| Outline of Final Research Achievements |
For 22 butterfly species in Japan, I constructed the species distribution models (SDMs) considering climate, topography, land-use and the distribution of host plant species, and projected the future distribution under environmental change scenarios. Our models showed that climate is critical for the geographical range of Japanese butterflies. Also, land-use factors accounted for the distribution of some species. The contribution of the distribution of host plant species was high in 11 species. This indicates the importance of biotic interaction for SDM approach. The projection under environmental scenarios indicated that climate warming and land-use change affects both increase and decrease of range of butterfly species.
