From pathogens to partners: temporal and biogeographical patterns in fungal associations of alien trees.
Article in The New phytologist, 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
Alien trees reshape belowground fungal communities, but the factors governing the balance between mutualists and pathogens remain unclear. We tested whether residence time, mycorrhizal type, and biogeographical origin shape this balance, and whether alien stands differ from native vegetation. We sampled soils beneath 73 alien tree species in 48 chateau parks and native stands. Using ITS2 metabarcoding with guild assignment, we quantified ectomycorrhizal (ECM) and pathogen fungi and analysed predictors with multivariate models and binomial GLMMs, accounting for spatial structure and covariates. Symbiotic fungal community composition varied with origin, phylogenetic group and mycorrhizal type. With increasing residence time, ECM alien trees showed higher ECM fungal richness and relative abundance; whereas, contrary to enemy accumulation expectations, pathogen richness and relative abundance declined. Alien arbuscular mycorrhizal (AM) trees harboured more pathogens than ECM trees. Alien tree assemblages had a lower ECM fungal share, twice the pathogen relative richness, and threefold higher pathogen relative abundance than native assemblages. Residence time and mycorrhizal type are primary filters shaping belowground trajectories of alien trees, with biogeographical origin patterning community composition. Elevated pathogen loads in alien stands highlight spillover risks to neighbouring vegetation, informing risk assessment and monitoring of alien tree plantings.
