| Outline of Final Research Achievements |
Unraveling the Anthropogenic impacts such as global warming and ocean acidification on marine ecosystem processes are urgent issues. This study examined the effects of temperature and high CO2 conditions on biodiversity of marine phytoplankton communities in the subarctic Pacific and western Arctic Ocean. The major finding of this study is that natural phytoplankton communities consists of many kinds of ecological niche which supports primary productivity under different environmental conditions. However, environmental perturbation especially warming decreases the biodiversity of phytoplankton, indicating that the robustness of marine ecosystem productivity could decrease with the further additive perturbations.
