Tracing The History Of Blackbird Research Through An Industry's Looking Glass: The Sunflower Magazine, George M. Linz, H. Jeffrey Homan

Vertebrate Pest Conference Proceedings: 18th (1998)

The Sunflower magazine, the voice of the National Sunflower Organization, featured articles in January 1978 and December 1996 that began with these words, "If Old King Cole was a merry old soul, it was probably because he had only four and twenty blackbirds to contend with, and they were all out of commission!" This quotation captures the sentiments of sunflower growers, who have identified blackbirds as a major production problem since the 1960s. The National (formerly Denver) Wildlife Research Center, a unit within the U.S. Department of Agriculture's Animal and Plant Health Inspection Service Wildlife Services, is charged with both …

The Impact Of Timber Management On The Phytochemicals Associated With Black Bear Damage, Dale L. Nolte, Bruce A. Kimball, Georg J. Ziegltrum

Vertebrate Pest Conference Proceedings: 18th (1998)

Black bears forage on Douglas-fir vascular tissue in the spring, and this behavior can be severely detrimental to the health and economic value of a timber stand. Foraging is selective in that not all stands are damaged and, within a stand, one tree may be stripped while its neighbor is ignored or minimally sampled. A series of studies was conducted to assess whether bear selectivity is affected by chemical constituents within vascular tissue, and whether these constituents are affected by silvicultural practices. The results are interpreted to identify forest practices that may alleviate damage, or at least predict where damage …

Wildlife Information Sources And Search Methods On The Internet, Diana L. Dwyer

Vertebrate Pest Conference Proceedings: 18th (1998)

Vertebrate pest damage information is pulled from a variety of disciplines ranging from wildlife management to psychology. The Internet has opened the door to what seems to be an unending number of information sources. Researchers can become overwhelmed by the choices and different levels of information available. The correct use of search engines and a checklist of criteria to evaluate the quality of information obtained can help to eliminate the extraneous information and make the time spent on the Internet more productive. There are a large number of wildlife, biology, environmental, and other related sites that are especially useful to …

Potential Bird Repellents To Reduce Bird Damage To Lettuce Seed And Seedlings, John L. Cummings, Patricia A. Pochop, Christi A. Yoder, James E. Davis Jr.

Vertebrate Pest Conference Proceedings: 18th (1998)

The authors evaluated the effectiveness of ReJeX-iT® AG-145, Mesurol®, activated charcoal, lime, and fipronil to reduce homed lark damage to lettuce seeds and seedlings. In Experiment 1, homed larks consumed significantly more feed mixture (50:50 grains and lettuce seed) than untreated clay-coated lettuce seed in a three-day choice-test. In Experiment 2, where clay-coated lettuce seed was treated with ReJeX-iT® AG- 145, Mesurol®, activated charcoal, or lime, there was no significant difference in consumption of untreated clay-coated lettuce seed and treated clay-coated lettuce seed. Homed larks consumed insignificant amounts of all seed treatments including untreated coated lettuce seed. In this experiment …

Managing Island Biotas: Brown Treesnake Control Using Barrier Technology, Gad Perry, Earl W. Campbell Iii, Gordon H. Rodda, Thomas H. Fritts

Vertebrate Pest Conference Proceedings: 18th (1998)

The brown treesnake (Boiga irregularis), accidentally introduced to the previously snake-free U.S. island of Guam after World War 11, decimated the island's naive wildlife. Today, it periodically stows away on craft going to other islands where the ecological damage may be repeated. Barriers offer an effective tool for keeping the snakes out of areas from which they can disperse off-island, as well as sites identified as critical for the protection of human health, conduct of economic activity, or conservation of endangered species. The authors have developed a variety of barrier designs which repulse at least 95% of snake …

Effects Of Taste Stimuli (Quinine And Sucrose) In Pelleted Granulated, And Wax Block Baits On Feeding Preferences Of Northern Pocket Gophers (Thomomys Talpoides), Stephen A. Schumake, Geraldine R. Mccann

Vertebrate Pest Conference Proceedings: 18th (1998)

A two-choice, taste preference study was conducted using 18 northern pocket gophers to evaluate pelleted sorghum, granulated sorghum, and wax block baits containing either 0.01 to 0.05 % quinine or 0.10 to 5.0 % sucrose. Bait consumption was significantly higher across treatments (P≤.001) for granulated sorghum, followed by pelleted sorghum, and wax blocks. Gophers also showed a high frequency of moving the granulated bait in their cheek pouches to be deposited at alternate locations within their cages. Although increasing sucrose concentration did not produce significantly (P ≥.10) enhanced consumption for any of the baits, a trend toward increasing preference with …

Evaluation Of Acrolein As A Fumigant For Controlling Northern Pocket Gophers, George H. Matschke, Geraldine R. Mccann, Rebecca A. Doane

Vertebrate Pest Conference Proceedings: 18th (1998)

Baker Performance Chemical Incorporated entered into a cooperative agreement with the National Wildlife Research Center to evaluate acrolein as a fumigant for controlling northern pocket gophers (Thomomys talpoides). In October 1996, a 44.5 ha (110 acre) irrigated alfalfa hay field was selected as the study site in Franklin County, Washington. Eight treatment units (TUs), six fumigated and two control, were established on the study site. On the six fumigated TUs, 58.9% of the sample plots were inactive, whereas, all sample plots (100%) on the two control TUs were active. The 58.9% mean reduction in pocket gopher activity on …

Mammal Repellents: Options And Considerations For Development, J. Russell Mason

Vertebrate Pest Conference Proceedings: 18th (1998)

Repellents include chemical substances, visual displays, and sonic and ultrasonic deterrent systems. The use of electric shock also can be considered as a repellent category. Each of these categories is discussed, together with their respective utilities, constraints on their usefulness, and possibilities for future development. Economic considerations that may impede or expedite the development of new strategies are presented. Repellent effectiveness depends upon a complex of variables, including the palatability of protected and alternative foods, weather conditions, and the number of animals causing problems. Invariably, repellents are most useful when used as components of integrated pest management strategies

Evaluation Of Electronic Frightening Devices As White-Tailed Deer Deterrents, Jerrold L. Belant, Thomas W. Seamans, Laura A. Tyson

Vertebrate Pest Conference Proceedings: 18th (1998)

The authors evaluated the effectiveness of the motion-activated Usonic Sentry (with and without strobe), motion-activated Yard Gard, and Electronic Guard for deterring white-tailed deer (Odocoileus virginianus) from preferred feeding areas from February to April 1996. Two four-week experiments were conducted, monitoring deer use (number of intrusions and corn consumption) at eight feeding stations in a 2,200 ha fenced facility in northern Ohio with high deer densities (≥ 38/km²). During these experiments, one of the devices was positioned at each of four sites. The mean (± SE, n = 4) daily number of deer intrusions at feeding …

Development Of Seed Treatments To Control Blackbirds, Michael L. Avery, David Decker, John S. Humphrey

Vertebrate Pest Conference Proceedings: 18th (1998)

Bird repellents to protect seeds are a potentially important aspect of integrated vertebrate pest management strategies. Yet, there currently are no repellents registered for seed treatment uses. This is due not to lack of effective candidate compounds, but to monetary and regulatory constraints that inhibit commercialization of promising compounds. Two examples of this dilemma are methiocarb and anthraquinone, each of which has considerable potential for bird repellent uses and each of which faces considerable registration hurdles as prospective seed treatment compounds. A concerted, coordinated effort among private industry, producer groups, and state and federal agencies may be the best strategy …

The Bait Surcharge Program: Research Improves Zinc Phosphide Use For Vole Control In Alfalfa, Ray T. Sterner

Vertebrate Pest Conference Proceedings: 18th (1998)

This paper describes several unexpected benefits of rodenticide-registration research funded by The California Bait Surcharge Program. An enclosure-type study was conducted to determine efficacy of single, pre- and test-bait broadcasts (10 lb./ac.) of 0% and 2% zinc phosphide (Zn₃P₂, CAS #1314-84-7) steam-rolled-oat (SRO) groats to control voles (Microtus spp.) in alfalfa (Medicago sariva). Unexpected research spinoffs resulted from the use of: 1) eight randomly-located, sieved-dirt plots per enclosure to monitor bait distribution, bait removal, and rodent/avian (non-target) activity; 2) a bait-weathering plot and bait-sample analyses to monitor Zn₃P₂ biodeterioration; and …

The Development Of An Integrated Pest Management Plan For Roof Rats In Hawaiian Macadamia Orchards, Earl W. Campbell Iii, Ann E. Koehler, Robert T. Sugihara

Vertebrate Pest Conference Proceedings: 18th (1998)

Roof rats (Rattus rattus) damage an estimated 5 to 10% of the developing nut crop in Hawaiian macadamia (Macadamia integrifolia) orchards. Relevant aspects of roof rat biology in macadamia orchards have and continue to be studied with the ultimate goal of developing an ecologically sound and cost-effective integrated pest management plan. The field component of a two-year study of roof rat populations in macadamia orchards has recently been completed. The goal of this study is to clarify the relationship between roof rat seasonal abundance, macadamia flowering, and nut production on five orchards in three regions on …

Population Dynamics: The Foundation Of Wildlife Damage Management For The 21st Century, Richard A. Dolbeer

Vertebrate Pest Conference Proceedings: 18th (1998)

To justify and defend lethal or reproductive control programs to solve vertebrate pest problems, wildlife biologists must have a sound understanding of the population status and dynamics of the problem species. Models are essential to project how populations will respond to proposed management actions, providing a scientific foundation to counter the emotional debates that often arise. Four population models (PM1 to PM4) for predicting population responses are described. PM1 and PM2 explore the relative efficacy of reproductive and lethal control for vertebrate species over 10-year intervals. PM3 simulates population responses to actual management actions through 10-year intervals. PM4 simulates population …

Review Of Bird Repellents, Larry Clark

Vertebrate Pest Conference Proceedings: 18th (1998)

Despite a general perception that there is an abundance of nonlethal control technologies, the fact remains that there are fewer registered products and active ingredients for repellents in the U.S. than there were 10 and 20 years ago. This review discusses the technical issues relating to the discovery, formulation, and delivery of chemical repellents, and suggests future avenues of research that would improve our ability to develop effective chemical repellents.

Counseling Groups For High School Students, Rachel E. Williams

Graduate Research Papers

Groups were first established in the public schools in the early 1900s. At this time, the group provided an environment in which to learn life skills and values rather than focusing on the group process (Gladding, 1995). There was a growth of groups in select schools during the 1910s, although the focus continued to be on individual counseling. In the 1930s, the focus of groups was on vocational and personal themes. They were often the responsibility of homeroom teachers. In these groups, the teacher was responsible for establishing friendly relationships and developing the right attitudes toward school, home, and the …

What Does Problem-Based Learning Look Like In Classrooms?, Linda Torp, Sara Sage

Publications & Research

WHETHER THINKING ABOUT THE UNIVERSE, THE AMBIGUities of life, or the wonders of learning—educators realize that the whole is so much more than any collection of parts. As they work with learners of all ages, they constantly strive to create experiences that are holistic and connected. Ones that enable students to tackle the complexities facing us as citizens in a global community, as well as in everyday situations. Ones that reveal a need to be open-minded and adaptable. Ones that consider the interrelatedness of systems, both natural and contrived.

Data Mining In Electronic Media Usage Statistics: A Case Study Of Knowledge Discovery In Databases, Peter J. Lindquist

Honors Theses, 1963-2015

As databases grow larger, analysts are turning to computers to help them analyze the massive amounts of data their computers have collected. As the difference between having data and having useful information becomes more clear, different methods of using computers to analyze data are becoming available. Knowledge Discovery in Databases (KDD) is a general methodology for preparing the data, using software algorithms to discover new patterns or relationships in the data, and integrating the results back into the system. The KDD methodology is explained and hypothetically applied to usage statistics generated by the CSB/SJU Libraries Internet resources. Examples are drawn …

Validating A Health Questionnaire For Predicting Neuropathy In Patients With Insulin-Dependent Diabetes Mellitus, Matthew J. Maurer

Honors Theses, 1963-2015

Questionnaires are a cost-effective method for screening large numbers of people for health problems. More expensive clinical follow-up can focus on people whose responses to the questionnaire suggest they are most at risk. To my knowledge, no questionnaire has ever been developed to screen for neuropathy in diabetics. Using the questionnaire developed by Dr. Peter Cavanagh and Dr. Robert Van Deursen at the Center for Locomotion Studies (CELOS) at Penn State University, I was able to create a model from the questionnaire that predicts the presence of neuropathy.

The Synthesis And Characterization Of Monometallic And Bimetallic Pd-Pnp Complexes, Lorinda Asmus

Honors Theses, 1963-2015

The bridging ligand, 2-[bis(diphenylphosphino)methyl]pyridine (PNP), is ideal for synthesizing mono- and bi-metallic catalysts due to its potential to be bidentate (P-P or P-N) or tridentate and its ability to bind to one or more metals. Three Pd-PNP complexes, [Pd(PNP)₂]⁺² (1) and two complexes resulting from the removal of one or two methine pronouns (2 and 3), have been synthesized. The removal of one methine proton changes the PNP bidentate binding mode. In complex 1 and 3, the two PNP ligands are P-P bound. However, upon the removal of one methine proton, one …

Synthesis And Characterization Of A Trypsin Inhibitor, Eric L. Schneider

Honors Theses, 1963-2015

Inhibitors of biological enzymes are frequently produced by mimicking the molecular structure of the enzyme's natural substrate. Because of the extensive studies that have already been performed on the trypsin enzyme, its natural substrates and its mode of interaction with them are well understood. By finding an easily synthesized molecule to inhibit the trypsin enzyme, college level laboratory experiments could be designed and integrated into organic chemistry and biochemistry courses. In this project, a possible trypsin inhibitor molecule, 4-fluorobenzylaimine, was chosen based on its similarity to the natural trypsin substrates and because it has been predicted through computational studies to …

Heraldry And Programming Languages: The Complexity Of Natural Languages Examined Through The Parsing Of The Heraldic Blazon, Hans A. Mersinger

Honors Theses, 1963-2015

The idea of programming computers to understand human speech and written text has been the dream, even the Holy Grail, of computer scientists and many others, since before the first computers where created. Computers in countless movies and television shows have been able to understand, and therefore interact with, the humans around them but until recently this possibility has been pure science fiction. By studying, and then attempting, the methods of parsing the heraldic language, one hopes to show some of the methods that are used to remove the ambiguity in natural languages that hamper their parsing. Given time, I …

Counting Cards: Combinatorics, Group Theory, And Probability In War, Angela J. Chappell

Honors Theses, 1963-2015

My project involved taking a look at the card game War, searching for patterns which develop in the game, and then looking for Mathematical explanations for those patterns. The project began when my advisor, Professor Marc Brodie, was playing War with his children and began to notice patterns and ask questions about them. The questions I set out to answer were: What is the probability of playing a game of war in which a loop develops? If we know the size of the deck we are using, can we determine what loop lengths are possible? How are cards cycling between …
