Management Of The Invasive Honeysuckle (Lonicera Maackii), Mesa Grine, Daniel Hazelett, Cassie Healy, Padma Deepika Kandregula
Runkle Woods Symposia
This presentation addresses the ecological threat posed by invasive honeysuckle in the Runkle Woods on Wright State's campus. Originally from Europe and Asia, honeysuckle aggressively outcompetes native flora due to its rapid growth, shade tolerance, and allelopathic properties. The students observed widespread honeysuckle in both new and old growth forest areas, with greater density in younger regions. Ineffective control methods—such as cutting without herbicide—often worsen infestations. Drawing on a regional study, the students propose a targeted management plan involving cutting and herbicide application, stem injection for larger plants, and reintroducing native species like spicebush. Their strategy aims to reduce honeysuckle …

Old Growth In The Runkle Woods, Madeline Greene, Lindsay Smith, Matt Tyren, Leif Walters
Runkle Woods Symposia
In this conservation proposal, Wright State students focus on protecting the old growth areas of Runkle Woods—a rare and ecologically significant habitat in the Eastern United States, where only about 1% of such forests remain. Home to trees over 200 years old and critical species like endangered bats and white oaks, this 100-acre area faces threats from invasive species, deer overpopulation, littering, and urban runoff. Currently, only 15 acres are legally protected. The students propose expanding the easement, involving experts and graduate students in ongoing research and stewardship, and increasing public engagement through educational walks and increased and updated signage. …
Up In Smoke: Indigenous Techniques To Combat Climate Change And Increase Biodiversity, Brad Kerry
Up In Smoke: Indigenous Techniques To Combat Climate Change And Increase Biodiversity, Brad Kerry
Runkle Woods Symposia
Brad Kerry explores how Indigenous land management practices—particularly the use of prescribed fire—can be reintroduced to restore the Runkle Woods to its pre-colonial ecological state. Drawing on archaeological evidence, historical tree surveys, and ecological data, the presentation highlights how periodic, low-intensity fires historically maintained the forest’s biodiversity, promoted fire-adapted species like oak and hickory, and suppressed invasive plants. Kerry advocates for carefully planned, small-scale burns to combat "mesophication"—a shift toward shade-tolerant, fire-averse species—while increasing forest resilience to drought, invasive species, and climate change. The presentation underscores the ecological benefits of fire and outlines practical considerations for reintroducing controlled burns as …

In Vitro Investigation Of The Potential Therapeutic Implications Of Safranal On Gastric Cancer, Aisha Juma Al Otaibi
In Vitro Investigation Of The Potential Therapeutic Implications Of Safranal On Gastric Cancer, Aisha Juma Al Otaibi
Thesis/ Dissertation Defenses
Despite the fact that gastric cancer patients are indispensable to conventional radiation and chemotherapy, the detrimental side effects of those approaches prompt cancer research to seek new integrative treatments. In this respect, safranal (SAF) stands out as a complementary phytotherapeutic drug with exceptional anticancer properties. Concurring studies have shown that SAF is negatively associated with several cancer types, yet its potential therapeutic impact on gastric cancer remains vastly obscure. Thus, this dissertation sought to investigate SAF's prospective tumoricidal ability and its underlying mechanisms of action on gastric cancer in vitro. Herein, the study evaluated the cytotoxicity of SAF on human …
Human Impacts On Mammal Diversity From The Pleistocene To The Present, Carson P. Hedberg
Human Impacts On Mammal Diversity From The Pleistocene To The Present, Carson P. Hedberg
Biology ETDs
Humans have fundamentally altered the planet’s biodiversity. It is critical to characterize these changes, but also to understand how they impact the structure and function of modern ecosystems. This dissertation investigates how anthropogenically mediated species losses and/or introductions influence ecological function and community structure in mammals across multiple temporal and spatial scales. We found that selective loss of large-bodied mammals over the Late Quaternary has led to severe losses in functional diversity in modern ecosystems, suggesting megafaunal mammals contribute distinct ecological functions. These changes to mammal diversity and distribution over millennia have altered both global patterns in functional diversity and …

Going Against The Family: Perturbation Of A Greenbeard Pathway Leads To Falsebeard Cheating, Peter Lehmann, Mariko Katoh-Kurasawa, Peter Kundert, Gad Shaulsky
Faculty, Staff and Students Publications
Greenbeards facilitate cooperation by encoding a perceptible signal, the ability to detect it, and a tendency to help others that display it. Falsebeards are hypothetical cheaters that display the signal without being altruistic. Despite many examples of greenbeards, evidence for falsebeards is scarce. The Dictyostelium discoideum tgrB1-tgrC1 allorecognition pathway encodes a greenbeard. It allows development, which yields fruiting bodies with altruistic stalks that increase spore dispersal. Here we show that cells lacking rapgapB, a tgrB1-tgrC1 signaling element, cheat by avoiding the stalk fate and generating more spores in chimeras than in pure populations. rapgapB– cells cheat only on …

Best Practices For The Naming Of Species, Luis A. Ruedas, Ryan W. Norris, Robert M. Timm
Best Practices For The Naming Of Species, Luis A. Ruedas, Ryan W. Norris, Robert M. Timm
Biology Faculty Publications and Presentations
The process of describing a species has evolved considerably since the modern age of taxonomy was initiated with the publication of the 10th edition of Linnaeus’ Systema Naturæ in 1758. Nevertheless, the basic unit of the taxonomic framework remains the species group (species and subspecies). As a result, it is incumbent upon individuals undertaking species-group descriptions to strive for the highest standards, just as it is for reviewers and editors to hold authors to those same standards. The clear and mounting biodiversity crisis, the increasing proliferation of journals, the multiplication of journals publishing only in electronic format, the decline in …

The Mojave poppy bee, Perdita meconis Griswold, is a small fairy bee endemic to the eastern Mojave Desert, known to be associated with the Las Vegas Bearpoppy, Arctomecon californica. Because of the reported decline in populations of P. meconis, it has been targeted for protection under the Endangered Species Act. Here, we present the results of a 3-year study investigating the current distribution and floral preferences of P. meconis in Clark County, Nevada. We found that populations of P. meconis fluctuated dramatically from 2020 to 2022. This area experienced extreme drought conditions during these years, which consequentially affected …
Exploring The Role Of Tissue-Resident T Cells In Neurotropic Viral Infections And Opioid-Induced Immune Disorders During Exposure And Withdrawal, Shenjian Ai
Arts & Sciences Graduate Student Theses and Dissertations
Tissue-resident T cells play a crucial role in the immune response to neurotropic viral infections and opioid-induced immune disorders. Understanding the roles of tissue-resident T cells in these contexts is essential for developing therapeutic strategies to mitigate their detrimental effects while enhancing their protective functions. The chemokine receptor CXCR6 and its ligand CXCL16 are critical in maintaining the population of tissue-resident T cells in the CNS. CXCR6 is expressed on CD8 T cells that persist in the CNS after recovery from West Nile virus infection. Research has shown that CXCL16, produced by microglia and other myeloid cells, binds to CXCR6 …

Karbala International Journal of Modern Science
Identifying microorganism species, such as Lactobacillus, is essential in ensuring the food products' quality and safety. Traditional laboratory practice requires expert knowledge and experience, but the method is expensive and time-consuming due to complex sample preparation. Faster, more accurate, and cheaper computational methods, such as transfer learning technology, are needed for the Lactobacillus species classification. The technique has been effective in a variety of image recognition contexts. Deep learning architecture can also be applied as an innovative strategy for digital image-based identification. Therefore, this research aims to compare several deep-learning architectures in classifying bacterial strains of Lactobacillus. The four architectures …

Role Of B Cell Mediated Immune Responses During Skin ‘Atopic Dermatitis’ Disease, Hidaya Mohammed Abdul Kader
Thesis/ Dissertation Defenses
Atopic dermatitis (AD) is the most prevalent non-infectious skin allergies with approximately 10-30% adults and 40% children being affected worldwide. It is clinically characterized by eczema tic lesions and elevated IgE levels and is a multifactorial disease that is heterogeneous in nature. AD results in a dominant Th2 polarized immune response. Until date, there is no cure for this disease. B cells are key players of humoral immune responses and contribute significantly to allergic responses through IgE secretion. However, recently a subset of B cells termed regulatory B cells (Bregs) were discovered that were shown to have a protective role …

Assessing The Impact Of Irrigation Water And Soil Salinity On Date Palm And Desert Soil Associated Microbiota, Subha Chandran
Thesis/ Dissertation Defenses
Soil salinization poses a critical challenge in arid and semi-arid regions, where water scarcity is exacerbated by climate change and unsustainable agricultural practices. This phenomenon not only reduces soil fertility but also significantly impacts groundwater quality, leading to detrimental effects on crop yields and ecosystem health. Date palm (Phoenix dactylifera) cultivation, a key agricultural practice in many arid regions, often relies on saline groundwater for irrigation due to limited freshwater resources and low precipitation rates. The use of saline water can create an intricate balance between providing necessary nutrients and introducing harmful salts into the soil. While the role of …

Biological Sciences: Faculty Publications
In contrast to the typified view of genome cycling only between haploidy and diploidy, there is evidence from across the tree of life of genome dynamics that alter both copy number (i.e. ploidy) and chromosome complements. Here, we highlight examples of such processes, including endoreplication, aneuploidy, inheritance of extrachromosomal DNA, and chromatin extrusion. Synthesizing data on eukaryotic genome dynamics in diverse extant lineages suggests the possibility that such processes were present before the last eukaryotic common ancestor. While present in some prokaryotes, these features appear exaggerated in eukaryotes where they are regulated by eukaryote-specific innovations including the nucleus, complex cytoskeleton, …

Clock Hijackers: How Integration Of Glioblastoma Into Circadian Circuits Regulates Tumor Progression And Sensitivity To Current Therapies, Maria Felicita Gonzalez
Arts & Sciences Graduate Student Theses and Dissertations
Glioblastoma (GBM) is the most common primary brain tumor in adults with a poor prognosis despite aggressive therapy. A recent, retrospective clinical study found that administering chemotherapy with Temozolomide (TMZ) in the morning increased patient overall survival by 6 months compared to evening. Previous work has shown that murine and human models of GBM have cell-intrinsic circadian rhythms in expression of the core clock genes Bmal1 and Per2 in vitro. This suggests that GBM has circadian rhythms that entrain to the hosts’ central clock. Understanding the mechanisms underlying circadian entrainment and tumor growth in GBM is essential to determine whether …
