Fig. 3 in The complete mitochondrial genome of Corydoras nattereri (Callichthyidae: Corydoradinae)

Fig. 3. Maximum likelihood tree (log likelihood = -2410.0522) of Corydoras samples with at least 90% similarity to the mitochondrial cytochrome oxidase I sequences of C. nattereri from the rio Suruí. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. Bootstrap robustness is indicated next to selected branches. Samples of C. nattereri have the locality name appended to the sample ID (those for which mitogenomes were produced are from de rio "Surui"), outgroups have the genus name and other samples of Corydoras have the species epithet name appended to the ID code (Table 1).

Fig. 2. Sequencing depth over the complete mitogenomes of the three individuals of Corydoras nattereri: KT239008 (A), KT239009 (B), and KT239010 (C). Read counts (y-axis) are shown in logarithmic scale and sharp decreases correspond to the punctuation model of mitochondrial transcription (positions correspond to those shown in Fig. 1 and Table 3). Black vertical bars indicate position of gaps that were filled with Sanger sequencing (Table 2). Reads were mapped to the mitogenomes using Bowtie and visualized at the Integrative Genome Viewer (IGV, Bernt et al., 2013; Thorvaldsdóttir et al., 2013).
