The Coral Microbiome Under Climate Change: Shifting Symbiotic Interactions, Katherine E. Parker, Kate M. Quigley

Biological Sciences Faculty Publications

Host–microbe symbioses are central to organismal health, yet these complex partnerships are often strongly shaped by the environment. Climate change is increasingly altering environmental conditions, disrupting the balance of host–microbe interactions and pushing them along a continuum from mutualism (both partners benefit) toward parasitism (one partner gains at the other’s expense). Reef-building corals provide a clear example of this vulnerability, as the coral holobiont, an ecological unit comprising diverse photosynthetic algal symbionts (Symbiodiniaceae) and other microbial partners, depends largely on these mutualistic interactions for nutrition, immunity, and stress tolerance. Increasingly, evidence suggests that under heat stress, the algal symbionts retain …

[Review Of The Book A Conspectus Of The North American Isoetaceae, By D. F. Brunton, J. T. Kartesz, M. Nishino, And P. C. Sokoloff]., Lytton John Musselman

Biological Sciences Faculty Publications

Isoetes (Isoetaceae; Lycopodiopsida; quillworts) constitutes a highly successful, cosmopolitan genus with over 200 species. Isoetes is derived from isos Greek for equal and eter for year, referring to the typically long persisting leaves of the sole genus in this ancient plant family. The leaves resemble a ‘quill-of-feather,’ hence the common name ‘Quillworts,’ wort, from old Germanic wurti, meaning plant. In large measure due to its simple form, inconspicuous appearance and negligible economic value, it represents one of the least studied and least collected of all North American genera. Isoetes constitutes a taxonomically enigmatic group with numerous polyploid species that arose …

Larval Genomics As A Viable, Fisheries-Independent Tool For Investigating Population Structure In Tropical Pacific Tunas, Jacob E. Jaskiel, Hannah E. Aichelman, Giulia Anderson, Louw Claassens, James E. Fifer, Christina M. Hernandez, Alexa K. Huzar, Joel K. Llopiz, Jan W. Witting, Sean P. Mullen, Randi D. Rotjan

Biological Sciences Faculty Publications

Understanding how dispersal, life history, and environmental variability shape genetic connectivity in the open ocean remains a central challenge in evolutionary biology. Highly migratory marine predators like tunas have traditionally been considered genetically homogeneous across ocean basins, yet emerging genomic evidence suggests that cryptic population structure can persist even in species with high gene flow and large effective population sizes. We used 2bRAD sequencing of 348 larval and subadult skipjack (Katsuwonus pelamis), yellowfin (Thunnus albacares), and bigeye tuna (T. obesus) collected from the central Pacific across 7 years of sampling to examine species boundaries, …

Broughton, Robert K. Cowen, Trika Gerard, Christina M. Hernández, John J. Hoey, Joel K. Llopiz, Molly E. Lutcavage, Estrella Malca, Debra L. Palka, Lourdes Vásquez-Yeomans, Harvey J. Walsh, C. Michelle Willis, Glenn A. Zapfe

Biological Sciences Faculty Publications

There is currently a lack of consensus on the spatial, seasonal and decadal-scale patterns of Atlantic bluefin tuna (Thunnus thynnus) spawning in the western Atlantic Ocean. We compiled ichthyoplankton and reproductive data to characterize bluefin spawning patterns and the uncertainty in these patterns. Ichthyoplankton data indicates that bluefin spawn in the Gulf of America/Gulf of Mexico, northwest Caribbean Sea, north of the Bahamas, along the inshore edge of the Florida Current off the Carolinas and in the western Slope Sea. Reproductive studies identified these same spawning areas, as well as the Windward Passage and waters east of the …

Land Use Influences Dissolved Organic Matter Composition In The U.S. Coastal Critical Zone Network, Aleksandar I. Goranov, Elizabeth V. Whitney, Brian R. Moyer, Katherine L. Tully, Patrick G. Hatcher, Yu-Ping Chhin

Chemistry & Biochemistry Faculty Publications

Coastal watersheds are highly productive biogeochemical systems supporting robust coastal fisheries and contributing significantly to the marine gross primary production flux. These ecosystems are comprised of civil infrastructure, farms, forests, and marshes, and their diversity is reflected in the quantity and quality of dissolved organic matter (DOM). Here, we assess the role of farming in influencing DOM from surface waters of six coastal tidal creeks adjacent to forest and farm sites in the US Critical Zone Network. Molecular fingerprinting using electrospray ionization - Fourier transform - ion cyclotron resonance - mass spectrometry revealed that farm-influenced DOM was enriched in nitrogen-, …

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Manicured, monoculture lawns often dominate private land in urban areas for aesthetic organization. Colonialist roots are embedded in the history of turfgrass lawns and white-picket fences intended to suppress Indigenous knowledge and ways of caring for the diverse land around us. Private land misuse and homogenous lawns are not limited to the United States; the modern lawn contributes to biodiversity loss on a global scale. Humans are concentrated in cities across the world, and urban areas are known to have negative implications for wildlife and habitat, human health, and sustainable resource use. Management of private land in urban settings is …

Assessing Aerobic And Anaerobic Exercise As Therapies For Sarcopenia, Ella B. Farrer

Student Research Poster Presentations 2026

Sarcopenia is an age-related condition represented by progressive changes in muscle physiology that results in the loss of muscle mass and strength. The onset varies amongst individuals and can be influenced by various factors. On the cellular level, mitochondrial dysfunction and disruptions at neuromuscular junctions have been associated with the progression of sarcopenia. The condition ultimately reduces mobility, increases mortality, and hinders quality of life in older populations, necessitating an understanding of effective therapies.

Exercise was linked to symptom reduction of sarcopenia. Evidence indicated aerobic exercise and anaerobic exercise influence distinct molecular pathways involved in muscle physiology. Literature assessed the …

Microplastics Effect On Gut Microbiota, Victoria Rae Pellew

Student Research Poster Presentations 2026

Microplastics Effect on Gut Microbiota 

PELLEW, V, Misericordia University, 301 Lake Street, Dallas, PA, United States, 18612

Microplastics (MPs) are small plastic particles less than 5mm in size that are present throughout the environment and are commonly found in both food and water, making human exposure unavoidable. Ingestion occurs through consuming contaminated food, inhalation by breathing airborne particles, and dermal contact via phone cases or skin care products. Once absorbed into the body, MPs may influence human health by altering the gut microbiome.

Results from human fecal studies and in vitro models have shown that MPs can alter pathways associated …

Methods: Exercise protocols consisted of 2-minute work intervals interspersed with 1-minute recovery intervals (20W), HI consisted of 5 intervals performed at a workload corresponding to 140% of ventilatory threshold intensity and LI and LI-BFR consisted of 10 intervals performed at 70% of ventilatory threshold. BFR cuffs were inflated to 80% of limb occlusion pressure during each work interval and deflated during each recovery. Following each exercise protocol subjects rested for three hours, …

Variable Infections But No Evidence Of Immune Priming In Bumble Bee Hosts Against Novel Exposure To A Honey Bee Virus, Austin C. Calhoun, Ben M. Sadd

Faculty Publications – Biological Sciences

Ongoing global change presents novel challenges to species persistence, including heightened emerging infectious disease (EID) exposure. While invertebrates lack vertebrate acquired immunity, many species exhibit “immune priming” with enhanced protection to repeated pathogen exposures. This phenomenon could be critical for species of conservation concern, such as for wild bumble bees, where EID risk is amplified through contact with managed bee pollinators. We investigate the potential for immune priming against the honey bee-derived Israeli Acute Paralysis Virus (IAPV) in Bombus impatiens bumble bees. We test the hypothesis that prior pathogen-associated exposure affords greater resistance and tolerance upon secondary pathogen exposure, due …

Managing Multi-Drug Resistance: An Evolutionary Game Theory And Optimal Control Approach, Shukhrat Nasrulloev

Theses and Dissertations

Multi-drug resistance is an evolutionary process in which treatment eliminates sensitive cells, allowing resistant clones to dominate. This thesis investigates this process using a framework integrating population dynamics, evolutionary game theory, and optimal control theory. We develop a two-population logistic growth model describing competition between drug-sensitive and drug-resistant cells under treatment, construct dose-dependent payoff matrices and replicator dynamics to characterize evolutionary competition, and derive a critical drug level D_crit = (r_S - rR)/(dS - d_R) at which resistant cells gain a fitness advantage. An optimal control problem is formulated via Pontryagin's Maximum Principle to identify schedules …

Increasing Temperatures And Heatwave Durations Negatively Affect The Performance Of A Dietary Generalist, Kailey G. Hicks, Claire Guzinski, Mariana Abarca, Mayra C. Vidal, Audrey M. Mitchell, Dhaval K. Vyas, Shannon M. Murphy

Biological Sciences: Faculty Publications

Climate variability has increased in recent decades, and this trend is predicted to continue. Globally, there is a rise in extreme temperatures, such as heatwaves, which are strengthening in both intensity and frequency. As ectotherms, insects are especially affected by temperature variation. Insects are the most speciose group of animals and important members of most terrestrial ecosystems, providing critical ecosystem services. Most studies of global change have investigated only a single stressor, yet insects rarely experience one stressor at a time. Two stressors that co-occur are heatwaves and warming temperature regimes; thus, is it important that we study their interaction …

Occupational Therapy Doctorate Capstone Posters

This capstone project focused on education and advocacy. The aim of my capstone project was to provide education to parents of eastern Kentucky (KY) about what Occupational Therapy (OT) can address with infants aged 0-18 months. I saw a gap in knowledge in the eastern KY community about what OT could do for infants and wanted to address this. Through my research, consultation with my mentors, and collaboration with the occupational therapists at my site (BPT) I discerned 14 areas of development and/or common reasons of needed referral for OT services by this age group. These educational materials aimed to …

Investigation Of Diverse Carf Effectors In Type Iii Crispr - Cas Immunity, Gianna Marie Stella

Student Theses and Dissertations

All domains of life can be infected by viruses. The simplest forms of life, bacteria, are outnumbered by their viruses, called bacteriophage or phage, by 10 to 1. It is estimated there are more phages on Earth than stars in the sky. Phage act as parasites to bacteria by ejecting their DNA into the cell and hijacking host machinery to produce more viral particles. Once new phage particles are assembled inside the cell, the bacterium will lyse, leading to not only to the death of the bacterium but also the proliferation of more viruses. Bacteria encode a range of strategies …

Agricultural Productivity Under Energy Development: Insights From California, Wai Yan Siu, Sherzod B. Akhundjanov

ODU Articles

This paper examines how agricultural productivity patterns in Kern County, California, a leading region for both agricultural production and oil and gas development, co-vary with the spatial and temporal expansion of hydraulic fracturing and associated energy infrastructure. Using parcel- and county-level analyses, we characterize how agricultural productivity differs across proximity to energy development and across spatial scales. The results reveal spatially heterogeneous and scale-dependent patterns: parcel-level evidence indicates lower Enhanced Vegetation Index-based vegetation productivity within the 20-mile proximity zone around fracking wells, while county-level results show heterogeneous crop-specific yield changes during the post-expansion period. Together, these findings highlight the importance …

Cover Crop Effects On Soil Porewater Nutrients And Hydrothermal Properties, Md Mahadi Hasan

Theses and Dissertations

Adoption of winter cover crops in the U.S. Midwest may reduce nitrogen (N) and phosphorus (P) leaching from soils, potentially shrinking the hypoxic zone by limiting nutrient runoff into the Gulf of Mexico. To evaluate the impact of selected winter cover crops on soil porewater N and P concentration, a field study was conducted at the Illinois State University Research Farm (ISURF) and the Western Illinois University Research Farm (WIURF). The experimental design was a block experiment with four replications.  Cover crop treatments included a winter fallow, wild pennycress (WPC), golden pennycress (GPC), cereal rye (CR), annual ryegrass (AR), and …

The Impacts Of Wing-Flashing By Northern Mockingbirds On Foraging, Parental Care, And Reproductive Success, Anna Reece Starman

Undergraduate Research Awards

Foraging efficiency may be enhanced by flashing patches of white wing and tail feathers and has been documented in several avian species. Northern Mockingbirds (Mimus polyglottos, NOMO) exhibit this “wing-flashing” (WF) behavior while foraging, during displays, and in response to predators. In NOMOs, WF has been hypothesized to increase foraging success, but previous findings are inconclusive. To further investigate the biological role(s) of WF behavior in NOMOs, the ventral surface of white primary feathers of male NOMOs were artificially darkened and the foraging and provisioning rates of undarkened (control) males and their mates were compared. While foraging, undarkened males performed …

Granulomatous Cellular Signatures In Nontuberculous And Tuberculous Mycobacterial Infections, Brianna M. Doratt, Ethan G. Napier, Mahdi Eskandarian Boroujeni, Sarah Douglas, Michael H. Davies, Luiz Bermudez, Eliot Spindel, Erin F. Mccaffrey, Ilhem Messaoudi

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Mycobacterium tuberculosis (Mtb) and nontuberculous mycobacteria (NTM) are acid-fast bacilli that trigger granuloma formation, a hallmark immune response aimed at containing infection. While the biology of Mtb granulomas has been widely investigated, far less is known about granulomas caused by NTM infection, despite the increasing prevalence and clinical challenge of NTM cases worldwide. Because granulomas influence infection control, pathology, and treatment response, understanding their cellular organization and signaling is critical to improving therapeutic strategies. Therefore, we characterized granulomas formed following infection of rhesus macaques with Mycobacterium avium subsp. hominissuis (MAH) and compared them to granulomas from cynomolgus macaques infected with …

Glycoprotein-Specific Transcriptional Response Contributes To Differential Vaccine Protection Against Lethal Ebola Virus Infection, Sheridan B. Wagner, Delphine C. Malherbe, Ethan G. Napier, Andrea Marzi, Ilhem Messaoudi

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Since the West African Ebola virus (EBOV) epidemic in 2014-2016, recurrent outbreaks of the EBOV-Makona variant have been driven by recrudescence and human-to-human transmission emphasizing the need for effective vaccination strategies. A live-attenuated recombinant vesicular stomatitis virus (VSV)-based vaccine expressing the EBOV-Kikwit variant glycoprotein (VSV-Kik) received FDA approval in December 2019 and provides complete, rapid protection against EBOV-Makona as early as 7 days post-vaccination (DPV). During the 2018-2020 Ebola outbreak, the VSV-Kik vaccine, known as ERVEBO, was administered to lower-risk individuals at a 5-fold dose reduction of the standard 2 × 10 ⁷ PFU to provide broader population protection. Identification …

False-Positive Detections In Avian Auditory Surveys: Effects Of Song Number And Directionality In A Calibration-Based Immersive Sound Environment, Katia Elena Chavez

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Detection-based surveys are widely conducted to monitor wildlife populations and provide data for estimating density and abundance. Avian count surveys are especially common because birds respond quickly to habitat degradation and restoration, making them effective indicator species. However, these detection-based surveys rely heavily on human observers and are prone to errors. If left unaddressed, these errors can bias estimates of species occurrence, and abundance, leading to misleading ecological inferences and management decisions. False-positive errors have received limited attention, in part because they are difficult to identify without independent confirmation of true species. To investigate false-positive rates in a controlled setting, …

2026 Honors Symposium

Physical activity in children is significant for all aspects of their development, including cognitive, physical, emotional, and social aspects. Recess is important for children to be given a designated time to exercise and get physical activity. For some children, recess is the only time they get to exercise in a day. This study aims to examine differences in activity levels between genders at Leverett Elementary School. It is important to know if there is a disparity between boys and girls at recess, so that educators, parents, and administrators can work to bridge any gaps and ensure that all kids are …

Pain And Pace: Investigating Gait Velocity In Individuals With Cancer, Melaina E. Taylor

2026 Honors Symposium

Background: Cancer remains the second leading cause of death worldwide, with incidence rates continuing to rise. Pain, a hallmark symptom of many cancers, is caused by both the progression of disease and treatments. Gait, the way in which someone walks, is now dubbed the “6th vital sign” for its strong relationship with functional status, longevity, and survival. Specifically, gait velocity is a key metric for gait, with previous studies in cancer free adults showing increased pain associated with a decreased gait velocity. The relationship between gait velocity and pain has not yet been explored in individuals with cancer. Purpose: The …

Inpatient Stroke Quality Improvement, Briyawna N. Wyatt

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive

Inpatient nursing documentation for stroke care is essential for meeting quality metrics, maintaining continuity, and supporting timely decisions. Gaps can lead to inconsistent care, metric failures, and reduced staff confidence. This quality improvement initiative aimed to improve metric compliance, documentation consistency, and nursing knowledge and satisfaction. A three-part intervention included targeted education, a standardized documentation verification form, and ongoing feedback from stroke champions. Outcomes measured were metric compliance, knowledge (pre/posttests), documentation completeness (Venous Thromboembolism (VTE), education, Modified Rankin Scale), and staff satisfaction. Results showed significant improvement in nursing knowledge (p < .005), reduced metric fallouts, and better documentation across all indicators. Staff satisfaction increased by about 20%. Overall, combining education, standardized tools, and continuous feedback improved documentation practices, enhanced compliance with stroke metrics, and increased nursing knowledge and satisfaction, supporting better care processes and patient outcomes.
