(a) Regional genetic differentiation and (b) genetic differentiation according to taxonomy, based on AFLP and chloroplast DNA sequence data (<i>trn</i>L/F suprahaplotypes).
<p>Sample size (<i>n</i>), Nei's gene diversity (<i>H<sub>E</sub></i>), proportion of variable markers (FP), and nucleotide diversity (<i>π</i>) with standard deviation are provided. For <i>trn</i>L/F suprahaplotypes effective genetic diversity according to Gregorius (<i>V<sub>a</sub></i>) is additionally displayed. The following seven geographic regions were considered: (1) Balkan Peninsula (Balk), (2) Carpathians (Carp), (3) unglaciated Eastern and Southeastern Alps (UnglaESEAlps), (4) glaciated Eastern Alps (GlaEAlps), (5) glaciated Western Alps (GlaWAlps), (6) unglaciated Central Europe (UnglaCentrEur), and (7) glaciated northern Europe (GlaNEur). <i>Arabidopsis arenosa</i> var. <i>intermedia</i> is integrated within <i>A. arenosa</i> subsp. <i>arenosa</i>. <i>Arabidopsis nitida</i> was omitted from the analyses, as it was represented by one (AFLPs) and three (<i>trn</i>L/F suprahaplotypes) accession(s) only.</p
