Molecular evidence for extensive discontinuity between peracarid (Crustacea) fauna of Macaronesian islands and nearby continental coasts: over fifty candidate endemic species
Oceanic islands are recognized evolutionary hotspots for terrestrial organisms, but little is known about their impact on marine organisms' evolution and biogeography. The volcanic archipelagos of Macaronesia occupy a vast and complex region in the Atlantic Ocean and may be particularly suitabl...

Oceanic islands are recognized evolutionary hotspots for terrestrial organisms, but little is known about their impact on marine organisms' evolution and biogeography. The volcanic archipelagos of Macaronesia occupy a vast and complex region in the Atlantic Ocean and may be particularly suitable to investigate marine island biogeography. In this study, we used mitochondrial DNA sequences (cytochrome c oxidase subunit I DNA barcoding region) to investigate the genetic differentiation between the populations from Webbnesia (i.e. Madeira, Selvagens and Canary Islands) and adjacent coasts (Azores, Continental Iberian Peninsula and Morocco) of 23 intertidal peracarid species. All species had high intraspecific genetic distances (>3%), reaching more than 20% in some cases. Between 79 and 95 Molecular Operational Taxonomic Units (MOTUs) were found in these species. Webbnesia populations displayed high genetic diversity and high endemicity, with 83% of the MOTUs being private to these islands, particularly La Palma and Madeira.
