Abstract
For the first time, information about the algae of the Tapsa River is presented in the Tapsinsky State Nature Reserve of national significance. A list of algae has been compiled, including 103 specific and intraspecific taxa, which belong to 50 genera, 28 families and 6 divisions. It has been established that the algoflora is based on diatoms. 9 dominants have been identified. A comparison of the algoflora of the Tapsa River and the Hutinsky Nature Reserve was carried out. An ecological and geographical analysis of the algae of these watercourses has been performed. It has been established that the algoflora of rivers is represented by benthic species, with a predominance of indifferent forms in relation to the need and active reaction of the environment. 137 types of saprobicity indicators were identified in all the studied watercourses. The predominance of betamesosaprobionts and oligosaprobionts was noted. Geographically, cosmopolitan and boreal species dominated.
