This study aimed to analyze the relationships between activity levels, Body Mass Index (BMI), stress levels, and depression symptoms in obese pregnant women in Arkansas. Two separate exercise intervention studies were combined in this analysis to ultimately give a sample size of 293 pregnant women who were randomized into standard of care group (control) and an exercise group (treatment/experimental) (n = 115 and n = 178, respectively). Women in the control groups were instructed to independently continue to follow the physical activity guidelines recommended by their gynecologist, whereas the experimental groups participated in a combination of aerobic and resistance exercise …

Exploratory Evaluation Of Handler Performance And Processing-Related Outcomes During Cattle Handling, Morgan Marquardt

Department of Animal Science: Dissertations, Theses, and Student Research

Animals have several critical roles in society, including the production of food and fiber, and companionship. Contact with animals has been shown to benefit human physical and mental health, yet little research has investigated the impact that humans have on animals. Handler skill may considerably affect the extent to which humans influence animal health and wellbeing, and this may be a critical consideration for animal agriculture. Objective assessment of cattle handler skill has received limited attention in the scientific literature, despite its importance to human safety and animal welfare. When compared to less skilled handlers, highly skilled cattle handlers may …

Biology

Amphibious animals, such as frogs, are found at the intersection of aquatic and terrestrial ecosystems. They may serve as keystone and sentinel species and play key roles in nutrient cycling and food webs. In recent decades, amphibians have experienced drastic population declines due to habitat loss, climate change, and disease. These declines have prompted investments in ex situ conservation and captive breeding programs, which aim to reduce extinction risk by creating assurance colonies and reintroducing individuals once threats are mitigated. A critical component of these programs is proper husbandry, which ensures the health and longevity of captive populations and their …

Epigenetic Mechanisms For Mediating The Transmission Of Prenatal Maternal Stress And Associated Neurodevelopmental Outcomes, Kaylee Vis

Senior Honors Theses

The hypothalamic-pituitary-adrenal (HPA) axis is the primary stress response system responsible for regulating cortisol release. During pregnancy, maternal stress can dysregulate the HPA axis, leading to elevated cortisol and corticosterone levels that impact fetal development. Excessive prenatal exposure to stress has been associated with alterations in fetal brain structure and function, increasing the risk for neurodevelopmental disorders such as autism spectrum disorder, attention-deficit/hyperactivity disorder, and anxiety. Emerging research supports the idea that these neurodevelopmental effects may be transmitted through epigenetic mechanisms. However, a gap remains in the literature regarding the specific mechanism of interaction between environmental stressors, heritable epigenetic information, …

Sox18 Unleashed Exploring The Transcriptomic Landscape - Differential Gene Expression Analysis Via Rna Seq In Overexpressed Sox18, Van Nguyen, Kahlie Hernandez, Monabelle Elbayeh

Posters - 2026

Cancer remains a leading cause of death worldwide, and childhood sarcomas such as Rhabdomyosarcoma (RMS) and Ewing Sarcoma (ES) are particularly aggressive with limited targeted treatment options. Despite advancements in cancer therapies, metastatic sarcomas still have a survival rate below 30%, emphasizing the need for new therapeutic targets. SOX18, a transcription factor has played a role in vascular development and endothelial differentiation, functioning as a key driver of angiogenesis. In cancer, increased SOX18 expression has been linked to dysregulated cell migration, invasion, and therapy resistance mechanisms. However, the extent to which SOX18 influences RMS and ES at the transcriptional level …

Detecting Cancer Genes Using Graph Neural Networks, Marvin Masabo Nkaka

Posters - 2026

• Cancer survival prediction is challenging due to the complexity of genomic data and limited samples especially for rarer cancer types. • To address this challenge, we developed an Artificial Neural Network (ANN) model for survival analysis using RNA-sequencing gene expression data from The Cancer Genome Atlas (TCGA). • Moreover, a key concept we investigate was how transfer learning enhanced our model’s performance especially for rarer cancer types difficult to perform accurate survival analysis due to their limited samples.

Factors Influencing Sex-Based Movement Patterns In The Banded Garden Spider, Argiope Trifasciata (Forskal, 1776), Brandon R. Marrone

School of Biological Sciences: Dissertations, Theses, and Student Research

Movement is a fundamental ecological process shaping how individuals acquire mates, secure resources, and navigate heterogeneous landscapes. In species with extreme sexual size dimorphism (eSSD), such as the orb‑weaving spider Argiope trifasciata, males and females are predicted to experience different movement pressures driven by their reproductive roles. This thesis examines how individual traits and environmental conditions jointly influence movement across both sexes. Across two field seasons, we used intensive mark–recapture methods to quantify natural movement patterns of males and females within mapped prairie plots. The first chapter tested long‑standing predictions gravity hypothesis, which posits that smaller males benefit from …

Improving Cannabis Sativa's Phytoremediation Capabilities Of Forever Chemicals Through Microbial Inoculations, Tyler S. Jolin

All NMU Master's Theses

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants that pose ecological and human health risks due to their resistance to degradation and potential for bioaccumulation. Phytoremediation has emerged as a potential strategy for mitigating PFAS contamination, and plant-microbe interactions may influence contaminant uptake and transport within plant systems. These studies investigated microbial inoculation methods and examined whether Bacillus subtilis could influence the uptake and distribution of perfluorooctane sulfonate (PFOS) in hydroponically grown hemp (Cannabis sativa L.). Plant height and stem diameter growth rates and biomass accumulation were compared across treatments with and without PFOS exposure and microbial inoculation. PFOS …

Dendrimer Nanogels With Built-In Free Radical Scavenging Enable Efficient Topical Delivery Of A Hydrophilic Antioxidant To Restore Lens Redox Balance For Cataract Treatment, Lin Qi, Huari Kou, Anna Chernatynskaya, Da Huang, Vimalin Jeyalatha Mani, Humeyra Karacal, Nuran Ercal, Hu Yang

Chemistry Faculty Research & Creative Works

Cataract is a leading cause of vision impairment worldwide and are primarily caused by oxidative stress that damages and aggregates lens proteins, leading to lens opacification. However, the eye's anatomical barriers limit the penetration and bioavailability of antioxidant therapies. To address this challenge, a dendrimer-based nanogel with a built-in reactive oxygen species (ROS)-scavenging capability developed by us was employed to deliver the antioxidant N-acetylcysteine (NAC) to the lens. NAC was loaded into a generation-5 PEGylated poly(amidoamine) dendrimer (G5-PEG-TK, termed the GPT) nanogel. The resulting NAC-GPT was characterized for its ROS-scavenging activity, bioavailability, and corneal permeability. The efficacy of NAC-GPT was …

Leveraging Aspiring And Inspiring Mentorship Relationships To Promote Stem Persistence, Rayann K. Hoppe

Honors Thesis

While several mentorship interventions for STEM students already exist, persistence and retention in STEM fields remain relatively low. Additionally, there is limited research examining the intersections between aspiring (upward) and inspiring (downward) mentorship roles.

This article aims to address these gaps by examining existing literature and mentorship frameworks, with a focus on how mentorship dynamics influence STEM persistence. Two principal findings emerge from the literature: (1) effective mentorship should be conceptualized as an interconnected ecosystem rather than a hierarchical structure, and (2) the intersection of aspiring and inspiring roles contributes to the development of identity, self-efficacy, and a sense of …

The Importance Of Body Size And Spatial Scale In Modeling Winter Bird Distributions, Carissa M. Mobley

Student Publications

Birds’ annual cycles include biologically linked breeding and non-breeding seasons, yet most research and bird atlases focus exclusively on the breeding season. There have been very few winter bird atlas projects in North America, and none have been published for the northeastern United States. Short daylight hours and harsh weather limit winter survey coverage, making species distribution models (SDMs) essential for addressing spatial gaps.

I evaluated the optimal spatial scale for SDMs across bird species differing in body size and tested whether optimal scale varies with body mass. Using 16,967 eBird checklists collected during the first winter survey period (December …

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 …
