The Effects Of Prescribed Fire On The Herbaceous Layer In The Southern Appalachian Mountains., Michael Lee Zimmerman

Electronic Theses and Dissertations

Prescribed fire in the southern Appalachians is a frequently used and controversial forest management practice. Research is limited on the effects of prescribed fire in the mesic southern Appalachians, where many of Tennessee's rare and regionally endemic plant species occur. This study examined the effects of prescribed fire on the herbaceous layer. Field work was conducted on six previously burned sites within the Cherokee National Forest in northeast Tennessee. Complimentary non-burned sites were selected based on similarity of physical characteristics and forest structure. The numbers of herbaceous species and individuals and the total numbers of species and individuals were determined …

Shedding Light Upon The Shadows: An Examination Of The Use Of Voice As Resistance And Reclamation Of The Black Woman From Enslavement To Freedom., Courtney Erin Brooks

Electronic Theses and Dissertations

My research examines the enslaved black woman's reclamation of self through the use of voice and resistance from enslavement into freedom. I argue that the enslaved black woman's voice was one that grew stronger and louder, in an effort to have her story heard, through her attempts of reclamation of self and transition from slave to a free woman. I begin with an introduction to the purpose of my research. Chapter one describes my approach to my research. Chapter two describes the conditions of slavery for black women. Chapter three describes enslaved black women's mechanisms of resistance. Chapter four examinations …

Latex Of Sciadopitys Verticillata (Thunb.) Siebold And Zuccarini: Antibiotic Properties, Phytochemistry, And Inhibition Of Adventitious Rooting Of Stem Cuttings., David Ira Yates

Electronic Theses and Dissertations

Sciadopitys verticillata was subjected to three propagation treatments designed to inhibit coagulation of its latex-like sap at the cut ends of the stem cuttings. Twenty-four hour soaking in water prior to rooting hormone application significantly enhanced production of adventitious roots. Old wood stem cuttings from shade-grown trees rooted at higher proportions than stem cuttings collected from sun-grown trees. Height, age, and place of origin of the source trees were not important factors in successful rooting. Antibacterial activity against some human pathogens and soil bacterial species was detected in latex application trials but the antibiotic activity was not related to the …

Determination Of Cholesterol In Foods By Flow Injection Analysis With Perroxyoxalate Chemiluminescence., Abisake Feleke

Two Types Of Consequentialism, Two Types Of Formalism: Reconsidering Bordenkircher In Light Of Apprendi, Michael M. O'Hear

ExpressO

While the Supreme Court approved of the use of charging threats nearly thirty years ago in Bordenkircher v. Hayes, a more recent line of cases has subtly undermined key premises of that landmark decision. In order to induce guilty pleas, prosecutors might use any of a number of different tactics. A prosecutor might, for instance, charge aggressively in the first instance and then promise to drop the most serious charges in return for a guilty plea to a lesser offense. Bordenkircher addressed the mirror-image of this tactic: the prosecutor filed relatively minor charges at first, but then threatened to pursue …

Mediating Animal Law Matters, Kathy M. Hessler

ExpressO

Animal law matters are slowly making their way through our court system, resulting in some changes in the way we, as a society, view our relationships with non-human animals. Courts are increasingly struggling to reconcile two opposing constructs: the idea that non-human animals are property under the law, and the reality that non-human animals are different from other forms of property. Progress in resolving this tension within the courts is, and will continue to be, slow. The question then arises, what alternative exists?

Mediation is a method increasingly turned to in this country as an alternative to traditional litigation. It …

Stereoselectivity Of 8-Oh-Dpat Toward The Serotonin 5-Ht1a Receptor: Biochemical And Molecular Modeling Study, Joanna Dabrowska, Michal Brylinski

Faculty Publications

The great majority of pharmacological investigations of 5-HT1A receptors' reactivity has been performed using racemic 8-OH-DPAT, therefore the biochemical as well as behavioral profiles of both 8-OH-DPAT enantiomers are not circumstantiated. In the biochemical study capability of racemic 8-OH-DPAT (0.05, 0.1 mg/kg s.c.) and its counterparts R-8-OH-DPAT (0.05, 0.1 mg/kg s.c.) and S-8-OH-DPAT (0.05, 0.1 mg/kg s.c.) to influence 5-HT synthesis rate in rats' prefrontal cortex, hypothalamus, hippocampus and brainstem was evaluated by HPLC/ED technique. Biochemical results are supported by the exhaustive computational study of possible differences between R- and S-enantiomer toward the 5-HT1A receptor. A reliable 3D model of …

Vision-Based Rendering: Using Computational Stereo To Actualize Ibr View Synthesis, Kevin L. Steele

Theses and Dissertations

Computer graphics imagery (CGI) has enabled many useful applications in training, defense, and entertainment. One such application, CGI simulation, is a real-time system that allows users to navigate through and interact with a virtual rendition of an existing environment. Creating such systems is difficult, but particularly burdensome is the task of designing and constructing the internal representation of the simulation content. Authoring this content on a computer usually requires great expertise and many man-hours of labor. Computational stereo and image-based rendering offer possibilities to automatically create simulation content without user assistance. However, these technologies have largely been limited to creating …

Potential Wildlife Control Through Use Of A Plant Growth Regulator, Thomas W. Seamans, Brian E. Washburn

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Habitat management techniques that reduce wildlife use of habitats on and around airports are critical for safe airport operations. Herbaceous vegetation comprises the main habitat type at airports and vegetation can be managed by various methods. The objective of this study was to compare bird and mammal use of grassland habitat managed either by mechanical (mowing) or chemical (plant growth regulator) methods. We monitored vegetation growth, plant community composition, and wildlife activity each week during May – October 2003 in study plots located in Erie County, Ohio. Vegetation was taller (P < 0.01) and denser (P < 0.01) in unmanaged plots than in managed (mowed or growth regulator) plots. Plots sprayed with growth regulator had lower forb/legume cover and higher grass cover than unmanaged or mowed plots. We observed more (P < 0.001) birds (× ± SE) per 5-minute survey on the ground in or perched on vegetation in unmanaged (3.0 ± 0.3) than mowed (1.5 ± 0.2) or growth regulator (1.5 ± 0.3) plots. More (P < 0.001) white-tailed deer were observed in mowed plots (4.3 ± 0.5) than either unmanaged (2.2 ± 0.6) or growth regulator (1.6 ± 0.3) plots. Fifteen small animals were captured in control plots, whereas no animals were captured in managed plots. Applying plant growth regulator did not maintain desired vegetation height and thus is not a costeffective alternative to mowing in plant communities of mixed composition. Managing vegetation height reduced wildlife use of grassland habitats. Removal of forbs and legumes by the growth regulator might explain the reduction in deer use in these plots. Reducing forbs and legumes might also make grasslands less attractive to small mammals. By simplifying herbaceous communities and encouraging plants less desirable to wildlife, it may be possible to reduce the attractiveness of airfields to wildlife species hazardous to aviation.

Canada Goose Populations And Strikes With Civil Aircraft: Positive Trends For Aviation Industry, Richard A. Dolbeer, John L. Seubert

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

Canada goose (Branta canadensis) populations in North America are subdivided into “migrant-goose” and “large-goose” populations. The “large-goose” populations consist primarily of flocks that are non-migratory (hereafter referred to as resident geese). Estimated migrant and resident geese numbers in the four flyways (Atlantic, Mississippi, Central, and Pacific) are based on mid-winter or breeding period counts. The overall Canada goose population increased five fold from 1970 (1.08 million) to 2005 (5.01 million). Most of this overall increase was due to a 15-fold increase in the population of resident geese (from 0.2 to 3.4 million), especially during the 1990s when the …

Real Birds Versus Whirly Birds: Bird Strikes To Civil Helicopters In The Usa, 1990-2005, Richard A. Dolbeer, Sandra E. Wright, Edward C. Cleary

Bird Strike Committee-USA/Canada Joint Annual Meeting: 8th (2006)

To our knowledge, there has been no published analysis of bird strike data specific to helicopters. Our objective was to conduct a comparative analysis of strike reports involving helicopters and fixed-wing aircraft from the Federal Aviation Administration’s Wildlife Strike Database. From 1990-2005, 370 (0.6%) of the 64,734 reported bird strikes to civil aircraft involved helicopters. Of the 370 reported bird strikes involving helicopters, 186 (50%) indicated damage and 67 (18%) indicated substantial damage. In contrast, only 15% of bird strikes with fixed-wing aircraft resulted in damage and 4% resulted in substantial damage. Whereas helicopters accounted for only 0.6% of all …

Evaluating The Wto's Two Step Test For Environmental Measures Under Article Xx, Nita Ghei

ExpressO

There has been considerable dissatisfaction expressed by both free trade proponents and environment activists with respect to the WTO’s exercise of authority on the impact of environmental measures on international trade. The Article first sets out a analytical framework, based on public choice theory, which examines the incentives to implement measures to achieve environmental goals which function effectively as disguised barriers to trade. This is followed by a careful examination of the WTO’s jurisprudence in the area, which suggests that the WTO’s focus on the measure being implemented is correct. Furthermore, the two step test under Article XX, as conceived …

Characterization Of Alternative Cytosolic Forms And Cellular Targets Of Mouse Mitochondrial Thioredoxin Reductase, Anton A. Turanov, Dan Su, Vadim N. Gladyshev

Vadim Gladyshev Publications

Thioredoxin reductase (TR) and thioredoxin (Trx) define a major cellular redox system that maintains cysteine residues in numerous proteins in the reduced state. Both cytosolic (TR1 and Trx1) and mitochondrial (TR3 and Trx2) enzymes are essential in mammals, but the function of the mitochondrial system is less understood. In this study, we characterized subcellular localization of three TR3 forms that are generated by alternative first exon splicing and that differ in their N-terminal sequences. Only one of these forms resides in mitochondria, whereas the two other isoforms are cytosolic. Consistent with this finding, TR3 did not have catalytic preferences for …

The Fisheries Of The Lower Columbia River, 1792 To 1850, Based On Euroamerican Explorer And Fur Company Accounts, Michael A. Martin

Dissertations and Theses

The role of fish in the Native American economy of the lower Columbia River has never been considered in detail. My study focused on the Columbia River from its mouth to the Cascades and the Willamette River from its confluence with the Columbia to Willamette Falls. For this study I asked: How was salmon used? What other fish were important? Where and how were these fish taken and used?

To address these questions, I evaluated historical documents, including explorer's accounts and the administrative records of fur companies dating from the late 1700's through the 1850's. I used fishery data, physical …

Effects Of Anthropogenic Land Use On Odonata In Playas Of The Southern High Plains, K. M. Hernandez, B. A. Reece, N. E. Mcintyre

Western North American Naturalist

Playas are ephemeral wetlands that are the only source of aboveground freshwater in the southern Great Plains, making them of vital importance to aquatic and amphibious animals. Playas are also highly threatened from anthropogenic land use (chiefly agriculture, which decreases hydroperiod through increased sedimentation). We examined community structure of adult odonates (dragonflies and damselflies) in playas differing in the 2 main regional forms of surrounding land use (cropland vs. grassland). Analysis of odonate diversity revealed high overlap between cropland and grassland playas. Traditional species-area theory did not fit observed patterns, as there appears to be a threshold playa size that …

Plant Composition And Erosion Potential Of A Grazed Wetland In The Salmon River Subbasin, Idaho, Kristine N. Hopfensperger, Joan Q. Wu, Richard A. Gill

Western North American Naturalist

Wetlands are dynamic habitats with many unique, important functions including filtering sediments and providing diverse habitats for fish and wildlife. Wetlands in the western United States are particularly important because they offer habitat for a number of protected runs of endangered fish species. Historically, livestock grazing has altered wetland and riparian area form and function by facilitating exotic species invasions, altering spatial heterogeneity of vegetation, and increasing erosion. In this study we examined vegetation structure and erosion potential in a wetland meadow exposed to unregulated grazing along Deer Creek in the Salmon River subbasin, Idaho. We characterized the vegetation composition …

Survival And Reproduction Of Translocated Eastern Wild Turkeys In A Sparsely Wooded Landscape In Northeastern South Dakota, Roger D. Shields, Lester D. Flake

Western North American Naturalist

We studied the survival and reproduction of a newly introduced population of Eastern Wild Turkeys (Meleagris gallopavo silvestris) during 1999 and 2000 to determine the adaptability of this subspecies to a minimally wooded (<10%) region located north of their recorded historic distribution in South Dakota. During 1999 and 2000, the South Dakota Department of Game, Fish and Parks (SDGFP) released 111 female and 25 male turkeys from Iowa and Kentucky onto a study area in northeastern South Dakota. We used radio telemetry to monitor survival and reproduction of the females for 2 years after their initial release. Annual survival for 71 females averaged 67%. Seasonal survival was lowest in fall and highest in winter. Mortality agents included avian and mammalian predators, haying equipment, automobiles, and unknown causes. Nesting rate for the 2 years averaged 93%, and renesting rate of turkeys with failed 1st-nest attempts averaged 45%. Nest success for all nests was 50%, and 62% of females attempting to nest each year were successful in at least 1 attempt. Predation was the primary cause of nest failure during both years. Overall, 72% of brooding females successfully raised ≥1 poult to 4 weeks post-hatch while individual poult survival to 4 weeks post-hatch averaged 36%. Despite <10% woodland cover, Eastern Wild Turkeys appeared to thrive in a glacial escarpment topography north of their historic range in the northern plains.

Habitat Affinities Of Rodents In Northeastern Nevada Rangeland Communities, J. Kent Mcadoo, Mack R. Barrington, Mark A. Ports

Western North American Naturalist

From May 1978 through September 1980, baseline data for rodent populations were collected by livetrapping in the Saval Ranch area of northeastern Nevada. The objectives of this study were to determine species composition and relative abundance of rodents for the various range sites. The 3 most abundant and uniformly distributed species were deer mice (Peromyscus maniculatus), Great Basin pocket mice (Perognathus parvus), and least chipmunks (Neotamias minimus). Relative abundance indices and densities reported for most species were similar to those reported in other multiyear studies at similar sites. The composition and relative abundance / …

Early Brood-Rearing Habitat Use And Productivity Of Greater Sage-Grouse In Wyoming, Kristin M. Thompson, Matthew J. Holloran, Steven J. Slater, Jarren L. Kuipers, Stanley H. Anderson

Western North American Naturalist

Populations of Greater Sage-Grouse (Centrocercus urophasianus) have been declining throughout their range since the 1960s. Productivity, which includes production and survival of young, is often cited as a factor in these declines. We monitored radio-equipped Greater Sage-Grouse at 3 sites in western Wyoming to assess early brood-rearing habitat use (through 14 days post-hatch) and productivity. Logistic and linear regression analyses with Akaike's Information Criterion were used to evaluate early brooding habitat use and to examine relationships between productivity and vegetation, insect size and abundance, and weather parameters. Females with broods were found in areas with greater sagebrush canopy …

Influence Of Fire And Juniper Encroachment On Birds In High-Elevation Sagebrush Steppe, Anna C. Noson, Richard A. Schmitz, Richard F. Miller

Western North American Naturalist

We examined relationships between high-elevation sagebrush (Artemisia spp.) steppe habitats altered by prescribed fire and western juniper (Juniperus occidentalis) encroachment on breeding distributions of Brewer's Sparrows (Spizella breweri), Vesper Sparrows (Pooecetes gramineus), Green-tailed Towhees (Pipilo chlorurus), and Sage Thrashers (Oreoscoptes montanus) on Steens Mountain in southeastern Oregon. In 2000 we conducted fixed-radius point count surveys at 172 sites encompassing burned and unburned sagebrush habitat and a range of juniper densities. For each bird species we developed habitat models using local variables measured in the field and landscape variables derived …
