| Outline of Final Research Achievements |
To elucidate characteristics of microbial community in its formation process, we crossed three termite species harboring species-specific symbiotic microbial compositions, and examined community structure of newly formed symbiont community of their hybrids. In most cases symbiont compositions in the hybrid termites converged to a stable composition of a particular parent species. Antibiotic treatment had significant negative effects on the establishment of symbiotic protist compositions of the hybrid colonies. These results probably reflect long-term complex co-adaptaion between symbiotic microorganisms. We also clarified effects of temperature on the sybiotic protist community structures and protist faunae of the field colonies of two host termite species.
