The digestive tracts of 48 snow geese (38 lesser snow geese and 10 Ross’s geese) were collected from 4 February to 3 March, 2012, in Raymond, Illinois. Eight helminth taxa (two species of Trematoda, four species of Nematoda, and two species of Cestoda) were recovered. Five of the eight helminth taxa were common in both species …

Use Of Distiller Grains In Alternative Beef Heifer Systems, Jared M. Mracek

Department of Animal Science: Dissertations, Theses, and Student Research

Every year, producers select replacement heifers with the intention that these heifers are the future of their cow herd. Producers normally select replacement heifers at weaning based on weight and structure. When selecting heifers at weaning, producers risk not selecting heifers that would be productive cows based on their criteria. By delaying the selection of replacements, it will allow producers to increase the opportunity to thoroughly evaluate replacement prospects. The corn dry-milling industry produces byproducts that can be economical supplements to growing cattle on forage. An experiment evaluated an alternative heifer system utilizing distiller grains as an energy source to …

Chemical Control Of Rootstock Regrowth In Grafted Watermelon And Its Effects On Plant Growth And Development, Shawna Daley

All Theses

High, year-round demand, increased production intensity without crop rotation, and the loss of Methyl Bromide as a soil fumigant, results in unfavorable soil conditions with increased soil pathogen populations for growing watermelon [Citrullus lanatus (Thunb) Matsum and Nakai]. Grafting watermelon onto resistant rootstocks provides successful control of soil-borne pathogens, and could increase yield and fruit quality; however, the high production costs, especially from labor, involved in grafted transplant production, has prevented the adoption of grafted watermelon use in the United States. Much of the labor is required for meristematic regrowth control, which can cause abortion of the scion and competition …

The Leconte Lodge: A Lens For The Evolution And Development Of The Great Smoky Mountains National Park, Lindsay D. Lanois

All Theses

Officially established in 1934, the Great Smoky Mountains National Park originated as part of a widespread cultural trend towards outdoor recreation, national tourism, and the federal government's assumption of responsibility for land conservation. However, the area of Tennessee and North Carolina selected by the federal government for the national park was not a purely unsettled landscape. Not only did the land serve as home to approximately ten permanent agricultural communities, but it also featured several hotels and lodges inspired by the burgeoning twentieth-century tourism industry. Beginning as a rudimentary hiking cabin constructed in 1925 and evolving throughout the 1930s, the …

The Role Of Amp-Activated Protein Kinase (Ampk) In Regulating The Early Stages Of Acute Pancreatitis, Mohamed Shitia

Honors Scholar Theses

Acute pancreatitis is an inflammatory disease that is initiated by the activation and retention of digestive zymogens inside pancreatic acinar cells (acini). It is proposed that adenosine monophosphate-activated protein kinase (AMPK) regulates early responses of acute pancreatitis in acini. A recent study shows that induction of experimental pancreatitis in isolated rat acini with supraphysiologic cerulein (orthologue of cholecystokinin) increases intracellular zymogen activation, but decreases AMPK levels. Furthermore, in vitro pharmacologic stimulation of AMPK reduces zymogen activation, having a protective effect. In this study, the effectiveness of two AMPK activators was examined in two separate in vivo pancreatitis models. In the …

Solving The Obesity Problem One Bite At A Time: A Review Of Interventions, Sally Catherine Davis

Honors Theses

Resource limitations contribute to obesity in southern rural populations. An examination of published research provides evidence related to factors that lead to obesity and to related health consequences. Resource limitations in southern rural areas include a lack of access to healthy foods, a lack of safe areas to exercise or fitness equipment, and a lack of funding to promote the hiring of adequate numbers of healthcare workers to implement prevention programs and treat obesity related diseases. An investigation of obesity rates in Mississippi and Louisiana demonstrate that high rates of obesity exist. Through an exploration of published interventions in both …

Study Of The Function Of The Mold Specific Gene Ms95 In Dna Repair In The Pathogenic, Dimorphic Fungus Histoplasma Capsulatum, Erin M. Smith

Honors Theses

Histoplasma capsulatum (Hc) is a dimorphic fungus that is the etiologic agent of the respiratory infection Histoplasmosis that is mediated by a shift from the mold phase to the pathogenic yeast phase. Genes have been identified that are specific to the mold or yeast phase in order to study the molecular biology of this shift. MS95 was identified in a subtractive cDNA library that was enriched for mold-specific genes, and has been found to be homologous to the DNA damage-responsive gene DDR48, which functions in DNA repair in Saccharomyces cerevisiae.

Carbon And Nitrogen Analysis To Determine Competitive Outcome For Three Species Of Container Mosquitoes, John Lloyd Martin

Honors Theses

It is well documented that intense larval competition exists between species of container mosquitoes. Two of the main genera of mosquitoes found to inhabit containers are Aedes and Culex. This study sought to determine the effects that different detritus treatments and larva ratios would have on carbon and nitrogen content, mass, and survival of larvae of various species. The species used in this experiment were Aedes albopictus, Aedes aegypti and Culex quinquefasciatus. I hypothesized that Ae. albopictus would be more efficient in acquiring nitrogen then the competitor species Ae. aegypti and Cx. quinquefasciatus. Thus, I expected Ae. albopictus to …

Estimating Nitrogen Fixation Rates, Importance, And Short-Term Efficiency In Small, Temperate Reservoirs Using Delta15n Techniques, Bryant Christopher Baker

Graduate Theses and Dissertations

Nitrogen (N2) fixation can give certain species of cyanobacteria a competitive advantage in lake and reservoir phytoplankton. These species of cyanobacteria, along with others that cannot fix N2, can form toxic compounds that impair water quality when present in high concentrations. N2 fixation rates may be substantial in small (< 1.0 km2), temperate reservoirs since these systems experience thermal stratification and often nitrogen (N) limitation throughout a substantial proportion of the year. However, the effects of N2 fixation on N cycling, alleviation of short-term N limitation, and water quality are not well-understood. A mesocosm experiment and ecosystem-scale observational study were conducted to 1) determine the efficiency of N2 fixation under varying N relative to phosphorus (P) supply, 2) examine the effects of N2 fixation on autotrophic biomass accumulation and microcystin production, and 3) measure N2 fixation rates and importance to autotrophic N demand and zooplankton N assimilation. Results of the mesocosm experiment indicated that N2 fixation was increased at low N:P supply under high P. However, N2 fixation was inefficient at alleviating N limitation when fixed N was the primary source of N. Additionally, microcystin production occurred only at high N:P supply when N2 fixation was low, indicating that reducing external N inputs may have a positive effect on water quality. Results of whole-reservoir determination of N2 fixation using seston δ15N natural abundances indicated that N2 fixation rates throughout the warm season were substantial and influenced by water temperature. Annual N2 fixation rates ranged from 2.2 - 6.6 g N m-2 yr-1, and contributed up to 19% of the annual autotrophic N demand. Zooplankton were assimilating fixed N in most of the study reservoirs, representing a possible mechanism of ecosystem fixed N retention. Collectively, these results suggest that N2 fixation plays a substantial role in N cycling in small, temperate reservoirs, but likely cannot alleviate short-term N limitation.

Efficacy Of Rice Insecticide Seed Treatments At Selected Nitrogen Rates For Control Of The Rice Water Weevil, Lissorhoptrus Oryzophilus Kuschel, Mallory Elise Everett

Graduate Theses and Dissertations

Seed-applied insecticides are the standard control method used to prevent rice water weevil (Lissorhoptrus oryzophilus Kuschel) injury to rice (Oryza sativa L.) roots, and often results in greater yields than rice that receives no seed-applied insecticide. Yield increases from seed-applied insecticides often occur even when insect pressure is low and should not cause yield loss. The research objective was to evaluate the effect of urea-nitrogen rate and seed-applied insecticide on number of rice water weevil larvae, nitrogen uptake and rice grain yield. Six trials were conducted at the Pine Tree Research Station (PTRS) and the Rice Research Extension Center (RREC) …

Queer Tastes: An Exploration Of Food And Sexuality In Southern Lesbian Literature, Jacqueline Kristine Lawrence

Graduate Theses and Dissertations

Southern identities are undoubtedly influenced by the region's foodways. However, the South tends to neglect and even to negate certain peoples and their identities. Women, especially lesbians, are often silenced within southern literature. Where Tennessee Williams used literature to bridge gaps between gay men and the South, southern lesbian literature severely lacks a traceable history of such connections. The principal objective of this thesis is to explore the ways in which southern lesbians manipulate food metaphors to describe their sexual desires and identities. This thesis only begins to lay out a history of southern lesbian literature as many lesbian writers …

Impact Of Early Infestation Of Two-Spotted Spider Mites (Tetranychus Urticae) On Cotton Growth And Yield, Luis Orellana Jimenez

Graduate Theses and Dissertations

Two-spotted spider mites (Tetranychus urticae Koch, 1836) are pests of vegetables, ornamentals, and row crops around the world. Two-spotted spider mites have become an important long-season pests of cotton, causing injury to cotton from an early vegetative stage. In the past eight years, Arkansas cotton acreage treated for spider mites has more than doubled and most of the increase has been attributed to early season infestations. Yield losses of up to 30% have been observed in other studies where spider mite infestation started at third true leaf. Because of the apparent change in this pest's population dynamics, particularly at …
