Variation Of White-Tailed Deer Home Ranges In Fragmented Urban Habitats Around Chicago, Illinois, Brian P. Piccolo, Karmen M. Hollis, Richard E. Warner, Timothy R. Van Deelen, Dwayne R. Etter, Chris Anchor

Wildlife Damage Management Conference Proceedings

Behavior of white-tailed deer (Odocoileus virginianus) has been studied extensively in refuges and agricultural regions, although little research has focused on deer in urban environments. Dramatic urbanization and development fragments habitat available for wildlife species and deer densities often exceed ecosystem carrying capacity in remnant natural areas. This may impact deer social behavior and spatial home range patterns. We radio-marked 21 female white-tailed deer in the Des Plaines and Palos Forest Preserves near Chicago, Illinois to study spatial use of deer relative to conditions in urban forest preserves. Telemetry locations were collected once per week and included both day and …

Investigations Of Methods To Reduce Damage By Voles, Gary W. Witmer, A. A. Hakim, Brian W. Moser

Wildlife Damage Management Conference Proceedings

Voles (Microtus spp.), small burrowing rodents, range over much of North America. Populations cycle and achieve peak densities every 3-5 years. This can result in severe damage to various resources: orchards, forest plantings, alfalfa and other crops, ornamentals, lawns, and gardens. A variety of methods are used to reduce vole damage, but there is still a need for new, cost-effective, and environmentally benign approaches. We investigated numerous candidate repellents and barriers with indoor vole colonies in soil-filled tanks. Several compounds (blood meal, capsaicin, castor oil, coyote urine, quebracho, and thiram) showed promise as repellents, but only at high concentrations. Many …

Overabundant Deer: Better Management Through Research, Dwayne R. Etter, Timothy R. Van Deelen, Daniel R. Ludwig, Karmen M. Hollis, James E. Chelsvig, Richard E. Warner

Wildlife Damage Management Conference Proceedings

Overabundance of white-tailed deer (Odocoileus virginianus) continues to challenge wildlife professionals nationwide, especially in urban settings. Moreover, wildlife managers often lack general site-specific information on deer movements, survival, and reproduction that are critical for management planning. We conducted radio-telemetry research concurrent with deer culling in forest preserves in northeastern Illinois and used empirical data to construct predictive population models. We culled 2,826 deer from 16 forest preserves in DuPage County (1992-1999) including 1,736 from the 10 km2 Waterfall Glen Forest Preserve. We also radio-marked 129 deer from 8 preserves in DuPage and adjacent Cook County (1994-1998). Recruitment was inversely associated …

Double-Crested Cormorant Satellite Telemetry: Preliminary Insight, Scott J. Werner, D. Tommy King, David E. Wooten

Wildlife Damage Management Conference Proceedings

Migratory paths of North American waterbirds have traditionally been evaluated by relocating birds banded as nestlings. Although over 8,000 banded Double-crested Cormorants (Phalacrocorax auritus) have been recovered in North America since 1923, the movements of wintering and breeding cormorants remain poorly understood. We initiated a satellite telemetry study to determine the annual and regional distributions of 25 cormorants (in each of two study years) captured near primary aquaculture areas in Alabama, Arkansas, Louisiana, and Mississippi. Preliminary data suggest that cormorants generally remained near aquaculture facilities where they were captured, marked, and released. Two cormorants, however, emigrated from primary aquaculture areas …

Conditioning And Habituation Of White-Tailed Deer To Two Common Deterrents, George R. Gallagher, Jennifer L. Peacock, Elizabeth P. Garner, Robert H. Prince

Wildlife Damage Management Conference Proceedings

It was hypothesized white-tailed deer {Odocoileus virginianus) could be readily conditioned to 2 commonly used deterrents, Deer-Away® Big Game Repellent (BGR) and blood meal (BM). Plots were randomly assigned BGR, BM and control. Free-ranging deer were initially conditioned to forage for corn at each 49m2 bare earth plots delivered at 0500 hr and 1600 hr by programmable sling-type feeders. Hoof prints were counted within a 3.7m2 sample area of each plot to quantify activity. Following preconditioning, data were collected during 5, 5-day periods. Application of BGR and BM to their respective bare earth plots occurred during periods 2,4 and 5. …

Effectiveness Of Anise As A Coyote Lure, Coren P. Jagnow, Russ Mason

Wildlife Damage Management Conference Proceedings

Odors are frequently used to attract coyotes (Canis latrans) to control devices. Coyote olfactory perception is vital to effectively manage depredation of livestock by coyotes because of the importance of volatile cues to this species. Lures are usually chosen to reflect the biological needs of coyotes as well as relying on food-seeking behaviors to elicit attraction. Anise (Illicum verum) was chosen as the stimulus because of its attractiveness to dogs and its common use as an ingredient in animal foods. Plants comprise a large part of coyotes' diets during warm weather; therefore, a plant odor was chosen to find an …

Field Evaluation Of A Visual Barrier To Discourage Gull Nesting, Patricia A. Pochop, John L. Cummings, Richard M. Engeman

Wildlife Damage Management Conference Proceedings

Expanding gull populations along the Columbia River have been implicated in depredations to threatened and endangered migrating salmon smolt, depredations to agriculture crops, bird-aircraft strike hazards, nuisance problems, and potential threats to public health. In an effort to develop management methods for controlling gull populations, we tested a visual barrier to discourage gulls from nesting on an island in the Columbia River. The barrier material is a woven black polypropylene fabric that we utilized to take advantage of the gulls' innate predator avoidance mechanisms, by removing their line of sight to approaching terrestrial predators while providing no protection from aerial …

Nonsteroidal Anti-Inflammatory Drugs, Acetaminophen, Cyclooxygenase 2, And Fever, Daniel L. Simmons, David Wagner, Kenneth Westover

Faculty Publications

Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used antipyretic agents that most probably exert their antifever effect by inhibiting cyclooxygenase (COX)–2. Thus, COX-2–selective drugs or null mutation of the COX-2 gene reduce or prevent fever. Acetaminophen is antipyretic and analgesic, as are NSAIDs, but it lacks the anti-inflammatory and anticoagulatory properties of these drugs. This has led to the speculation that a COX variant exists that is inhibitable by acetaminophen. An acetaminophen-inhibitable enzyme is inducible in the mouse J774.2 monocyte cell line. Induction of acetaminophen-inhibitable prostaglandin E2 synthesis parallels induction of COX-2. Thus, inhibition of pharmacologically distinct COX-2 enzyme activity by …

Nanostructured Fept:B2O3 Thin Films With Perpendicular Magnetic Anisotropy, C.P. Luo, Sy_Hwang Liou, L. Gao, Yi Liu, David J. Sellmyer

Sy-Hwang Liou Publications

FePt/B₂O₃ multilayers were deposited by magnetron sputtering onto 7059 glass substrates. By annealing the as-deposited films at 550 °C, nanostructured FePt:B₂O₃ films consisting of FePt grains with L10 structure, embedded in a glassy B₂O₃ matrix, were obtained. The c axes of the FePt grains can be made to align with the film normal direction, which results in a perpendicular anisotropy constant of 3.5×107 erg/cc. The films remain layered structures after annealing when the B₂O₃ layer thickness exceeds 16 Å. The nanostructure of the films was investigated by …

Use Of Goes Thermal Infrared Imagery For Eruption Scale Measurements, Soufrière Hills, Montserrat, William I. Rose, Gari C. Mayberry

Department of Geological and Mining Engineering and Sciences Publications

GOES two-band IR data are used to estimate the magnitude of small eruption clouds (ash; <∼10⁵ tonnes of fine [1–25 µm in diameter] ash, and 5–15 km asl). The method is demonstrated on clouds from Soufrière Hills Volcano, Montserrat in 1997–99. The clouds in early 1999 were much smaller, were generally emplaced lower in the atmosphere and contained an order of magnitude less fine ash than 1997 clouds generated during the most intense phase of the eruption to date. Although GOES has an excellent capability for large eruption clouds, its use for smaller eruptions like Montserrat highlights several shortcomings, including …

Dealing With A Dry Season, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Farmers' approaches to adverse seasonal conditions whether they be frost, flood or low rainfall should be to acquire as much information as possible on the immediate agronomic and financial situations and make a judgement on the longer term implications for the following seasons. Once the information has been acquired, in consultation with advisers, it is necessary to construct and implement agronomic and business strategies to deal with individual situations.

The agronomic and stocking options for the dry season supplied in this booklet deal with questions and issues arising from the Year 2000 season, which has been characterised by a mid …

Correlations Between Burrowing Owl And Black-Tailed Prairie Dog Declines: A 7-Year Analysis, Martha J. Desmond, Julie A. Savidge, Kent M. Eskridge

School of Natural Resources: Faculty Publications

Concern over the status of species associated with prairie dog colonies has increased with the recent proposed listing of black-tailed prairie dogs (Cynomys ludovicianus). We monitored burrowing owl (Athene cunicularia) populations and prairie dog densities in 17 black-tailed prairie dog colonies in the Nebraska panhandle between 1990 and 1996. All prairie dog colonies were controlled at least once during the study. We observed a 63% decline in nesting pairs of burrowing owls and significant declines in burrow densities. Results indicated a time lag in owl response to changes in active burrow densities. However, in the later …

A Class Of Semiparametric Scale-Change Hazards Regression Models And Its Adequacy For Censored Survival Data, Ying Qing Chen

U.C. Berkeley Division of Biostatistics Working Paper Series

A class of semiparametric hazards regression models called the accelerated hazards models was introduced to identify the covariate effect characterized by the scale-change between hazard functions. In this article, we compare the accelerated hazards models with several other popular classes of regression models in statistical literature for censored survival data. We also propose and study some test statistics to assess the models' adequacy. Simulation studies are conducted to evaluate the performance of the test statistics. Actual clinical trials data are analyzed to demonstrate the proposed models and test statistics.

The Influence Of Wave– And Zonal Mean–Ozone Feedbacks On The Quasi-Biennial Oscillation, Eugene Cordero, Terrence R. Nathan

Faculty Publications, Meteorology and Climate Science

The effects of wave and zonal mean ozone heating on the evolution of the quasi-biennial oscillation (QBO) are examined using a two-dimensional mechanistic model of the equatorial stratosphere. The model atmosphere is governed by coupled equations for the zonal mean and (linear) wave fields of ozone, temperature, and wind, and is driven by specifying the amplitudes of a Kelvin wave and a Rossby–gravity wave at the lower boundary. Wave–mean flow interactions are accounted for in the model, but not wave–wave interactions.

A reference simulation (RS) of the QBO, in which ozone feedbacks are neglected, is carried out and the results …

Time Series Analysis Of V815 Herculis Photometry Between 1984 And 1998, Lauri Jetsu, Thomas Hackman, Douglas S. Hall, Gregory W. Henry, Mariitta Kokko, J. You

Information Systems and Engineering Management Research Publications

As a case study of the solar-stellar connection, we have analysed a prolonged time series of BV photometry of the chromospherically active binary V815 Her . The surface differential rotation in the rapidly rotating G5{v} primary caused changes of 4.6% in the seasonal photometric rotation periods. This would imply a differential rotation coefficient of k = 0.184, if the rotation of the starspots follows the solar law of differential rotation and the activity is confined within the same latitudinal range as in the Sun, having k = 0.189 and the spectral-type of G2{v}. Our analysis of the primary and secondary …

Two K Giants With Supermeteoritic Lithium Abundances: Hde 233517 And Hd 9746, Suchitra C. Balachandran, Francis C. Fekel, Gregory W. Henry, Han Uitenbroek

Information Systems and Engineering Management Research Publications

Two unusual Li-rich K giants, HDE 233517 and HD 9746, have been studied. Optical spectroscopy and photometry have been obtained to determine the fundamental parameters of HDE 233517, a single K2 III with an extremely large infrared excess. The spectra yield Teff=4475 K, logg=2.25, [Fe/H]=-0.37, vsini=17.6 km s-1, and a non-LTE logɛ(7Li)=4.22. Photometric observations reveal low-amplitude light variability with a period of 47.9 days. Combined with other parameters, this results in a minimum radius of 16.7 Rsolar and minimum distance of 617 pc. Comparison of spectra obtained in 1994 and 1996 show profile variations in Hα and the Na D …

The A460 is equipped with a joint position proportional, integral, and derivative (PID) controller. The neural network module supplies …

Management Guidelines For Sage Grouse And Sagebrush Ecosystems In Nevada, Bureau Of Land Management

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

These management guidelines and supportive background information promote the conservation of sage grouse (Centrocercus urophasianus) and their sagebrush (Artemisia spp) habitats on Nevada public lands administered by Bureau of Land Management (BLM). The guidelines are intended to provide interim guidance to field managers, without restricting options currently being explored for regional, state, and local sage grouse/sagebrush conservation planning. The guidelines are a Nevada BLM, habitat-specific, adaptation of the recently updated, and soon to be finalized, Western Association of Wildlife Agencies (WAFWA) Draft Guidelines. The Nevada BLM guidelines apply the most current sage grouse science to BLM activities, within the context …

Investigation Of Optimum Sample Number And Timing For Determining Pollution Loads, T. S. Soerens, Marc A. Nelson

Arkansas Water Resources Center Technical Reports

In order to determine the impacts of non point source (NPS) pollution and to develop Total Maximum Daily Loads (Tr\tfDLs), accurate measurements of pollution loads in streams are critical. The objectives of this study were to accurately detemline pollutant loads at two sites by intensive storm sampling, to develop sub-sampling and other data analysis techniques, to detemline the effect of sample interval on load calculation accuracy, and to find the minimum sample interval required to determine storm loads at a required accuracy. The two stream sites used were a 1st order and a 3rd order stream in the Illinois River …

It is considered that the implementation of this policy will protect the natural environment and native fish species. It will also …

Multiple Spatial Scale Assessment Of Coral Reef And Hard-Bottom Community Structure In The Florida Keys National Marine Sanctuary, Steven Miller, Dione W. Swanson, Mark Chiappone

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The zoning plan for the Florida Keys National Marine Sanctuary (FKNMS) established 23 relatively small no-fishing zones distributed mostly along the offshore reef tract in 1997. In 1999, a two-stage, stratified random sampling design based on the proportion of coral reef and hard-bottom types within the FKNMS was conducted. Our study focused on differences in coverage, density, and condition of benthic organisms with respect to habitat type, regional variations, and differences between no-fishing zones and reference sites at 80 locations spanning 200 km. Most variables exhibited significant spatial differences by habitat type or between individual no-fishing zones and reference sites …

Magnetic Properties Of Disordered Ni3C, Lanping Yue, R. Sabiryanov, E.M. Kirkpatrick, Diandra Leslie-Pelecky

Diandra Leslie-Pelecky Publications

The metastable Ni₃C phase has been produced by mechanically alloying Ni and C. Ni₃C particles of diameter 10 nm are produced after 90 h of mechanical alloying with no evidence of crystalline Ni in x ray or electron diffraction. Linear muffin-tin orbital band-structure calculations show that Ni₃C is not expected to be ferromagnetic due to strong Ni-C hybridization in the ordered alloy; however, the introduction of even small amounts of disorder produces locally Ni-rich regions that can sustain magnetism. Mechanically alloyed Ni₃C is ferromagnetic, with a room-temperature coercivity of 70 Oe and …

In Turkey, desertification has been taking place in areas of low rainfall and minimal vegetative cover. In particular, the central, eastern, and southeastern parts of the country are vulnerable to desertification because of erosion, deforestation, and degradation of vegetative cover. Rivers of those regions are characterized by very high sediment yields. Nearly 60% of the country’s soils are subjected to severe erosion and approximately 450 million tons of sediment are carried to rivers each year. Meanwhile, wind erosion has been a very effective desertification process in central and southeastern parts of the country, where annual rainfall varies around 400–500 mm/year. …
