Differentiation in phenotypic traits and molecular markers among and within phylogeographic lineages of Campanula thyrsoides.

QRT – quantitative genetic differentiation (95% CI) among four phylogeographic regions; QSR – quantitative genetic differentiation (95% CI) among 21 populations within four regions; F'RT – molecular differentiation (95% CI) among four phylogeographic regions based on microsatellite data; F'SR – molecular differentiation (95% CI) among 21 populations within four regions based on microsatellite data; ↓– unifying selection in phenotypic trait; ↑– diversifying selection in phenotypic trait; ns – non-significant difference between phenotypic trait and molecular differentiation; QRT vs. QSR: ns – non-significant difference between differentiation during glaciation and after postglacial recolonisation; QRT > QSR – significantly larger differentiation during glaciation than after postglacial recolonisation; QRT QSR – significantly larger differentiation after postglacial recolonisation than during glaciation.
