Calcification in a marginal sea – influence of seawater [Ca2+] and carbonate chemistry on bivalve shell formation

Data sets

Effects of seawater calcium on calcification in mussel larvae Jörn Thomsen, Kirti Ramesh, Trystan Sanders, Markus Bleich, and Frank Melzner

Short summary
The distribution of mussel in estuaries is limited but the mechanisms are not well understood. We document for the first time that reduced Ca2+ concentration in the low saline, brackish Baltic Sea affects the ability of mussel larvae to calcify the first larval shell. As complete formation of the shell is a prerequisite for successful development, impaired calcification during this sensitive life stage can have detrimental effects on the species' ability to colonize habitats.
