Commodity Thermoplastic Elastomer-Enabled Templated Synthesis Of Large-Pore Ordered Mesoporous Materials, Anthony Griffin, Parker Frame, Yizhi Xiang, Zhe Qiang
Commodity Thermoplastic Elastomer-Enabled Templated Synthesis Of Large-Pore Ordered Mesoporous Materials, Anthony Griffin, Parker Frame, Yizhi Xiang, Zhe Qiang
Faculty Publications
Fabrication of ordered mesoporous materials (OMMs) has predominantly relied on templating-based methods. However, these methods are constrained by several limitations, especially the limited pore sizes attainable with commercially available surfactants used as structure-directing agents. To unlock the full potential of the OMMs, it is essential to develop synthetic strategies that facilitate the production of large-pore OMMs using scalable processes and cost-effective precursors. This work demonstrates the use of thermoplastic elastomer (TPE)-derived carbon replicas for synthesizing ordered mesoporous silica (OMS) and metal oxides (OMMOs) via precursor infiltration and template removal. The nanostructural evolution of the resulting inorganic materials was systematically investigated. …

Gulf and Caribbean Research
The Bahia Grande is a 6,500—acre tidal basin located at the southernmost tip of Texas. Tidal flow into this coastal estuary was cut off in the 1930s, causing the basin to dry up for ~70 y. A pilot channel connecting the Bahia Grande to tidal waters was constructed in 2005, allowing flooding of the basin to occur. Throughout the period reported herein (2005–2019), the system remained characterized by persistent spatial and temporal episodes of extreme hypersalinity (>70)—a critical factor influencing estuarine community composition and driving key ecological processes. With additional rehabilitation actions forthcoming, characterization of the estuary is essential …

Once vibrant ecosystems, coral reefs are degrading at unprecedented rates due to natural and human—induced disturbances, necessitating immediate restoration and conservation efforts. Evaluating the success of these projects often involves assessing changes in reef biodiversity. Bioacoustics has emerged as a promising, non—invasive method for such evaluations, though its efficacy remains debated. This study aimed to determine whether the diurnal soundscapes of restored coral reefs are consistent across different time frames (months) and spatial scales (reefs), which is crucial for developing reliable monitoring tools for reef health. To achieve this, 2 commonly used acoustic indices, the Acoustic Complexity Index (ACI) and …

Use Of Light Traps To Assess The Taxonomy And Seasonality Of Early Life Stages Of Fishes Recruiting To Upper Matagorda Bay In Texas, Polly Hajovsky, Joel Anderson, Damon Williford
Gulf and Caribbean Research
Detecting the ingress of larval and early juvenile fishes into estuaries is crucial for understanding the early life stages and population dynamics of species—specific recruitment seasonality. However, monitoring these early life stages presents challenges due to their small size, seasonal variability, spatial patchiness, and their use of structurally complex habitats. Although plankton nets have been widely used to sample larval fishes, light traps have been found to have more flexibility, durability, and cost—effective. This study aimed to assess the effectiveness of light traps for sampling larval and early juvenile fishes in a Texas estuary. The objectives of this study were …
The Effects Of A River Closure On A Snook (Centropomus Spp.) Nursery Community In The Rio Grande River, Texas, Ethan Getz, Perry Trial, Catherine Eckert, Joel Anderson
The Effects Of A River Closure On A Snook (Centropomus Spp.) Nursery Community In The Rio Grande River, Texas, Ethan Getz, Perry Trial, Catherine Eckert, Joel Anderson
Gulf and Caribbean Research
Snook (Centropomus spp.) support important fisheries in the Gulf of Mexico and populations are increasing in Texas. However, a primary snook nursery, the Rio Grande River, remains one of the most imperiled rivers in North America. In 2001—2002, low flows led to the formation of a sandbar and the complete blockage of the Rio Grande, eliminating exchange with coastal waters. Here, data collected by the Texas Parks and Wildlife Department were used to determine how the Rio Grande closure affected juvenile and subadult snook and the estuarine community. Seine and trawl samples were collected prior to (1992—1997) and during …

The Macroalgal Composition Differs Among Depths And Zones In Cuban Mesophotic Coral Reef Eosystems, Beatriz Martínez-Daranas, Dennis Hanisak, Partricia M. González-Sánchez, Stephanie Farrington, John K. Reed
Gulf and Caribbean Research
Previously the algal community of Cuban mesophotic coral reef ecosystems (MCEs) has not been characterized quantitatively. The objective of this study was to explore the distribution of macroalgae around Cuba and their depth profiles within the mesophotic zone (30−150 m). Data on the algal community were obtained in 2017 during 43 ROV (remotely operated vehicle) dives around Cuba’s shelf. Scientists specializing in algal taxonomy watched the live ROV video on board the ship and recorded algal presence every ~5—10 min in a database. Algae were identified to the lowest possible taxa, and algal presence/absence was analyzed in 20 m depth …

Early Season Tropical Cyclones Affect Birds Breeding On A Barrier Island, Theodore J. Zenzal Jr., Amanda N. Anderson, Brock Geary, Jessica Schulz, Robert C. Dobbs, Wylie C. Barrow Jr., James H. Waddle
Gulf and Caribbean Research
Animal populations often experience acute natural disturbances, most of which are connected to short—term weather events. Occurrences of early—season tropical cyclones during the peak of the avian breeding season are likely to increase with climate change, which can substantially impact populations of coastal breeding birds at multiple scales. To understand the acute impacts of severe tropical cyclones, we investigated how abundances of breeding birds changed before and after 4 early season named tropical cyclones on a barrier island in the Gulf of Mexico. We detected a change in pre— versus post—storm numbers of breeding birds after 2 out of 4 …

3d-Printed Polylactide Structures Do Not Affect The Demography Of The Threatened Coral Acropora Cervicornis, Gabriela Baerga-Jiménez, Alex E. Mercado-Molina
Gulf and Caribbean Research
The development of artificial structures using emerging 3D printing technology has been proposed as a possible strategy to promote the recovery of degraded coral reef ecosystems. Current technologies allow 3D printers to faithfully replicate the morphology of coral reef attributes (e.g., substrate and coral colonies). Thus, 3D printing can be used to create artificial structures that replicate microhabitats resembling those found by reef organisms in nature. However, the use of 3D printing technology for reef conservation and restoration purposes is still in its early developmental stages. Consequently, the potential benefits or detriments of the technology on coral reef health and …

Elucidating The Mechanism Of Interleukin-17a Signaling In The Pathogenesis Of West Nile Virus, Farzana Nazneen
Elucidating The Mechanism Of Interleukin-17a Signaling In The Pathogenesis Of West Nile Virus, Farzana Nazneen
Dissertations
West Nile Virus (WNV), a neurotropic flavivirus transmitted by mosquitoes, is a leading cause of viral encephalitis in the United States and remains a significant public health concern. Unfortunately, no vaccine or therapeutic intervention is available against WNV infection. Previous studies, including ours, demonstrated that interleukin-17A (IL-17A) signaling increases the cytotoxic potential of CD8+ T cells to facilitate WNV and parasite clearance; however, the molecular mechanism is not understood. IL-17 receptor C (IL-17RC) is an obligatory co-receptor with IL-17 receptor A (IL-17RA) for signaling induced by IL-17A, IL-17A/F, and IL-17F. In this study, we found that IL-17RC deficient ( …

Investigating Nekton Response To Changing Salinities In The Mississippi Sound: An Experimental And Statistical Approach, Adam Murray
Master's Theses
The Mississippi Sound provides nursery habitats for many coastal species and is recognized for its commercial fisheries. Previous freshening events linked to the Bonnet Carré Spillway, a Mississippi River flood diversion structure, proved catastrophic for oyster populations in the Mississippi Sound, but effects on mobile fish and shellfish species are not well-defined. The planned Mid-Breton Sediment Diversion (MBSD), an initiative to combat wetland loss, is also forecasted to lower salinities in the region, increasing the need to better understand responses of commercially and ecologically important species to freshening events. The objective of this study was to characterize effects of salinity …

Geomorphic Assessment And Flow Modeling Of Pearl Darter (Percina Aurora) Habitat In The Pascagoula River Watershed, Malia Davidson
Master's Theses
Freshwater ecosystems are complex ecosystems driven by hydrologic, geomorphic, and biological processes. Considering both abiotic and biotic factors is important to understanding resident species habitat. Geomorphology is a known, but often neglected factor in habitat assessment for freshwater fishes. A crucial feature commonly seen in alluvial stream systems are sandbars, which are dynamic and variable sediment structures that are known to have many associated species. One such species is the Pearl Darter, Percina aurora, a federally threatened species that only resides in the Pascagoula River watershed. Despite its status, habitat preference remains unclear. To fill this knowledge gap, I …
Lack Of Inflammatory Response In Mouse Embryonic Cells To Listeria Infection, Damilola Oyebode
Lack Of Inflammatory Response In Mouse Embryonic Cells To Listeria Infection, Damilola Oyebode
Master's Theses
Approximately 1 in 5 pregnancies in the United States results in miscarriage, with a significant percentage of these losses attributed to failed implantation due to immunological challenges encountered by the early embryo. Recent research has shown that key cell types within mouse blastocysts, including embryonic stem cells (ESCs) and trophoblast stem cells (TSCs), exhibit remarkable resilience against the cytotoxic effects associated with viral infections and embryotoxic cytokines, such as TNFα and IFNγ, both of which are known to hinder blastocyst development. However, the immune properties of the preimplantation stage embryo, specifically the blastocyst, remain poorly understood. Using mouse cell model, …
Juvenile And Subadult Gulf Sturgeon (Acipenser Desotoi) Use Of The Pascagoula River Estuary, Sarah Stovall
Juvenile And Subadult Gulf Sturgeon (Acipenser Desotoi) Use Of The Pascagoula River Estuary, Sarah Stovall
Master's Theses
Gulf Sturgeon (GS) are an anadromous species currently listed as “Threatened” under the Endangered Species Act. They reside in habitats across the northern Gulf of Mexico including coastal rivers, estuaries, and marine waters, making annual migrations between freshwater and marine habitats for spawning/summer resting and feeding, respectively. Since past studies prioritize adult movement, understanding how and when juvenile and subadult GS use the Pascagoula River estuary (PRE), a complex, bifurcated river delta federally designated as critical habitat is necessary to improve conservation efforts. My thesis assessed juvenile and subadult GS use of the PRE across four years (2020-2024) by analyzing …

Advances In Biomedical Research And Treatments: What Is Acceptable?, Michael L. Clancy, Khalid M. Iskandarani, Mitchell C. Mccrea
Journal of Health Ethics
This study investigated the technology acceptance (TA) of twenty-first century biomedical treatments by adults in the United States. A new TA instrument was created, using five distinct levels: (1) Healing and Prevention, (2) Replacement Organs, (3) Enhancements-Medical, (4) Enhancements-Discretionary, and (5) Transhumans. An on-line survey produced 353 usable responses, which showed distinct patterns for each of five biomedical treatment levels. There was clear support for Levels 1–3, but very strong opposition to Levels 4–5. The TA finding draws the line between which human interventions are acceptable versus others that should be prohibited through public policies and medical guidelines.

The main objective of this thesis was to identify potential new pond sites across southern Mississippi for the critically endangered dusky gopher frog (DGF). Ephemeral ponds are the preferred breeding habitat for the species, but they are quite rare in the region due to the diminishment of the longleaf pine ecosystem. This research addresses gaps in the current literature by providing a broad overview of dusky gopher frog breeding habitat identification. LiDAR derived datasets as well as tools within ArcGIS Pro were utilized in order to perform spatial analysis on sites of interest in south Mississippi. By using this methodology …
Assessing The Impacts Of Grazing By Piney Woods Cattle And Controlled Burning On The Herbaceous Layer In An East Gulf Coastal Plain Longleaf Pine Woodland, William Mcfarland
Assessing The Impacts Of Grazing By Piney Woods Cattle And Controlled Burning On The Herbaceous Layer In An East Gulf Coastal Plain Longleaf Pine Woodland, William Mcfarland
Master's Theses
Fire and grazing are two disturbances which influence vegetation composition and diversity in many ecosystems. In the southeastern United States, longleaf pine plant communities are adapted to frequent fires and are likely to have been grazed by bison in the past. Though bison have been extirpated from this region, Pineywoods Cattle, which were introduced by the Spanish in the 16th Century, have been fulfilling a similar role in many of these communities. This study examines the effects that combined grazing and controlled burning have on plant diversity, biomass, and community similarity in a longleaf pine savanna in the East …

Investigating The Response Of The Eastern Oyster (Crassostrea Virginica) To Low Dissolved Oxygen Conditions, Abiola Obafemi
Master's Theses
The Eastern oyster (Crassostrea virginica) requires dissolved oxygen (DO) of about 4 mg/L to support proper physiological function. Hypoxia and/or microxia occur when DO decreases to ≤ 2 mg/L. Salinity and temperature changes resulting from large-scale freshwater influx have been identified as key factors influencing the oyster populations in the Mississippi Sound. It is important to investigate the impacts of DO conditions on oyster mortality, biomass, size, and condition during these freshening events. Under controlled laboratory experiments, this thesis investigated 1) the response of oysters to microxic, hypoxic, and normoxic conditions 2) the response of oysters to combined hypoxia and …
Projected Range Shift Of The Atlantic Surfclam, Spisula Solidissima, And The Ocean Quahog, Arctica Islandica, Under Climate-Induced Benthic Warming: Forecasting Fishery Influence In The Mid-Atlantic Bight Throughout The 21st Century, Molly Mae Spencer

Oyster larval microbiomes are shaped by their aquatic microbiomes. Understanding the dynamics of and the factors shaping RAS microbiome may provide insights to how the microbiome can be a tool for optimizing larval production. This study’s goals were to investigate the microbiome stability of a RAS rearing oyster larvae across time and space, determine impacts of larval presence on the microbiome, and examine connections between larvae production outcomes and microbiome stability. Water samples were collected weekly from …
Impact Of Thermal-Hydric Stress Of Physiological Performance And Mating Behavior Of Fiddler Crabs, Talene G. Yeghissian
Impact Of Thermal-Hydric Stress Of Physiological Performance And Mating Behavior Of Fiddler Crabs, Talene G. Yeghissian
Dissertations
Fiddler crabs live on the edge of their thermal tolerance limits, balancing the need to thermoregulate with the need to mate. Previous research suggests that increased temperature reduces fiddler crab surface activity time, thus decreasing mating opportunities, throughout the range species with greatest impacts to low latitude populations. The less studied missed mating opportunities associated with behavioral compensation for thermal stress are crucial to understanding species vulnerability to climate change. In this dissertation, I describe a combination of experimental and observational approaches in the field and in the laboratory to investigate the physiological and behavioral responses of fiddler crabs to …
