Impact of Temperature, Nutrients and Heavy Metals on Bacterial Diversity and Ecosystem Functioning Studied by Freshwater Microcosms and High-Throughput DNA Sequencing.

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
Microbial communities are fundamental components in freshwater, and community shifts in ecosystem structure are indicative of changing environmental conditions. This study aimed at investigating the influence of key environmental parameters on bacterial diversity and ecosystem functioning (i.e. organic matter breakdown) in laboratory freshwater microcosms. The effects of varying temperatures (5, 20 and 35 °C), nutrients (representing low, medium and high urbanization) and heavy metals Copper (Cu) and Zinc (Zn) on bacterial diversity and organic matter (OM) breakdown were studied by using leaf bags and capsules filled with polycaprolactonediol-2000 (PCP-2000), respectively. The leaf-associated bacterial diversity was determined by next-generation sequencing of SSU rRNA gene amplicons. The results showed that bacterial diversity increased at high temperature (35 °C) with more operational taxonomic units (OTUs) as compared to medium (20 °C) or low (5 °C) temperatures, whereas nutrient variation had fewer effects on the bacterial community structure. In contrast, the presence of heavy metals, especially high concentrations (100 μM) of Cu, reduced the number of OTUs in the leaf-associated bacterial community. The higher temperatures and nutrient levels accelerated PCP-2000 breakdown rate, but this was impeded by a high concentration (100 μM) of Cu in the short term, though no effect of Zn on breakdown rate was observed. The overall results indicate that temperature and variated heavy metals are among the key factors that affect bacterial diversity and ecosystem functioning in freshwater systems.
