Shared and distinct patterns of genetic structure in two sympatric large decapods

Aim: Comparing genetic structure in species with shared spatial ranges and ecological niches can help identify how dissimilar aspects of biology can shape differences in population connectivity. Similarly, where species are widely distributed across heterogeneous environments and major topographic barriers, knowledge of the structuring of populations can help reveal the impacts of factors that 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 6,340 and 7,681 SNP loci, respectively. Using these data to characterise contemporary population structuring, we investigate potential spatial and environmental drivers of genomic het..., RADseq derived SNP data obtained from rangewide samples of two lobster species, European lobster (Homarus gammarus) and European spiny lobster (Palinurus elephas), and R scripts for the subsequent analytical pipeline used to address questions of population genetic diversity, structure, selection and adaptation., R and numerous R packages (all open-source)., # Shared and distinct patterns of genetic structure in two sympatric large decapods
