| Outline of Final Research Achievements |
The structure and functions of the microbial food web in the rice rhizosphere, the hot spot of methane dynamics in a rice field ecosystem, were studied. Field surveys and pot and microcosm experiments revealed that the rice rhizosphere was inhabited by the specific members of heterotrophic protists (ciliates, flagellates, and amoeba) showing the community shift to the redox conditions and supply of organic matters in the environment. The structure of the microbial food web in the rice rhizosphere that was driven by methane oxidation was also distinct from that of bulk soil.
