Abstract
A partial sequence of mitochondrial cytochrome c oxidase subunit I (COI) was used as a genetic marker for a genetic diversity and phylogenetic analysis (DNA barcoding) of two Mactridae species, Mactra corallina and Eastonia rugosa, collected from the Tunisian coast. These Mactridae species could be distinguished by DNA barcoding techniques and they will be considered as monophyletic clades with the Neighbor-Joining (NJ) tree. The genetic structure detected that E. rugosa presents three haplotypes with a high frequency of HER1 (0.89). However, M. corralina shared 14 haplotypes. The haplotypic diversity (H) was equal to 0.205 and 0.954, respectively, for E. rugosa and M. corallina. While the nucleotide diversity (π) was higher for M. corallina (π=0.0818), the mismatch distribution showed a unimodal curve for E. rugosa (a recent sudden demographic expansion) and a multimodal distribution for M. corallina (size stability).
