Fig. 2From: Postglacial recolonizations, watershed crossings and human translocations shape the distribution of chub lineages around the Swiss AlpsMaximum likelihood phylogenetic tree of chub haplotypes obtained from concatenated mitochondrial COI and Cyt b sequences, based on the Tamura-Nei model [54]. Petroleuciscus borysthenicus and Rutilus rutilus are used as outgroups. Letters A to O are European chub (Squalius cephalus) haplotypes and P to W are from Italian chub (S. squalus). The tree is scaled with branch lengths indicating amino acid substitutions per site (see scale bar). Numbers at nodes represent percent bootstrap support from 1000 replications. Lower than 50 % support values are not shownBack to article page
