Managing Dietary Nonstructural Carbohydrates In Insulin Dysregulated Horses: Pasture, Long-Stem Forage, And Restrictive Grazing Strategies, Morgan J. Askins

Theses and Dissertations--Veterinary Science

Insulin dysregulation (ID) is a complex endocrine disorder, impacting a large percentage of the equine population. ID is the defining characteristic of equine metabolic syndrome (EMS). Within the various classifications of EMS horses, the commonality is ID and their higher risk of laminitis. To mitigate insulin response and laminitis risk in ID horses, current management focuses on restricting pasture exposure and feeding low nonstructural carbohydrate (NSC) rations. Minimal studies have evaluated how ID horses respond to pasture of various NSC, long-stem forages, and restrictive grazing strategies. Providing horse owners and managers with improved nutritional management recommendations for ID horses with …

Between The Rails: Experiential Education And Its Impact On Compliance And Consistency In Racetrack Surface Management, Heather Mackenzie

Theses and Dissertations--Community & Leadership Development

Recent regulatory requirements within the Thoroughbred racing industry have increased expectations for consistent collection and reporting of racetrack surface data. Despite clear standards, implementation in daily operations remains inconsistent, highlighting a gap between regulation, knowledge, and practice. This study examined the impact of an experiential education curriculum on racetrack personnel’s self-efficacy and reporting consistency.

Using a quantitative design, data were collected through pre- and post-surveys measuring self-efficacy and records of the number of days surface data were entered. Descriptive statistics, paired-samples t-tests, and effect size analyses were used. Results showed a statistically significant increase in self-efficacy (p < .001) with large effect sizes, indicating meaningful gains in confidence and comfortability. Reporting consistency did not show a statistically significant change (p = .885).

Overall, experiential education …

Systematics Of Disk-Winged Bats (Thyroptera), Courtney L. Klumpp

Capstone Showcase

This thesis investigates the evolutionary relationships among disk-winged bats in the genus Thyroptera, a small group of Neotropical bats known for the adhesive suction disks on their wings and feet that allow them to roost inside tightly rolled leaves. The distinctive morphology and behavior of these bats have not been extensively documented, and their phylogenetic relationships remain only partially resolved. The goal of this research is to better understand how these species are related to one another and to determine whether the five recognized species of Thyroptera form a single monophyletic group. To address this question, morphological and genetic …

Genomic Signatures Of Decline And Recovery In An Endangered Bat, Myotis Grisescens, Marxe Altman-Orbach

Graduate Theses/Dissertations

Tremendous population declines may result in the loss of genetic diversity, which can, in turn, lead to reduced adaptive potential, overexpression of deleterious phenotypes, and further population declines. In this way, genetic drift from a severe demographic decline may ultimately lead to an extinction vortex. However, populations that avoid the loss of genetic diversity may remain viable, despite demographic crashes. Therefore, understanding genetic diversity is vital for assessing the conservation status of species that have undergone declines, and can even reflect the effectiveness of management actions. I investigated signatures of genetic bottlenecks in the gray bat (Myotis grisescens), …

Dietary Ecology Of Waterfowl Nest Predators In The Prairie Pothole Region: Evaluating Resource Use From Species To Individual Using Stable Isotope Analysis, Grace Barthelmess

EWU Masters Thesis Collection

Nest predation is a primary factor influencing waterfowl productivity in the Prairie Pothole Region (PPR) of North America. Although this system is intensely managed and studied, research has largely focused on how predators affect waterfowl populations, with comparatively little attention to how predators actually rely on waterfowl as a resource. Understanding predator feeding ecology is therefore critical for informing effective management strategies and interpreting the complexity of predator-prey interactions on this landscape. My objective overall was to elucidate the feeding ecology of nine focal predator species commonly associated with waterfowl nest predation in the Aspen Parkland Ecoregion of the PPR: …

The Effects Of Environmental Complexity On Brain Development And Personality Expression In Western Hognose Snakes, Gokulan Nagabaskaran

Theses and Dissertations (Comprehensive)

There is growing interest in snake cognition, personality, and welfare as more snakes are kept as pets, yet little research has been conducted. The effects of enrichment and environmental factors have been well documented in other taxa, and recent evidence suggests that snakes may benefit in similar ways. This dissertation investigated the impact of environmental and social enrichment on personality expression, personality stability, and brain development. Western hognose snakes (Heterodon nasicus) were used as the model species, as they are a popular choice in the pet trade. This allows the research to be readily translatable to husbandry practices of many …

A total of 109 Landrace × Yorkshire sows (parity 1–7) were assigned to either a control group (n = 61) or a treatment group (n = 48) receiving Bacillus subtilis – 541 and Bacillus amyloliquefaciens – 516. Piglets in the treatment group also received the probiotics via creep feed from day 3 until weaning. Blood samples were collected within 12 h after farrowing to assess serum immunoglobulins (IgG, IgA, and IgM) and malondialdehyde (MDA) …

Measuring Welfare Of Wild Tarantulas During Field Surveys Using Heart Rate, Tim Angelo Artiaga Lopez, Becky Hansis-O'Neill, Aimee Dunlap Phd

Undergraduate Research Symposium

Tarantulas (Theraposidae) are predatory arachnids that can help control populations of herbivorous arthropods. We have been monitoring populations of the Missouri brown tarantula (Aphonopelma hentzi) in Missouri glades for three seasons and have questions about their welfare during these surveys. Unlike mammals, arthropods are not extensively researched and there are only a few known facts about measuring their welfare. Managing stress for wild animals during field surveys is important for reducing the potential negative impacts of research. In mammals, increased heart rate is positively correlated with negative stress and eustress. Using the same logic, we hypothesized that heart rate could …

White Nose Syndrome In Bats And Infant Mortality In Georgia, Rhys Medcalfe, Sean Medcalfe, Simon Medcalfe

Journal of the Georgia Public Health Association

Background: White nose syndrome (WNS) is a disease in bats caused by the fungus Pseudogymnoascus destructans that can result in bat mortality rates of over 90%. WNS was discovered in Georgia in 2012 in 3 counties but has continued to spread to 14 counties as of 2023, with P. destructans detected in a further seven. Biodiversity loss has been linked to human health outcomes including infant mortality. Understanding the link between WNS, biodiversity loss, and infant mortality in Georgia is important because Georgia ranks 42^nd out of the 50 states for infant mortality rate.

Impacts Of Nutrient Addition And Disturbance On Coastal Dune Arthropod Communities And Trophic Interactions, Kayla Beitzel

Graduate Theses and Dissertations (2019 - present)

Coastal dune ecosystems face ongoing threats from human-mediated disturbance and altered resource availability. Because these dunes provide critical habitat for many organisms, including shorebirds, beach mice, and arthropods, changes in disturbance regimes or resource availability can impact plant communities and higher trophic levels by altering plant richness and productivity, which in turn influence arthropod abundance and diversity. To examine how disturbance and nutrient addition affect arthropod communities, we established twenty 5×5 m plots on Dauphin Island, crossing mechanical disturbance with a 10 g m⁻² addition of nitrogen, phosphorus, and potassium, replicated across five experimental blocks. Arthropods were sampled using three …

Mhc Gene Analysis And Immune Variation In Lepidodactylus Lugubris (The Mourning Gecko), Helen T. Vu

2025 Fall Honors Capstones Projects - Archive

The major histocompatibility complex (MHC) plays a central role in vertebrate immune defense by enabling pathogen recognition and initiating adaptive immune responses. While MHC diversity has been extensively studied in sexually reproducing species, comparatively little is known about its evolution in asexual lineages. The parthenogenetic gecko Lepidodactylus lugubris provides a unique opportunity to investigate how clonality and hybrid origins influence immune gene diversity. By leveraging whole-genome data, this study overcomes the limitations of previous transcriptome-based analyses and provides a more comprehensive view of MHC diversity in a clonal vertebrate. As the first step towards understanding MHC evolution in parthenogenetic lizards, …

Black Soldier Fly (BSF) larvae offer a cost-effective, nutrient-rich alternative to synthetic fertilizers and conventional feed inputs such as soy, fishmeal, and maize bran in sub-Saharan Africa. In Malawi, where smallholder farmers grapple with declining soil fertility, high input prices, chronic food insecurity, and livestock nutritional challenges, BSF farming is emerging as a promising circular agricultural innovation. Despite its technical promise, the social, economic, and ecological realities of BSF adoption remain underexplored.This study investigates the early implementation of BSF farming in Malawi through the Sustainable Livelihoods Framework, focusing on farmer experiences, challenges, and the social and structural processes shaping uptake …

Polyphenols For The Mitigation Of Vascular Calcification; In Vitro And In Vivo Studies, Abdullah Altuhami

All Theses

Globally, cardiovascular diseases, in most cases associated with calcification, are the main cause of death. However, currently, the only effective cure is to undergo surgery to augment or receive a healthy donor heart, which could be very difficult due to the long waiting list and the associated risks. The possibility of body rejection of the foreign organs is attributed to immunoreaction or the risk of infection, since the donor must be on immunosuppressant drugs that lower the body's immunity and facilitate the body's acceptance of the new organ as one of its own. Taking that into consideration, using tissue-engineered vascular …

Maternal Hyperleptinemia Alters Placental Transcriptome And Progesterone Regulation Without Affecting Early Equine Fetal Growth, Lucinda L. Thorburn

LSU Master's Theses

While consequences of equine obesity are well defined, the extent to which persistent hyperleptinemia and accompanying leptin (Lep) resistance affect the fetal-maternal environment warrants further exploration. This study compared endocrine, fetal, placental, and uterine parameters during early pregnancy (through day 70) in mares with elevated leptin versus normal leptin (NL) concentrations. Fourteen mares were classified as either NL (n = 6; Lep 0.9 ± 0.3 ng/mL), moderate leptin (ML; n = 4; Lep 3.0 ± 0.3 ng/mL), or high leptin (HL; n = 4; Lep 5.8 ± 0.7 ng/mL) based on annual plasma leptin. Mares were artificially inseminated and induced …
