New NSF Funding to Study the Catastrophic Mortality of Oak Forests on Martha’s Vineyard

Dead Oaks on Martha's Vineyard

Five thousand years ago, New England forests experienced a tumultuous upheaval. Across the region's interior an abrupt and massive decline of hemlock occurred, and the dominant tree was replaced by hardwood species. Simultaneously, on Cape Cod and the Islands, oak experienced heavy mortality and was replaced by beech. The driver of these coincident changes was a warming climate and periods

New Harvard Forest Publication: Climate Change Shown in Paleo Record in Southwestern CT

Records of past environmental variability provide insights into how ecosystems respond to climate change. In a study published in the Journal of Quaternary Science, Harvard Forest researchers Wyatt Oswald, David Foster, Elaine Doughty, and Ed Faison analyze a lake-sediment record from southwestern Connecticut to reconstruct changes in climate, hydrology, and vegetation at the beginning and end of the Younger Dryas

New Harvard Forest Publication: Effect of Observers on Estimates of Infestation of Invasive Species

Hemlocks by stream

The growing threat posed by invasive species has focused increased attention on the importance of documenting the spread of introduced organisms. However, labor-intensive surveys are often required to monitor populations of invasive species and thus methods have been developed to estimate the true extent of an invasion using a sample of sites. In a new publication, postdoctoral fellow Matt Fitzpatrick

2009-2010 Harvard Forest Bullard Fellows in Forest Research

Harvard Forest is pleased to announce the 2009-2010 Charles Bullard Fellows in Forest Research. The purpose of this fellowship program, established in 1962, is to support advanced research and study by persons who show promise of making important contributions, either as scholars or administrators, to forestry defined in its broadest sense as the human use and study of forested environments.

Pitcher plants in the presses and on the road

Recent Harvard Forest post-doc Jim Karagatzides has published two papers based on his research with Harvard Forest Senior Sarcenia with Quaker MothEcologist Aaron Ellison. In the first, using stable isotope tracers in the field, Jim showed that Sarracenia purpurea can acquire nitrogen directly from amino acids, bypassing the inorganic nitrogen cycle on which

Harvard Forest to study impacts of Asian Longhorned beetle

Harvard Forest scientists Dave Orwig and David Foster were recently awarded a USDA Forest Health Management Cooperative Agreement to study vegetation data and associated tree cores from a forested area that was recently infested with an invasive pest, the Asian longhorned beetle (ALB; Anoplophora glabripennis). This invasive insect was recently discovered in Worcester, MA and is a serious threat to
