Competitive interactions during community assembly: how native species identity, diversity, and functional traits affect invasion.
Article in Oecologia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Competitive interactions during community assembly are critical for suppressing invasive species and restoring native biodiversity. However, the roles of plant community attributes in determining competitive suppression remain unclear. We examined the competitive suppression of the invasive perennial herb Solidago altissima L. through a two-year greenhouse experiment. To assess species identity effects, we established pairwise competitions between S. altissima and 19 native species. Diversity effects were evaluated by comparing invasion success in eight four-species native mixtures versus monocultures using relative competition indices (RCI) based on height, cover, density, and biomass. Species identity and functional groups were critical determinants of competitive outcomes. 14 native species significantly suppressed S. altissima growth, with annual herbs (RCI = 0.608-0.771) and perennial herbs (RCI = 0.471-0.666) providing the strongest suppression, while woody perennials were the least effective (RCI = 0.197-0.250). Species diversity showed marginally positive but non-significant effects. Competitive suppression of S. altissima was marginally stronger in mixtures than in monocultures by the second year (mixture RCI = 0.764, monoculture RCI = 0.531, P = 0.084). Functional traits showed inconsistent relationships with competitive outcomes, and trait similarity did not predict invasion suppression. Our results indicate that competitive suppression is primarily driven by species and functional group identities rather than by diversity or trait similarities. Restoration efforts should prioritize fast-growing, canopy-covering non-woody native annuals and perennials-particularly forbs with high specific leaf area, large seed mass, and early canopy dominance-to maximize competitive suppression during community assembly.
