Experimental influence of pH on the early life-stages of sea urchins II: increasing parental exposure times gives rise to different responses
Many studies into the responses of early life-stages to ocean acidification utilise offspring obtained from parents reared under present-day conditions. Their offspring are directly introduced to altered-pH conditions. This study determined whether this approach is suitable by pre-exposing parent se...
