Biogeography

Vargas, Oscar M [1], Dick, Christopher [2].

Biogeography and diversification of the Brazil Nut family, Lecythidaceae, in the Neotropics.

Lecythidaceae is an Amazon-centered family of trees whose species contribute disproportionately to stem abundance, alpha diversity, and biomass in South American rain forests. Fossil records indicate that Lecythidaceae diversification began in the Cretaceous and therefore spans the Cenozoic history of Andean uplift and Amazon basin development. We inferred a phylogeny of the family and addressed the following questions 1) What are the phylogenetic relationships within and among Lecythidaceae genera? 2) Are there major geographic centers of diversification (areas of clade endemism)?
