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

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

Ants as ecological indicators

Harvard Forest Senior Ecologist Aaron Ellison spent a week at the beach, working with Parks Canada and the staff of Prince Edward Island (PEI) National Park on developing a monitoring protocol for using ant diversity as an indicator of ecological integrity of this coastal national park. The absence of exotic ants on PEI, but their presence in nearby Nova Scotia,

Prospect Hill Wireless Network

Prospect Hill Wireless Network

The Harvard Forest has received a grant from the National Science Foundation to build a wireless network across the 400-ha Prospect Hill Tract, providing high-speed network access to a wide range of short and long-term experimental sites. The network will make it possible to monitor and control instruments and to collect and analyze data in real time, effectively creating an
