Abstract / Notes
"Planarians of Baikal origin, subendemics, found in the Boguchany Reservoir, which is located more than 1000 km away from Lake Baikal, were described. The sampled specimens were referred to four genera. The genus Bdellocephala De Man 1875 was represented by the species Bdellocephala angarensis (Gerstfeldt 1858), Archicotylus Korotneff 1912 by the species Archicotylus decoloratus (Korotneff 1912), Microarchicotylus Timoshkin et Porfiriev 2015 by juvenile planarian specimens, and Baikalobia Kenk 1930 by the species Baikalobia raddei (Sabussov 1911). Of special interest is the finding of B. raddei, because this species has hitherto never been recorded in Lake Baikal. all previous reports having been confined to the mouth of Angara River. For many years, this latter fact was used to substantiate the hypothesis of a non-Baikal origin of all Baikalobia planarians. In this study, the phylogenetic analysis of B. raddei, as well as the planarians of the genera Archicotylus, Microarchicotylus, Rimacephalus, Baikaloplana, and Bdellocephala, was performed based on several regions of the ribosomal genes ITS1, 5.8S and ITS2. The morphological and physiological characteristics that enabled some Baikal planarians to leave the lake and get adapted to new ecological conditions is an area of further research."| Home page -- (Main hierarchy) |
