Microsatellite loci indicate population structure and selection between Atlantic and Gulf of Mexico populations of the bay scallop Argopecten irradians 

Genetic Population Structure in the Antarctic Benthos: Insights from the Widespread Amphipod, Orchomenella franklini

“…We detected directional selection acting between Casey and Davis populations of O. franklini at locus Orcfra4 , providing further evidence that these two regions are isolated and evolving independently. Although microsatellites are considered a neutral marker, they have increasingly been shown to reflect selection by genetic hitch-hiking [93] , [112] , [113] . Rather than rendering them uninformative, this provides valuable, biologically-relevant information on population structure [114] , [115] .…”

“…F ST varied considerably among loci (see results), so we tested for evidence of selection at each of the seven loci using Lositan [92] . Confidence intervals (99%) for neutral loci were determined using 20,000 simulations and the recommended ‘neutral mean F ST ’ option [93] .…”

Natural and Anthropogenic Forces Shape the Population Genetics and Recent Evolutionary History of Eastern United States Bay Scallops (Argopecten irradians)

“…In another analysis of RFLP variation in 2 mtDNA gene fragments (Bologna et al 2001), nucleotide divergences between NC and Florida Gulf samples were nearly 3-10 times greater than those between NC and other Atlantic samples. Only very recently, Hemond and Wilbur (2011) recognized NC bay scallops as A. i. irradians, based on allele frequency differences at several microsatellite DNA (msDNA) loci.…”

“…Some, but not all, of the samples analyzed in this study were included in Hemond and Wilbur's (2011) msDNA study. It would be interesting to match their NC msDNA genotypes with our genotype/haplotype combinations to investigate further the context of A. i. concentricus genes in the NC population.…”

Florida Gulf Bay Scallop (Argopecten Irradians Concentricus) Population Genetic Structure: Form, Variation, and Influential Factors

“…Florida Gulf bay scallops (Blake & Graves 1995, Wilbur 1995, Marelli et al 1997a, Marelli et al 1997b, Bologna et al 2001, Hemond & Wilbur 2011, including a genetic assessment of stock enhancement success (Wilbur et al 2005). Based on comparisons of the relatively genetically distant Atlantic bay scallop (Argopecten irradians ssp.…”
