Research Abstract |
Distributions of amphibians and reptiles in many islands of the Amami and Okinawa Groups were surveyed. An analysis using area-distance model showed that in a few species geographic distance from main-islands had a significant explanatory power for presence/absence of the species in an island, suggesting that overseas dispersals have taken some role in maintenance of island populations in those species. However, genetic analysis for a few species did not support this view.
