Abstract
AbstractFreshwater mussels belonging to the genus Nodularia (Family Unionidae) are known to be widely distributed in East Asia. Although phylogenetic and population genetic studies have been performed for these species, there still remain unresolved questions in their taxonomic status and biogeographic distribution pathways. Here, the nucleotide sequences of CO1 and 16S rRNA were newly determined from 86 N. douglasiae and 83 N. breviconcha individuals collected on the Korean Peninsula. Based on these data, we revealed the following results: (1) N. douglasiae can be divided into the three genetic clades of A (only found in Korean Peninsula), B (widely distributed in East Asia), and C (only found in the west of China and Russia), (2) the clade A is not an independent species but a concrete member of N. douglasiae given the lack of genetic differences between the clades A and B, and (3) N. breviconcha is not a subspecies of N. douglasiae but an independent species apart from N. douglasiae. In addition, we suggested the plausible scenarios of biogeographic distribution events and demographic history of Nodularia species.
