Spatial Heterogeneity of Microbial Communities and Biogeochemical Function in Water Column of Site F Cold Seep, South China Sea.
Article in Microbial ecology, 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
Cold seep is a distinctive deep-sea environment mainly formed by methane-rich fluids leaking on the seafloor, gaps remain regarding the influence of seepage on microorganisms inhabiting water column across vertical and horizontal dimensions. Site F cold seep, located at 1,120 m depth on the northern South China Sea (SCS) slope, is one of the most active cold seeps in SCS. We performed 16S rRNA gene and metagenomic sequencing on samples collected by Niskin bottles mounted on Conductivity-Temperature-Depth profiler and Remote Operated Vehicle to analyze the structure and metabolic potentials of microbial communities throughout the water column at Site F. Microbial abundance generally decreased with depth at all sampling spots and was higher at sites adjacent to the seepage compared to those farther away, indicating a potential vertical and horizonal influence of methane seepage on water microbial community. High microbial abundance at deeper depths may attribute to a higher proportion of Gammaproteobacteria, comprised mainly of Alcanivoracaceae, Alteromonadaceae, Marinobacteraceae, methylotrophs represented by Methylophagaceae and Methylococcales (mainly Methylomonadaceae), and sulfur-oxidizing bacteria represented by SUP05 and Ectothiorhodospiraceae. Consistently, the aerobic methane oxidation gene pmoA was more prevalent in the deeper water and was found in four bacterial classes in addition to Gammaproteobacteria. Sulfur-oxidizing genes also exhibited higher abundances at depths and were primarily affiliated with Rhodobacteraceae. These microbes likely play important roles in aerobic oxidation of methane and sulfur, contributing to methane depletion during upward diffusion. By integrating sampling across vertical and horizontal dimensions, we demonstrate that seepage shapes the microbial community and biogeochemical functions in the water column at Site F.
