Fig. 168 in Mammals Of The Rio Juruá And The Evolutionary And Ecological Diversification Of Amazonia

Fig. 168. Generalized gene genealogies of Neacomys minutus and Mesomys hispidus, two phylogeographic category I species of the Rio Juruá illustrating common patterns in their respective distributions of reciprocally monophyletic cytochrome­b clades. In both cases, as well as in nine other species or species­pairs, monophyletic clades are split into upriver (Headwaters and Upper Central regions) and downriver (Lower Central and Mouth regions), although overlap may be present in either the Upper or Lower Central regions, as is true for M. hispidus.
