| Outline of Final Research Achievements |
Effects of aphid and lacebug herbivory on reproductive success and flower visitor communities on tall goldenrods were investigated. Lacebug herbivory decreased flower number and floral nectar. In contrast, aphid herbivory increased them. Increased flowers increased abundance of pollinators and non-pollinators. Lacebug herbivory decreased seed production, while aphid herbivory increased it. Origin of Japanese goldenrods was explored using neutral genetic marker. We found that Japanese goldenrods came from Southeastern United States, and that genetic diversity has been maintained through gene flow since their establishment in Japan. Effects of diversity and selection in goldenrod genotypes from Honshu and Hokkaido were investigated. Although we did not find the diversity effect on plant growth, the selection effect in Hokkaido genotypes was detected. The diversity effect of plant genotypes was also found in aphid abundance.
