Argentina: People, Environment, and Climate Change in Patagonia and Antarctica

This study seeks to understand how ecological imperialism present in urban green spaces affects the optimal functioning of the reciprocal economies that sustain these places, through the case of Plaza Almirante Brown in Río Grande, Tierra del Fuego, Argentina. The perceptions, values, and emotions that visitors attribute to this urban ecosystem are analyzed, as well as the social dynamics that keep it alive. The work acknowledges and respects the sense of place already established, while identifying a gap in the plaza's relational economy linked to the limited presence and public understanding of native flora. It proposes that the incorporation of …

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 …

Urban Noisy Miner Populations And Vegetation Composition Hinders Small Bird Communities In Urban Sydney, Australia And Canberra, Australia, Libby Hennes

Australia: Rainforest, Reef, and Cultural Ecology

Increasing urbanization to prioritize habitats that are eucalypt dominant with poor understory density has resulted in an overabundance of the native honeyeater the Noisy Miner (Manorina melanocephala). Noisy Miners are incredibly aggressive, especially towards birds that are smaller than them. This is believed to have contributed to declining small bird populations in remnant woodland patches that are dominated by Noisy Miners. This same pattern was discovered in urban greenspaces across Sydney, Australia and Canberra, Australia during November 2025. Small birds were almost completely absent in sites in Sydney and small birds in Canberra had a strong negative correlation with the …

J.A.M: What Epiphyte Load And Frugivore Abundance In Ficus Species Can Tell Us About Disturbance Regimes In Tropical North Queensland, Jordan Trinidad

Australia: Rainforest, Reef, and Cultural Ecology

The Wet Tropics Bioregion hosts a startling diversity of species, many of which are endemic and/or endangered. The habitats in which these species are found have been threatened by intensive logging post-European settlement, which has increased the susceptibility of the isolated remnant fragments to cyclone-related disturbances. In this study, we surveyed the visitation rates of frugivores to Ficus species between Cape Tribulation and Yungaburra in Northeast Queensland, Australia, as well as the epiphyte abundance supported by these trees. We found that in upland rainforest, the forces of cyclones and habitat fragmentation act in confluence on epiphyte abundance via the moderation …

Effects Of Provisioning On Two Species Of Rock-Wallaby (Petrogale Mareeba And Petrogale Assimilis) In North Queensland, Australia, Eve Oliker

Australia: Rainforest, Reef, and Cultural Ecology

Provisioning, the act of providing food, water, or shelter to wild animals, can lead to habituation, resulting in changes in behavior, abundance, and distribution (Newsome & Rodger, 2008). In North Queensland, a colony of Mareeba rock-wallaby (Petrogale mareeba) at Granite Gorge has been provisioned for over 45 years, mainly through direct hand-feeding, while a group of allied rock-wallaby (Petrogale assimilis) in Magnetic Island has experienced shorter and less consistent provisioning. This study investigated whether long-term provisioning causes more severe behavioral changes, higher aggression, and larger aggregation sizes. Approximately one week was spent observing each population. Scan sampling was utilized to …

Australia: Rainforest, Reef, and Cultural Ecology

The habitat preferences and activity budgets of platypuses (Ornithorhynchus anatinus) was recorded in the Hobart Rivulet in Hobart, Tasmania. Twenty-three sites were sampled for platypus presence over 21 days for a total of 784 surveys at various times between 6:00 and 20:00 during which current weather and river conditions were recorded. Fifty-eight platypuses were observed, and their behaviors were recorded in 15-minute periods for a total 5.86 hours of behavioral data. During observations the type and duration of their behaviors was recorded. The habitat assessment at the sites included factors that may impact platypus occurrence, behavior, or abundance such as …

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 …

Relating Natural Dispersal And Expansion Of Mangrove Forests To Local Australian Restoration Methods, August Jones

Australia: Rainforest, Reef, and Cultural Ecology

The combined vulnerability and importance of mangrove forests have spurred efforts to preserve their remaining natural stage and restore their land area made unsuitable by storms or coastal development. Globally, both private and government organizations have participated in mangrove ecosystem recovery through standard methodology and principles such as replantation and ecosystem rehabilitation. However, research into the costs and outcomes of these programs has ruled that many of them suffer low success rates due to a lack of suitable areas for rehabilitation, citing a poor understanding of the ecosystem typology and lack of long-term measures to avoid eventual degradation. This study …

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 …

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 …

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 …

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 …
