1 · What the graph read from it

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.

2 · The registry

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

Subtropical forests are vital to global carbon pools, and their responses to increasing warming may significantly influence carbon sequestration. However, how subtropical tree species adjust the photosynthesis and respiration process in response to climatic warming through phenotypic plasticity is still unclear which is critical for predicting future forest carbon dynamics. A two-year warming experiment was conducted using open-top chambers (OTCs) in a subtropical forest in South China, increasing ambient temperature by approximately 1.5 ± 0.5 °C. Measurements included photosynthetic rate, stomatal conductance, chlorophyll fluorescence (Fv/Fm), night respiration, predawn and midday water potential, and key leaf structural traits across ten individuals of Schima superba, Ormosia pinnata, Pinus massoniana, and Castanopsis hystrix. Schima superba, Ormosia pinnata, and Pinus massoniana exhibited increased photosynthesis, stomatal conductance, leaf area, and biomass under warming, indicating strong physiological plasticity. In contrast, Castanopsis hystrix showed reduced gas exchange, growth, and stomatal traits because it may lack adaptive traits critical for warming resilience, indicating a divergent response to the same environmental condition. All species exhibited reduced PSII efficiency (Fv/Fm) and more negative water potentials under warming. Several structural traits, including stomatal density and specific leaf area, were positively correlated with improved physiological performance. Subtropical tree species exhibit distinct thermal response strategies, with some benefiting from modest warming and others displaying signs of stress. Species with high physiological plasticity may better maintain function and productivity under warming. These findings highlight the importance of accounting for species-specific traits in predicting forest responses to climate change and inform forest management under future warming scenarios.
