| Outline of Final Research Achievements |
There are 3 Habu species currently recognized in Japan: Protobothrops flavoviridis from the Amami Islands and the Okinawa Islands, P. tokarensis from the Tokara Islands, and P. elegans from the Yaeyama Islands. To survey their genetic divergence and diversity, we determined the complete mitogenome sequence (approx. 17 kb) from 44 specimens collected from 12 islands. The maximum likelihood tree showed a significant divergence between the Amami Clade and the Okinawa Clade. The Amami Clade also includes all specimens from the Tokara Islands currently known as an independent species, P. tokarensis, suggesting the paraphyly of the taxon, P. flavoviridis. In contrast, he validity of the taxon, P. elegans as an independent species was supported. By MCMC method, we estimated the divergence time between the Amami Clade and the Okinawa Clade to be 6.5 MYA, indicating that the vicariance of the two clades preceded the geological separation of the Amami Islands and the Okinawa Islands (~1.5MYA).
