“…2002 from a Scotian Shelf population (Blakeslee et al., 2010). Green crab population structure has been investigated previously using traditional genetic markers, including mitochondrial DNA (16S, Geller, Walton, Grosholz, & Ruiz, 1997; COI, Darling, Bagley, Roman, Tepolt, & Geller, 2008; Roman & Palumbi, 2004; Roman, 2006) and microsatellites (Darling, 2011; Darling et al., 2008, 2014; Pascoal et al., 2009; Tepolt, Bagley, Geller, & Blum 2006). In their native range, green crab show distinct broadscale structuring of island populations (i.e., Faeroe Islands and Iceland) and northern and southern European populations (Roman & Palumbi, 2004) using COI sequence data and fine‐scale (~450 km) structuring has been reported using microsatellite loci (Pascoal et al., 2009).…”
