Abstract

Microorganisms typically form diverse communities of interacting species, whose activities have tremendous impact on the plants, animals and humans they associate with. The ability to predict the structure of these complex communities is crucial to understanding and managing them. Here, we propose a simple, qualitative assembly rule that predicts community structure from the outcomes of competitions between small sets of species, and experimentally assess its predictive power using synthetic microbial communities composed of up to eight soil bacterial species. Nearly all competitions resulted in a unique, stable community, whose composition was independent of the initial species fractions. Survival in three-species competitions was predicted by the pairwise outcomes with an accuracy of ~90%. Obtaining a similar level of accuracy in competitions between sets of seven or all eight species required incorporating additional information regarding the outcomes of the three-species competitions. Our results demonstrate experimentally the ability of a simple bottom-up approach to predict community structure. Such an approach is key for anticipating the response of communities to changing environments, designing interventions to steer existing communities to more desirable states and, ultimately, rationally designing communities de novo.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In prokaryotes, intercellular communication and multicellular coordination are widespread and influence the expression and intensity of multiple phenotypes.

    “In procaryotes, intercellular communication and multicellular coordination are widespread and influence the expression and intensity of multiple phenotypes [6,8,9,10,11,12].”

    From Microbiota of Cheese Ecosystems: A Perspective on Cheesemaking (2025) · cites this paper as [12]

    The Main text discusses competition, coexistence, and community structure among microbial species, but does not address whether intercellular communication or multicellular coordination is widespread in prokaryotes or regulates phenotypes. Searches for those concepts and for quorum sensing found no passage supporting the attributed claim. (LLM, conf=0.74)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
