| Research Abstract |
Mutualistic relationships between organisms are best views as selfish interactions that nonetheless result in net benefit to each patner. However, mutualisms are vulnerable to invasion by individuals that overexploit the benefit while paying less of the cost, which eventually leads to the collapse of the mutualism. In this study, I used plant-pollinator mutualism as a model system and suggested the possibility that a third-party organism (parasitoid of the pollinator) can prevent overexploitation by the pollinator, thereby contributing to the long-term stability of the mutualism.
