我们研究了暴露于海水平衡与富CO2的空气（CO2 2380 ppm）从卵到成熟的影响，并在随后的两个世代的桡足类Acartia tsuensis。与对照组（CO2 380 ppm）相比，第一代桡足类在所有生命阶段的高CO2暴露并没有显着影响生存，身体大小或发育速度。产卵量和孵化率也没有显着差异的第一代女性暴露于高CO2和第1和第2代女性从卵发育到成熟的高CO2。因此，桡足类似乎比先前研究的其他海洋生物对CO2耐受性更耐受CO2增加（即，海胆和双壳类）。然而，桡足类在海洋生态系统中的至关重要性需要彻底评估预计随着二氧化碳浓度增加而发生的海洋环境变化的总体影响，即，温度升高、紫外线照射增强以及浮游植物群落结构和营养价值的变化。(C)2008爱思唯尔有限公司保留所有权利。
We studied the effects of exposure to seawater equilibrated with CO2-enriched air (CO2 2380 ppm) from eggs to maturity and over two subsequent generations on the copepod Acartia tsuensis. Compared to the control (CO2 380 ppm), high CO2 exposure through all life stages of the 1st generation copepods did not significantly affect survival, body size or developmental speed. Egg production and hatching rates were also not significantly different between the initial generation of females exposed to high CO2 and the 1st and 2nd generation females developed from eggs to maturity in high CO2. Thus, the copepods appear more tolerant to increased CO2 than other marine organisms previously investigated for CO2 tolerance (i.e., sea urchins and bivalves). However, the crucial importance of copepods in marine ecosystems requires thorough evaluation of the overall impacts of marine environmental changes predicted to occur with increased CO2 concentrations, i.e., increased temperature, enhanced UV irradiation, and changes in the community structure and nutritional value of phytoplankton.
