Museomics of an extinct European flat oyster population.
Article in Scientific reports, 2025. 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
Understanding the factors that predispose species and populations to decline and extinction is a major challenge of biodiversity research. In the present study, we investigated the historical population genomics of an extinct population of the European oyster (Ostrea edulis L.) from the Wadden Sea collected between 1868 and 1888, and compared it to French and English populations sampled at the same time. Our museomic results indicate that the now-extinct population was genetically isolated from the French and English populations and showed signs of local adaptation in the form of Fst outlier loci between the Wadden Sea and the other two populations. Thus the Wadden Sea oysters may have been predisposed for extinction because they were not naturally replenished from other populations. A comparison of population-wide genomic diversity may hint towards a sudden population contraction of the Wadden Sea population, possibly being the result of stronger - or earlier - population decline in this population than in the others. In summary, our historical population genomic exploration hints at some potential causes of population decline in flat oysters from the Wadden Sea, which might have led to their extinction.
