The European lobster ( Homarus gammarus ) forms the base of an important fishery along the coasts of Europe. However, stocks have been in decline for many years, prompting new regulations in the fishery and also restocking efforts. An important feature of any restocking effort is the assessment of success in the number of released juveniles that stay and become adult over time. Here, we tested the power of a single nucleotide...

Ocean acidification is expected to decrease calcification rates of bivalves. Nevertheless, in many coastal areas high p CO 2 variability is encountered already today. K iel F jord ( W estern B altic S ea) is a brackish (12–20 g kg −1 ) and CO 2 enriched habitat, but the blue mussel M ytilus edulis dominates the benthic community. In a coupled field and laboratory study we examined the annual p CO 2 variability in this habitat...
