Monitoring Faunal Responses To Biodegradable Oyster Reef Restoration Materials With Camera Traps, Tara L. Blanchard

Honors Undergraduate Theses

Restoration of the oyster reefs has become increasingly crucial due to great population declines around the globe. Intertidal oyster reefs provide essential foraging and loafing grounds to many faunal species, including several threatened/endangered wading bird species. Biodegradable oyster reef restoration materials have been introduced to avoid potential plastic pollution from traditional materials. Studies have shown success regarding oyster recruitment rates to these materials. However, their impacts on fauna using restored oyster reefs are unknown. This project aims to evaluate oyster reef restoration using biodegradable materials to increase faunal diversity, abundance, and foraging behaviors. Camera traps were deployed to observe fauna …

Honors Undergraduate Theses

Type 2 diabetes mellitus (T2DM), presents a significant health burden globally, affecting millions of individuals, especially in the elderly population. While its association with cardiovascular diseases and cognitive impairments is well-documented, further research on the precise influence of glucose control on cognitive outcomes in elderly T2DM patients is necessary. This scoping review aims to address this gap by investigating the impact of HbA1c levels representing glycemic control on the risk of developing cognitive impairments in elderly patients with T2DM. A literature search was conducted on MEDLINE and eligible studies involved T2DM patients aged 60 or older, with documented cognitive function …

The Ethics Of Brain-Machine Interfaces, Devon J. Lynn

Honors Undergraduate Theses

Brain Machine Interfaces (BMI) are a rapidly developing technology that raise unique ethical issues that demand review. They have demonstrated impressive restorative potential, particularly for individuals living with epilepsy, and those who are locked in. Although BMIs have the potential to provide significant benefit to millions of users, further advancement of the technology should proceed cautiously, according to the guidelines outlined in this paper. Failure to adhere to ethical guidelines could lead to severe privacy concerns, and would violate moral principles of beneficence, virtue ethics, care ethics, and utilitarianism. Despite the moral risks, BMIs hold promise for reshaping future healthcare …

Developing A Novel Gold Nanoparticle-Based Colorimetric Assay For The Detection Of Cytomegalovirus (Cmv) In Pediatric-Derived Urine Specimens, Sonam Gupta

Graduate Thesis and Dissertation 2023-2024

Cytomegalovirus (CMV) is a member of the Herpesviridae family and is known to infect people of all ages. In most cases, CMV infection is asymptomatic, and the virus is cleared from the host without showing any significant symptoms. However, 1 out of 200 babies are born with congenital CMV infection, which affects multiple organs, including the brain, liver, spleen, lung, and inner ear. One long-term health problem in 1 out 5 babies born with congenital CMV infection is hearing loss. The progression of CMV-associated hearing loss in the first two years of life may lead to developmental delays in language, …

Graduate Thesis and Dissertation 2023-2024

This study assessed the effect of an eight-minute cycling intervention using varying intensities on exercise-induced hypoalgesia (EIH). Generally, current research examines EIH using protocols that last for more than 10 minutes and reach 75% of an individual's VO2 peak. The main objective of this study was to examine the effect of varying intensities on pressure pain threshold (PPT) and heat pain threshold (HPT) at the thigh and forearm, tested pre- and post-cycling intervention.

Healthy male participants (n=16) performed a graded exercise test on a cycle ergometer to establish their peak power output (PPO). In subsequent visits, participants completed five different …

Examining Wrack In Mosquito Lagoon To Analyze Biodiversity And Seagrass Viability, Nicole Jerrell

Honors Undergraduate Theses

Seagrass restoration of Halodule wrightii, has become crucial as seagrass coverage in the Indian River Lagoon (IRL) declined by 58% between 2011 and 2019. To understand the abundance of seagrass fragments available for natural recruitment and restoration, we tracked the abundance of viable fragments found in the wrack in Mosquito Lagoon. Wrack is plant material, including seagrass fragments, mangrove propagules, and detritus. Seagrass fragments were considered viable if the fragment had an apical meristem present. Replicate samples were collected from 5 locations every two weeks, starting in September 2022 and ending in September 2023, and the samples were processed …

Sweetening The Deal: Enhancing Flower Production And Quality For Native Pollinators In Urban Landscapes, Yaelle Esther Reeve

Honors Undergraduate Theses

Urban landscapes can support pollinator conservation, but traditional landscape designs lack the diverse mixtures of native plants needed to support native pollinators. Although native plants support pollinators and can survive with less water and fertilizer than non-native landscape plants, they do not always grow well under modified urban soil conditions and irrigation regimes. A better understanding of the factors influencing flower production and the quality of native plants is needed if we are to design landscapes that support pollinator conservation. This study focused on how flower production and quality in different native plants responded to compost and irrigation treatments. The …

Rhizophora Mangle (Red Mangrove) Seedling Success In Different Habitats In Mosquito Lagoon, Florida, Usa, Mekail N. Negash

Graduate Thesis and Dissertation 2023-2024

Mangroves provide many ecosystem services in coastal environments around the world. These include water quality improvement, creating habitats for terrestrial and aquatic species, and stabilizing shorelines. In central Florida, the red mangrove Rhizophora mangle is a common species in coastal wetlands, and recently the number of individuals successfully recruiting to intertidal oyster reefs has greatly increased, possibly because biogeochemical hot spots are present on oyster reefs due to nutrient-rich biodeposits from the live oysters. To understand how well R. mangle responds in terms of survival and growth to the suite of variables associated within these two unique habitats, I tracked …

Climate Change And Coastal Development Impacts On Oyster Abundances In Mosquito Lagoon, Fl, Emily Suchonic

Graduate Thesis and Dissertation 2023-2024

Live eastern oyster (Crassostrea virginica) reefs have declined by 62.6% in Mosquito Lagoon (ML) along the eastern Florida coast since 1943. While this species creates reefs by successive generations of oysters recruiting to conspecific shells, C. virginica can also attach to non-reef substrates including mangrove roots and armoring (e.g., seawalls), which may help counteract reef habitat loss. In recent decades, warmer winters have enabled red (Rhizophora mangle) and black (Avicennia germinans) mangrove expansion in subtropical salt marshes and temperate estuaries where oyster reefs occur. Additionally, 11.8% of ML's shorelines have been armored as of …

Obsessive-Compulsive Disorder And Identity: The Role Of Ego-Dystonicity, Andrea B. Mullin

Honors Undergraduate Theses

Obsessive Compulsive Disorder (OCD) has been linked to a dysmorphic construction of self that is closely tied to mental illness (Bhar & Kyrios, 2007). Although associations have been found, no study has determined the impact of OCD on one's self-perception, to better understand how to resolve patients' dysmorphic construction and fear of oneself. College students (N = 410; M = 20.60, SD = 4.27) completed an anonymous online survey for course credit. The survey consisted of a demographic questionnaire, the Obsessive-Compulsive Inventory-Revised (Foa et al., 2002), theEgo-Dystonicity Questionnaire (Purdon et al., 2007), and the Self-concept Identity Measure (Kaufman et …

Benefits Of A Family-Based Judo Program For Parents Of Children With Autism Spectrum Disorder, Jeslin George

Honors Undergraduate Theses

A diagnosis of Autism Spectrum Disorder (ASD) can impact the entire family. Parents of children with ASD reportedly have greater stress levels, family conflict, financial concerns, and poor health habits than parents of neurotypical (NT) children. While many parent-focused interventions have been developed, these interventions focus on parent training and child behavior outcomes rather than the health and well-being of the parents. Therefore, this study aimed to examine the effects of a 15-week family judo program on physical and psychosocial health in parents of children with ASD. A total of 18 parents of children with ASD participated in a weekly …

Effect Of Molecular Crowders On The Activation Of Cholera Toxin By Protein Disulfide Isomerase, Niral Shah

Honors Undergraduate Theses

Cholera toxin (CT) is a classic A-B type protein toxin that has an A subunit (A1 + A2) and a pentameric B subunit. The catalytic A1 domain is linked to the A2 domain via a disulfide linkage. CTA1 must be dissociated from the rest of the toxin to cause a cytopathic effect. Protein disulfide isomerase (PDI) can reduce the CTA1/CTA2 disulfide bond, but disassembly of the reduced toxin requires the partial unfolding of PDI that occurs when it binds to CTA1. This unfolding event allows PDI to push CTA1 away from the rest of the toxin.

My research question is …

The Effect Of E-Cigarette Vape On Oral Cell Proliferation Using 3d Spheroids As A Preclinical Model, Vikram Chinnaiyan

Honors Undergraduate Theses

E-cigarettes have recently become increasingly popular, especially amongst middle and high school students. Although they are marketed as safer alternatives to tobacco cigarettes, they produce toxic metals and carcinogenic nitrosamines. This thesis studies the effects of e-cigarette aerosol on the growth and proliferation of oral epithelial cells because the consequences of vaping, including a potential risk for aberrant growth leading to cancer, are not well understood. Cells were grown in matrigel, causing the formation of three-dimensional spheroids modeling the physiological architecture of the oral epithelium. Those spheroids were chronically exposed to vape with different treatment conditions to study the functional …

Narrating The Fragmenting Brain: Alzheimer's Disease Neuronarratives, Bonnie Cross

Electronic Theses and Dissertations, 2020-2023

This dissertation examines the representation of Alzheimer's Disease (AD) neuronarratives (NN), works that centralize the brain or consciousness in the plot, in multiple modalities to support that argument that neuronarratives should be expanded into a transmedia genre. These modalities include neurogames, neurocomics, and neuromemoirs. These three modalities were analyzed to determine how selfhood and social networks are represented by characters or authors with Alzheimer's Disease. As AD is often viewed as the loss of selfhood and is associated with isolation, these works combat these stigmas and complicate representations of the disease. The use of images was also examined in neurogames …

Acute Effects Of Sprint Interval Training And Blood Flow Restriction On Neuromuscular And Muscle Function, David Gonzalez Rojas

Electronic Theses and Dissertations, 2020-2023

The purpose of this investigation was to examine the effects of continuous (CBFR) and intermittent (IBFR) blood flow restriction (BFR) applied during sprint interval training (SIT) on performance, muscle, and neuromuscular function. Fifteen men completed SIT with CBFR, IBFR, and No-BFR. Each SIT bout consisted of 2, 30-s maximal sprints on a cycle ergometer with a resistance of 7.5% of body mass. Concentric peak torque (CPT), maximal voluntary isometric contraction (MVIC) torque, and muscle thickness (MT) were measured before and after the SIT protocols during each visit. During the maximal strength assessments, surface electromyography (sEMG) was recorded and during each …

Exploring Population Structure And Diversity Across Time In Population Of American Flamingos (Phoenicopterus Ruber), Jessica Folsom

Electronic Theses and Dissertations, 2020-2023

Dispersal and connectivity within a population often promotes overall diversity and adaptive potential, therefore a disruption of existing patterns of connectivity by local extinction can have significant consequences for the affected species. However, the extent of these impacts on recovery is not always known. American flamingos (Phoenicopterus ruber) present an ideal opportunity to investigate how changes in gene flow influence within population diversity and genetic structure over the span of a century for a recovering population. Flamingos were highly sought-after by hunters for their meat and feathers, and as a result, the Florida population was extirpated by the beginning of …

Preclinical Assessment Of Psychoplastogens For Treatment Of Psychiatric Symptoms And Neuroplasticity Deficits In Huntington Disease, Nicholas Skiados

Electronic Theses and Dissertations, 2020-2023

Huntington disease (HD) is a neurodegenerative disorder caused by a CAG trinucleotide repeat expansion in the huntingtin (HTT) gene. HD manifests as a triad of psychiatric, cognitive, and motor symptoms, the latter of which defines symptomatic onset of the disease. Psychiatric symptoms including aggression and depression often emerge decades prior to motor symptom onset. Psychiatric disorders are closely linked with dysregulated neural plasticity, the ability of the brain to form new synaptic connections. Neural plasticity is impaired in HD, potentially playing a role in psychiatric symptoms. However, the association between plasticity and psychopathology in HD has yet to be thoroughly …

Investigating Plant Physiological Responses To Global Phylogenetic Diversity Of Glomeromycotina, David Z. Mowbray

Honors Undergraduate Theses

Arbuscular mycorrhizal (AM) fungi are ubiquitous symbionts of terrestrial plant species with associations predominantly characterized as mutualistic. In addition to well-documented enhancement of host growth response, more recent analyses have demonstrated the conferral of host benefits under numerous biotic and abiotic stressors. However, much of the established evidence originates from studies involving limited AM fungal diversity. Accordingly, this study sought to evaluate the potential effects of inoculation on plant host physiological traits within a growth chamber environment, investigate potential correlations between host trait responses, & assess the degree of phylogenetic signal observed in trait responses due to the presence of …

Biomarker Identification For Breast Cancer Types Using Feature Selection And Explainable Ai Methods, David E. La Rosa Giraud

Honors Undergraduate Theses

This paper investigates the impact the LASSO, mRMR, SHAP, and Reinforcement Feature Selection techniques on random forest models for the breast cancer subtypes markers ER, HER2, PR, and TN as well as identifying a small subset of biomarkers that could potentially cause the disease and explain them using explainable AI techniques. This is important because in areas such as healthcare understanding why the model makes a specific decision is important it is a diagnostic of an individual which requires reliable AI. Another contribution is using feature selection methods to identify a small subset of biomarkers capable of predicting if a …

Responses Of A Pine Flatwoods Specialist Treefrog To Prescribed Fire, Ian Biazzo

Electronic Theses and Dissertations, 2020-2023

Coarse outcomes of prescribed fires are well-understood, but fine scale impacts on many assemblages are still unknown. When fire approaches, animals escape to unburned areas, hide in place, or are killed by fire. Treefrogs are unique in their use of trees for most of their adult nonbreeding activities. This reliance on uplands and three-dimensional landscape composition makes them a great model to study prescribed fire impacts. We focused analyses on an upland flatwoods specialist comprising 99% of our captures, the pinewoods treefrog Dryophytes femoralis. We assessed this species' responses to prescribed fire using two separate before-after-control-impact replicated field experiments in …

Role Of Endoplasmic Reticulum Stress Response In Parainfluenza Virus Acute To Persistent Infections, Lauren L. Abbitt

Honors Undergraduate Theses

Persistent viral infections are a major health concern, with persistently infected (PI) cells being a source of continued shedding of virus and generation of viral mutants. Here, we hypothesized that cells persistently infected with the enveloped virus parainfluenza virus 5 (PIV5) would show altered expression of endoplasmic reticulum (ER) stress proteins and increased resistance to death caused by drug-induced ER stress. To test this, lysates of mock-infected, PIV5 acute-infected, and PIV5 PI human lung A549 cells were collected and levels of ER stress proteins were compared. Western blotting revealed that immunoglobulin heavy chain binding protein (BiP/GRP78) was present in higher …

Variation In Genetic Structure And Dispersal Of Juvenile Green Turtles, Gustavo Stahelin

Electronic Theses and Dissertations, 2020-2023

Sea turtles are long-lived, globally distributed animals with a complex life-history. Individuals from different populations often share the same foraging areas (mixed stock aggregations). Understanding patterns of dispersal and connectivity between reproductive populations and mixed stock aggregations is fundamental for the development of effective conservation plans. Recently, green sea turtle (Chelonia mydas) populations in several reproductive areas have increased, providing an opportunity to evaluate how demographic changes in reproductive areas impact dispersal to, and the composition of, mixed stock aggregations. In this dissertation, I evaluated how dispersal from reproductive populations in the Greater Caribbean to mixed stock aggregations may have …

Evolutionary History And Adaptation To Salinity In American Alligators, John Konvalina

Electronic Theses and Dissertations, 2020-2023

Stressful environments can commonly be found at the edge of a species range and may be a driver for adaption in suboptimal environments. Furthermore, the edge of a species' range can expand and contract over time, resulting in multiple independent invasions of the same stressful habitat. Elucidating population genetic structure and demographic history can aid in determining the which geologic factors impact range distributions and when climatic changes occurred driving genetic patterns observed in contemporary populations. Moreover, populations at the edge of the species range may adapt to the stressful environments that occur at the range edge and exhibit genetic …

Refining The Use Of Stable Isotope Analysis In Detecting Wildlife Laundering, Kevin Guilfoyle

Electronic Theses and Dissertations, 2020-2023

The international wildlife trade has caused significant declines in wild populations. Captive breeding can reduce the pressure on wild populations caused by overcollection, but if not properly monitored, wildlife laundering can lead to further population declines. Improving the forensic ability to detect wildlife laundering will assist in monitoring the wildlife trade and enforcing regulations, thereby aiding recovery of wild populations. Stable isotope analysis has grown in importance as a forensic tool, but improvements are needed. Here, stable isotope analysis (δ13C) on eggshells of captive bred and wild sourced island apple snails (Pomacea maculata) distinguished between the two; eggshells of captive …

Host Cell Responses Modulate Oncolytic Viral Treatment Of Neuroblastoma Cells, Kritika Kedarinath

Electronic Theses and Dissertations, 2020-2023

Neuroblastoma is an aggressive pediatric cancer that is poorly responsive to traditional cancer therapies. Oncolytic viral (OV) vectors such as Zika virus (ZIKV) and Parainfluenza virus type 5 (P/V virus) are promising neuroblastoma therapeutics, but the role of innate immune responses in the effectiveness of OV killing is not well understood. Previous studies showed the neuroblastoma cell line SK-N-AS (expressing low CD24) had low permissivity for ZIKV infection, and this restriction was relieved by ectopic CD24 expression (CD24-high cells). Compared to permissive CD24-high cells, the non-permissive CD24-low cells had elevated basal levels of IRF-1, NF?B and phosphorylated STAT1; these cells …

Following Faculty Engaging In Collaborative Action Research To Approach Curricular Change In Undergraduate Biochemistry, Christopher Nix

Electronic Theses and Dissertations, 2020-2023

This study engaged in a curricular redesign of an undergraduate biochemistry course undertaken by a collaborative action research group. The initial portion of this study investigated student conceptual understanding of foundational concepts via a rigorously tested concept inventory. the impact of the redesign on the student foundational conceptual understanding was determined by comparison with a baseline data set. Findings suggest that students enter and exit the biochemistry course with little understanding of key foundational concepts. Examination of student performance after the incorporation of creative exercises showed a significant impact of the curricular changes on two of the concepts of interest. …

Time Of Day Effects On Maximal Effort Strength/Power And Fatigability Assessments, Justine Renziehausen

Electronic Theses and Dissertations, 2020-2023

The circadian rhythm is a 24-hour cycle present within most biological systems that is controlled by the suprachiasmatic nucleus (SCN) of the hypothalamus. The SCN is responsible for synchronizing the peripheral "clocks" present in other tissues so that all rhythms, such as heart rate, body temperature, and hormone secretion, are functioning together. As most systems experience a circadian rhythm, physical performance likely does as well. Previous studies have investigated time of day effects on maximal strength, power, and endurance performance, however, factors (e.g., sex, chronotype, age, etc.) have not clearly been distinguished. Additionally, body temperature has been suggested to be …

Identification And Influence Of Species-Informative 16s Ribosomal Rna Sequences And Evaluation Of Ocean Biofilms, Nikhil Bose

Electronic Theses and Dissertations, 2020-2023

16S ribosomal RNA (rRNA) gene sequences are commonly analyzed for taxonomic and phylogenetic purposes because they contain variable regions that help distinguish genera. However, intra-genus classification is difficult due to high sequence similarity among closely related species. The biological impact of nucleotide variants in 16S variable regions are often unknown and hence their sequence differences are weighted evenly during classification, which provides poor species identity confidence. In this dissertation, I determined that analysis of intra-genus 16S allelic variants can provide species information and that nucleotide changes in 16S rRNA variable regions can impact ribosome quality. In one study, I analyzed …

Behavioral, Morphological And Genetic Differentiation Among Populations Of Enyaliopsis, Laura Macamo

Electronic Theses and Dissertations, 2020-2023

The study of biodiversity is a fundamental part of the study of the ecosystem's function and stability and how changes in the habitat shape the interaction between species. In recent years, the classification of species benefited from the analysis of several types of data to aid the distinction of morphologically similar species. Enyaliopsis iaculator (Naskrecki and Guta, 2019) is a species endemic to central Mozambique. Different populations of E. iaculator were reported to exhibit differences in the time of the day the mating call is displayed, but no morphological differences were reported. Since call behavior tends to be species specific …
