| Outline of Final Research Achievements |
In this study, changes in species composition of the epilithic fungal community in Natori Rivers were examined using a PCR-DGGE method. The result showed that species composition and richness of epilithic fungal assemblages change along the longitudinal gradient of the river, which reflects the changes in types of organic matter derived from primary producers in the river and a variety of land uses and land covers in the drainage basin. A field experiment also showed that there were antagonistic relationships among fungal species, which was changed depending on supplies of different organic matter. These results provide a novel insight into ecological determinants of the diversity and structure of the epilithic fungi in lotic environments, and suggest that species composition of epilithic fungal community reflects quality and diversity of organic matter discharged into rivers.
