ABSTRACT
Effect of Reproductive Efficiency in Regards to Workload on Peripheral Circulations of Blood Cortisol and Leptin in the Open Mare
(December, 2016)
Michaelle Kathleen Coker, B.S., Texas A&M University
Thesis Director: Dr. John Michael Mehaffey
Quarter and Paint horse mares (n= 9) were randomly assigned to 1 of 3 groups after being blocked based by expected conception date. Groups consist of mares on no work (NW), light work (LW), and moderate work (MW). Blood was taken weekly via jugular venipuncture prior to first heat cycle from each mare. Additionally, blood was taken at time of ovulation and then weekly …
The Influence Of The Invasive Chinese Tallow (Triadica Sebifera) Leaf Litter On Aquatic Chemistry And Microbial Community Composition, Raymond D. Montez
The Influence Of The Invasive Chinese Tallow (Triadica Sebifera) Leaf Litter On Aquatic Chemistry And Microbial Community Composition, Raymond D. Montez
Electronic Theses and Dissertations
Global climate change and anthropogenic activity have facilitated the movement and invasive potential of nonnative plants in native environments. These invasions can have negative effects on ecosystem diversity and function. The nonnative and invasive plant, Chinese Tallow (Triadica sebifera), has already invaded much of the south eastern US where it is outcompeting native tree species and changing ecosystem diversity in a variety of habitats. Leaf litter from the Chinese tallow has been shown cause changes in dissolved oxygen and pH in the aquatic environment. Turbidity is also affected when Chinese tallow litter is present in water. A series of …
Determining Public Perceptions Toward Wildland Fire In The Veluwe Region Of The Netherlands, Amy Brennan
Determining Public Perceptions Toward Wildland Fire In The Veluwe Region Of The Netherlands, Amy Brennan
Electronic Theses and Dissertations
The Netherlands has been facing a growing threat of wildfires due to warmer
and drier weather patterns. The purpose of this study was to identify public
perceptions toward wildland fire in the forested Veluwe region of the country. The
Dutch have little experience with wildland fires or fire as a management tool. In a
collaborative effort between Stephen F. Austin State University and the Instituut
Fysieke Veiligheid, the Dutch public safety agency, a survey was distributed to
residents and visitors to the Veluwe to reveal and quantify public opinions and
perceptions regarding wildland fire and public expectations of government
agencies …
Breeding Season Avian Community Composition And Prey Availability In Eucalyptus And Slash Pine Plantations Of Southwestern Louisiana, Elizabeth J. Messick
Breeding Season Avian Community Composition And Prey Availability In Eucalyptus And Slash Pine Plantations Of Southwestern Louisiana, Elizabeth J. Messick
Electronic Theses and Dissertations
The increased demand for wood products related to industries such as bioenergy and paper has resulted in a need for a consistent supply of raw materials. Eucalyptus (Eucalyptus spp.) plantations have the potential to boost wood production for pulpwood and biomass feedstocks. Species characteristics such as rapid, indeterminate growth, coppice regrowth, resistance to disease and insects, and tolerance of a range of environmental conditions make these species successful short-rotation woody crops (SRWCs). Camden white gum (Eucalyptus benthamii), a more cold tolerant species, has made management of eucalyptus plantations viable in southern portions of the United States such …
Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch
Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch
Electronic Theses and Dissertations
At the western edge of the longleaf pine (Pinus palustris) range, federal land managers have burned the forests of Big Thicket National Preserve to bring back the structure and diversity of the longleaf pine forest. In the early 1990’s, a four year study was conducted by Rice University, and the National Park Service continued monitoring the study’s fire ecology research plots. After two decades of data collection, ordination was applied to species abundance data to examine changes in vegetation communities from a variety of prescribed fire treatments and controls. The vegetation data was separated by size class to include overstory, …
Effects Of Acute Exercise On Postprandial Lipemia And Postprandial Glycemia, Stephen Decker
Effects Of Acute Exercise On Postprandial Lipemia And Postprandial Glycemia, Stephen Decker
Electronic Theses and Dissertations
Introduction: Moderate-intensity aerobic exercise has been shown to attenuate the rise in triglycerides in during the postprandial period, however the effects of acute bouts of high-intensity exercise on postprandial lipemia and glycemia have not been explored. The purpose of this study was to examine the effects of acute high-intensity interval training on postprandial lipemia and postprandial glycemia.
Methods: Ten healthy males participated in a randomized crossover design consisting of one high-intensity exercise session and one sedentary control session, followed by consumption of a mixed meal. Blood triglyceride and glucose concentrations were monitored following the consumption of the meal.
Results: High-intensity …
An Investigation Of Hydrogeologic, Stratigraphic, And Structural Controls On Acer Grandidentatum Communities In A Karst Landscape, Owl Mountain Province, Fort Hood Military Installation, Texas, Melinda S. Faulkner
Electronic Theses and Dissertations
The Owl Mountain Province is located within the Fort Hood Military Installation, an approximately 880 km2 installation established in the 1940s in Bell and Coryell counties, Texas, which has undergone extensive land use changes associated with military training, maintaining much of the vegetation in early succession. This study investigates thelithologic, stratigraphic, and structural controls on the hydrologic, hydrogeologic, and geomorphologic evolution of the Owl Mountain Province as expressed by mesic vegetation communities, including Pleistocene relicts Acer grandidentatum, within karst terrains. These systems exhibit complexly overprinted speleogenetic evolutions within a dynamic groundwater regime resulting from regional climate shifts throughout the …
Comparison Of Two Body Weight Screenings Of Self-Conscious Emotions And Coping, Rachel N. Nanez Ms.
Comparison Of Two Body Weight Screenings Of Self-Conscious Emotions And Coping, Rachel N. Nanez Ms.
Electronic Theses and Dissertations
Novel technologies are currently being utilized in fitness and clinical settings. However, there is not much research to examine the emotional responses to such screenings.
PURPOSE: To examine the group differences between the FIT3D and DXA protocol on emotional responses and the differences between weight classifications.
METHODS: The Body and Appearance-related Self-conscious Emotions Scale and WEIGHTCOPE were used to assess self-conscious emotions and intention to utilize 10 different weight-related coping strategies following the scans. Motivation was measured by a 10-point Likert scale measuring motivation pre and post scans.
RESULTS: There were no differences in motivation, affective response, or intention to …
Stop The Pricks: A Validation Study Of A Noninvasive Lactate Threshold Device, Rebecca M. Mcmorries
Stop The Pricks: A Validation Study Of A Noninvasive Lactate Threshold Device, Rebecca M. Mcmorries
Electronic Theses and Dissertations
ABSTRACT
Purpose: The aim of this study is to assess the validity of a noninvasive lactate threshold device (NID) to determine lactate threshold heart rate (LTHR) and aerobic threshold heart rate (AeTHR).
Methods: Twenty-one recreational athletes completed a personalized graded exercise test on a treadmill. All participants wore the noninvasive device and blood lactate samples were taken at the end of 3-minute stages. Lactate threshold heart rate and aerobic threshold heart rate were then calculated using four traditional methods and compared against the same heart rate values calculated by the device.
Results: No significant differences were found in lactate threshold …
