Fig. 10 Maximum likelihood (ML) phylogenetic tree from entire mt genomes (14,935 bps). The sequence alignment was put though Gblocks to remove regions with alignment gaps.Tip labels indicate NCBI accession numbers and (Barker & Barker Collection reference nos.). Numbers above branches show maximum likelihood bootstrap support, whereas numbers below branches show the Bayesian posterior probability support. Ixodes pavlovskyi Pomerantzev, 1946, one of the species "Other Ixodes" (sensu Barker & Murrell, 2004), for which an entire mitochondrial (mt) genome was available in GenBank, was set as the outgroup. The scale bar indicates 0.06 nucleotide substitutions per nucleotide site for the 14,935 nucleotide sites in our alignment of theses entire mt genomes. So, for example, there were about 896 nucleotide substitutions along the branch that leads to I. (Ceratixodes) uriae plus I. (Sternalixodes) holocyclus plus I. (Exopalpiger) fecialis, which is marked with an asterisk [i.e. 0.06 nucleotide substitutions per nucleotide site × 14,935 nucleotide sites (bps) = 1896 nucleotide substitutions]. Ticks in bold were sequenced in the present study
