Distribution Of Mussels In Tributary Systems Of The Lower Ouachita River Watershed, Zach R. Crain

ATU Theses and Dissertations 2021 - Present

Freshwater mussel communities in small tributary streams are poorly documented in Arkansas, limiting the understanding of how diversity is structured across river networks. To address this data gap, we surveyed 147 sites across five previously unsurveyed watersheds in the South-Central Plains Ecoregion (SCPE). We sampled 5,473 individuals representing 17 species, including four Arkansas Species of Greatest Conservation Need (SGCN). We evaluated patterns in community variation utilizing β-diversity based on both presence-absence and abundance data. Overall turnover (βsor and Bray) was partitioned into replacement (βsim and BrayBal) and nestedness (βsne and BrayGra) components. Replacement and nestedness each drove turnover in two …

Determining Cave Presence And Diet Variation Of The Ozark Big-Eared Bat (Corynorhinus Townsendii Ingens) From Guano Dna, Lark E. Sybrant

ATU Theses and Dissertations 2021 - Present

The Ozark big-eared bat (Corynorhinus townsendii ingens; OBEB) is federally endangered in Arkansas, where it persists in a few small, geographically restricted populations within the Ozark National Forest. Although the region contains many caves that appear suitable for OBEB, expanded survey efforts are needed to locate additional roost sites for monitoring and protection. Effective conservation also requires a clear understanding of their distribution and diet. Traditional cave surveys can be disruptive and often miss cryptic species, and earlier diet studies based on manually sorting prey remains provided only coarse taxonomic resolution and overlooked soft‑bodied insects. To address these …

Re-Evaluating The Safety Of Erythritol: A Critical Review Of Emerging Evidence, Kaitlyn B. Kirchner

Honors Thesis

Erythritol, a commonly used non-nutritive sweetener, has gained popularity as a sugar alternative due to its low caloric value and minimal effect on blood glucose levels; however, emerging research has raised questions about its overall safety. This literature review critically evaluates current peer-reviewed evidence on the effects of erythritol on the cardiovascular and gastrointestinal systems. Findings indicate that erythritol is generally well tolerated in the gastrointestinal tract, with fewer adverse effects than other sugar alcohols due to its rapid absorption and limited fermentation, although symptoms may be dose-dependent and influenced by co-ingestion with other carbohydrates. In contrast, evidence related to …

Producing Oral Medicines In Lettuce To Fight Chronic Diseases, Carlos E. Balmaceda, Megha Goyal, Anubhav Pal

Create@State

Chronic diseases, such as inflammatory bowel diseases, require patients’ commitment to their treatment, which can be challenging over time. Edible plants could help address this challenge by acting as living factories that produce a range of drugs, including medicinal proteins. Patients could eat the plants because their cells have a sturdy outer layer that protects and helps deliver the medicine. Lettuce is an example of a common vegetable that can serve this purpose. The main goal of this project is to develop a medicinal protein production and oral delivery system using lettuce plants. We will build a small version of …

A Sturdy Future: Mangrove Restoration Against Climate Extremes, Gabriella Marie Siasoco

Student Theses 2015-Present

This paper addresses the impacts of climate change on natural disasters and examines how rehabilitation of mangrove forests in Mesoamerica and the Caribbean can mitigate those effects. Rising ocean and atmospheric temperatures contribute to higher sea levels and more severe hurricanes and tropical storms, characterized by increased frequency, duration, and intensity in peak winds, storm surges, and rainfall. Mangrove ecosystems act as vital buffers against coastal disturbances such as tsunamis and extreme storms, while contributing to climate change mitigation through carbon sequestration. Additionally, they improve water quality by filtering nutrients, preventing eutrophication. Despite their ecological and economic value, mangroves in …

Associations Between Levels Of Physical Activity And Cognitive Health, Gemma Goldenbaum

Honors Theses

The purpose of this study is to examine the relationship between physical activity levels and executive function, specifically focusing on inhibitory control and working memory capacity. Though the benefits of exercise on brain health are well-documented, the extent of cognitive differences between sedentary individuals and elite student-athletes remains misunderstood. Eighty participants (ages 18–35) were categorized via the International Physical Activity Questionnaire (IPAQ) into sedentary, low, and advanced activity tiers. Participants completed computational assessments, including the Operation Span (OSPAN) task for working memory and Go/No-Go tasks to measure response inhibition and implicit associations.

Bio 340 Final Project: Effects Of Light Pollution On Bat Activity, Cael Schneider

Biology Student Scholarship

Cael Schneider - Environmental Biology ‘28

Artificial light at night (light pollution) is an increasing consequence of urbanization and can disrupt nocturnal wildlife. Bats are especially susceptible, as they rely on dark skies for navigation, predator avoidance, and foraging. The effects of artificial light may vary among species due to differences in foraging strategies, habitat use, and light tolerance.  Previous research has documented negative effects of artificial light on bat foraging, roosting, breeding, and hibernation. However, some species, such as red bats, may forage near artificial lights where insects are abundant. Species including the big brown bat, hoary bat, and …

Windows Of Developmental Susceptibility To Tetrahydrocannabivarin (Thcv) Reveal Stage-Dependent Morphological And Biological Effects, Mirielle Clayton

Honors Theses

Tetrahydrocannabivarin (THCV), a minor cannabinoid found in Cannabis sativa, is gaining attention for its potential therapeutic applications, yet its effects on early development remain poorly understood. This study investigated how the timing of THCV exposure influences morphological, behavioral, and bioaccumulation outcomes in zebrafish (Danio rerio) embryos. Embryos were exposed to 2 μM THCV during discrete developmental windows (6–30, 30–54, 54–78, 78–102) and continuous 6–102 hours post-fertilization (hpf), designed to model early stages of human gestation. Behavioral analysis using a larval photomotor response assay revealed significant reductions in locomotor activity during dark phases, with the strongest hypoactivity observed …

Evolution Of Nematode Prey Chemotaxis Behavior Across Different Environments, Hailey R. Smith

Honors Theses

Climatic conditions in the near future are projected to be warmer, with more frequent and intense weather events. This will substantially alter the environments in which organisms must integrate specific information to find essential resources. Many organisms rely upon chemical signals to orient towards attractive resources through a mechanism called chemotaxis. How different environmental conditions, like temperature, impact this process will be important to understand as environments change. I conducted a laboratory evolution experiment with the model nematode Caenorhabditis elegans to see how success in chemotaxis assays changes over time when selected under different temperature regimes (normal laboratory temperature, increased …

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 …

Impacts Of Salinity On Microbial Enzyme Activity In Coastal Waters, Natali Ariyoshi

Honors Theses

Microbial extracellular enzymes are critical for the breakdown of organic matter and nutrient cycling in aquatic ecosystems. Extracellular enzyme activity serves as an indicator of nutrient turnover rates, metabolic states, and nutrient limitations within an ecosystem. Coastal ecosystems are especially dynamic as the influx of freshwater from inland runoff or seawater intrusion from storm surges can lead to fluctuations in salinity which can restructure microbial communities and alter enzymatic activity. Despite the ecological significance of these changes, few studies have explored the effects of short-term salinity shifts on microbial extracellular enzyme activity in coastal waters. This study investigated the effects …

Effects Of Increased Salinity On Mississippi Coast Bacterial Community Composition And Diversity, Clifton C. Wade

Honors Theses

Bacterial communities are important to ecosystem function in coastal environments, but the response of these communities to short term increased salinity conditions is understudied. This study utilized a microcosm setup to investigate the response of coastal seawater bacterial communities to three treatments: an unamended seawater control, a reference treatment that received reverse osmosis (RO) water, and an elevated salinity treatment that received artificial seawater dissolved in RO water. Microcosms were sampled four times over a five-day period to analyze the effects of time under different salinity conditions on the seawater bacterial community. 16S rRNA gene sequencing was used to analyze …

Studying More, Not Less: Rethinking Test Anxiety In Undergraduate Biology Courses, Kailey E. Reeves

Honors Theses

This study investigates the relationships among test anxiety, study behaviors, and metacognitive evaluation in undergraduate biology courses. While prior research has established that study strategies and metacognition influence academic performance, less is known about how these factors interact with test anxiety in undergraduate Biology courses. Guided by the student approaches to learning (SAL) and metacognition frameworks, this study examines whether test anxiety is associated with the type and number of study strategies students use, as well as their ability to evaluate their own learning and preparedness. Using a convergent parallel mixed-methods design, data was collected from 205 students enrolled in …

Bax Activation Through The N-Terminal Bh3-Like Domains Of Vdac1 And Vdac2, Autumn A. Peters

Honors Theses

Voltage-dependent anion channels (VDACs) are central to mitochondrial function by mediating metabolite diffusion across the mitochondrial outer membrane (MOM). Two isoforms­­­­­­­­­­­,­­­­­­­­­­­­­­­­­­­­­­­­­­­­ VDACs 1 and 2, are also implicated in apoptosis based on interactions with Bcl-2 family proteins that control this process, including Bax and Bcl-xL. Activation of the pro-apoptotic protein Bax by interaction with ‘BH3-only’ proteins, such as Bim or Bid, induces MOM permeabilization to signal apoptosis, yet accumulating evidence indicates VDACs 1 and 2 may also affect Bax. We discovered that the VDAC N-terminal domains contain high sequence similarity to the conserved BH3 domains within Bcl-2 family members that …

A Survey Of Lichen Native To Three Of Mississippi’S National Forests, William S. Granberry Iii

Honors Theses

Lichens are a major part of the environment for telling the air quality and the impact humans have on the environment. These signs go into how many species of lichen are present in a general area, and there has been a lack of a list of lichens that call Mississippi their home. The goal of this research is to help create this list through a survey of lichen in three of Mississippi’s National Forests: DeSoto, Homochitto, and Holly Springs. These three forests are ideal because they cover differing ecosystems and are in different parts of the state, heightening the chance …

Mechanisms Underlying Diversity In Bacterial Biofilms, Jacob David Holt

Dartmouth College Ph.D Dissertations

Bacteria commonly exist in natural environments as communities of multiple strains and species attached to surfaces and encased in an extracellular matrix of DNA, protein, and polysaccharides–termed biofilms. These biofilms contribute to diverse functions, from ocean carbon cycling via chitin degradation to pathogenic processes such as wound or implant colonization. The molecular mechanisms governing biofilm formation and composition have been well characterized in model pathogenic organisms, yet the extent to which aspects of biofilm formation contribute to the assembly and maintenance of diverse communities remains less well understood. Using microfluidics, confocal microscopy, and model biofilm-forming bacteria, this thesis details how …

Green Infrastructure As A Strategy For Revitalizing Old Residential Neighborhoods: Evaluation Of Carbon Footprint And Energy Performance - Case Study Of Heliopolis, Cairo, Ahmad Abouisaadat, Eman Gameel, Shoroq Adel

Mansoura Engineering Journal

This study aims to address the challenge of reducing energy consumption and greenhouse gas (GHG) emissions in urban areas, particularly in aging residential neighborhoods. Despite the benefits of Urban Green Infrastructure (UGI) and residential retrofitting, current research often examines these strategies separately, leaving a gap in understanding their combined impact at the district scale. The research proposes a methodology that integrates GIS-based spatial analysis, Urban Building Energy Modeling (UBEM), and Life Cycle Assessment (LCA) to evaluate the effects of UGI (e.g., green roofs, urban trees) and retrofitting strategies on energy use, CO2 reduction, and urban microclimates. The study will provide …

A Doubly Stochastic Model Of Government Interventions To Preserve Ecosystems Services In The Context Of Large-Scale Industrial Agriculture, Karma Brame, Wendy Calderon, Kaylee Clark, Josh Hiller, Natalia Negrete

Spora: A Journal of Biomathematics

Deforestation, driven by industrial agriculture and cattle farming, has significantly impacted communities and ecosystems across the globe. In this paper, we develop a discrete-time Markov model to evaluate the effectiveness of market-based interventions, such as payments for ecosystem services (PES) and taxes, in addressing forest loss within the context of large-scale agriculture. Specifically, we focus on how commodity price variability influences deforestation decisions. To model these price fluctuations, we represent agricultural prices as geometric Brownian motion (GBM). By linking commodity price dynamics to land use transitions, our model aims to provide insight into how financial mechanisms can slow or stop …

Functionalized Nanodiamonds As Binding Platforms For Single-Stranded Dna, Mallory A. Chapman

Honors Theses

Nanodiamonds (NDs) offer a promising platform for biomolecular applications due to their stability, biocompatibility, and three-dimensional structure. This study focused on developing a nanodiamond–DNA complex in which streptavidin-functionalized NDs would form a protective shell around biotinylated single-stranded DNA (ssDNA), creating a core–shell system like an “M&M” candy with DNA at the center and a protective coating on the outside. DNA has many uses in nanotechnology, including DNA origami, nanomachines, and drug delivery systems, but its degradation limits its practical use, making protective strategies essential.

ND–DNA conjugates were prepared using biotin–streptavidin interactions and analyzed using gel electrophoresis. Initial separation on agarose …
