Donoghue7 1Florida Museum of Natural History, ABSTRACT University of Florida, Gainesville, FL, Aim The clade Campanulaceae in the Cretan area is rich in endemics, with c. 2National Evolutionary Synthesis Center, Durham, NC, 3Department of Ecology and 50% of its species having restricted distributions. These species are analysed in the Evolutionary Biology, Brown University, context of a larger phylogeny of the Campanulaceae. Divergence times are Providence, RI, USA, 4Department of calculated and hypotheses of vicariance and dispersal are tested with the aim of Molecular Biology (VI), Max Planck Institute understanding whether Cretan lineages represent remnants of an older for Developmental Biology, Tu¨bingen, continental flora. 5 Germany, Section of Integrative Biology and Location The Cretan area: Crete and the Karpathos Islands (Greece). Institute of Cellular and Molecular Biology, University of Texas, Austin, TX, USA, 6Botany Methods We obtained chloroplast DNA sequence data from rbcL, atpB and Department, Natural History Museum of matK genes for 102 ingroup taxa, of which 18 are from the Cretan area, 11 are Crete, University of Crete, Heraklion, Greece endemics, and two have disjunct, bi-regional distributions. We analysed the data and 7Department of Ecology and Evolutionary using beast, a Bayesian approach that simultaneously infers the phylogeny and Biology, Yale University, New Haven, CT, USA divergence times. We calibrated the tree by placing a seed fossil in the phylogeny, and used published age estimates as a prior for the root.
