International audience Aim: Comparing genetic structure in species with shared spatial ranges and ecological niches can help identify how dissimilar aspects of biology can shape differences inpopulation connectivity. Similarly, where species are widely distributed across heterogeneous environments and major topographic barriers, knowledge of the structuringof populations can help reveal the impacts of factors which limit dispersal and/or drive divergence, aiding conservation management.Location: European seas of the northeast Atlantic and Mediterranean.Taxa: European clawed lobster (Homarus gammarus) and European crawfish (Palinurus elephas), two sympatric, heavily fished decapods with extensive dispersal potential.Methods: By RAD-sequencing 214 H. gammarus from 32 locations and 349 P. elephas from 15 locations, we isolated 6340 and 7681 SNP loci, respectively. Using these datato characterise contemporary population structuring, we investigate potential spatial and environmental drivers of genomic heterogeneity.Results: We found higher levels of differentiation among clawed lobsters than craw-fish, both globally and within basins, and demonstrate where known hydrographicand topographic barriers generate shared patterns of divergence, such as a genetic break between the Atlantic and Mediterranean basins. Genetic structure not commonto both species is principally apparent in the Atlantic portions of their range, where clawed lobster exhibits a genetic cline and increased differentiation towards rangemargins, while crawfish appear effectively panmictic throughout this region.Main Conclusions: We attribute the comparative lack of crawfish population structuring to their greater dispersal tendencies via a longer pelagic larval duration and spo-radic adult movements. In contrast, genetic connectivity in clawed lobster is relatively restricted, with the correlation of site of origin and temperature to geographical het-erogeneity at many divergent loci indicative of both neutral and adaptive processes.Our results help ... |
