The diversity and abundance of chytrids on the Greenland Ice Sheet.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Zoosporic fungi of the Chytridiomycota phylum are lethal parasites of algae in Arctic freshwater and marine environments. The presence of members of the Chytridiomycota phylum has also been confirmed by amplicon sequencing and microscopy in various habitats on the Greenland Ice Sheet. Glacier ice algae of the genus Ancylonema (Zygnematophyceae, Streptophyta) dominate microbial communities on the margins of the Greenland Ice Sheet and play key roles in darkening and melting of surface ice. Recent studies and in-situ observations have identified undescribed chytrids infecting Ancylonema spp. blooms on the Greenland Ice Sheet1. In this study, the diversity and abundance of Chytridiomycota fungi were assessed by collection of ice surface and cryoconite holes samples from several locations on the ice sheet. We provide the first quantitative assessment, using qPCR, to reveal that uncultured chytridiomycetous fungi on dark ice were one order of magnitude higher than in cryoconites throughout the 2022 melt season on the Central-West margin of the Greenland Ice Sheet. Phylogenetic trees, based on the assembled environmental 18S rRNA genes, highlight that surface ice habitats dominated by glacier ice algae or snow algae harbor a great diversity of fungi belonging to the Blastocladiomycota, Monoblepharidomycota and Chytridiomycota phyla. They appear to be potential novel taxa, based on small subunit (18S) rRNA gene sequence similarity analysis, increasing our knowledge of chytrids diversity in Arctic environments. The number of novel lineages distinguished from described taxa varied from 63 to 81, based on two sequence identity thresholds (> 97% and > 98%), respectively. Overall, this study addresses the lack of quantitative and phylogenetically resolved information on chytrids in supraglacial environments by providing the first assessment of their abundance and diversity across the Greenland Ice Sheet.
