The History of Manayunkia [Polychaeta: Sedentaria: Sabellidae] propagation in North Eastern Asia

This study aimes to elucidate the history of propagation of the freshwater Manayunkia polychaetes in North-Eastern Asia and their speciation in Lake Baikal. Nucleotide polymorphism analysis of of the CO1 Folmer fragment allowed to establish the sequence of migration and speciation events. Phylogenetic analysis and bayesian comparison of possible scenarios supports the hypothesis that the origin of the Manayunkia migration was the Kolyma river basin, from where the polychaetes migrated into Baikal and diverged into at least three species, one of which (M. godlewskii) served as the source of migrants into the Lake Baunt system.
