摘要
利用实验生态学方法及透射电子显微镜技术对培养于CO2酸化海水中的中华哲水蚤和刺尾纺锤水蚤肌肉和卵母细胞超微结构进行了观察。结果表明:两种桡足类肌丝排列的有序性均随酸化的加剧而降低,较高CO2浓度海水会对桡足类产生一定程度的氧化损伤;桡足类卵母细胞的电子密度随酸化的加剧而降低,球形颗粒出现内缩或瓦解,酸化可能会导致桡足类卵母细胞发生过量凋亡,从而影响卵的质量。
The muscle and oocyte ultrastructure of Calanus sinicus and Acartia spinicauda which exposed to CO2-driven acidified seawater in laboratory-controlled were observed under the transmission electron mi eroscopy. The results showed that the orderly of myoneme of these two copepods were decreased with the concentration of CO2 increased. The higher Cco2 (0.20%,0,0.50 % and 1.00 %) had oxidative damage on the copepods. The electron-dense of oocytes of copepods were decreased with the increased cc%. The spherical granule were concentrated or collapsed. The elevated Cc% could induce the apoptosis and impact the quality of eggs of copepods.
