Physio-biochemical effects and mechanisms of acidified seawater on several copepods

Abstract

由于海水对CO2的吸收以及海洋封存CO2导致的海水酸化已经成为全球性的环境问题,其不仅引起海水化学性质的改变,而且对海洋生物的生存、生长和繁殖产生影响。浮游动物在海洋物质循环和能量流动中占有重要地位,研究浮游动物对海水酸化的响应将有助于我们更好的理解海水酸化对生物产生的影响。本研究选取中华哲水蚤、太平洋纺锤水蚤、刺尾纺锤水蚤、瘦尾胸刺水蚤等几种桡足类作为研究对象,比较CO2酸化和HCl酸化对桡足类的24h和48h的急性毒性(LC50pH),并分析二者之间的差异;采用实验生态学的方法,研究了为期8d不同酸化水平(pCO2800、2000、5000和10000ppm)对桡足类存活率、产卵率以及卵孵...Ocean acidification induced by absorbing CO2 or sequestration CO2 into the deep-sea has become a serious environmental issue. It’s not only changed the seawater chemical characteristic, but also impacted the survival, growth and reproductive performance of marine organisms. Zooplankton, as one of the most important parts of marine organisms, plays an indispensable role during the marine material c...学位:理学博士院系专业:海洋与环境学院海洋学系_海洋生物学学号:2242007015357
