Phytocenotic organization of algal groups as a possible indicator of the trophic status of bog ecosystems

Abstract

In the soils of bog ecosystems studied in Plesetskii raion of Arkhangelsk oblast, 169 species and infraspecific taxa of algae have been recorded. Their flora includes typical divisions of soil algae and is dominated by Chlorophyta, which is typical for the soil–climatic conditions of the taiga zone in general and bog ecosystems in particular. The phytocenotic organization of algal groups can serve as an indicator of bog trophicity, since a certain trophicity level is characterized by an individual combination of dominant species, life forms, morphotypes, and ecological groups of soil algae.
