Loggerhead Sea Turtle (Caretta Caretta) Nesting Experience, Seasonal Variation, And Hatching Success On A Georgia Barrier Island, Luke Sundquist

College of Graduate Studies: Theses & Dissertations

Loggerhead sea turtles nest commonly on the Georgia barrier islands and serve critical roles in human cultures, coastal economies, and multiple ecosystems. However, their global populations are declining and dependent on conservation efforts and informed management of natural and anthropogenic threats. Nesting offers a unique opportunity to research and protect this valuable marine species in terrestrial habitats. Microsatellite DNA sampling from eggshells can consistently identify nesting females from eggshells, allowing tracking of nesting behaviors for large populations over multiple years. Using this novel technology, we compared maternal investment and nest site-selection between first-time nesting neophytes and experienced remigrants. We sampled …

Medical Providers' Use Of Maternal Mental Health Screening Tools During Prenatal Appointments In Southeast Georgia, Andreka Ewing

College of Graduate Studies: Theses & Dissertations

In the United States, maternal mental health disorders are the most common comorbidities experienced during pregnancy and after childbirth.

Investigating Salinity Intrusion Effects On Sapelo Island, Georgia Using Benthic Macroinvertebrate Bioindicators, Raymond Paul Kidder Ii

College of Graduate Studies: Theses & Dissertations

Coastal wetlands are threatened by the compounding effects of sea level rise and historical land modification. Historically, much of Sapelo Island, Georgia was deforested and drained using a series of ditches and canals to create arable land fit for agriculture and to provide drainage to the inhabited parts of the island. Today, this network of artificial channels is believed to be facilitating the movement of saltwater from the nearby estuary into freshwater areas on the interior of the island. This study aimed to better understand the frequency and magnitude of salinity intrusion events along with their resulting impacts to the …

Spatial Drivers Of Freshwater Fish Biodiversity, Community Structure, And Diet Composition Across Georgia, Usa, Patrick Lewis

College of Graduate Studies: Theses & Dissertations

The geographic complexity of the Southeastern United States, in particular Georgia, is evident in the diversity of stream habitats present throughout that host unique stream fish communities but is threatened by anthropogenic activity. This spatial complexity can be captured through the ecoregion framework, which delineates areas of distinct habitat. However, this differing habitat character between ecoregions leads to different environmental pressures that may promote species heterogeneity between communities, may create intraspecific niche diversity in widely distributed species, and may complicate the transferability of widely accepted theoretical models of fish ecology between them. I analyzed a long-term fish community dataset, examining …

Investigation Of Additives And Ingredients Of Bio-Resin For Visible Wavelength Laser-Induced Polymerization, Patrick Riggs

College of Graduate Studies: Theses & Dissertations

Optical 3D printing is a branch of Additive manufacturing (AM) that utilizes low-waste production leading to efficient and rapid prototyping. Currently, this method of AM is associated with mainly petroleum-based resins. Bio-resin polymerization is an emerging research area for finding replacements for petroleum-based resins, but curing the resin with laser energy is not normally a practical use case. Current optical 3D printing uses lasers to cure liquid resins to form solid 3D objects in a layer-by-layer process which is time consuming, defect prone, and a leading limiting factor for high volume production; so, finding a way to incorporate bio-resin into …

Dna Methylation And The Response To Infection In Introduced House Sparrows, Melanie Gibson

College of Graduate Studies: Theses & Dissertations

Epigenetics is the study of molecular modification of a genome without changing its base pairs. The most studied type of epigenetic mechanism is DNA methylation, which is capable of turning a gene “on” or “off.” Epigenetic potential is the capacity to which an individual can have methylation on its genome. The more CpGs available, the greater the epigenetic potential. In invasive species, genetic variation has been observed to be paradoxical: not much of it exists on a genomic level, but epigenetically, phenotypic variation can occur. The focus on shift in gene expression in this study is on Toll-Like Receptor 4 …

Understanding The Feasibility Of Improving Interfacial Properties In Direct Ink Writing Of Silicone-Polyurethane Resin Hybrid Material, Ayobami Samuel Akinfenwa

College of Graduate Studies: Theses & Dissertations

The progress in materials engineering and the ability to make various models possible have made soft robotics a popular alternative to traditional robotics. Still, soft robots need various parts, like Printed Circuit Boards (PCBs), batteries, cables, fittings, and more, to work correctly or to get attached to other complex parts. These parts can have different material properties, like elastic moduli, strength, etc. Because of these differences, mechanical failures happen at the points where two materials meet, making soft robots less durable and less lasting in real-life situations due to failure. Conventionally, the fabrication of soft robot parts is through moulding. …

Child Sexual Abuse Cases In The Catholic Church Vs. Secular Groups: A Media Content Analysis, Hannah G. Adkison

College of Graduate Studies: Theses & Dissertations

Child sexual abuse (CSA) is a serious public health problem in the United States, with estimates suggesting that approximately 8% of males and 20% of females experience some form of sexual violence before adulthood (Pereda et al., 2009). Adult acquaintance victim-offender relationships account for 83% of all cases (Ullman, 2001). And while the acquaintance of victim- offender relationships is facilitated by a range of social institutions, perhaps none have received as much media attention as those occurring in the context of the Catholic Church (Formicola, 2014).
