Biodiversity, ecology, and natural history of polychaetous annelids from the Gulf of Mexico
(2013-11-15) Reuscher, Michael Gerhard; Shirley, Thomas C.; Tunnell Jr., John W.; Pezold, Frank L.; Schulze, Anja; Withers, Kim; Cifuentes, Lauren; Canales, JoAnn
Polychaetes are abundant and ecologically important benthic organisms, yet their diversity and phylogenetic relationships are far from being resolved. The purpose of my dissertation was to measure their diversity in the Gulf of Mexico and to compare polychaete assemblages of different regions, depths, and sampling periods. Furthermore, I studied the natural history of the diverse polychaete family Paraonidae. The polychaete diversity of the Gulf of Mexico was examined using a comprehensive species database. Species were assigned to ecological, morphological, and biogeographical categories and each category's contribution was examined throughout different depths and regions. Spatial and temporal comparisons of polychaete assemblages were conducted at three transects on the northern Gulf of Mexico continental slope. Phylogenetic relationships within the family Paraonidae were studied based on the examination of type material. Polychaete diversity changed with depth. The shelf break was accompanied by a steep change in the species composition. The southeastern Gulf had the most distinct polychaete fauna. Endemism was at 10%; in the deep-sea more than 30% of the species were endemic and the relative contribution of carnivorous species doubled. At the continental slope, abundance did not continuously decrease with depth between 350 and 1500 m, but dropped between 1500 and 2100 m. Abundance in the spring was approximately twice as high as in the fall, in depths up to 1500 m. Polychaete assemblages changed continuously with increasing depth. Short-term temporal changes of polychaete assemblages had reversed in the long run. In the cladistic analyses, monophyly of Paraonidae was supported. Its synapomorphies are the complete fusion of prostomium and peristomium and the dorsal location of the anus. Cirrophorus and Paradoneis should be considered synonyms. The prostomial antenna, which was used to distinguish both genera, is a homoplastic character. Two species of Paradoneis are being moved to a new genus. Spatial and temporal patterns of polychaete diversity in the Gulf of Mexico were discovered. Additional sampling efforts are needed for a more complete picture of the diverse polychaete fauna. The phylogenetic analyses based on morphology resolved important issues. However, additional genetic markers are needed to uncover sister species relationships.
Open Access Publication Fund Annual Report: 2023 - 2024
(2024-06) Hight, Alexa
The Open Access Publication Fund at Texas A&M University-Corpus Christi underwrites author publication charges for open access scholarly journal articles, book chapters, and monographs. The fund seeks to encourage greater participation in open access publishing so that Texas A&M University-Corpus Christi’s research is free of subscription barriers, and we support the adoption of open science practices that can help sustain Texas A&M University-Corpus Christi’s status as an R2 Doctoral University. Numerous research studies show that OA publishing increases the visibility of publications, thereby increasing visibility, citations, and the use of faculty research all of which enhance the reputation of TAMU-CC and its faculty.
Major outcomes for 2023 - 2024:
• The Open Access Publication Fund distributed funds for 51 faculty, staff, and graduate students from all 6 colleges as well as the Harte Research Institute for the Gulf of Mexico Studies, the Conrad Blucher Institute, and the Center for Water Supply Studies.
• The Open Access Publication Fund supported the publication fees for 25 articles and one book chapter for a total amount of funding distributed of $52,624.69.
Terrestrial lidar data classification based on raw waveform samples versus online waveform attributes
(IEEE, 2021-12-03) Pashaei, Mohammad; Starek, Michael J.; Glennie, Craig L.; Berryhill, Jacob
In this study, the potential of raw samples of digitized echo waveforms collected by full-waveform (FW) terrestrial laser scanning (TLS) for point cloud classification is investigated. Two different TLS systems are employed, both equipped with a waveform digitizer for access to the raw waveform and online waveform processing which assigns calibrated waveform attributes to each point measurement. Point cloud classification based on samples of the raw single-peak echo waveform is compared with point cloud classification based on the calibrated online waveform attributes. A deep convolutional neural network (DCNN) is designed for the supervised classification. Random forest classifier is used as a benchmark to evaluate the performance of the proposed DCNN model. In addition, feature importance and temporal stability of the raw waveform samples versus the calibrated waveform attributes for point cloud classification are reported. Classification results are evaluated at two study sites, a built environment on a university campus and a coastal wetland environment. Results show that direct classification of the raw waveform samples outperforms classification based on the set of waveform attributes at both study sites. Results also show that the contribution of the range, as the only geometric attribute in the raw waveform feature vector, significantly increases the classification performance. Finally, the performance of the DCNN for filtering ground points to generate a digital terrain model (DTM) based on classification of the raw waveform samples is assessed and compared to a DTM generated from a progressive morphological filter and to real-time kinematic (RTK) GNSS survey data.

Conference Proceedings: 2024 Symposium for Student Innovation, Research, and Creative Activities
(Texas A&M University-Corpus Christi, 2024-04-26)
The 2024 Symposium for Student Innovation, Research, and Creative Activities (SSIRCA) is sponsored by the Division of Research and Innovation, in collaboration with the College of Business, the College of Education and Human Development, the College of Engineering and Computer Science, the College of Liberal Arts, the College of Nursing and Health Sciences, the College of Science, the School of Arts, Media and Communication, and the Mary and Jeff Bell Library. SSIRCA is also supported by the Honors Program, the McNair Scholars Program, and Louis Stokes Alliance for Minority Participation Program. Students from all colleges at TAMU-CC were invited to give presentations, and their faculty members were encouraged to participate by helping to review presentation proposals and evaluate presentations. The keynote speaker was Dr. Valerie Young.
