| Outline of Final Research Achievements |
We analyzed the data of intertidal rocky-shore malacofauna recorded 13 times during 1978 to 2014 in Japan encompassing Hokkaido to Kyushu areas. We found correlations between the scales of malacofaunal change and the physical scales of the Great Tohoku Earthquake. That is, the shores with greater tsunami maximum height and seismic scale showed a pattern that species richness in a unit area increased and correspondingly species composition greatly changed after the quake. In addition, those shores exhibited more unstable fluctuations in species richness per unit area and in species composition after the quake.
