| Outline of Final Research Achievements |
Understanding factors controlling community stability is a central issue in ecology. Traditionally, the role of parasites in ecosystems has been considered to be negligible, but recent studies are changing this implicit assumption. In this research project, we found the possibility that manipulative parasites can make food webs top-heavy by enhancing the energy flow between hosts and/or hosts and other community members, which may destabilize communities, according to a recent theory for community stability.
