Sažetak
The red gorgonian Paramuricea clavata is a long-lived and slow growing cnidarian. It is characterized by a fragmented distribution throughout the western Mediterranean, the Adriatic and the Aegean Sea including the neighbouring Atlantic Ocean. This species contributes significantly to the biomass and structural complexity of coralligenous assemblages. Over the last decade, P. clavata received particular attention due to ongoing threats that jeopardize its persistence, such as habitat destruction, invasive species, mucilaginous algal aggregates and global warming. In the western Mediterranean Sea, a global picture of the population genetic structure and diversity of the species is available. However, data is still deficient in the eastern Mediterranean region. To address this gap, we have studied for the first time the conservation genetics of P. clavata in the eastern Adriatic Sea. In particular, we assess genetic diversity, population genetic structure, patterns of gene flow and levels of connectivity among populations based on a hierarchical sampling scheme (13 populations belonging to 4 regions) and using seven microsatellites. Overall, our results are concordant with previous studies on P. clavata showing a significant pairwise genetic differentiation at the local scale in combination with isolation by distance and regional genetic clustering at the global scale. Nevertheless, we demonstrate the occurrence of four regional clusters and high and specific genetic diversity when compared to previously studied regions. Moreover, this study is among the first to furnish data on low dispersive species in the eastern Adriatic Sea, thus providing new perspectives for the creation and improvement of management plans for P. clavata and associated coralligenous communities in this part of the Mediterranean.
