    High-resolution genetic analysis reveals extensive gene flow within the jellyfish Pelagia noctiluca (Scyphozoa) in the North Atlantic and Mediterranean Sea

    Biological Journal of the Linnean Society.

    Despite the importance of gela tinous zooplankton as component s of marine ecosystems, both ecologically and socio-economically, relatively little is known about population persistence or connectivity in jellyfish. In the present study, we employed a combination of nuclear microsatellite markers and sequence data from the mitochondrial cytoch rome oxidase I (COI) gene to determine levels and patterns of population genetic st ructuring in the holoplanktonic jellyfish Pelagia noctiluca across the northeast Atlantic Ocea n and Mediterranean Sea. Our results indicate a high de gree of connectivity in P. noctiluca , with little evidence of geographical structuring of gene tic variation. A small but si gnificant differentiation of Atlantic Ocean and Mediterranean stocks was de tected based on the micr osatellite data, but no evidence of differentiation was observed with the mtDNA, probably due to the higher power of the microsatellites to detect low levels of genetic structuring. Two clearly distinct groups of genotypes were observed within the mtDNA COI, which probably diverged in the early Pleistocene, but with no evidence of geographical structuri ng. Palaeodistribution modelling of P. noctiluca at the Last Glacial Maximum (LGM; ca . 21 KYA) indicated large areas of suitable habitat south of the species’ current-day distribution, with little reduction in area. The congruent evidence for minimal genetic differentiation from the nuclear microsatellites and the mtDNA, coupled with th e results of the palaeodistribution modelling, supports the idea of long-term population stab ility and connectivity, thus providing key insights into the population dynamics and de mography of this important species.
