“…Globally, both markers analysed revealed high genetic diversity in D. trunculus in line with previous studies based on microsatellites (Marie et al, ; Nantón et al, ). Based on the 16S gene, the F type revealed abundant haplotype diversity (0.679) and low levels of nucleotide diversity (0.0046).…”

“…However, pairwise F ST using the M combined sequences displayed three groups: the Mediterranean group (GA, DE, MA), the Atlantic group (all localities on the coast of the Atlantic Ocean), and the Alboran group (FU). The population structure proposed in this study (three groups: Atlantic, Mediterranean, and Alboran) was observed previously using microsatellite markers (Marie et al, ; Nantón et al, ). The existence of two independently evolving mitochondrial lineages should be considered when population structure studies are carried out in species with DUI.…”

“…The genetic structure detected for D. trunculus in the Iberian Peninsula could be related to the existence of geographical barriers in this region, and the Almeria–Oran front and the Strait of Gibraltar could be the reason for this geographical confinement. The Almeria–Oran front constitutes an oceanographic discontinuity that not only has shown a significant effect on the genetic structure of this wedge clam (Marie et al, ; Nantón et al, ), but also on different species of bivalves, such as the mussels M. edulis and M. galloprovincialis (Diz & Presa, ; Luis, Comesaña, & Sanjuan, ; Quesada, Beynon, & Skibinski, ; Sanjuan, Comesaña, & De Carlos, ; Sanjuan, Zapata, & Álvarez, ; Sanjuan, Zapata, & Álvarez, ) and in the scallops Pecten jacobaeus and Pecten maximus (Ríos, Sanz, Saavedra, & Pena, ), or in other marine organisms such as Dicentrarchus labrax (Naciri, Lemaire, Borsa, & Bonhomme, ), Meganyctiphanes norvegica (Zane et al, ), Serranus cabrilla (Schunter et al, ), or Liocarcinus depurator (García‐Merchán et al, ). The Alboran Sea, located west of the Mediterranean Sea, borders the Atlantic Ocean along the Strait of Gibraltar.…”

“…To date, population genetic analyses based on microsatellite markers have provided evidence that, in the Iberian Peninsula, D. trunculus displays a genetic differentiation along the Atlantic–Mediterranean transition with three distinct groups: the Atlantic Ocean, the Alboran Sea, and the Mediterranean Sea (Marie et al, ; Nantón et al, ; Rico et al, ). However, the use of different marker types has shown discrepancies in diversity patterns in other species (Brito, ; Ferchaud et al, ; Hoffman et al, ; Johnson, Toepfer, & Dunn, ; Martínez, Freire, Arias‐Pérez, Méndez, & Insua, ; Toews & Brelsford, ).…”

“…The objectives of the study were to characterize the genetic diversity within localities and to verify the population structure and demographic patterns previously inferred based on nuclear markers (Marie et al, ; Nantón et al, ). The results can aid in the design of fishery management and conservation strategies for D. trunculus inhabiting the Atlantic and Mediterranean coasts, and the recovery of the natural beds in the north‐western Atlantic area.…”

1. The wedge clam, Donax trunculus (Linnaeus, 1758), is an ecologically and economically important species found in the warm waters of the Atlantic and Mediterranean areas. Donax trunculus has been suffering from a severe population decline in some wild stocks of the Iberian Peninsula, and genetic monitoring of wild populations can provide valuable information to support conservation measures and management policies.2. In this study, mitochondrial 16S rDNA (16S) and cytochrome b (Cytb) gene variation was examined at 18 localities across the Iberian Peninsula to test whether the patterns of genetic diversity, population structure, and demographic inferences previously deduced by using microsatellites are supported by these molecular markers. 3. Samples (N = 557) were collected from 18 localities of the Iberian Peninsula and attention was paid to the north-western Atlantic area, where wild stocks have diminished greatly. Analysis of molecular variance, fixation index ( F ST ), and demographic inferences were estimated based on mitochondrial DNA. Since D. trunculus shows doubly uniparental inheritance, both types of mitochondrial DNA (F and M) were analysed. 4. A high level of genetic diversity was detected using the haplotype diversity dataset, showing different geographic patterns. 5. F ST values for the M type revealed significant differentiation between populations on both sides of the Almeria-Oran front, and between the locality from the Alboran Sea (FU) and localities from the Atlantic Ocean. However, the F type did not detect the differentiation of FU. This makes the M genome sequences more suitable for investigating genetic structure of D. trunculus populations. 6. Management and recovering strategies of this important resource should consider the genetic structure observed. 7. Several strategies for conservation and management of this commercial and ecologically important bivalve are proposed. * Both authors contributed equally to this work.

Isolation of microsatellite loci for the endangered vermetid gastropod Dendropoma lebeche using Illumina MiSeq next generation sequencing technology

Dendropoma petraeum, considered the primary vermetid reef-building species in the Mediterranean, has recently been shown to be a species complex of at least four cryptic species. These species have highly restricted, non-overlapping distributions, causing concern for their conservation status. To better study the genetic diversity of these populations, we selected one of these species, Dendropoma lebeche (Templado et al. in Mediterr Mar Sci 17(1):13-31, 2016), which is restricted to the western Mediterranean, for microsatellite marker development using Illumina MiSeq. We provide an initial survey of 29 polymorphic microsatellite loci for D. lebeche. Genetic analyses identified 2-11 alleles per locus across the 30 samples examined. Observed and expected heterozygosities ranged from 0.067 to 0.800 and 0.064 to 0.770, respectively. None of the loci deviated from Hardy-Weinberg equilibrium or showed signs of being under selective pressure. Significant linkage disequilibrium was found between two loci. We also show the cross-species amplification of these microsatellite markers in the other three species of the complex, the Tyrrhenian-Sicilian lineage, D. cristatum (Biondi, 1859), the Levantine lineage, D. anguliferum (Monterosato, 1878) and Dendropoma sp. found along the Ionian-Aegean coasts, suggesting their potential utility for future phylogenetic and evolutionary studies.
