In situlong-term monitoring of cardiac activity of two bivalve species from the White Sea, the blue mussel Mytilus edulisand horse mussel Modiolus modiolus
Abstract Cardiac activity of two White Sea Bivalvia species – Mytilus edulis and Modiolus modiolus – was monitored in situ for one full calendar year every 4 days. During the year, we also assessed the temperature and salinity of the ambient seawater (at intervals of 1 min), measured phytoplankton c...
