Research Abstract

Three of five Lefua(eight-barbel loach) species are assigned to endangered species. We showed, by mitochondrial and nuclear DNA sequencing, that a possibly new species inhabiting the Tokai district was more closely related to Lefua echigonia than to Lefua sp., although the species is morphologically and ecologically similar to Lefua sp. These results indicated parallel evolution between the species and Lefua sp. due to adaptation to montane streams. The species, as well as 7 populations of Lefua echigonia and 2 populations of Lefua sp., should be protected as evolutionary significant units. The species is threatened by dam construction. To save the species, we studied the species and its habitats ecologically and genetically and prepared for transfer of the species from quenching habitats due to dam construction to appropriate sites for protecting the species.
