ClearIdentifying Microbial Distribution Drivers of Archaeal Community in Sediments from a Black-Odorous Urban River—A Case Study of the Zhang River Basin
This study investigated how urbanization, eutrophication, and heavy metal pollution shape archaeal (ancient microbial) community composition in sediments of blackened, odorous urban rivers. Understanding microbial responses to these stressors helps track the health of aquatic ecosystems heavily impacted by pollution, including microplastics.
Bacterioplankton Community Structure and Its Relationship with Environmental Factors in the Coastal Waters Around the Changli Gold Coast National Nature Reserve in Northern China
Researchers investigated bacterioplankton community structure in coastal waters around a Chinese nature reserve, finding significant seasonal variability in nutrients and identifying key environmental drivers—including nitrogen, phosphorus, and carbon—of bacterial community composition.
Structure and Assembly Mechanism of Archaeal Communities in Deep Soil Contaminated by Chlorinated Hydrocarbons
Researchers analyzed archaeal community structure and assembly mechanisms in deep unsaturated-zone soil (2–10 m) contaminated with chlorinated hydrocarbons, using high-throughput sequencing to identify key environmental drivers. Contamination significantly altered archaeal composition, with Thermoplasmatota reaching 25.61% relative abundance in heavily polluted soils, and deterministic assembly processes dominating in high-contamination zones alongside 100% positive interspecies collaboration.
Colonization characteristics and dynamic transition of archaea communities on polyethylene and polypropylene microplastics in the sediments of mangrove ecosystems
Researchers found that microplastics in mangrove sediments host distinct communities of archaea (ancient microorganisms) that differ from those in surrounding sediments, with some species linked to increased methane production. The microbial communities on microplastic surfaces shifted over time and showed increased potential for methane emissions and changes in nitrogen cycling. This suggests that microplastic pollution in coastal wetlands could amplify greenhouse gas production and disrupt nutrient cycles that support these critical ecosystems.
Effects of salinity on methane emissions and methanogenic archaeal communities in different habitat of saline-alkali wetlands
This study examined how increasing salinity affects methane emissions and methanogenic microbial communities in saline-alkaline wetlands in the context of climate change. Coastal wetlands are sinks for microplastics as well as important ecosystems for carbon cycling and biodiversity.
The Human Archaeome: Commensals, Opportunists, or Emerging Pathogens?
This review examines the human archaeome—archaeal microorganisms inhabiting the gut, skin, and other body sites—and their potential roles in health and disease. It finds no conclusive archaeal pathogens in humans but identifies indirect roles through metabolic interactions with bacteria, relevant to gut microbiome research.
Marine biofilms: cyanobacteria factories for the global oceans
Researchers re-analyzed 9.3 terabytes of metagenomic datasets and 2,648 metagenome-assembled genomes to reconstruct the diversity and ecology of cyanobacteria in marine biofilms compared to open seawater, finding biofilm cyanobacterial lineage abundances up to 9-fold higher than seawater at equivalent sample sizes. Analysis revealed that biofilm cyanobacteria are ecological specialists with strong geographical and environmental constraints, in contrast to generalistic seawater cyanobacteria, with key diversification events coinciding with major oxygenation events in Earth history.
The Extent and Pattern of Mariculture Impacts on Spatial and Seasonal Variations of Sediment Bacterial Communities Among Three Coastal Waters
Researchers used high-throughput sequencing to examine spatial and seasonal variations in sediment bacterial communities across three Chinese coastal bays with large-scale suspended mariculture, finding that spatial variation was a stronger driver of community composition than seasonality, with Proteobacteria, Bacteroidetes, and Planctomycetes dominating across all sites and mariculture-associated organic loading shaping local community structure.
Large-Scale Integration of Amplicon Data Reveals Massive Diversity within Saprospirales, Mostly Originating from Saline Environments
This paper is not about microplastics — it analyzes global bacterial diversity within the order Saprospirales using environmental DNA databases.
Different Distribution of Core Microbiota in Upper Soil Layer in Two Places of North China Plain
Researchers compared the composition and distribution of core soil microbiota in upper soil layers at two locations on the North China Plain, examining how habitat and dominant plant species shape bacterial community structure relevant to nutrient cycling and carbon storage. The study found meaningful differences in microbial community composition between the two sites, reflecting local environmental influences.
Linear responses of soil microbiomes, metagenomic and metabolomic functioning across ecosystems along water gradients in the Altai region, northwestern China
Researchers analyzed soil microbial communities, their genetic functions, and metabolic profiles across four ecosystems along a water gradient in the Altai region of China. Microbial diversity and carbon and nitrogen cycling functions increased linearly with soil moisture, demonstrating how hydrology shapes ecosystem-level microbial processes.
Community structure and association network of prokaryotic community in surface sediments from the Bering-Chukchi shelf and adjacent sea areas
Prokaryotic community structure and association networks were characterized in surface sediments from 26 stations across the Bering-Chukchi shelf and adjacent northern deep seas. The study revealed how sediment microbial communities reflect both short-term environmental changes and long-term habitat characteristics in one of the world's most productive shelf regions.
Study of the Bacterial, Fungal, and Archaeal Communities Structures near the Bulgarian Antarctic Research Base “St. Kliment Ohridski” on Livingston Island, Antarctica

Microplastic impacts archaeal abundance, microbial communities, and their network connectivity in a Sub-Saharan soil environment
Researchers used 16S rRNA amplicon sequencing to characterise prokaryotic communities in native plastisphere and soil from Sub-Saharan African environments with high unmanaged plastic waste. The plastisphere enriched distinct bacterial communities and archaeal taxa compared to surrounding soil, and high-population sites showed elevated potential pathogen abundance.

Researchers examined soil microbial communities across a forest-to-wetland gradient in China's Lesser Khingan Mountains, comparing mixed forest, conifer forest, wetland edge, and natural wetland. Natural wetland soils harbored the most distinct bacterial communities, driven primarily by high organic matter, nitrogen, and phosphorus content.
Spatiotemporal changes of bacterial communities during a cyanobacterial bloom in a subtropical water source reservoir ecosystem in China
Researchers used DNA sequencing to track how bacterial communities in a Chinese reservoir changed during different phases of a cyanobacterial (harmful algae) bloom, finding that bacterial diversity dropped significantly during the bloom outbreak and that the composition of communities shifted in distinct ways tied to nutrient levels and temperature. Understanding these microbial dynamics could help water managers predict and control harmful algal blooms that threaten drinking water quality.
