Fisheries Research Report No. 354: Recreational Fishing For Abalone In Western Australia In 2024/2025 - Estimates Of Participation, Effort And Catch, Claire B. Smallwood, Karina L. Ryan, Lachlan W. Strain

Fisheries Research Reports

The Western Australian Recreational Abalone Fishery (RAF) operates in shallow coastal waters as a hand collection fishery while wading or diving. Three species of abalone are allowed to be caught. Roe’s abalone (Haliotis roei) are generally collected while wading from the shore in accessible nearshore reef complexes along the West and South Coast Bioregions. Greenlip abalone (H. laevigata) and Brownlip abalone (H. conicopora) are collected while wading (including snorkelling and freediving) and diving (using compressed air) predominantly along the South Coast Bioregion.

Recreational fishing for the three abalone species is licensed and highly regulated, especially in the Western Zone (which …

Designing Portugal’S Voluntary Carbon Market: Insights From Key Stakeholders, Mahika Shergill

Portugal: Sustainability and Environmental Justice

This project examines the design, integrity, and early implementation challenges of Portugal’s newly established Voluntary Carbon Market (VCM), created through Decree-Law 4/2024 as part of the country’s broader climate-mitigation strategy. The objective of the study is to evaluate whether the market’s regulatory architecture—particularly its treatment of additionality, permanence, methodologies, and co-benefit mechanisms—positions it to function as a credible and viable national carbon-governance instrument. The analysis draws on a mixed-methods approach combining legal and policy review with four semi-structured interviews conducted with policymakers, methodological designers, ecological practitioners, and environmental-law specialists. These interviews reveal that Portugal’s VCM is characterized by strong integrity …

When The Water Runs Out: Modelling Portuguese Pumped Hydro Storage Adequacy In Multi-Year Extreme Drought Conditions, Meg Gillies

Portugal: Sustainability and Environmental Justice

Portugal’s reliance on Pumped Hydro Storage (PHS) to support grid stability poses increasing risks as the share of renewables in the national energy mix approaches the 2030 goal of 85%, and droughts intensify across the Iberian Peninsula (Silva, 2024). Because simulation tools like EnergyPLAN model only one year at a time, they overlook the cumulative effects of prolonged hydrological stress (Lund, 2024). This research addresses that gap by implementing an iterative multi-year approach in EnergyPLAN, linking yearly simulations to assess how extended drought conditions impact PHS performance. Using a detailed 2024 model of Portugal’s power system and applying dry year …

A Comprehensive Nutrition Education Program Promotes Behavior Change And Perception Of Food Access Across The Older Adult Age Span, Sarah Misyak, Camille Mcguire, Victor Olayemi, Maria Denunzio, Paige Harrigan, Elena Serrano

Journal of Human Sciences and Extension

Strategies to promote healthy behaviors among older adults are needed to mitigate vulnerabilities to negative health outcomes, especially for those with low income. Healthy Eating and Staying Active as We Age (HESA), a nine-lesson educational series for Supplemental Nutrition Assistance Program-eligible older adults, was created to promote health among aging audiences. The purpose of this study was to evaluate the behavior change of older adults following participation in HESA, which covers food resource management, nutrition, food safety, and physical activity behaviors, as well as perceived food affordability and accessibility, and to determine if HESA is appropriate across the age span …

Empowering Public Employees For Retirement Security: Evidence From A Pre-Retirement Financial Education Program, Suzanne Bartholomae, Mengya Wang

Journal of Human Sciences and Extension

The United States is facing a retirement crisis, with eight in ten older adult households experiencing or at risk of financial insecurity (Tavares et al., 2024). National data shows 60% of Americans regularly contribute to retirement accounts, and just 40% have estimated their retirement savings needs (Lin et al., 2022). With approximately 5,900 Baby Boomers retiring daily (Fry, 2019), there is considerable interest in identifying effective strategies and policies to address retirement preparedness. This paper presents evaluation findings from a retirement planning financial education program delivered to 750 public employees by Iowa’s public employee retirement system and Cooperative Extension educators. …

Mhc Gene Analysis And Immune Variation In Lepidodactylus Lugubris (The Mourning Gecko), Helen T. Vu

2025 Fall Honors Capstones Projects - Archive

The major histocompatibility complex (MHC) plays a central role in vertebrate immune defense by enabling pathogen recognition and initiating adaptive immune responses. While MHC diversity has been extensively studied in sexually reproducing species, comparatively little is known about its evolution in asexual lineages. The parthenogenetic gecko Lepidodactylus lugubris provides a unique opportunity to investigate how clonality and hybrid origins influence immune gene diversity. By leveraging whole-genome data, this study overcomes the limitations of previous transcriptome-based analyses and provides a more comprehensive view of MHC diversity in a clonal vertebrate. As the first step towards understanding MHC evolution in parthenogenetic lizards, …

Grpa-Prs: A Risk Stratification Method To Identify Genetically-Regulated Pathways In Polygenic Diseases, Xiaoyang Li, Brisa S Fernandes, Andi Liu, Jingchun Chen, Xiangning Chen, Zhongming Zhao, Yulin Dai

Faculty, Staff and Student Publications

Introduction: Polygenic risk score (PRS) assesses genetic risk for diseases, yet some high-risk individuals avoid illness while low-risk individuals develop it. We hypothesize that unknown counterfactors may reverse PRS predictions, offering insights into disease mechanisms and interventions.

Methods: We developed a novel framework to identify genetically-regulated pathways (GRPas) using PRS-based stratification in Alzheimer's disease (AD) and schizophrenia (SCZ) cohorts. We calculated PRS models, stratified individuals by risk and diagnosis, and analyzed differential GRPas. For AD, analyses were further conducted with and without apolipoprotein E (APOE) effects, and across APOE haplotype.

Results: In AD, we identified several well-known AD-related pathways, including …

Genetic Entropy: A Critical Examination, Sarah Hunter

Science, Faith, and Origins

Genetic entropy is a hypothesis proposing that genomes deteriorate over time due to the gradual accumulation of slightly harmful mutations that natural selection cannot effectively remove. This paper explores the scientific debate surrounding this claim by examining differing perspectives on the theory of genetic entropy. Proponents of genetic entropy, such as John Sanford, argue that most mutations are deleterious and fall within a “near-neutral” range, allowing them to accumulate since their effects are too small for natural selection to detect. Evidence to support this claim includes Robert Carter and John Sanford’s research on the deterioration of the H1N1 viral genome …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

Public Perception And Awareness Of Shark Nets In New South Wales, Drew Rosenfeld

Australia: Rainforest, Reef, and Cultural Ecology

Shark nets have been in use along the beaches of New South Wales since 1937, with the purpose of the nets to reduce human shark encounters near popular beaches. While the purpose of the nets is to protect personal safety, the nets also entangle and harm non target marine life. This study examined public perception and awareness of shark nets in NSW through a mixed method approach that utilized survey and interview data. In total, 201 surveys were administered on Bondi and Coogee beach. Five interviews were also carried out with key stakeholder groups. Results have shown that public perception …

Learning From The Roost: An Exploration Of Public Perceptions And Education Around Grey-Headed Flying Foxes At Centennial Parklands, Sydney., Gigi Pandole

Australia: Rainforest, Reef, and Cultural Ecology

Grey-headed flying foxes (Pteropus poliocephalus) have become a familiar feature of many Australian cities, and this visibility often prompts a mix of curiosity, uncertainty and concern. In Sydney, the long-term colony at Lachlan Swamp in Centennial Parklands brings thousands of visitors into close contact with the species each week. Some people respond with interest or appreciation, while others feel uneasy due to noise, smell or common misconceptions about disease. These everyday encounters raise an important question for conservation: how do people form their perceptions of flying foxes, and what role does education play in shaping coexistence in urban environments? This …

Why Antimicrobial Resistance Pipelines Fail On Cyanobacteria: What Custom Databases Reveal Instead, Maeve Musselman

Australia: Rainforest, Reef, and Cultural Ecology

Harmful cyanobacterial blooms (C-HABs) are increasing as climate change and nutrient enrichment create favorable environments for cyanobacteria. Although bloom-forming cyanobacteria can persist in extreme and polluted conditions, and antimicrobial resistance (AMR) and metal resistance (MR) play significant roles in bloom persistence and response to treatments, both remain understudied. Currently, most AMR detection pipelines use clinical databases developed for human pathogens which routinely fail to detect resistance genes in environmental microbes. This study evaluated AMR and MR profiles in seven freshwater cyanobacteria using both clinical AMR pipelines (CARD, ResFinder, ARG-ANNOT) and a custom environmental resistance database specifically designed to include metal …

Contradicting Effects Of Three Firefighting Chemicals On Batrachochytrium Dendrobatidis Infection, Naomi Meyers

Australia: Rainforest, Reef, and Cultural Ecology

The spread of Batrachochytrium dendrobatidis around the world has led to the decline of many species; however, Australian amphibian populations are especially vulnerable to the effects of the fungus. The combination of endemism, small geographical ranges, and a climate that supports fungal growth has led to the presumed extinction of 6 endemic species since the disease was first discovered. In addition to this fungus, amphibians are also facing pressure from the increasing prevalence of wildfires. As wildfires become more common and more destructive, scientists are rushing to find chemicals that aid firefighters in slowing down and reducing the intensity of …

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 …

Illustrated Key To Third Instar Larvae Of Forensically Important Calliphoridae From Costa Rica, Roberto Esteban Morales-Montero

Department of Entomology: Distance Master of Science Projects

Forensic entomology in Costa Rica formally began by the end of the 1990s decade, however, the keys utilized to identify the species of Calliphoridae, the most important family of flies that colonize decomposing bodies in Costa Rica, are a compendium of work done by different authors that not include all the species present in the country, and are not adequately illustrated, which could make the analyses difficult for people without the proper knowledge of the carrion flies, or may lead to errors in the identification. The objective of this work is to put together a properly illustrated key for third-instar …

Insect Biodiversity Of Prairie Land Based On Prescribed Fire Plans In Central Iowa, Katelyn Rodriguez

Department of Entomology: Distance Master of Science Projects

Introduction

Insects play a crucial role in the prairie ecosystems by helping to maintain a healthy balance in various aspects of human life. They play vital roles in assisting with pest control, waste decomposition, and the pollination of plants and crops (The Nature Conservancy, 2021). Additionally, they can serve as indicators of an environment's health, such as nutrient cycling in water and soil formation in crop fields (The Nature Conservancy, 2021). Insect biodiversity is a crucial component in ensuring our environment is adequately cared for, and in turn, other aspects of life that rely on insect relationships.

Does Increasing Canopy Liana Density Decrease The Tropical Forest Carbon Sink?, Stefan A. Schnitzer, David M. Defilippis

Biological Sciences Faculty Research and Publications

The ongoing decline in the American tropical forest carbon sink has serious ramifications for atmospheric carbon levels and global climate change. Increasing liana abundance may explain the decaying carbon sink because lianas reduce canopy tree growth and survival, which limits forest carbon storage. However, canopy lianas, not solely understory lianas, would have to be increasing for this hypothesis to be credible because canopy lianas compete especially intensely with canopy trees. We examined the change in canopy lianas over 10 years on Barro Colorado Island (BCI), Panama to test two main hypotheses. (1) Canopy lianas are increasing on BCI. (2) Increasing …

Hcmv Infection Of Terminally Differentiated Neurons Disrupts Microtubule Organization, Resulting In Neurite Retraction, Jacob W. Adelman, Andrew T. Sukowaty, Kaitlyn J. Partridge, Jessica E. Gawrys, Allison Akins, Scott S. Terhune, Allison D. Ebert

Biological Sciences Faculty Research and Publications

Human cytomegalovirus (HCMV) is a prolific human herpesvirus that infects most individuals by adulthood. While typically asymptomatic in adults, congenital infection can induce serious neurological symptoms, including hearing loss, visual deficits, cognitive impairment, and microcephaly in 10%–15% of cases. HCMV has been shown to infect most neural cells, with our group recently demonstrating this capacity in stem cell-derived forebrain neurons. Infection of neurons induces deleterious effects on calcium dynamics and electrophysiological function paired with gross restructuring of neuronal morphology. Here, we utilize an induced pluripotent stem cell-derived model of the human forebrain to demonstrate how HCMV infection induces syncytia, drives …

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 …

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 …
