FIG. 1 in A New Species of Monodelphis (Didelphimorphia: Didelphidae) from the Brazilian Amazon
FIG. 1. Phylogenetic relationships of species of the subgenus Mygalodelphys based on a maximum-likelihood analysis of DNA sequence data from one mitochondrial and four nuclear genes (4983 aligned sites; after Pavan et al., 2014). Support statistics from maximum-parsimony (MP) and maximum-likelihood (ML) bootstrap analyses are indicated at each resolved node along with Bayesian posterior probabilities (BPP). White wedges indicate MP and ML bootstrap frequencies ≤50%, gray indicates bootstrap frequencies between 50% and 75%, and black indicates bootstrap frequencies ≥75%. For Bayesian statistics, white indicates BPP <0.95, whereas black indicates BPP ≥0.95.
