Intra-population variability of ocean acidification impacts on the physiology of Baltic blue mussels (Mytilus edulis): integrating tissue and organism response

Increased maintenance costs at cellular, and consequently organism level, are thought to be involved in shaping the sensitivity of marine calcifiers to ocean acidification (OA). Yet, knowledge of the capacity of marine calcifiers to undergo metabolic adaptation is sparse. In Kiel Fjord, blue mussels thrive despite periodically high seawater PCO2, making this population interesting for … Continue reading Intra-population variability of ocean acidification impacts on the physiology of Baltic blue mussels (Mytilus edulis): integrating tissue and organism response

The biochemical response of two commercial bivalve species to exposure to strong salinity changes illustrated by selected biomarkers

Salinity is a major controlling factor in estuarine systems whose fast change, namely during the occurrence of extreme climatic events, causes drastic alterations on aquatic communities by promoting a physiologically stressful environment. The response of fatty acid (FA) and antioxidant enzymes’ activity (Glutathione S-transferase (GST) and Superoxide dismutase (SOD)) of Cerastoderma edule and Scrobicularia plana … Continue reading The biochemical response of two commercial bivalve species to exposure to strong salinity changes illustrated by selected biomarkers

Growth, Survival and Reproduction of the Giant Clam Tridacna maxima (Röding 1798, Bivalvia) in Two Contrasting Lagoons in French Polynesia

Shell growth, reproduction, and natural mortality of the giant clam Tridacna maxima were characterized over a two-year-period in the lagoon of the high island of Tubuai (Austral Archipelago) and in the semi-closed lagoon of Tatakoto (Tuamotu Archipelago) in French Polynesia. We also recorded temperature, water level, tidal slope, tidal range, and mean wave height in … Continue reading Growth, Survival and Reproduction of the Giant Clam Tridacna maxima (Röding 1798, Bivalvia) in Two Contrasting Lagoons in French Polynesia
