详细
Baikal endemic Benedictia fragilis gastropods distributed in a wide range of depths (from sublittoral to abyssal) of three lake basins are studied. The analysis of the nucleotide sequence of the COI mitochondrial gene fragment and internal transcribed nuclear DNA spacer (ITS1) demonstrates that the studied gastropods are represented in Lake Baikal by three genetic groups. The results of the studies on genetic diversity, phenotypic traits, and distribution allow us to assume that the detected groups are incipient allopatric (geographical) species. On the basis of the data obtained and geological and climatic history of Baikal, possible pathways of the B. fragilis resettlement in the lake and the emergence of three genetic groups are hypothesized.
