Exploring Immune Priming In The Species Exaiptasia Diaphana, Torrence Campos

Biology Theses

Vibrio coralliilyticus is a pathogen that infects various coral species across several reef ecosystems and causes mortality within a span of a few days. With increasing temperatures, the pathogen becomes more virulent towards coral. Probiotics such as MCH1-7 have previously been used to treat infected corals before and after exposure to V. coralliilyticus. In this study, we will be using a species of sea anemone Exaiptasia diaphana in place of coral to evaluate the effects of two V. coralliilyticus strains ATCC BAA-450 and OFT6-21. It was determined that BAA-450 was more virulent. It led to immediate stress and higher mortality. …

Gender Differences In Streaming Service Adoption And Cancellation During Covid-19, Dylan Lewis

Dasyurus Hallucatus Movement Response To Fire In A Complex, Resource Rich Tropical Savanna, Ian J. Radford, Annette Cook, Natasha Harrison, Ben Corey, Roberta Bencini, Harriet R. Mills

Research outputs 2022 to 2026

The northern quoll, Dasyurus hallucatus, is part of a suite of threatened native northern Australian mammals that have inappropriate fire regimes listed as a threatening process. However, fire responses reported for D. hallucatus are inconsistent among different studies. Based on the theory that the fire response of D. hallucatus will depend partially on habitat quality, we postulate that home range in high quality savannas of the north Kimberley will be small, post-breeding male mortality low and prey resources little affected by fire. Based on previous research we hypothesised that male D. hallucatus would respond to fire more than females. By …

Genome-Wide Cline Analysis Identifies New Locus Contributing To A Barrier To Gene Flow Across An Antirrhinum Hybrid Zone, David L. Field, Sean Stankowski, Taylor Reiter, Jitka Polechova, Desmond Bradley, Daniel M. Richardson, Annabel Whibley, Arka Pal, Daria Shipilina, Louis Boell, Melinda Pickup, Yongbiao Xue, Enrico Coen, Nicholas Barton

Research outputs 2022 to 2026

Identification of the genomic regions that contribute to reproductive isolation and how they interact is a major goal of evolutionary genetics. Much effort has focused on locating candidate genes and potential barrier loci by scanning genomes for regions of excess differentiation (FST). An alternative, and perhaps more robust approach, is to scan for genomic regions exhibiting steep clines in allele frequency across a hybrid zone. We develop a computationally efficient method for approximating cline parameters for large number of loci, and apply it to genomic data from across a hybrid zone between flower colour varieties of Antirrhinum majus (A. m. …

Investigating Culicoides Diversity, Distribution, And Behavior In Arkansas, Cassandra Steele

Graduate Theses and Dissertations

Culicoides biting midges (Diptera: Ceratopogonidae) are globally important vectors of pathogens affecting livestock and wildlife. In the United States (US), transmission of bluetongue virus (BTV), epizootic hemorrhagic disease virus (EHDV), and vesicular stomatitis virus (VSV) results in economic losses and periodic mortality events of wild and domestic ruminants. Culicoides sonorensis is the confirmed vector of BTV and EHDV in the western regions of the US, however this species is uncommon throughout much of the eastern and southeastern US, where hemorrhagic diseases remain endemic. There are likely other putative vector species responsible for pathogen transmission. This research investigated Culicoides diversity, distribution, …

Loss Of Palmitoylation Impacts The Interaction Between The Organic Anion Transporting Polypeptide (Oatp) 1b1 And Oatp1b3., Cecilia E. Villanueva, Whitney M. Nolte, Priscilla Flores-Ascencio, Bruno Hagenbuch

Manuscripts, Articles, Book Chapters and Other Papers

The organic anion transporting polypeptide (OATP) 1B1 and OATP1B3 are hepatic transporters that mediate the uptake of numerous therapeutics like antibiotics and statins. Various post-translational modifications, eg, phosphorylation and glycosylation, have been shown to impact OATP1B1 and OATP1B3 function and localization. S-palmitoylation (also known as S-acylation or palmitoylation) is a reversible post-translational modification that adds palmitic acid (C16:0) to cysteine residues and can influence a protein's function, localization, and protein-protein interactions. In this study, we investigated and characterized palmitoylation in OATP1B1 and OATP1B3. Using site-directed mutagenesis and acyl-resin-assisted capture assays, residue Cys24 was identified as the palmitoylation site for both …

Using Zebrafish To Investigate The Innate Immune Response To R132h Mutant Glioma, Mikaela L. Fairbanks

All NMU Master's Theses

Gliomas are the most commonly occurring brain tumor found in adults. The most dominant mutation found in glioma is in the isocitrate dehydrogenase 1 (IDH1) gene. IDH converts isocitrate into α-ketoglutarate (α-KG), but the mutated form of it will take α-KG and further convert it into D-2-hydroxyglutarate (D-2-HG). Mutated IDH1 glioma (mIDH1) produces a higher concentration of D-2-HG than the wild-type IDH1 glioblastoma (wtIDH1). These mIDH1 tumors tend to have a better prognosis, growing slower and having less inflammation than the wtIDH1 counterpart, potentially due to the increased D-2-HG. However, the effects of mIDH1 and D-2-HG on the innate immune …

Has Plant Domestication Compromised Plant Defensive Chemistry? Aphid Induced Stress In Tomatoes, Nhi Do, Satinderpal Kaur, Minxing Zhu, Esther N. Ngumbi

MICRO-CCS student projects

Tomato plants have natural defensive mechanisms.

Direct: Phenolics are secondary metabolites that can protect the plant by intoxicating the herbivores and/or producing strong repulsive odors.

Indirect: VOCs, Volatile Organic Chemicals, are gas phase signals that attract the predators of the attacking herbivore to the plant.

Domestication of plants may chemically alter these defenses by prioritizing fruit production over defensive traits.

We hypothesize that wild/ancient tomato plants would have a greater quantity of volatiles and increased concentration of leaf total phenolics compared to cultivated tomatoes during aphid herbivory.

How Does High-Oil Sorghum Change Potential Extracellular Enzyme Activity Across Soil Depth Profiles Under Drought Conditions?, Krystal Monique Role, Rounak Patra, Wendy Yang

MICRO-CCS student projects

Transgenic oil sorghum reallocates photosynthate-carbon (C) into vegetative lipids, accumulating nonstructural lipids in both shoot and root tissues. Altered plant C allocation and root lipid accumulation may shift root exudate chemistry, belowground C inputs, and microbial nutrient demand throughout the soil profile. While aboveground productivity in high-oil sorghum is well-characterized, its belowground impacts on soil microbial enzyme activity and exchangeable cation dynamics, especially across soil horizons under drought stress remain unknown.

Project objective was to find out how transgenic high oil sorghum (Tx-HO1) influences CNP acquiring extracellular enzyme activities and soil exchangeable cation dynamics across soil horizons under drought and …

Effects Of Varying Ph Levels On Prophenoloxidase Activity And Hemocyte Recruitment In Daphnia Dentifera, Yusra Siddiqi, Carla Caceres

MICRO-CCS student projects

Anthropogenic activities and natural processes are responsible for changing the pH of freshwaters which can impact aquatic life. D. dentifera is a keystone species found in midwestern lakes that is susceptible to a parasitic yeast called Australozyma monospora. A. monospora spores puncture the Daphnia gut into the hemolymph and begin using the host’s resources. Invertebrate immunity is under researched.

Research objective: How will different pH impact prophenoloxidase (proPO) activity and hemocyte recruitment in Daphnia dentifera?

Investigation Into Molecular Bases Of Pregnancy-Associated Malaria, Nicole Pozo

Biochemistry and Molecular Biology

Plasmodium falciparum causes the most severe and deadly form of malaria and remains a major global health problem, especially in sub-Saharan Africa (Milner, 2018). The parasite infects and multiplies inside red blood cells, leading to fever, anemia, organ damage, and death if untreated (Milner, 2018; Song et al., 2022). It is especially dangerous because it avoids the immune system by changing surface proteins called Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1), which are encoded by more than 60 var genes. By switching between these genes, the parasite hides from immune detection and creates repeated waves of infection (Deitsch & Dzikowski, …

Acute Intermittent Hypoxia And Acute Intermittent Hypercapnic Hypoxia Elicit Cortico-Diaphragmatic Plasticity In People With Chronic Spinal Cord Injury, Alysha Bogard, Michela Mir, Tommy Sutor, Jessica Dunn, Kathryn Cavka, Arian Vistamehr, Hannah Snyder, Joseph Welch, Jayakrishnan Nair, Gina Brunetti, Gordon Mitchell, Emily Fox

Department of Physical Therapy Faculty Papers

Respiratory impairment is a leading cause of morbidity and mortality after spinal cord injury (SCI), highlighting the need for interventions that improve breathing function. In people with SCI, acute intermittent hypoxia (AIH) elicits respiratory motor plasticity and improves inspiratory function. However, in uninjured people facilitation of corticospinal diaphragm motor evoked potential (MEP) amplitude occurs only when AIH is combined with mild hypercapnia (acute intermittent hypercapnic hypoxia; AIHH). It remains unclear whether AIHH similarly enhances diaphragm corticospinal excitability after SCI. We tested the hypothesis that AIHH increases diaphragm MEP amplitude and reduces MEP onset latency in individuals with chronic SCI, whereas …

Interpretable Machine Learning Of Plasma Proteomics Reveals Stage-Specific Signatures Across The Alzheimer's Disease Continuum, Hemshankar Laugi

2026 Spring Honors Capstones Projects

Alzheimer’s pathology begins years before clinical symptoms, starting early with amyloid-β accumulation, followed by tau deposition and neurodegeneration. Although existing tools, such as cerebrospinal fluid (CSF) screening and PET/MRI imaging, can accurately track disease progression, they are invasive, expensive, and not scalable for population-level screening. So, there is a growing interest in using blood-based plasma biomarkers as a scalable alternative. While recent studies demonstrate strong predictive performance with plasma biomarkers, most rely on a small set of canonical blood-based protein biomarkers such as amyloid-β, p-tau, and neurofilament light. These biomarkers primarily reflect downstream brain pathology and may fail to capture …

The Unexpected Role Of Conditionality In Shaping Relational Values: Insights From An Incentive-Based Conservation Program In Bolivia, Brooke Mcwherter, Will Munger, Zhao Ma, Claudia Radel, Laura Zanotti, Jonathan Bauchet, Ricardo Godoy

Department of Agricultural Economics Faculty Publications

As global change accelerates, Payments for Ecosystem Services (PES) programs have become increasingly important tools for addressing the interconnected challenges of land degradation, biodiversity loss, water scarcity, and climate change. PES programs provide incentives to individuals or communities, conditional on people adopting sustainable natural resource management practices to support or increase ecosystem service provisioning. Although conditionality is considered a “PES-defining feature,” little is known about how conditionality is perceived by community members and how such perceptions influence their participation in and experience with PES programs. To address this gap, we conducted an extensive qualitative study of Watershared, an incentive-based conservation …

These questions include the following: 1) Is a caloric surplus necessary for building skeletal muscle? 2) Is it possible to lose body mass or fat mass without caloric restriction? 3) Is intermittent fasting better than chronic caloric restriction for weight loss? 4) Are there sex differences in the response to fasting? 5) Can diet alone fulfill the macro and micronutrient needs of exercise-trained …

An Emergent Seafood Nationalism Takes Hold In The United States, Owen Temby

School of Earth, Environmental, & Marine Sciences Faculty Publications

This paper introduces the concept of ‘seafood nationalism’ to describe how, since 2024–2025, the United States increasingly uses tariffs, trade remedies, food safety enforcement and origin-based rules to favour American seafood over foreign products. Federal actions include Executive Order 14276, Restoring American Seafood Competitiveness, which directs agencies to address unfair trade practices, unsafe imports and to develop a coordinated seafood trade strategy. Additional measures include a tariff package imposing a 10% duty on nearly all seafood imports and 30% on seafood from China, as well as new anti-dumping and countervailing duty orders on warm-water shrimp. This paper presents Gulf …

Evaluation Of Loading, Release, And Bioavailability Of Resveratrol Encapsulated In Porous Starch, Yu-Yun Wang

Graduate Theses and Dissertations

Resveratrol (Res) is a polyphenolic compound found in grapes, red wine, and berries, with health benefits such as antioxidant, anti-inflammatory, and cardioprotective properties. The poor stability and bioaccessibility of Res after consumption by humans require the development of delivery systems. Among many delivery systems, porous starch (PS) is a safe, cost-effective, and high in adsorption capacity encapsulation material for drugs and bioactive compounds sensitive to environmental factors like light and heat. Porous rice, corn, and potato starch have different granule sizes, pore volumes, and surface areas. However, the impact of these encapsulation capabilities remains unclear among the three porous starches. …

The Role Of Speculators In The Agricultural Futures Market And Their Impact On Prices, Clement Asamoah

Graduate Theses and Dissertations

The study evaluates the impact of speculative activity on agricultural commodity returns, specifically in the corn, soybeans, rice, and oats markets. The study also analyzed the influence commodity returns have on speculative positions. Weekly data from the Commodity Futures Trading Commission were used as a proxy for speculative activity, and futures data were also retrieved from Barchart. Vector Autoregressive models and the Granger Causality tests were estimated to identify the relationships between returns and speculation. The paper found that speculative positions do not Granger-cause returns over the course of a week except for rice Tuesday results, which recorded a statistically …
