Abstract
Data on yellow-green algae (Xanthophyta) from reservoirs and watercourses of the Azas State Nature Reserve has been processed and summarized. Lake Azas is located in the Todzhen basin of the Republic of Tyva, where representatives of this department currently count 10 species of algae. For the first time, 6 species are listed for water bodies of Tyva. Five species have been noted that have a limited distribution in Russia. Based on original and literary data, to date, 36 species have been identified in the water bodies of the Republic, represented by 39 species and infraspecific taxa from the Xanthophyta department, belonging to 7 families and 11 genera. The results of an analysis of data on the ecology and geographic distribution of representatives of this department are presented, and information is provided in relation to halicity, the active reaction of water, and saprobity.
