phylogenetic relationships and classification of didelphid marsupials ...

2009 VOSS AND JANSA: DIDELPHID MARSUPIALS 71
Fig. 29. The tree resulting from maximum-likelihood analysis of the DMP1 dataset under its bestfitting
model (GTR + C, ln-likelihood 5 –5943.66; table 11). Four of the five deletion events that optimize
as synapomorphies on this topology are indicated with vertical gray bars; the fifth (not shown) is shared by
Marmosa regina, M. paraguayana, M. demerarae, M. murina, andM. lepida, but this clade is subtended by
a zero-length branch. Because alignable DMP1 sequences are not available from outgroup taxa (see text),
this tree is rooted with Glironia. Conventions for indicating nodal support are described in the caption to
figure 28. The broken arrow indicates the alternative position of Tlacuatzin recovered by ML bootstrap
analysis (the position for this taxon recovered by ML analysis of the original data was not supported
by bootstrapping).
