abstract = {With its 788 species in 67 genera in the Neotropics, the Arecaceae are an important ecological and economic component of the region. We review the influence of geological events such as the Pebas system, the Andean uplift, and the land connections between South and Central/North America, on the historical assembly of Neotropical palms. We present a case study of the palm genus Astrocaryum (40 spp.) as a model to evaluate colonization and diversification patterns of lowland Neotropical taxa. We conducted a Bayesian dated phylogenetic analysis based on four low-copy nuclear DNA regions, and a biogeographical analysis using the dispersal, extinction and cladogenesis model. Cladogenesis of Western Amazonian Astrocaryum species (ca. 6 Mya) post-dated the drainage of the aquatic Pebas system, supporting Pebas? constraining role on in situ diversification and colonization. The ancestral distribution of Astrocaryum species in the Guiana Shield supported the hypothesis of an old formation that acted as a source area from where species colonized adjacent regions, but a basal position for Guianan species was not confidently recovered. A two-fold increase in diversification rate was found on a clade whose ancestor occupied the Guiana Shield (ca. 13 Mya), and at a time of climatic change and Andean uplift.}
