Coral and mollusc resistance to ocean acidification adversely affected by warming
Increasing atmospheric carbon dioxide (CO2) concentrations are expected to decrease surface ocean pH by 0.3‐0.5 units by 2100 (refs 1,2), lowering the carbonate ion concentration of surface waters.
Early development and molecular plasticity in the Mediterranean sea urchin Paracentrotus lividus exposed to CO2-driven acidification
TLDR
Paracentrotus lividus appears to be extremely resistant to low pH, with no effect on fertilization success or larval survival, and plasticity at the gene expression level that allows a normal, but delayed, development under low pH conditions is revealed.
Response of the Arctic Pteropod Limacina helicina to Projected Future Environmental Conditions
TLDR
The results support the current concern for the future of Arctic pteropods, as the production of their shell appears to be very sensitive to decreased pH, and the decrease in calcium carbonate precipitation was highly correlated to the aragonite saturation state.
Impact of ocean acidification on a key Arctic pelagic mollusc ( Limacina helicina )
Abstract. Thecosome pteropods (shelled pelagic molluscs) can play an important role in the food web of various ecosystems and play a key role in the cycling of carbon and carbonate. Since they harbor
Assimilation and retention of metals in teleost and elasmobranch fishes following dietary exposure
TLDR
TTF, calculated by dividing the product of metal AE and ingestion rate (IR) by ke, exceeded 1 only for Mn, Zn and Cs, suggesting that these metals will not biomagnify in piscivorous fishes.
Effects of increased pCO2 and temperature on trace element (Ag, Cd and Zn) bioaccumulation in the eggs of the common cuttlefish, Sepia officinalis
TLDR
The results suggest that pH and temperature affected both the permeability properties of the eggshell and embryonic metabolism, and the need to further evaluate the likely ecotoxicological impact of the global change on the early-life stages of the cuttlefish.
