“…3. The smaller symbols ( pins ) indicate samples from literature data, from where M. edulis only was previously recorded on genetic grounds (Varvio et al 1988; McDonald et al 1991; Hummel et al 1999, 2001). “Sc” ( square symbol ) indicates published observations of M. trossulus from a Scottish loch, within the M. edulis/M.…”

“…In Europe, M. trossulus has been known from the Baltic Sea (Varvio et al 1988; McDonald and Koehn 1988; Väinölä and Hvilsom 1991; Riginos and Cunningham 2005), whereas M. edulis and M. galloprovincialis are the principal mussel taxa elsewhere in the North-East Atlantic area (Seed 1992; Hummel et al 2001). A steep intergradation zone in multiple allozyme characters between Baltic M. trossulus and North Sea M. edulis in the Öresund strait was described by Theisen (1978) and Väinölä and Hvilsom (1991).…”

“…It is notable in this context that while M. trossulus is regarded as a typically northern member of the Mytilus complex, several genetic studies have found M. edulis to be the exclusive Mytilus taxon in the very North of Europe (e.g., Varvio et al 1988; McDonald et al 1991; Hummel et al 1999, 2001; Smietanka et al 2004; Riginos and Henzler 2008; this includes all localities so far reported from Iceland and the Norwegian, Barents and the White seas). Yet there are previous notions of unexpected systematic heterogeneity of mussels in the Barents Sea sector from DNA-DNA hybridization data (Milyutina and Petrov 1989, 1997) and from shell characters also from the White Sea (Zolotarev and Shurova 1997).…”

Mytilus trossulus in Northern Europe

From data on allozyme, nuclear DNA and mitochondrial DNA markers, we show that the originally North Pacific/Northwest Atlantic mussel Mytilus trossulus is widespread on North European coasts, earliM. trossuluser thought to be inhabited only by Mytilus edulis. Several local occurrences of , interspersed with a dominant M. edulis, were recorded on the North Sea, Norwegian Sea and Barents Sea coasts of Norway and the Barents and White Sea coasts of Kola Peninsula in Russia. The proportion of M. trossulus genetic background observed at any one site varied from 0 to 95%. These new occurrences are not related to the previously known, introgressed M. trossulus population that occupies the Baltic Sea. The new northern occurrences retain both the F and M M. trossulus mitochondria, which have been lost from the Baltic stock. While hybridization takes place wherever M. trossulus and M. edulis meet, the extent of hybrization varies between the different contact areas. Hybrids are rare, and the hybrid zones are bimodal in the northern areas; more interbreeding has taken place further south in Norway, but even there genotypic disequilibria are higher than those in the steep transition zone between the Baltic mussel and M. edulis: there is no evidence of a collapse toward a hybrid swarm unlike in the Baltic. The Barents and White Sea M. trossulus are genetically slightly closer to the NW Atlantic than NE Pacific populations, while the Baltic mussel has unique features distinguishing it from the others. We postulate that the presence of M. trossulus in Northern Europe is a result of repeated independent inter- or transoceanic cryptic invasions of various ages, up to recent times.Electronic supplementary materialThe online version of this article (doi:10.1007/s00227-010-1609-z) contains supplementary material, which is available to authorized users.

“…To date, more than ten species of mussel have been identified, and the current systematic status of the bivalves along the European coast refers to three genetic groups of Mytilus edulis, namely the Atlantic mussel Mytilus edulis edulis, Mytilus edulis trossulus, and the Mediterranean mussel Mytilus edulis galloprovincialis (Hummel et al 2001). Although a number of studies have Table 1 Details of sampling campaigns (region, site, site code, date, depth, and location in the littoral zone, ambient temperature, and salinity) and collected mussels (taxonomic identification, mean size ± standard deviation, number of pools, and number of individuals in each pool (in brackets)) Region been undertaken in recent decades to clarify their distribution range, species identification of the genus Mytilus in some water basins in Europe still remains debatable.…”

“…This is primarily because of the broad ecological plasticity of mussels, which are able to adapt to different environmental conditions (Presa et al 2002). Additionally, intentional human activities such as commercial trade for aquaculture and consumption and unintentional activities such as shipping and the pollution of coastal areas have recently been shown to cause a northeastward shift in the distribution of mussels along the European coast (Hummel et al 2001). …”

Mussels from Mytilus edulis complex were used as biomonitors of the trace metals Fe, Mn, Pb, Zn, and Cu at 17 sampling sites to assess the relative bioavailability of metals in coastal waters around the European continent. Because accumulated metal concentrations in a given area can differ temporally, data were corrected for the effect of season before large-scale spatial comparisons were made. The highest concentration of Fe was noted in the North Sea and of Mn in the Baltic. Increased tissue concentrations of Pb were recorded in the mussels from the Bay of Biscay and the Baltic Sea. Low concentrations of metals were determined in the mussels from the Mediterranean Sea and the Northern Baltic. Relatively low geographic variations of Cu and Zn indicate that mussels are able to partially regulate accumulated body concentrations, which means Cu and Zn are, to some extent, independent of environmental concentrations.
