Aim: In geographically and ecologically heterogeneous landscapes, such as tropical mountains, widely distributed species may be informative proxies for studying landscape and climatic evolution. We explore historical vicariant and dispersal processes that may have determined the genetic structure and variation of a palm species complex living in cloud forests. We hypothesize that the genomic groupings reflect uplift-based isolation by vicariance, divergence via dispersal events driven by faulted montane segments or recent divergence due to climate fluctuations. Location: Colombian Andes. Taxon: Geonoma undata–G. orbignyana species complex (Arecaceae). Methods: We sampled 195 individuals of the species complex plus the outgroup (G. inte...
