Impact of elevated CO2 on phytoplankton growth and organic matter production

通过分离和现场浮游生物群落研究了二氧化碳浓度升高对浮游植物生长和有机质生产的影响。对CO2增加的反应因物种而异，并在不同的温度和光照条件下发生变化。虽然现场浮游生物群落对二氧化碳的增加没有表现出主要的反应，但在一些实验中观察到了明显的二氧化碳增加的趋势。未来海水中二氧化碳的增加可以在改变就地浮游植物群落和有机物的动态方面发挥重要作用。

Impacts of elevated CO2 on phytoplankton growth and organic matter production were examined using isolates and in situ plankton communities. Responses to the CO2 increase were species-specific and were altered in different temperature and light conditions. Although in situ plankton communities did not show major responses to the CO2 increase, clear trends to the CO2 increase were observed in some experiments. Future CO2 increase in seawater can play a significant role on altering the dynamics of in situ phytoplankton communities and organic matters.
