海洋钙化生物的早期生命阶段特别容易受到气候变化的影响。在南大洋，文石不饱和事件和迅速变暖的地区已经发生，预计其程度还会增加。在这里，我们提出了第一项研究，成功孵化的极地翼足类Limacina helicina anapartica和观察暴露于温度升高和文石欠饱和导致海洋酸化（OA）的早期生命阶段的生存和壳形态的潜在影响。在暴露于扰动条件下的个体中观察到高幼虫死亡率（高达39%）。升温和OA分别引起广泛的壳畸形和溶解，增加壳的脆性。此外，壳生长下降，与治疗和曝光时间之间的变化。我们的研究结果表明，短期暴露通过热点的OA和变暖构成了严重的威胁翼足类动物招聘和长期的人口生存能力。本文的在线版本（10.1007/s 00227 -017-3261-3）包含补充材料，可供授权用户使用。
Early life stages of marine calcifiers are particularly vulnerable to climate change. In the Southern Ocean aragonite undersaturation events and areas of rapid warming already occur and are predicted to increase in extent. Here, we present the first study to successfully hatch the polar pteropod Limacina helicina antarctica and observe the potential impact of exposure to increased temperature and aragonite undersaturation resulting from ocean acidification (OA) on the early life stage survival and shell morphology. High larval mortality (up to 39%) was observed in individuals exposed to perturbed conditions. Warming and OA induced extensive shell malformation and dissolution, respectively, increasing shell fragility. Furthermore, shell growth decreased, with variation between treatments and exposure time. Our results demonstrate that short-term exposure through passing through hotspots of OA and warming poses a serious threat to pteropod recruitment and long-term population viability.
