  1. A DIVERSITAS BioGENESIS Workshop Roots, Branches, and Leaves: Integrating the Tree and Barcodes of Life April 19-20, 2007 National Evolutionary Synthesis Center, NC ORGANIZERS: C. Cunningham, M. Donoghue, D. Schindel, J. Cracraft, R. Hanner, L. Katz, S. Tillier PARTICIPANTS: 43, mostly USA SUPPORT: Sloan, DIVERSITAS, NESCent Yale Peabody Museum

  2. Finding Common Ground • TOL, BOL both mega-projects of practical value • Sharing materials -- collecting, storage, access • Coordinating informatics efforts -- standards • Markers (reconciling uni- vs. multi-locus) • Best practices, joint ethical code (one voice) • Culture of science -- big vs. small science, credit • Training/capacity-building Yale Peabody Museum

  3. Research Intersections/Opportunities • TOL+BOL=DOL (Diversity of Life) • Macro-micro intersection -- filling in the middle, “mesoscale” studies • Rates of evolution (phenotypic, molecular), patterns of speciation, diversification • Models spanning levels -- clade, region, environ Yale Peabody Museum

  4. Allopolyploid speciation in Persicaria (Polygonaceae) Diploids Tetraploid cpDNA nrITS “Leafy” 2nd Intron S-T. Kim and M. Donoghue Yale University

  5. Diploids Tetraploids Allopolyploid speciation in Persicaria (Polygonaceae) S-T. Kim and M. Donoghue, Yale University “Leafy” 2nd Intron Problem for barcoding: Recent allopolyploids identified as their maternal parent by cpDNA markers Nuclear marker? nrITS?, but homogenization
