Introgression patterns in the mosaic hybrid zone between Mytilus edulis and M. galloprovincialis
TLDR
The genetic structure of the mosaic hybrid zone between the marine mussels Mytilus edulis and M. galloprovincialis is analysed using three length‐polymorphic PCR loci as neutral and diagnostic markers along the Atlantic coast of Europe, indicating a strong genetic barrier within all transition zones.
The zone of sympatry and hybridization of Mytilus edulis and M. galloprovincialis, as described by intron length polymorphism at locus mac-1
TLDR
It is proposed that the distinctness of the Atlantic M. galloprovincialis population results from past introgression by M. edulis, and these results were consistent with published allozyme data, suggesting that they can be extended to the entire nuclear genome.

TLDR
It is argued in this study that Australasian mussels derive from a proto- M. galloprovincialis population introgressed by M. edulis-like genes, and should be considered as a regional subspecies of M.galloprov provincialis.
Direct selection on allozymes is not required to explain heterogeneity among marker loci across a Mytilus hybrid zone
TLDR
The levels of genetic differentiation varied widely among both allozymes and noncoding DNA markers and no clear difference emerged between the two types of markers, suggesting that the strong interlocus variance in genetic differentiation has been confounded with a discrepancy between marker types as a result of an insufficient and unbalanced locus sampling.
Genetic entities and mating system in hermaphroditic Fucus spiralis and its close dioecious relative F. vesiculosus (Fucaceae, Phaeophyceae)
TLDR
It is argued that interspecific gene flow has occurred after divergence of the two taxa, and it is shown that whether recently separated or recently introgressive, the divergent breeding systems probably contribute to species integrity in these twoTaxa.
Genomic reticulation indicates mixed ancestry in Southern-Hemisphere Mytilus spp. mussels: MIXED ANCESTRY IN SOUTHERN-HEMISPHERE MYTILUS
TLDR
Genetic drift superimposed on ancient hybridization and introgression may explain the genomic reticulation observed in both Kerguelen and Tasmanian mussels.
GENETIC ISOLATION BETWEEN THREE CLOSELY RELATED TAXA: FUCUS VESICULOSUS, F. SPIRALIS, AND F. CERANOIDES (PHAOPHYCEAE) 1
TLDR
Whether the different populations of the Fucus vesiculosus, F. spiralis, and F. ceranoides were grouped according to their geographical location, their habitat, or their a priori taxonomic assignment is assessed.
Implications of mating system for genetic diversity of sister algal species: Fucus spiralis and Fucus vesiculosus (Heterokontophyta, Phaeophyceae)
TLDR
Results revealed that selfing is characteristic in F. spiralis across its latitudinal distribution along the Iberian and French Atlantic coasts, and higher total genetic diversity among populations was observed in the hermaphroditic species in comparison to the dioecious F. vesiculosus.
