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 …
Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler
Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler
Graduate Theses, Dissertations, and Problem Reports
Soils in the Monongahela National Forest (MNF) are acidic due to sandstone parent material, acid deposition, uptake of base cations by vegetation, and release of organic acids by organic matter (OM) decomposition. Increases in soil acidity have caused declines in forest health and changed species composition and nutrient status. Liming can neutralize soil acidity, but no large-scale liming projects have been done on acid forest soils in the USA. In anticipation of acquiring funding for a proposed liming project in the MNF, in 2007 and 2009 10 sites were selected to sample and analyze soils before lime was applied. In …
A Two-Year Seasonal Analysis Of Wetland Vegetation At The Mcclintic Wildlife Management Area In Mason County, West Virginia, Anne Carrington Blankenship
A Two-Year Seasonal Analysis Of Wetland Vegetation At The Mcclintic Wildlife Management Area In Mason County, West Virginia, Anne Carrington Blankenship
Theses, Dissertations and Capstones
Disturbances play a key role in the structure of ecosystems. Most ecosystems are subject to several different disturbance regimes that occur at different temporal and spatial scales. Studying the effects of disturbances can lead to a better understanding of a vegetative community’s future productivity. However, in order to understand the effects of disturbance, a vegetative community should first be studied before the disturbance occurs. This study analyzes the composition and seasonal variations of vegetative communities in and around four ponds at the McClintic Wildlife Management Area in Mason County, West Virginia during two growing seasons prior to remediation activities in …
Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick
Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick
Theses, Dissertations and Capstones
Soil processes often exhibit spatial heterogeneity within ecosystems and this heterogeneity may influence community structure. This study was conducted to determine spatial patterns and variability of soil nutrients and plant communities within different vegetation types in a stream floodplain in southwestern West Virginia. One 5-m × 5-m site was established in each of three vegetation/drainage types: pasture (PA), old field (OF), and wetland scar (SC). Pasture and SC sites were located ~25 m apart on flat bottomland; the OF site was located on a moderate slope 6.3 m above bottomland, ~200 m from PA and SC. A 10-m × 1-m …
Computer Simulation For Feature Extraction In Pattern Recognition And Geobiophysical Modeling In Mountaineous Wetland Delineation, Natalie Ripsher
Computer Simulation For Feature Extraction In Pattern Recognition And Geobiophysical Modeling In Mountaineous Wetland Delineation, Natalie Ripsher
Theses, Dissertations and Capstones
Delineation of wetlands is an important aspect of protecting of these ecologically diverse and biocomplex habitats. Selected image-processing techniques are applied to remotely sensed imagery of Canaan Valley, in order to determine the best method of extracting wetland features for habitat delineation. Remotely sensed data from April 1997 and September 1999 were compared to determine the accuracy of feature extraction, and the effect of seasonal and long term climate change on wetland delineation. Pattern recognition for feature extraction was used to identify vegetation associations and changes in habitats. Computer simulation of the infrared band was performed using ER Mapper so …
