The influence of active metabolites from the decomposition of camelina and barley straw on the development of phytoplankton from eutrophic freshwater ecosystem.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
As a result of human activities, surface waters worldwide are experiencing increasing levels of eutrophication, leading to more frequent occurrences of microalgae, including harmful algal blooms. We aimed to investigate the impact of decomposing camelina straw on mixed phytoplankton communities from eutrophic water bodies, comparing it to the effects of barley straw. The research was carried out in 15 aquaria (five of each type - containing no straw, camelina straw, and barley straw). The experiment lasted eight weeks, and the water used in the aquaria was sourced from an eutrophic reservoir. Our research revealed that the camelina straw had the most significant inhibitory effect on the growth of specific groups and species of phytoplankton (especially chrysophytes, potentially toxic cyanobacteria, and dinoflagellates). This inhibition was achieved by releasing polyphenols, primarily gallic and caffeic acids and flavonoids. Simultaneously, polyphenols promoted the growth of filamentous green algae. Our findings present novel data on the vulnerability of freshwater species and taxonomic groups of algae to the effects of camelina and barley straw exposure.
