Deep genetic divergence in giant red shrimp Aristaeomorpha foliacea (Risso, 1827) across a wide distributional range

Multilocus Comparative Phylogeography of Two Aristeid Shrimps of High Commercial Interest (Aristeus antennatus and Aristaeomorpha foliacea) Reveals Different Responses to Past Environmental Changes

“…Sub-samples of 50 Aristeus antennatus and 40 Aristaeomorpha foliacea individuals were selected from previous works based on mtDNA [17], [18] according to two criteria: i) each putative biogeographical region had to be represented by 10 individuals, ii) previous levels of within locality mitochondrial genetic were maintained (Table S1 and Table S2). Biogeographical regions selected for Aristeus antennatus [17] were Alborán Sea (ALB), Western Mediterranean (WM), Eastern Mediterranean (EM), Atlantic Ocean (AO) and Mozambique Channel (MOZ) (Table 1); Gulf of Lion was selected as representative of WM and Ionian Sea as representative of EM.…”

“…Biogeographical regions selected for Aristeus antennatus [17] were Alborán Sea (ALB), Western Mediterranean (WM), Eastern Mediterranean (EM), Atlantic Ocean (AO) and Mozambique Channel (MOZ) (Table 1); Gulf of Lion was selected as representative of WM and Ionian Sea as representative of EM. It has been inferred that A. antennatus between the Ionian Sea and Aegean Sea are genetically similar based on the fact that A. foliacea were genetically similar between these two Seas [18]. The biogeographical regions selected for Aristaeomorpha foliacea [18] were WM, EM, MOZ and North-Western Australia (AUS); Cabrera was selected as representative of WM and Aegean Sea as representative of EM (Table 1).…”

“…From a population genetic perspective, a number of studies on Aristeus antennatus and Aristaeomorpha foliacea were consistent in showing a general picture of relative genetic homogeneity within the Mediterranean Sea [12]–[16]. Genetic analysis including samples beyond the Mediterranean basin detected moderate to high levels of genetic differentiation in both species [17], [18]. For example, mitochondrial DNA (mtDNA) analysis of Aristeus antennatus detected significant genetic differentiation among Western Mediterranean, Eastern Mediterranean, Atlantic Ocean and Mozambique Channel [17].…”

“…For example, mitochondrial DNA (mtDNA) analysis of Aristeus antennatus detected significant genetic differentiation among Western Mediterranean, Eastern Mediterranean, Atlantic Ocean and Mozambique Channel [17]. Similarly, analysis of Aristaeomorpha foliacea detected three mtDNA monophyletic lineages corresponding to Mediterranean Sea, Mozambique Channel and North-Western Australia [18].…”

“…Such studies should be based on diverse loci because different genes may be responding idiosyncratically to the evolutionary forces operating upon populations [20]. A major limitation of previous genetic studies on these two species [17], [18] is their reliance on mtDNA which only partially reflects their evolutionary history. In addition to one mitochondrial marker (cytochrome c oxidase subunit I, COI), we include nuclear molecular markers in this study: phosphoenolpyruvate carboxykinase (PEPCK) and sodium–potassium ATPase α -subunit (NaK).…”
