Temporal dynamics of the fecal microbiome in wintering seagulls: a One Health perspective.
Article in BMC genomics, 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
backgroundMigratory birds serve as critical reservoirs for zoonotic pathogens, with transmission risks significantly amplified by anthropogenic activities such as recreational feeding. Despite their role in disseminating pathogens, the temporal dynamics of the gut microbiota in wintering seagulls under sustained human contact remain poorly characterized within a One Health framework.
resultsIn this study, we conducted semi-monthly fecal sampling of black-headed gulls overwintering at a coastal tourism hotspot during consecutive wintering periods. Full-length 16S rRNA PacBio HiFi sequencing revealed remarkable microbial diversity and skewed distributions within the fecal communities. Although stochastic processes dominated microbial community assembly, temporal dynamics were observed as significant fluctuations in diversity indices, shifts in taxa prevalence, and episodic blooms of specific bacteria, reflecting signatures of foraging activities and anthropogenic interventions, particularly the provision of supplemental human food. Notably, 53 putative species-level pathogens were identified, with 11 of these exhibiting potential for cross-host transmission between migratory gulls and local inhabitants.
conclusionsOverall, this study provides a comprehensive One Health perspective on the gut microbiome of wintering migratory seagulls, offering valuable reference information for future wildlife management and public health protection.
