Temporal Decoupling of Biodiversity Effects on Grassland Productivity and Stability.
Article in Ecology letters, 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
One key unresolved question in ecology is what drives temporal trends in biodiversity-stability relationships and how these trends link to ecosystem functioning. This knowledge gap reflects a limited understanding of interspecific interactions in biodiversity-stability relationships. Using plant productivity data from a 20-year grassland biodiversity experiment, complemented by a paired 5-year experiment that controlled for legacy effects, we disentangled the contributions of species-specific dynamics and interaction-dependent processes to plant community stability. Over 20 years, the stabilising effects of biodiversity strengthened, driven mainly by increasing asynchrony in species-specific dynamics rather than shifts in interaction-dependent effects. While biodiversity's stabilising effect initially increased alongside productivity, this coupling weakened over time as interaction-dependent effects on productivity and stability became decoupled. Our findings reveal the dynamic nature of biodiversity effects on plant community stability, underscoring the importance of understanding long-term ecosystem trajectories.
