I don't think my talk at Ringberg Castle next week is open to the public, but these departmental seminars probably are:
Sept. 27, Kellogg Biological Station, Michigan
Oct. 4, St. Thomas University, Minnesota
Oct. 11, Oberlin College, Ohio
Oct. 30, Horticulture Department, University of Minnesota
Nov. 21, Iowa State University
Talk titles are mostly something like:
"Darwinian agriculture: evolutionary tradeoffs as opportunities"
