摘要:
随着工业化进程的发展，温室气体二氧化碳（CO₂）大量排放，约四分之一被海洋吸收，导致海水pH值和碳酸钙饱和度降低，出现了海洋酸化的现象。海洋酸化及引起的碳酸盐化学体系的变化已对各种海洋生物产生影响。贝类作为海洋生态系统中的代表性生物类群，自身具有一定的酸碱平衡调节能力，但其属于钙化生物，极易受到海水酸化的影响。在对贝类进行酸化生理生态响应的研究中，我们发现海洋酸化影响到贝类整个生活史和几乎大部分生理过程，尤其是早期生活史阶段呈现高度敏感性。本文就目前国内外对贝类在酸化条件下的生理生态响应进行了综述和讨论，为贝类应对海洋酸化响应机制研究提供理论参考。

Abstract:
Since the industrial revolution, greenhouse gases have been released in increasing quantities, a quarter of which has dissolved into the sea, reducing the pH and calcium carbonate saturation of seawater. This phenomenon is called ocean acidification. Ocean acidification and the accompanying changes in the seawater carbonate system have a profound impact on marine life. As a typical biological group in the marine ecosystem, mollusks possess a certain capacity for acid-base regulation. However, as calcified organisms, these animals may be easily affected by seawater acidification. Based on the existing investigations of ecophysiological responses in mollusks, we have found that ocean acidification almost affects the entire life history and most physiological processes of mollusks, which especially show high sensitivity to acidification in the early life stage. In this review, we summarize and discuss the present research progress on ecophysiological responses to ocean acidification in mollusks, providing a theoretical reference for future studies on the responding mechanisms of mollusks to ocean acidification.
