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

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

Butterflies and Climate Change

In this study, which was part of Shannon Pellini's (Harvard Forest Postdoctoral fellow) dissertation work under the advisement of Jessica Hellmann at the University of Notre Dame, Shannon and colleagues performed field and laboratory reciprocal translocation experiments with skipper (Erynnis propertius) and swallowtail (Papilio zelicaon) butterfly populations from Oregon and Vancouver Island. The aim of the study was to determine

Graphing Data from Schoolyard Research

Dr. Betsy Colburn Harvard Forest Schoolyard Science Program has completed Show Me a Picture, Tell Me a Story: An Introduction to Graphs for the Analysis of Ecological Data from Schoolyard Science Research Studies. This guide for teachers discusses the use of graphs to interpret ecological data collected in schoolyard research studies. The manual covers ways of organizing data,
