| Research Abstract |
We assessed food sources and population and genetic structure of macrozoobenthos in tidalflat and salt-marsh ecosystems. In Mutsu Bay, genetic diversity of the endangered gastropod Batillaria multiformis was relatively high, and the local population included a younger cohort. We also compared the food sources of macrozoobenthos between tidalflat and salt-marsh habitats using stable C and N ratios, and found a significant difference between the habitats ; i.e., marsh plant derived organic matter was utilized more in the salt marsh habitat.
