Effects Of Site Preparation, Seed Germination, And Harvest Maturity On Wiregrass Restoration Efforts At Fort Stewart, Ga, Nickey Garrett Anderson Apr 2013

Effects Of Site Preparation, Seed Germination, And Harvest Maturity On Wiregrass Restoration Efforts At Fort Stewart, Ga, Nickey Garrett Anderson

Electronic Theses and Dissertations

Wiregrass (Aristida stricta Michx.) was once the dominant ground cover species within the Atlantic Coastal Plain longleaf pine (Pinus palustris Mill.) ecosystem. Less than 1 million hectares of intact longleaf pine-wiregrass communities remain, due primarily to anthropogenic activities. Wiregrass is a keystone species in the longleaf pine ecosystem, as its presence facilitates the natural fire regime, a critical component in the perpetuation of these communities. Therefore, there is increased interest in wiregrass restoration in both existing longleaf pine communities and future longleaf pine restoration sites. Many restoration sites are on tracts that have been cleared of all vegetation. Removal of ...


Assortative Mating In Ixodes Scapularis (Acari: Ixodidae) Ticks? And Ixodes Scapularis Infest Male Deer More Often Than Female Deer At Savannah River Site, (Aiken, Sc), Jenny Dickson Apr 2013

Assortative Mating In Ixodes Scapularis (Acari: Ixodidae) Ticks? And Ixodes Scapularis Infest Male Deer More Often Than Female Deer At Savannah River Site, (Aiken, Sc), Jenny Dickson

Electronic Theses and Dissertations

In this study we explored the hypothesis that the mitochondrial genetic diversity observed in Ixodes Scapularis ticks in the Southeastern United States is maintained through assortative mating. The study of 319 couples of ticks collected in copula from deer at the Savannah River Site (Aiken, SC) showed that ticks assigned to mitochondrial (12SrDNA and d-loop genes) phylogenetic monophyletic clades do not chose their mating partner based on genetic similarity or genetic diversity. The genetic composition of couples did not differ significantly from random choice. Our data indicate that if genetic diversity is maintained in this tick population, this cannot be ...


Attraction To Physical Activity Of Generation Z - A Mixed Methodological Approach, David Biber Apr 2013

Attraction To Physical Activity Of Generation Z - A Mixed Methodological Approach, David Biber

Electronic Theses and Dissertations

The prevalence of obesity in Generation Z, which includes individuals born after the year 2000, has tripled that of Generation Xers of 1980 (Ogden et al., 2010). Rising levels of obesity have been associated with increased physical inactivity (WHO, 2013). Attraction to physical activity can be grounded in the Self-Determination Theory (SDT; Deci & Ryan, 1985), which defines intrinsic and extrinsic motivation and the roles each type of motivation plays in social and cognitive development. The purpose of the current research was to use a mixed-methodological approach to understand attraction to physical activity of a Generation Z sample via semi-structured focus ...


The Role Of Social Physique Anxiety, Social Support, And Perceived Benefits And Barrier To Exercise In All-Female Fitness Camp Intervention, Lauren Elizabeth Easton Apr 2013

The Role Of Social Physique Anxiety, Social Support, And Perceived Benefits And Barrier To Exercise In All-Female Fitness Camp Intervention, Lauren Elizabeth Easton

Electronic Theses and Dissertations

Only 3.2% of Americans ages 20-59 years meet the minimum recommended volume of exercise suggestions. In addition to the substantial percentage of people who fail to meet exercise requirements, only 15% of American adults engage in exercise on a regular basis, i.e. exercising for twenty minutes at least three times per week to improve health. (Schrop, Pendleton, McCord, Gil, Stockton, McNatt, & Gilchrist, 2006). Although the small proportion of those who reach the suggested physical activity levels is a topic of concern for adults, the CDC reports that physical inactivity levels are even higher for females than those of ...


The Influence Of The Initiation Of A Graded Exercise Protocol On Dynamic Postural Stability Following A Concussion, Lauryn Hunter Apr 2013

The Influence Of The Initiation Of A Graded Exercise Protocol On Dynamic Postural Stability Following A Concussion, Lauryn Hunter

Electronic Theses and Dissertations

Current post-concussion assessment tools may lack sensitivity in identifying recovery. Athletes demonstrating decreased postural control may have an increased likelihood of suffering sports-related injury. Exercise has been shown to briefly alter static postural control and the visual contribution to static postural stability deteriorates with moderate intensity exercise. Gait variability, defined as the fluctuation in gait characteristic between steps, is a sensitive measure of postural stability in populations with higher level gait disorders. Objective: The purpose of this study was to examine the influence of a progressive exertional return-to-play program on dynamic postural stability following a concussion. Design: Prospective longitudinal. Setting ...


Perceptions Of Deliquency Among Male Athletes And Non-Athletes: A Qualitative Investigation, Humphrey Nartey Apr 2013

Perceptions Of Deliquency Among Male Athletes And Non-Athletes: A Qualitative Investigation, Humphrey Nartey

Electronic Theses and Dissertations

It is presumed that the involvement in sports helps to deter delinquency, yet athletes who seemingly have it all engage in destructive delinquent lifestyles (Savini, 2008). Many theorists contend that the "jock identity" or "sport hubris" is largely responsible, as people think they will be treated more favorably if they are athletes (Miller et al., 2006). This perception raises the question of whether athletes know and understand the constructs of delinquency. Thus the purpose of this study was to examine male athletes' and non-athletes' perceptions of the minor and major substrates of delinquency. A semi-structured interview was used to gather ...

Variation In Egg Components: A Study Of Maternal Investment And Resource Partitioning In The Nesting Loggerhead Sea Turtle; Estimating Genic Variation And Mapping Genetic Lineage Of A Rare Captive Helodermatid Population: Heloderma Horridum Charlesbogerti, Ketan V. Patel

Electronic Theses and Dissertations

Loggerhead sea turtles have the highest egg yields of any oviparous non-avian reptiles. Blood urea nitrogen levels increased as the season progressed while total blood albumen and total protein levels decreased. Wet egg mass (H = 1.7719 df = 2 p = 0.0375*) and albumen mass (H = 6.0507 df = 2 p = 0.0485*) significantly decreased across the nesting season however, wet yolk did not. Analysis of dried egg components showed that dry yolk and albumen did not differ across the nesting season. In addition on no seasonal change in dried egg components, hatchling size was conserved across the nesting season ...


Ncaa Division I Head Coaches' Experiences With Eating Disorders And Disordered Eating In Female Athletes: A Qualitative Analysis, Caitlyn Pecinovsky Apr 2013

Ncaa Division I Head Coaches' Experiences With Eating Disorders And Disordered Eating In Female Athletes: A Qualitative Analysis, Caitlyn Pecinovsky

Electronic Theses and Dissertations

In today's sport, NCAA Division I female athletes are under a constant pressure to reach an elite level of perfection in athletic performance, frequently adhering to the assumption that there is an inverse relationship between body size and performance level (Petrie & Sherman, 2007). Additionally, coaches have unrealistic expectations about weight and body image, which adds pressure on athletes to conform to certain weight or image driven standards. Perceptions that coaches hold about eating disorders and disordered eating present a set of risk factors that may increase the likelihood of female athletes developing maladaptive eating patterns (Scoffier, Maiano, & d'Arripe-Longueville ...


Enjoyment Based Motivation And The Enjoyable Exercise Experience In A Generation Y Sample: A Mixed Methods Approach, Jonathan Stewart Apr 2013

Enjoyment Based Motivation And The Enjoyable Exercise Experience In A Generation Y Sample: A Mixed Methods Approach, Jonathan Stewart

Electronic Theses and Dissertations

Individuals who choose to live a healthy lifestyle often have different preferences for a variety of exercise activities, exercise settings and eating plans. In fact, numerous researchers have examined the preferences of individuals in diet and exercise programs from past generations (Daley, Copeland, Wright, & Wales, 2008; Ekkekakis, Hall, & Petruzzello, 2005). Numerous research studies have examined the correlation between exercise adherence and exercise enjoyment (Bartlett, Close, Maclaren, Gregson, Drust, & Morton, 2011; Ebben & Brudzynski, 2008; Fleig, Lippke, Pomp, & Schwarzer, 2011; Frederick-Recascino, 2002; Leslie, Owen, Salmon, Bauman, Sallis, & Lo, 1999). However, little research has been found investigating the optimal exercise experience of the current college aged generation. The first purpose was to compare obese and nonobese members as well as sufficiently and insufficiently active members of Generation Y on Enjoyment Based ...

Objective: To identify acute alterations of scapular upward rotation following a functional fatigue protocol. Design: Prospective longitudinal. Setting: Biomechanics research laboratory. Patients or Other Participants: Twenty healthy, male competitive tennis players with no history of shoulder injury participated in this study: 10 experimental subjects(19.4 ± 1.07 yrs., 180.09 + 8.92 cm 72 + 11.56 kg) and 10 control subjects (19.6 ± 1.17 yrs., 181.1 + 6.56 ...


In Vitro Cultivation Of The Microphallid Trematode Gynaecotyla Adunca, Jenna West Apr 2013

In Vitro Cultivation Of The Microphallid Trematode Gynaecotyla Adunca, Jenna West

Electronic Theses and Dissertations

It is important to study the cultivation of parasites in vitro for many reasons, such as to aid in developing antihelminthic drugs and vaccines, to eliminate the need for vertebrate hosts in parasite culture, and to more easily study the genetics and the biology of parasites. Trematodes have complex life cycles with multiple hosts which makes them difficult to grow in vitro. However, microphallid trematodes are excellent candidates for parasite in vitro cultivation because they are short lived and progenetic. The goal of my study was to optimize in vitro culture conditions for the microphallid trematode, Gynaecotyla adunca. I determined ...

Concussion Knowledge In Amateur Motocross, Kristina Miller Jan 2013

Concussion Knowledge In Amateur Motocross, Kristina Miller

Electronic Theses and Dissertations

The Center for Disease Control and Prevention estimated that there are 1.6-3.8 million sports related traumatic brain injuries in the United States annually which occur in both mainstream and extreme sports. Many of these concussions have been associated with collisional sports, like football, but high risk extreme sports, like motocross, also have many opportunities for collisions to occur. Unlike traditional varsity sports motocross races, especially at the amateur level, do not require more than advanced life support at a race in case of emergency situation leaving the amateur rider to recognize and decide on concussion management. Purpose of ...


Variation In Population Densities Of The Florida Scrub Lizard (Sceloporus Woodi) Between Managed Sand Pine Scrub And Longleaf Pine Stands In The Ocala National Forest, Matthew D. Kaunert Jan 2013

Variation In Population Densities Of The Florida Scrub Lizard (Sceloporus Woodi) Between Managed Sand Pine Scrub And Longleaf Pine Stands In The Ocala National Forest, Matthew D. Kaunert

Electronic Theses and Dissertations

Population-level response to habitat fragmentation is central to applied species management and conservation. Managed landscapes are often subject to increased fragmentation and, consequently, may force once connected populations to function as metapopulations. Studies investigating metapopulations occurring over patchy, managed landscapes are of increasing importance as fragmentation is a known cause of biodiversity loss. In June-September 2012, populations of the rare, endemic Florida scrub lizard (Sceloporus woodi) were sampled across the Ocala National Forest (ONF) to compare abundance and density across two management types. In the ONF, sand-pine scrub is clearcut and rollerchopped whereas longleaf pine is managed via prescribed burning ...


Choice Response Time Differences Between Recently Recovered Concussed And Healthy Student-Athletes, Tiffen Tapia-Lovler Jan 2013

Choice Response Time Differences Between Recently Recovered Concussed And Healthy Student-Athletes, Tiffen Tapia-Lovler

Electronic Theses and Dissertations

Some 1.6 to 3.8 million sports-related concussions occur annually in the United States. Utilization of test batteries and exercise protocols are recommended to ensure athletes recover completely. Many batteries involve response time (RT) tests, which show response time increases post concussion. A major limitation of RT tests is that all are done in static position. Additionally, many studies show a lingering effect on RT. The addition of RT tests to check for lingering symptoms could be beneficial. The purpose of this study was to see if significant differences could be found in RT tests involving dynamic movement between ...


The Tick Genus Amblyomma In Africa: Phylogeny And Mutilocus Dna Barcoding, Omobolanle Kushimo Jan 2013

The Tick Genus Amblyomma In Africa: Phylogeny And Mutilocus Dna Barcoding, Omobolanle Kushimo

Electronic Theses and Dissertations

The tick genus Amblyomma includes approximately 130 species, 28 of which are found on the African continent and/ or in Madagascar. In order to understand the evolutionary phylogeography of the genus, it is necessary to gain a better understanding of the relationships between African taxa. Therefore, the main goals of this work were to, (1) reconstruct the phylogenetic relationships of the African Amblyomma available to us and (2) test markers for their usefulness as barcoding tools to link unknown immature specimens to their corresponding adults. The mitochondrial gene markers used in this study (12SrDNA and COI) did not resolve the ...


Motives For Physical Activity And Physiological Variables As Predictors Of Exercise Intentions Following A High Intensity Interval Training Protocol In College-Age Females, Sarah Joseph Jan 2013

Motives For Physical Activity And Physiological Variables As Predictors Of Exercise Intentions Following A High Intensity Interval Training Protocol In College-Age Females, Sarah Joseph

Electronic Theses and Dissertations

Recent data collected on college-aged females indicates that more females are classified as insufficiently active and may have little time for physical activity (Ligouri, et al., 2011). High intensity interval training (defined as very short intense intervals, usually above 85% maximum heart rate accompanied by alternated passive recovery periods; HIIT) has become a popular alternative to the more traditional continuous training utilized by individuals due to its time efficiency. In fact, HIIT has been shown to induce many of the same physiological changes as moderate intensity training with less training time. It is possible that college-aged females may benefit from ...
