FIGURE 5 in A phylogeny and evolutionary natural history of mesoamerican toads (Anura: Bufonidae: Incilius) based on morphology, life history, and molecular data
FIGURE 5. Bayesian analyses of the non-molecular (44 characters) and molecular data (5,898 bp) combined. Analyses were run for 50 x 106 generations, sampling every 1000, with the first 10,000 trees discarded as burn-in, posterior probabilities are shown for branches supported by> 0.50. The taxon Incilius sp. nov. is described by Mendelson et al. (in press).
FIGURE 4 in A phylogeny and evolutionary natural history of mesoamerican toads (Anura: Bufonidae: Incilius) based on morphology, life history, and molecular data
FIGURE 4. Parsimony analyses of the combined non-molecular (44 characters) and molecular data (5,898 bp). A strict consensus of two trees is shown, with bootstrap values> 50 based on 1000 replicates, with 100 random additions per replicate. The taxon Incilius sp. nov. is described by Mendelson et al. (in press).
FIGURE 3 in A phylogeny and evolutionary natural history of mesoamerican toads (Anura: Bufonidae: Incilius) based on morphology, life history, and molecular data
FIGURE 3. Bayesian consensus of the combined mtDNA and nuclear data (5,898 bp). Analyses were based on 50 x 106 generations, sampling every 1000, with the first 10,000 trees discarded as burn-in, posterior probabilities are shown for branches supported by> 0.50. The taxon Incilius sp. nov. is described by Mendelson et al. (in press).
FIGURE 6 in A phylogeny and evolutionary natural history of mesoamerican toads (Anura: Bufonidae: Incilius) based on morphology, life history, and molecular data
FIGURE 6. Summary hypothesis for the phylogenetic relationships among all known species of Incilius. Taxa indicated by an asterisk (*) and dashed lines were not included in our analyses because of lack of material available; their positions shown here are tentative, based on other lines of evidence (see Discussion). We hope that samples of these missing taxa may become available in the future, so that this hypothesis may be tested. The taxon Incilius sp. nov. is described by Mendelson et al. (in press).

FIGURE 2. Parsimony analyses of the combined mtDNA and nuclear data (5,898 bp). A strict consensus of two trees is shown, with bootstrap values> 50 based on 1000 replicates, each with 100 random additions per replicate. The taxon Incilius sp. nov. is described by Mendelson et al. (in press).
FIGURE 1 in A phylogeny and evolutionary natural history of mesoamerican toads (Anura: Bufonidae: Incilius) based on morphology, life history, and molecular data
FIGURE 1. Parsimony analysis of the non-molecular data (44 transformation series; Appendix III). Shown here is the strict consensus tree of the 149 equally most parsimonious trees (170 steps; CI = 0.353; RI = 0.637). Bootstrap values are shown above nodes, decay indices are shown below. We note the lack of basal resolution within the clade containing the "Forest toads" (e.g., Incilius campbelli, I. macrocristatus, etc.), and especially the position of Rhinella marina that renders Incilius paraphyletic.
