Abstract :クサフグを本州,四国,九州および沖縄島より採集し,マイクロサテライトDNA多型を用いて遺伝的多様性と分化の程度を調べた.沖縄島の標本群の有効アリル数の平均値は10.0で,他の標本群の14.2–16.5と比較して低かった.沖縄島の標本群は他の全ての標本群との間で黒潮による障壁が原因と考えられる遺伝的異質性が認められた.また,足摺岬周辺の標本群と他の標本群との間でも異質性が認められた.
Genetic diversity and divergence of the grass puffer Takifugu alboplumbeus in the Japan Arc (Honshu Island, Shikoku Island, Kyushu Island and Okinawa-jima Island) were surveyed using four microsatellite loci. Average allelic richness of Okinawa-jima Island was 10.0, being lower than richness (14.2–16.5) of the other populations. Significant genetic difference was observed between the Okinawa-jima Island population (ONS) and the other populations caused by the Kuroshio barrier. Significant genetic differences were also observed between Ashizuri (southwest Shikoku Island; KTM and KTS) populations and the other populations.
