Effects of different types of anthropogenic disturbances and natural wetlands on water quality and microbial communities in a typical black-odor river

Ecological Indicators, Journal Year: 2022, Volume and Issue: 136, P. 108613 - 108613

Published: Feb. 1, 2022

Natural rivers have always been invaded by multiple pollutants discharged anthropogenic activities, inducing physiochemical and biological changes to waterbodies. However, the effects of different types disturbances natural wetlands on water quality bacterial communities in black-odor remain largely unknown. In this study, 13 parameters at 48 sampling sites along typical contaminated Jishan River were selected evaluate through index (WQI). The analysis microbial community composition its correlation with (industrial effluent, aquacultural wastewater, domestic sewage, confluences, dam wetlands) further conducted. results revealed that had significant spatial heterogeneity samples disturbed sites, shaped abundance distribution communities. Among these disturbances, altered hydrological hydraulic conditions river, leading worst quality, fermentative microorganism Lactococcus becoming dominant genus. surrounding terminus river recuperative functions could restore community. WQI values 38.08–63.46 rated as "low" or "moderate" primarily affected excessive nutrient contaminates, such nitrogen, phosphorus, organic matter.

This study not only facilitated a more comprehensive understanding about between ecosystem but also provided theoretical support ecological restoration governmental regulation ecosystem.

Global assembly of microbial communities

mSystems, Journal Year: 2023, Volume and Issue: 8(3)

Published: May 17, 2023

Different habitats harbor different microbial communities with elusive assembly mechanisms. This study comprehensively investigated the global mechanisms of and effects community-internal influencing factors using Earth Microbiome Project (EMP) data set. We found that deterministic stochastic processes contribute approximately equally to community assembly, and, specifically, generally play a major role in free-living plant-associated (but not plant corpus) environments, while are contributor animal-associated environments. In contrast microorganisms, functional genes, predicted from PICRUSt, is mainly attributed all communities. The sink source normally assembled similar mechanisms, core microorganisms specific environment types. On scale, positively related alpha diversity, interaction degree bacterial predatory-specific gene abundance. Our analysis provides panoramic picture regularities environment-typical assemblies. IMPORTANCE With development sequencing technologies, research topic ecology has evolved composition including relative contribution for formation maintenance diversity. Many studies have reported various habitats, but remain unknown. this study, we analyzed EMP set combined pipeline explore communities, sources construct microbes types, assembly. results provide rules assemblies, which enhances our understandings globally controlling diversity species coexistence.
