Climatic rainfall regime shapes energy flow, trophic structure, and secondary production in streams.
Article in Ecology, 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
Changes in precipitation patterns linked to climate change have profound implications for the structuring and functioning of riverine ecosystems. This study investigates how rainfall influences secondary production by examining nine rivers across a sharp natural rainfall gradient over 3 years. Utilizing a groundbreaking dataset, we assess community production of both invertebrates and vertebrates, providing one of the most comprehensive multisite and multiyear evaluations of secondary production to date. Our findings reveal that annual rainfall drives significant shifts in productivity and biomass turnover rates. Specifically, we observe a transition from inverted biomass pyramids supported by detritivorous invertebrates in more mesic streams to simplified food webs dominated by vertebrate herbivores in arid environments, where these streams exhibit twice the secondary production and biomass turnover rates. This research underscores the critical role of rainfall as a master variable shaping food web structure and ecosystem productivity. With broad implications for other precipitation-dependent ecosystems, our study offers valuable insights into the future of lotic systems within the context of climate change. Furthermore, our work lays a solid foundation for future investigations into the complex interactions among climate, hydrology, and ecosystem functioning.
