Genetic structure among P. juliflora individuals from Kenya and Ethiopia based on STRUCTURE and Principal component analyses A STRUCTURE bar plots for P. juliflora individuals from plantations (Plant), sites neighbouring plantations (Neigh) and far-off invaded (Inv) from the Afar Region in Ethiopia (AF), Baringo County (BA) and Taveta (TA) in Kenya (see text for further details). Vertical line plots represent the assignment (qik values) of individual genomes to the two inferred genetic clusters B principal component analysis (PCA) showing the assignment of individuals to the inferred STRUCTURE genetic clusters. PCA was performed using Bruvo distances calculated using PolySat (Bruvo et al. 2004).
