ABSTRACT

The new class Bracteacocco-Hantzschietea is described; this class unites algal communities (algocenoses) of urbanized ecosystems and adjacent areas. Widespread ubiquitous species prevail in the floristic composition of algal communities of the class. Zonal peculiarities are evident at the level of orders Cylindrospermetalia licheniformis and Phormidio-Oscillatorietalia representing communities of the forest and steppe zones. Convergence of the floristic structure of two regional floras of settlements of different climatic zones occurred as a result of synanthropization due to penetration of species of anthropically disturbed habitats. In the forest zone the algal communities were characterized by a more mosaic structure under the influence of microrelief, the herbaceous and moss cover, and trees and shrubs. In steppe and meadow communities the conditions for occurrence of algae are more uniform and, hence, the diagnostic areas of algal cenoses are larger.
