Jaime Morin Lagos: Evolutionary history of Arini parrots (Psittacidae) elucidated by museum collections and pre-Hispanic featherworks from Peru


The tribe Arini is composed of approximately 86 species of neotropical parrots distributed in 20 genera. Previous molecular phylogenies of this tribe were inferred using a limited number of species and using a limited set of nuclear and mitochondrial markers, therefore resulting in unclear or contradictory evolutionary relationships. On my PhD project, I will tackle the systematics of the tribe Arini (Psittacidae) as a whole, with an emphasis in the speciose genus Pyrrhura. The generation of a large genomic dataset should provide enough resolution to resolve the relationship between species and current systematic problems within some complexes of species (e.g. melanura complex). Then, I will sequence multiple individuals of Ara parrots, with emphasis in Peruvian native populations. Using these individuals as a baseline, I will then sequence samples from archeological museums, historical avian collections, and parrots rescued from illegal trade. By using population genomics tools, I will be able to detect the geographic origins of historical individuals and illegal trade. This project will provide valuable information that can be employed in their conservation, and it will allow us to better understand the historical interactions between parrots and humans in the Neotropics.
