Here we explore the mitogenomic variability of two endemic, ecologically important Mediterranean Paramuricea species. We assess their phylogenetic relationships and provide first insights into their evolution and biogeography. Complete mitogenome sequences of Paramuricea clavata and Paramuricea macrospina were obtained using long range PCR, primer-walking and Sanger sequencing. For an enlarge sample of Paramuricea species, maximum likelihood and Bayesian phylogenetic trees of the mitochondrial gene mtMutS were obtained and used to study the biogeographic history of Paramuricea through a statistical Dispersal-Vicariance method (S-DIVA). Divergence time was estimated under a strict molecular clock model in BEAST using published octocoral mutation rates. Our results revealed high nucleotide diversity (2.6%) among the two Mediterranean endemics; the highest mutation rates were found in the mtMutS, Nad4 and Nad5. In addition, we found length polymorphisms in several intergenic regions and diversity in mitochondrial genome size. The red gorgonian Paramuricea clavata was closely related to the Eastern Atlantic P. grayi rather than its Mediterranean congener, P. macrospina. Our biogeographic results provide evidence for the independent speciation of the Mediterranean species and point to a Miocene origin of the two endemics, highlighting the role played by the Messinian Salinity Crisis in the evolutionary history of Mediterranean Paramuricea. eng Poliseno Angelo Altuna Alvaro Cerrano Carlo Wörheide Gert Vargas Sergio 2016-04-28 570 590 10.5282/ubm/data.89 https://doi.org/10.5282/ubm/data.89 public endemic species Mediterranean mitogenomics Paramuricea phylogeography vicariance en none Vargas Sergio Poliseno Angelo fak20
