Abstract
For the first time, data are presented on the algae of the Khut River and its tributary, the Shivilig River, which flow in the Khutinsky State Nature Reserve of republican significance. A list of algae is given, including 157 species and intraspecific taxa belonging to 62 genera, 33 families, and 6 divisions. It has been established that the algoflora is mainly represented by diatoms and blue-green algae. The common dominants were identified for two rivers: Meridion circulare, Diatoma mesodon, D. hiemale, Hannaea arcus, and Didymosphenia geminata. Algae from the rivers of the reserve are compared. An ecological and geographical analysis of algae from the Khut and Seiba rivers with the Shivilig and Khon tributaries is carried out. It has been established that the algoflora of the reserve is represented by benthic species, with a predominance of indifferent forms in relation to the halobility and pH of water. In all watercourses studied, 133 species were identified that are indicators of water saprobity. The predominance of betamesosaprobionts and oligosaprobionts was noted. Cosmopolitans and boreal species dominated geographically.
