Facilitation plays a key role in Marsh-Mangrove interactions along a salinity gradient in South Texas
(2018-08)Climate change is resulting in fewer and less intense freezes which allows tropical mangroves, Avicennia germinans, to expand into saltmarshes in the Gulf of Mexico, causing a regime shift from herbaceous to woody plant ... -
The risk assessment capability and defense induction strategy of the Eastern Oyster Crassostrea virginica
(2018-08)Prey respond to predation risk by implementing defensive mechanisms such as avoidance behavior, interrupting the periodicity of their life history, and altering their morphology. Prey employ defensive mechanisms at a cost ... -
UAS multispectral imaging for detecting plant stress due to iron chlorosis in grain sorghum
(2018-08)This study uses a small Unmanned Aircraft System (sUAS) equipped with a multispectral sensor to assess various Vegetation Indices (VIs) for their potential to monitor iron chlorosis levels in a grain sorghum crop. Iron ... -
Applying segmentation and neural networks to detect and quantify marine debris from aerial images captured by unmanned aerial system and mobile device
(2018-08)Marine debris is a global issue with adverse impacts on the marine environment, wildlife, economy, and human health. Its presence on beaches may vary due to topography, hydrological conditions, proximity to litter sources, ... -
Effectiveness of community-managed "rest areas" in restoring a population of broadcast-spawning marine invertebrates
(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, ... -
How and when: the development and strategic maintenance of supervisor-subordinate blended relationships in the workplace
(2018-08)This study explores the development and maintenance strategies of blended supervisor subordinate relationships in the workplace, or those friendships that develop in and outside of work. The motives that drove ... -
Quantifying and characterizing the Mississippi River's contribution of microplastic debris to the Gulf of Mexico
(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 ... -
The relationship between the Army physical fitness test and a twelve-mile ruck
(2018-08)The purpose of this study was to investigate the association between the Army Physical Fitness Test (APFT) and the twelve-mile ruck assessment of Army Reserve Officer Training Corps (ROTC) cadets (CDT’s). The APFT is a ... -
Investigating the isotopic composition of reactive nitrogen in a South Texas estuary (Baffin Bay)
(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 ... -
Feminist identity and the personal epistemologies of Latina college students
(2018-08)The current study examines the relationships between women’s ways of knowing, ethnicity, and feminist identity, making use of Belenky et al’s (1986) research paradigm published in Women’s Ways of Knowing (WWK). The focus ... -
Inferring the phylogenetic relationships within two fish genera: insights into the biogeography of the northern Gulf of Mexico
(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 ... -
Social status influence on implicit bias
(2018-08)Stereotypes help us quickly make sense of the world by categorizing people into groups and making assumptions about them based off this group membership. According to Social Role Theory, stereotypes form by observing gender ... -
Characterizing marine subsurface fungi from oligotrophic South Pacific Gyre sediments
(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
(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
(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 ... -
Social anxiety interventions: reappraisal versus acceptance and values
(2018-08)Social anxiety is a prevalent psychological difficulty, and even individuals who do not meet criteria for the diagnosis can demonstrate functional impairment. Cognitive Behavioral Therapy (CBT) has been the most established ... -
Do phycosphere-associated bacteria affect the growth and lipid production of phaeodactylum tricornutum bohlin?
(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.
(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
(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)
(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 ...
