Abstract [Related Publication]: Ocean acidification poses a range of threats to marine invertebrates; however, the emerging and likely widespread effects of rising carbon dioxide (CO2) levels on marine invertebrate behaviour are still little understood. Here, we show that ocean acidification alters and impairs key ecological behaviours of the predatory cone snail Conus marmoreus. Projected near-future seawater CO2 levels (975 µatm) increased activity in this coral reef molluscivore more than threefold (from less than 4 to more than 12 mm min−1) and decreased the time spent buried to less than one-third when compared with the present-day control conditions (390 µatm). Despite increasing activity, elevated CO2 reduced predation rate during predator–prey interactions with control-treated humpbacked conch, Gibberulus gibberulus gibbosus; 60% of control predators successfully captured and consumed their prey, compared with only 10% of elevated CO2 predators. The alteration of key ecological behaviours of predatory invertebrates by near-future ocean acidification could have potentially far-reaching implications for predator–prey interactions and trophic dynamics in marine ecosystems. Combined evidence that the behaviours of both species in this predator–prey relationship are altered by elevated CO2 suggests food web interactions and ecosystem structure will become increasingly difficult to predict as ocean acidification advances over coming decades.

【相关文献摘要】海洋酸化（Ocean acidification）对海洋无脊椎动物存在多维度威胁；然而，二氧化碳（CO₂）浓度升高对海洋无脊椎动物行为产生的新兴且可能广泛存在的影响，目前仍鲜为人知。本研究证实，海洋酸化会改变并损害捕食性芋螺（Conus marmoreus）的关键生态行为。相较于当前对照条件下的海水CO₂浓度（390 µatm），预测的近未来海水CO₂水平（975 µatm）可使该珊瑚礁食软体动物类群的活动量提升三倍以上（从不足4 mm·min⁻¹增至12 mm·min⁻¹以上），并将其潜伏时长缩减至原来的三分之一以下。尽管活动量有所提升，但高CO₂浓度处理组的捕食者在与对照处理的驼背凤凰螺（Gibberulus gibberulus gibbosus）进行捕食互动时，捕食率显著下降：对照组中有60%的捕食者成功捕获并取食猎物，而高CO₂浓度处理组仅为10%。近未来海洋酸化对捕食性无脊椎动物关键生态行为的改变，可能对海洋生态系统中的捕食者-猎物相互作用及营养动态（trophic dynamics）产生深远影响。鉴于该捕食者-猎物关系中两个物种的行为均因高CO₂浓度升高而发生改变的联合证据，未来数十年随着海洋酸化持续加剧，食物网相互作用与生态系统结构将愈发难以预测。
