Wild mussel populations of Mytilus galloprovincialis in a zone with marginal introgression of Mytilus edulis were affected at all levels, from high DNA damage to increased polycyclic aromatic hydrocarbon content in tissues. In this article, we describe cytological and population genetic changes of wild mussel populations from the northwestern Iberian coast following the catastrophe. The micronucleus test was employed as an indicator of cytological damage, and the Barcoding mitochondrial cytochrome oxidase I (COI) and the nuclear Glu-5′ genes were analyzed for determining the species and assessing population genetic diversity. Immediate increase of micronuclei counts after the oil spill was found, with a further decrease in consecutive months although the counts did not recover pre-Prestige levels. Reduced variation at mitochondrial sequences in the most exposed areas and reduction of M. edulis traces in the regional genetic pool also suggest long-term impact that may result in evolutionary changes. These results highlight the need of adopting more strict measures in order to prevent this type of accidents and avoid long-term effects on wild populations.</dcterms:abstract> <dc:creator>Garcia-Vazquez, Eva</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2015-02-22T07:14:54Z</dc:date> <dc:creator>Crego-Prieto, Victor</dc:creator> <dc:contributor>Prado, Andrea</dc:contributor> <dcterms:issued>2014</dcterms:issued> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/29944"/> <dc:contributor>Crego-Prieto, Victor</dc:contributor> <dc:contributor>Izquierdo, Jorge I.</dc:contributor> <dcterms:title>Cytological and Population Genetic Changes in Northwestern Iberian Mussels After the Prestige Oil Spill</dcterms:title> <dc:creator>Roca, Agustin</dc:creator> <dc:language>eng</dc:language> <dc:contributor>Roca, Agustin</dc:contributor> <dc:contributor>Arrojo-Fernández, José</dc:contributor> <dc:creator>Machado-Schiaffino, Gonzalo</dc:creator> <dc:creator>Prado, Andrea</dc:creator> <dc:contributor>Machado-Schiaffino, Gonzalo</dc:contributor> </rdf:Description> </rdf:RDF>
