| dc.description.abstract | Sylvirana guentheri, a species of Ranidae, widely distributes across southeastern China, Taiwan, and Vietnam. As amphibians, the migration is limited by geographical barriers, resulting in population differentiation. The purpose of our research is to use the DNA sequences of mitochondria and nuclear genes as molecular genetic markers to examine the phylogeography among the populations of S. guentheri, and to investigate the possible dispersal modes and migration paths of S. guentheri in East and Southeast Asia. The dataset includes newly acquired sequences of samples collected in Taiwan, and those of other regions’ samples from NCBI. Three mitochondrial gene regions and one nuclear gene region (12S rRNA, 16S rRNA, Cytochrome b, and CXCR4) were used, to reconstruct phylogeny. Based on our results, there are population variation among different areas, such as the population of S. guentheri in western Taiwan is obviously different from the population in eastern Taiwan. In addition, our results support that S. guentheri might originate in Southeast Asia and extend northward through Hainan to Taiwan. Later, there was another dispersal northward from Vietnam. | en_US |
