This study provides the first high-quality reference genome for M. barbatus and a comprehensive set of SNP markers to investigate its population structure and adaptive potential across the Mediterranean. Using the newly generated chromosome-level reference genome, we re-analyzed a Mediterranean-wide reduced-representation genomic dataset. Our analysis reveals a panmictic population structure with strong genetic connectivity across the species' range, likely driven by extensive larval dispersal and multigenerational gene flow. Despite minimal genome-wide differentiation, outlier analysis identified candidate loci under directional selection, linked to key biological processes such as ontogeny and environmental adaptation. This study presents the first genomic resource for M. barbatus, providing valuable insights into its genetic structure and adaptive mechanisms. While the identification of loci under selection offers promising leads, these findings are preliminary due to the limited genomic coverage of the dataset. Nonetheless, they pave the way for future genomic studies to explore how M. barbatus adapts to environmental and anthropogenic pressures. These results hold significant implications for the sustainable management of Mediterranean fisheries, especially in the context of climate change and conservation. |
