Photo Identification On Interactions Between Tursiops Trucatus And Humans To Promote The Importance Of Sustainability, Julia Bronneberg

Undergraduate University Honors Capstones

The Mediterranean Sea is one of the most biodiverse regions, and especially around the Maltese islands, a popular tourist destination where people come to enjoy the beautiful weather and blue waters. Because bottlenose dolphins (Tursiops truncatus) are the most common species people see in coastal areas, they are the primary focus of this research. We care about these bottlenose dolphins because they cannot protect themselves if we are the ones accidentally causing them harm. This study starts from the belief that if we cannot protect the ocean and marine life, then we cannot protect ourselves. We use many resources that …

Life Histories Of Two Sgcn Procambarus Species In East Texas, Mckenzie A. Adkins

Biology Theses

Within freshwater systems, crayfish play notable roles by shaping habitats and linking food web levels. Yet even with such influence, knowledge about numerous species is incomplete, which hinders protection strategies. Found only in the Neches River basin in eastern Texas, Procambarus nechesae and Procambarus nigrocinctus have different conservation statuses, mainly because data on their life history remains sparse. These two species are not closely related and are analyzed independently in this study. Research into traits tied to survival and environmental preferences was carried out so that informed decisions on conservation efforts can be made for these species. The goal of …

Bio 340 Final Project: Artificial Reef Effects On Fishing Productivity, Griffin Gouck

Biology Student Scholarship

Griffin Gouck - Environmental Biology '26

A slew of artificial reefs can be seen dotting the Gulf of America. Some result from catastrophic shipwrecks and others from construction dumping; however, all provide an opportunity for the development of marine ecosystems. The question of how artificial reefs effect local fish populations is an expansive concept extremely hard to simplify down to a basic relationship. The development of reefs is a delicate process taking place over many years of growth. Previous studies utilized a combination of resources like theoretical models, field data and comparisons to natural reefs to study how these artificial …

Brachial Macroparasite Loads In Estuarine Young-Of-Year Striped Mullet (Mugil Cephalus), Triston Rice

Honors Theses

Climate change is a growing threat to marine habitats globally. One ecological impact that warming water temperatures poses is the increased metabolic rate of many parasite species. Their promoted reproductive and feeding rates could pose a threat to the stability of many host populations. Parasites of the gills, or brachial parasites, are especially concerning to fish populations globally. As parasitism is not limited to a specific taxon and comprises a large diversity of ecomorphs and behaviors, geographically distinct areas may be differentially affected by the changing prevalence of parasites. This study aimed to survey current brachial parasite abundance and prevalence …

Community Composition Of Antibiotic-Resistant Bacteria On The Mississippi Gulf Coast, Marisa Martin, Colin Jackson

Honors Theses

The Mississippi Gulf Coast is an important resource for transportation, economic development, and recreation. Given its economic and cultural importance, it is crucial to maintain clean and safe conditions along the coast for public health, but other than routine beach monitoring, few studies have examined microbial contamination of coastal waters in this region. This study aimed to determine the quantity, composition, and distribution of bacteria resistant to six different antibiotics (Vancomycin, Kanamycin, Tetracycline, Ciprofloxacin, Erythromycin, or Amoxicillin) in seawater at seven public beaches along the Mississippi Gulf Coast. No bacteria resistant to Ciprofloxacin were detected, and bacteria resistant to Kanamycin …

Optimization Of Refolding, Purification, And Analytical Characterization Of Proinsulin(F25d) Soluble Antigen Array Immunotherapy, Abigail Richardson

McKelvey School of Engineering Graduate Student Theses & Dissertations

Type 1 Diabetes (T1D) is characterized by autoreactive immune responses to insulin and its precursor, proinsulin. Soluble antigen arrays (SAgAs) displaying the metabolically inactive proinsulin variant, proinsulin(F25D), represent a promising antigen‑specific immunotherapy candidate for T1D. However, the production of these platforms is hindered by substantial practical challenges, including protein aggregation, inefficient refolding, and the lack of sensitive analytical tools to verify quality and dosage. This work establishes an integrated, scalable pipeline for the purification, conjugation, and quantification of a proinsulin(F25D) SAgA. First, we optimized the refolding of recombinant methionine-proinsulin(F25D) (M-PI(F25D)) from inclusion bodies using controlled buffer systems and created a …

Acquisition Behavior Response: Investigating The Ability Of Leptoglossus Phyllopus To Choose Between A “Good” Versus “Sub-Optimal” Strain Of Caballeronia, Irene L. Pham

2026 Spring Honors Capstones Projects

Leptoglossus phyllopus is a polyphagous pest that primarily feasts on citrus, tomatoes, and legumes. They must form a mutualistic symbiosis with Caballeronia every generation by ingesting the bacterium from their environment. However, not all species of Caballeronia confer the same fitness on the L. phyllopus host, raising the question of whether L. phyllopus possesses a partner choice mechanism that would allow it to distinguish between a good (GAOX1) and a suboptimal (Lep1P3) symbiosis partner. This was examined by conducting a choice experiment in which the two symbionts (GAOX1 vs. Lep1P3) were placed in a plastic box, and the bug’s roaming …

The Meaning Of Physical Activity In The Context Of Health Sciences: A Concept Analysis, Martín G. Farinola

International Journal of Physical Activity and Health

Physical activity has been defined in numerous ways. Thus, this study aimed to conduct a concept analysis of the existing physical activity definitions in the health sciences literature to evaluate its conceptual precision and assess the need for a revised or novel concept better suited for this domain. The concept analysis was accomplished using tools derived from philosophical semantics. The analysis identified six definitions that explicitly state what physical activity is with sufficient clarity to allow for conceptual examination. The findings indicated that these definitions frequently merge the concept of physical activity with its contextual attributes. To address these semantic …

Teaching Exercise: A Survey On Educational Aids And Self-Efficacy, Joshua I. Eaton, Lucas Morgan, Matthew Hermes

Honors College Theses

HEPs are an important part of therapeutic treatment because they allow for greater exercise stimulus than can be achieved from supervised exercise alone. 94.7% of physical therapists reported prescribing HEPs to their patients. However, patient adherence to these plans can be as low as 35%. Lack of HEP adherence likely leads to sub-optimal clinical outcomes in physical therapy patients. Self-efficacy is improved in patients by supplementing HEPs with instructional aids, especially in the form of videos instead of pictures or descriptions, because they act as a form of vicarious experience. It is possible that improving self-efficacy through vicarious experience could …

Neural Mechanisms Underlying Jung’S Active Imagination: A Review And Hypothesis, Charles R. Fox

Journal of Conscious Evolution

Active imagination is a key technique of Jungian analysis. Despite its centrality, and its potential importance beyond Jungian psychology to the area of systems neuroscience, psychology, and consciousness studies, there are no known neurological mechanisms underlying this psychological phenomenon. There is a history of using the types of mental imagery used in active imagination to explore consciousness. The development and use of active imagination is briefly reviewed, and a case is developed that the neurology underlying active imagination would be fruitfully explored by considering it a special case of mystical experience. Active imagination primarily uses the right hemisphere processing of …

Consumerism In The Digital Age: Environmental And Cultural Consequences, Danielle Andrea Montoya

Student Theses 2015-Present

Overconsumption has emerged as a significant environmental problem, characterized by persistent patterns of buying, using, and discarding goods at rates that exceed ecological limits. In the digital age, these patterns of consumption are reinforced by economic systems, technological advancements, and cultural norms that make constant consumption feel normal and convenient. While consumption is necessary for everyday life, consumption beyond basic needs contributes to increased waste, resource depletion, pollution, and climate change. Overconsumption is embedded in daily habits such as online shopping, food consumption, and frequent product replacement. Therefore, understanding and addressing overconsumption is crucial for achieving environmental sustainability and social …

Status Of The Potentially Invasive Australian Redclaw Crayfish (Cherax Quadricarinatus), Margaret (Addie) Munn

Biology Theses

The introduction of invasive species, including crayfish, is common through aquaculture and aquarium trade pathways and is an important factor causing the decline and/or extinction of native species. Invasive species cause billions of dollars in damages annually and threaten almost half of the native species in the United States. Australian Redclaw Crayfish (Redclaws) are a species of large individuals that originated in Australia and New Guinea and have been introduced specifically for aquaculture and the aquarium trade. Redclaws are known to thrive in tropical and subtropical locations. They can tolerate high temperatures and low oxygen and are generalist omnivores that …

Utahns Prefer State Management Of Public Lands, Casey Trout, Michaelann Nelson, Jessica D. Ulrich-Schad

Utah People and Environment Poll (UPEP)

In August 2024 the Utah Attorney General’s Office filed a Bill of Complaint challenging the federal government’s ownership of 18.5 million acres of unappropriated land within the state’s borders (1). The state intends the lawsuit to pave the way for eventual transfer of the land to state ownership (2). The Legislature allocated roughly $20 million to the lawsuit as well as a marketing campaign to increase public support for efforts to transfer public lands out of federal ownership. Of that, over $500,000 was spent on attorney’s fees related to the case and over $2.6 million was allocated to a marketing …

Assessing The Conservation Needs Of Native Texas Crayfish Species Through Distribution Analysis And Species Distribution Modeling, Elizabeth J. Croft

Biology Theses

Crayfish have essential roles in ecosystems because they are ecosystem engineers and keystone species. However, crayfish species are threatened by degradation and loss of habitats, introduction of invasive species, and high levels of endemism. Texas provides no legal protections for crayfish, despite its large number of species and endemics in the state. The overall goal of this study is to clarify the distributions of native Texas crayfish species using literature records, citizens science, and field sampling data, and highlight species in need of more conservation research. Occurrence records from all collected data were combined to visualize the distributions of species …

Sequence Determinants Of Rna G-Quadruplex Unfolding By Arg-Rich Regions, Naiduwadura Ivon Upekala De Silva, Puspa Kunwar, Md Ibnul Rifat Rahman, Joanna Koryo Kwao, Nathan Lehman, Zihan Zhang, Trenton Paul, Claire Cheng, Nicholas Truex, Hui-Ting Lee, Jun Zhang

Faculty Publications

RNA sequences with the potential to form G-quadruplexes (rGQs) are widespread but largely unfolded in cells by unknown mechanisms. rGQ folding status is a critical regulator of RNA splicing and translation. We show that rGQs can be unfolded by SR proteins, SR-related proteins, and other Arg-rich proteins, including SRSF1, SRSF3, SRSF9, U1-70K, and U2AF1. The length and composition of Arg-rich regions are key determinants of this activity: Arg residues are the primary drivers, while acidic residues attenuate the unfolding activity. To unfold ARPC2 rGQ, at least 13 Arg residues are required. Our findings identify Arg-rich proteins as previously unrecognized, helicase-independent …

Clinical And Demographic Characteristics Of Hospitalized Patients With Xylazine-Related Wounds, Elizabeth Novick, Nikhil Seval, Dagan Coppock, Mollie Tucker, Daniel Taupin, John Zurlo, Carolyn Kramer

Department of Medicine Faculty Papers

OBJECTIVES: Little is known about the demographic and clinical features of patients with xylazine-related wounds. We sought to characterize hospitalized patients with substance use disorder (SUD) and xylazine-related wounds seen for infectious diseases consultation.

METHODS: We retrospectively reviewed the medical records of 193 patients diagnosed with SUD at 3 Philadelphia hospitals between October 2023 and January 2024. Patients were identified as either being diagnosed with (n=73) or without (n=120) xylazine-related wounds. We compared the demographic and clinical features between the 2 groups.

RESULTS: Patients diagnosed with wounds were younger ( P < 0.001), more likely to be White or Hispanic and less likely to be Black/AA ( P < 0.001), more likely to have tested positive for fentanyl ( P < 0.001), amphetamines ( P < 0.001), and cocaine ( P 0.001), more likely to acknowledge injection ( P < 0.001), and more likely to leave the hospital by patient-directed discharge (PDD) ( P < 0.001). Most patients had multiple wounds (75%), and more than half (53%) had at least one wound greater than 10 cm at its widest dimension. Although most patients diagnosed with wounds received antibiotics, many did not have symptoms or signs of infection.

CONCLUSIONS: Xylazine-related wounds are highly associated with illicitly manufactured …

Aggregation And Collation Of Texas Crayfish Museum Specimens To Determine Their Current Conservation Statuses, Adrian Alvarez

Biology Theses

Crayfish account for over half of the macroinvertebrate biomass in many ecosystems and serve as crucial bioindicators because of their behavioral and physiological adaptability to environmental changes. Despite being home to approximately 52 native crayfish species, Texas currently lacks protective regulations. This gap is primarily because of insufficient information regarding their distribution and occurrences within the state, including their statuses as Species of Greatest Conservation Need (SGCN). This study focuses on compiling and comparing crayfish museum records with current iNaturalist field survey data across Texas to address these knowledge gaps and recommend updates to SGCN statuses. Five species not currently …

Hormonal, Cytokinetic, And Skeletal Response To A Single Weighted Vest Exercise Treatment: A Pilot Study To Determine Weighted Vest “Rucking” Treatment For Osteoporosis In Post-Menopausal Women, Eleanor Pell

Master's Theses

Osteoporosis is characterized by a deteriorating of bone tissue leading to brittleness and increased fracture risk that affects both men and women as they age. Postmenopausal women are of particular interest due to high risk of declining bone density, a characteristic of this population. Treatments for osteoporosis range from menopause hormone therapy, bisphosphonates, biologics, nutritional changes, and exercise. Load bearing exercise interventions have shown effectiveness for stimulating bone growth, but many factors such as lack of access, motivation, self-confidence or knowledge, prevent long term compliance. “Weighted vest rucking” refers to a variation of rucking, which is a form of exercise …

Companion Parrot Vocal Learning And Reproduction Of Human Speech Sounds, Karla Vilches Castaño

Master's Theses

Vocal learning is rare among animals but is well developed in parrots, which can imitate novel sounds and, in captive settings, reproduce human speech. This study helps address a larger evolutionary question about vocal learning. Specifically, whether vocal learning ability is best understood as a single generalized trait or as a multi-dimensional system in which different acoustic features can be learned and reproduced with varying degrees of fidelity. This thesis quantifies how closely companion parrots match their human tutors across three acoustic dimensions (spectrographic structure, intensity contour, and pitch contour) and tests whether mimicry accuracy varies among individuals, differs between …

Investigating The Taxonomic Uncertainties Of Potentilla Rupincola, Natalie Elizabeth Hieber

Master's Theses

Landscape stewardship is an integral role for land managers that becomes more important when rare or endangered species occur within managed areas. Conservation across the landscape is a primary concern for land managers, but resources allocated for conservation can be limited due to many competing goals. Taxonomic uncertainty surrounding rare and endangered taxa, particularly plant taxa, that have historically been classified solely using morphological features further complicates conservation planning. One such taxon is Potentilla rupincola, a rare plant endemic to the eastern Rocky Mountains in Colorado. For over a century, botanists have debated whether P. rupincola is a distinct species …
