Fig. 52 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 52. Strict consensus tree of 36 equallength maximum parsimony trees, based on 630 bp of the cytochromeb gene and illustrating topological relationships among cytochromeb haplotype clades of Micoureus. The tree is rooted by comparison to Metachirus, Marmosa, and Monodelphis (from Patton et al., 1996). Geographic provenance of haplotypes is indicated as in the map, fig. 51, and locality data are listed, from top to bottom, in table 12. Haplotypes for specimens from the Rio Juruá are identified by heavy lines and bold type. Bold numbers at internal nodes are bootstrap values, based on 1000 iterations; percentages are average Kimura twoparameter distances. Tree length = 450 steps; CI = 0.607; RI = 0.772.
Fig. 56 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 56. Bivariate relationship of four cranial dimensions for Micoureus demerarae and M. regina and condyloincisive length, a univariate measure of overall size. Correlation coefficients for each set of relationships are given. The respective slopes for the two species in each relationship are not significantly different, but their Yintercepts are (at p <0.01 or 0.001).
Fig. 49 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 49. Strict consensus tree of two minimumlength parsimony trees of the brown foureyed opossum, Metachirus nudicaudatus, based on the initial 450 bp of the mtDNA cytochromeb gene, and rooted by comparison to sequences from Didelphis and Philander. Branch lengths are proportional to the number of character changes. Regional reciprocally monophyletic clades are identified, and keyed to the localities mapped in fig. 48. Haplotypes for specimens from the Rio Juruá are identified by heavy lines and bold type; numbers refer to the specific locality as identified in the text and the map, fig. 1 Bold numbers at internal nodes are bootstrap values, based on 1000 iterations; percentages are average Kimura twoparameter distances. Individual haplotypes are identified by general locality, except for those from the Rio Jurua´, which are identified by specimen and locality numbers (see table 10). Tree length = 215 steps; CI = 0.730; RI = 0.842.
