Low shifts in salinity determined assembly processes and network stability of microeukaryotic plankton communities in a subtropical urban reservoir

Microbiome, Journal Year: 2021, Volume and Issue: 9(1)

Published: June 3, 2021

Abstract Background Freshwater salinization may result in significant changes of microbial community composition and diversity, with implications for ecosystem processes function. Earlier research has revealed the importance large shifts salinity on physiology ecology, whereas studies effects smaller or narrower microeukaryotic inland waters are scarce. Our aim was to unveil assembly mechanisms stability plankton networks at low salinity. Results Here, we analyzed a high-resolution time series data from an urban reservoir subtropical China over 13 consecutive months following one periodic change ranging 0 6.1‰. We found that (1) increase altered led decrease (2) influenced primarily by regulating deterministic-stochastic balance, deterministic becoming more important increased salinity, (3) core subnetwork robustness higher low-salinity levels, while satellite subnetworks had greater medium-/high-salinity levels. results suggest influence rather than successional time, is driving force shaping dynamics. Conclusions findings demonstrate salinities, even small increases sufficient exert selective pressure reduce diversity alter mechanism network stability. provide new insights into ecology impacts microbiotas architecture.

Spatiotemporal dynamics of the archaeal community in coastal sediments: assembly process and co-occurrence relationship

The ISME Journal, Journal Year: 2020, Volume and Issue: 14(6), P. 1463 - 1478

Published: March 4, 2020

Studies of marine benthic archaeal communities are updating our view their taxonomic composition and metabolic versatility. However, large knowledge gaps remain with regard to community assembly processes inter taxa associations. Here, using 16S rRNA gene amplicon sequencing qPCR, we investigated the spatiotemporal dynamics, processes, co-occurrence relationships in 58 surface sediment samples collected both summer winter from across ~1500 km eastern Chinese marginal seas. Clear patterns dynamics structure were observed, a more pronounced spatial rather than seasonal variation. Accompanying geographic variation was significant distance-decay pattern varying contributions different clades, determined by relative abundance. In seasons, dispersal limitation most important process, explaining ~40% variation, followed homogeneous selection ecological drift, that made an approximately equal contribution (~30%). This meant stochasticity determinism had greater impact on assembly. Furthermore, observed seasonality patterns: closer inter-taxa connections summer, unmatched between relationship. These results demonstrate assembled under seasonal-consistent mechanism but changed over indicating complex dynamic coastal sediments

Archaeal and bacterial communities assembly and co-occurrence networks in subtropical mangrove sediments under Spartina alterniflora invasion

Environmental Microbiome, Journal Year: 2021, Volume and Issue: 16(1)

Published: May 3, 2021

Abstract Background Mangrove ecosystems are vulnerable due to the exotic Spartina alterniflora ( S. ) invasion in China. However, little is known about mangrove sediment microbial community assembly processes and interactions under invasion. Here, we investigated co-occurrence networks of archaeal bacterial communities along coastlines Fujian province, southeast Results Assembly overall was driven predominantly by stochastic processes, relative role stochasticity stronger for bacteria than archaea. Co-occurrence network analyses showed that structure more complex The keystone taxa often had low abundances (conditionally rare taxa), suggesting abundance may significantly contribute stability. Moreover, increased drift process (part processes), improved complexity stability, but decreased stability bacteria. This could be attributed influenced diversity dispersal ability, as well soil environmental conditions. Conclusions study fills a gap patterns both archaea ecosystem Thereby provides new insights plant on biogeographic distribution patterns.
