Fig. 43 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 43. Strict consensus of four equally minimumlength maximum parsimony trees for cytochromeb haplotypes of Amazonian slender mouse opossums, Marmosops. Data are the initial 630 bp of sequence; the tree is rooted by comparison to species of Marmosa (data from Patton et al., 1996); branch lengths are proportional to the number of character changes.

Tree length = 530 steps; CI = 0.545; RI = 0.669.
