Phylogeography of the rice frog, Fejervarya multistriata (Anura: Ranidae), from China based on mtDNA D-loop sequences.
The rice frog, Fejervarya multistriata, is an amphibian widely distributed in China. In this study, we sampled the species across its distributional area in China and sequenced the mtDNA D-loop to investigate the genetic diversity and geographical pattern of the frog population. The results revealed 38 haplotypes in the population, with K2P values varying from 0.19% to 4.22%. Both a phylogenetic analysis and a nested clade analysis (NCA) detected two geographically isolated lineages respectively distributed around the Yangtze drainage (Yangtze lineage) and the south of China (southern lineage). NCA inferred a contiguous range expansion within the Yangtze lineage and allopatric fragmentation within the southern lineage, which might be partly due to the limited samples from this lineage. Accordingly, Fu's Fs test also indicated a population expansion after glacial movement. Therefore, we assumed that the species history responding to glacial events shaped the present population pattern of F. multistriata on the Chinese mainland.
