Abstract
We investigated genetic transitions in European anchovies Engraulidae by analysing one mitochondrial and six nuclear microsatellite loci in samples from 28 geographical locations primarily in the Western Mediterranean with external samples from the Black Sea in the East and the Gulf of Biscay in the West Four samples were collected from lagoons or shallow waters in France Morocco and Tunisia Two strongly differentiated loci and nucleocytoplasmic disequilibrium allowed us unambiguously to confirm the existence of a coastal genetic entity that is distinct from the more offshore marine populations By contrast four microsatellites were undifferentiated within the entire set of samples testifying to a variable permeability of the two interacting genomes Our findings strengthen and extend previous reports of the existence of a coastal anchovy entity that is widespread in Mediterranean lagoonsThe authors wish to thank Emeline Lambert for having initiated the mtDNA sequencing Jacques Dietrich for providing the Gulf of Lion’s samples and for unpublished data Daniela Banaru for Black Sea sample PierreAlexandre Gagnaire and Nicolas Bierne for helpful discussion Othman Jarboui for his support for the project and David McKenzie for linguistic revision The analytical part of this work was financed by basic institutional funding to François Bonhomme and was performed entirely at the Station Méditerranéenne de l’Environement Littoral in Sète During her stay in Sète Soumaya Oueslati was supported by French Embassy Tunisia and Program HubertCurien 27961XE fellowships
