Outline of Final Research Achievements

The aim of this study is to identify spatial patterns of genetic diversity of a threatened maple, Acer miyabei and examine its relationships with a regional landscape structure using circuit theory. Leaf samples were collected from 580 individuals of Acer miyabei in northern and central Japan. Twelve SSR markers were developed to determine genetic variation among the individuals and populations. I found a significant correlation between genetic distances among populations and resistance distances calculated by the theory. The result suggests that landscape features, such as degree of fragmentation of forests, strongly affect gene flows among natural populations of the species.
