Outline of Final Research Achievements

The existence of ecology-evolutionary feedback, in which ecological dynamics such as population dynamics and evolutionary dynamics of adaptation are closely related, is increasingly demonstrated in various systems. This research deepened its understanding from a new perspective of details of intra-specific diversity. The results showed that slight differences in genetic diversity can cause very different evolutionary and ecological dynamics. This implies that qualitative differences in genetic diversity can have a major impact on ecosystems and the importance of considering genetic diversity more than previously thought.
