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 …
Analyzing Thermal Gradients Using Terrestrial Laser Scanning In Scrub Oak Habitats, Alyssa Silbey
Analyzing Thermal Gradients Using Terrestrial Laser Scanning In Scrub Oak Habitats, Alyssa Silbey
Honors Theses
Thermal microclimates are an important component of natural ecosystems because they provide appropriate niche space for many organisms; however, they are not widely studied because of their small scale. Likewise, variation in these microclimates may significantly impact animal thermoregulation and plant physiological processes and be especially important in the face of climate change. The goal of this study is to determine how the size and structure of Quercus ilicifolia shrubs influences ground temperature gradients. We hypothesized that differences in leaf cover and leaf area index (LAI) would cause temperature under shrubs to cool relative to the ambient temperature, and that …
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 …
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 …
