FIGURE 2. Phylogenetic trees of the 828-bp fragment of the Cyt b gene generated from the analyzed Neotoma specimens. The numbers of haplotypes and subspecies at the tip of each branch follow Table 1. The trees were constructed using the 50% majority rule consensus algorithm (except in maximum-likelihood). Values in the nodes are branch support for the analyses. The N. leucodon sequence was included as the ingroup and N. picta, N. isthmica, and N. mexicana as the outgroup. (A) Maximum-likelihood tree using the GTR+I model; (B) neighbor-joining tree, genetic distances were calculated using the Jukes-Cantor model, percentage differences per node are in table 2. (C) Bayesian inference performed using the GTR+I model.

Figure 3. Best maximum likelihood tree based on analysis of the concatenated dataset of fragments of the mitochondrial genes 16S and COI using IQ-TREE. Ambiguous alignment sites in 16S were removed using MAFFT. Numbers on branches indicate nodal support based on 10 000 ultra-fast bootstrap repeats. Scale bar indicates 10% of modelled sequence divergence. Individual samples are named according to their initial identification. Pale green bars indicate a collection elevation of 300–600 m, dark green bars a collection elevation of> 600 m and no bars a collection elevation <300 m.
