“…Contrary to the richness, Shannon's diversity index is much less sensitive to sequencing and PCR errors (Kunin et al, 2010;Wu et al, 2010;Zinger et al, 2011). The Shannon indices of the three types of sediments determined in the present study (6.3 to 6.9) were comparable with those recently reported using pyrosequencing methods, even though different methodologies were employed (Thijs et al, 2017;Iliev et al, 2019;Wang et al, 2020).…”

“…Wetlands are recognized as a hot spot for studying microbial diversity and their role in ecology. However, research investigating microbial communities in different types of wetlands has seldom been reported (Gutknecht et al, 2006;Iliev et al, 2019;Wang et al, 2020). The microbial richness, evenness, and diversity are very important early indicators to predict the possible variation in community composition and the systems functionalities (Santos et al, 2019).…”

The ultimate role of prokaryote (bacteria and archaea), the decomposer of the wetland ecosystem, depends on its community structure and its interaction with the environment. The present study has used three universal prokaryote primers to compare prokaryote community structure and diversity of three distinctly different wetlands. The study results revealed that α-diversity indices and phylogenetic differential abundance patterns did not differ significantly among primers, but they did differ significantly across wetlands. Microbial community composition revealed a distinct pattern for each primer in each wetland. Overall comparison of prokaryote communities in sediments of three wetlands revealed the highest prokaryote richness and diversity in Bhomra (freshwater wetland) followed by Malencho (brackish-water wetland) and East Kolkata wetland (EKW) (sewage-fed wetland). Indicator genus analysis identified 21, 4, and 29 unique indicator genera, having preferential abode for Bhomra, EKW, and Malencho, respectively. Prediction of potential roles of these microbes revealed a preference for sulfate-reducing microbes in Malencho and methanogens in Bhomra. The distinct phylogenetic differential abundance pattern, microbial abode preference, and their potential functional role predict ecosystem variables shaping microbial diversity. The variation in community composition of prokaryotes in response to ecosystem variables can serve as the most sensitive bioindicator of wetland ecosystem assessment and management.

The impact of A. palmeri invasion on soil bacterial community under different habitats is unclear. In this work, the influence of A. palmeri invasion on soil bacterial diversity and community structure were investigated using full-length 16S rRNA sequencing technology under four typical habitats of riverbank (A), roadside (B), wasteland (C) and farmland (D). A two-way ANOVA analysis showed that habitat, invasion and the interaction of them had little effect on alpha diversity, expect for habitat factor had a significant effect on Simpson indices (P<0.05). NMDS analysis demonstrated that soil bacterial community structures among different invasive habitats were clearly distinguished. In addition, the most abundant phyla in the non-invasive plots were Proteobacteria, Planctomycetes and Gemmatimonadetes. However, the third predominant phyla converted from Bacteroidetes to Gemmatimonadetes with the invasion of A. palmeri. LEfSe analysis revealed that the core microbiome, Burkholderiaceae and Betaproteobacteriales (riverbank habitat), Gemmatimonadetes and Gemmatimonadaceae (wasteland habitat), Sphingomonas_sediminicola (roadside habitat), Nitrosomonadaceae (farmland habitat), which played important roles in facilitating the establishment of A. palmeri to heterogeneous habitats.

“…Chen et al (2020) also found that the changes in the fungal community composition were significantly correlated with the soil properties, particularly the available Zn. The contents of metal nutrients (Ca, K, and Fe) had positive correlations with the fungal community structure in the soils affected by coal mine exploitation (Wang et al 2020). This may be due to the fact that the evolution of these fungal communities was easily driven by external input, and thus, it is necessary to explore the major factors affecting the fungal community in human excrement after household toilet treatment, which is beneficial to the regulation of the fungal community in farmland soil after application.…”

Recent studies on the microbial community composition of human excrement after rural household toilet treatment are unclear regarding the effects and risks of using recycled products as fertilizers in agriculture. In this study, we used Illumina high-throughput sequencing to investigate the microbial community structure of the excrement from 50 Chinese rural household toilets on a spatial scale, and we evaluated the impact of select geochemical factors on the bacterial and fungal communities in the human excrement. Multivariate analysis showed that there was a significant spatial differentiation of the human excrement in microbial communities after all toilet treatments. Twenty dry toilet samples and thirty septic tank samples had similar bacterial (Firmicutes, Proteobacteria, Actinobacteria, and Bacteroidetes) and fungal phyla (Ascomycota and Basidiomycota), differing only in the proportions of the microorganisms. For both dry toilet samples and septic tank samples, the pH and ammonium nitrogen were found to be the major driving forces affecting the changes in bacterial community structures ( p <0.05), while there was no correlation found for the fungal community with environmental factors in China ( p >0.05), except in the northern regions, where the total phosphorus was found to be significantly correlated with the fungal community ( p <0.05). Network analysis confirmed that NH 4 + -N had the most significant impact on the content of pathogens. Certain pathogens were still detected after toilet treatment, such as Streptococcus , Bacteroides , Aspergillus , and Chrysosporium , and the proportion of potential pathogenic bacteria in dry toilets was higher than that in septic tanks, suggesting that septic tanks were better than dry toilets in treating human excrement. These results provide an ecological perspective for understanding the large-scale geographic distribution of household excrement microbial communities in rural areas and for improving human excrement treatment technologies and avoiding the risks of agricultural applications.
