TL;DR: In this paper, the impact of changes in the carbonate chemistry was investigated on Limacina helicina, a key species of Arctic ecosystems, and the pteropods were kept in culture under controlled pH conditions corresponding to pCO2 levels of 350 and 760 μatm.

TL;DR: 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.

TL;DR: 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.

TL;DR: Overall, it appears that it is possible to account for the major processes governing metal accumulation from food and water in marine copepod populations using a first order bioenergetic-based kinetic model.

TL;DR: Food is the likely primary pathway for Zn and Cd bioaccumulation in S. officinalis, and the digestive gland plays a major role in the subsequent storage and presumed detoxification of these elements regardless of the uptake pathway, tracer experiments indicate.
