Characteristics of microbial eukaryotic community recovery in eutrophic water by using ecological floating beds.

摘要: Abstract Ecological floating beds can rapidly remove nutrients (nitrogen and phosphorus) from eutrophic water, but we still know little about whether this process simultaneously recover microbial eukaryotic communities. To fill gap, planktonic communities were investigated using 18S rRNA high-throughput gene sequencing during nutrient removal by of Canna indica L. We found that concentrations high in both the control treatment groups period 1 (days 0–5) decreased group 2 6–9) 3 10–18). However, species richness community compositions similar between periods showed small differences 3. The co-occurrence networks also degree centrality interconnected members. some abundant fungi significantly responded to variations, a large number ciliates insensitive removal. Our findings suggest ecological waters it is difficult quickly improve This result reveals critical influence pollution on aquatic ecosystems therefore long-term comprehensive habitat restoration, as macrophyte recoveries should be conducted after controls have been implemented.
