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´.

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.
