The Livestock Protection Collar For Removing Depredating Coyotes: A Search For Perfect Justice?, Dale Rollins Mar 1995

The Livestock Protection Collar For Removing Depredating Coyotes: A Search For Perfect Justice?, Dale Rollins

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Lethal control techniques for controlling coyotes (Canis latrans) are often maligned as a means for resolving coyote depredations on domestic livestock. With the exception of the Livestock Protection Collar (LPC), lethal control methods (e.g., foot-hold traps and neck snares) lack the ability to specifically remove those coyotes actually preying upon livestock. The LPC capitalizes on attack behavior of coyotes to remove offending individuals. Although currently registered for use in 5 states, LPCs have been used routinely only in Texas. Success with LPCS involves an understanding of coyote behavior and proper targeting of collared livestock. LPCs have been used …


Historical Perspective On Coyote Control Methods In Texas, Robert L. Phillips, Gary L. Nunley Mar 1995

Historical Perspective On Coyote Control Methods In Texas, Robert L. Phillips, Gary L. Nunley

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

A variety of control methods used over an 80-year period (1915-1995) contributed to the effective and successful coyote (Canis latrans) damage management program that exists in Texas today. Traps, toxicants, shooting, denning, and dogs were important during the early years of the Texas Animal Damage Control Service (TADCS) program. Aerial hunting and snares evolved as important control tools following the ban on strychnine and Compound 1080 in 1972. The livestock protection collar (LPC) has received increased use in recent years and has been useful in resolving difficult depredation problems. ADC policy along with changing state and federal regulations …


Public Attitudes Toward Predators In Texas, Douglas Reiter, Mark W. Brunson, Robert H. Schmidt Mar 1995

Public Attitudes Toward Predators In Texas, Douglas Reiter, Mark W. Brunson, Robert H. Schmidt

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

A national survey of public attitudes to ward wildlife damage management provided the opportunity to extract a data set from Texas respondents on predator management Texas respondents were generally more supportive of predator control for livestock protection than the rest of the U S., although the overall trends were similar. Lethal technologies scored low on a humaneness scale.


The Re-Establishment Of The Coyote In The Edwards Plateau Of Texas, Gary Lee Nunley Mar 1995

The Re-Establishment Of The Coyote In The Edwards Plateau Of Texas, Gary Lee Nunley

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

In the early 1900s organized predator control was initiated to remove coyotes (Canis latrans) and wolves (C. lupus and C. rufus) from the sheep and goat producing areas of Texas. Operations were begun in the Edwards Plateau, the largest area of sheep concentration. By the 1920s, many of the inner Edwards Plateau counties were considered to be almost free of coyotes and wolves In the 1950s coyotes and wolves were extirpated from most of the Edwards Plateau After a coyote population irruption in the early 1960s, coyotes began to re-establish themselves on the periphery of the …


Sheep And Goat Losses In Relation To Coyote Damage Management In Texas, Gary Lee Nunley Mar 1995

Sheep And Goat Losses In Relation To Coyote Damage Management In Texas, Gary Lee Nunley

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The average reported sheep and goat loss to coyotes (Canis latrans) in 1992 on those properties worked by the cooperative animal damage control program were relatively low. Sheep and goat losses were not evenly distributed among the producers. Geographical distribution of the losses reflected a positive relationship between relative coyote density and livestock losses. The sheep and goat industry is adversely affected by the cumulative losses of those producers suffering high levels of predation.


Coyotes In The Rolling Plains Of Texas, Wyman P. Meinzer Mar 1995

Coyotes In The Rolling Plains Of Texas, Wyman P. Meinzer

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Coyotes (Canis latrans) in the Rolling Plains region of Texas have experienced several factors in the last 40 years that may have possibly influenced population dynamics and feeding niche. The 3 most important changes were (a) the demand for coyote pelts during the 1970s, (b) a region-wide growth of the stocker cattle industry and (c) the increasing incidence of sarcoptic mange. The availability of stocker cattle carcasses may be providing a source of dependable food during a previously stressful period, thus inflating coyote survival and abundance superficially relative to traditional cow/calf ranching areas Sarcoptic mange has been present …


Immunocontraception As A Tool For Controlling Reproduction In Coyotes, Lowell A. Miller Mar 1995

Immunocontraception As A Tool For Controlling Reproduction In Coyotes, Lowell A. Miller

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The development of immunocontraception as a tool for population management of coyotes (Canis latrans) and reduction of coyote predation may provide an environmentally safer alternative to pesticides. Because they are proteins, immunocontraceptive vaccines do not persist in the environment or bioaccumulate in the food chain. The National Wildlife Research Center (NWRC) will examine the effects (immunological, hormonal and behavioral) of treating penned coyotes with 2 immunocontraceptive vaccines: porcine zona pellucida (PZP) and gonadotropin releasing hormone (GnRH). Initial studies will be conducted using traditional subcutaneous injections; however, the goal IS to develop an orally-deliverable immunocontraceptive vaccine as an alternative …


Managing For Coyotes To Enhance Waterfowl Production: An Alternative Perspective, Terry A. Messmer Mar 1995

Managing For Coyotes To Enhance Waterfowl Production: An Alternative Perspective, Terry A. Messmer

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The Prairie Pothole Region (PPR) of North America produces about half of the continent's duck population. Predation on hens, young, and eggs severely impacts duck production In the region decreasing fall flights. Recent studies conducted in the region suggest that management efforts to increase duck production need to consider both habitat and predator effects. Research indicates that managing on the landscape level to protect coyotes in sufficient numbers to exclude red foxes should be encouraged in PPR areas suitable for duck production and where the risks of damage to domestic livestock and other wildlife species are minimal.


The Coyote In Southwestern Folklore, Wyman P. Meinzer Mar 1995

The Coyote In Southwestern Folklore, Wyman P. Meinzer

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Perhaps one of the first mentions of the coyote (Canis latrans) by Anglos in early-day journalism was from Mask Twain's notes during his travels through the plains frontier in the early- to mid-19th century. Touring the frontier region before its inevitable subjugation to ranching and farming, Twain wrote of the coyote and its larger more infamous cousin, the wolf(C. lupus), In words which left no doubt to the reader the popular sentiments for such predators of the day Although derogatory in some respects, Twain did concede respect for Canis latrans and made mention of the tricks …


Coyotes In The Southwest: Dedication To Samuel L. Beasom, Dale Rollins Mar 1995

Coyotes In The Southwest: Dedication To Samuel L. Beasom, Dale Rollins

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

This symposium is dedicated to the life, achievements and memory of Samuel L. Beasom. From the first time that I considered trying to assemble this symposium, Sam Beasom was on my list of key people to include. Sam's professional contributions and his dry wit would surely play a pivotal role in a conference on coyotes in the Southwest, especially one to be conducted in Texas. I never dreamed then that his contributions, and subsequent recognition, would be presented posthumously here today.


Photographing Coyotes, Wyman P. Meinzer Mar 1995

Photographing Coyotes, Wyman P. Meinzer

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Wildlife photography has become an increasingly popular hobby over the last 10 years. Coyotes (Canis latrans) are among the more difficult animals to photograph under natural field conditions (i.e., in the "wild"). For studying and photographing coyotes behaving routinely, I recommend the use of a "draw station" (i.e., cow carcass) and a blind that will all low relatively close inspection of coyote interactions.


Disease And Coyotes In Texas, Danny B. Pence Mar 1995

Disease And Coyotes In Texas, Danny B. Pence

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The coyote (Canis latrans) population in southern Texas has a recurring group of 3 common helminthes and several peripheral species of lesser importance. Although recurrent group analyses have not been applied to other macro- or microparasite communities, there are certain infectious agents with high prevalences that could form recurrent groups, and that are potentially important in tams of impacting host population (ie , coyote) abundance. While the current rabies epizootic involving coyotes in southern Texas is of public health concern, it probably will not have a major impact on the coyote population. Most likely, the net effect of …

Wetlands/Groundwater Quality In Agricultural Landscapes, D. H. Rickerl, D. E. Kringen, T. A. Machacek Jan 1995

Wetlands/Groundwater Quality In Agricultural Landscapes, D. H. Rickerl, D. E. Kringen, T. A. Machacek

Journal of the Minnesota Academy of Science

In the Prairie Pothole Region (PPR - SO, NO, MN, IA), wetlands classified as "semi-permanent" or "seasonal" can act as groundwater recharge sites. The nutrient filtering capacity of wetlands has been investigated for both natural and constructed wetlands linked to surface water, but there is little information available on their subsequent impact on groundwater quality. This study investigates four seasonal and two semi-permanent wetlands in the PPR of eastern South Dakota. Transitional no-till (TNT) and organic farm (ORG) management systems border the wetlands. The objective is to determine the effects of farm management system on wetland surface water and groundwater …

Structure Of Woody Riparian Vegetation In Great Basin National Park, S. D. Smith, K. J. Murray, F. H. Landau, A. M. Sala

Life Sciences Faculty Research

The community composition and population structure of the woody riparian vegetation in Great Basin National Park are described. Community analyses were accomplished by sampling 229 plots along an elevational gradient of 8 major stream systems in the Park. TWINSPAN analysis identified 4 primary species groups that were characterized by Populus tremuloides (aspen), Abies concolor (white fir), Rosa woodsii (Woods rose), and Populus angustifolia (narrowleaf cottonwood) as dominants, respectively. Detrended Correspondence Analysis (DECORANA) showed that the most important environmental factors associated with the distribution of species were elevation and slope, with flood-related physiographic factors having a secondary effect. Analysis of size-class …

Lead In Kentucky Soils, T. W. Struttmann, Lyle V. A. Sendlein, Dave Fletcher

KWRRI Research Reports

This study reviewed the literature on the occurrence of lead in soils and its relationship to waste oil tank leaks. Many studies have been conducted on the natural occurrence of lead in rocks, soils and water. Very low levels (0.001 mg/l to 0.01 mg/l) are found in surface and groundwater, variable levels are found in soils (from less that 10 ppm to as high as 700 ppm but more normally a high of 70 ppm), and the lead levels found in rocks range from 7 to 80 mg/kg.

Risk assessment calculations have been made by several individuals, also with variable …

Managine For Effectiveness And Efficiency In Oil Spill Response, Peter A. Tebeau Jan 1995

Managine For Effectiveness And Efficiency In Oil Spill Response, Peter A. Tebeau

Marine Affairs Theses and Major Papers

Responding to oil spills, even spills of moderate proportion, requires the commitment of substantial manpower and equipment on the part of the responsible party or the federal government. Throughout the response operation, successful spill management entails choosing the most effective and efficient countermeasures and cleanup techniques to remove or neutralize oil in the environment, minimize overall environmental damages from the spill, and insure that the objectives and expectations of government agencies, responsible parties, and the public are met. As the response progresses, effective and efficient management requires determining when response operations should be terminated. In making this decision, the On-Scene …


Linking Landscape Ecology And Ecosystem Health: The Case Of Lunigiana, Italy, Susan Anna Pellanda Jan 1995

Linking Landscape Ecology And Ecosystem Health: The Case Of Lunigiana, Italy, Susan Anna Pellanda

Theses and Dissertations (Comprehensive)

As ecosystem-based management is increasingly used to manage the environment, methods of applying these approaches to resolve environmental and natural resource issues must be established. The concept of ecosystem health can be used to assist in ecosystem-based management since it takes into account the environmental, economic, and social aspects of ecosystems. The aim of this thesis is to demonstrate the manner in which landscape ecology can be used to manage for the goal of obtaining a healthy ecosystem. This is achieved by studying the landscape of Lunigiana, Italy, an agricultural region located near Italy's northwestern coast. Particular emphasis is placed …


The Complexities Of Decision-Making Related To Health Risk Assessments, Barbara A. Knuth Jan 1995

The Complexities Of Decision-Making Related To Health Risk Assessments, Barbara A. Knuth

Maine Policy Review

Maine, like the nation, has focused a great deal of recent attention on determining acceptable levels of environmental and human health risk. Barbara discusses the role and uses of scientific information in risk assessment and public policy debate. Similar to Kevin Boyle's previous article (featured in the December 1994 issue of Maine Policy Review), Knuth discusses the 1992 Maine Board of Environmental Protection hearings which focused on the human consumption of fish potentially contaminated with dioxin.


Radon Reduction, Improvement Of Indoor Air Quality, And Energy Savings Through An Original Solar Ventilation System, Heather E. Rhoads Jan 1995

Radon Reduction, Improvement Of Indoor Air Quality, And Energy Savings Through An Original Solar Ventilation System, Heather E. Rhoads

Dissertations and Theses @ UNI

This study evaluated the improvement of indoor air quality and energy savings achieved, by an original solar ventilation system installed at test sites exhibiting elevated radon levels. Conventional residential energy conservation measures that limit air exchange rates between the indoors and outdoors have been shown to increase concentrations of radioactive radon decay products as well as other indoor air contaminants. Growing concern about radon lung cancer risks, carbon monoxide poisoning, and the "sick building syndrome" have increased demand for improved indoor air quality. Due to added heating and cooling loads, ventilation generally incurs substantial installation and operational costs. All commercially …

Determining Recreational Visitor Carrying Capacity: The Case Of Black Canyon At Lake Mead National Recreation Area, Kenneth C. Forman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lake Mead and Lake Mohave, created by Hoover and Davis Dams respectively, were combined, along with much of the surrounding area, into the Lake Mead National Recreation Area in 1964. The enabling legislation is specific about the duty the National Park Service has to the public to create and maintain this, and other, national recreation areas for the benefit of the visitors, the environment, and future generations. By investigating human impacts on the physical environment (water quality, litter, etc.) and by querying park users on their opinions (with respect to crowding, visitor behavior, etc.), insight can be gained about appropriate …


Development Of An Analysis Method To Identify The Root Causes Of Finding From The Air Force Environmental Compliance Assessment And Management Program (Ecamp), Frederick B. Cade Sep 1994

Development Of An Analysis Method To Identify The Root Causes Of Finding From The Air Force Environmental Compliance Assessment And Management Program (Ecamp), Frederick B. Cade

Theses and Dissertations

The Air Force is committed to being a national leader in achieving environmental compliance. This commitment is exemplified by the Air Force Chief of Staffs goal of no 'notices of violation.' This goal, however, has proven to be elusive. In the early 1990s, the number of Air Force notices of violation (NOVs) increased by 73%, from 103 to 178. One of the reasons may be findings from the Environmental Compliance Assessment and Management Program (ECAMP) are not being utilized effectively. This research developed an analysis method to identify root causes of ECAMP findings. The model emphasized the use of performance …
