It was considered not only the ratio between the abundance of species, but also the size-ecological groups of diatoms in the structure and composition of communities. At 9 stations in the western, northern, and northeastern parts of the lake, at depths of 8.4–558 m, a total of 155 taxa of diatoms were found, adapted to dwelling on the bottom (48–89 taxa per station, an average of 66.56). With increasing of the depth, a general decline in species wealth was noted. At a depth of 558 m, the number of species was 49 (48 per 145.5 m). The average qualitative similarity of communities made 60,11%, while the set of species from site to site did not varied extremely. The structural diversity of taxocenes was everywhere high (H` = 3.052–3.782, on average 3.473), and the role of dominants was rather weak (PIE = 0.898–0.966, on average 0.938).

Initially, the method was developed in the study of diatom complexes from modern lake sediments of the European part of Russia. Three initial types of taxonomic proportions of diatom complexes and three scenarios of their transformation have been established. Later, the method was successfully applied in the study of diatom complexes from Late Holocene deposits. The basic concepts and solving information tasks were formulated. Later, this made it possible to successfully analyze long-term transformations in river phytoplankton communities (biomonitoring). A similar model of fluctuations in the number of microorganisms in water has been established. The informative value of the method was demonstrated when analyzing transformations in complex systems that do not belong to the category of living: in rivers and reservoirs.","PeriodicalId":305989,"journal":{"name":"Issues of modern algology (Вопросы современной альгологии)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125244845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
