“…Our results confirm previous studies of P. maximus documenting the presence of a Norwegian and an Atlantic group 12,13 . Uncovering the same pattern with a much larger panel of SNPs implies that genetic differences are distributed across the genome, which is consistent with our historical demographic analysis suggesting that the two lineages may have arisen independently from separate glacial refugia (see below).…”

“…Several studies have used genetic analysis to investigate the population structure of P. maximus in European coastal waters. Studies based on allozymes and mitochondrial DNA did not identify any genetic differences between French and British populations 9–11 but significant mitochondrial haplotype frequency differences were found between the UK and Norway 12 . These patterns were subsequently confirmed by Morvezen et al .…”

Recent developments in genomics are advancing our understanding of the processes shaping population structure in wild organisms. In particular, reduced representation sequencing has facilitated the generation of dense genetic marker datasets that provide greater power for resolving population structure, investigating the role of selection and reconstructing demographic histories. We therefore used RAD sequencing to study the great scallop Pecten maximus and its sister species P. jacobeus along a latitudinal cline in Europe. Analysis of 219 samples genotyped at 82,439 single nucleotide polymorphisms clearly resolved an Atlantic and a Norwegian group within P. maximus as well as P. jacobeus , in support of previous studies. Fine-scale structure was also detected, including pronounced differences involving Mulroy Bay in Ireland, where scallops are commercially cultured. Furthermore, we identified a suite of 279 environmentally associated loci that resolved a contrasting phylogenetic pattern to the remaining neutral loci, consistent with ecologically mediated divergence. Finally, demographic inference provided support for the two P. maximus groups having diverged during the last glacial maximum and subsequently expanded, whereas P. jacobeus diverged around 95,000 generations ago and experienced less pronounced expansion. Our results provide an integrative perspective on the factors shaping genome-wide differentiation in a commercially important marine invertebrate.

“…1993); however, this result may have been a consequence of poor marker resolution. More recently, variation at mitochondrial DNA (mtDNA) has been used to uncover significant genetic differences between British and Norwegian stocks of P. maximus (Ridgway & Dahle 2000) and among certain scallop populations from western Britain (Heipel et al . 1999).…”

We isolated and characterized nine polymorphic microsatellite loci from the great scallop (Pecten maximus) as part of an attempt to better understand the population–genetic structure of this species. Levels of genetic diversity were assessed in 32 scallops collected from the coastal waters of Port Erin Bay, Isle of Man. The number of alleles ranged from two to 29 and observed and expected heterozygosities varied between 0.031 to 0.906 and 0.062 to 0.973, respectively. Two loci showed significant (P < 0.05) heterozygote deficits, likely because of null (nonamplifying) alleles; one pair of loci was in linkage disequilibrium.

Florida Gulf bay scallops form a complex, mixed-model metapopulation (Harrison & Taylor 1997)-a combination between a pure source-sink metapopulation, in which all gene flow is from a donor source population to recipient sink populations (Tero et al 2003), and a classic metapopulation, in which all populations have roughly equivalent potentials to contribute recruits to all other populations (Levins 1970).…”
