| Outline of Final Research Achievements |
In the field, species interact with other species, such as competitors, prey and predators, show adaptation by evolution and phenotypic plasticity and behavioral choice, and modify the environment to the one suitable for its own. A number of species strongly interacting with each other combined with their physical environments form an "ecosystem". To understand the structure and function of ecosystems, we performed theoretical and modeling study. Especially the following three aspects: (1) Life history evolution of species constituting an ecosystem and its impacts to the ecosystem. (2) Creation and loss of species diversity, and (3) study of coupled dynamics of human choice and ecosystem dynamics. We could obtained very illuminating results for each aspect of the project.
