Current Recommendations For Lower Body Aerobic Exercise In Chronic Unilateral Stroke - A Systematic Review, Jordan N. Brown
Current Recommendations For Lower Body Aerobic Exercise In Chronic Unilateral Stroke - A Systematic Review, Jordan N. Brown
Electronic Theses and Dissertations
Background: Chronic stroke patients (i.e., > six months since the onset of stroke) continue to experience persistent gait complications. Once formal physical therapy concludes, exercise professionals can implement exercise interventions designed to improve quality of life and reduce risk of secondary stroke. This systematic review aimed to evaluate whether lower-body aerobic exercise transferred to gait improvements in chronic unilateral stroke. Methods: An electronic search of the following databases were undertaken: MEDLINE, CINHAL, Ovid, and SPORTdiscus. Two independent reviewers selected articles using predetermined inclusion criteria: adults (i.e., >18 years old) who suffered from a chronic unilateral stroke. Additionally, all included studies were …
Assessing Habitat Suitability Of Ribbed Mussels (Geukensia Demissa) In Georgia Salt Marshes By Examining Predicted Mussel Densities And Mussel Population Parameters, William K. Annis Jr
Assessing Habitat Suitability Of Ribbed Mussels (Geukensia Demissa) In Georgia Salt Marshes By Examining Predicted Mussel Densities And Mussel Population Parameters, William K. Annis Jr
Electronic Theses and Dissertations
Geukensia demissa (ribbed mussel) is an ecology important bivalve that has the potential to contribute to salt marsh restoration. Understanding the factors that contribute to the distribution of mussels can help inform managers on choosing locations to optimize the survivorship of mussels in restoration projects. This study sought to model mussel densities across the coast of Georgia and to compare predicted mussel densities with mussel population parameters as means to gauge habitat suitability. Mussel densities were collected through field surveys across a range of salt marshes along the coast of Georgia and were compared with spatial data such as distance …
Disease Prevalence And The Population Genetic Structure Of Crassostrea Virginica Along The Georgia Coast, Sarah Batchelor
Disease Prevalence And The Population Genetic Structure Of Crassostrea Virginica Along The Georgia Coast, Sarah Batchelor
Electronic Theses and Dissertations
The Eastern Oyster, Crassostrea virginica, is an ecologically important species that plays a role in protecting shorelines, water filtration, and providing habitat and food for various fish species. Perkinsus marinus and Haplosporidium nesloni are two pathogens currently affecting oyster populations. These pathogens have both been documented as causes of mass mortality events along the East coast. They greatly diminish the health of oysters, resulting in the degradation of oyster tissue, reduction in growth and reproductive ability, and may cause death. In this study, wild oysters were collected from eleven locations along the Georgia coast to investigate the presence, intensity, …
Using Zebrafish (Danio Rerio) To Evaluate The Use Of Food Waste Based Feed In Sustainable Small-Scale Aquaculture, Caitlin May
Using Zebrafish (Danio Rerio) To Evaluate The Use Of Food Waste Based Feed In Sustainable Small-Scale Aquaculture, Caitlin May
Electronic Theses and Dissertations
Food waste is rich in nutrients and a valuable resource, but currently its primary method of disposal in the United States (US) is unsustainable. In 2018 the US Environmental Protection Agency (EPA) estimated that the commercial, institutional, and residential sectors of the US economy wasted 63 million metric tons of food, most of which was sent to landfills. Instead, food waste could be recycled and used to supplement or replace commercial feed in aquaculture to sustainably stimulate production of fish. Zebrafish (Danio rerio) are a well characterized animal model closely related to other fish species that are important …
The Role Of Symbiotic Algae In The Acclimatization Of Oculina Arbuscula To Ocean Acidification, Erin M. Arneson
The Role Of Symbiotic Algae In The Acclimatization Of Oculina Arbuscula To Ocean Acidification, Erin M. Arneson
Electronic Theses and Dissertations
Ocean acidification (OA) caused by CO2 emissions is projected to decrease seawater pH to 7.6 by 2100. Scleractinian corals are at risk because excess H+ in seawater binds to carbonate (CO32-), reducing its availability for CaCO3 skeletons. The energy demand for skeletal growth increases as pH decreases because corals must actively purge excess H+ from their seawater sourced calcifying fluid to maintain high calcification rates. In scleractinian corals it is hypothesized that photosynthesis by symbiotic algae is critical to meet this increased energy demand. To test this hypothesis, I conducted laboratory and field …
Psychometric Evaluation Of Memory And Concentration Sections In The Standardized Assessment Of Concussion, Seungho Ryu
Psychometric Evaluation Of Memory And Concentration Sections In The Standardized Assessment Of Concussion, Seungho Ryu
Electronic Theses and Dissertations
The purpose of this study is to evaluate validate the memory and concentration sections of the Standardized Assessment of Concussion (SAC) from the SCAT5. Two studies were conducted. The first study examined item difficulty and discrimination using 10 new word lists of 3 versions in the immediate memory section using item analysis based on classical test theory and to equate scores earned on different versions of 10 word lists using test equating methods. The second evaluated the validity of digits backwards in the concentration section, and evaluated current and new scoring methods for the digit backwards. Two hundred young adults …
Creating A Georgia Southern Spider Collection: Can Dna Barcoding Help?, Guy B. Hobbs
Creating A Georgia Southern Spider Collection: Can Dna Barcoding Help?, Guy B. Hobbs
Electronic Theses and Dissertations
With over 280 spider (Araneae) species recorded within the State of Georgia, USA, the need for a well-documented natural history collection with a usable voucher system is critical to continually assess spider diversity and their future ecological impact in this region. Spider identification can be daunting for the inexperienced taxonomist; it is time consuming and sometimes requires destructive procedures. Previous works have successfully used an alternative method, DNA barcoding, to correctly identify spider species while preserving their morphology. This study set forth to create the core of a well-documented spider collection within Georgia Southern University’s Institute for Coastal Plain Science …
Lipid Metabolites As Energy Stores In Four Stingray Species, Lauren Moniz
Lipid Metabolites As Energy Stores In Four Stingray Species, Lauren Moniz
Electronic Theses and Dissertations
Assessing macronutrient transfer is important for estimating ecosystem health and structure. This nutrient transfer is facilitated through trophic position interactions and the consumption of biomass. Lipids are macronutrients that can be used to assess energy flow. Triglyceride (TAG) and free fatty acids (FFA) are important lipids that are obtained from diet and integrate into tissues. They are representative of energy stores and potential energy available for metabolic processes. In marine ecosystems, stingrays occupy the mesopredator niche, facilitating nutrient transfer from lower to higher trophic positions. Stingrays consume a variety of prey items ranging in lipid content, but how lipid metabolites …
Habitat Use Of Wintering Henslow's Sparrows (Centronyx Henslowii) In Power Line Right-Of-Ways, Abigail W. Dwire
Habitat Use Of Wintering Henslow's Sparrows (Centronyx Henslowii) In Power Line Right-Of-Ways, Abigail W. Dwire
Electronic Theses and Dissertations
Habitat loss and degradation are the leading causes of grassland bird declines worldwide. The Henslow’s Sparrow (Centronyx henslowii; hereafter HESP) is a grassland bird species of conservation concern that has historically relied on the herbaceous ground-layer of longleaf pine savannas and similar habitats in the southeastern U.S. for food and shelter in the winter. However, due to human development, alterations of habitat, and fire suppression, only fragments of these habitats remain. Over the last decade, surveys have annually documented HESPs using power line right-of-ways (hereafter, ROWs) at several sites in the coastal plain of Georgia as alternative habitat for …
