Alpine Vegetation Communities and the Alpine-Treeline Ecotone Boundary in New England as Biomonitors for Climate Change
This study mapped and analyzed the alpine-treeline ecotone (ATE) boundary and alpine plant communities on the Presidential Range, New Hampshire and Mount Katahdin, Maine. These are sensitiveExpand
Effects of ozone and other pollutants on the pulmonary function of adult hikers.
With prolonged outdoor exercise, low-level exposures to O3, PM2.5, and strong aerosol acidity were associated with significant effects on pulmonary function among adults and had significantly greater air pollution-related changes in pulmonary function. Expand
Limitations of Laboratory Bioassays: The Need for Ecosystem-Level Testing
In its responsibility to evaluate the potential effects of chemical substances proposed for release into the environment, the Environmental Protection Agency (EPA) faces profound challenges. TheExpand
Two new ground-level cloud water sampler designs which reduce rain contamination
Abstract The ability to obtain discrete samples of cloud water for chemical analysis during periods when precipitation is occurring is important for studies of potential ecological effects of cloudExpand
Light control of evening vertical migrations by Chaoborus punctipennis larvae
The close relationship between the rate of relative change in light intensity and the rates of upward movement including the afternoon drift supports the stimulus-velocity hypothesis that once larvae leave the sediments the speed and direction of the migration pattern is primarily regulated by relative light changes.

Evidence of Climate Change Declines with Elevation Based on Temperature and Snow Records from 1930s to 2006 on Mount Washington, New Hampshire, U.S.A
Mount Washington, New Hampshire, has the longest northeastern U.S. mountain climatological record, both at the summit and at Pinkham Notch, and Pinkham exhibits more climatic change than the summit but less than regional lower elevations. Expand
Establishing Alpine Research Priorities in Northeastern North America
Abstract Research in alpine areas of northeastern North America has been poorly coordinated, with minimal communication among researchers, and it has rarely been multidisciplinary. A workshop wasExpand
Limited alpine climatic warming and modeled phenology advancement for three alpine species in the Northeast United States.
Modeled trends in phenological advancement and sensitivity for three northeastern alpine species are less pronounced compared with lower elevations in the region, and this small shift in flower timing did not increase risk of frost damage. Expand
New perspectives in ecotoxicology
The task of regulating potentially harmful chemicals in the environment is presently hindered by the lack of appropriate concepts and methods for evaluating the effects of anthropogenic chemicals onExpand
A regional acidic cloud/fog water event in the eastern United States
Cloud and fog water constitutes an important hydrological input to specific ecosystems1–3. Recently, questions have been raised about the chemical composition of clouds and fog with reference toExpand
