Genetic diversity and biodiversity in the four case studies considered.

<p>For the analyzed samples: number of haplotypes; number of cytochrome oxydase I (COI) polypeptide variants; ratio between them (haplotypes/polypeptides); haplotypic diversity (Hd); nucleotide diversity (π).</p><p>For fish species representing 65% of the catch in each region: mean trophic level; ecological diversity index (Shannon); taxonomic index (Total Taxonomic Diversity); phylogenetic index (total sΦ⁺ value).
