Status of Mytillus galloprovinciallis Lamarck, 1819 in the southeastern Adriatic confirmed by genetic markers

Mytilus spp. are considered key species of the coastal ecosystem in the Adriatic sea and are commercially valuable. Genetic characterization of their populations may serve to monitor changes in diversity, and possibly for understanding the biodiversity changes in the coastal ecosystems in the Adriatic sea. During 2005 and 2006, as part of comprehensive project concerning Mytilus species complex in the Mediterranean and parts of the eastern Adriatic from Boka Kotorska bay to Limski channel.We sampled 262 individuals from 10 locations. Following DNA extraction (Quiagen, Dneasy Tissue kit), and PCR amplification using genetic markers, electrophoresis revealed one single and uniform band for all of investigated individuals on the postion characteristic for M. galloprovincialis .For the final verification we obtained the standard confirmed total DNA of M. galloprovincialis, M. edulis and M. trossulus and upon comparison of these on electrophoresis – all of our individuals equaled the band position as that of standard M. galloprovincialis. We suggest that M. galloprovincialis is an invasive species by its nature (1) and that trait may be the reason for preserving its purity.
