Outline of Final Research Achievements

Ranges of many species tend to move northward owing to recent global warming, but those of some species have not changed or reduced. In this study, we examined genetic population structures of 4 species in which the range boundaries recently moved to northward (north-moving species) and 3 species in which they have not changed (stationary species) over recent decades using genome-wide SNP markers. The results show that clear genetic divergence among local populations could be found in stationary species, but not in north-moving species. This indicated that the stationary species could not move to northward owing to local adaptation to factors other than temperature.
