Fig. 3 in Spatial pattern of intraspecific mitochondrial diversity in the Northern Carpathian endemic spring snail, Bythinella pannonica (Frauenfeld, 1865) (Gastropoda: Hydrobiidae)

Fig. 3 Bythinella pannonica COI haplotype network. Circles Haplotypes occurring in the Karst (white) and in the Bükk Mts. (black). Circle sizes are proportional to the frequencies of the haplotypes. Haplotypes were nested into hierarchical clades following the rules of Templeton et al. (1987) and Templeton and Sing (1993). The two main clades, which could not be connected at the 95 % confidence level, are considered as distinct 4-step clades. For reasons of simplicity, only 2nd and higher step clades are indicated here. See Table 4 for phylogeographic inferences

Fig. 2 in Spatial pattern of intraspecific mitochondrial diversity in the Northern Carpathian endemic spring snail, Bythinella pannonica (Frauenfeld, 1865) (Gastropoda: Hydrobiidae)

Fig. 2 Constrained Bayesian tree of Bythinella pannonica mitochondrial cytochrome c oxidase subunit I gene (COI) haplotypes. The tree was rooted by Bythinella austriaca (FJ028978) (not illustrated). Numbers at branches are Bayesian posterior probabilities. For reasons of comparability, 2nd and higher step clades, defined by nested clade analysis, are indicated. Posterior probabilities above 95 % are given only for 2nd and higher step clades (see Fig. 3 for nested clade structure). Note that clade 2–7 is inferred to be paraphyletic by this analysis. This tree has been deposited in the TreeBase (http://purl.org/ phylo/treebase/phylows/study/ TB2:S10789)
