Figure 2. Principal Component Analysis of AFLP data from the Arabidopsis arenosa species complex.

Figure 2

Each symbol represents an individual. A: Visualization according to geographic regions. 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). These regions are illustrated in Figure 1. B: Visualization according to taxonomy. Arabidopsis arenosa var. intermedia is marked with an asterisk. C: Visualization according to ploidal level. Data lacking ploidal level estimates are marked in grey.
