“…The hydrodynamic features of the English Channel may also be playing an important role in restricting the gene flow, separating Great Britain from northern France and connecting the North Sea to the Atlantic (Salomon & Breton, ). In the same area, a genetic break was also observed in other crustacean species, such as Carcinus maenas (Roman & Palumbi, ), Pollicipes pollicipes (Quinteiro, Rodríguez‐Castro, & Rey‐Méndez, ) or Palaemon elegans (Reuschel et al, ).…”

The common littoral shrimp Palaemon serratus is an ecologically and economically important decapod crustacean. Understanding the spatial structure of its populations is crucial to implement effective management strategies. In this study, 17 polymorphic microsatellite nuclear markers were examined in 252 individuals to explore the genetic diversity and the population structure underlying the geographical distribution of this crustacean in European waters. Basic genetic descriptors, population genetic analyses based on FST, analysis of the molecular variance (AMOVA), Bayesian clustering and the Mantel test were performed. Genetic differentiation was significant among sampling sites. AMOVAs and Bayesian assignment tests showed genetic differentiation among localities from the Atlantic coast and those belonging to the area of the Strait of Gibraltar and the Mediterranean Sea. The Guadalquivir estuary was significantly different from the remaining localities. A biogeographical break was detected to the west of the Strait of Gibraltar, and evidence of isolation by distance was obtained. Localities on both sides of the English Channel showed genetic differentiation with the rest of the Atlantic sampling sites, indicating a biogeographical break in this area. These results will contribute towards the better understanding of the biology and ecology of this shrimp and management of the valuable fishery. Two priority areas were delimited: the Atlantic and the Gibraltar–Mediterranean. The Guadalquivir estuary, Anglesey and Calais should also be considered as different genetic stocks.

“…Strong onshore currents from the Gulf Stream that flow east and south of the Cape, together with larval retention by oceanographic features within the Bay of Biscay (Gil, 2008), may be strong barriers to adult or juvenile dispersal by seahorses. Similarly, the Cape Verde frontal zone (Perez‐Rodriguez et al , 2001; Vangriesheim et al , 2003) has been observed to be a barrier to gene flow in sessile species (De Wolf et al , 2000; Quinteiro et al , 2007), as well as potentially highly dispersing species (Aboim et al , 2005), between European and West African Atlantic Ocean coasts. The findings from this study indicate that these barriers also apply to seahorses.…”

This first genetic study of Hippocampus hippocampus covers the species' entire geographic range and employs two mtDNA markers (control region and cytochrome b) to establish patterns of population structuring. A total of 255 specimens from 21 locations were used to obtain 89 concatenated haplotypes. The common haplotype was present in all but one population, however, most haplotypes were unique. The haplotype network had a star-like construction, suggesting expansion from a bottleneck event. F(ST) and AMOVA revealed population subdivision into three geographic regions (English Channel + Bay of Biscay, Mediterranean Sea + Atlantic Ocean Iberian coast + Macaronesian Islands, and West Africa) with barriers to gene flow indentified at Cape Finisterre and the Cape Verde frontal zone. Neutrality tests and nested clade analysis suggest a complex demographic history, with both historic events and contemporary processes shaping patterns of genetic differentiation. The genetic population subdivision detected in this study indicates that H. hippocampus should be managed as three separate units. This is especially pertinent as H. hippocampus populations within the West African region are the only ones known to be specifically targeted for exploitation.

“…Few studies have used population genetic data to determine the dispersal patterns of barnacles. The population genetics of P. pollicipes in the northeastern Atlantic (Quinteiro et al, 2007), the range of Tetraclita rubescens from Bahia Magdalena to Cape Mendocino (Dawson et al, 2010), and Tetraclita squamosa in East Asia (Chan et al, 2007) are influenced by coastal currents and hydrological barriers. However, the relationship between Korean coastal marine mammal intraspecific population genetics Table 1 for site names).…”

Genetic diversity and gene flow patterns in Pollicipes mitella were investigated with a nucleotide sequence analysis of 514 base pairs from the mitochondrial cytochrome c oxidase subunit I gene (COI) in 124 samples collected from six Korean populations. In total, 59 haplotypes were defined by 40 variable nucleotide sites in the COI region. The haplotypes had shallow haplotype genealogy and no geographic associations. All populations had high haplotype diversity (0.909 to 0.979) and low nucleotide diversity (0.0055 to 0.0098). The haplotypes with recently diverged nucleotides were distributed by long-range larvae dispersal among regional populations. The pairwise fixation indices (F ST ) estimated with the exact test and migration rates indicate that substantial gene flow has occurred among populations as a result of sea currents, except between the Uljin (East Sea coast) and other Korean populations. This suggests that significant genetic differentiation and low migration rates have affected the Uljin population.
