Effects Of Organic And Conventional Agricultural Practices On Soil Microbial Communities And Molecular Detection Of Soil Borne Disease, Holli K. Milner

College of Graduate Studies: Theses & Dissertations

Agricultural practices affect soil microbial communities and health through the input of pesticides, herbicides, fertilizers, and cycling of crop rotation. By examining the microbial community structure, we analyzed how microbial species respond to the environment that individual farms create. Early detection of soil borne disease is essential for agricultural success. However, monitoring incidence of disease based on plant growth response to pathogenic inoculation may not reveal the amount of pathogenic DNA in soil. A comparative study of tomato production systems was conducted by analysis of soil microbial community structure from four farms in Southeast Georgia for the years 2012 and …

De Novo Transcriptome Assembly From Fat Body And Flight Muscles Transcripts To Identify Morph-Specific Gene Expression Profiles In Gryllus Firmus, Neetha Nanoth Vellichirammal, Anthony J. Zera, Rudolf J. Schilder, Cody Wehrkamp, Jean-Jack M. Riethoven, Jennifer A. Brisson

School of Biological Sciences: Faculty Publications

Wing polymorphism is a powerful model for examining many aspects of adaptation. The wing dimorphic cricket species, Gryllus firmus, consists of a long-winged morph with functional flight muscles that is capable of flight, and two flightless morphs. One (obligately) flightless morph emerges as an adult with vestigial wings and vestigial flight muscles. The other (plastic) flightless morph emerges with fully-developed wings but later in adulthood histolyzes its flight muscles. Importantly both flightless morphs have substantially increased reproductive output relative to the flight-capable morph. Much is known about the physiological and biochemical differences between the morphs with respect to adaptations …

Red Cloud's War And The Indian Victory Over The United States, Albert Winkler

Faculty Publications

Following the American Civil War, the United States fought a major war against the Sioux, Cheyenne, and Arapaho Indians known as Red Cloud's War, which lasted from 1866 to 1868. The conflict is noteworthy for its many raids, for its three significant battles, and because it was a costly American defeat and an important Indian victory. A prominent leader of the Native Americans was the great war chief, Red Cloud, who engineered much of their success. The conflict included several important and bloody engagements including the Hayfield and the Wagon Box Battles in 1867, and the highly significant Fetterman Massacre …

Plant Mediated Effects Of Earthworms On Aphid Dynamics, Nawzad Kadir

School of Biological and Marine Sciences Theses

The individual and combined effects of the endogeic and epigeic groups of earthworms on the growth of Chinese cabbage (Brassica rapa), and on the subsequent growth and development of the generalist sap-sucking herbivore Myzus persicae were determined in separate pot experiments. Many previous studies have investigated the relationship between soil biodiversity and aboveground plants, but few researches have considered the indirect interaction between soil biota and above-ground aphids. In this study the individual effects of Aporrectodea rosea and Allolobophora chlorotica and the combined effects of A. rosea and A. chlorotica, Aporrectodea caliginosa and Satchellius mammalis, A. chlorotica and S. mammalis, …

Spatial Distribution Of Soil Insects In Grassland, Karzan D.Ahmed

School of Biological and Marine Sciences Theses

Recently, there has been interest in the study of soil biodiversity and its functional role in agricultural grassland due to the need to develop management strategies for soil biota to improve ecosystem self-regulation. In the UK, grasslands provide a habitat for several subterranean insect taxa some of which are pests - leatherjackets (larvae of Tipulidae: Diptera) and wireworms (larvae of Elateridae:Coleoptera). To provide an appropriate method of pest management, a systematic sampling of agricultural grassland over different sampling scales is crucial in order to understand their population distribution and distribution patterns. The spatial distribution and distribution patterns of soil insects …

Antibacterial Activity Of Organic Acids And An Aqueous Lime-Peel Extract Against Selected Foodborne Pathogens, Haider Naji Kazim Al-Khanaq

School of Biological and Marine Sciences Theses

Food of animal origin contaminated with food-borne pathogens still concerns the public and food experts due to its harm toward public health. Using organic acids is one of the most important interventions for controlling the microbiological safety and quality of food and has been widely used. An increase of bacterial acid resistant species gave the motivation to find an alternative way to control foodborne pathogens in meat. Limited experimental studies have investigated the antibacterial activity of organic acids and an aqueous lime-peel extract combination on chicken meat against foodborne pathogens. The inhibitory effects of citric, propionic, acetic and lactic acid …

The Role Of Social Marketing In Salt Reduction, Michael Barry

Theses

More people die from cardiovascular disease than any other cause in Ireland (Department of Health, 2013). A direct correlation exists between high salt intake and high blood pressure and ensuing cardiovascular diseases (He and MacGregor, 2010). This thesis focuses on the use of social marketing to educate people on the dangers of high salt intake with the eventual aim of making recommendations to aid in the reduction of high blood pressure. In-depth interviews were conducted with twelve leading personnel from salt reduction and social marketing fields. All interviewees reached similar conclusions suggesting that salt reduction as a health issue needs …

Electronic Theses and Dissertations

The objective of this study was to investigate the effect of substituting soybean meal products with yeast-derived microbial protein [(YMP) DEMP; Alltech Inc., Nicholasville, KY] in diets containing two forage concentrations. Sixteen Holstein cows (4 primiparous and 12 multiparous) were randomly assigned to a replicated 4 × 4 Latin square in a 2 × 2 factorial arrangement of treatments. Diets contained low (LF; 45% of diet DM) or high forage (HF; 65% of diet DM) and YMP at 0 (NYMP) or 2.25% (WYMP) of the diet. The forage mix consisted of 67% corn silage and 33% alfalfa hay (DM basis). …

The Effects Of Maternal Energy Restriction During Mid-Gestation On Growth Performance, Immune Function, And Gene Expression In The Resultant Beef Offspring, Anna Rose Taylor

Electronic Theses and Dissertations

Fetal or developmental programming evaluates the effects of maternal alterations on the developing fetus and the potential consequences later in life. To understand the effects of mid-gestation energy restriction on beef cows and their calves the objectives of this dissertation were to determine the effects of dietary energy restriction on measurements associated with cow energy status, and the effects on growth performance, the humoral immune response, and subcutaneous adipose tissue gene expression in the resultant beef offspring. Pregnant beef cows were allotted into 2 treatment groups during mid-gestation: 1) fed at maintenance (Positive Energy Status (PES)); or 2) fed just …

Determining Impacts Of Mountain Lions On Bighorn Sheep And Other Prey Sources In The Black Hills, Joshua B. Smith

Electronic Theses and Dissertations

From 2009 to 2013, we assessed cougar (Puma concolor) feeding habits and bighorn sheep (Ovis canadensis) population dynamics in the Black Hills, South Dakota. We used Global Positioning System (GPS) telemetry to locate 1,506 cougar feeding events and found deer (Odocoileus spp.; 83%), primarily white-tailed deer (O. virginianus), dominated cougar diets. Overall ungulate kill rate averaged 0.79 ungulates/week (range = 0.13–1.75 ungulates/week), and was significantly higher (P < 0.001) in summer (xˉ = 0.92; SE = 0.06) than in winter (xˉ = 0.62; SE = 0.06). In contrast, biomass consumed was significantly higher (P = 0.033) in winter (xˉ = 8.23 kg/day; SE = 0.96) than in summer (xˉ = 5.45 kg/day; SE = 0.43), primarily as a result of increased scavenging (winter = 0.21 events/week; summer = 0.08 events/week), which represents the highest documented rate for cougar populations studied. We also documented a relatively high rate of chronic wasting disease- (CWD) infected elk in 2 cougar (1 male; 1 female) diets (64%; 95% CI = 50.3–78.3%) and speculate that CWD infection likely increased elk predation risk. Annual lamb survival was 0.02 (SE = 0.01) with pneumonia (36%) and predation (30%) the leading causes of mortality. We found pneumonia and predation were temporally heterogeneous with lambs most susceptible to predation during the first 2–3 weeks of life, while the greatest risk from pneumonia occurred from weeks 4–8. Annual ewe survival was 0.81 (SE = 0.04) with pneumonia (19%) and predation (19%) the leading causes of documented mortality; 48% were unknown. Additionally, we used vaginal implant transmitters (VITs) to assess capture efficiency and document parturition and neonate lamb bed site selection for bighorn sheep. We found successful VITs increased capture efficiency (95%) over unsuccessfully-vitted ewes (81%) and ewes not equipped with VITs (70%). Bighorn ewes selected for rugged terrain at both macro- and microhabitat scales, while at the macrohabitat scale ewes selected for areas that were close to perennial streams on south and west facing slopes and against anthropogenic disturbance. At the microhabitat scale, neonate lambs tended to select for greater cover and against north facing slopes.

Osteoarthritis And Articular Cartilage: Biomechanics And Novel Treatment Paradigms, Ray Marks

Publications and Research

Background: Osteoarthritis is a widespread highly painful disabling age-related disease with no known cure. Although novel strategies for ameliorating osteoarthritic damage abound, it is likely that none will be successful over time if the entire spectrum of the disease and the effects of joint biomechanics on joint tissues are not carefully considered.

Objectives: 1) To detail the structure of healthy articular cartilage, the key tissue affected by osteoarthritis. 2) To detail what aspects of cartilage damage best characterize osteoarthritis. 3) To consider the role of biomechanical factors in developing solutions to treat osteoarthritic joint damage. Methods: Literature sources from 1980 …

Pro-And-Anti Immigration Activities In Iowa's 4th Congressional District: A Community Capitals Framework Perspective, Anne Junod

Electronic Theses and Dissertations

The foreign-born immigrant population in Iowa is increasing. Across Iowa’s 4th Congressional District, communities that have never had statistically significant populations of non-Anglos have in recent decades experienced dramatic influxes of predominantly Latino immigrants. Today, Latinos comprise upwards of 25 percent of the population of some counties and well over 35 percent of the population of many towns. At the same time, many other communities in Iowa’s 4th Congressional District remain almost exclusively white. How are communities responding? This research centers on the statements and activities of individual and group actors representing various market, state, and civil society sectors, examining …

Antique Quarries Of Marmor Troadense (Nw Turkey): Insights From Field Mapping And Absolute Dating, Enver Vural Yavuz

Turkish Journal of Earth Sciences

In this study, we present new field and chronological data from 2 antique quarries of marmor troadense (Kestanbol quartz-monzonite) in northwestern Turkey. Marmor troadense has been mined and the building stones have been exported all over the Mediterranean region since approximately 2500 years ago. Analysis of 11 samples from the quarried bedrock for cosmogenic ^{10}Be showed that the landscape is so old that the inheritance obscured the absolute dating of the operation periods. Nonetheless, ^{14}C analysis of 4 charcoal samples from the sediments covering the ruins of Alexandria Troas indicated that these quarries stopped operating no later than 395 AD. …

Bicoelia Corticifera, A New Inozoid Sponge From The Upper Triassic (Norian) Reef Boulders Of The Central Taurids (Southern Turkey), Baba Senowbari-Daryan, Michael Link

Turkish Journal of Earth Sciences

Upper Triassic Norian reef boulders, exposed in a locality in the Central Taurids, southern Turkey, yielded a high number of hypercalcified sponges, including Sphinctozoans, Inozoans, Spongiomorphids, and Chaetetids. The reef boulders are exposed near the fountain Tavuk Çeşme, located at the road leading from the town of Aksu to Yenişarbademli. Geologically this locality belongs to the Anamas Akseki Autochthon. In this paper a new inozoan sponge, Bicoelia corticifera nov. sp., is described from Tavuk Çeşme. It is a cylindrical and unbranched sponge, found in several thin sections. The sponge is characterized by 2 axial spongocoels, and the sponge wall is …

Lost In The Shuffle: How Health And Disability Laws Hurt Disordered Gamblers, Stacey A. Tovino

Faculty Articles

Gambling disorder is not a legally sympathetic health condition. Health insurance policies and plans have long excluded treatment for gambling disorder from health insurance coverage. Individuals with gambling disorder who seek disability income insurance benefits from public and private disability income insurers also tend not to be successful in their claims. In addition federal and state antidiscrimination laws currently exclude individuals with gambling disorder from disability discrimination protections. This Article is the first law review article to challenge the legal treatment of individuals with gambling disorder by showing how health insurance and antidiscrimination laws hurt problem gamblers. Using neuroscience, economics, …

The End Of Indeterminacy In Affirmative Action, Carla Pratt

Faculty Articles

After the Supreme Court's decision in Fisher v. UT Austin, the stage has been set for judges to demand more specificity in the articulation of the protected diversity interest. Gone are the days when institutions of higher education could rely on the abstract concept of diversity to support efforts to enroll a diverse student body. Now higher education institutions will need to give serious thought to how they define the sought after diversity interest and how racial diversity improves educational outcomes and enhances the education that is delivered.
