkarni Surfaces, Sean A. Broughton, E Bujalance, A F. Costa, J M. Gamboa, G Gromadzki

Mathematical Sciences Technical Reports (MSTR)

For all g greater than or equal to 2, there is a Riemann surface of genus g whose automorphism group has order 8g+8, establishing a lower bound for the possible orders of automorphism groups of Riemann surfaces. Accola and MacLachlan established the existence of such surfaces; we shall call them Accola-MacLachlan surfaces. In this paper we determine the symmetries of surfaces with genus g = 3(mod 4), computing the number of ovals and the separability of the symmetries. The results are then applied to classify the real forms of these complex algebraic curves.

Tailoring Of The Magnetic Properties Of Smco5:Nb0.33Cr0.67 Nanocomposites Using Mechanical Alloying, Richard L. Schalek, Diandra Leslie-Pelecky, John Knight, David J. Sellmyer, Steven C. Axtell

David Sellmyer Publications

Nanocomposite structures composed of ferromagnetic particles dispersed in a matrix are systems in which the magnetic properties can be tailored by varying the size and spacing of the ferromagnetic particles. Nanocomposites of SmCo₅ in a non-magnetic Nb_0.33Cr_0.67 matrix exhibit a wide variety of magnetic properties. SmCo₅ powder is premilled prior to mechanical alloying. The premilliing results in a maximum coercivity of 16 kOe after 2 hours of milling, and an enhanced remanence ratio. Both features may be due to exchange anisotropy and/or exchange coupling between hard and soft ferromagnetic phases. The nanocomposite samples show that, …

Magnetic Switching Volumes Of Cosm Thin Films For High Density Longitudinal Recording, E.W. Singleton, Z.S. Shan, Y.S. Jeong, David J. Sellmyer

David Sellmyer Publications

For a high density recording media, the magnetic switching volume is of great importance when considering media noise and thermal stability. CoSm//Cr films have been prepad and the influence of the Cr underlayer thickness and of the magnetic layer preparation conditions on the magnetic switching volume have been investigated through magnetic viscosity and remnance curve measurements. The measured switching volumes ranged from 3.0 to 15.2x10^-18 cm³, and implications regarding noise and thermal stability are discussed.

A Quasiparticle Trap Assisted Transition Edge Sensor For Phonon Mediated Particle Detection, K. D. Irwin, S. W. Nam, Blas Cabrera, B. Chugg, Betty A. Young

Physics

ABSTRACT We have demonstrated the operation of composite superconducting tungsten and aluminum transition‐edge sensors which take advantage of quasiparticle trapping and electrothermal feedback. We call these devices W/Al QETs (quasiparticle‐trap‐assisted electrothermal feedback transition‐edge sensors). The quasiparticle trapping mechanism makes it possible to instrument large surface areas without increasing sensor heat capacity, thus allowing larger absorbers and reducing phonon collection times. The sensor consists of a 30‐nm‐thick superconducting tungsten thin film with T_c∼80 mK deposited on a high‐purity silicon substrate. The W film is patterned into 200 parallel lines segments, each 2 μm wide and 800 μm long. Eight …

Analysis Of Ladar Range Resolution Enhancement By Sinusoidal Phase Modulation, Leonard T. Masters, Martin B. Mark, Bradley D. Duncan

Electro-Optics and Photonics Faculty Publications

The ability of a ladar system to resolve two or more separate returns from a combined echo is related to the effective correlation bandwidth of the pulse emitted by the ladar system. Phase modulation of an outgoing pulse introduces additional frequency components, which increases the effective correlation bandwidth of the pulse and thus improves the range resolution of the system. In this paper, we discuss the general theoretical basis for achieving improved range resolution using a modulated waveform and a matched filter receiver. We then demonstrate these concepts by considering the particular case of improved range resolution for a sinusoidally …
