Effects Of Grackle Damage Control Techniques In Citrus On Nesting Success Of Non-Target Species, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores

Great Plains Wildlife Damage Control Workshop Proceedings

Several techniques were tested to reduce the damage caused by great-tailed grackles to citrus in the lower Rio Grande Valley of southern Texas: monofilament line, eyespot balloons, pyrotechnics, and grackle nest removal. Ten species were found nesting in the treated groves, but only the mourning dove, white-winged dove, and great-tailed grackle in significant numbers. Nesting success was not reduced significantly by any treatment but observations indicate that cannon treatments are likely to have a negative impact on overall nesting success for several species.

Controlling Raccoon Damage In Urban Areas, David G. Riley

Great Plains Wildlife Damage Control Workshop Proceedings

Raccoons have become a serious problem in many urban and suburban areas. Damage to homes and buildings as well as the spread of diseases to pets are constant problems when high raccoon populations occur. Various control methods can be implemented with positive results.

Planning For Animal Damage Control Programs Within The Animal And Plant Health Inspection Service, Philip S. Gipson, Gary P. Combs

Great Plains Wildlife Damage Control Workshop Proceedings

The Animal Damage Control Unit (ADC) and the 10 other units of the Animal and Plant Health Inspection Service (APHIS) have undergone major reorganization. Emphasis is placed on planning and risk analysis. Four levels of planning have been identified: (1) strategic planning for the Agency, (2) strategic planning for each of the 11 units, (3) program design and risk analysis, and (4) operational planning.

Seasonal Effects On Control Methods For The Great-Tailed Grackle, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores, John Hobbs, Joe Palacios

Great Plains Wildlife Damage Control Workshop Proceedings

Efficiency of methods used to control damage to citrus fruit by great-tailed grackles was found to vary considerably from season to season. From April - July, the birds congregated in small breeding colonies where they were susceptible to baiting and poisoning. From August - October, the birds could be baited in to and poisoned at watering sites. Intensive shooting and use of pyrotechnics were also used successfully at this time of year to control damage at groves with high grackle concentrations. From late October - March, birds moved over wide areas each day, and were easily frightened from groves by …

An Assessment Of The Urban Wildlife Problem, William D. Fitzwater

Great Plains Wildlife Damage Control Workshop Proceedings

Basic urban wildlife problems include: proper identification of species, shift from agrarian to urban society, different interpretations of humaneness, compassion for individual rather than a population as a whole, and public ignorance of urban pest management. Positive values are esthetics and environmental education opportunities. Negative values are disease transmission, life/injury-threatening situations, damage to buildings/other property, water structures/quality, petty annoyances, and indirect economics.

Urban Nuisance Wildlife Problems In Arizona, Rebecca L. Wright, Leonard L. Ordway

Great Plains Wildlife Damage Control Workshop Proceedings

Arizona has experienced an increase in urbanization of wildlife habitat, which has led to an urban nuisance wildlife problem. The Arizona Game and Fish Department is working to lessen the problem through public education, information packets and use of private pest control companies to remove wildlife for a fee.

Management Problems Encountered With Livestock Guarding Dogs On The University Of California, Hopland Field Station, Robert M. Timm, Robert H. Schmidtz

Great Plains Wildlife Damage Control Workshop Proceedings

Guard dogs are being promoted and utilized as effective predator damage control tools under a variety of livestock management conditions. We report our experience over 1 1/2 years with 5 dogs, primarily Anatolian shepherd and Akbash dog breeds. We discuss a number of behavioral and management problems we have encountered, some of which have not previously been reported in the literature. These include chasing vehicles and wildlife, predation on deer (Odocoileus hemionus columbianus), and incompatibility of dogs with other predator damage control methods.

Seasonal Variation In Habitat Use By Great-Tailed Grackles In The Lower Rio Grande Valley, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Alan R. Tipton, Nancy Koerth

Great Plains Wildlife Damage Control Workshop Proceedings

Habitat use by great-tailed grackles was measured by performing weekly censuses of birds in 6 different habitat types: chaparral, citrus groves, feed lots, pastures, residential areas, and agricultural fields. We found that use of chaparral, citrus, and residential sites was low during the winter months, increased sharply with commencement of the nesting season in April, and declined again by October. Use of agricultural fields and pasture was irregular. Feed lot use was low during the summer, but high from October - April with October and March migration peaks. An overall sex ratio of 1.3 females/male was observed with skews from …

Transactivation Of Human Immunodeficiency Virus Promoter By Human Herpesvirus 6, Rebecca Horvat, Charles Wood, N. Balachandran

Nebraska Center for Virology: Faculty Publications

Patients with acquired immunodeficiency syndrome (AIDS) are often infected with a number of other heterologous viruses in addition to the initial human immunodeficiency virus (HIV) infection, and these agents could act as potential reactivating agents of latent HIV. A new antigenically distinct herpesvirus, designated human herpesvirus 6 (HHV-6), has recently been isolated from patients with AIDS and has been shown to infect a number of different human cells, specifically human T cells, B cells, and glial cells. Since these are some of the same cells that harbor the AIDS virus, it is quite important to determine any interaction between this …

Silica Exposure And Silicosis Among Ontario Hardrock Miners: Ii. Exposure Estimates, D. K. Verma, A. Sebestyen, J. A. Julian, D. C. F. Muir, H. Schmidt, Charles D. Bernholz, H. S. Shannon

University of Nebraska-Lincoln Libraries: Faculty Publications

An epidemiological investigation was carried out to determine the relationship between silicosis in hardrock miners in Ontario and cumulative exposure to silica (free crystalline silica-α quartz) dust. This second report describes a side-by-side air-sampling program used to derive a konimeter/gravimetric silica conversion curve. A total of 2,360 filter samples and 90,000 konimeter samples were taken over 2 years in two mines representing the ore types gold and uranium, both in existing conditions as well as in an experimental stope in which dry drilling was used to simulate the high dust conditions of the past. The method of calculating cumulative respirable …

Biochemical And Morphological Characteristics In Maturing Achenes From Purple-Hulled And Oilseed Sunflower Cultivars, Roger W. Bullard, Paul P. Woronecki, Richard A. Dolbeer, J. Russell Mason

United States Department of Agriculture Wildlife Services: Staff Publications

The blackbird feeding preference for sunflower oilseed variety Jacques Discovery (JD) over purple-hulled Neagra de Cluj (NdC) has been attributed to anthocyanin. To test this hypothesis, we compared biochemical and morphological properties in the achene over the maturation period. Comparisons included total phenols, anthocyanin, tannin, fat/oil, protein, nonstructural sugars, and phytomelanin contents, as well as mass properties and moisture content. Only three differences were observed: (1) Hull mass was significantly higher for NdC than JD. (2) Anthocyanins were synthesized by NdC only. (3) JD was higher in oil content. Each of these factors may play a role in reduced preferences …

The Use Of Banding Recovery Data To Estimate Dispersal Rates And Gene Flow In Avian Species: Case Studies In The Red-Winged Blackbird And Common Grackle , William S. Moore, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Dispersal resulting in gene flow strongly affects the evolution of genetic structure in populations. This report describes statistical estimators of dispersal parameters based on USFWS banding recovery records. Finite-area studies of avian species yield estimates of root-mean-square (RMS) dispersal along a transect of about 1 km per generation. In contrast, estimates of RMS dispersal for the Red-winged Blackbird (Agelaiusp hoeniceus) and Common Grackle (Ouiscalus auiscula), based on USFWS banding recovery records, are 94.6 and 111.4 km per generation, respectively. Distributions for both species are extremely leptokurtic, and confidence intervals based on jackknife statistics are large because the estimators are sensitive …

Shooting Yourself In The Foot With Due Care: Psychotherapists And Crystallized Standards Of Tort Liability, Robert F. Schopp, David B. Wexler

Nebraska College of Law: Faculty Publications

Professional organizations sometimes promulgate guidelines intended to inform their members' practice. These standards may be designed to guide practitioners under ordinary conditions, or they may define an ideal toward which to strive. If courts adopt idealized standards as criteria of responsible practice for the purpose of establishing tort liability, professional organizations might respond by refraining from developing such guidelines or by framing them with an eye toward preventing liability rather than strictly for the purpose of enhancing patient care. In either case, the courts' actions and the organizations' responses might hinder, rather than enhance, the therapeutic project of the mental …

The Comparative Effectiveness Of Systematic Desensitization And An Integrative Approach In Treating Public Speaking Anxiety: A Literature Review And A Preliminary Investigation, Ana M. Rossi, William J. Seiler

Department of Communication Studies: Faculty Publications

An analysis of the literature related to public speaking anxiety (PSA) and various treatments of it are discussed. PSA is a state or situational type of anxiety which can have tremendous effects on those who suffer from it. Two of the major treatments—systematic desensitization (SD) and the integrative approach (IA)—are reviewed and then experimentally tested to determine which is the more effective in treating PSA. The results are somewhat inclusive, but there is strong evidence to suggest that both SD and IA reduce trait and state anxiety. It was found, however, that IA is more effective in decreasing the symptoms …

Nebraskans And Educational Pluralism, Helen A. Moore

Center for Public Affairs Research (UNO): Publications

Equality of educational opportunity continues to be a goal of public education and of the communities served. To meet the diverse needs of racial and ethnic minorities and female students, policy makers must untangle layers of government guidelines, while attending to the goals of local constituents.

The under-representation of minorities among public school graduates, and gender and race inequality in school teaching and administrative staffs, are discussed in this chapter. Community attitudes toward pluralistic goals and integration in education are highlighted, and suggestions are made for coordinating the diverse needs of all students.

A Blocking Elisa For The Detection Of Specific Antibodies To Bovine Respiratory Syncytial Virus, Marvin B. Rhodes, Carol A. Klucas, Merwin L. Frey, Gary A. Anderson

Roman L. Hruska U.S. Meat Animal Research Center: Reports

A blocking enzyme-linked immunosorbent assay (ELISA) has been adapted to detect specific antibodies in bovine sera to respiratory syncytial virus using a horseradish peroxidase-labeled monclonal antibody to the fusion protein of the virus. This assay plus an indirect blocking ELISA and indirect ELISA were used to detect antibodies to the bovine respiratory syncytial virus (BRSV) in 159 field-origin bovine sera. Results of these assays were compared with serum antibody titers measured by the serum neutralization (SN) test. Over a 56-day period, the mean neutralization titers and the mean delta absorbance values for the blocking ELISA, on the same sera, showed …

Defining "Professionals" Within 25-222: An Approach Intended By Nebraska's Legislature?, Janine E. Rempe

Nebraska Law Review

In Nebraska, physicians, lawyers, accountants, architects, engineers, medical technicians, and certain investment advisors render "professional" services, but real estate brokers do not—that is, for purposes of Nebraska's professional negligence statute of limitations, section 25-222 of the Revised Statutes of Nebraska ("25-222"). As evidenced by this summary of Nebraska law, the Nebraska Supreme Court has repeatedly used a definitional, classificatory approach in determining to whom the statute's protection may be extended. That is, the court has focused on who ranks as a "professional" before allowing certain parties to use 25-222 as a defense. To determine which occupations are "professions," the court …

Pig Vocalizations Under Selected Husbandry Practices, H. Xin, J. A. Deshazer, Daniel W. Leger

Department of Psychology: Faculty Publications

Acoustical characteristics of vocalizations of sows, piglets, and nursery pigs under selected husbandry practices were analyzed with a digital signal processing system. The duration (D) and major energy-resonance frequency (P) for each call were determined as follows: a) processing of piglets (D = 0.81 s and f* = 3 700 Hz); b) food anticipation of breeding-gestation sows (2.50 s and 3 000 Hz); c) isolation of piglet (0.34 s and 500, 3 500 Hz); d) startling of nursery pigs (0.29 s and 900 Hz); e) sows in heat (3.07 s and 1 375 Hz); f) farrowing (0.10 s and 3 …

Use Of Trpe/Gag Fusion Proteins To Characterize Immunoreactive Domains On The Human Immunodeficiency Virus Type 1 Core Protein, Michael Windheuser, Gary Tegtmeier, Charles Wood

Nebraska Center for Virology: Faculty Publications

The human immunodeficiency virus (HIV) p24 core protein is one of the most immunogenic of HIV structural proteins. Infected individuals develop high titers of antibodies against p24 early in infection, which makes anti-p24 antibodies important serological markers. However, despite the clinical importance of the anti-p24 response, no systematic study to characterize the antigenic domains on the p24 protein has been reported. We report here on the use of 12 overlapping fragments of the HIV type 1 p24 protein, synthesized in bacteria as TrpE/Gag fusion proteins, to identify at least two and possibly three antigenic domains on the p24 protein. In …

Atrazine Hazards To Fish, Wildlife, And Invertebrates: A Synoptic Review, Ronald Eisler

United States Fish and Wildlife Service: Publications

The herbicide ·atrazine (2-chloro-4-ethylamino-6-isopropylamino-I,3,5- triazine) is the most heavily used agricultural pesticide in North America. In the United States alone, more than 50 million kg (110 million pounds) are applied annually to more than 25 million ha (62 million acres), primarily to control weeds in corn and sorghum. Residues have been detected at phytotoxic concentrations in groundwater, lakes, and streams as a result of runoff from treated fields. Atrazine degrades rapidly, usually by way of hydrolysis, nitrogen dealkylation, and splitting of the triazine ring to less toxic compounds not normally inhibitory to plants and animals. The half-time persistence of atrazine …

G89-923 Windbreak Maintenance And Renovation, Jon Wilson, Mike Kuhns

University of Nebraska-Lincoln Extension: Historical Materials

What are you doing to maintain your windbreak? Is renovation necessary? This NebGuide can help you decide.

Windbreaks are integral parts of many Nebraska farming and ranching operations. They protect man, animals, crops and buildings from cold winter winds, hot summer winds, and deep snows. Windbreaks prevent wind erosion and provide wildlife habitat.

All windbreaks, even well-designed ones, need regular maintenance. Some windbreaks, especially those that are older or neglected, may need more drastic treatment or renovation.

Accumulation Of Lead And Organochiorine Residues In Captive American Kestrels Fed Pine Voles From Apple Orchards, Rey C. Stendell, W. Nelson Beyer, Robert A. Stehn

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Pine voles (Microtus pinetorum) were collected from pesticide-treated orchards in New York (USA) and fed to three captive American kestrels (Falco sparverius) for 60 days to evaluate potential hazards from soil-borne persistent insecticides. Three control kestrels were fed uncontaminated laboratory mice (Mus musculus). The pine voles contained an average of 38 ppm lead, 48 ppm DDE and 1.2 ppm dieldrin (wet weight). The kestrels accumulated sublethal amounts of lead (1 ppm lead wet weight) in their livers. In contrast, DDE and dieldrin accumulated in the tissues and brains of kestrels to toxicologically significant concentrations. …
