Climate May Keep Beautiful Killer Plant (Purple Loosestrife) in Check: University of Toronto Research (Feb 26, 2010)
University of Toronto.
Canadian scientists have found that adapting to northern climates carries a severe reproductive penalty for purple loosestrife, that may limit its spread. As the plant has spread north, it has run into challenges posed by a shorter growing season, including early flowering resulting in smaller sizes and reduced seed production.

Federal Funds Will help efforts to slow the Emerald Ash Borer invasion in Michigan and Beyond (Feb 19, 2010)
Michigian State University. College of Agriculture & Natural Resources.
All ash trees in North America could eventually be lost to the emerald ash borer (EAB), an exotic pest from Asia first discovered in Michigan and Canada in 2002. In an effort to develop strategies for managing recent infestations of EAB, state and federal forest specialists and researchers have been awarded $2.2 million from the federal American Recovery and Reinvestment Act of 2009 (ARRA) for a pilot project in Michigan's Upper Peninsula. The project, called SLAM, is designed to SL.ow A.sh M.ortality.

Does Climate Change Promote Invasive Species? (Feb 3, 2010)
Harvard Magazine.
Researchers have found that non-native plants, and especially invasive species, thrive during times of climate change because they're better able to adjust the timing of annual activities like flowering and fruiting. The study Favorable Climate Change Response Explains Non-Native Species' Success in Thoreau's Woods used a dataset that began with Henry David Thoreau’s cataloging of plants around Walden Pond in the 1850s, and where the average annual temperature has increased by about four degrees Fahrenheit.
