Таксономическая и экологическая структура водорослевых сообществ дерново-подзолистой оптимизированной песчаной почвы [Articol]

Abstract

The term “soil algae” usually refers to a combination of several groups of algae,including water and terrestial algae. Soil algae in Belarus are little studied group of organisms, and to date this group of algae (especially algal flora of agricultural soils) is largely unexplored. In our studies six divisions of soil algae have been identified: Cyanophyta – 17 species (40.5% of total number), Bacillariophyta – 5 (11.9%), Xanthophyta – 4 (9.5%), Euglenophyta – 1 (2.4%) , Chlorophyta – 14 (33.3%), and Rhodophyta – 1 species (2.4%). There were calculated the indices of life forms to assess the structure of the algal flora in optimized soil. Most representatives were typical soil algae, the hydrophilic part of algae community in the studied sites was rather small, amfibian algae were not found during our study.
