New Harvard Forest Publication: Ragweed and Historical Climate Change

The environmental drivers behind abundant ragweed pollen in sediments of four southern New England lakes 10,000-8000 years ago were investigated. They found strong evidence that high levels of ragweed pollen were associated with warmer, drier conditions. This conclusion is corroborated by independent lake level and climate reconstructions. Together, these results have implications for future ragweed distribution and abundance, and suggest

New Harvard Forest Publication: Predicting Species Abundance After Habitat Loss

Plant and animal population sizes inevitably change following habitat loss, but the mechanisms underlying these changes are poorly understood. In a new study published in PLoS Biology, University of Vermont biology professor Nicholas Gotelli and Harvard Forest senior ecologist Aaron Ellison provide the first experimental confirmation that trophic structure can determine species abundances in the face of habitat loss. In

New Harvard Forest Publication: Foliage Decomposition in Forests Affected By Hemlock Wooly Adelgid

Recent Research Assistant Richard Cobb, working with collaborators including Harvard Forest Ecologist David Orwig and former HF Summer Reserach Program student Steve Currie, examined the impacts of the introduced insect, the hemlock woolly adelgid (HWA) on green litter decomposition in New England hemlock forests. This study investigated both the direct effects of HWA feeding and indirect changes in microclimate on
