Seasonal activity patterns of bats in the Central Appalachians
… threats to bats are especially pervasive in the central Appalachian Mountains of the eastern United States: a fungal disease called White-nose Syndrome (WNS) and wind energy development. White-nose Syndrome has caused the death of millions of bats in North America, and multiple hibernating bat …

Impacts of Fire on Bats in the Central Appalachians
Fire occurrence was widespread in the central Appalachians pre-European settlement due to Native American ignition and occasional lightning strikes, and continued through European settlement. During this time, low to mixed severity burns supported a suite of ecological communities that were fire …

Stratigraphic Architecture and Paleogeography of the Juniata Formation, Central Appalachians
Late Ordovician (Cincinnatian) strata of the central Appalachians provide an opportunity to study the effects of both tectonics and eustasy within a foreland-basin setting. The Juniata Formation consists of red sandstones, siltstones, and shales that were deposited as part of an extensive …

Geochemistry and petrogenesis of the Catoctin Volcanic Province, central Appalachians
… other rift related magmas in the southern and central Appalachians, the 570 Ma age suggests a two stage rift event, the first one failed while the second succeeded at opening the Atlantic ocean basin.

Conservation and management of the Allegheny woodrat in the central Appalachians
The Allegheny woodrat occurs throughout the Appalachian Mountains, where it forms isolated colonies in rock outcrops, cliffs, and caves. Populations along the northern and western peripheries of the range have experienced drastic declines in the past 20--30 years. A paucity of ecological …

Stratigraphy, sedimentology, and diagenetic history of the Siluro- Devonian Helderberg Group, central Appalachians
… Late Silurian-Early Devonian Helderberg Group, Central Appalachians, is a sequence of mixed siliciclastic-carbonate sediments that was deposited during relative tectonic quiescence on a ramp that built out from low-relief tectonic highlands bordering the eastern side of the Appalachian Basin. …

An Integrated Geophysical Study of the Central Appalachians of Western Virginia and Eastern West Virginia
… km of industry seismic reflection data in the central Appalachians were reprocessed using both conventional and newly developed processing schemes. A new processing sequence, called dip projection, is introduced. The technique projects crooked-line processed CMPs onto a straight line oriented …

Origin, Architecture, and Thermal State of the Lackawanna Synclinorium, Pennsylvania: Implications for Tectonic Evolution of the Central Appalachians
Mapping of the Pittston quadrangle in the central domain and structural analysis elsewhere in the synclinorium reveal that mesoscopic faults, folds, and cleavage throughout the synclinorium trend ∼075°; thus, these structures parallel the southern domain, but trend at high angles to the …

Marine offshore to alluvial plain transitions within the "Chemung"-Hampshire interval (Upper Devonian) of the southern central Appalachians
… and Hampshire Formations of the southern Central Appalachian basin constitute the upper strata of an eastward thickening wedge of elastic sediment. The sediments comprising the "Chemung" and Hampshire, deposited on a low-gradient marine shelf and alluvial plain, respectively, are syn- to …

Population ecology of and the effects of hunting on ruffed grouse (Bonasa umbellus) in the southern and central Appalachians
… umbellus) population ecology in the southern and central Appalachians as part of the Appalachian Cooperative Grouse Research Project (ACGRP). Several hypotheses have been offered to explain the low abundance of ruffed grouse in the region including inadequate quantity of early-successional forests …

Biotic and Abiotic Factors of Picea rubens (Red Spruce) Seedling Regeneration in Disturbed Heathland Barrens of the Central Appalachians
During the late 19th and early 20th centuries, extensive logging reduced the forests of red spruce (Picea rubens) by nearly 99% through portions of West Virginia. In the wake of this disturbance, red spruce has begun regenerating on the ridge and mountaintop areas of Canaan Valley, West Virginia, …

Functional Equivalency of Created and Natural Wetlands in the Central Appalachians: Reproductive Success, Call Phenology, and Diet Composition of Amphibians
… were performed at 24 wetlands throughout the Central Appalachians once every month from March through August of 2009 and 2010. Occupancy modeling was used to estimate the occupancy and detection of individual species, incorporating relevant environmental variables. The occupancy of anurans did …

Crustal structures and the Eastern extent of the Lower Paleozoic Shelf Strata within the Central Appalachians: a seismic reflection interpretation
… 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 (12-fold) images the crust from the eastern Valley and …

Stratigraphic framework, structural evolution and tectonic implications of the eastern Blue Ridge sequence in the central Appalachians near Warrenton, Virginia
… workers have proposed tectonic models of the central Appalachians in which accreted terrane boundaries, are present along the eastern Blue Ridge. The continuous rift stratigraphy and the tectonic evolution proposed herein do not support such models.

Influence of the West Virginia Dome on paleocurrent patterns in the Upper Devonian-Lower Mississippian Price Formation in the Central Appalachians
… known as the West Virginia Dome located in the Central Appalachians of West Virginia. Paleocurrent data collected from the Price Formation demonstrates the significance of the dome on paleoflow patterns. Exposures in West Virginia are located along the Allegheny Front and include the lowermost …

U/Pb Zircon Ages of Plutons from the Central Appalachians and GIS-Based Assessment of Plutons with Comments on Their Regional Tectonic Significance

Silurian Conodonts from the Wills Mountain Anticline, Virginia, West Virginia, and Maryland
… along the Wills Mountain anticline in the Central Appalachians. Beds in the Central Appalachians formerly called the Rochester Formation have been renamed the Cosner Gap Member of the Mifflintown Formation. The type section of the unit is at Cosner Gap, northwest of Maysville, Granty Count, …

Ecological Benefits of Mitigation on a Large River Mainstem in an Intensively Mined Appalachian Watershed
<p>Large scale surface mining in the central Appalachians causes significant alteration of headwater catchments, and these impacts may be offset through implementation of stream restoration projects. As an example, several habitat enhancement structures (cross-vanes and j-hooks) were constructed …

Sedimentology and tectonic implications of the Late Proterozoic to Early Cambrian Chilhowee Group in southern and central Virginia
… undertaken in exhumed orogenic belts. In the central Appalachians, the Chilhowee Group records such an evolution. The Unicoi and basal Hampton Formations record the transition from rifting to opening of the Iapetus Ocean. The majority of the Hampton Formation and the overlying Erwin Formation …
