Origins of Semisulcospira libertina (gastropoda: semisulcospiridae) in Taiwan.

Mitochondrial DNA A DNA Mapp Seq Anal 2017 07 8;28(4):518-525. Epub 2016 Mar 8.

f Department of Biology, The Affiliated School of National Tainan First Senior High School , Tainan , Taiwan.

The most accepted hypothesis has suggested that the fauna in Taiwan Island originated from South China, but some studies supported the Japan, Ryukyu Archipelago, and Taiwan Islands as a unique biogeographical district. This study examines whether the populations of freshwater snail Semisulcospira libertina in Taiwan are closer to those in Japan based on the mitochondrial cytochrome c oxidase subunit I (COI) gene sequences. Our study shows the populations in North Taiwan originated from Japan and the cyclic glacial caused the migrations among islands and continent repeatedly; the populations in South Taiwan might originate from South China or South Asia.
