| Outline of Final Research Achievements |
We sampled seeds of an invasive species Cardamine hirsuta, which has invaded these four decades and spread in Japan, and those of a native species Cardamine scutata from two latitudinal gradients in East Japan. We studied genetic structure of populations and freezing tolerance. C. hirsuta populations were divided into four groups, suggesting that C. hirsute has invaded at least four times. Freezing tolerance was different between populations, which was correlated with minimum temperature. These results suggest that functional genetic differentiation has been occurred even in species that had invaded recently.
