Spatial self-segregation of pioneer cyanobacterial species drives microbiome organization in biocrusts.
Article in ISME communications, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
Microbial communities are typically characterized by some degree of self-organization. In biological soil crust (biocrust) communities, vertical organization of resident populations at the mm scale is driven by organismal adaptations to physicochemical microniches. However, the extent of horizontal organization and its driving processes are unknown. Using a combination of observational and genetic mapping, we provide evidence for a highly defined, horizontal self-organization (patchiness) at the mm to cm scale in a successionally early biocrust community dominated by the pioneer cyanobacteria, Microcoleus vaginatus (Microcoleaceae) and Parifilum sp. (Coleofasciculaceae). Experiments with representative isolates of each species demonstrate that the phenomenon is driven by active spatial segregation based on cross-species sensing through the exometabolome acted upon with motility responses. Further, we show that both species share the ability to enrich for specialized cyanospheres of heterotrophic bacteria at smaller scales, and that these cyanospheres are characterized by compositional host-specificity, thus expanding the reach of spatial patchiness beyond primary producers. Our results highlight the importance of specific microbial interactions in the emergence of microbiome compositional architecture and the enhancement of microbial diversity.
