Abstract：
The shallow hydrothermal vents (HVs) of Kueishan Island are considered as a template for studying the extremes of sulfide-polluted and acidified water. The present study examined the biological and spatiotemporal aspects of mesozooplankton mortality in waters around this extreme HV environment. Zooplankton sample collection was carried out in three monsoonal periods and the results revealed that there was a significant decrease in the mortality of total mesozooplankton with increasing distance from the HVs. The overall mortality of mesozooplankton showed a significant negative correlation with sea surface temperature and pH. Particularly, mortality of copepods showed a significant negative correlation with pH, whereas it was significantly positive correlated with sea surface temperature in the southwest monsoon prevailing period. Overall, the results may imply a situation that zooplankton will encounter in the more acidified environment of a future ocean.
摘要：
奎山岛的浅层热液喷口（HVs）被认为是研究硫化物污染和酸化水极端的模板。本研究检查了这种极端HV环境周围水域中浮游动物死亡率的生物学和时空方面。浮游动物的样本收集是在三个季风时期进行的，结果表明，随着与HV的距离增加，总的中浮游动物的死亡率显着降低。中浮游动物的总死亡率与海表温度和pH值呈显着负相关。特别是,co足类的死亡率与pH呈显著负相关，而在西南季风盛行时期，它与海表温度呈显着正相关。总的来说,结果可能暗示浮游动物将在未来海洋更加酸化的环境中遇到的情况。
