| Outline of Final Research Achievements |
We aimed to elucidate the relationship between flow regime and river faunal composition across Japanese rivers. Our results showed that the duration of high flow events and the magnitude of spring flood have strong influence on the community structure of stream-dwelling invertebrate and fish in Japanese rivers. We concluded that environmental flow management, such as improvement of dam operation and mitigation of the impact of human land use, is essential for river ecosystem conservation.
