Climate Change Effects On Biomass And Greenhouse Gas Emissions Are Ameliorated By Nontoxic Endophytes In Southeastern Usa Transition Zone Tall Fescue Pastures, Rebecca Kay Mcgrail, Jonathan D. Moore, A. Elizabeth Carlisle, Jim A. Nelson, Rebecca L. Mcculley

Plant and Soil Sciences Faculty Publications

Background: The plant–microbe interaction between tall fescue and its endophyte Epichloë coenophiala can affect ecosystem responses to changing rainfall patterns and increasing temperatures. Endophyte-infected (E+) stands often exhibit improved stress tolerance and differing soil greenhouse gas (GHG) emissions compared to endophyte-free (E−) stands. However, it is unknown if mammalian nontoxic endophyte (NTE) strains introduced into some tall fescue cultivars confer differing stress tolerances or reduce soil GHG emissions.

Methods: We quantified the impact of fescue-NTE symbioses in Jesup and Texoma on biomass and GHG emissions in response to increased temperature (+3°C) and altered precipitation (50% lengthened interval between events) using …

Dosage Sensitivity And The Evolution Of Dosage Compensation: Tests Of The Insensitive Sex Chromosome Hypothesis In Flour Beetles, Shana Pau

Biology Dissertations

Sex chromosome evolution generates imbalances in gene dosage that can disrupt gene expression and organismal function. These imbalances are often resolved through dosage compensation mechanisms, yet the factors that drive the emergence and diversity of these systems remain poorly understood. This dissertation addresses a central question in evolutionary genomics: what governs the evolution of dosage compensation?

Focusing on dosage sensitivity as a potential driver, I evaluate the Insensitive Sex Chromosome Hypothesis (ISCH), which predicts that chromosome-wide compensation is more likely to evolve in genomic contexts that are not depleted of dosage-sensitive genes. Using flour beetles (Tribolium spp.) as a …

Separation Of Trichothecene Mycotoxins In A Matrix Of Hemp (Cannabis Sativa L.) Seed, And Quantification Of Deoxynivalenol In Hemp Grain Infected With Fusarium Graminearum, Isabelle A. Kagan, Magdalena Ricciardi, Henry S. Smith, Rachel R. Schendel, Robert Pearce, Nicole Gauthier

Plant and Soil Sciences Faculty Publications

Background: Fusarium graminearum, one of the causal agents of ear rot in maize and head blight of cereal grains, also infects hemp (Cannabis sativa L. containing a maximum of 0.3% tetrahydrocannabinol or THC). This fungal pathogen produces trichothecene mycotoxins when it infects maize and cereal grains, but little is known about its production of mycotoxins in hemp. A method was developed to separate mycotoxins deoxynivalenol (DON), 15-acetyldeoxynivalenol (15-ADON), and 3-acetyldeoxynivalenol (3-ADON) in commercial hemp seed and grain (harvested tissue), using high-performance liquid chromatography (HPLC) with ultraviolet detection. Results: In HPLC analysis of commercial hemp seed, DON was separated from matrix …

Disrupted Circadian Rhythms Affect Hallmark Pathologies In Alzheimer’S Disease-Related Mouse Models, Valeria Buzinova

Theses and Dissertations--Molecular and Cellular Biochemistry

Alzheimer’s Disease (AD) is a complex neurodegenerative disease with two hallmark pathologies: extracellular amyloid-b (Ab) and intracellular neurofibrillary tangles (NFTs). Ab is proteolytically processed from amyloid precursor protein (APP) by b-secretase and g-secretase as a monomeric peptide prone to aggregation. Eventually, the aggregate-prone monomers will form dense plaques that are difficult to break down and remove. These plaques begin to deposit into the cortex decades prior to the formation of NFTs and the onset of cognitive decline. NFTs are comprised of hyper-phosphorylated tau. Tau is a protein that serves to promote and stabilize the formation of microtubules. The formation of …

Characterizing The Human Metapneumovirus Matrix Protein And Its Role In Infection, Chase J. Heim

Theses and Dissertations--Molecular and Cellular Biochemistry

Human metapneumovirus (HMPV) causes severe respiratory tract infections in all cohorts, but especially in vulnerable groups such as children, older adults, and the immunocompromised. The matrix (M) protein of HMPV, like the M proteins of other members of the Mononegavirales order, is involved in virus assembly and budding. However, other functions of the HMPV M protein have yet to be elucidated. To investigate these various functions of the M protein, we used a peptide-conjugated phosphorodiamidate morpholino oligomer (PPMO) antisense agent designed to block translation of the M gene to reduce M expression during infection. Treatment with varying concentrations of an …

From Chaos To Clockwork: Investigating The Role Of Circadian Genes In Metabolic Development Of 2nd And 3rd Instar Drosophila Larvae, Elliott Ruegsegger

2026 Research Poster Competition

Connecting deficits in circadian rhythm machinery to the severity of other health conditions is a common task that chronobiology, the study of physiological rhythms, undertakes. Disruptions to circadian rhythms and sleep are linked to increased risk of developing multiple different diseases, including Alzheimer’s Disease and obesity. Circadian rhythms are expressed at the molecular level through rhythmic variations in the concentration of specific proteins. While the central clock genes that produce these proteins, such as period and timeless, are evolutionarily conserved across the animal kingdom, not much is known about the consequences of disruptions in circadian rhythm machinery during early development, …

Moving Towards Defining The Evolutionarily Ancient Role Of Notch Signaling In Animals., Paige Norris

2026 Research Poster Competition

The notch signaling pathway is deeply conserved across animals from humans to sponges. It functions through direct cell-to-cell communication, where ligand binding triggers the cleavage of the Notch receptor’s intracellular domain (NICD), which then translocates to the nucleus to regulate transcription. In bilaterian lineages—animals with bilateral symmetry— Notch signaling is known to regulate binary cell fate decisions in diverse contexts ranging from neurogenesis to cancer. However, the functions of Notch signaling in early-branching animals, including cnidarians (e.g. jellyfish, corals and sea anemones), are still not fully understood; consequently, evolutionarily ancient roles of Notch remain ill-defined. To address this fundamental knowledge …

Investigating Pituitary Specific Transcription Factor-1 (Pit-1) In Neuronal Development In The Sea Anemone Cnidarian Nematostella Vectensis, Emily Ye

2026 Research Poster Competition

In bilaterians — animals with bilateral symmetry, like vertebrates and insects — the pituitary specific transcription factor-1 (pit-1) is essential for regulating growth hormone and prolactin expression in the pituitary gland. However, in non-bilaterians, the ancestral function of pit-1 remains unknown. Cnidarians, such as the sea anemone Nematostella vectensis, form a sister group to bilaterians and lack a pituitary gland, making them a powerful model for investigating the early evolutionary role of conserved developmental genes, like pit-1.Using CRISPR-mediated gene editing, pit-1 knockout mutants — anemones without the pit-1 gene — were generated, and their transcriptomic, cellular, and behavioral phenotypes were …

Effect Of Organic Vs Inorganic Zinc Sources In Beef Cattle Diets During Gestation On Calf Immune Function And Colostrum Quality, Naija Sharpley

2026 Research Poster Competition

The objective of this study is to determine the effect of zinc supplementation in cattle feed on beef cattle during gestation and the influences of the trace mineral zinc on colostrum and calf immunocompetence measuring immunoglobulin concentrations and body weight. Cow-calf systems rely on the effectiveness and consistency of their nutritional intake. Beef cattle are fed forages and grain alongside specific minerals and supplements to meet nutritional requirements. The effectiveness of these trace minerals added to the diet helps to ensure that the animal gets the most out of its feed and the producer gets the most out of the …

Investigating The Potential Role Of Horse Flies (Diptera: Tabanidae) In The Mechanical Transmission Of Anaplasma Marginale And Theileria Orientalis To Cattle In Northwest Arkansas, Catherine Harrison

2026 Research Poster Competition

The cattle industry in Arkansas plays a significant role in the state’s agricultural economy; however, two emerging infectious diseases pose a threat to cattle health, producer livelihood, and animal welfare. The two diseases, anaplasmosis and theileriosis, are caused by organisms that enter the host’s bloodstream and infect red blood cells, leading to destruction of said cells. The shared symptoms of both diseases are fever, weakness, anemia (low red blood cell count), reduced productivity, weight loss, and possibly death. An important difference between symptoms is that, unlike anaplasmosis, theileriosis can cause abortion in cattle. Both diseases are known to spread through …

Differences In Cytokine Mrna Expression At The Site Of Primary And Secondary Vaccinations With Herpesvirus Of Turkeys (Hvt) In Egg-Type Chickens., Allie Bowerman

2026 Research Poster Competition

Marek’s disease, a lymphoma causing virus, remains a major concern in poultry production systems. Although vaccination with live herpesvirus of turkeys (HVT) is crucial for controlling this disease, information on how the vaccine drives local/tissue immune responses that lead to protective immunity is limited. Using the growing feather (GF) in vivo bioassay, we assessed local cytokine mRNA expression following primary and booster intradermal (i.d.) HVT vaccinations in egg-type chickens. For this, six 9-week-old and six 19-week-old Light-brown Leghorn (LBL) pullets were i.d. injected into the pulp of growing feathers (GF; 10 µL/GF; 16 GFs/bird) with a primary (V1) or secondary …

Hybridized-Highway Infrastructures, Will Sutton

2026 Research Poster Competition

This research explores highways and their evolving functions through hybrid programming, from the modern era to the present day. As early as 1916, the federal government began funding state construction of the National Highway System. From this point onward, by design, highways became redundant and homogenized networks of automobile movement, crystallizing their function. Despite this, there are global examples of architecturally utilizing space within, above, or below highway infrastructures that hybridize their function beyond vehicular movement. I am currently studying hybridized-highway infrastructures through a literature review that examines them through the lenses of underutilized space associated with highways, the roles …

"Leafing" Through The Chinese Opera: Phytopoetics In The Peony Pavilion, Madison Bussell Escoto

2026 Research Poster Competition

Ornamental flowering plants have been instrumental symbols in literature across all times and cultures. I’m examining why flowers are such perceptual stimulants, sexual symbols, and literary agents. Through the lens of Joela Jacob’s term “phytopoetics,” which describes the impact of plant life on the human imagination and culture; botany; and literary scholarship, I will look closely at this phenomenon in The Peony Pavilion, a Chinese opera from 1598 which features the first recognized complex and convincing female protagonist in world literature. Exploring “the garden” as a place, I will present the embodied, sensory, and relational elements of the human-flower relationship …

Blood Flow Regulates Metabolism In Hematopoietic Development, Pamela L Wenzel

Faculty, Staff and Student Publications

Blood flow modifies oxygen availability and biomechanical forces within the vasculature of the embryo as the hematopoietic system develops. The aorta-gonad-mesonephros (AGM) envelops the largest artery in the body and is a critical site for the emergence of hematopoietic stem cells (HSCs). Herein, I discuss the role of hypoxia-inducible factors (HIFs) and force as determinants of metabolism and fate determination. To address the effects of blood flow on hematopoietic development, I employ mouse embryo models and biomimetic culture. Real-time cell metabolic analyses show that oxygen consumption rates (OCR) and extracellular acidification rates (ECAR) are altered by flow in cultures of …

Planning For Equitable And Transparent Outdoor Recreation Permitting Within The James River Park System, Sarah J. Girard

Master of Urban and Regional Planning Capstone Projects

The City of Richmond has experienced an imbalance within the current special event permitting process for the Department of Parks, Recreation, and Community Facilities. Park users are not reporting sizeable events being held within the James River Park System, which has caused concern pertaining to environmental and societal impacts. The current permitting process lacks depth and clarity that could be solved by beginning with expanding park user data. This gap of data is the missing piece for the City to be able to make informed future decisions based on a wide array of stakeholder input and tangible visitor use metrics.

Substance Use Behaviors And Treatment Engagement In Individuals With Severe Psychopathology With And Without Comorbid Obesity, Rachel M. Madera-Arnold

Theses and Dissertations

Research has found significantly higher rates of both substance use and obesity among individuals with SMI compared to population samples which in turn can lead to worsening health outcomes. Despite this, there is limited research on the co-occurrence of obesity, substance use, and SMI and how these conditions may interact to affect patient outcomes. In addition, there are many gaps in the research regarding the relationship between substance use and body weight, appetite and/or eating behaviors. This study conducted a secondary analysis of the NSDUH 2021 survey that characterized substance use and disorders among individuals who had severe psychopathology, examined …

Environmental Monitoring In Shallow Lakes: Public Health Threats In Urban Waters, Kyleigh E. Johnson

Theses and Dissertations

Lakes are an integral part of urban and suburban communities, providing ecological, recreational, and public health benefits. Many of these lakes are located in densely populated areas and are subject to urban influences on water quality. Algal toxins and Escherichia coli are two common recreational concerns. Algal toxins come from harmful algal blooms that are influenced by nutrient availability and temperature, while bacteria are often introduced through run-off and animal waste. Sampling every 3-4 weeks from May-October 2025 allowed for the assessment of seasonal patterns and site-specific differences across nine lakes in the Richmond area. The highest bacterial concentrations appeared …

RNA therapeutics are a rising drug category with potential use for a range of conditions encompassing infectious diseases to therapies for cancer, diseases, and genetic disorders. RNA-lipid nanoparticles (RNA-LNPs) are the prominent delivery method for these therapeutics approved products include mRNA vaccines and polyneuropathy treatments. The emergency use authorizations and orphan drug status of current RNA-LNP drugs has allowed approval without finalization of the regulatory analytical procedures for quality monitoring. The objective of the study was to develop an LC-MS assay to simultaneously measure identity and concentration of two therapeutically relevant intact RNA constructs extracted from RNA-LNPs to enhance quality …

Musings Of A Dyke: Reimagining A Lesbian Past To Support A Lesbian Future, Tori Mitchell

Theses and Dissertations

This thesis interrogates the heterosexist bias inherent in historical narratives by recontextualizing myth, biblical accounts, folklore, and art history through a dedicated lesbian lens. Utilizing oil painting as my primary medium,  I construct a metafictional world–a pseudo-historical space where the foundational assumption is that every figure is a lesbian until proven otherwise. This inversion serves as a direct counter-narrative to the default lens of cis heteronormativity typically applied to the past. Within this world, I “lesbianize” the traditional icons of Western culture: the heroes, the symbols, and the deities.

My practice navigates the tension between reinvention and extinction, viewing both …
