Introgression in Brownea: phylogenomic and population genomic data

Investigating hybridization among species of Amazonian trees in the genus Brownea, which was previously seen as a nearly non-existent phenomenon in Amazonian trees.As a member of the legume family, which dominates Amazonian forests, and with its apparent propensity for hybridization, Brownea is an excellent system with which to study the phylogenetic patterns and genomic architecture of introgression in neotropical rainforest trees. Systematically documenting hybridization at a range of time scales and taxonomic levels within this group could reveal how admixture has contributed to the assembly of one of the world’s richest floras. Accordingly, this investigation aims to answer the following questions:1. Is there evidence of hybridization at a deep phylogenetic level in this lineage of neotropical rainforest tree?2. Is there evidence of more recent gene flow, and if so, does this occur evenly across most of the genome?
