Gut-microbiome composition, single nucleotide polymorphisms, and differentially expressed genes correlate with aggression in an ant.
Article in iScience, 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
Animals frequently display aggressive behavior, for example, when competing for food. Aggression is influenced by various extrinsic and intrinsic factors such as the microbiome and genetics. However, we currently lack understanding what factors cause animals to start aggression. Here, we use an ant species to test if chemical, microbiome, genomic, and/or transcriptomic traits correlate with the start of aggression and the reactions to it, namely reacting aggressively or peacefully. We found nine bacterial operational taxonomic units, mutations in two genes, and eight differentially expressed genes, which were positively or negatively associated with the start of aggression or reactions to it. The microbiome and genetic factors are mainly linked to hormone signaling and neurological and synaptic functions, respectively. The results indicate that multiple traits, possibly acting in concert, may affect the start of aggression and reactions to it. We speculate that such traits could promote aggression and play important evolutionary roles.
