Seawater carbonate chemistry, fertilization rate and biological processes of sea urchin Paracentrotus lividus during experiments, 2011

Laure Moulin, Ana Isabel Catarino, Thomas Claessens & Philippe Dubois
The effect of pH ranging from 8.0 to 6.8 (total scale - pHT) on fertilization, cleavage and larval development until pluteus stage was assessed in an intertidal temperate sea urchin. Gametes were obtained from adults collected in two contrasting tide pools, one showing a significant nocturnal pH decrease (lowest pHT = 7.4) and another where pH was more stable (lowest pHT = 7.8). The highest pHT at which significant effects on fertilization and cleavage were...
