Not sure how easy it would be to sneak into this, but it sounded interesting to me.  If you're in Stumptown, are a member of the OAEP, and need a date, call me.

TOPIC: Widespread Increases in Tree Mortality Rates in the Western US: A Harbinger of Things to Come?

Dr. Harmon’s analysis of long-term, old-growth forest measurements indicate that tree mortality rates have increased rapidly in recent decades throughout the Western United States. Shifts in forest mortality rates can affect forest structure, composition, and ecosystem services (such as carbon sequestration). Mounting evidence suggests that these increasing tree mortality rates are not attributable to competition among trees or aging forests, but rather may be due climatic changes such as a trend in regional warming and hydrological changes. Recently published in Science, 323, 521 (January 2009), Dr. Harmon will discuss the latest research on increases in tree mortality rates in the Western US, the possible causes for this trend, and the implications of these findings on our future.
