Abstract: | The variability of mtDNA in four Far Eastern endemic species of the genus Tribolodon was studied in the significant part of their areas. There was no close relationship between the lifetime and the level of mtDNA variability. The relation between the population genetic structure and the level of amphidromic species was revealed. The presence of mtDNA phylogroup differed in three of the four species shows that there was a long period of independent intraspecific divergent evolution in the history of these species. This period falls on aproximately the same historical age, and, apparently, is caused by one and the same factors. The period was not enough long and ended in the integration of genetically independent units into a single species. |
