| Research Abstract |
This study aimed to understand fine-scale spatial distributions of different chromosomal races and spatial variation of genetic structure in the two Podisma species distributed in Japan. As for the study of P.sapporensis in Hokkaido, intimate field studies have revealed that the envelope of the hybrid zone between different chromosomal races, if ever, will be so narrow (i.e. <3km). Landscape genetic studies on the populations of P.kanoi demonstrated that the degree of genetic differentiation between localities is not necessarily correlated with geographic distance.
