| Outline of Final Research Achievements |
We corrected pelagic snail Limacina helicina from the subarctic western North Pacific and analyzed partial nucleotide sequences of the mitochondrial cytochrome c oxidase subunit I gene (COI). The data show clear genetic differentiation between populations in the North Pacific Ocean and North Atlantic Ocean. We then cultured them under the high pCO2 sea water for 10 days. We did not observe the clearly phenotypic effect, on the other hand, we found some shell-related genes were up-regulated by the high pCO2 environment.
