Deer On Airports: An Accident Waiting To Happen, Sandra E. Wright, Richard A. Dolbeer, Andrew J. Montoney Jan 1998

Deer On Airports: An Accident Waiting To Happen, Sandra E. Wright, Richard A. Dolbeer, Andrew J. Montoney

Vertebrate Pest Conference Proceedings: 18th (1998)

The authors analyzed data on civil aircraft strikes with wild ungulates (deer [Odocoileus spp.], elk [Cervus canadensis] and moose [Alces alces]) in the U.S. from the Federal Aviation Administration (FAA) Wildlife Strike Database and the National Transportation Safety Board (NTSB) Aviation Accident Database for 1983 to 1997. Prior to 1991, the FAA Form 5200-7 for reporting strikes was designated solely for bird strike data, thus, strike reports for non-avian species prior to 1991 are underrepresented. A total of 343 ungulate strikes was reported, 48 from 1983 to 1990 and 295 from 1991 to 1997. Forty-four …


Comparison Of White Mineral Oil And Corn Oil To Reduce Hatchability In Ring-Billed Gull Eggs, Patrica A. Pochop, John L. Cummings, Christi A. Yoder, John E. Steuber Jan 1998

Comparison Of White Mineral Oil And Corn Oil To Reduce Hatchability In Ring-Billed Gull Eggs, Patrica A. Pochop, John L. Cummings, Christi A. Yoder, John E. Steuber

Vertebrate Pest Conference Proceedings: 18th (1998)

Oiling eggs is a potential management method for controlling nuisance or depredating populations of ring-billed gulls, Canada geese, and other bird species. However, no registration for an oiling compound currently exists with the Environmental Protection Agency. Efficacy data were collected for white mineral oil and corn oil to reduce the hatchability of ring-billed gull eggs. Egg failure was 99% in corn oil, 96% in white mineral oil, and 35% in control eggs. Most treated eggs that hatched were treated early in the incubation period, 1 to 8 days after clutch completion. A Wildlife Service Technical Note on the use of …


Fertility Control In Coyotes: Is It A Potential Management Tool?, Thomas J. De Liberto, Eric M. Gese, Frederick F. Knowlton, J. Russell Mason, Michael R. Conover, Lowell Miller, Robert H. Schmidt, Michael K. Holland Jan 1998

Fertility Control In Coyotes: Is It A Potential Management Tool?, Thomas J. De Liberto, Eric M. Gese, Frederick F. Knowlton, J. Russell Mason, Michael R. Conover, Lowell Miller, Robert H. Schmidt, Michael K. Holland

Vertebrate Pest Conference Proceedings: 18th (1998)

Fertility control in wildlife is emerging as a potential management tool. Published research on feral horses, deer, rodents, and rabbits suggest an effective agent producing reversible infertility in these species could be developed. Furthermore, anecdotal reports suggest that infertility can be induced in a greater array of species. In this paper, the authors review methods of fertility control being studied for application in wildlife and focus on their studies designed to evaluate the effectiveness of fertility control agents in coyotes (Canis latrans). Immunocontraception using porcine zona pellucida (PZP) is currently the most promising method of fertility control in …


Tracing The History Of Blackbird Research Through An Industry's Looking Glass: The Sunflower Magazine, George M. Linz, H. Jeffrey Homan Jan 1998

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 Jan 1998

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 Jan 1998

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 …


Managing Island Biotas: Brown Treesnake Control Using Barrier Technology, Gad Perry, Earl W. Campbell Iii, Gordon H. Rodda, Thomas H. Fritts Jan 1998

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 …


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 Jan 1998

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 …


Review Of Bird Repellents, Larry Clark Jan 1998

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.

Apparatus And Method For Detection And Concentration Measurement Of Trace Metals Using Laser Induced Breakdown Spectroscopy, Dennis R. Alexander

Department of Electrical and Computer Engineering: Faculty Publications

A method and apparatus for in situ detection and concentration measurement of trace elements in an analysis Sample is disclosed. The invention uses laser induced breakdown spectroscopy (LIBS) wherein femtosecond pulsed laser energy is employed to produce the plasma. The femtosecond pulsed laser energy is focused on the analysis Sample to produce the plasma and the resulting emission is delivered for spectral analysis. Because the method and apparatus of the present invention allow breakdown of the analysis Sample without propagation of energy to the Sample-air interface, a plasma is produced that consists essentially of Sample materials without being contaminated by …

What Does Problem-Based Learning Look Like In Classrooms?, Linda Torp, Sara Sage Jan 1998

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.

Disease And Water Supply: The Case Of Cholera In 19th Century Iran, Amir A. Afkhami Jan 1998

Disease And Water Supply: The Case Of Cholera In 19th Century Iran, Amir A. Afkhami

Medicine Faculty Publications

This paper explores why Iran was a particularly fertile ground for repeated visitation of cholera in the 19th century. Along with certain unique Iranian cultural and religious factors, the author demonstrates how Iranian urban ecology, particularly the qanat system, contributed to the fatal spread of the epidemic. These multi-faceted conditions, the author concludes, resulted in distinct modes of disease transmission and mortality in Iran.

A Study Of Morphological Character Displacement In The Social Wasp, Polistes Fuscatus, Noah K. Whiteman Jan 1998

A Study Of Morphological Character Displacement In The Social Wasp, Polistes Fuscatus, Noah K. Whiteman

Honors Theses, 1963-2015

According to competition theory, when a population lives sympatrically with competitor populations, the variation in morphological characteristics within each population should be reduced. In allopatric populations, the variation in these characteristics should increase. I examined morphological character displacement in Polistes fuscatus populations in a north-south latitudinal gradient across the United States. P. fuscatus is sympatric with at least five other congeneric species in U.S. Gulf Coastal areas. As latitude increases, the number of species is reduced, and only P. fuscatus is found in Minnesota. Therefore, body size variation of P. fuscatus in Minnesota was predicted to be broader than the …


The Effects Of Pesticides On The Common Leopard Frog, Rana Pipiens: A Hematological Study, Jennifer L. Loos Jan 1998

The Effects Of Pesticides On The Common Leopard Frog, Rana Pipiens: A Hematological Study, Jennifer L. Loos

Honors Theses, 1963-2015

Deformed frogs are appearing frequently in the wild. Speculations of the cause of deformities are pesticides, chemicals, viruses, parasites, and ultra-violet light. I am examining the blood for chromosome fragments, micronuclei, which result in a loss of genetic material during replication and could produce deformities. Some studies on amphibians show that organisms exposed to various chemicals have a higher incidence of micronuclei than organisms without chemical exposure. By studying the blood of the common leopard frog tadpoles, Rana pipiens, exposed to the herbicide atrazine I attempted to discover if atrazine significantly alters the number of micronuclei in the red blood …


Circadian Rhythms Of Body Temperature And Metabolic Rate In The House Sparrow (Passer Domesticus), Pericles P. Regas Jan 1998

Circadian Rhythms Of Body Temperature And Metabolic Rate In The House Sparrow (Passer Domesticus), Pericles P. Regas

Honors Theses, 1963-2015

Birds maintain a fairly high body temperature (Tb) compared to most mammals. In order to maintain a high Tb birds must have a high metabolic rate. High daytime energy expenditures are decreased during the night by lowering Tb. In this experiment daily Tb in house sparrows (Passer domesticus) were determined by telemetry methods. Tb (n=6) showed a decrease of 3.00 C from daytime to night time. The average daytime Tb was 42.7 C and night time was 39.7 C. Oxygen consumption (VO2) was measured in an open flow metabolism system. Metabolic rate had a …


Bumblebee Pollination Ecology In A Restored Prairie Ecosystem: Foraging Rates, Pollen Sources, And Resource Partitioning, Mary Margaret Price Jan 1998

Bumblebee Pollination Ecology In A Restored Prairie Ecosystem: Foraging Rates, Pollen Sources, And Resource Partitioning, Mary Margaret Price

Honors Theses, 1963-2015

A major factor in evaluating the success of prairie, and other, ecosystem restoration projects is a determination of the extent to which pollinator communities have been reestablished along with the flora. I studied bumblebee pollination ecology of a prairie restoration project in central Minnesota to determine the extent to which the several bumblebee species were interacting with the reestablished native prairie flora and with each other to reestablish a viable pollinator community. This was accomplished by determining if the bumblebees are majoring, if they are majoring on the native prairie plant species conservation efforts are attempting to restore, and if …


The Components Of Feeeding Behavior In The Rotifer Asplanchna Herricki: Attack, Capture, Consumption, Selectivity, And Trophi Morphology, Tony Baumert Jan 1998

The Components Of Feeeding Behavior In The Rotifer Asplanchna Herricki: Attack, Capture, Consumption, Selectivity, And Trophi Morphology, Tony Baumert

Honors Theses, 1963-2015

The rotifer Asplanchna herricki (A. herricki) is an integral predatory species impacting rotifer and algae populations of fresh water lake habitats. In order to determine the feeding behavior and mechanism of A. herricki, stomach content analysis was performed and predator/prey interactions were observed. A. herricki encountered prey randomly, only attacking after physical contact of the prey with the corona. It was found that A. herricki prefers small rotifer prey as opposed to algae. Algae such as Volvox and Pediastrum appeared to deter ingestion due to size or shape. Rotifers such as Keratella cochlearis, Brachionus patulus, …


Synthesis And Characterization Of A Trypsin Inhibitor, Eric L. Schneider Jan 1998

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 …
