Plant recording across two centuries reveals dramatic changes in species diversity of a Mediterranean archipelago

Abstract Although islands are model systems for investigating assembly of biological communities, long-term changes in archipelago communities are not well understood because of the lack of reliable data. By using a vast amount of floristic data we assembled a dataset of the plant species occurring...
