A Meta-Analysis Of The Human Uses Of Pteridophytic Species In Tennessee, Diana Sevier
A Meta-Analysis Of The Human Uses Of Pteridophytic Species In Tennessee, Diana Sevier
Honors Theses
Pteridophytes are an ancient lineage of plants, composed of ferns and fern allies, which are spread across the globe. There is also a long record of humans using pteridophytes to their benefit, which includes the broad categories of medicine, ornamentation, food, phytoremediation, and agriculture. Understanding these concepts, the goal of this thesis was to conduct a meta-analysis which pulled together data from many resources on the 94 Tennessee pteridophyte species to create a repository of human use information, as well as to examine, analyze, and comment on the trends present within and between taxonomic groups of pteridophytes. The methods used …
Meta-Analysis Of Biological Research Literature, Evan Suggs
Meta-Analysis Of Biological Research Literature, Evan Suggs
Honors Theses
Comparative studies have been powerful tools in generating a broad understanding about the evolution of animal social systems but they currently rely on the slow, manual process of reading thousands of abstracts and papers from research databases. A web application was created for researchers conducting a comparative survey, in order to speed up their research. This web application automates the retrieval of research papers and their selection process. Using previously obtained data sets on the orders Artiodacytla and Lagomorph, a machine learning application was created to classify the papers. These techniques and tools should greatly increase the speed at which …
Development Of An Auto-Bioluminescent Lung Cell Line For Evaluation Of In Vitro Effects Of E-Cigarette Compounds On Normal Cell Proliferation, Olivia Morrison
Development Of An Auto-Bioluminescent Lung Cell Line For Evaluation Of In Vitro Effects Of E-Cigarette Compounds On Normal Cell Proliferation, Olivia Morrison
Honors Theses
The effects of smoking have long been studied; however, with the rise of electronic cigarettes there is a growing interest in the effects of this smoking substitute. Marketed as a safer alternative to tobacco cigarettes, the popularity of electronic cigarette (e-cigarette) use has dramatically increased. This has demanded regulatory methods to be put into effect, however, scientific study is only beginning on the new fad to determine the impacts of its use on the human body. The present study aims to examine the biological effects of lung cell exposure to tobacco alkaloids found in electronic cigarette filling solutions. We hypothesize …
A Contribution To The Macrofungi Of Cloudland Canyon State Park, Peyden Valentine
A Contribution To The Macrofungi Of Cloudland Canyon State Park, Peyden Valentine
Honors Theses
I conducted a survey of the macroscopic fungi within Cloudland Canyon State Park, Dade County, GA that consisted of twenty-three forays from May through December of 2019, and one foray in March 2020. The results of my survey add baseline data to our knowledge of the mushrooms present within the park, allow for the future construction of an All Taxa Biodiversity Index, and allow comparisons to other surveys of fungal diversity in similar areas of the Cumberland Plateau: the Tennessee River Gorge Trust (Starrett 2005), and the Lula Lake Land Trust (De Guzman 2000). My survey resulted in an overall …
Canopy Openness As A Predictor Of Growth For Castanea Dentata Seedlings In The Cumberland Uplands Of Tennessee, Hannah Crawford
Canopy Openness As A Predictor Of Growth For Castanea Dentata Seedlings In The Cumberland Uplands Of Tennessee, Hannah Crawford
Honors Theses
Castanea dentata growth and reproduction in the forest ecosystem is limited by light. Canopy gaps could be used for restoration efforts; however, the lack of blight resistant planting material has limited what is known about the silvicultural requirements of C. dentata. I studied the survival and growth of chestnut seedlings in various sized light gaps in the Cumberland Uplands in the 2019 season. The Tennessee Chapter of the American Chestnut Foundation previously established Eagle Point Railroad (Cumberland Plateau) and the Starr Farm (Eastern Highland Rim), and I established a site near Barker Pounds trailhead (Cumberland Plateau). Results indicate that canopy …
Phospholipid Remodeling Via Exogenous Polyunsaturated Fatty Acid Uptake Modulates Stress Resistance In Vibrio Cholerae, William Strike
Phospholipid Remodeling Via Exogenous Polyunsaturated Fatty Acid Uptake Modulates Stress Resistance In Vibrio Cholerae, William Strike
Honors Theses
Antibiotic-resistant pathogens represent an escalating threat to public health worldwide, substantially increasing the burden of healthcare and community-acquired infections. Several factors contribute to the emergence and spread of this threat, including but not limited to improper antibiotic use and prescriptions in health-care settings and the community, increasing global travel and migration from countries that have higher levels of antibiotic-resistant pathogens, and a lack of new antibiotics under development. According to the World Health Organization, rising rates of resistance among Gram-negative bacteria (such as Vibrio cholerae) are of particular concern. These bacteria have evolved a number of endogenous membrane remodeling strategies …
A Contribution To The Characterization Of The Diversity Of Ectomycorrhizal Fungi Associated With American Chestnut At The Utc Fortwood Street Nursery, Colton Jones
Honors Theses
Ectomycorrhizas play several essential roles in the biosphere and have immeasurable implications on the ecosystems in which they exist. Much has been discovered about the relationships between ectomycorrhizal fungi and the trees with which they associate, but there is still much to learn. Due to the nature of ectomycorrhizal morphology, DNA analysis is frequently required in order to accurately identify the fungal partner. Some ectomycorrhizal fungi produce above-ground fruiting bodies that presumably contain the same DNA sequences as the fungi encapsulating corresponding plant root tips below the soil; these fruiting bodies have been frequently observed growing in nursery containers at …
