FIGURE 7 in Complicated histories: three new species of poison frogs of the genus Ameerega (Anura: Dendrobatidae) from north-central Peru

FIGURE 7. The biogeography of the bassleri clade is likely the result of multiple disturbance-vicariance events that resulted in periodic connections between the Cordillera Oriental and the Serranía de Contamana, followed by longer periods of isolation. This scenario assumes three periods of connectivity between the Cordillera Oriental and Contamana and would provide a mechanism for allopatric speciation in this group. Each species' distribution (and their ancestors) is depicted by the corresponding color. The bicolored pattern depicts the sympatry of two species.
