• Effectiveness of community-managed "rest areas" in restoring a population of broadcast-spawning marine invertebrates 

  Bennett, Brenda Sue (2018-08)

  Due primarily to overharvesting, marine fisheries have been declining for decades and achieving sustainable fisheries has proved challenging. Top-down, enforcement-centric fisheries management has been largely ineffective, ...

• Quantifying and characterizing the Mississippi River's contribution of microplastic debris to the Gulf of Mexico 

  Martin, Katherine Marie (2018-08)

  Plastics presence in the ocean is becoming increasingly ubiquitous which is widely recognized by the public, scientific communities, and government agencies. However, only in the past decade have plastics, specifically ...

• Investigating the isotopic composition of reactive nitrogen in a South Texas estuary (Baffin Bay) 

  Campbell, Jacquelyn (2018-08)

  Harmful algal blooms (HABs) have the potential to adversely affect the water quality of estuaries and, consequently, their ability to support healthy and diverse ecosystems. Since 1989, Baffin Bay, a semi-arid south Texas ...

• Inferring the phylogenetic relationships within two fish genera: insights into the biogeography of the northern Gulf of Mexico 

  Hunt, Elizabeth P. (2018-08)

  A suture zone can be defined as a geographic area where faunal assemblages meet and in which pairs of taxa (species, semi-species, etc.) have come back into secondary contact and may hybridize. While identifying these areas ...

• Characterizing marine subsurface fungi from oligotrophic South Pacific Gyre sediments 

  Sobol, Morgan Starr (2018-08)

  Fungal communities from the deep marine subsurface may be important in global biogeochemical cycles through remineralization of sedimentary organic matter, but this has not yet been thoroughly observed. This study analyzes ...

• Effects of extreme freshwater events and perkinsus marinus on crassostrea virginica stress response 

  Zimmermann, Danielle (2018-08)

  Estuarine salinity is one of the most important factors affecting oyster (Crassostrea virginica) growth and Perkinsus marinus disease characteristics. The combined effect of increased freshwater inflows and P. marinus ...

• Bringing a state government agency into the 21st century through geographic information systems (gis) streamlining workflow by integrating database management systems and gis for a non-riparian water use permitting program 

  Jackson, Shawn Lynnette (2018-08)

  Government entities, both Federal and State, are two of the largest collectors, repositories, and disseminators of digital data. Management of the data is an asset if the system is well designed and developed. This thesis ...

• Do phycosphere-associated bacteria affect the growth and lipid production of phaeodactylum tricornutum bohlin? 

  Chorazyczewski, Adam M. (2018-08)

  Microalgae biofuels are a promising alternative to fossil fuel energy. However current microalgal biofuel production is inefficient making it more expensive than fossil fuels. To make microalgal biofuels a realistic ...

• Multiple stressor effects on macrobenthic communities in Corpus Christi Bay, Texas, U.S.A. 

  Smith, Jamie Kathryn (2018-05)

  At any moment in nature, organisms are likely being exposed to multiple stressors, the effects of which are difficult to separate. Often, however, environmental stressors are considered on an individual basis. In southeastern ...

• Detection of plant characteristics and a comparison of effectiveness between 2d and 3d data visualization in supporting human perception of plant characteristics 

  Pham, Thanh Van (2018-05)

  Efficient agriculture requires the assessment of plant characteristics. A higher crop yield can be achieved with good quality plant characteristic data. In this research, a system was developed using the algorithms presented ...

• The importance of low salinity habitat to Red Drum (Sciaenops Ocellatus) 

  Torrance, Louisa E. (2018-05)

  Red drum (Sciaenops ocellatus) is an estuarine-dependent species capable of survival in fresh and low salinity habitats. Standardized sampling by Texas Parks and Wildlife Department (TPWD) for various life stages of red ...

• A comparison of tracheal morphology and elastin abundance in bottlenose dolphin (cetacea: tursiops truncatus) and white-tailed deer (artiodactyla: odocoileus virginianus) 

  Scerbo, Andrew A. (2018-05)

  Odontocete species exhibit diving strategies to exploit various resources in marine waters. While the phenomenon of lung collapse has been studied, the morphology and fine structure of the respiratory conducting regions ...

• Oil spill detection is SAR images using meta-heuristic search algorithms 

  Manikonda, Sai Vinay Teja (2018-05)

  In recent years, oil spill accidents have become increasingly frequent due to the development of marine transportation and massive oil exploitation. At present, satellite remote sensing is the principal method used to ...

• Non-commutative weak*-continuous operator extensions 

  Flores, Luis Carlos (2018-05)

  Extension theorems such as the Hahn-Banach Extension Theorem are a central idea of functional analysis. In 1962, Gleason and Whitney proved an extension theorem for weak*-continuous, linear functionals on H^∞ (D) to positive, ...
