Outline of Final Research Achievements

Volcanic eruptions offer great opportunities for understanding of terrestrial ecosystem formation. In this study, we investigated the 2000 eruption-affected sites and analyzed the newly exposed volcanic substrates in the island of Miyake. Our results showed that iron-oxidizing chemolithoautotrophic bacteria were pioneer microbes and played an important role in the input of carbon and nitrogen from the atmosphere. We identified Miscanthas condensatus as a major pioneer plant after the 2000 eruption. The rhizosphere bacterial community of this plant was predominated by Beta- and Gammaproteobacteria and gradually replaced by Alphaproteobacteria and Actinobacteria in response to the increase in the plant cover percentage. Bradyrhizobium, Rhizobium, Granulicella, and Arthrobacter were assumed as key microbes in the pioneer plant colonization. In conclusion, our study revealed the relationships between soil formation, vegetation development, and microbial community structure.
