We reconstructed archipelago configurationsat the following sea levels: the present‐day high interglacial sea level, the intermediatesea levels that are representative of the Pleistocene and the low sea levels ofthe LGM. We fitted two alternative linear mixed models for each archipelago configurationusing the number of single‐island endemic, multiple‐island endemic and (nonendemic)native species as a response. Model performance was assessed based onthe goodness‐of‐fit of the full model, the variance explained by archipelago configurationand model parsimony.Results: Single‐island endemic richness in both taxonomic groups was best explainedby intermediate palaeo‐configuration (positively by area change, and negatively bypalaeo‐connectedness), whereas non‐endemic native species richness was poorly explainedby palaeo‐configuration. Single‐island endemic richness was better explained by intermediate archipelago configurations than by the archipelago configurations ofthe LGM or present‐day PB Wiley SN 1466-822X YR 2018 FD 2018 LK http://riull.ull.es/xmlui/handle/915/16817 UL http://riull.ull.es/xmlui/handle/915/16817 LA en DS Repositorio institucional de la Universidad de La Laguna RD 07-oct-2024
