Changing sea ice cover led to marine biodiversity shifts in the Late Quaternary.
Article in Communications earth & environment, 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
Today, the sea ice cover is rapidly declining in the Arctic Ocean. While major changes in the Arctic marine ecosystems are starting to appear, the full implication of a changing Arctic ecosystem is not well understood. Here we show, using sedimentary ancient DNA metabarcoding to document marine eukaryotic communities, that higher diversity is recorded in a warmer, sea ice free Labrador Sea compared to when this region is sea ice covered. Changes in diversity and communities happen slower than the rapid climate warming of Greenland Interstadial 8 (ca. 38,000 years ago) and the Bølling period (ca. 14,700 years ago). Surface ocean conditions, rather than atmospheric warming, exert control on the marine eukaryote community and diversity. Our observations from the paleoclimate record suggest that when sea ice further decreases under global warming, the (sub-)polar marine ecosystems will change drastically, and feedbacks to the carbon cycle and climate system become very likely.
