Dr. Kelchner gives an invited talk in the Netherlands, at the meeting "Genealogical Phylogenetic Networks in Evolutionary Biology". It was pleasant to be back at Leiden University. Particular thanks go to David Morrison, Axel Janke, Céline Scornavacca, Jim Whitfield, and Mike Steel for their pleasant company and impressive tolerance of Kelchner's giardia and entamoeba infections. That's real friendship.
