New Harvard Forest Publication: Spread and Distribution of Two Invasive Species

Spread and Distribution of Two Invasive Species across Southern New England

Forest ecologist David Orwig along with collaborators Evan Preisser (University of Rhode Island), Alexandra Lodge (Summer 2005 Summer Research Program student- Kenyon College), and Joe Elkinton (Umass, Amherst) report on the spread and distribution of 2 invasive species (hemlock woolly adelgid-HWA and elongate hemlock scale-EHS) across southern New England. This

New Harvard Forest Publication: Water Use in Hemlocks and Oaks

Water Use by Oak versus Hemlock: Implications for Ecosystem-level Effects of Hemlock Woolly Adelgid

The major significance of this paper is that it shows that a red oak-dominated forest, common in many areas of southern New England, uses more water in summer than an old-growth hemlock forest. As a result, if hemlocks that are killed by the hemlock woolly adelgid are

New Harvard Forest Publication: Mangrove Management Activities

In June 2006, Harvard Forest Senior Ecologist Aaron Ellison delivered the keynote address at the 2nd Meeting on the Mangrove Macrobenthos. Selected papers from this meeting have just been published in the Journal of Sea Research. In the lead paper, Ellison addresses mangrove management activities in the broader context of the diversity of animals such as crabs and prawns that

New Harvard Forest Publication: Invasive Species Distribution and Historical Land Use

Despite the recognized importance of historical factors in controlling many native species distributions, few studies have incorporated historical landscape changes into models of invasive species distribution and abundance. We surveyed 159 currently forested sites for the occurrence and abundance of Berberis thunbergii (Japanese barberry), an invasive, non-native shrub in forests of the northeastern U.S., relative to modern environmental conditions, contemporary

New Harvard Forest Publication: Prey Availability and Its Effect On Carnivorous Plants

Former Harvard Forest Bullard Fellow Elizabeth Farnsworth and Harvard Forest Senior Ecologist Aaron Ellison examine scaling relationships among leaf traits of 10 species of pitcher plants (Sarracenia species) fed different quantities of insect prey. Increased prey availability increased photosystem efficiencey (as expressed by the ratio of Fv/Fm), chlorophyll content, and photosynthetic rate. It also led to a shift from P-
