| Summary: | With the aim of explaining the role that taxa and island features have in biogeographical patterns, we processed presence-absence matrices of all the Macaronesian native species of ten different taxa (arthropods, birds, bryophytes, fungi, lichens, mammals, mollusks, pteridophytes, reptiles and spermatophytes) through simulated annealing analysis. Distribution patterns among the archipelagos were pinpointed, along with the different biogeographic roles played by islands and species groups. All the networks analysed resulted to be significantly modular and the structure of biogeographic modules reflects known past connections among the archipelagos and the current drivers of species distribution. The role assigned to the species supports some biological (ecological amplitude, degree of endemicity) and functional (long-distance dispersal and persistence abilities) traits of their respective biota and justifies their position in recent models of biogeographical distribution. Whereas it was expected that the ... : Annex1_MATRICES and Annex2_ROLESANNEX1 - Processed matrices of the considered Taxonomic Operational Unit (TOUs), corresponding to the presence/absence data from Macaronesia, available for the following organisms: arthropods, bryophytes, fungi, lichens, pteridophytes, spermatophytes, molluscs, reptiles, birds, mammals.
