Fig. 160 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 160. Phenogram of Jaccard's similarity coefficients in comparisons of species composition between all documented species of marsupials, murid rodents, and echimyid rodents from each of the 16 primary sample sites along the Rio Jurua´. Terminal branches are identified by locality number (see map, fig. 1); hatched boxes at basal nodes represent 95% confidence limits. Mantel's matrix correlation coefficient for the association between the similarity matrix and the cophenetic correlation matrix is 0.873, p <0.001.

Fig. 167 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 167. (A) A maximumlikelihood tree of 47 cytochromeb haplotypes of the terrestrial spiny rat, Proechimys simonsi, recovered from 150 individuals from 11 localities along the Rio Jurua´. (B) A maximumlikelihood tree of 48 cytochromeb haplotypes of the terrestrial spiny rat, Proechimys steerei, recovered from 205 individuals from 13 localities along the Rio Jurua´. The locality (or localities) and river bank (R = right, L = left) for each haplotype are indicated. The solid circles indicate cases where individual haplotypes had to be transferred across the river given these particular tree topologies; those in a terminal position represent single haplotypes presently found on both banks, those at internal nodes hypothesize historical transfers to account for the genealogical distribution.
Fig. 163 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 163. The relationship between average sequence divergence (Kimura twoparameter distances for the mitochondrial cytochromeb gene and the relative degree of phylogeographic partitioning in 30 species or species pairs of nonvolant mammals of the Rio Juruá (following Avise et al., 1987). A high degree of phylogeographic structure indicates that haplotype lineages are confined to particular sections along the river, either left versus right bank or some pattern of regional partitioning. Medium structure is when some haplotype lineages are confined to single geographic areas while others are not. Finally low or no structure characterizes those taxa where there is no relationship between haplotype lineages and geography. The four phylogeographic categories of Avise et al. (1987; Avise, 1989) are indicated with Roman numerals.

Mantel's matrix correlation coefficients and their significance are indicated for each.
Fig. 145 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 145. (Above) Map of the distribution of Proechimys echinothrix (modified from da Silva, 1998 illustrating localities for which 801 bp of cytochromeb sequence are available, lettered or numbered as in the tree (bottom). Localities belonging to each of the three mtDNA clades are encompassed by ellipses. (Below) Single most parsimonious tree generated by the branchandbound procedure for 18 individual haplotypes from the eight localities in the map (top). Length = 341 steps; CI = 0.757; RI = 0.872. Sequences of other species of Proechimys and of Mesomys were used to root the tree. Bold numbers at internal nodes are bootstrap values, based on 1000 replicates; percentages are average Kimura twoparameter distances. Voucher catalog numbers and localities for each haplotype are given in table 69.
Fig. 164. Three alternative phylogeographic hypotheses. A in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia
Fig. 164. Three alternative phylogeographic hypotheses. A: Primary Diversification: reciprocally monophyletic and sister clades bounded by a river that imposed itself on an existing species range. B: Secondary Contact: reciprocally monophyletic, but nonsister clades, bounded by a river that served as the secondary meeting point of clades that evolved elsewhere. C: Dispersal: paraphyletic relationship of right bank haplotypes relative to left bank ones due to one episode of crossriver transfer. See text for further explanation.
