FIGURE 1. Maximum likelihood tree (ln = -6500.1432) resulting from the analysis of cytochrome b gene sequences of Oligoryzomys species. Numbers indicate bootstrap values of the adjacent node retrieved in the maximum likelihood (left to the diagonal) and maximum parsimony (right to the diagonal) analyses. A less-than sign (<) indicates that the given clade receives less than 50 % of Bootstrap either in the ML and/or MP analyses. A dash (-) indicates that in the MP analysis that clade was not recovered. GenBank accession numbers of analyzed sequences are included at terminal labels; in addition, specimen numbers are provided for O. brendae.
