Mountaintop Mining Consequences
Damage to ecosystems and threats to human health and the lack of effective mitigation require new approaches to mining regulation. There has been a global, 30-year increase in surface mining (1),Expand

Forest to reclaimed mine land use change leads to altered ecosystem structure and function.
The United States' use of coal results in many environmental alterations. In the Appalachian coal belt region, one widespread alteration is conversion of forest to reclaimed mineland. The goal ofExpand

Changes in the extent of surface mining and reclamation in the Central Appalachians detected using a 1976-2006 Landsat time series
Abstract Surface mining and reclamation is the dominant driver of land cover land use change (LCLUC) in the Central Appalachian Mountain region of the Eastern U.S. Accurate quantification of theExpand

A general Landsat model to predict canopy defoliation in broadleaf deciduous forests
Abstract Defoliation by insect herbivores can be a persistent disturbance affecting ecosystem functioning. We developed an approach to map canopy defoliation due to gypsy moth based on siteExpand

Temporal patterns of nitrogen leakage from mid‐Appalachian forested watersheds: Role of insect defoliation
Fluxes of dissolved nitrogen (N) as nitrate from forested watersheds in the mid-Appalachian region have important water quality ramifications for small acid-sensitive streams and for downstreamExpand

The role of soil water in stormflow generation in a forested headwater catchment: synthesis of natural tracer and hydrometric evidence
Quantifying the role of soil water in stormflow generation is a difficult but important goal for addressing catchment scale environmental problems. The purpose of this study was to combine naturalExpand

Change in the acid-base status of an appalachian mountain catchment following forest defoliation by the gypsy moth
Infestation by the gypsy moth (Lymantria dispar) can alter biogeochemical conditions in affected catchments. Stream-water concentration data obtained over the period of 1980–1993 for White Oak Run, aExpand

The influence of substrate quality and stream size on wood decomposition dynamics
Woody materials decayed more rapidly in a first order stream than in larger streams in eastern Quebec, Canada. The rate of annual mass loss (k) was highest (k=1.20) for alder wood chips in a firstExpand

Surface water quality is improving due to declining atmospheric N deposition.
We evaluated long-term surface water nitrate and atmospheric nitrogen (N) deposition trends for a group of nine predominantly forested Appalachian Mountain watersheds during a recent multidecadalExpand
