Extensive range persistence in peripheral and interior refugia characterizes Pleistocene range dynamics in a widespread Alpine plant species (Senecio carniolicus, Asteraceae).
Bottom Line: DNA sequences have been deposited in GenBank under accession nos.FR796701–FR797793 and nos.HE614296–HE614583.

Mentions: A statistical parsimony network constituted of 35 plastid DNA haplotypes, and their geographic distribution are presented in Fig. 2a,b. The parsimony network of plastid DNA haplotypes revealed strong reciprocal differentiation among haplotypes pertaining to haplotype groups 1 and 3. The mean number of pairwise differences (π) calculated for sets of haplotypes of haplotype groups 1 and 3 amounted to 5.99 and 1.23, respectively (haplotype group 2 contains a single haplotype). The most frequent haplotype was H35 found in 53% of the investigated individuals throughout the distribution range except for its western third (Fig. 2b). Twelve further haplotypes (H17, H20, H21, H23, H25, H26, H28–H33) differed only in a single mutational step from H35 (together with H35 encompassing 71% of the investigated individuals). Most divergent were H1–H11, which were separated by at least 10 mutational steps from the other haplotypes. These haplotypes were present in 11% of the sampled individuals (Fig. 2b). Most outgroup haplotypes were similar to haplotypes H1–H11, but three haplotypes present in S. incanus and S. halleri were close to haplotypes H14 and H17 of haplotype group 3. No outgroup haplotypes were shared with the ingroup (Fig. 2a).
