A Series Of Investigations On The L. Cornutus Host System And Bivesiculid Sp. Cercariae, Briana K. Zaffiro
All HCAS Student Capstones, Theses, and Dissertations
Rising global temperatures are likely modulating parasite-host interactions, yet the direction and magnitude of these changes remain uncertain. Rarely are these interactions viewed from both a host and parasite perspective. Using both CTmax, or Critical Thermal Maximum, and Clark-type polarographic oxygen microelectrodes, the physiological metabolic effects are investigated. CTmax is examined in Common Shiners, Luxilis cornutus, and is shown to be modulated by parasitism: uninfected fish had the highest CTmax average of 37.0°C, whereas heavily infected fish had decreased CTmax averaging 35°C. Prior to the parasite metabolic investigation, a suitable medium was determined, as …

Transcriptomic Responses Of Teleost Fishes To Thermal And Environmental Stress: A Synthesis Of Rna-Seq Studies, Aleen Ammar
Transcriptomic Responses Of Teleost Fishes To Thermal And Environmental Stress: A Synthesis Of Rna-Seq Studies, Aleen Ammar
Theses, Dissertations and Culminating Projects
Climate change is driving rapid shifts in aquatic ecosystems, increasing the frequency and intensity of environmental stressors that affect survival, species distributions, and productivity. Alongside increases in temperature, stressors, such as hypoxia and acidification, are also intensifying with climate change. Teleost fishes exhibit substantial variation in tolerance to such environmental stressors. These range from specialists with narrow limits to generalists capable of persisting across fluctuating conditions, complicating predictions of vulnerability under ongoing environmental change. Transcriptomic approaches, particularly RNA sequencing (RNA-seq), provide a powerful approach for linking environmental stressors to physiological responses by quantifying genome-wide changes in gene expression. To assess …

Assessing Decadal Changes In Eelgrass Communities From Barnegat Bay, Nj, Janelle Marie Delcastillo
Theses, Dissertations and Culminating Projects
Zostera marina (eelgrass) is a widely distributed marine angiosperm across northern hemisphere coastlines, yet many regions have experienced substantial declines due to disease, coastal development, and other anthropogenic stressors. Barnegat Bay is the only estuary in New Jersey that still supports extensive eelgrass beds, although it has undergone notable losses over the past five decades. To evaluate decadal-scale ecological change, we collected sediment cores in 2025 from a site with historical data spanning 2001–2010. Overall faunal densities remained relatively consistent, but several taxa exhibited clear shifts in abundance. Amphipods in the Phoxocephalidae and the isopod Erichsonella increased, whereas the cold-affinity …

Evaluation Of Flt3 Inhibition With Quizartinib During Busulfan Conditioning For Hematopoietic Stem Cell Transplantation, Catherine Jankovic
Evaluation Of Flt3 Inhibition With Quizartinib During Busulfan Conditioning For Hematopoietic Stem Cell Transplantation, Catherine Jankovic
Biochemistry and Molecular Biology
Hematopoietic stem cell transplantation (HSCT) is one of the only curative therapy options for many hematologic malignancies. HSCT relies on effective conditioning regimens to deplete host hematopoietic cells and enable donor engraftment. The alkylating agent Busulfan is widely used in myeloablative conditioning strategies due to its potent cytotoxic effects on hematopoietic cells and ability to clear the bone marrow. However, optimization of conditioning strategies remains an important area of investigation to improve transplant outcomes and reduce toxicity. Preliminary studies have shown that the FLT3 inhibitor Quizartinib synergizes with some chemotherapeutic agents, suggesting that targeted inhibitors may enhance conventional conditioning regimens. …

Forest Overstory Mortality & Recruitment Patterns Eight Years Following Wildfire In The Southern Appalachians, Ruth Cumberland
Forest Overstory Mortality & Recruitment Patterns Eight Years Following Wildfire In The Southern Appalachians, Ruth Cumberland
All Theses
In this study, we investigated patterns of forest overstory mortality and recruitment eight years after wildfire in a large wildfire site the Southern Appalachians, a topic that has not been thoroughly investigated to date. With evidence that pre-fire drought promotes post-fire mortality through impaired physiological function and increased fuel consumption, unknown patterns following wildfire are important to study under shifting climate and land-use conditions. In Chapter 1, three areas of interest were investigated: (a) functional group mortality response to wildfire effects, (b) temporal differences in early (1-3 years) and late (5-8 years) periods of delayed forest overstory mortality patterns following …
Identification, Pathogenicity, And Fungicide Sensitivity Of Itersonilia Perplexans Associated With Petal Spot Of Gerbera Cut Flowers In Colombia, Matheus Beger
All Theses
Petal diseases significantly affect gerbera cut flower production, as minor visual damage renders flowers unmarketable. Among those pathogens causing petal spots, Itersonilia perplexans affects some Asteraceae plants. However, this pathogen's impact on Colombian gerbera remains poorly studied. This study was designed to fill four gaps: molecular identification of Colombian isolates, confirmation of pathogenicity, standardized culture media, and fungicide sensitivity data. Four objectives were pursued: (i) isolate and identify the causal agent through sequencing the Internal Transcribed Spacer, Small Subunit and Large Subunit from the rDNA; (ii) evaluate pathogenicity on detached gerbera petals; (iii) identify optimal culture media for I. perplexans …

Identifying The Role Of Human Dna Polymerase Delta During Human Cytomegalovirus Genome Synthesis, Rachel Laree Dansereau
Identifying The Role Of Human Dna Polymerase Delta During Human Cytomegalovirus Genome Synthesis, Rachel Laree Dansereau
Dartmouth College Master’s Theses
Human cytomegalovirus (HCMV) is a large double stranded DNA virus and member of the Herpesviridae family. Like all herpesviruses, HCMV presents with characteristics of persistent, lifelong infections that transition between lytic and latent states. The replication of the viral genome is traditionally thought to occur by a rolling circle mechanism, but this model is supported by little evidence. It is known that HCMV actively recruits several host proteins to viral replication compartments (RCs), including proteins involved in the DNA damage response (DDR). The exact mechanisms of how these proteins are used and in what ways they help the virus remain …
Using The Flexon Approach To Rnai For Analysis Of Gene Function In Gonadal Development In C. Elegans, Andrew D. Spalding
Using The Flexon Approach To Rnai For Analysis Of Gene Function In Gonadal Development In C. Elegans, Andrew D. Spalding
Undergraduate Theses
C. elegans, a nematode worm, was used as a model organism to analyze the developmental effects of knocking down the expression of genes that are both essential to worm viability and highly enriched in reproductive tissues. In earlier research, approximately 70 C. elegans genes were identified that are both gonad-enriched and essential. To prioritize which genes should be the focus of future studies, a new strain of C. elegans was produced with three specific genetic variations that: 1) silence essential, somatic gonad-enriched gene expression, 2) limit the effects of this gene silencing to the gonad, and 3) yield a …
Expanding Access To Noninvasive Spinal Neuromodulation For Pediatric Spinal Cord Injury Rehabilitation: A Comparative Device Study, Alice E C Palmer
Expanding Access To Noninvasive Spinal Neuromodulation For Pediatric Spinal Cord Injury Rehabilitation: A Comparative Device Study, Alice E C Palmer
College of Arts & Sciences Senior Theses
Paralysis following spinal cord injury (SCI) has traditionally been considered permanent due to the disruption of supraspinal input to spinal motor circuits. However, growing evidence suggests that spinal networks below the level of injury retain intrinsic motor-generating capabilities through central pattern generators. Transcutaneous spinal cord stimulation (scTS) is a noninvasive neuromodulation technique that delivers electrical stimulation through the skin to reactivate these spinal networks. Although prior studies demonstrate that scTS delivered through research-grade devices is safe and effective in adults and children with chronic SCI, clinical translation remains limited by lack of FDA-approved systems, high costs, and restricted access to …
Using A Toxic Aging Coin To Assess Hexavalent Chromium Neurotoxicity: Impact Of Cr(Vi) On The Blood-Brain Barrier, Liam Buchanan
Using A Toxic Aging Coin To Assess Hexavalent Chromium Neurotoxicity: Impact Of Cr(Vi) On The Blood-Brain Barrier, Liam Buchanan
College of Arts & Sciences Senior Theses
The US population faces simultaneous public health threats from both aging and environmental pollutants. Chief among these is hexavalent chromium [Cr(VI)], whose toxic effects in peripheral tissues are well-established but its effects on the brain are still understudied. Following previous results indicating hippocampal metals dyshomeostasis after Cr(VI) exposure, we aim to assess Cr(VI)’s impact on the blood-brain barrier (BBB), a key structure for brain protection. We exposed young, middle-aged, and geriatric rats of both sexes to low levels of Cr(VI) in their drinking water for 90 days, after which we used immunofluorescence and confocal microscopy to analyze tissues for evidence …
Cholesterol Effect On The P-Glycoprotein Conformational Dynamics, Zane Bunn
Cholesterol Effect On The P-Glycoprotein Conformational Dynamics, Zane Bunn
Biological Sciences Undergraduate Honors Theses
P-Glycoprotein (Pgp) is a human efflux pump that belongs to the ABC transporter family. This protein consists of two transmembrane domains (TMD) that convert between inward to outward facing configurations to remove a wide variety of structurally different compounds from the intracellular membrane into the extracellular space using ATP. This non-specific efflux of compounds has brought Pgp to scientific light as having a major role in multi-drug resistance of many diseases, and researchers are focused on developing a deeper understanding of the protein. To further this understanding, this study analyzed how the structure of Pgp is affected by a 10% …
Hormonal, Cytokinetic, And Skeletal Response To A Single Weighted Vest Exercise Treatment: A Pilot Study To Determine Weighted Vest “Rucking” Treatment For Osteoporosis In Post-Menopausal Women, Eleanor Pell
Master's Theses
Osteoporosis is characterized by a deteriorating of bone tissue leading to brittleness and increased fracture risk that affects both men and women as they age. Postmenopausal women are of particular interest due to high risk of declining bone density, a characteristic of this population. Treatments for osteoporosis range from menopause hormone therapy, bisphosphonates, biologics, nutritional changes, and exercise. Load bearing exercise interventions have shown effectiveness for stimulating bone growth, but many factors such as lack of access, motivation, self-confidence or knowledge, prevent long term compliance. “Weighted vest rucking” refers to a variation of rucking, which is a form of exercise …
Companion Parrot Vocal Learning And Reproduction Of Human Speech Sounds, Karla Vilches Castaño
Companion Parrot Vocal Learning And Reproduction Of Human Speech Sounds, Karla Vilches Castaño
Master's Theses
Vocal learning is rare among animals but is well developed in parrots, which can imitate novel sounds and, in captive settings, reproduce human speech. This study helps address a larger evolutionary question about vocal learning. Specifically, whether vocal learning ability is best understood as a single generalized trait or as a multi-dimensional system in which different acoustic features can be learned and reproduced with varying degrees of fidelity. This thesis quantifies how closely companion parrots match their human tutors across three acoustic dimensions (spectrographic structure, intensity contour, and pitch contour) and tests whether mimicry accuracy varies among individuals, differs between …
Investigating The Taxonomic Uncertainties Of Potentilla Rupincola, Natalie Elizabeth Hieber
Investigating The Taxonomic Uncertainties Of Potentilla Rupincola, Natalie Elizabeth Hieber
Master's Theses
Landscape stewardship is an integral role for land managers that becomes more important when rare or endangered species occur within managed areas. Conservation across the landscape is a primary concern for land managers, but resources allocated for conservation can be limited due to many competing goals. Taxonomic uncertainty surrounding rare and endangered taxa, particularly plant taxa, that have historically been classified solely using morphological features further complicates conservation planning. One such taxon is Potentilla rupincola, a rare plant endemic to the eastern Rocky Mountains in Colorado. For over a century, botanists have debated whether P. rupincola is a distinct species …
