Multitrophic biodiversity drives soil phosphorus mobilization in subtropical ecosystems.

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
introductionThe phosphorus (P) mobilization capacity of plants and microbes is hierarchically constrained by climatic drivers, land-use types, lithological properties, and consumer-mediated trophic cascades. OBJECTIVES AND
methodsWe established a latitudinal transect across contrasting lithologies (carbonate vs. siliciclastic sedimentary rocks) in subtropical southwest China to investigate how multitrophic biodiversity and trophic interactions affect soil P mobilization during cropland-to-forest succession.
resultsCropland conversion into forest significantly increased soil labile P fractions by 43.8% in karst regions, but decreased soil moderately labile and stable P fractions by 62.6-79.1% and 34.8-36.6%, respectively, in both karst and non-karst regions. Multitrophic biodiversity and P mobilization capacity were significantly greater in karst than non-karst regions. Climate warming amplified trophic cascading effects on soil P mobilization capacity mediated by phoD-harboring bacteria in forests via increasing alkaline phosphatase activity. Karst forests developed efficient P mobilization-uptake coordination to overcome calcium/magnesium-induced P chelation constraints through tightly coupled multitrophic interactions. The multitrophic network relationships are conducive to plant P uptake, but vulnerable to species losses caused by anthropogenic disturbances (e.g., tillage and deforestation) in karst ecosystems.
conclusionOur findings provide a framework linking lithology-mediated P mobilization with trophic interactions to alleviate P limitation in subtropical ecosystems under global change.
