Catch up on your reading of late 19th-century trends through these historical pages. A heatmap was produced in R project R As the third domain of life, archaea was once considered as significant habitant of extreme environments, but increasing evidence reveals their widespread presence in various nonextreme environments, including soil, ocean, and freshwaters [ 1 ]. MCG-1, Methanomicrobiales, and Methanosarcinales all have a wide habitat in various water environments.
Compared to bacteria, the diversity and community distribution of sediment archaea have received much less attention in freshwater lake environments. Local conditions structure unique archaeal communities in the anoxic sediments of meromictic Lake Kivu. Based on the heatmap analysis of archaea community on order level affiliation, all sampling sites could be divided into three groups: The “Daily Chicago Tribune” became a leading anti-slavery newspaper when Joseph Medill took the helm in Author information Article notes Copyright and License information Disclaimer.
The coordinates and water depth of these selected sampling sites are shown in Table 1. Pearson’s correlation coefficients were used to investigate the correlations between the lake sediment properties and the archaea communities Table 4. Therefore, information on the microbial community composition is of vital importance for better understanding of the metabolic processes in aquatic ecosystems.
The low content of Pb in sites NP and GJ may be also due to the presence of Halobacteriales, which had the capacity to reduce the concentration of Pb, Cr, Zn, and Ni ions from media with high salinity [ 60 ]. The authors declare that there is no conflict of interests regarding the publication of this paper.
The salinity played an important role in controlling diversity and distribution of archaea in estuarine sediments [ 1415 ], particle gbi and water O 2 saturation also shaped the sediment archaea distribution [ 16 ]. Standards Press of China; Chinese. Effects of heavy metal and nutrients on benthic microbial communities in freshwater sediment of Poyang Lake China Journal of Residuals Science and Technology.
The community structure of sediment archaea could be influenced by pollution [ 58 ], sediment depth [ 34 hgi, 53 ], and salinity [ 59 7551-1. Biodiversity changes in the lakes of the Central Yangtze. The inflow river has made bi important contribution to the eutrophication and contamination of Poyang Lake; among the five tributaries, Gan, Xin, and Rao Rivers were polluted by industrial plants discharges copper and phosphate mines in the upstream of Rao and Xin Rivers and urban wastes Nanchang City in the upstream of Gan River [ 20 ].
This study was the primary attempt to unscramble the total archaea community in the Poyang Lake sediment. Similar to previous reports, the most frequently found archaea of this study was composed of Bathyarchaeota MCGThaumarchaeota, Methanosarcinales, Methanomicrobiales, Methanobacteriales, and Thermoplasmatales [ 31 ].
Archaea community is less influenced by hgi factors compared with bacteria [ 13 ]; several parameters are found to affect the distribution of archaea in lake sediments. Water depth may influence the precipitation process of sediment and affected many sediment parameters [ 3453 ], while the pressure of Pb selected special archaea groups and reduced the evenness.
big Materials and Methods 2. The contents of TOC and Pb could shape the distribution pattern of archaea community among different sites of Poyang Lake.

Influential Factors on Archaea Communities Pearson’s correlation hgi were used to investigate the correlations between the lake sediment properties and the archaea communities Table 4. Bathyarchaeota was believed to have an organic heterotrophic lifestyle and can degrade buried organic carbon and detrital proteins in subsurface sediments [ 3637 ].
Few previous studies indicated the variation of archaea community structure and diversity with several factors, such as sediment depth, sampling sites, and contamination [ 10 — 12 ]. The objective of the present study is to characterize the archaea community structure in sediments of Poyang Lake and estimate the influence of surface sediment properties on the spatial distribution of archaea community.

The new genome reading of Thermoplasmatales cells has revealed the genes that encode extracellular protein-degrading enzymes and which could enable them vgi survive on sedimentary detrital proteins [ 37 ].
