Piping Up: Exploring Body Length And Density Metrics Of Dominant Pipefish Species Urocampus Carinirostris Across Spatially Distinct Sites In Moreton Bay, Qld, Leah Esser

Australia: Rainforest, Reef, and Cultural Ecology

The morphologically unique family Syngnathidae faces high levels of anthropogenic pressures in Moreton Bay Marine Park where seagrass beds, habitat to many syngnathid species, are increasingly vulnerable. Among these species, the pipefish Urocampus carinirostris is especially prevalent, making it a strong candidate as an indicator and model species. Threats to seagrass, including pollution and nutrient overload, largely stem from sources on the bay’s western banks. This study aimed to conduct a preliminary investigation of how U. carinirostris size, density, and site-level pipefish diversity compares across locations, with particular attention to differences between eastern and western sites. An exploratory comparison between …

Surveys were done on Lizard Island in the Great Barrier Reef, and the study site was Horseshoe. Horseshoe is a shallow reef located on the sheltered side making it easy to survey at. During a 3 day span …

Blooming Questions: The Potential Impact Of The Ongoing Harmful Algal Bloom On Pinnipeds On Kangaroo Island, South Australia, Rose Cassidy

Australia: Rainforest, Reef, and Cultural Ecology

The ongoing harmful algal bloom in South Australia that began in March 2025, which resulted in over 106 marine animal mortalities across 550 taxa, was recently identified as having brevetoxins, which can harm marine mammals and human beings (Murray et al., 2025). This algal bloom is currently affecting Kangaroo Island, South Australia, a key habitat for the endemic Australian sea lion (Neophoca cinerea), as well as long-nosed fur seals (Arctocephalus forsteri) (Goldsworthy et al., 2021), (Goldsworthy and Shaughnessy, 1994). Because these pinniped species were observed eating algal bloom affected prey, previous research on other pinnipeds suggests that the subject pinnipeds …

K847a Mutation And Anionic Lipid-Presence Modify Opa1 Enzyme Kinetics And Function, J. Rafael Tolentino, Kate Walsh, Andrew D. Kehr

Annual Student Research Poster Session

Opa1 is a dynamin superfamily protein that is responsible for the fusion of the mitochondrial membrane. However, nobody knows the specific chemical mechanisms of how it interacts with lipids. Our research focuses on investigating how Opa1 interacts with lipids. In other words, we want to figure out which amino acids are crucial for Opa1's ability to bind with lipids. In hopes of understanding how Opa1 mutations affect neurodegenerative diseases, such as dominant optic atrophy.

Investigating The Effects Of Cbd And Caffeine Interaction On Embryonic Development In Xenopus Laevis, Jeanesia M. Pierre

Theses

This study examined the interactive effects of cannabidiol (CBD) and caffeine on Xenopus laevis embryos over a 96-hour exposure period. Developmental toxicity was assessed using toxic unit isobole analysis, with LC₅₀, EC₅₀, and teratogenic index (TI) values calculated for CBD, caffeine, and mixtures at 3:1, 1:1, and 1:3 ratios.

Results showed that mixtures produced concentration-dependent interactions. When caffeine levels were higher, the mixtures displayed synergistic toxicity; as the proportion of CBD increased, the interaction shifted toward a concentration-addition model. Mortality was elevated in mixtures relative to single-compound exposures, while malformation rates decreased, indicating reduced teratogenicity. Overall, findings suggest that CBD …

Asymmetric Interdependence In Tunisian–Algerian Energy Relations, Samuel Harlow

Tunisia and Italy: Politics and Religious Integration in the Mediterranean

This research interprets contemporary Tunisian–Algerian relations through the

lens of asymmetric interdependence, offering a nuanced analysis of the power

dynamics embedded in their energy relationship. Employing a disciplined

configurative case study design, the study systematically applies established

theories of asymmetric interdependence, particularly relative vulnerability and

the influence effect, to energy trade data, oil and natural gas infrastructure, and

patterns of fiscal and emergency assistance. The analysis demonstrates that

Algerian energy policy and financial support have contributed to an

interdependent relationship in which Algeria is relatively less vulnerable than

Tunisia, generating latent conditions for economic influence without asserting

that coercive instruments …

Anterior Cingulate Cortex Connectivity And The Role In Neuroticism: A Diffusion-Weighted-Imaging-Based Investigation Of Limbic And Prefrontal Circuits., Jake Cox Ii

College of Arts & Sciences Senior Theses

Neuroticism is a trait which has been shown to significantly predict psychopathology. Investigating its neurobiological underpinnings may uncover a brain-based relationship that allows clinicians to conceptualize a shared predispositional factor across multiple psychopathologies, implicating treatment protocols. Inter-connectivity network and structural variation has been shown to be implicated in neuroticism, more specifically the frontoparietal network, default mode network, salience networks, and limbic networks. These networks tackle executive, salience, and emotional information, respectively. The anterior cingulate cortex (ACC) is a brain region nested between and functionally related to various networks stated above that are implicated in neuroticism. As such, it was hypothesized …

Cytotoxic Effects Of Microplastics On A549 Lung Cancer Cells, Tykel Eddy

Theses (2016-Present)

Investigation of cytotoxic effects of 10μm polystyrene based microplastics on A549 lung cancer epithelial cell line utilized multiple in-vitro assays. Cell viability was analyzed and compared between the control and treated groups using MTT assay using three separate doses (25, 50, and 100 μL). Results indicated that dosage was not a factor, but mainly, a significant time dependency of exposure to microplastics for treated cells compared to control group. Live/Dead assay gave a visual representation of microplastic cytotoxic effects as over the course of three days there was an increase of dead cells withing the treated group, as confirmed by …

Assessment Of Genes And Mirnas Expression In Alzheimer's Disease Samples Using Single And/Or Multiplex Preferential Amplification Pcr, Samanda F. Hickman

Theses (2016-Present)

Gene expression is measurable at the RNA and protein levels. It is a process by which genes produce functional products that are either non-coding RNAs or proteins. The non-coding RNAs or proteins of gene expression ultimately affect phenotype. Non-coding RNA (or mRNA) expression is measured by Northern blot or real-time quantitative PCR (RT-qPCR), while Western blot measures protein expression. Both require software to differentiate between the amounts of end products. Statistical analysis is employed to validate any differences among the measured values and to infer a correlation between the end products of various samples. There are several neurodegenerative diseases, including …

The Impact Of Long-Term Exposure To Lip Cosmetics On The Fertility Of Female Drosophila Melanogaster, Neeka Oghli

Holster Scholar Projects

Are products marketed as safe to use, truly safe to use? Inspired by an article exposing the dangers of Tampax tampons, this study examines potential reproductive risks from consumer lip products marketed as natural and safe18. Drosophila melanogaster, a model organism with genetic and reproductive similarities to humans, was utilized to test the impacts of Rhode and Avène lip cosmetics. Avène’s Cicalfate + Lips Repair Lip Balm is the closest alternative to Rhode’s unscented peptide lip treatment, which was mindfully chosen to test if affordability comes at the expense of safety. Various concentrations of these products will be exposed to …

Obstetrics and Gynaecology, East Africa

Human papillomavirus 16 (HPV16) drives precursor cervical lesions that often progress to cervical cancer (CC). Variation within the HPV16 genome has been associated with CC risk. Here, we developed an affordable and portable amplicon-based long-read whole genome sequencing (WGS) approach using Oxford Nanopore Technologies to investigate HPV16 genetic diversity among women in sub-Saharan African countries. Applied to a control CaSki cell line and clinical samples (n = 12), our method generated complete HPV16 genomes at high coverage (median read coverage: 5,899–15,279 ×). Benchmarking our HPV16 controls showed high accuracy for two variant calling pipelines (Clair3 and PEPPER-Margin DeepVariant). Phylogenetic analysis …

Compost Grinder For The University Of South Carolina Office Of Sustainability, Rori E. Pumphrey, Grace Yaegel, Aaron R. Sawyer, Bradley White

Senior Theses

This project originates from a collaboration with the USC Office of Sustainability, which seeks to improve the handling and processing of food waste generated on campus. The primary challenge is the difficulty in composting certain types of food waste, such as avocado pits, pumpkin rinds, and other dense or fibrous organic materials that are not easily broken down using conventional methods. Existing commercial solutions are often too large and expensive, or electrically powered, and are thus not well suited for the volume or nature of USC's food waste. To address these limitations, our team designed a manually operated food waste …

Assessing Expected Cover Of Invasive Flora Species Near Corridor Features By Distance, Joshua G. Logan

Theses

Fragmentation of landscapes has been a growing topic of interest within scientific literature over the past several decades, as the way we as humans affect our planet becomes more apparent as the years go on. As humans, we have shaped the land and what it contains in immeasurable ways, erasing or forever altering entire natural ecosystems. Chief among the drivers altering these ecosystems is the fragmentation of landscapes, which can have all kinds of effects on natural ecosystems, from limiting nutrient transport to providing easier access for invasives to permeate throughout a landscape. Corridors are significant areas of interest regarding …
