| Abstract: | This paper clarifies the distribution and ecology of representatives of the genus Stuckenia (S. chakassiensis (Kaschina) Klinkova, S. pectinata (L.) Börner, S. macrocarpa (Dobroch.) Tzvelev, and S. vaginata (Turcz.) Holub) in brackish and saline lakes in eastern Russia. It is shown that S. chakassiensis grows in most Transbaikal lakes with a high salinity instead of S. pectinata, as was described earlier. Therefore, the range of this interesting and still insufficiently known taxon significantly extends to the east of Russia. Being very common in the mineralized waters of West Siberia, S. macrocarpa was not observed in Transbaikalia. In soda waters of Transbaikalia, S. chakassiensis forms thickets with a rather high productivity. |
