Neighbour-joining tree of the combined observed NADH-5 – ATP-8 sequences. Sequences obtained in this study are marked with a star and their labels indicate their haplotype and, between parentheses, their localities. Additional sequences from Chile, Bolivia and Brasil were previously released by Johnson et al. (1998) and Napolitano et al. (2008), and their labels correspond to individual identification numbers. For each cluster, the correspondent clades of the HVS-I are indicated for the individuals sequenced in this research, as well as the geographical origin of the samples analysed by the other authors. Only bootstrap values over 50%of 1000 bootstraps are shown, corresponding to the NJ/ML analyses. Two ocelots (Lpa11 and Lpa31) and two margays (Lwi22 and Lwi36), from Johnson et al. (1998), were used as outgroups.
