Population Ecology Of Rocky Mountain Elk In The Black Hills, South Dakota And Wyoming, Benjamin D. Simpson
Electronic Theses and Dissertations
We conducted a 2-year (2012–2013) study of survival and cause–specific mortality using individually marked adult cow and neonate elk (Cervus elaphus) occupying the southwestern region of the Black Hills. We used known-fate analysis in Program MARK for survival analysis of adult cows and calves. We estimated survival and cause-specific mortality of 49 adult female elk over the 2 years of the study. Annual adult cow survival was 0.85 (95% CI = 0.72–0.87). We documented 12 mortalities with harvest (58.3%) and predation (16.6%) accounting for the majority of known mortalities. We captured and fit 71 neonates < 10 days of age with expandable Very High Frequency (VHF) radiocollars during summer 2012 (n = 37) and 2013 (n = 34). Annual (12 month) survival of elk calves was 0.75 (95% CI = 0.61–0.84) while summer (20 weeks; 15 May–25 September) survival was 0.79 (95% CI = 0.68–0.88). Predation accounted for 87.5% of mortalities; remaining mortalities were from starvation (6.3%) and unknown (6. 3%) causes. We used Global Positioning System (GPS) collars to collect 167,707 locations to determine home range, movement ecology, and macroscale resource selection of 48 adult cow elk. We documented elk using a variety of migration strategies (obligate migrator, resident, conditional migrator, disperser); the majority of the population (58%) was migratory. Spring migration distance travelled ranged from 2.45 km – 74.44 km (n = 42); fall migration distances ranged from 6.41km – 153.95 km (n = 46). We used 99% Brownian Bridge Movement Models to create seasonal and overall home ranges of adult cow elk. Mean overall home range size for conditional migrators was 249.28 km2 (SE = 28.60, n = 7, range = 233.75), for obligate migrant elk it was 227.18 km2 (SE = 13.94, n = 29, range = 346.83), and for resident elk it was 175.65 km2 (SE = 22.75, n = 11, range = 216.04). We used discrete choice models to determine resource selection at the macro-habitat scale of collared adult elk using ArcMap 10.1 data. Adult cow elk selected for open grassland/herbaceous areas and early successional forest areas close to forested edges at higher elevations. Our study showed that elk populations have the ability to thrive within an ecosystem with healthy predator populations.

Visual Phallacies, John Howard Cummings
Electronic Theses and Dissertations
Roland Barthes wrote that only after removing all of the author's intentions and traces can a work of art truly be perceived by viewers fairly (Barthes). A viewer's perception of the world is influenced by his or her individual subjective history, which is the product of his or her own experiences. But as the author of ceramic work, my influence is ever-present. Clay records every push, pull, spank, squeeze, and poke. It fully records its physical history and as well as my actions upon it. This thesis exhibition asks the question: Can a viewer de-contextualize familiar-but-contentious subject matter and be …

The Biogeography And Diversity Of Termites In Southern Africa, Brianna Lind
The Biogeography And Diversity Of Termites In Southern Africa, Brianna Lind
Electronic Theses and Dissertations
Termites (Blattodea: Termitoidae) are socially complex insects that are morphologically diverse and live in colonies. They represent a highly specialized form of cockroach that organizes into castes (distinct social groups including workers, soldiers, queen, etc.) that have specific roles within the colony (Eggleton 2010). Globally more than 2,600 species of termites have been described in over 280 genera and, while termites can occur in most climatic zones warmer than tundra, their greatest abundance and ecological significance is in the tropics (Kambhampti and Eggleton 2000). Termites impact many processes, including nutrient cycling, water dynamics, and soil porosity; in African savannas it …

Studies Related To Microbially Induced Corrosion Of Stainless Steel 304 And 316, Somil Gupta
Electronic Theses and Dissertations
Pitting corrosion of stainless steel (SS) is observed in many different industries including the dairy industry. It is of concern, because it weakens the steel, and can cause cracking. Any replacement or repair of SS equipment is very costly and also causes delays in product manufacture. Microbial Induced Corrosion (MIC) is a possible accelerator of natural corrosion seen in galvanized steel pipes. Studies have shown a correlation between surface roughness and the ability of bacteria to colonize and form biofilms. Dairy industry utilizes higher food grade SS 304 and 316. However, even these relatively corrosion resistant stainless steel grades may …

Volunteer Glyphosate-Resistant Corn And Soybean Competition And Control, Jill Alms
Electronic Theses and Dissertations
The continuous use of glyphosate-resistant crops has resulted in volunteer crops with the same herbicide resistance as the cash crop and an increasing weed problem. Volunteer corn reduces soybean yields however; little research has examined corn yield loss due to volunteer corn or volunteer soybean competition. These studies investigated yield loss and control of volunteer soybean in corn, and volunteer corn in soybean and corn. Using several densities of competitive plants, the yield loss was fit to a hyperbolic equation that indicated incremental yield loss (I value) to be 29.9 for volunteer corn in soybeans, 5.6 for volunteer corn in …

Non-Invasive Drug Delivery To The Posterior Segment Of The Eye: Development Of Formulation Strategies And Evaluation Of Ocular Distribution And Pharmacological Activity, Goutham Reddy Adelli
Electronic Theses and Dissertations
Diseases of the posterior segment of the eye such as diabetic retinopathy, age related macular degeneration and glaucoma are the leading causes for blindness throughout the world. Topical eye drops is the most convenient formulation for daily application. The human eye, however, presents major physiological and dynamic barriers for the topically administered drug/molecule from reaching the retina. Similarly, the blood-retinal and blood-aqueous barriers restricts passage of drug from systemic circulation into the eye. Although intravitreal injections are the gold standards for the treatment of posterior segment ocular diseases, they are associated with pain, inflammation, endopthalmitis and infection. So there is …

Screening Of Natural Products For Their Effect On Kallikrein-Kinin System: Potential Implications In The Treatment Of Hereditary Angioedema, Hassan Abdu Madkhali
Electronic Theses and Dissertations
Plasma prekallikrein (PK) activation exerts both physiological and pathological effects within the cardiovascular system and central nervous system (CNS). Activated PK (kallikrein) controls cytokine release from human mononuclear cells and controls both the intrinsic blood coagulation and the alternative complement cascades. The uncontrolled activation of these cascades results in the development of pathological pain and angioedema. Increased plasma kallikrein levels are associated with hereditary angioedema (HAE) and myocardial infarction, whereby kallikrein amplifies the generation of activated factor XII (FXIIa) and bradykinin (BK) release from high molecular weight kininogen (HMWK). The primary objective of this study was to screen natural products …

Fetishizing Southern Brutality: An Intersectional Analysis Of Animalistic Dehumanization In Interracial Pornography, Shawna Faye Felkins
Electronic Theses and Dissertations
Pornography has been a widely debated issue within the feminist movement since the sex wars of the 1970’s. The conversation has shifted to a sex radical position within the third movement, seeking to be “sex positive” in representations of pornography as a potential site of empowerment. This work, however, seeks to complicate the idea that all depictions of sex are empowering by examining the popular genre of interracial pornography through the lens of the southern tropes that are often enacted within them: the jezebel, southern belle, and black brute. By using these historical tropes with the work of Judith Butler …
