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

Mixed-species plantations have been increasingly promoted as a strategy to enhance ecosystem functioning and related ecosystem processes; however, their global impacts on biomass production and nutrient cycling remain uncertain. Here we present a comprehensive meta-analysis based on a random-effects model of 8,450 paired observations from 328 studies spanning diverse climatic zones, stand structures, and silvicultural systems. We demonstrate that species mixing significantly enhances plant biomass and nutrient content compared to monocultures, with positive responses observed across trees, shrubs, litterfall, and both above- and belowground compartments. Mixed-species plantations also increase soil organic carbon, total nitrogen, phosphorus availability, microbial biomass, and leaf nutrient content while maintaining stable soil stoichiometric ratios, collectively reflecting more efficient stand-level nutrient cycling. Importantly, the magnitude of these effects was shaped by climatic and structural contexts, with stronger positive outcomes under warmer and wetter climates, increasing with species richness, and showing unimodal responses to elevation, stand age, and stand density. By synthesizing multi-scale evidence from diverse ecosystems, we reveal that species mixing promotes biomass accumulation, improves nutrient retention, and strengthens biodiversity-nutrient cycling linkages. This study highlights the potential of mixed-species plantations to enhance ecological function, advance forest restoration, and guide plantation management across diverse environmental conditions.
