Structural framework of the Appalachian Plateau of central West Virginia
The Appalachian basin has attracted great interest recently due to the gas potential from the Marcellus Formation. 2D seismic data has brought new insights to areas, particularly Webster County, WV, that were once considered low potential due to the lack of knowledge of the deep structures in the …

Stand dynamics and disturbance history of five oak -dominated old -growth stands in the unglaciated Appalachian Plateau
Stand dynamics and disturbance histories of five eastern, oak-dominated old-growth stands were investigated using ecological field sampling techniques, dendrochronologogical methods, and a review of historical resources of original forest composition and patterns of human and natural disturbance. …

Performance of northern red oak (Quercus rubra) underplantings under five management regimes and across existing environmental gradients
… provinces included the Ridge and Valley and Appalachian Plateau. The direct relationships between seedling performance and light as well as light and stand structure are also addressed. Seedling growth and survival are found to be driven by a combination of factors. The interaction of …

The vascular flora of Breaks Interstate Park, Pike County, Kentucky, and Dickenson County, Virginia
… northeastern terminus of Pine Mountain along the Appalachian Plateau. A total of 118 families, 341 genera, and 549 species, varieties, and subspecies were documented from Breaks Interstate Park. Six main vegetative communities were described: mesophytic forest, upper slopes and ridgetops, …

Predicting Regeneration in Appalachian Hardwood Stands Using the REGEN Expert System
… the REGEN regeneration prediction model to the Appalachians of Virginia and West Virginia. REGEN generates predictions via expert created REGEN knowledge bases (RKBs) that contain competitive rankings and stochastic parameters for selected species and size classes of advance reproduction. We …

The Vascular Flora Of The Red River Gorge In Powell, Menifee, And Wolfe Counties Kentucky
… of Kentucky. This area is in the Cumberland Plateau Physiographic Section which is a southern subsection of the Appalachian Plateau Physiographic Province. It is a mecca of outdoor recreation, hosting thousands of visitors each year, while also being home to a unique flora worthy of continued …

Morphological, Molecular, and Biogeographical Variation within the Imperiled Virginia Spiraea
… shrub endemic to the southern Blue Ridge and Appalachian Plateau physiographic provinces. Populations of S. virginiana are found restricted to scoured sections of high gradient streams within the Ohio River drainage. Present evidence indicates the species is reproducing asexually, most …

Hydrogeology and geomorphology of two structurally dissimilar terranes in Pennsylvania
… regimes than those in the relatively undeformed Appalachian Plateau.</p><p>The separate effects of geologic structure and lithology on groundwater regimes can be evaluated quantitatively on the basis of a single geomorphic parameter, the hypsometric integral. In the study area the integral is …

Characterizing and modeling wet stream length dynamics in Appalachian headwaters
… multiple spatial and temporal scales across the Appalachians. I mapped wet stream length in four Appalachian physiographic provinces--the Appalachian Plateau, Blue Ridge, New England, and Valley and Ridge--to characterize seasonal expansion and contraction of the wet network at a broad, regional …

Thermal and Diagenetic Evolution of Carboniferous Sandstones, Central Appalachian Basin
… of Carboniferous sandstones in the central Appalachian basin has been resolved using various techniques. Paleothermometers including vitrinite reflectance and fluid inclusions indicate that burial of Lower and Upper Pennsylvanian strata of the Appalachian Plateau in West Virginia exceeded …

Glacial geology of the Western Catskills
<p>Ic0 flow directions on the glaciated Appalachian Plateau in central New York were from the Adirondack Hountains. This is demonstrated by both striae directions and erratic provena..-1ce studies. No evidence for more than one Wisconsin glaciation as suggested by Rich (1935) could be found. …

Crustal structures and the Eastern extent of the Lower Paleozoic Shelf Strata within the Central Appalachians: a seismic reflection interpretation
… Paleozoic and Mesozoic structures within the Appalachian foreland, Blue Ridge, and Piedmont of the central Appalachians. The eastern portion of PR3 can be correlated along strike with the western portion of line 1-64, reprocessed earlier at Virginia Tech. The 1-64 seismic reflection data …

Effects of Alternative Silvicultural Treatments on Regeneration in the Southern Appalachians
Harvesting practices in the southern Appalachians have moved away from clearcutting in favor of variable retention harvesting systems. A study was initiated in 1995-8 to investigate the effects of retaining varying numbers of residual trees on regeneration in seven silvicultural treatments. A …

Subsurface study of the Lee formation in Buchanan County, Virginia
… southwest Virginia at the eastern margin of the Appalachian Plateau, is underlain by gently dipping Pennsylvanian formations. The lowest Pennsylvanian Lee Formation is exposed in an area of only 0.3 of a square mile, but information on its character and thickness has been obtained from wells …

Post-Orogenic Thermal History and Exhumation of the Northern Appalachian Basin: Low-Temperature Thermochronologic Constraints
… tectonics in the Paleozoic which formed of the Appalachian Orogen and the foreland basin has been a subject of considerable study. The objective of this dissertation is to apply low-temperature thermochronology to constrain the post-orogenic thermal history and exhumation of the Northern …
