Seawater carbonate chemistry and mortality, growth, and net calcification rates of sea urchin Echinus esculentus

Here we evaluate the biological response (mortality, growth and net calcification rates) of a marine calcifier, the larvae of the sea urchin Echinus esculentus, to different levels of variability of pCO2/pH imposed in the absence or presence of seagrass and under 4 different pHs, relevant in the context of present natural variability and future ocean acidification.

本研究针对海洋钙化生物（marine calcifier）——食用海胆（Echinus esculentus）的幼体，评估其在两种环境处理下的生物学响应（包括死亡率、生长速率与净钙化速率）：一是在有或无海草（seagrass）存在的条件下，暴露于实验施加的不同幅度的pCO₂/pH波动环境；二是处于4种与当前自然波动及未来海洋酸化背景相关的pH水平环境中。
