ClearMain predictors of phytoplankton occurrence in lotic ecosystems
This paper is not relevant to microplastics research; it examines the environmental and landscape factors controlling phytoplankton community composition in a Brazilian micro-watershed over three years.
Stream Microbial Community Structured by Trace Elements, Headwater Dispersal, and Large Reservoirs in Sub-Alpine and Urban Ecosystems
Researchers measured bacterioplankton community composition across rivers from sub-alpine to urban environments in three Utah watersheds over three seasons to quantify the relative roles of environmental conditions, passive dispersal, and human infrastructure (dams) in shaping stream microbial communities. They found that trace element chemistry and headwater dispersal were primary structuring forces, while large reservoirs imposed distinct downstream community signatures.
Use of multivariate analysis to identify phytoplankton bioindicators of stream water quality in the mono-modal equatorial agro-ecological zone of Cameroon
Researchers monitored phytoplankton communities and water quality parameters in a Cameroonian stream over 12 months, finding that total dissolved solids, electrical conductivity, and flow velocity were the main drivers of community composition, and identifying specific indicator species — including Synedra ulna — that signal low water quality.
Comparison of the Composition and Abundance of Phytoplankton Based on Different Land Use in the Cisadane River, Tangerang Regency
This paper is not about microplastics; it surveys phytoplankton species composition and abundance in the Cisadane River, Indonesia, across sites with different land use types, linking community diversity to water quality parameters like pH and transparency.
Effects of biofouled plastics on phytoplankton community assembling and water chemistry: pilot study and implications for freshwater environments
Researchers conducted a pilot laboratory study exposing a five-species freshwater phytoplankton community to pristine and biofouled polypropylene fragments to investigate whether plastic acts as a carrier for algal species dispersal and to assess effects on water biodiversity and chemistry in freshwater environments.
Cascade dams altered taxonomic and functional composition of bacterioplankton community at the regional scale
Researchers used 16S rRNA gene sequencing to investigate how cascade dams alter bacterioplankton community taxonomy and function at the regional scale in the Shaying River Basin, finding that dam-influenced zones created distinct environments with different community structures and interaction strengths compared to natural river sections.
From the Mountain to the Valley: Drivers of Groundwater Prokaryotic Communities along an Alpine River Corridor
Researchers sampled river water and groundwater from 59 sites along a 300 km transect of the Mur River valley in Austria and Slovenia, finding that dispersal limitation drives microbial community assembly at high altitudes while homogeneous selection dominates in lowland aquifers, with land use being a key determinant of groundwater microbiome composition throughout.
Phytoplankton Communities’ Response to Thermal Stratification and Changing Environmental Conditions in a Deep-Water Reservoir: Stochastic and Deterministic Processes
Researchers studied how thermal stratification in a deep-water reservoir affects phytoplankton community structure and the processes governing species assembly. The study found that both deterministic factors like environmental filtering and stochastic processes influence phytoplankton distribution across water layers. Evidence indicates that prolonged thermal stratification driven by global warming is reshaping aquatic microbial communities in ways that could affect water quality.
Phytoplankton characterization in a tropical tidal river impacted by a megacity: the case of the Saigon River (Southern Vietnam)
Scientists studied how phytoplankton communities vary seasonally and spatially in the Saigon River, Vietnam, finding that urban pollution from Ho Chi Minh City significantly shapes which species dominate. The study provides a baseline for tracking ecological change in a highly impacted tropical river.
The microbial community and functional indicators response to flow restoration in gradient in a simulated water flume
Researchers examined how microbial community structure and functional indicators respond to gradient flow restoration in a simulated water flume, finding that flow regime significantly influences river ecological systems including functional indicators and microbial community composition.
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.
Evaluation of the Influence of Habitat Heterogeneity and Human Activities on the Distribution of Microbial Diversity in a High Elevation Drop River
This is a freshwater microbiology study characterizing bacterial diversity in the Huotong River across different land-use zones in China; it is not a microplastics research paper.
Use of mesocosm and field studies to assess the effects of nutrient levels on phytoplankton population dynamics in Korean coastal waters
Researchers combined mesocosm experiments with field observations to assess how nutrient levels affect phytoplankton populations in Korean coastal waters. The study found that nutrient enrichment shifted phytoplankton community composition, with implications for understanding how runoff and pollution influence coastal ecosystem dynamics.
Differentiation strategies for planktonic bacteria and eukaryotes in response to aggravated algal blooms in urban lakes
Researchers studied how planktonic bacteria and eukaryotes respond differently to worsening algal blooms in urban lakes. The study found that these two groups employ distinct differentiation strategies in response to bloom intensification, and that environmental constraints on plankton communities show different patterns over time, offering insights for managing water quality in urban ecosystems.
Biogeographic gradients of picoplankton diversity indicate increasing dominance of prokaryotes in warmer Arctic fjords
Researchers sampling 21 Arctic and subarctic fjords found that warmer waters favor simple bacterial communities over more diverse microalgae-based communities, suggesting that as climate change heats Arctic seas, the microscopic food web at the base of the ecosystem will shift in ways that could reduce overall productivity.
Transport and retention of microplastic fibers in streams are impacted by benthic algae, discharge, and substrate
Researchers used outdoor experimental streams to measure microplastic fiber transport and retention under varying conditions of benthic algae cover, stream discharge, and substrate size. Higher discharge and algae cover increased downstream transport while coarser substrates and algae promoted retention, showing that biological and physical stream features strongly control microplastic fate in rivers.
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.
Monitoring of Rivers and Streams Conditions Using Biological Indices with Emphasis on Algae: A Comprehensive Descriptive Review toward River Management

Global gradients in species richness of marine plankton functional groups
Researchers modeled global species richness patterns for marine plankton functional groups, finding that diversity peaks in temperate rather than tropical zones for many groups. Plankton are a key part of marine food webs and are sensitive to microplastic contamination, making baseline diversity data important for monitoring ecosystem health.
The role of biofilm and hydrodynamics on the fate of microplastic particles in rivers: an experimental study
Researchers conducted experimental flume studies to investigate how biofilm formation and hydrodynamic conditions jointly govern microplastic particle fate in rivers, examining why some urbanized and industrialized river reaches show no significant upstream-to-downstream increase in microplastic concentration despite theoretical inputs.
