The Gulf of Guinea (GoG) is host to many distinct ecosystems, among which is the Guinea Current Large Marine Ecosystem extending from the intense upwelling area of the Guinea Current in the north to the Benguela Current in the south. The GoG region is however, characterized by a high poverty rate within fishing communities, with […]
Fertilization and early development are usually the most vulnerable stages in the life of marine animals, and the biological processes during this period are highly sensitive to the environment. In nature, sea urchin gametes are shed in seawater, where they undergo external fertilization and embryonic development. In a laboratory, it is possible to follow the […]
Biomolecules play key roles in regulating the precipitation of CaCO3 biominerals but their response to ocean acidification is poorly understood. We analysed the skeletal intracrystalline amino acids of massive, tropical Porites spp. corals cultured over different seawater pCO2. We find that concentrations of total amino acids, aspartic acid/asparagine (Asx), glutamic acid/glutamine and alanine are positively […]
Highlights • Fluctuating pCO2/pH doubled copper-induced antioxidant activity and DNA damage in mussels. • In contrast, fluctuating conditions mitigated some of the effects of copper for ragworms. • These effects were associated with the differing acid-base physiology of the two species. • Physiology was as important as changing copper chemistry in determining overall toxicity. Abstract […]
Mesocosm experiments have been fundamental to investigate the effects of elevated CO2 and ocean acidification (OA) on planktic communities. However, few of these experiments have been conducted using naturally nutrient-limited waters and/or considering the combined effects of OA and ocean warming (OW). Coccolithophores are a group of calcifying phytoplankton that can reach high abundances in […]
