The gradual closing of the Panama Isthmus is the only geographical
event that influenced Preponini dispersal. |

|
The gradual uplift of the Andes mountain range is the only
geographical event that influenced Preponini dispersal. The Andes uplift
generated a reconfiguration of the Amazonian lowland landscape by aiding
the formation of the Pebas system and subsequently the Acre system. |
