Soil algae in arable land: changes in the genotypic community composition across time points and farming systems-a pilot study.
Article in Frontiers in microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Soil algae, including Cyanobacteria, in the topsoils of arable land are essential for many valuable effects on soil texture and fertility. However, the constant changes and disturbances caused by agricultural practices create a challenging environment. We tested for responses in soil algal diversity across principal time points during the growth of Methods: We employed a metabarcoding analysis based on amplicons from multiple markers to assess changes in the genotypic community composition. Results and discussion: Relationships among the detected key groups of soil algae, i.e., Chlorophyta (Chlorophyceae, Trebouxiophyceae), Stramenopiles (Xanthophyceae, Diatomeae), and Cyanobacteria, varied significantly across the three principal time points of the wheat's growth season. The eukaryotic algae (118 genera) alone accounted for approximately one-third in March to approximately one-half in July of all microeukaryote ASVs in the surface soils. The 23S UPA marker, used to amplify eukaryotic algae and Cyanobacteria in a single step, and the 18S marker differed in their estimates of ASV numbers for Chlorophyta and Xanthophyceae. However, in combination with markers specifically targeting the green algal ITS2 and the
