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.

Vulnerability of Wetlands due to Projected Sea-Level Rise in the Coastal Plains of the South and Southeast United States
(Remote Sensing for Wetland Restoration, 2024-06-07) Lizcano-Sandoval, Luis; Gibeaut, James; McCarthy, Matthew; Murray, Tylar; Rueda-Roa, Digna; Muller-Karger, Frank
Coastal wetlands are vulnerable to accelerated sea-level rise, yet knowledge about their extent and distribution is often limited. We developed a land cover classification of wetlands in the coastal plains of the southern United States along the Gulf of Mexico (Texas, Louisiana, Mississippi, Alabama, and Florida) using 6161 very-high (2 m per pixel) resolution WorldView-2 and WorldView-3 satellite images from 2012 to 2015. Area extent estimations were obtained for the following vegetated classes: marsh, scrub, grass, forested upland, and forested wetland, located in elevation brackets between 0 and 10 m above sea level at 0.1 m intervals. Sea-level trends were estimated for each coastal state using tide gauge data collected over the period 1983–2021 and projected for 2100 using the trend estimated over that period. These trends were considered conservative, as sea level rise in the region accelerated between 2010 and 2021. Estimated losses in vegetation area due to sea level rise by 2100 are projected to be at least 12,587 km2, of which 3224 km2 would be coastal wetlands. Louisiana is expected to suffer the largest losses in vegetation (80%) and coastal wetlands (75%) by 2100. Such high-resolution coastal mapping products help to guide adaptation plans in the region, including planning for wetland conservation and coastal development.

Scientific Principles for Definition of Environmental Flows
(2005-10-31) Maidment, David; Montagna, Paul; Sansom, Andrew; Ward, George; Winemiller, Kirk
This memorandum describes some scientific principles for the establishment of environmental flow requirements in Texas streams, rivers, bays and estuaries. There are four general principles: 1) The soundness of ecological integrity is ensured by sustainability of natural resources. 2) Field measurements are the keystone to assessing and understanding ecosystem components and processes. 3) Scientific inference should be used to establish the relationship between the ecological integrity of an aquatic ecosystem and its associated environmental flows. 4) Adaptation of assessment procedures. These four principles can guide the scientific development of environmental flow requirements in Texas surface waters.

Reef design influences habitat provision on a restored oyster reef
(Frontiers in Marine Science, 2024-05-30) Pollack, Jennifer Beseres; Sugla, Monisha; Breaux, Natasha; Trackenberg, Stacy; Palmer, Terence
Habitat restoration efforts are often limited by cost, making it important that available funds are used efficiently and effectively to achieve desired restoration goals. In this study, we evaluate habitat provision for oysters and motile epifauna on restored oyster reefs in a northwestern Gulf of Mexico estuary constructed with discrete high vertical relief (~0.6m“reef mounds”) or continuous low vertical relief (<0.08 m “reef flats”). Habitat provision on reef mounds exceeded that on reef flats within one month of construction and supported 0.75x higher oyster density, 2x higher motile epifauna biomass, and 3.6x higher motile epifauna density one year after construction. Oyster density on reef mounds remained relatively high throughout the study period, with ~2x higher oyster densities than reef flats 18 months after construction and ~1.5x higher oyster densities by the end of the study. Both reef mounds and reef flats increased oyster and epifaunal densities compared to unrestored areas. Although on-reef oyster densities were higher on reef mounds than reef flats, the total restored oyster areal density and volumetric density was higher in restored reef flat areas, primarily because the restored flats area had no gaps within its restoration boundaries. Our findings have practical value for better predicting restoration outcomes and achieving desired restoration goals based on restored oyster reef height, with reef mounds maximizing on-reef oyster and epifaunal densities and reef flats maximizing the total number of oysters per area restored or volume of substrate purchased. Understanding the benefits and tradeoffs between restoration designs will allow resource managers to improve cost-efficiencies in future restoration projects.
