Figure 2: Bayesian (BI) tree computed using modern/GenBank (Supplementary Tables S1 and S4) haplotypes (H, 1,131 bp-long sequence alignment) and H. maculicollis as outgroup.

Maximum Likelihood (ML) and Neighbour Joining (NJ) methods produced perfectly overlapping reconstructions. Hence, the statistical support was reported at each node as follows: above, posterior probability value computed in the BI analysis; below, bootstrap percentage values computed in the ML (left) and NJ (right) trees. *A. cinereus haplotypes (H13 to H15) from L. perspicillata otters sampled in Singapore.
