AB Aim: To quantify the influence of past archipelago configuration on present‐day insularbiodiversity patterns, and to compare the role of long‐lasting archipelago configurationsover the Pleistocene to configurations of short duration such as at the LastGlacial Maximum (LGM) and the present-day.Location: 53 volcanic oceanic islands from 12 archipelagos worldwide—Azores,Canary Islands, Cook Islands, Galápagos, Gulf of Guinea, Hawaii, Madeira, Mascarenes,Pitcairn, Revillagigedo, Samoan Islands and Tristan da Cunha.Time period: The last 800 kyr, representing the nine most recent glacial–interglacialcycles.Major taxa studied: Land snails and angiosperms.Methods: Species richness data for land snails and angiosperms were compiled fromexisting literature and species checklists. 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
