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

SUPPORT: Sloan, DIVERSITAS, NESCent

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-buildingYalePeabody Museum
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
