The phylogeography of thornback rays (Raja clavata) was assessed from European waters, using five nuclear microsatellite loci and mitochondrial cytochome b sequences. Strong regional differentiation was found between the Mediterranean basin, the Azores and the European continental shelf. Allelic and haplotype diversities were high in Portuguese populations, consistent with the existence of a refugium along the Iberian Peninsula. Unexpectedly, high diversity was also found in the English Channel… 
Population structure and historical demography of the thorny skate (Amblyraja radiata, Rajidae) in the North Atlantic
TLDR
Historical demographic analysis showed that thorny skates have undergone exponential population expansion that started between 1.1 million and 690,000 years ago; and that the Last Glacial Maximum apparently had little effect.
Strong population genetic structure and contrasting demographic histories for the small-spotted catshark (Scyliorhinus canicula) in the Mediterranean Sea
TLDR
The current findings suggest that the small-spotted catshark exhibits several genetic stocks in the Mediterranean, although further study is needed.
Macaronesian islands as promoters of diversification in amphipods: The remarkable case of the family Hyalidae (Crustacea, Amphipoda)
TLDR
Investigation of the genetic structure and diversity of seven hyalid species inhabiting the Macaronesian, European and Moroccan Atlantic coasts, with a focus on the genetic differentiation between island and Continental populations indicates distinct evolutionary and diversification patterns among Hyalidae species.
Evidence of high genetic connectivity for the longnose spurdog Squalus blainville in the Mediterranean Sea
TLDR
These findings could be considered in species-specific conservation plans, although sampling over a larger spatial scale and more genetic markers are required to fully elucidate the genetic structure and dispersal potential of S. blainville.
Molecular phylogeny and biogeographic history of the European Maja spider crabs (Decapoda, Majidae).
Patterns of genetic variation across the distribution range of the cockle Cerastoderma edule inferred from microsatellites and mitochondrial DNA
TLDR
Both marine currents and historical processes, such as a recent population expansion of the southern group, the existence of northern cryptic refugia during Pleistocene glaciations and secondary contact between the southern and northern groups of populations, may explain the genetic composition of C. edule populations.
Phylogeography of an estuarine mysid, Neomysis integer (Crustacea, Mysida), along the north‐east Atlantic coasts
TLDR
Phylogeographical analysis revealed that northern populations within the English Channel, North Sea and Baltic Sea are characterized by several widespread haplotypes, while the Irish population and all sites south of the Bay of Biscay consist solely of unique haplotypes.
Unexpected High Genetic Diversity at the Extreme Northern Geographic Limit of Taurulus bubalis (Euphrasen, 1786)
TLDR
This work analysed the phylogeographic patterns of this species using mitochondrial and nuclear markers in populations throughout most of its distributional range in west Europe and found that T. bubalis has a relatively shallow genealogy with some differentiation between Atlantic and North Sea.

Population genetics of dwarf eelgrass Zostera noltii throughout its biogeographic range
TLDR
Although genetic diversity and allelic richness generally decreased from Mauri- tania to Denmark, the putative post-glacial recolonization route, both were unexpectedly high among populations from the German Wadden Sea.
Phylogeography of the common goby, Pomatoschistus microps, with particular emphasis on the colonization of the Mediterranean and the North Sea
TLDR
Gene flow analysis suggested that recolonization of the North Sea and the coasts of western Scotland and Ireland may have taken place from a glacial refugium in the Southern Bight of theNorth Sea.
Genetic structure of the flounders Platichthys flesus and P. stellatus at different geographic scales
TLDR
The genetic structure of the flounders Platichthys flesus L. and P. stellatus Pallas was investigated through analysis of allozyme variation at 7 to 24 polymorphic loci and the hypothesis of a two-step colonisation of the western Mediterranean was supported.
Genetic differentiation in a pelagic crustacean (Meganyctiphanes norvegica: Euphausiacea) from the North East Atlantic and the Mediterranean Sea
TLDR
The present work indicates that M. norvegica, although endowed with a high dispersal capacity because of its pelagic habit, can develop separate breeding units inside the same oceanic basin (the Atlantic).
Rapid Miocene–Pliocene dispersal and evolution of Mediterranean rajid fauna as inferred by mitochondrial gene variation
TLDR
The evolutionary history and dispersal of North‐east Atlantic and Mediterranean rajid fauna were investigated throughout the sequence analysis of the control region and 16S rDNA mitochondrial genes, and phylogenetic relationships indicated Mediterranean endemic skates derived from sister species with wider distribution during Late Pliocene–Pleistocene.
Disjunct distribution of highly diverged mitochondrial lineage clade and population subdivision in a marine bivalve with pelagic larval dispersal
TLDR
According to mitochondrial DNA sequence data, populations of this species can remain highly subdivided in spite of the potential for high gene flow, implying that their population and evolutionary dynamics can be independent.
Post‐ice age recolonization and differentiation of Fucus serratus L. (Phaeophyceae; Fucaceae) populations in Northern Europe
TLDR
The seaweed Fucus serratus is hypothesized to have evolved in the North Atlantic and present populations are thought to reflect recolonization from a southern refugium since the last glacial maximum, whereas the Spanish populations most likely reflect present‐day edge populations that have undergone repeated bottlenecks as a consequence of thermally induced cycles of recolonized and extinction.
North Atlantic phylogeography and large‐scale population differentiation of the seagrass Zostera marina L.
TLDR
The identification of a high genetic diversity hotspot in Northern Europe provides a basis for restoration decisions and links between historical and contemporary processes are discussed in terms of the projected effects of climate change on coastal marine plants.
Population structure of plaice (Pleuronectes platessa L.) in northern Europe: microsatellites revealed large‐scale spatial and temporal homogeneity
TLDR
The presence of significant heterozygote deficiencies at all locations (not due to null alleles) suggests a temporal Wahlund effect yet the absence of significant population differentiation among continental shelf localities makes this explanation alone, difficult to reconcile.
