Shcherbyna V. Ecological peculiarities of algogroups of virgin and anthropogenically disturbed steppes of the Southern Steppe of Ukraine.

The object is the ecological peculiarities of algogroups of virgin and anthropogenically disturbed steppes of the Southern Steppe of Ukraine. The aim is to study the ecological peculiarities of algogroups of virgin and anthropogenically disturbed steppes of the Southern Steppe of Ukraine and their bioindicative opportunities. The methods are conventional methods for sampling soil algological samples, methods of analysis of the structural and functional organization algogroups, floral, physical and chemical soil analysis, statistical. The features of the distribution of algae in the soil profile of virgin and anthropogenically disturbed steppe biogeocenosis are defined. The nature of seasonal changes at the level of species composition, life forms, dominant, taxonomic structure, abundance and biomass of algae and their transformations under the influence of a variety of anthropogenic influences are determined. It is found that the taxonomic and ecological diversity algogroups affect environment-transforming phytocenosis factors and physical and chemical parameters of soil granulometric composition, humus content, pH. Application spheres are training courses and algoindication.
