Long-Term Compositional Shifts In The Fish Community Of The Wabash River, Olivia R. Wertman

Masters Theses

There is concern about declining biodiversity in the world today and an increasing need to monitor biodiversity through collecting data and gauging changes occurring in biodiversity over time. Large river fish communities are one area of particular interest due to their sensitivity to environmental changes. One program seeking to address this is the Long-Term Survey and Assessment of Large River Fishes, LTEF, which monitors fish populations in the large rivers of Illinois. In this study, I assessed changes in the fish community of the lower 322 km of the Wabash River from 2010-2025 using annual direct current boat electrofishing surveys …

If You Build It, Will They Stay? Fish Communities Continue To Utilize Restored Habitat A Decade Following An Instream Restoration, Alexis L. Vandenberg

Masters Theses

Lotic ecosystems are degraded at an alarming rate due to anthropogenic activities. In order to combat these changes, stream restorations are implemented to improve conditions such as water quality, habitat heterogeneity, and bank stability. However, the impacts of these restorations are often understudied and long-term impacts are unknown. Restorations are typically designed to be ‘fish attractors’; this idea is known as the ‘Field of Dreams hypothesis’ – ‘if you build it, they will come’. This study uses data collected in Kickapoo Creek, Coles County from 2009 to 2015 and again in 2021 and 2022 to assess the long-term impacts of …

Compositional And Functional Shifts In Fish Community Structure In Response To Low-Head Dam Removals, Joshua D. Bruegge

Masters Theses

Low-head dams serve as intermittent barriers to aquatic connectivity and directly alter both upstream and downstream habitats and biotic communities. In 2018 and 2019, two low-head dams in the Vermilion River watershed of eastern Illinois were removed, reconnecting over 1,700 kilometers of upstream habitat within the basin. To determine the impacts of these dam removals, fish community surveys were conducted at 12 fixed sites across three reaches in two rivers from 2012-2022. This study assessed reach-specific temporal responses of the fish community and habitat characteristics. I linked trait expressions within the fish community to abiotic variables using the co-inertia RLQ …

Epigenetic Modifications In Dedifferentiated Liver Cells To Restore Lost Liver Function, Shreya Sharma

Masters Theses

The goal of the study is to investigate whether the epigenetic modifications can enhance the restoration of liver gene expression in dedifferentiated hepatoma cells or not. For the study, we used dedifferentiated H11 hepatoma cell lines which overexpress one of a panel of introduced candidate liver-enriched transcription factors H11-HNF1a, H11-CREB3L3, H11-CREG1, H11- HHEX, H11-HNF6, and H11-IGFBP1. The cells were treated with the DNA methyltransferase inhibitor 5-azacytidine and the histone deacetylase inhibitor sodium butyrate, both individually and in combination. Gene expression analysis was determined by RT-qPCR, which revealed that while transcription factor overexpression alone produced limited activation, epigenetic modulation, particularly Histone …

A Polyphasic Investigation Of Terrestrial Green Algal Diversity Of Biological Soil Crusts From The California Channel Islands, Emily Masluk

Masters Theses

Biological soil crusts (BSCs) in arid and semiarid environments support diverse microbial communities that contribute to soil stabilization, nutrient cycling, and ecosystem resilience. Among these organisms, terrestrial green algae are taxonomically challenging due to their simple morphology, phenotypic plasticity, and lack of diagnostic life history traits. This study investigated the diversity and taxonomy of green algae from BSCs collected on San Nicolas Island, San Clemente Island, and Santa Barbara Island using the polyphasic approach integrating morphology, phylogenetic analyses, molecular analyses, and ecological data. A total of 198 strains were isolated, of which 79 green algal strains underwent molecular analysis using …

Complex Cyanobacteria Biopriming Effects On The Growth Of Mojave Desert Restoration Plant Species At Differing Life Stages, Ashley R. Brumit

Masters Theses

Seeding practices are an important tool for land managers to restore habitats following disturbances, but large-scale seeding efforts often fail. One option is to bioprime seeds with native microorganisms such as cyanobacteria. However, biopriming studies have yet to be conducted in American deserts, and only one previous study compared the effects of heterocystous and non-heterocystous cyanobacteria biopriming. The objective of my work was to evaluate the effects of seed biopriming on plant growth of Mojave Desert plant species and comparing the effect ofN-fixing and non N-fixing cyanobacteria. One heterocystous taxon (Kalymmatonema desertorum) and one non-heterocystous taxon (Microcoleus sp.) isolated from …

Grounding Human Value: A Critical Evaluation Of Naturalism And A Defense Of Christianity As The Basis For Human Value And The Moral Status Of The Unborn, Jacob Vazquez

Masters Theses

This thesis will explore the grounding of personhood and seeks to convince atheist readers who adhere to naturalism that abortion is wrong because human beings are made in the image of God, as the Christian doctrine of the Imago Dei teaches. This will be done by taking the reader on a journey or a map, in which various secular (non-religious) destinations are visited before finally reaching the final theological conclusion as presented above. The evidence culminated from each of the secular stops will end up supporting the argument from the Imago Dei against abortion.

For instance, Chapter 1 will consist …

The Ultra Dilemma: Understanding The Impact Of Ultra-Processed Food, Cassia Elizabeth Brenning

Masters Theses

Ultra-processed food dominates the market, making up an estimated 73% of the national food supply and costing 52% less than healthier, minimally- processed alternatives (Ravandi et al). With such a large supply, there is a great demand to sell these products to consumers. Major food corporations rely on misleading labels, heavy marketing, and industry-funded research to manipulate consumers into buying more of their products. While these products are cheap, quick, convenient, and delicious, they are not components of a healthy diet.

This thesis argues that the best way to tackle the issue of ultra-processed food is by redirecting focus from …

Hollywood, Ai, And The Moral Universe: An Analysis Of The Terminator And Battlestar Galactica, Lara Sumera Samms

Masters Theses

This thesis defends the argument that depictions of artificial intelligence in Hollywood film and television point to a moral universe. Films The Terminator (1984) and Terminator 2: Judgment Day (1991), as well as the television series Battlestar Galactica (2004-2009) are analyzed to find clues of moral facts. This research paper submits that these stories add weight to the moral argument and provide evidence that humans implicitly recognize a moral universe. Such acknowledgment of moral structures cannot be adequately explained within a secular framework such as utilitarianism or evolutionary ethics. However, the Christian worldview frames reality around the existence of God, …

The Divided Self: Gothic Duality In Literature, Sarah Anna Meeks

Masters Theses

Gothic literature of the nineteenth century is haunting due to its frequent use of ghosts and monsters. However, the true terror lies in a deeper horror, one that is more intimate and destabilizing– a fright that leaps out of the text, looking into the heart of the reader: the fractured mind of the self torn between reality and repression, haunted by its own, newly manifested internal disunity rather than external monsters. The characters of Gothic fiction are typically caught in a psychological turmoil. They battle with split morals between duty and desire, morality and madness, and science and spirituality. Specifically, …

Exploring The Relationship Between Loneliness And Real-Time Measurements Of Gsr And Hrv During Concept Mapping, And Cortisol And Oxytocin Levels, Jangwon Seo

Masters Theses

This study attempts to explore loneliness among college students from a bio-physio-psycho-social perspective, and it utilizes real-time physiological measurements (GSR and HRV) and biomarkers (cortisol and oxytocin) in conjunction with psychosocial assessments. The study employs both qualitative and quantitative methods, which involve concept mapping exercises, with the aim of comprehending the full nature of how loneliness interacts with physiological and psychological processes. At Time 1 (T1) we found significant positive correlations between loneliness and elevated GSR levels, which is indicative of increased sympathetic arousal (r = .35, p < .01). Additionally, there were significant negative correlations between loneliness and mean RR intervals in HRV that indicated autonomic dysregulation featured by increased sympathetic activities as well as reduced parasympathetic functions (r = -.28, p < .05). However, at Time 2 (T2), these correlations were not significant indicating possible temporal fluctuations due to adaptive responses or extraneous variables such social support systems or coping mechanisms. The qualitative data from concept mapping enriched the analysis by providing deeper insights into the cognitive and emotional processes underlying loneliness. Despite limitations like demographic skewness, funding constraints, logistical challenges, etc., this, therefore, highlights the need for multidimensional investigations of psychological phenomena. This has implications for future research as well as clinical practice, which could include using these integrative measures to develop holistic interventions for mental health disorders.

Neurogenesis And Functional Recovery Of Murine Retinal Ganglion Cells After Glaucoma Induction Following Treatment With Pnu-282987, Samantha Luzadre

Masters Theses

Experiments were performed to demonstrate electrical recovery in glaucoma-induced adult mice after neurogenesis of retinal ganglion cells (RGCs). Newly derived RGCs were induced following eye drop treatment with a selective alpha7 nicotinic acetylcholine receptor agonist, PNU-282987. Both sexes of transgenic (RlbpCre-ER (CRE⁺) and Rosa-tdTomato (tdTomato⁺)) adult mice were utilized to trace newly generated RGCs originating from Müller glia (MG). Experimental mice were injected with hypertonic saline into the episcleral vein of anesthetized mice to significantly increase intraocular pressure (IOP) and induce glaucoma-like conditions. One month after the injection and after significant death of RGCs occurred, mice …

An Investigation Of Collateral Activity Effects On Behavior Maintained By A Drl 72‑Second Schedule, Cassidy M. Graham

Masters Theses

Impulsivity is a key behavioral trait with broad implications for clinical disorders such as Attention Deficit Hyperactivity Disorder ADHD, and substance use disorders SUD, where impaired inhibitory control contributes to maladaptive outcomes. In preclinical research, animal models provide valuable tools for examining behavioral processes associated with impulsivity. The Differential Reinforcement of Low Rates (DRL) schedule, offers a precise measure of response inhibition and timing by requiring subjects to withhold responses for reinforcement. This study employed DRL72s schedule to investigate impulsive action in male and female Sprague-Dawley rats, with an emphasis on sex-based differences and the potential influence of environmental factors. …

"Gross Normality" And "Marked Deviation": A Qualitative Study Of Disability Theory In Three Periods Of Sociological Literature, Kelsey Sullivan

Masters Theses

In the 20th century, three theoretical perspectives concurrently dominated sociological discussions of disability. Functionalism and Talcott Parsons argued for a pathologized framework in the form of a “sick role” occupied by disabled people. Interactionism and Erving Goffman emphasized the stigmas faced by individual disabled people, and the ripple-effects of those stigmas. Finally, disabled activists, inspired by social constructionism, championed the social model of disability. This model purported that disability is a social condition, resulting from systemic barriers imposed upon people who do not fit the mental or physiological norm. This project, through a content analysis of 30 historical journal articles, …

Masters Theses

The purpose of this qualitative, instrumental case study was to identify the content for an interdisciplinary course about music and the brain that educates collegiate students about the benefits of lifelong music engagement. Despite increasing awareness of musical relevance to the human brain, many institutions of higher learning continue to teach music as its isolated area of study without connecting it to other fields that could benefit from incorporating it or vice versa. The sample size consisted of four to seven experts that were either community experts or Liberty University faculty in the fields of science, medicine, or music within …

Investigation Of A Divergent Triangle Construct For Internal Fixation Of Vertical Femoral Neck Fractures Using Experimental And Finite Element Analysis Methods, Hannah Rainey

Masters Theses

Hip fractures are a significant public health issue as they are a commonly encountered problem and have a high rate of mortality. The fracture of the femoral neck is difficult to treat due to the geometry of the proximal femur and the weight-bearing capacity that the structure must comply with. Internal fixation of the femoral neck is often accomplished with three screws inserted along the axis of the femoral neck. The optimal configuration and number of these screws is not agreed upon in the literature. The purpose of this study was to conduct a pilot investigation on the biomechanical performance …

Early Detection Of Oak Wilt Using Unmanned Aerial Vehicles (Uav) & Computer Vision, Muttaki I. Bismoy

Masters Theses

Forests are critical ecosystems, delivering services such as biodiversity conservation, climate regulation, timber production, and recreation. However, they face increasing threats from pathogens like Bretziella fagacearum, which causes Oak Wilt, a lethal disease that disrupts water transport in oak trees, leading to canopy dieback and eventual death. Traditional detection methods rely on manual ground surveys, which are labor-intensive, time-consuming, and prone to error, particularly in early disease stages.

This research presents an automated, scalable, high-precision Oak Wilt detection system using Unmanned Aerial Vehicles (UAVs) combined with deep learning-based computer vision. Expanding on earlier work with a lightweight CNN achieving an …

Determining The Origin Of An Isolated Great Lakes Plant Species, Agoseris Glauca (Asteraceae), Seth Paul Hiers

Masters Theses

Small, isolated populations often have low genetic diversity and low potential for adaptation in response to environmental changes. Alternatively, isolated communities are often more likely to display local adaptations and over time speciate. The Great Lakes Region is home to over 50 vascular plant species that are disjunct from the species’ core populations. Agoseris glauca (Asteraceae) is a Great Lakes disjunct and Michigan state threatened species geographically isolated from its core range by 900 km. This study uses Genotyping by Sequencing to assess the population genetics of A. glauca for two Michigan disjunct populations and five western populations in the …

Assessing Greenhouse Gas Emissions From Michigan’S Drowned River Mouths Using In Situ And Remote Sensing Methods, Jillian A. Greene

Masters Theses

Freshwater estuaries are natural contributors to the carbon cycle including production and emission of methane (CH4) and carbon dioxide (CO2), potent greenhouse gases (GHGs); however, estimates of their contribution to regional and global GHG emissions is largely unconstrained. Few studies have examined the quantification and drivers of lake CH4 and CO2 production in the Great Lakes region and how it may differ in response to anthropogenic development. In this study, CH4 and CO2 emissions were measured from three drowned river mouth estuaries (DRMs) along the eastern shore of Lake Michigan in 2024. The DRMs exist along a latitudinal gradient ranging …

Investigating Food Web Dynamics Of Great Lakes Coastal Wetlands Using A Novel Stable Isotope Approach, Alyssa M. Smith

Masters Theses

Coastal wetlands of the Great Lakes support abundant populations of fish, invertebrates, and vegetation, though the trophic linkages connecting primary production and lower consumers is not well understood in these systems. We implemented a multiple-tracer approach, pairing traditional food web isotope tracers like carbon (δ13C) and nitrogen (δ15N) with total mercury concentrations (THg). We predicted that filamentous algae would be the dominant energy resource in the diet of lower trophic-level invertebrates in the Grand River Estuary, a network of riverine coastal wetlands adjacent to lake Michigan. In addition, we predicted that adding THg as a tracer would improve the resolution …
