The Design, Construction, And Testing Of Nucleic Acid Vaccines Against Salmonella Enterica Subspecies Enterica Serovar Javiana, Alexis A. Nguyen

LSU Master's Theses

Salmonella spp. is a Gram-negative bacterium that has the ability to replicate within a variety of hosts, or within the environment, including water, soil, and vegetation. These characteristics, coupled with the zoonotic nature of non-typhoidal Salmonella, pose a significant public health concern. Salmonella is the leading cause of foodborne illnesses worldwide, and in the United States alone, the economic impact due to non-typhoidal Salmonella illnesses in 2013 was estimated to be $3.7 billion, the majority of which were due to mortalities. In a time of rising antibiotic resistance, antibiotics are no longer considered the most effective treatment for …

Modeling Pelagic Feeding In The Gulf Of Mexico With Implications For Ecosystem-Based Fisheries Management, Rebecca L. Scott

USF Tampa Graduate Theses and Dissertations

The focus of this dissertation was simulating trophic dynamics in the pelagic Gulf of Mexico (GOM) with an emphasis on ecosystem-based fishery management (EBFM) strategies for large pelagic species. Fisheries management in the United States largely utilizes single-species assessments, although managers are increasingly interested in EBFM approaches to better account for ecosystem effects on stocks such as predator/prey dynamics. Production in the surface layer of the pelagic zone is variable with environmental conditions and prey is often concentrated in patches by hydrodynamic features. Production is also transported vertically via diel vertical migration, during which deep-sea species provide potentially key forage …

Effects Of Maternal Infant-Directed Sensory Cues On Early Weaned Piglet Behavior, Mattie Still

Animal Science Undergraduate Honors Theses

In the commercial pig production industry, weaning is a stressful time. Stress is related to loss in production due to increased incidence of illness, increased aggression, and reduced rate of gain, which results in economic losses for the producer. The purpose of this continuous behavior study was to explore the effects of provisional own-mother olfactory and auditory stimuli on early weaned piglet behavior and growth. During days 7-14 postpartum, the grunting of 12 individual sows was recorded while their piglets nursed. The audio files were put into a single loop with grunting occurring for 20 minutes followed by 60 minutes …

A Comparison Of Shaping And Imitation For Reducing A Dog’S Problem Behavior, Carlee Weir, Robbie Hanson

Theses

Over one million dogs have entered shelters in 2024 alone with approximately 31% of those dogs being relinquished by their owners (Shelter Animal Count, 2024). Further, non-aggressive behavioral issues are often cited as a primary cause for owner relinquishment (Best Friends Network Partners, 2018; Howard & DiGennaro Reed, 2014). Previous research has shown the effectiveness of training methods based on positive reinforcement to reduce problematic behavior with dogs and to increase desirable behavior, such as shaping and clicker training, and there has been a growing interest in the use of imitation during training. Fugazza and Miklosi (2015) compared a shaping …

Comparing The Effectiveness Of Different Forms Of Vitamin E Supplementation (Liquid Vs. Powder) On Serum Alpha-Tocopherol Concentrations In Developing Horses, Emilia Fong-Gallagher

Honors Scholar Theses

Vitamin E is an essential antioxidant in equines that has a significant role in the nutritional requirements of horses to keep bodily systems functioning at optimal levels. Vitamin E deficiency is often associated with serious incurable neuromuscular diseases such as equine motor neuron disease and equine protozoal myeloencephalitis. Many horses stabled in urban areas are often deficient due to the lack of adequate grazing time as their natural source of vitamin E is from grass, and therefore should receive supplementation. This study evaluated the effectiveness of different forms of Elevate vitamin E supplement on the serum alpha-tocopherol concentrations in fourteen …

Tri-Colored Bat Habitat Use And Selection In Northwestern South Carolina, Eduardo Rosales

All Theses

North American bat populations continue to be decimated by many factors, with the largest contributor being white-nose syndrome (WNS). In recent years researchers have noted the importance of fat reserves pre- and post-hibernation (fall and spring) and how they may influence WNS survival and recovery respectively. Tri-colored bats (Perimyotis subflavus) are one of the four species most impacted by WNS but have received the least research. Further, thus far all research on tri-colored bat resource selection has been gathered during summer and winter, highlighting the need for habitat selection studies during the fall and spring pre- and post-hibernation …

The Spatial And Behavioral Ecology Of The Eastern Box Turtle In A Suburban Landscape, Emma Rogers

All Theses

Urbanization poses a significant threat to wildlife through fragmentation, degradation, and loss of habitats. Species response to urban development is variable, from species that thrive in urban areas to those that avoid them. Eastern box turtles (Terrapene carolina carolina) can live and reproduce in urban areas; however, reports of population decline throughout the species’ range have raised concerns. The objective of this study was to compare home range size and composition, as well as the microhabitat selection of the Eastern box turtle across a developmental gradient in Clemson, SC. We tracked 14 individuals in habitats along a developmental …

Evolution Of The Human Eye: As Compared To Other Vertebrates, Madison Queener

Honors Projects

There are three different types of eyes, the simple eye, the compound eye, and the camera eye (Cambridge Dictionary) (Myer-Rochow, 2014) (UCL, 2020). The retina of the eye has evolved and adapted to fit the lifestyles of the respective organisms. Because of this part of the eye, organisms are able to see different colors and use light to define the world using photoreceptors. Photoreceptors are rod cells, which are light sensitive and process light, and cone cells, which perceive the different color wavelengths, that pass visual information to the brain (Kazilek, 2010). About 5% of the photoreceptors in the retinas …

A Comparison Of The Prevalence Of Salmonella, Specifically S. Enteritidis, In Captive Born Versus Wild Caught Reptiles, Jessica Thomas, Carrie M. Doyle

Undergraduate Theses

Salmonella contamination and transmission is a concern in public health in the United States and around the world. It is usually transmitted to humans through contaminated poultry products, but it has also been known to be transmitted through contact with reptiles. Because reptiles are becoming more popular as pets and are known carriers for Salmonella, studies have been done to test how prevalent Salmonella is in reptiles. This study focused on testing the feces of twenty-two reptiles for Salmonella, in general, and a specific serotype of Salmonella, S. Enteritidis. This study also compared the positivity rate of reptiles born …

Grazing On The Arizona Strip: Catchment History And Repair, Melanie Heaton

All Current Publications

Water, not forage, is the limiting factor for wildlife and livestock grazing the Arizona Strip, a nearly 3-million-acre piece of land located north of the Grand Canyon and south of the Utah border. Since springs and groundwater are rare or absent, harvesting of natural precipitation is the main source of water for animals. Catchment systems, which capture precipitation on a sloped rubber apron and contain it in a large tank or lined pond, are used by government agencies and grazing permittees to efficiently provide water for wildlife and livestock. As catchments reach the end of their useful lives, tank replacement …

Hilling As A Management Tactic And Tool For Understanding Soybean Gall Midge (Resseliella Maxima Gagné), Pragya Gupta

Department of Entomology: Dissertations, Theses, and Student Research

Soybean gall midge (Resseliella maxima Gagné, SGM) emerged as a new species in the United States Midwest in 2019, causing injury to soybean (Glycine max L.) Infestation of R. maxima starts with females laying eggs in the fissures or cracks that develop at the base of soybean during the V2-V3 growth stage. The emerged larvae feed on the stem internally, leading to wilting and death of the plants. With knowledge gaps in biology and behavior, management strategies for this pest are challenging. Hilling is a cultural practice causing soil to cover the base of stems and is …

Vigilance And Foraging Behaviors Of Two Sciurid Species Between College Campuses And Urban Environments, Patrick Geyer, Zoe Buffington, Lorelei E. Patrick

SACAD: Scholarly Activities

A comparison between the extent that sciurid specimens display vigilance and foraging behaviors on college campuses against specimens within urban environments. Observations of fox squirrels and western gray squirrels were taken from the Squirrel-Net behavioral database used for this project. We found there was a significant difference between the percent vigilance behaviors and foraging behaviors on college campuses compared to urban environments. This suggests that squirrels residing on college campuses are more desensitized to pedestrian activity and foot traffic compared to squirrels that inhabit urban areas.
