  • 27.07.2017: Ocean acidification hampers sperm-egg collisions, gamete fusion, and generation of Ca2+ oscillations of a broadcast spawning bivalve, Tegillarca granosa

    Although the effect of ocean acidification on fertilization success of marine organisms is increasingly well documented, the underlying mechanisms are not completely understood. The fertilization success of broadcast spawning invertebrates depends on successful sperm-egg collisions, gamete fusion, and standard generation of Ca2+oscillations. Therefore, the realistic effects of future ocean pCO2 levels on these specific aspects of fertilization […]

  • 27.07.2017: Altered sediment biota and lagoon habitat carbonate dynamics due to sea cucumber bioturbation in a high-pCO2 environment

    The effects of global change on biological systems and functioning are already measureable, but how ecological interactions are being altered is poorly understood. Ecosystem resilience is strengthened by ecological functionality, which depends on trophic interactions between key species and resilience generated through biogenic buffering. Climate-driven alterations to coral reef metabolism, structural complexity and biodiversity are […]

  • 26.07.2017: Presentation: “Climate change and ocean acidification”, INDEMER international conference, Monaco (video)

    Presentation on climate change and how it relates to ocean acidification given by Dr Lydia Kapsenberg, post-doctoral researcher, National Science Foundation (USA) & Centre National de la Recherche Scientifique (France), in the framework of the international conference “Knowledge of the ocean at the service of sustainable development”, 27-28 April 2017, Monaco, co-organized by INDEMER and […]

  • 26.07.2017: Carbon and nitrogen allocation strategy in Posidonia oceanica is altered by seawater acidification

    Rising atmospheric CO2 causes ocean acidification that represents one of the major ecological threats for marine biota. We tested the hypothesis that long-term exposure to increased CO2 level and acidification in a natural CO2 vent system alters carbon (C) and nitrogen (N) metabolism in Posidonia oceanica L. (Delile), affecting its resilience, or capability to restore the physiological homeostasis, […]

  • 26.07.2017: Effect of ocean acidification on growth, calcification, and gene expression in the pearl oyster, Pinctada fucata

    In this study, shell growth, shell microstructure, and expression levels of shell matrix protein genes (aspein, n16, and nacrein) that play a key role in the CaCO3 crystal polymorphism (calcite and aragonite) of the shell were investigated in the pearl oyster Pinctada fucata at pH 8.10, 7.70, and 7.40. We found that the shell length and total weight index did […]

  • 26.07.2017: Iron sources alter the response of Southern Ocean phytoplankton to ocean acidification

    The rise in anthropogenic CO2 and the associated ocean acidification (OA) will change trace metal solubility and speciation, potentially altering Southern Ocean (SO) phytoplankton productivity and species composition. As iron (Fe) sources are important determinants of Fe bioavailability, we assessed the effect of Fe-laden dust versus inorganic Fe (FeCl3) enrichment under ambient and high pCO2 […]
