Phylogenetic diversity indexes reported for each period: Faith’s index (PD), mean phylogenetic distance (MPD) and mean nearest taxon distance (MNTD). Estimators to complete angiosperm flora and differentiating native and exotic plants (only current time). Abbreviations after island names depict archipelago name: Juan Fernández archipelago (JFA) and Desventuradas archipelago (DA).
