Impacts of CO2-driven seawater acidification on survival, egg production rate and hatching success of four marine copepods
State Oceanic Administration Foundation of China [200805029] Ecological experiments were conducted to examine the effects of seawater containing elevated partial pressure of carbon dioxide (p(CO2) 800x10(-6), 2 000x10(-6), 5 000x10(-6) and 10 000x10(-6)) on the survival and reproduction of female Ac...

There were significantly negative impacts on the egg hatching success of A. spinicauda and C. tenuiremis in the p(CO2) 2 000x10(-6) and 10 000x10(-6) groups, and, in addition, the exposure time had noticeably impacts on these rates too.
