Distribution patterns of ammonia-oxidizing bacteria and anammox bacteria in the freshwater marsh of Honghe wetland in Northeast China.

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
Community characteristics of aerobic ammonia-oxidizing bacteria (AOB) and anaerobic ammonium-oxidizing (anammox) bacteria in Honghe freshwater marsh, a Ramsar-designated wetland in Northeast China, were analyzed in this study. Samples were collected from surface and low layers of sediments in the Experimental, Buffer, and Core Zones in the reserve. Community structures of AOB were investigated using both 16S rRNA and amoA (encoding for the α-subunit of the ammonia monooxygenase) genes. Majority of both 16S rRNA and amoA gene-PCR amplified sequences obtained from the samples in the three zones affiliated with Nitrosospira, which agreed with other wetland studies. A relatively high richness of β-AOB amoA gene detected in the freshwater marsh might suggest minimal external pressure was experienced, providing a suitable habitat for β-AOB communities. Anammox bacteria communities were assessed using both 16S rRNA and hzo (encoding for hydrazine oxidoreductase) genes. However, PCR amplification of the hzo gene in all samples failed, suggesting that the utilization of hzo biomarker for detecting anammox bacteria in freshwater marsh might have serious limitations. Results with 16S rRNA gene showed that Candidatus Kuenenia was detected in only the Experimental Zone, whereas Ca. Scalindua including different lineages was observed in both the Buffer and Experimental Zones but not the Core Zone. These results indicated that both AOB and anammox bacteria have specific distribution patterns in the ecosystem corresponding to the extent of anthropogenic impact.
