Abstract
The information about the algae of Lake Azas, a part of the water area of which belongs to the Azas State Nature Reserve, is reported for the first time. One hundred seventy one species and intraspecific taxa were identified referred to 72 genera, 50 families, and 8 divisions. The basis of the algal flora was found to consist of diatoms and blue-green algae. Fourteen dominants were identified, 9 of which belong to the Bacillariophyta microalgae. Ecological and geographical studies of the algae in the reserved part of the lake were carried out. The algal flora of the water body was found to be represented by benthic species with a prevalence of indifferent forms in relation to halobility and active reaction of the environment. One hundred twenty three species, indicators of water saprobity, were identified in all the biotopes studied. The predominance of betamezosaprobionts and oligosaprobionts was detected. Geographically, cosmopolitan and boreal species dominated.
期刊介绍：
Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
