Hydropeaking strands and displaces larval and juvenile fish across species.
Article in Communications earth & environment, 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
Hydropeaking, the intermittent operation of hydropower, generates rapid flow fluctuations that disrupt river ecosystems. However, the mechanisms driving stranding and displacement of young fish under varying hydropeaking conditions remain poorly understood. Using a nature-like experimental facility, we conducted ∼1,000 hydropeaking trials involving >120,000 larval and juvenile fish from four species to assess how hydropeaking intensity, environmental conditions, and biotic factors influence fish behavior. Stranding and downstream displacement increased with hydropeaking intensity, particularly at night, in smaller fish, and lower water temperatures. Flow peaks with cold-water releases (thermopeaking) further amplify displacement. Fish demonstrated behavioral adaptation, reducing displacement over successive peaks, suggesting learning effects. The patterns were largely consistent across species. By identifying critical ecological thresholds, our findings inform hydropower strategies that minimize ecological harm while supporting renewable energy production.
