“…The values obtained in our study are slightly lower than the ones found for other bivalves, such as in mussel (Mytilus galloprovincialis) populations in Southern California (Li Ma et al 2000) or in European populations of the razor clam Ensis siliqua (Fernández-Tajes et al 2007), but are similar to the one's obtained in another veneroid species (R. decussatus) populations in Algarve coast (Southern Portugal;Pereira 2008). Shannon's diversity index is well suited to the analysis of RAPD data as it is relatively insensitive to the bias produced by failures to detect heterozygous individuals (Dawson et al 1995).…”

“…On the other hand, the genetic variability observed for the RAPD markers within samples was higher than that obtained from other marine species (e.g. De Wolf et al 1998;Ma et al 2000;Aranishi and Okimoto 2004). The level of variability observed for each sample was generally correlated in both types of markers.…”

The sword razor shell Ensis siliqua (Linnaeus, 1758) is a bivalve with a high commercial value being appreciated in fresh and processed markets. However, the genetic studies carried out in populations of E. siliqua are scarce. In this work, the genetic variability and diVerentiation of the sword razor shell was assessed using PCRRFLPs of a fragment of the 16S rRNA mitochondrial gene and random ampliWed polymorphic loci (RAPD) in nine localities from Ireland, Spain, and Portugal. In the 314 individuals examined for the mitochondrial fragment, 12 composite haplotypes were observed; meanwhile, a unique phenotype was observed for each of the 242 individuals analyzed with 61 RAPD loci. Two of the mitochondrial composite haplotypes accounted for the majority of individuals (89.81%) and showed a remarkably disjoint distribution between Irish and Iberian samples, with the exception of Aveiro which exhibited as the most frequent haplotype the same found in Ireland. The level of variability observed for each sample was generally correlated with both types of markers and the results obtained suggest the existence of a strong population diVerentiation between Irish and Iberian localities, except for the Portuguese sample from Aveiro which is surprisingly closer to Irish individuals, although it is probably highly diVerentiated.

“…Evolution of increased tolerance to contaminants is also demonstrated in natural populations of coastal waters (Wirgin and Waldman 2004;Eriksson et al 2009). Moreover, populations of marine organisms sometimes show lower genetic variation at contaminated sites compared to control sites (Ma et al 2000;Bickham et al 2000).…”

Environmental change challenges local and global survival of populations and species. In a speciespoor environment like the Baltic Sea this is particularly critical as major ecosystem functions may be upheld by single species. A complex interplay between demographic and genetic characteristics of species and populations determines risks of local extinction, chances of re-establishment of lost populations, and tolerance to environmental changes by evolution of new adaptations. Recent studies show that Baltic populations of dominant marine species are locally adapted, have lost genetic variation and are relatively isolated. In addition, some have evolved unusually high degrees of clonality and others are representatives of endemic (unique) evolutionary lineages. We here suggest that a consequence of local adaptation, isolation and genetic endemism is an increased risk of failure in restoring extinct Baltic populations. Additionally, restricted availability of genetic variation owing to lost variation and isolation may negatively impact the potential for evolutionary rescue following environmental change.
