Soil algae in arable land: changes in the genotypic community composition across time points and farming systems—a pilot study

Introduction: , a typical winter cereal under Central European agricultural practices, and examined the effects of contrasting farming systems. Methods: We employed a metabarcoding analysis based on amplicons from multiple markers to assess changes in the genotypic community composition. Results and discussion: , as another crop, significantly increased the ASV richness of Chlorophyceae and Ulvophyceae, whereas that of Cyanobacteria decreased. A large fraction of genotypes, however, remained invariant without response to environmental disturbances; it mainly consisted of Chlorophyta and the Eustigmatophyceae (Stramenopiles).
