Effectiveness and Efficiency of UV-C Lights at Killing Bacteria:

Bacteria lie on surfaces all around us, resulting in a desire to clean or disinfect them to avoid the adverse effects of bacteria. One popular method is UV-C light, which has a wavelength of 200-280 nanometers. This study aimed to determine the effectiveness of UV-C lights in killing bacteria. Tests were conducted using a power sensor and bacterial lawns to determine the impacts of different variables on the effectiveness of UV-C lights. Testing measures were taken to ensure that all data was collected independently and identically. It was found that height, surface placement under UV-C lights, electrical power to lights, and reflectivity had the most significant impact on the effectiveness of the light. When optimizing these variables, it was found that with three and two lights there was a substantial bacteria kill rate once the exposure exceeded 3 seconds. This study has proven that UV-C is an effective and efficient way to kill bacteria on surfaces.

This project delved into the multifaceted world of blacksmithing, merging scientific inquiry with traditional craftsmanship to understand the nuances of metal work and material sciences. The primary objective was to immerse in the practicality of the craft, with the intent of learning the use of essential tools, the operational aspects of a forge, and further developing my knowledge of material properties of metals. In the aspect of material properties, a target was made to cultivate a comprehensive understanding of the manipulation of metal properties, utilizing heat treatment, cooling, and knowledge of metallurgical behavior.

Key milestones were set, including the acquisition of competencies in manipulating metal through heating, working, and cooling to craft rudimentary objects like hooks and nails, progressing towards more intricate creations such as knives and ornamental ironworks. The project's methodology was twofold: an investigative theoretical approach entailing the study of literature and visual resources to build a foundational knowledge base, and an empirical approach through active participation in local blacksmithing workshops.

The culmination of the project saw the successful completion of a functional coat rack and a knife forged from a railroad spike, reflecting both the learned techniques, material science, and personal creative expression. The analytical engagement with metals and forging methods paved the way for producing personalized, high-quality metalworks. The endeavor not only honed a distinctive skillset but also unveiled the potential for a post-graduate entrepreneurial venture specializing in custom-made tools and decorative arts, thereby intertwining the art of blacksmithing with contemporary business opportunities.

Urban trees provide a variety of ecosystem services to an area that allows both humans and animals to thrive in their vicinity. The ecosystem services provided are able to be determined through specific aspects of a tree and their location in relation to buildings and ground cover. These ecosystem services include carbon sequestration, air quality improvement, avoided runoff, and energy effects. Texas Christian University (TCU) was designated a tree campus by the Arbor Day Foundation meaning they commit to making sure that they are planting and preserving the trees that are in their care. This study’s purpose was to determine the ecosystem services provided by the trees in TCU’s care, including the costs of each tree and the services that they provide. By surveying the diameter at breast height (DBH), total height, crown base height, species, crown health and exposure, canopy size, ground cover, and health we are able to determine what services are being provided by the TCU trees. Determining the services is possible through the service iTree Eco where the data was inputted allowing its use in the estimation of the services that the trees provide.

As of the year 2022, over half of the world’s population lives in cities.​ Large-scale movement into urban environments has inevitable effects on the urban landscape, and in turn has negative effects on the environment. Central Texas is home to the state’s capital city of Austin. With the Colorado river running though the city and an estimated 300 days of sunshine a year, Austin has become a hotspot for urban growth ​.​ Since the 2020 census, Austin’s population has increased by 12,547 residents, with a growth rate of 1.3%, making Austin the 10th largest city in the country. The greater metropolitan Austin area gained nearly 63,000 residents between the years of 2021 and 2022​. In the face of tree removal due to development and climate hazards, cities are losing vital ecosystem services provided by urban forests. For this project, I will be studying how tree removal in the city of Austin affects Land Surface Temperature (LST). The purpose of this research is to examine the influence of tree removal on urban heat. Given the importance of trees to human health in highly urbanized areas, understanding how forest loss impacts urban heat and affect local microclimates will help urban planners, foresters, developers, and municipalities implement sustainable urban forest programs to safeguard human health. By exploring the relationship between urban deforestation and heat, this research contributes to the growing body of literature on urban forests and microclimates and provides information to support the conservation of urban trees.

Location: Second Floor, Table 8, Position 1, 1:45-3:45

Urbanization disrupts local climates by replacing natural land cover with impervious surfaces. These surfaces such as concrete and asphalt retain more heat than vegetated cover, therefore, putting these areas at risk for the urban heat island effect. This is when urban areas become significantly hotter than outlying areas and exhibit high temperature anomalies, therefore, putting its residents at risk. Another contributing factor is anthropogenic emissions of greenhouse gases from industries and automobiles. The purpose of this research is to assess areas vulnerable to the urban heat island effect in Dallas County, Texas by looking at the heat severity index (The Trust for Public Lands) and land cover data (NLCD 2021). This study aims to provide insights for planning and policies that enhance resilience to urban heat island risks in Dallas County.

PERCEPTIONS OF CONSERVATION EDUCATORS ON PROGRAM EFFECTIVENESS: A MIXED METHODS STUDY

Location: Third Floor, Table 9, Position 1, 1:45-3:45

Environmental education is gaining popularity and recognition as a critical strategy to reduce environmental harm, biodiversity loss, and habitat degradation. Education has been identified as a top factor contributing to people’s willingness to engage in environmentally positive conservation behaviors. Non-formal learning institutions such as zoos and aquariums have the unique ability to create and engage learned in species specific education programming. Species-specific education programs can generate high public appeal and contribute to overall environmental conservation outcomes. Research on nonformal environmental education is limited, but most often reports that short-term or single experiences may not be successful in increasing knowledge or contributing to behavior changes. The purpose of this research is to assess the perceptions of educators at non-formal institutions about the success of their conservation education programs. To do this, we conducted a mixed-methods study with educators at marine conservation centers to report on their perceived strengths, weaknesses, opportunities, and threats of education programming as well as on how they define and measure their program success. Our results revealed that educators believe their short-term education programs can be impactful and report on the factors that must be considered to maximize successful program outcomes.

Across the U.S. there are 1335 Superfund sites that range from abandoned mines to old military bases that pose serious risk to the public if not remediated properly. The Tar Creek Superfund site, located in Picher, OK, is one example which could contaminate downstream water supplies via contaminated water and sediment due to the heavy metals, such as Cd and Pb, left behind from the mining activities. This study seeks to determine if the ongoing remediation is effective at Tar Creek which is located within the Tar Creek Superfund site, and whether contaminated sediment is migrating downstream through the watershed.

The Human Impact on Deer: Integrating Spatial Analysis technology to help sustain White-Tailed Deer populations in the Southern United States

Type: Undergraduate
Author(s): Jackson Galloway Environmental Sciences
Advisor(s): Esayas Gebremichael Geological Sciences

Whitetail-tailed deer (Odocoileus virginianus) are a crucial component of the Southern United States Ecosystem. 5.5 million deer live in the southern regions of the country, and all are impacted by human activity. Hunting and suburban development have created a rift on the species population distribution. This study is aimed at investigating the impact of creating suburban communities and hunting practices in the Southern regions of the United States. Establishing sustainable habitats for white-tailed deer populations using spatial analysis techniques will allow for populations to remain stable. Implementing strategies for property owners and public land attendants to tend for vegetation growth and clean water sources will be crucial for the species' ability to thrive. The objective is to create a distribution map of the white-tailed deer population throughout the southern regions of the United States on data collected from the variability of the land and the physical soil composition for potential vegetation growth.

Location: Basement, Table 5, Position 1, 1:45-3:45

Urbanization refers to the process of converting natural habitats into human-friendly areas, consisting of concrete structures like buildings and roads that are not typically conducive to wildlife. Despite this, many animals, including bats, are able to adapt to urban landscapes and even provide crucial ecosystem services. Bats, in particular, play a vital role in controlling pests in both agricultural and urban areas. Thus, it is imperative to understand the factors that affect their foraging activity. The aim of this project is to identify potential survey sites that can provide insight into the factors that influence prey availability and abundance.

Investigating Bat Drinking Activity in Response to Variability in Water Surface Area

With species facing extinction due to human-induced disturbances, conservation efforts aim to protect wildlife and ecosystems. Urban areas, despite their modifications, can provide essential ecosystem services and support biodiversity. However, ensuring wildlife presence requires understanding resource availability and accessibility. Accessibility, defined by an individual's ability to locate and utilize resources, is influenced by landscape features such as permeability and connectivity, which can impede movement. Species-specific traits, including ecology and mode of locomotion, also play significant roles in resource access. For instance, volant species like birds and bats rely on flight to forage and drink, with their ability to maneuver affecting whether they can access a water source or not. Moreover, access may not only be dependent on the size of a water source but also by clutter (i.e., vegetation, exposed rocks and litter), which can reduce the amount of surface area that is actually available. Additionally, seasonal variations in precipitation and evapotranspiration rates can alter water levels, affecting both the size of the water source and the amount of clutter (i.e., exposing more rocks and enabling more aquatic vegetation to grow). Understanding the spatial and temporal dynamics of water surface area is crucial for effective resource management aimed at making urban environments more suitable for wildlife. Thus, we investigated the influence of variation in water surface area on bat drinking activity in an urban environment. Our study focused on six water sources in Tarrant County, Texas, using drone surveillance, thermal technology, and acoustic monitoring from March to September 2023. We hypothesized that as surface area decreased during summer, bat drinking activity would decline. By addressing one potential aspect of water resource availability and accessibility, our study contributes to to more accurate assessments of urban water resource availability and the development of sustainable conservation practices for wildlife.

Assessing Urban Wildlife Water Availability: Investigating Runoff and Evaporation Dynamics in Fort Worth Ponds

Type: Graduate
Author(s): Peyton Harper Environmental Sciences
Advisor(s): Esayas Gebremichael Geological Sciences
Location: Basement, Table 3, Position 3, 11:30-1:30

Water is an essential resource for urban wildlife, but this water needs to be available and accessible. Fort Worth is an urban area that gets hot and dry during the summer months which can cause many water sources to dry up, making them unavailable for wildlife. However, some water sources in Fort Worth may be more susceptible to drying up than others. This may be affected by runoff which in turn can be a function of different variables such as soil type, impervious surface cover, vegetation cover, elevation, and more. Additionally, differences in location-specific weather may affect evaporation rates of bodies of water. This study aims: (1) to determine the variations in six different pond sites across Fort Worth, (2) to identify the factors that potentially affect runoff and evaporation, and correlate the variables with the rate of changes of the ponds to determine their significance, and (3) use this established relationship to evaluate the susceptibility of other ponds in the area to drying up during summers.

COASTAL EROSION: INTEGRATING GEOSPATIAL TECHNOLOGY TO AID IN THE MANAGEMENT OF EROSION DUE TO RISING SEA LEVELS ALONG US COASTLINES

Advisor(s): Esayas Gebremichael Environmental Sciences
Location: Second Floor, Table 4, Position 1, 1:45-3:45

Along the coastlines of America, specifically along the Pacific Coast and the Gulf of Mexico, rising sea levels are causing great levels of coastal erosion, leading to the loss of coastal homes and ecologically valuable land. Climate change affects the rate at which sea levels rise, which in turn determines how quickly coastlines are eroded. The objective is to analyze coastal maps of California and the Gulf of Mexico to determine which coastal factors facilitate or hinder the degradation of coastlines.

Sustainability Progress of Global Companies Using GRI Standards

Location: Third Floor, Table 5, Position 3, 11:30-1:30

In a recent survey by IBM, 51% of respondents from 10 major global economies stated that sustainability is more important to them today than it was 12 months ago (Emeritus, 2022). Historically, influential corporations have disregarded the triple bottom line and have ignored the effects their supply chains have on the environment, people, and the economy, and in turn, made negative contributions to sustainable development. To reduce and eventually eliminate the harm, many companies are now creating sustainability plans to monitor their progress. Sustainability planning and reporting have gained traction in the last decade given the push for standardization, the need for transparency from consumers, and improved environmental social governance metrics within their business operations. Today, there are over 600 different sustainability reporting standards, industry initiatives, frameworks, and guidelines that have improved the transparency, consistency, and interoperability of sustainable practices (Brightest, 2024). One of the most widely adopted frameworks is the Global Reporting Initiative (GRI). GRI created the first global sustainability and social impact measurement standards in 1997, and they help businesses and other organizations take responsibility for their impacts, by providing them with a global common language to communicate those impacts (Global Reporting Organization, n.d.).

The purpose of this research is to examine the contents of 10 sustainability reports across five industries and document their actions towards sustainable development. I will focus on how companies are not only reducing their environmental impacts but also protecting workers and contributing to society. Understanding the degree to which companies are addressing these challenges is crucial to measuring their progress and determining if they are advancing toward sustainability.

Analyzing the calls a bat emits is one of the main ways to identify a species. We use bat acoustic detectors to filter these ultrasonic sounds produced. As technology advances, so do these detectors. Wildlife Acoustics Inc. produces bat acoustic detectors constantly. These detectors are then tested with older models to see if they produce the same results. We, therefore, conducted a study to test the next generation of bat acoustic detectors to the older models by Wildlife Acoustics Inc. We tested all three detectors at the same site, over the same period, and analyzed the results to see if the newest model was. This study took place in the flight room on Texas Christian University's campus between the dates of 03/01 - 03/08/2024, in Fort Worth Texas.

An Assessment of the Connectivity of Parks as Pollinator Habitats in Tarrant County, Texas at Multiple Spatial Scales

Type: Graduate
Author(s): Maddie Rzucidlo Environmental Sciences
Advisor(s): Brendan Lavy Environmental Sciences
Location: Basement, Table 10, Position 2, 11:30-1:30

Pollinators are essential to the functioning of terrestrial ecosystems. Approximately 87.5% of flowering plants rely on animal pollination for reproduction (Ollerton, 2017) Due to this, pollinators are vital to the production of human consumed crops and the health of ecosystems. Urbanization drives decreases in pollinator biodiversity, species richness and abundance due to loss of habitat and fragmentation (Turo et al., 2021). Urban characteristics such as densification and impervious surfaces can cause pollinator declines and loss of pollinator services (Wenzel et al., 2020).

Tarrant County has a population of 2,110,640 and encompasses 865.2 square miles in of land north central Texas (United States Census Bureau, 2020). It is also the 15th-most populated county in the United States (United States Census Bureau, 2024). Tarrant County is also located in a major pollinator migratory pathway (National Park Service, 2019). Studies show that both population density and city size impact pollinator populations (Norton et al., 2016; Sivakoff et al., 2018). Such rapid population growth has the potential to impact pollinators and their habitats. Urban green spaces such as parks can be beneficial pollinator refuges (Serret et al., 2022). Connectivity of pollinator habitats is important for species richness and abundance (Graffigna et al., 2023). Due to the rapid population growth, land use change, and densification occurring within Tarrant County and the existence of major pollinator habitats within the area, Tarrant County parks are a compelling place to conduct landscape connectivity research on pollinators. The objective of this project is to assess the connectivity of pollinator habitats in the highly urbanized Tarrant County area. This project strives to understand how urban parks as pollinator habitats connect to one another at a range of distances for pollinator travel.

Austin's Walkability: Tree Canopy Cover of Downtown Austin's Sidewalks

As the Capital of Texas, Austin has been a great exemplar in the protection and preservation of trees within their city limits. Austin has had a commitment to these trees for decades, but what do the trees do for the city of Austin? This poster focuses on the sidewalks of downtown Austin, and what percentage of them are covered by the canopy of these trees. Using Geographic Information Systems (GIS) we calculate the percentage of the canopy cover overlaying the sidewalks. Understanding the canopy cover allows us to also find the walkability score of downtown Austin. A tree's canopy provides shade, and when placed over a sidewalk, it provides an escape from the omnipresent heat in Austin in the Texas summers. People in areas of lower-socioeconomic status tend to have reduced trees (and greenspace in general) compared to those of a higher-socioeconomic status. By determining an area's walkability score, we can also find areas of desire where greenspaces and trees can benefit the people living there.

Author(s): Abi Welch Environmental Sciences
Advisor(s): Victoria Bennett Environmental Sciences
Location: Third Floor, Table 8, Position 1, 1:45-3:45

The use of roost sites by multiple bat species is well-documented, especially in large structures where different species are partitioned by distinct microclimates within these structures; however, there is limited research on smaller roost sites, especially artificial ones, such as wooden bat houses. With such houses recommended to improve urban areas for bats or mitigation to replace natural roosts lost during construction projects, understanding species-specific roost use is imperative to ensure these conservation strategies are effective. To address this need, we compared the temporal and spatial use of an artificial roost site by bats in a residential neighborhood in Fort Worth, Texas. Since 2017, we have monitored species presence, including the evening bat (Nycticeius humeralis) known to roost in natural roost sites such as the tree hollows, broken branches, peeling bark, and under thick-stemmed ivy, and the Mexican free-tailed bat (Tadarida brasiliensis), which tends to roost in caves. In addition, we monitored this roost site almost weekly for a year from 2023-2024 to determine how seasonal use in the abundance of these species varied. More specifically, we addressed whether these species displayed year-round communal roosting or species-specific roost partitioning, as well as species-specific seasonal roost use. Along with providing insights into artificial roost use by bats, this study represents the first to demonstrate multispecies use of a roost site, natural or artificial, by evening and Mexican free-tailed bats. The findings have implications for understanding interspecies competition and artificial roost use and therefore contribute to bat conservation.

Using GIS to Determine Emergency Department and Treatment Center Proximity to Opioid Hot Spots in Tarrant County

Type: Graduate
Author(s): Naomi Alanis Interdisciplinary
Advisor(s): Esayas Gebremichael Geological Sciences
Location: Basement, Table 1, Position 2, 11:30-1:30

As opioid overdose deaths in the United States (US) continue to increase, there is an emergent need to treat those with opioid use disorder (OUD). Understanding geographic variations and their impact on different population groups in the US is now more essential than ever. Significant surges in the usage and misuse of street drugs such as heroin and fentanyl, followed by a corresponding increase in opioid-related deaths, have heightened the urgency for this understanding.

Although characteristics of US counties with persistently high rates of opioid overdose mortality and low capacity to deliver OUD medications has been identified, the counties were aggregated into regions within the US and no one specific county has been targeted. Having comprehensive data on OUD prevalence rates across Tarrant County and/or Texas would be beneficial. Current research regarding spatial associations between place features, neighborhood-level social determinants of health measures, and drug overdose deaths is limited in the realm of drug use and opioid overdose fatalities. Recognizing high-risk areas and features (hot spots) could potentially enhance the quality of the emergency department response, harm reduction services, and the precision of treatment and prevention strategies.

Identifying hot spots of opioid-related emergency needs within Tarrant County may help [re]distribute existing resources efficiently, empower community and Emergency Department (ED) based physicians to advocate for their patients, and serve as a catalyst for partnerships between John Peter Smith Hospital System (JPS) and local community groups. More broadly, this analysis may demonstrate that EDs can use geospatial analysis to address the emergency and longer-term health needs of the communities they are designed to serve.

The goal of this project is to 1) identify spatial associations between place features, neighborhood-level social determinants of health measures, and opioid drug overdose deaths (i.e., high-risk/hot spot areas) and 2) compare them to access to treatment providers (i.e., emergency departments, emergency services, and harm reduction services) to identify geographic areas where the two are not well matched.

Assessing Urban Heat Island Intensity Using Landsat Data

Location: Basement, Table 6, Position 3, 11:30-1:30

The escalating impacts of urbanization on local climate patterns, particularly the phenomenon of Urban Heat Islands (UHIs), necessitate effective monitoring and assessment strategies. This project endeavors to evaluate the Urban Heat Island intensity in Houston, Texas, employing Landsat satellite data and Geographic Information System (GIS) tools within the ArcGIS Pro platform. The study integrates multi-temporal Landsat imagery to derive land surface temperature patterns, facilitating a comprehensive analysis of UHI dynamics over time. Spatial analytics and geospatial techniques are employed to assess the correlation between land use/land cover changes and UHI intensity, offering insights into the factors influencing urban heat dynamics. The results are expected to contribute valuable insights for urban planners and policymakers, aiding in the development of strategies to mitigate the adverse effects of UHI and enhance overall urban sustainability. Additionally, the methodology established in this project can serve as a template for assessing UHI in other urban areas, fostering a broader understanding of the urban climate dynamics.

Sedimentation & Subsurface Characterization of the Lower Cretaceous Muddy Sandstone & Upper Cretaceous Mowry Shale, Powder River Basin, Wyoming

Type: Graduate

Advisor(s): Xiangyang Xie Geological Sciences
Location: Basement, Table 12, Position 2, 1:45-3:45

Foreland basins comprise some of the most prolific hydrocarbon producing reservoirs and source rocks in the North American Rocky Mountain region. One of these major producing basins is the Powder River Basin (PRB). Located in northeastern Wyoming and extending into southeastern Montana, the PRB is one of Wyoming’s largest and most active hydrocarbon producing basins. The basin comprises various Mesozoic and Paleozoic strata with productive conventional and unconventional plays. Various studies have been done on both Mesozoic and Paleozoic stratigraphy within the basin. Historically, Cretaceous stratigraphy has been well studied and documented within the basin. However, continual industry innovations in the collection, development, and processing of subsurface geological data are making possible more refined understanding of Cretaceous stratigraphy in the basin.

This study focuses on the upper Lower Cretaceous Muddy Sandstone Formation and lower Upper Cretaceous Mowry Shale intervals at basin scale, and the implications for tectonic and eustatic evolution prior to the development of the PRB. Which controlled sedimentation, infilling, and Total Organic Carbon (TOC) weight percentage distributions of the two formations. There is a general agreement that the Mowry can be divided into upper, middle, and lower sections. The middle section has been found to contain the highest TOC percentages based on prior work done with geochemical analysis. This study will update these findings with newly collected digital well data and produce higher-density regional basin coverage with type wells, while also utilizing petrophysical calculation methods to determine TOC percentages to compare with current geochemical analysis.

The Muddy being an older conventional reservoir and the Mowry a more recent unconventional play, the collection and utilization of digitized well log data from Enverus Prism with Petrel Software, in conjunction with analysis of in-house core, provides an effective approach for producing refined structure, isochore, net sand, and TOC maps for the basin. This information can then be used in generating interpretations of sedimentation history, basin infilling, and TOC distribution. In addition, published type wells with correlated Paleozoic stratigraphy from the United States Geological Survey (USGS) are being used to generate PRB subsidence curves for multiple well locations throughout the basin to compare with maps and figures produced in Petrel. To further enhance sedimentation interpretations, U-Pb detrital zircon analysis is being conducted on the Muddy Formation sandstones collected from core. This data will be compared with published detrital zircon and subsidence work done in the western neighboring Big Horn Basin and its equivalent Muddy Formation interval.

Location: Second Floor, Table 5, Position 2, 11:30-1:30

Carbon is the elemental foundation for all living things on Earth. Soil carbon sequestration is a process in which carbon dioxide is removed from the atmosphere and stored in the soil. We want to examine the soil quality and the stability of carbon in an urban farm in North Texas by comparing measurements collected in October 2022 against measurements observed and collected in October 2023. Our research question is, “What is the effect of composting on the carbon quality and quantity at the farm?” The experimental points were chosen for comparison from a previous evaluation of a 1/3-acre section of a local urban farm next to the Trinity River in Fort Worth, Texas. We collected bulk soil samples at 0-15 cm and 15-30 cm depths from ten field points previously tested with an additional 3 new control points. Thermogravimetric Analysis (TGA) will be used to determine carbon quality by analyzing derivative weights change plots. The data collected suggests that within a year the experimental farm site has maintained a good quality of soil with minor acidification and compaction, as well as an increase in level and quality of carbon. The observed farm remains an appropriate site for providing food security, eliminating food waste while simultaneously sequestering carbon.

Advisor(s): Esayas Gebremichael Geological Sciences Arthur Busbey Geological Sciences
Location: First Floor, Table 5, Position 1, 11:30-1:30

The dermal ornamentation of reptiles and lower vertebrates is a largely untouched field of research, and thus common patterns or a specific purpose for the ornamentation has yet to be identified and/or agreed upon by paleontologists. This study strives to use various spatial and image analysis techniques to identify any patterns in the ornamentation on the skulls of both ‘lower’ vertebrate captorhinids and modern crocodilians to better understand the purpose of such ornamentation and why it has persisted from lower vertebrates to modern-day reptiles. Any information that can be derived from the research may aid modern understanding of the evolution from lower vertebrates to modern reptiles.
