A non-linear effect of the spatial structure of the soil ectomycorrhizal spore bank on the performance of pine seedlings.
Article in Mycorrhiza, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The spatial structure of the environment is known to affect ecological processes. Unlike the spatial structure of negative interactions, such as competition and predation, the role of spatial structure in positive interaction has received less attention. We tested how the spatial structure of spores of ectomycorrhizal fungi (EMF) in the soil affects the growth of Aleppo pine (Pinus halepensis) seedlings. Spores were spatially distributed at four different levels of patchiness (1 patch, 4 patches, 8 patches and complete mixing) in 4 L pots (all pots received the same total amount of spores). Based on previous findings, we hypothesized that plant performance would gradually increase from the single patch treatment to the complete mixing. However, we found a non-linear response to patchiness. Specifically, plants were largest in the single patch and complete mixing while those in the 4 and 8 patch treatments were the smallest. This non-monotonic response, which might be the result of spatially determined colonization timing or community composition, suggests that the spatial structure of EMF spores has a complex effect on seedling growth.
