Rejex-It™Ag-36, A Potential Tool To Protect Seeds From Bird Depredation, Peter F. Vogt

Wildlife Damage Management Conference

The ever increasing bird populations (e.g., Black birds, geese etc.) are known to cause considerable losses to agriculture. This problem has reached serious proportions for crops that are farmed on large tracts and are seeded by aerial application such as rice and canola. ReJeX-iT™AG-36, a non-toxic, biodegradable bird aversion formulation, derived from food grade ingredients, has been proven in pen tests and field trials to be effective as a seed treatment to prevent birds from eating the treated seeds. The product does not harm the seeds or the effected birds in any way, even if ingested; it just makes the …

Can We Landscape To Accommodate Deer? The Tracy Estate Research Garden, Helen H. Heinrich, Susan Predl

Wildlife Damage Management Conference

The landscape of New Jersey is remarkably rich in vegetation and open space, despite the state's reputation as the nation's most populous state. This landscape is increasingly the product of intense interaction between the white-tailed deer (Odocoileus virginianus) and both native and cultivated vegetation, particularly in suburban communities, where both the whitetail and the vegetation coexist in abundance. Nearly extirpated at the tum of the century due to over-hunting, the state's white-tailed deer population today exceeds 140,000 because habitat is ideal and hunting seasons are carefully regulated. In many instances, where landowners choose not to use hunting as …

Evaluating The Gas Cartridge For Coyotes In Controlling Badgers, Craig A. Ramey

Wildlife Damage Management Conference

Efficacy investigations were conducted in Pampa, TX to evaluate the use of the "GAS CARTRIDGE FOR COYOTES: (Canis latrans) for controlling problem badgers (Taxidea taxus) in burrows. This coyote cartridge with two active ingredients (sodium nitrate and charcoal), produces high concentrations of carbon monoxide when burned and is effective in controlling coyotes in dens. Badgers were live-trapped, immobilized, and equipped with mortality-indicating radio transmitters prior to their release. Movements were monitored for a minimum of 12 days prior to each initial efficacy test and for at least 3 days in follow up tests for survivors. Only occupied …

Impact Of Clearcut Size On White-Tailed Deer Use And Tree Regeneration, James W. Akins, Edwin D. Michael

Wildlife Damage Management Conference

Northeastern forests have experienced regeneration delays and/or failures due to browsing by whitetailed deer (Odocoileus virginianus). Investigations were made in north-central West Virginia to determine if the size of clearcut is correlated with degree of deer browsing, regeneration of shrubs and trees, and percent ground cover by various herbaceous plants. Tree seedlings, woody shrubs, and herbaceous ground cover were recorded in September 1992 and August 1993 on 16, 1-year old clearcuts, ranging in size from 0.8 to 0.2 ha. Woody regeneration was categorized by species, origin, browsed or not, and vegetative height class on 25 systematically arranged sampling …

Status And Management Of Vole Damage To Horticultural Plantings In North Carolina, Peter T. Bromley, William T. Sullivan Jr.

Wildlife Damage Management Conference

A trapping study in 1979 indicated that voles (Microtus pennsylvanicus and M. pinetorum) were distributed widely in North Carolina. In 1991, Extension Agents with the North Carolina Cooperative Extension Service were surveyed to determine the distribution, nature and severity of vole damage to horticultural plantings, home orchards, and other plantings. Data from the statewide trapping survey and the poll of agents coincided to indicate that voles, particularly pine voles, caused damage from the mountains to the coast. Existing, legal control methods were judged grossly inadequate by agents. Pursuant to the surveys, the North Carolina Pesticide Board and the …

Public Policy Education: An Important Wildlife Management Opportunity, Paul D. Curtis

Wildlife Damage Management Conference

Suburban wildlife management issues are generating heated debate between citizen organizations, elected public officials, and state wildlife management agencies. Decisions are being made by town and county officials which directly impact or supersede state authority for managing resident wildlife. As an example, I will focus this discussion on the white-tailed deer (Odocoileus virginianus) management controversy at Durand Eastman Park, in the greater Rochester metropolitan area, New York.

Deer Damage In Tennessee: Landowner Perceptions And Attitudes, Michael M. King

Wildlife Damage Management Conference

White-tailed deer (Odocoileus virginianus) are an important resource for Tennesseans. They are enjoyed by consumptive and nonconsumptive users alike. Approximately 190,000 hunters pursued deer during the 1992-93 hunting season in Tennessee. They successfully harvested 126,999 deer (Greg Wathen, TWRA Assistant Chief of Wildlife, pers. commun.) and it has been estimated that these hunters would have spent approximately $125 million on goods and services related to deer hunting (Whitehead 1991).

Perceptions And Knowledge Of Alabama Fruit And Vegetable Producers Towards Coyotes, M. Chad Philipp, James B. Armstrong

Wildlife Damage Management Conference

Members of the Alabama Fruit and Vegetable Producers Association (AFVP) were surveyed in 1992-1993 to assess their attitudes and knowledge of coyotes and the amount of perceived damage caused by coyotes. A mail-back questionnaire was developed and pilot tested. The revised questionnaire was sent to all members (N = 84) of the AFVP; individuals whose main income is the production of fruits and vegetables. Seventy-seven percent (n = 61) of those surveyed returned completed questionnaires. Tests for nonresponse bias were conducted and results showed no significant difference. Attitudes were assessed using a Likert scale where 1 = respondents favoring maximum …

Wildlife Damage Management Conference

Data from 548 reported accidents involving white-tailed deer (Odocoileus virginianus) and vehicles in Lynchburg during the years 1987-1991 were summarized. A majority (54.4%) occurred in the months October, November and December with 25.9% occurring in November. While accidents occurred at all hours, most (50%) occurred between 1700 and 0100 hrs.; about 12% occurred between 0600 and 0900 hrs. Accidents occurred on all days of the week (range 12.8% to 17.0%) and were not higher on work days. Adverse weather did not seem to be a factor increasing collisions; 80% of collisions occurred in clear weather. Most (75%) accidents …

Landowners Perceptions Of Crop Damage From White-Tailed Deer In South Carolina, Webb M. Smathers Jr., Gary R. Stratton, Derrell Shipes

Wildlife Damage Management Conference

Survey respondents reported a definite increase in the population of white-tailed deer (Odocoileus virginianus) in South Carolina. Almost 73% of the producers from a random sample indicated that deer populations have increased over the five year period preceding 1991. With a higher deer population, crop damage from deer became more prevalent, and 72% of the producers indicated having some level of damage. The producers in the sample had mixed feelings about the damage their crops received with 70% indicating that the damage was either negligible or was tolerable in exchange for having deer around. In South Carolina the …

Status Of Alpha-Chloralose And Other Immobilizing/Euthanizing Chemicals Within The Animal Damage Control Program, Paul P. Woronecki, William L. Thomas

Wildlife Damage Management Conference

In 1992 the U.S. Department of Agriculture (USDA), Animal and Plant Health Inspection Service, Animal Damage Control (ADC) program was granted approval from the U.S. Food and Drug Administration (FDA), under a continuing Investigational New Animal Drug agreement, to use Alpha-chloralose (A-C) nationwide for capturing nuisance waterfowl, coots, and pigeons. FDA and ADC have imposed several requirements, restrictions and conditions on the operational use of A-C. Training and certification are required to use A-C and other approved immobilizing and euthanizing agents.

Convective Turing Patterns, D. A. Vasquez, J. W. Wilder, Boyd F. Edwards

All Physics Faculty Publications

Turing patterns involve regions of different chemical compositions which lead to density gradients that, in liquids, are potentially unstable hydrodynamically. Nonlinear hydrodynamics coupled with a model of Turing pattern formation show that convection modifies and coexists with some Turing patterns and excludes others, and thereby plays a significant role in pattern selection.

Solar Cycle And Seasonal Variationsin F Region Electrodynamics At Millstone Hill, M. J. Buonsanto, M. E. Hagan, J. E. Salah, Bela G. Fejer

Bela G. Fejer

Incoherent scatter radar observations of ion drifts taken at Millstone Hill (42.6°N, 288.5°E) during 73 experiments in the period February 1984 to February 1992 are used to construct, for the first time at this station, average quiet-time E×B drift patterns for both solar cycle maximum and minimum, for the summer, winter, and equinox seasons. The daily variation of V⊥N shows a reversal from northward to southward drifts near noon, and a return to northward drifts in the premidnight hours. The weaker southward drift in the afternoon in summer noted by Wand and Evans (1981) is shown to occur only at …

New Singularity In Anisotropic, Time-Dependent Solutions To Maximally Gauss-Bonnet Extended Gravity, T. Kitaura, James Thomas Wheeler

All Physics Faculty Publications

Among the solutions for anisotropic, time-dependent, maximally Gauss-Bonnet extended gravity, we find a class of curvature singularities for which the metric components remain finite. These new singularities therefore differ in type from the standard Kasner-like divergences expected for this class of theories. We study perturbative solutions near the singularity and show that there exist solutions with timelike paths that reach the singularity in finite proper time. Solving the equation of geodesic deviation in the same approximation, we show that the comoving coordinate system does not break down at the singularity. A brief classification of the corresponding singularity types in Robertson-Walker …

Symmetries Of The Einstein Equations, Ian M. Anderson, C. Torre

Mathematics and Statistics Faculty Publications

We classify all generalized symmetries of the vacuum Einstein equations in four spacetime dimensions. They consist of constant scalings of the metric, and of the infinitesimal action of generalized spacetime diffeomorphisms. Our results rule out a large class of possible ‘‘observables’’ for the gravitational field, and suggest that the vacuum Einstein equations are not integrable.

National Wetlands Inventory Maps, Logan, (Ogden Nw) Ut, Usfws, United States Department Of The Interior, Fish And Wildlife Service

Water

This document was prepared primarily by stereoscopic analysis of high altitude aerial photographs. Wetlands were identified on the photographs based on vegetation, visible hydrology, and geography in accordance with classification of Wetland and Deepwater Habitats of the United States (FWS/OBS-79/31 December 1979). The aerial photographs typically reflect conditions during the specific year and season when they were taken. In addition there is a margin of error inherent in the use of the aerial photographs.

Proceedings Of The Fourth Western Black Bear Workshop, United States Department Of The Interior, National Park Service

Wildlife Conservation and Management

The status of black bears in North America ranges from pest to threatened. The species appears relatively secure throughout most parts of its range except the southeastern coastal plain; in this region a number of disjunct populations exist on primarily publicly owned lands. Concern over the status of Ursus americanus luteolus led to a petition to list this subspecies under the Endangered Species Act. The Endangered Species Act is arguably the most important wildlife legislation in recent years. However, applying this valuable, but young, untested, and evolving legislation to the black bear subspecies is judged unwarranted and premature because of …

Internal Deformation, Evolution, And Fluid Flow In Basement-Involved Thrust Faults, Northwestern Wyoming, James V. Goddard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An integrated field, microstructure, fracture statistic , geochemistry, and laboratory permeability study of the East Fork and White Rock fault zones, of similar age and tectonic regime but different structural level and hydrogeologic history, provides detailed information about the internal deformation and fluid flow processes in fault zones. The primary conclusions of this research are: 1) Fault zones can be separated into subzones of protolith, damaged zone , and gouge /cataclasite, based on physical morphology and permeability structure. At deep structural levels, gouge/cataclasite zones are more evolved (thicker with increased grain size reduction) due to strain localization, higher pressure and …

Modification Of The Eikonal Relation For Chemical Waves To Include Fluid Flow, J. W. Wilder, D. A. Vasquez, Boyd F. Edwards

All Physics Faculty Publications

Propagating wave fronts resulting from autocatalytic chemical reactions have been the focus of much recent research. For the most part, the hydrodynamics resulting from such reactions has been neglected. In this work, a relation is derived for the normal speed of a propagating wave front as a function of the local curvature when fluid motion is allowed. This ‘‘eikonal’’ equation is a generalization of one which was derived in the absence of fluid flow. It is also shown that small variations in the fluid density due to the chemical reaction do not change the form of the relation.

Properties Of Rigid Foams For Application As Materials For Light Weight Structures In Space, Huichen Chi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mechanical and mesoscopic structural properties of rigid cellular foam made of polystyrene have been investigated. Basic properties (e.g., density, total and available porosity, permeability, surface area, isotropicity, and cell size and cell wall thickness distributions) were measured. In most cases, alternative methods were used to determine which methods were most appropriate for the type of samples we studied. Standard compression and deflection mechanical tests were performed. The stress-strain curves and related mechanical properties were found to agree with standard cellular structural models of open-cell foams.

We investigated the effects of small (~ < 5 atm) hydrostatic stress applied to foam samples for long periods of time (~one day). We observed large changes (up to a factor of three) in the stress-strain diagrams, Young's modulus, elastic collapse stress, ultimate strength, resilience, Poisson's ratio, permeability, penetration depth, and available porosity. Effects were most pronounced above 2 atm applied pressure differential, but were observed even for 1 atm loads. Short-term exposure to loads up to ten times as large did not cause comparable changes. These changes were interpreted as resulting from observed changes in the mesoscopic structure occurring near the surface using standard cellular structural models.

This work was originally motivated by applications …

All U.S. Government Documents (Utah Regional Depository)

The Petrochem/EkoTek site was operated by several owners as a refinery from 1953 until 1978 and as a hazardous waste storage treatment facility and a petroleum recycling facility from 1978 through 1988. Removal of essentially all petroleum products and hazardous wastes in tanks and drums was accomplished from 1988 - 1991. The process that will lead to the complete clean-up of the facility is ongoing. The site was added to the National Priorities List (NPL) in October 1992. Exposure of humans to contaminants in soil and air is thought to have occurred near Petrochem. The source(s) of those contaminants in …

Evidence Of Preferential Directions For Gravity Wave Propagation Due To Wind Filtering In The Middle Atmosphere, Michael J. Taylor, E. H. Ryan, T. F. Tuan, R. Edwards

All Physics Faculty Publications

All-sky TV images of wave structure in the near-infrared hydroxyl (OH) nightglow emission were recorded over a 3-month period during May, June, and July 1988 from a high-altitude site at the Mountain Research Station (40.0° N, 105.6° W, 3050 m), near Nederland, Colorado. Well-defined, coherent wave patterns associated with the passage of short period (<1 hour) gravity waves were observed on a total of 22 occasions. The wave motions exhibited similar spatial and temporal properties during each month but a distinct tendency for northward propagation (68% of the wave azimuths within ± 40.0° N), with some eastward motion in May and June, was observed throughout the campaign. Although it is theoretically well known that upward propagating gravity waves can be blocked at a critical layer produced by the interaction of the waves with the horizontal background wind, observational evidence of this phenomenon is rare. To investigate the possibility that the asymmetry in the wave propagation directions was caused by the critical layer, a model based on mean climatological background winds and numerical tidal wave modes valid for any mid-latitude site and time of the year was constructed to show the regions forbidden to upward gravity wave propagation from critical layer theory. These “blocking diagrams” which vary with height and time were constructed for the OH altitude (∼87 km) for the present paper. Comparison of the predicted (i.e., least restricted) and the observed directions of the wave motion show almost complete agreement. This suggests that middle atmospheric winds can play an important role in determining the flux and the azimuthal distribution of short-period waves reaching the upper atmosphere.

Ta(110) Surface And Subsurface Core-Level Shifts And 4f7/2 Lineshapes, D. Mark Riffe, G. K. Wertheim

All Physics Faculty Publications

High-resolution 4f core-level spectra of the Ta(110) surface region have been obtained at 80 and 300 K with 70- and 100-eV synchrotron radiation. The data show that the subsurface core-level binding-energy shift (compared to deeper-lying atoms) for a close-packed bcc(110) surface can be substantial: 65±15 meV for the first underlayer atoms of Ta(110). The surface core-level shift is 360±12 meV at 80 K and decreases by 13±2 meV at 300 K. Final-state screening in both the bulk and surface layers is well described by a constant singularity index of 0.133±0.012. An enhanced phonon broadening at the surface corresponds to a …

Problem Analysis For The Vegetation Diversity Project, David A. Pyke, Michael M. Borman, U.S. Department Of The Interior, Bureau Of Land Management

All U.S. Government Documents (Utah Regional Depository)

Management of the majority of public rangeland in the Great Basin and Columbia-Snake River Plateau falls under the authority of the Bureau of Land Management. The flora of this land ranges from highly diverse native plant communities to deteriorated lands dominated by exotic annuals. Approximately nine percent of the BLM’s 78 million acres of public land in this region is degraded to such a degree that changes in land management alone will not result in significant improvement. The BLM intends to restore native plant communities on these deteriorated lands, but current revegetation techniques used to establish introduced perennial grasses are …
