This research project focuses on using a multiproxy approach to discriminate between overwash and non-hurricane marsh sediments within the bed of a coastal lake. 3 marsh cores were collected in an area of McFaddin National Wildlife Refuge just south of Clam Lake that are known to contain 4 hurricane overwash deposits, Ike, Rita, Carla, and Audrey. LOI and XRF analysis were used to determine the signature of the hurricane overwash layers. 3 more cores were collected from Clam Lake where there are no visible sand layers. The elemental signature of the overwash layers found in the marsh cores was used to run a hierarchical cluster analysis on the lake cores. This was able to determine the effectiveness of XRF's ability to distinguish between hurricane overwash and marsh sediments. The combination of cluster analysis, LOI, and XRF can tentatively identify hurricane overwash deposits in a coastal lake, however, it is more successful in the marsh cores. Results in the lake cores are somewhat inconsistent and uncertain, possibly because there may have not been enough overwash deposits to identity or that the XRF analysis needs more distinct sand layers to distinguish between overwash and marsh.

Photograph of eleven individuals wearing face masks (except for UNT President Neal Smatresk) and standing in front of the doorway of Eagle Landing, a newly opened UNT Dining Hall. One man with scissors is cutting into a large green ribbon flanked by green, white, and silver balloons. A group of people sitting in rows of black chairs are facing the ribbon-cutting. One person lifts a smartphone to take a picture. Also visible in the photograph is a podium with the UNT name and logo.

The Dallas-Fort Worth International (DFW) Airport is located in a densely urbanized area with one of the fastest-growing populations in the U.S.A. The airport property includes a large tract of "protected" riparian forest that is unique to the urban surroundings. This dissertation explores variables that influence the benthic macroinvertebrate community structure found in urbanized prairie streams that were initially assessed by the University of North Texas (UNT) Benthic Ecology Lab during four, non-consecutive biomonitoring studies (2004, 2005, 2008, and 2014) funded by the DFW Airport. Additionally, land use analysis was performed using 5-meter resolution satellite imagery and eCognition to characterize the imperviousness of the study area watersheds at multiple scales. Overall, flow conditions and imperviousness at the watershed scale explained the most variability in the benthic stream community. Chironomidae taxa made up 20-50% of stream communities and outperformed all other taxa groups in discriminating between sites of similar flows and urban impairments. This finding highlights the need for genus level identifications of the chironomid family, especially as the dominant taxa in urban prairie streams. Over the course of these biomonitoring survey events, normal flow conditions and flows associated with supra-seasonal drought were experienced. Prevailing drought conditions of 2014 did not …

Photograph of a sign hanging in a window by an entryway of the Edith O'Donnell Arts and Technology (ATEC) building at the University of Texas at Dallas (UTD). The sign is blue with divided colored sections in order from top to bottom: red, orange, yellow, green. The red section reads "high risk of transmission," the orange section reads "extreme caution," the yellow section reads "proceed carefully," and the green section reads "new normal until you're vaccinated." The top of the sign contains white text in capital letters that reads "Today's COVID-19 risk level" and the bottom of the sign contains white text in lowercase letters that reads "dallascounty.org/covid-19/" as well as a small black and white logo.

Photograph of a stand up sign with a large poster attached that is turquoise colored and features dark green text in capital letters, an orange header with white text in capital letters, and a dark green footer with white and orange text in capital letters and the University of Texas at Dallas logo. The large poster shows a faceless cartoon person with dark hair and a white face mask. The large poster reads, "For your health, we encourage everyone to wear a mask indoors." Behind the large poster, the image reveals a white building interior with a staircase and large windows in the distance. To the right of the sign in the image, there is a smaller A4 size paper sign posted to the wall with the image of a cartoon hand and a hand sanitizer disposal underneath the sign. The small paper sign reads "Please use hand sanitizer before entry."
