Description
The culturally and economically significant Andean tree genus Polylepis—which forms the world’s highest-elevation treelines—has long eluded a well-supported phylogenetic reconstruction, possibly due to extensive gene flow, hybridization, and polyploidization. To address this, we investigate sympatric populations of P. neglecta (Bolivia) and P. incana (Ecuador) using genomic (ddRADseq) and morphological data. Our goal is to provide empirical evidence for these evolutionary processes and to propose strategies for reconstructing the phylogeny of the genus. We hypothesize that, despite high levels of gene flow and hybridization, species boundaries remain distinct, and that ddRADseq data will provide high phylogenetic resolution.
