最近，大气二氧化碳增加导致海洋加速酸化和全球变暖，可能对海洋动物的生理和生态产生影响。本研究旨在确定Acartiaohtsukai的产卵率（EPR）和孵化成功率（EHS），以应对温度升高和pH值降低的综合影响。Acartiaohtsukai于2017年9月在韩国西北部的Yeoja湾收集了新鲜表层海水。所应用的温度和pH条件包括两个不同的pH水平（代表当前：7.9和未来：7.6）和三个温度值（26 °C、28 °C和30 °C）。在pH7.9时，EPR随温度的升高而显著升高，而在pH7.6时，EPR随温度的升高而显著降低。EHS在pH 7.6中低于pH 7.9。这些结果表明，由于全球变暖和海洋酸化的海洋环境的变化可能会影响Acartia种群，并导致Acartia属桡足类的整体波动。
The recent accelerated ocean acidification and global warming caused by increased atmospheric carbon dioxide may have an impact on the physiology and ecology of marine animals. This study was conducted to determine the egg production rate (EPR) and hatching success (EHS) of Acartia ohtsukai in response to the combined effects of an increase in temperature and a lower pH. Acartiaohtsukai with fresh surface seawater were collected in the northwestern Yeoja Bay of Korea in September 2017. The temperature and pH conditions applied included two different pH levels (representing the present: 7.9 and the future: 7.6) and three temperature values (26 °C, 28 °C, and 30 °C). In the pH 7.9, EPR significantly increased with increased temperature, but in pH 7.6, it significantly decreased as the temperature increased. EHS was lower in pH 7.6 than in pH 7.9. These results suggest that changes in the marine environment due to global warming and ocean acidification may affect Acartia populations and cause overall fluctuations in copepods of the genus Acartia.
