Fig. 98 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 98. Map of localities of members of the Oryzomys macconnelli group sampled for mtDNA cytochromeb sequences: left: O. nitidus (solid triangles) and O. legatus (open triangle); right: O. macconnelli (solid circles), O. emmonsae (solid pentagons), and O. russatus (solid squares). Localities from the Rio Juruá are numbered; other localities are given letters. Both letters and numbers correspond to the list of provenance and voucher specimen catalog numbers provided in table 36. The transition in geographic units of O. macconnelli across the Rio Solimes is indicated by the hiatus in the crosshatched distribution of the species. Distributions are based on Musser et al. (1998).

Fig. 97 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 97. Strict consensus tree of three equal minimumlength parsimony trees for haplotypes of the mitochondrial cytochromeb gene (801 bp; only 401 bp are available for the individual from Paraguay [Myers et al., 1995]) for members of the Oryzomys megacephalus complex of species. Length = 627 steps, CI = 0.593, RI = 0.870. Sequences of members of the Oryzomys macconnelli species complex are used as the outgroup. Bold numbers at internal nodes are bootstrap values, based on 1000 replicates percentages are mean Kimura twoparameter distances for all haplotypes below a given node. Haplotypes are identified by locality, as in the map, fig. 96, and provenance and voucher catalogue numbers are listed in table 34.
