Leveraging Herbaria Specimens: A New 3d Imaging Protocol And Analyses Of Diversity Of West Virginia Rosids, Zachary Scott Shamblin
Leveraging Herbaria Specimens: A New 3d Imaging Protocol And Analyses Of Diversity Of West Virginia Rosids, Zachary Scott Shamblin
Theses, Dissertations and Capstones
Herbaria are repositories of plant natural history, whose data can provide insights into the life histories of plant taxa over space and time. Recent initiatives to digitize herbarium data have made studies over broad geographic and taxonomic extents possible, with the ability of scientists to access data from large databases of herbaria. Most of the digitization initiatives have focused on flat 2D herbaria sheets, but herbaria also include 3D collections, such as fungi, mosses, lichens, and dry fruits. In Chapter 1 we propose an easy and cost-effective workflow that uses free photogrammetry software to produce 3D images of 3D herbaria …
The Future Of The Big Sagebrush Ecosystem: Plant Community Response To Grazing, Wildfire, And Invasive Annual Grass In A Changing Climate, Margaret Eleanor England
The Future Of The Big Sagebrush Ecosystem: Plant Community Response To Grazing, Wildfire, And Invasive Annual Grass In A Changing Climate, Margaret Eleanor England
Theses, Dissertations and Capstones
Climate change is increasingly affecting the plant communities across the world. In the Western United States, these changes are affecting plant communities and their risk of invasive species, as well as the frequency and severity of wildfire. Big sagebrush (Artemisia tridentata Nutt.) ecosystems of the Western United States are facing threats of increasingly frequent wildfire and invasion of the annual grass cheatgrass (Bromus tectorum L.), which may be exacerbated by global climate change. Past studies have found cheatgrass to exhibit a positive feedback loop with wildfire, and climate change is expected to facilitate expansion of the cheatgrass …
The Effects Of Endocrine Disrupting Chemicals On Plants, Christian Mathew Pridemore
The Effects Of Endocrine Disrupting Chemicals On Plants, Christian Mathew Pridemore
Theses, Dissertations and Capstones
Endocrine disrupting chemicals (EDCs) are a diverse group of chemicals which can have a detrimental effect on human health, affecting any physiological body system sensitive to hormonal changes. Human exposure to EDCs is inevitable due to their prevalence in modern living; EDCs are integral compounds found in everyday items with which humans interact and ingest. These, along with other indirect avenues leading to EDC exposure, pose a threat to both human health and to the health of wildlife and agricultural environments. Studies on the effects of EDCs on plants can be substantially informative and necessary for progress towards solving the …
Evaluating Potential Plant Hormone Cross Talk Between Auxin And Ethylene In Arabidopsis, Mia Lynne Brown
Evaluating Potential Plant Hormone Cross Talk Between Auxin And Ethylene In Arabidopsis, Mia Lynne Brown
Theses, Dissertations and Capstones
Auxin is the primary hormone responsible for plant growth and development. Regulation of auxin-response genes occurs through transcriptional activators (auxin response factors called ARFs) which bind to auxin response elements (AuxREs). Some auxin-responsive genes encode aminocyclopropane-1-carboxylic acid synthase (ACS) enzymes which regulate the production of the plant hormone ethylene. The major research objective was to evaluate transcriptional cross talk between auxin and ethylene. Both AuxREs and ethylene response elements were found in several ACS and ARF genes, suggesting cross talk between the two hormones at the transcriptional level. Analysis of transgenic Arabidopsis thaliana plants deficient in ARF7 and containing a …
A Vegetation Analysis Of Plant Communities In And Around Selected Holding Ponds At Mcclintic Wildlife Management Area, Mason County, West Virginia, Russell Bowman Shrader
A Vegetation Analysis Of Plant Communities In And Around Selected Holding Ponds At Mcclintic Wildlife Management Area, Mason County, West Virginia, Russell Bowman Shrader
Theses, Dissertations and Capstones
This study was conducted as an analysis of vegetation in and around four ponds at McClintic Wildlife Management Area (MWMA), located in Mason County, West Virginia. The MWMA is the former West Virginia Ordnance Works (WVOW), having served as a trinitrotoluene (TNT) manufacturing site from 1941-1946. Such history presents the area with unique conditions resulting in diverse types and amounts of plants, since any type of forest disturbance, regardless of cause, alters ecosystem functions. This project was originally designed as part of a groundwater pump-and-treat plan for MWMA, where potential impacts of groundwater removal to ponds and the associated plant …
Morphometric Analysis And Comparisons Of Electrophoretic Protein Profiles Of The Scutellaria Ovata Hill (Lamiaceae) Complex In West Virginia, Virginia And Ohio With Emphasis On Shale Barren Taxa, Eric W. Ewing
Theses, Dissertations and Capstones
Elements of the Scutellaria ovata complex in the eastern United States are reported to include S. ovata var. pseudoarguta, S. ovata var. rugosa, S. ovata var. virginiana and S. ovata ssp. ovata. All but S. ovata ssp. ovata occur in the shale barren habitat of eastern West Virginia and western Virginia. S. ovata var. pseudoarguta has been proposed as a threatened element in North America. A morphometric study of specimens collected in West Virginia, Virginia and Ohio was undertaken to determine which characters are most useful in separating taxa in the complex. Nineteen characters were assessed from 104 herbarium specimens …
Floristics, Plant Community Structure And Bank Profiles, For Five Sites Along The Middle Ohio River, Amy Nicole Morris
Floristics, Plant Community Structure And Bank Profiles, For Five Sites Along The Middle Ohio River, Amy Nicole Morris
Theses, Dissertations and Capstones
Plant community structure, floristics, and bank profiles for five sites along the middle Ohio River were described. Values obtained were compared with a similar study by Clagg and Mills in 1978 on four of the five sites. A total of 186 plant species was observed in the plant community and floristic study. Glenwood Bend had the greatest diversity with 109 plant species. Mason-Pomeroy had the lowest diversity with only 35 plant species. Six species, representing 3.2 percent of the total observed number of species, were present at all five sites. The majority of species, 51 percent, were present at only …
Flora And Vegetation Of Five Natural Wetlands In The Kanawha And Ohio River Floodplains, Southwestern West Virginia, Bernadine Phillips Brumfield
Flora And Vegetation Of Five Natural Wetlands In The Kanawha And Ohio River Floodplains, Southwestern West Virginia, Bernadine Phillips Brumfield
Theses, Dissertations and Capstones
Flora and vegetation were studied in five natural wetlands along the Kanawha and Ohio Rivers, southwestern West Virginia. Vegetation was analysed using a stratified-random approach with nested quadrats along line transects. The abundance of dead trees suggests an overall increase in water level with time. One to three canopy species comprise 75 percent of the Basal Area at all five sites. Acer rubrum and Quercus palustris are the dominant species at the Winfield East, Winfield West and Pt. Pleasant sites. Salix nigra is the dominant species at McCausland Run site and Acer saccharinum is dominant at the Guyan Creek Oxbow …
