A new paleoecology study by Emerson College/HF scientist Wyatt Oswald and HF director David Foster describes multiple episodes of eastern hemlock population decline ~6,000 years ago in New England. These events precede a major and more often-studied hemlock population decline 5,500 years ago. All of the decline events coincide with indicators of abrupt climate change. The sensitivity of hemlock populations,

A recent book by Jerry Jenkins, former Bullard Fellow, warns of the effects of climate change on the biodiversity of the Adirondack Mountain region. A New York Times book review assesses the book and profiles the author.

On November 1-2, 2011 ecosystem scientists from four northeastern LTER sites met at the Harvard Forest for a workshop with policy and media experts to explore new approaches for expanding the impact of science in environmental decision making. Under the leadership of representatives from Harvard Forest, Hubbard Brook, Cary Institute, The Ecosystems Center/MBL, Syracuse University and the University of New Hampshire,

A new paper published in Quaternary Research by Emerson College professor Wyatt Oswald and Harvard Forest director David Foster describes changes in climate and ecosystems in southern New England over the last 3,000 years. The researchers analyzed pollen and spores in a lake-sediment core from Little Pond in the town of Bolton, Massachusetts, and found evidence for three periods of
