ClearSpatiotemporal 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.
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.

The study found meaningful differences in microbial community composition between the two sites, reflecting local environmental influences.

Spatiotemporal changes of cyanobacterial and bacterial communities during an algal bloom in a subtropical water source reservoir ecosystem of China
Researchers used high-throughput 16S rRNA sequencing to investigate spatiotemporal variation in cyanobacterial and bacterial community diversity and composition across different phases of an algal bloom in a eutrophicated subtropical reservoir in China. Results showed temporal significance in community structure for both cyanobacteria and bacteria across bloom phases, with spatial variation also observed along upstream river inputs.
Responses of Free-Living Vibrio Community to Seasonal Environmental Variation in a Subtropical Inland Bay
Researchers used Vibrio-specific 16S rRNA sequencing to characterize seasonal distribution and diversity of free-living Vibrio communities in the Maowei Sea, finding that Shannon diversity peaked in summer while community composition shifted with temperature and nutrient availability, revealing how seasonal eutrophication shapes the dynamics of this pathogen-relevant bacterial genus.
Spatiotemporal changes of cyanobacterial and heterotrophic bacterial communities during an algal bloom in a subtropical water source reservoir ecosystem of China
Researchers used high-throughput sequencing to track how cyanobacterial and heterotrophic bacterial communities in a Chinese reservoir changed spatially and temporally across distinct algal bloom phases. They found that algal bloom progression drove significant shifts in microbial diversity and community composition, with dominant taxa including Cyanobacteriales and genera such as Acinetobacter and Flavobacterium varying across bloom stages.
Spatial and Temporal Variations in Phytoplankton Community in Dianchi Lake Using eDNA Metabarcoding
This paper is not about microplastic pollution. It uses environmental DNA metabarcoding to study phytoplankton communities in Dianchi Lake, China, identifying seasonal and spatial variation in algal species and the environmental factors that drive those changes.
Microplastic-associated bacterial assemblages in the intertidal zone of the Yangtze Estuary
Researchers used high-throughput DNA sequencing to profile bacterial communities colonizing microplastics in the intertidal zone of China's Yangtze Estuary, finding that plastisphere community composition reflected the particles' sedimentary versus aquatic origins and included keystone taxa adapted to surface-colonization as well as potential pathogens hitchhiking on plastic surfaces.
Can Microplastic Pollution Change Important Aquatic Bacterial Communities?
Microplastics in coastal sediments can change the composition of important bacterial communities that cycle nutrients and maintain ecosystem health. Microplastic-associated bacteria differ significantly from natural sediment bacteria, with potential consequences for the chemical processes these communities perform.
Seasonal biofilm formation on floating microplastics in coastal waters of intensified marinculture area
Researchers investigated seasonal biofilm formation on floating polyethylene and polypropylene microplastics in four coastal mariculture zones in southeast China, finding that biofilm bacterial community composition differed less between winter and summer than the surrounding planktonic bacteria. The results suggest biofilms on microplastics provide a buffering microenvironment that stabilizes bacterial communities across seasons.
