Mapping of the positively selected sites in the three-dimensional model of the blue crab Callinectes sapidus COI protein from (A) native range and (B) invaded range. Sites identified by MEME are highlighted in purple; sites identified by the Codeml Branch-Site model A are highlighted in green. IMM = Inner mitochondrial membrane. IMS: intermembrane space. N, amino-terminal tail; C, carboxy-terminal tail. Codon positions 110 and 195, identified under positive selection by both MEME and branch-site model A in Codeml, are pointed at by black arrows. Green ellipses were placed around sites 110 and 195 from the invaded range to indicate that both methodologies found those positions to be under positive selection.
