Time-calibrated phylogeny and ancestral range reconstruction of the subfamily Sigmodontinae.

Divergence ages were estimated using BEAST relaxed-clock model; node bars are 95% highest probability density credibility intervals. Pie charts represent the marginal probability of ancestral ranges reconstructed for each node of the phylogeny using S-DIVA; stripped diagonals indicate ancestral ranges of two areas and nodes with maximum probability reconstructions are downsized for clarity. Posterior clade probabilities are depicted with circles at the nodes with PP ≥ 0.95 (white) and PP ≥ 75% (gray). Node numbers correspond to fossil calibrations listed in Table S2. (A) Sigmodontinae crown; (B) Sigmodontalia; (C) Oryzomyalia.
