Developing A Range Prediction For The Imperiled Florida Harvester Ant (Pogonomyrmex Badius) Using Species Distribution Modeling, Noah Williamson

Honors Theses

The Florida Harvester Ant (Pogonomyrmex badius) was once widespread and commonplace throughout the sandhills of the Southeastern United States, providing key ecosystem services, such as seed dispersal and soil aeration. Over recent decades, however, Florida Harvester Ant populations have declined in some areas. Current literature postulates that Red Imported Fire Ants (RIFA), and the insecticides used to manage them, as well as further human encroachment onto their habitat, all likely contributed to Florida Harvester Ant population declines. Thus, to better protect these organisms, pursue data-driven conservation efforts, and guide management practices, more information about their nest site selection, as well …

The Impact Of Pp1Β Cancer-Associated Polymorphisms On Pp1Β Protein Abundance And Cell Survival In Humanized Saccharomyces Cerevisiae, Kaylee Martinez

Honors Theses

PP1β is an understudied protein phosphatase that affects the cell’s ability to reproduce. It has been known to be an important part of the cell cycle. Mutations within PP1β have been found to affect that process and influence the development of cancer and disease. In this thesis, different PP1β cancer and disease associated polymorphisms are investigated through the use of humanized yeast. PP1β yeast variants are tested by using Live/Dead cell assay and western blot techniques. Live/Dead analysis was conducted on different strains grown at permissible temperature (room temperature) and non-permissible temperature (37°C) over the course of 6 or 48 …

Detection And Quantification Of Allergen Cross-Contact In Shared Frying Oil Using Targeted Mass Spectrometry, Francisca Asigri

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Cow’s milk and egg allergies are prevalent IgE-mediated food allergies that pose significant public health concerns worldwide. Although strict avoidance remains the primary management strategy, unintended exposure can still occur through allergen cross-contact, particularly in commercial and industrial food operations that utilize shared frying oils. The objective of this study was to identify and quantify allergen transfer in shared frying oil and assess the robustness of existing targeted mass spectrometry methods (LC-MS/MS) for detecting milk and egg proteins in heated oil matrices.

Heated oil spikes were developed by incorporating non-fat dry milk (NFDM) and whole egg powder (WEP) into oil …

Start With What They Know: Using Motivational Interviewing To Create A Cooking Class, A Culinary Intervention For Teens (Autistic And Non-Autistic), Gwendolyn S. Tedder

LEND Trainee Presentations

Autistic teens are at greater risk for having heart disease and diabetes as adults. Food particularity, sensory issues, fixed mindset, and anxiety over trying new things can slow down their interest in preparing food for themselves. Nurturing basic cooking skills and gently encouraging trying new foods would provide more nutritional options to teens as they move into adulthood. A cooking class preceded by Motivational Interviewing (MI) developed further interest in preparing food afterward in teens, both autistic and non-autistic, and in trying new foods for autistic teens with food concerns.

Folic Acid–Carbon Dot–Gemcitabine Nanoparticles For Targeted Cancer Drug Delivery, Irfan Huda, Hua Mei

SPARK Symposium Presentations

This project aims to develop a folic acid-attached carbon dot nanoparticle system (FA-CDs-GEM) for the targeted delivery of gemcitabine to cancer cells. While gemcitabine is widely used, its effectiveness is limited because a short in vivo half life and lack of selectivity, which lead to severe side effects. Carbon dots offer a simple and modifiable platform as the drug delivery and bioimaging agent. Conjugation of folic acid to the carbon dots enables selective targeting of cancer cells that overexpress folate receptors. In this study, we synthesized and characterized FA-CD-GEM nanoparticles and developed an HPLC calibration curve of GEM to accurately …

Human Osteosarcoma Cell Line That Overexpresses Cd4/Ccr5 Or Cd4/Cxcr4 To Study Hiv-Host Interactions, Harry Baffour Awuah

Biotechnology Theses

Human immunodeficiency virus type 1 (HIV-1) entry into host cells occurs through interactions between the viral surface envelope glycoprotein (Env) and the host receptor CD4, and co-receptors CCR5 or CXCR4. However, understanding these interactions in membrane contexts remains limited due to low receptor and coreceptor densities in commonly used cell models. To address this, we developed cellular systems with elevated CD4 expression and either CCR5 or CXCR4. Human osteosarcoma cells (HOS), which lack endogenous surface expression of HIV receptor (CD4) and co-receptors (CCR5 or CXCR4), were engineered via lentiviral transduction to overexpress CD4 and either CCR5 or CXCR4. Cells were …

A Test Case For Raccoon Roundworm Anthelmintic Baiting In Western Virginia, Karen Powers, W. Jayme Viers, Carolyn K. Rossmeisl, L Kristen Page

Virginia Journal of Science

As a test case to determine the efficacy of anthelmintic baiting to reduce raccoon roundworm (Baylisascaris procyonis) prevalence in western Virginia, we deployed baits in a mountainous area of Roanoke Co., Virginia that historically was occupied by Allegheny woodrats (Neotoma magister). We deployed anthelmintic baits at 6-wk intervals from August to December 2024 at a density of 100/km². We opportunistically collected raccoon (Procyon lotor) scat in the drop area from August 2024 to May 2025 and found a marked decline in prevalence of raccoon roundworm in the samples. Deeming this a measured …

Production Of Black And Navy Beans In Virginia, Harbans L. Bhardwaj, Satya S. S. Narina Ph.D.

Virginia Journal of Science

An urgent need exists in Virginia and adjoining states to identify crops to replace declining tobacco acreage. Although not traditionally grown in the region, dry beans (Phaseolus vulgaris L.) have considerable potential as alternative summer crops due to their nutritional benefits and increasing consumer demand. Information on the production potential of these crops in Virginia, however, is not yet available. To remedy this situation, replicated field trials were conducted over three years with six black and four navy bean varieties to characterize grain yields following three row spacings and three planting times. Black beans significantly out-yielded navy beans (2095 …

Enhancing Urban Garden Capacity By Linking Biodiversity And Ecosystem Function, Mary T. Nguyen, Carleen Rauh, Shelby Gresch, Charlotte Correiro, Heidi Elmendorf, Adriane Fugh-Berman, Gina Wimp, Alexandra L. Decandia

Virginia Journal of Science

Urban agriculture broadly describes food and plant cultivation in metropolitan areas. While biodiversity is thought to support ecosystem health and resilience, the relationship between above-ground and below-ground diversity has been understudied in urban green spaces. This study examines plant, animal, bacterial, and fungal diversity across three distinct urban habitats: a turf lawn, a forb garden, and a farming space. Using bacterial 16S rRNA and fungal ITS2 sequencing, soil nutrient analyses, and surveys of vegetation and wildlife, we connect diverse philosophies in urban agriculture to their role in advancing community diversity and ecosystem function. We found that different urban gardens support …

Designing Surface-Induced Entatic States In Copper Complexes For Tunable Reactivity, Rachel Kiser

Senior Theses

Copper catalysts play an important role in electrocatalytic oxidation reactions due to their redox flexibility and relative abundance compared to noble metal catalysts. In biological systems, copper metalloenzymes often achieve enhanced reactivity through an entatic state. Entasis is described as an active site or metal center being constrained to a geometric and electronic state, minimizing primary sphere reorganization energy and achieving higher rates of electron transfer.  This study investigates whether entasis can be achieved in synthetic molecular catalysts by immobilizing Cu(I) complexes onto metal oxide surfaces. Two Cu(I) complexes bearing carboxylate-functionalized ligands were examined both in homogeneous solution and when …

Interspecific Overlap In Seabird Diet Throughout The Breeding Season, Alexis V. Berkey

Student Publications

Seabirds are central-place foragers that breed in multi-species colonies, providing an opportunity to study species coexistence. I quantified interspecific competition among four seabird species (common terns Sterna hirundo, Arctic terns Sterna paradisaea, Atlantic puffins Fratercula arctica, black guillemots Cepphus grylle) breeding in the Gulf of Maine in 2022, 2024, and 2025. I hypothesized that, throughout the breeding season, 1) seabird diet would change and 2) interspecific overlap in diet would increase. I compared diets across species and time using direct observation of prey feeds and stable isotope values of seabird egg membranes and blood, which provide …

Cognitive Warfare: Generative Ai, False Realities, And International Humanitarian Law, Gary Corn

Joint PIJIP/TLS Research Paper Series

This paper, written as a draft chapter for the Lieber Institute for Law and Land Warfare's forthcoming book on International Law and Artificial Intelligence in Armed Conflict: The AI-Cyber Interplay, explores the IHL implications of a specific subfield or category of AI—Generative AI (GenAI). This new and rapidly evolving technology does not merely analyze or classify data; it also generates original image, audio, and video content. This synthetic content can be highly deceptive and manipulative, as in the case of so-called “deepfakes.” Combined with other information and communications technologies (ICT) and AI capabilities, GenAI has the potential to drastically transform …

Long Live The Good King: A Niebuhrian Analysis Of Arthur’S Ethical Kingship In The Once And Future King, Camille Bewley

Tenor of Our Times

The classic The Once and Future King, written by T.H. White, is a selection of four fantasy novels with one, linear plot: the story of Arthur, the mythological King of England. Reinhold Niebuhr’s book Moral Man and Immoral Society details the Christian realism of a world in need of justice without the ability to achieve perfect application. Through good education, Arthur is well endowed with Niebuhr’s requirements for a functional society: knowledge, honor, wisdom, and compassion. Such king-like qualities make him one of the most influential mythological characters in history, and a grand exemplar for maintaining ethical goals and personal …

Differential Effects Of Veratridine And 5-Fluorouracil On Ubxn2a-Targeted Mortalin And Rictor Proteins In Patient-Derived Colorectal Cancer Cells, Kate S. Schraufnagel

Honors Thesis

Colorectal cancer (CRC) is a leading cause of cancer-related mortality, particularly in patients with metastatic CRC and/or those who have developed resistance to conventional chemotherapy. There has been a significant rise in early-onset CRC (EOCRC) incidences in patients under age 50. Due to lack of screening, these patients are commonly diagnosed in the later stages where there is a lack of effective therapies. This highlights the need for targeted therapies that address the molecular drivers of tumor progression and treatment resistance. UBXN2A is a tumor suppressor protein that regulates key oncogenic pathways in CRC, including Mortalin-2 (mot-2)-mediated p53 suppression and …

Streptococcus Mutans And The Plaque Microbiome: Implications For Targeted Therapies For Dental Caries, Cooper Barton, Navi Gill Dhillon

Bioinformatics

Abstract:

Dental caries is a highly prevalent, biofilm-mediated disease driven by dysbiosis within the supragingival plaque microbiome. Although Streptococcus mutans has traditionally been regarded as a primary cariogenic pathogen, advances in microbiome research underscore the importance of community-level interactions and collective metabolic activity in disease progression. This literature review synthesizes current evidence on the ecological role of S. mutans, the functional dynamics of plaque biofilms, and emerging therapeutic strategies targeting cariogenic microbiomes. Metagenomic and metatranscriptomic analyses indicate that caries is characterized by reduced microbial diversity and a shift toward acidogenic and aciduric metabolic pathways across the microbial community. Furthermore, …
