ClearDifferent 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.
Soil Microbial Communities in Pseudotsuga sinensis Forests with Different Degrees of Rocky Desertification in the Karst Region, Southwest China
Researchers studied how increasing levels of rocky desertification in karst forests in southwest China affect soil microbial communities. They found that bacterial diversity declined significantly as desertification worsened, while fungal communities showed more resilience. Key soil properties including pH, organic carbon, and available nitrogen were identified as the main drivers shaping these microbial community shifts.
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.
Effects of Polycyclic Aromatic Hydrocarbons on the Composition of the Soil Bacterial Communities in the Tidal Flat Wetlands of the Yellow River Delta of China
Researchers found that polycyclic aromatic hydrocarbons (PAHs) significantly altered soil bacterial communities in tidal flat wetlands of China's Yellow River Delta. The study suggests PAH contamination reduces bacterial diversity while shifting the relative abundance of key bacterial phyla, with soil properties like nitrogen, carbon, and phosphorus playing important roles in shaping microbial community responses.
Ecological differentiation and assembly processes of abundant and rare bacterial subcommunities in karst groundwater
Researchers examined ecological differentiation between abundant and rare bacterial communities in karst groundwater in southwest China, revealing distinct assembly processes and environmental drivers that maintain ecosystem stability in these vulnerable aquifers.
Soil horizons regulate bacterial community structure and functions in Dabie Mountain of the East China
This paper is not relevant to microplastics research — it examines how soil horizon depth influences bacterial community structure and nutrient cycling functions in mountain forest soils.
Anthropogenic land uses shape denitrification-related microbial communities in freshwater river ecosystems
Researchers investigated how anthropogenic land uses (agricultural and urbanized) versus natural land uses shape denitrification-related microbial communities in the Weihe and Hanjiang Rivers in China's Qinling Mountains using deep 16S rRNA gene sequencing of water and sediment samples. Results revealed that land-use type significantly alters the composition and function of nitrogen-cycling microbial communities in freshwater river ecosystems.
Collaborative Changes between Soil Fauna and Urbanization Gradients in Guangzhou’s Remnant Forests
Researchers investigated how soil fauna communities change along urbanization gradients in Guangzhou, finding that urbanization significantly reduces soil biodiversity and alters functional group composition, with implications for ecosystem services.
Types of vegetables shape composition, diversity, and co-occurrence networks of soil bacteria and fungi in karst areas of southwest China
Researchers examined how different vegetable crops influence the composition of soil bacteria and fungi in karst landscapes of southwest China. They found that the type of vegetable grown significantly shaped the diversity and co-occurrence patterns of soil microbial communities. The findings provide a foundation for understanding how agricultural practices affect soil health in ecologically fragile karst environments.
Contrasting the diversity patterns and processes of microbial community assembly in water and sediment in Lake Wuchang, China
This study investigated how bacterial communities are distributed between water and sediment in Lake Wuchang, China, finding that different ecological processes drive community assembly in each habitat. Understanding these microbial patterns helps clarify ecosystem function in freshwater lakes.
Water Bacterial and Fungal Community Compositions Associated with Urban Lakes, Xi’an, China
Bacterial and fungal communities in urban lakes in Xi'an, China were characterized, revealing diverse microbial assemblages influenced by nutrient levels and land use in the surrounding watershed. Understanding the microbial ecology of urban lakes provides context for how microplastic-associated microbial communities might interact with existing water quality challenges.
Soil-Microbial CNP Content and Ecological Stoichiometry Characteristics of Typical Broad-Leaved Tree Communities in Fanjing Mountain in Spring
This paper is not about microplastics; it examines soil microbial carbon, nitrogen, and phosphorus stoichiometry across four subtropical forest types in Fanjing Mountain, China, to understand nutrient cycling and microbial nutrient limitations.
Application of Organic Fertilizer Changes the Rhizosphere Microbial Communities of a Gramineous Grass on Qinghai–Tibet Plateau
Researchers examined how organic fertilizer application altered rhizosphere microbial communities in a gramineous grass, finding significant shifts in bacterial diversity and composition that may influence nutrient cycling and soil health in grassland ecosystems.
How Organic Mulching Influences the Soil Bacterial Community Structure and Function in Urban Forests
Researchers tested how different types of organic mulch affect the bacterial communities in urban forest soils. They found that wood chips and compost changed the soil's chemical properties and shifted the types of bacteria present, particularly those involved in carbon and nitrogen cycling. The study suggests that organic mulching could be a practical tool for improving the microbial health of urban soils.
Short‐term effects of mineral and combined mineral‐organic fertilization in soil microbial communities
A one-year fertilization trial in a Qinghai-Tibet Plateau greenhouse found that both mineral and combined mineral-organic fertilization increased bacterial richness and decreased fungal diversity compared to unfertilized soil, with available phosphorus as the primary driver of microbial community structure changes.
[Distribution Characteristics of Microplastic Surface Bacterial Communities Under Flooded and Non-flooded Conditions in Nanjishan Wetland of Poyang Lake].
A 16S sequencing study of bacterial communities in the Poyang Lake wetland found that microbial diversity on microplastic surfaces was lower than in surrounding sediment and water, with the microplastic biofilm community shifting between sediment-like (non-flooded) and water-like (flooded) profiles depending on water level. The plastisphere communities were dominated by distinct bacterial genera including elevated Proteobacteria, suggesting that microplastics select for specific microbial assemblages in natural wetland ecosystems.
Bacterial community structure of water, sediment and microplastics in Poyang Lake wetland.
This study compared the bacterial communities living on four types of microplastics (film, foam, fiber, and fragment) in Poyang Lake wetland in China against the bacterial communities in the surrounding water and sediment. The microplastic surfaces hosted distinct microbial communities that differed from both the water and sediment, with foam microplastics supporting the least diverse communities. This "plastisphere" research is important because the unique bacteria colonizing plastic surfaces could spread pathogens or alter nutrient cycles in freshwater wetland ecosystems.
