FIGURE 1 in Molecular phylogeny of long-tailed shrews (genus Sorex) from México and Guatemala

FIGURE 1. Phylogenetic relationships among long-tailed shrews of the genus Sorex from Mexico based on 77 mtDNA sequences of the cytochrome b gene. The tree represents the Bayesian analysis estimated through 6,000,000 generations. Numbers on branches indicate posterior probability values of nodal support. The numbers in parenthesis refer to the localities of samples from México (see Fig.3). Symbols point to the ancestral nodes of primary clades: A–B (●), A (□), B (․). * Not yet classified to either subgenera Sorex or Otisorex (see Table 1).
