ClearChemical pollution and microbiomes responses
This paper reviewed how chemical pollution affects microbial community composition and function across different environments. Exposure to pollutants including plastics, heavy metals, and pesticides can disrupt microbial diversity and the ecosystem services microbes provide. The review calls for greater integration of microbiome science into environmental risk assessment.
Microplastics predominantly affect gut microbiota by altering community structure rather than richness and diversity: A meta-analysis of aquatic animals
A phylogenetically controlled meta-analysis of 63 studies across 31 aquatic species found that microplastics significantly alter gut microbiota community structure — with between-group distances 87.75% higher than within-group distances — even at environmentally relevant concentrations. However, microplastics did not significantly affect species richness or Shannon diversity, indicating structural reorganization rather than diversity loss.
Microbiomes of the Aquatic Environment
This review examines the diversity and ecological roles of microbial communities in aquatic environments, covering microbiomes associated with aquatic insects, plants, fish, phytoplankton, macrophytes, and microplastics, and their interconnected functions in nutrient cycling and primary production. The authors discuss how climate change, eutrophication, and pollution are shifting microbial community composition in ways that threaten the functioning of freshwater and marine ecosystems.
Microbiome: A forgotten target of environmental micro(nano)plastics?
This review examines how micro- and nanoplastics affect the microbiome of various organisms, an area that has received less attention than other toxicological endpoints. Researchers found that most studies focused on polystyrene particles and that exposure consistently disrupted microbiome composition, triggered immune responses, and altered enzyme activity across organisms including crustaceans, fish, and mammals. The study highlights the microbiome as an important but often overlooked target of microplastic pollution.
The effects of exposure to microplastics and pollutants on the arthropod microbiome
This thesis investigated how microplastics and other pollutants (pesticides, detergents, metals) affect the gut microbiome of freshwater invertebrates. Disruption of the host-microbiome relationship by microplastics could impair immune function and overall health in aquatic organisms that form important parts of the food web.
Iva xanthiifolia leaf extract reduced the diversity of indigenous plant rhizosphere bacteria
Researchers investigated how Iva xanthiifolia leaf extract altered the diversity of indigenous plant rhizosphere bacteria, finding that the invasive plant's leaf material reduced bacterial diversity and may facilitate invasion by disrupting the native soil microbiome.
Ecological risks in a ‘plastic’ world: A threat to biological diversity?
This review synthesized evidence on how microplastic pollution affects biological diversity and community structure across aquatic and terrestrial ecosystems, finding that most studies document effects at the individual level but that community- and ecosystem-level impacts remain poorly characterized.
How microplastics influence the health and microbiota of aquatic invertebrates: A review
This review examines how microplastics affect the health and microbiota of aquatic invertebrates, an area that has received less attention than fish studies. Researchers summarize evidence showing that microplastics cause toxicity at biological and molecular levels, alter microbial communities associated with invertebrate hosts, and interact with climate change and other pollutants to produce combined effects. The study highlights significant knowledge gaps and proposes future research directions for understanding microplastic impacts on aquatic ecosystems.
Improving the assessment of ecosystem and wildlife health: microbiome as an early indicator
Researchers reviewed evidence that the microbiome — the community of microorganisms living in environments and within animals — can serve as an early warning system for ecosystem disturbance, rapidly reflecting the impact of human activities before other signs of harm are visible.
Nonbiodegradable microplastic types determine the diversity and structure of soil microbial communities: A meta-analysis
A global meta-analysis of 95 studies found that nonbiodegradable microplastics increased soil active microbial biomass by 42% while simultaneously decreasing bacterial Shannon and Chao1 diversity indices by 2-3%. This paradox suggests microplastics promote the growth of specific microbial taxa while suppressing overall diversity, potentially disrupting soil biogeochemical cycles.
Microplastics negatively affect soil fauna but stimulate microbial activity: insights from a field-based microplastic addition experiment
A meta-analysis of microplastic studies found that microplastics negatively affect soil fauna abundance and diversity while stimulating soil microbial activity, based on data from multiple laboratory experiments. The opposing effects on fauna and microbes suggest that microplastics can shift soil community structure in ways that alter ecosystem functions like decomposition and nutrient cycling.
Asymmetric succession in soil microbial communities enhances the competitive advantage of invasive alien plants
Researchers found that invasive plant species gain a competitive edge by recruiting beneficial soil microbes from surrounding native soil, creating an "asymmetric" shift where invasive plants build supportive microbial communities faster than native plants can. This biological feedback loop helps explain why invasive plants spread so successfully and points to new strategies for controlling them.
Microplastic exposure across trophic levels: effects on the host–microbiota of freshwater organisms
Researchers examined how microplastic exposure across trophic levels affects the gut microbiota of freshwater organisms, finding that microplastics alter microbial community composition and that effects can transfer through food web interactions.
Abiotic and Biotic Effects on Microbial Diversity of Small Water Bodies in and around Towns
Metagenomic analysis of microbial communities in nine small urban water bodies across four seasons found that water quality had a greater influence on microbial community structure than habitat type, with alien species also contributing significantly to microbial diversity shifts.
Rhizosphere Keystone Microbiomes Promote Invasive Plant Growth under PLA and PVC Microplastic Stress: A Comparative Study with Native Species
Researchers compared how invasive and native plant species respond to soil contaminated with biodegradable and non-biodegradable microplastics. Invasive plants experienced less growth inhibition and selectively enriched beneficial bacteria in their root zones, forming more stable microbial networks. The study suggests that microplastic contamination in soils may inadvertently give invasive species a competitive advantage over native plants.
Global meta-analysis reveals differential effects of microplastics on soil ecosystem
This meta-analysis pooled data from 114 studies to understand how microplastics affect soil ecosystems at different concentrations. Higher microplastic levels reduced soil organic matter and microbial activity, suggesting that increasing plastic pollution could degrade the soil that supports our food supply.
Microplastics alter the equilibrium of plant-soil-microbial system: A meta-analysis
This meta-analysis pools data from multiple studies to show that microplastics disrupt the balance between plants, soil, and soil microbes. The effects vary depending on the type, size, and concentration of microplastics, suggesting that these tiny plastic particles can alter how nutrients cycle through the soil and ultimately affect the food we grow.
RhizosphereKeystoneMicrobiomes Promote InvasivePlant Growth under PLA and PVC Microplastic Stress: A ComparativeStudy with Native Species
A mesocosm experiment compared the growth responses of invasive and native plant species to PLA (biodegradable) and PVC (conventional) microplastics in soil. Invasive plants outperformed native species under MP stress partly due to shifts in rhizosphere keystone microbiomes, suggesting microplastics may amplify invasion success.
Meta-analysis reveals differential impacts of microplastics on soil biota
Soil microplastic contamination ranged from 0.34 to over 410,000 items/kg across sites, and their presence significantly increased mortality rates and decreased individual numbers, diversity, and reproduction of soil organisms, though biomass was unaffected due to opposing effects on different organism groups.
Effects of microplastics pollution in sediments on physicochemical properties and microbial community distribution in coastal Spartina alterniflora-invaded wetlands
This study examined how microplastic pollution in sediments affects the physicochemical properties and microbial communities of coastal wetlands invaded by Spartina alterniflora. MP contamination combined with invasive plant spread altered sediment nitrogen cycling and microbial diversity, compounding ecological degradation in these coastal ecosystems.
