Glacial History Affected Phenotypic Differentiation in the Alpine Plant, Campanula thyrsoides
Figure 2
Response to clipping of Campanula thyrsoides plants from 21 populations grown in a common garden.
Populations are ordered by phylogeographic region for (a) number of leaves, (b) maximum inflorescence height, (c) number of flowers, and (d) above-ground biomass. Filled circles indicate means of control plants, open circles indicate means of clipped plants. Error bars (grey) indicate standard errors (±1 SE) based on family means. WA – Western Alps; CSA – Central Swiss Alps; CAA – Central Austrian Alps; SEA – South-eastern Alps.
