Relative importance of mechanisms
Basic question: What is the relative importance of different characteristics/processes in effecting invasion success (e.g. how important is biotic resistance relative to other processes?)
We did not come up with ways for the RCN to address this directly in the short run with our resources. However, Dana Blumenthal, Cini Brown, and Kat Shea have put in a proposal for a symposium at the Ecological Society of America in 2007 where speakers will address the relative importance of top-down and bottom-up forces in plant invasions.
