| Outline of Final Research Achievements |
This study aims to verify a phylogeographical hypothesis of “Daito islands corridor hypothesis” which is a working hypothesis explaining construction mechanism of shallow water ichthyofauna in southern Japan, based on genome wide analyses. We surveyed ichthyofauna around the Daito and Ogasawara islands, and carried out single nucleotide polymorphism (SNP) detection and genotyping on the Wrong-iron butterflyfish by using massive parallel sequencing technologies. 2278 SNPs in the genomes were genotyped. Genetic population structure analyses based on newly identified SNPs reveled presence of gene flow between Daito and Ogasawara islands. This result supports “Daito islands corridor hypothesis”. In addition, we established the efficient procedures conducting genome wide analyses in a small-scale research project for the phylogeographic research.
