Experimental influence of pH on the early life-stages of sea urchins I: different rates of introduction give rise to different responses
Many early life-stage response studies to ocean acidification utilize gametes/offspring obtained from ambient-sourced parents, which are then directly introduced to experimentally altered seawater pH. This approach may produce a stress response potentially impacting development and survival. Hence,...
