ClearEvidence for strong environmental control on bacterial microbiomes of Antarctic springtails
Researchers studied the bacterial communities living inside four species of Antarctic springtails (tiny soil insects) and found that geography — where the springtails lived — was a stronger influence on their gut microbiome than which species they were. This finding helps explain how extreme environments shape the microbial ecosystems inside animals, including those exposed to microplastic contamination.
Identification and quantification of macro- and microplastics on an agricultural farmland
Researchers examined how polystyrene microplastics affect the soil-dwelling springtail Folsomia candida and found that exposure altered gut microbiota composition and reduced reproductive output. The microplastics disrupted the balance of beneficial bacteria in the gut of these important soil organisms. The study suggests that microplastic contamination in soils could have broader consequences for soil health by affecting the organisms that help maintain ecosystem functions like nutrient cycling.
Long-term inorganic fertilizer exposure disturbed functional traits and gut bacterial conditionally rare or abundant taxa in collembolan (Entomobrya proxima Folsom)
Researchers examined how long-term inorganic fertilizer application disturbed soil functional traits and gut bacterial communities of earthworms, finding that fertilizer-driven changes in soil chemistry altered earthworm gut microbiomes in ways that may affect soil ecosystem services.
Ecotoxicological Effects of Microplastics in Agricultural Soil Emerge With Increasing Test System Complexity
This doctoral thesis investigated the ecotoxicology of mulching film-derived microplastics on Collembola (soil springtails) in agricultural soil, testing their effects both in single-species assays and in mesocosm experiments designed to reflect more realistic ecosystem-level conditions.
Toxicogenomic Fingerprint Identification in Springtails to Assess Pesticide-Contaminated Soils
Researchers used toxicogenomic fingerprinting in springtails (Collembola) to assess the effects of pesticide-contaminated soils, analyzing gene expression patterns to identify molecular signatures of pesticide exposure in these ecologically important soil invertebrates. The approach identified distinct transcriptomic responses linked to specific pesticide classes, offering a sensitive biomonitoring tool for evaluating soil contamination in agricultural landscapes.

The springtail Folsomia candida was exposed to nanoplastics, antibiotics, and elevated temperature to examine interactive effects on gut microbiome composition in a standard ecotoxicology model organism. The study aimed to understand how combined exposure to these common soil pollutants under warming conditions affects gut microbial communities and ecosystem services.
A new trypan blue agar plate assay for in vivo evaluation of gut damage in Folsomia candida springtail
Researchers developed a simple trypan blue agar plate test to assess gut barrier damage in springtails, a common soil test organism. The method provides an accessible way to measure intestinal injury caused by soil contaminants including microplastics. Expanding toxicological endpoints for springtails improves the ability to detect subtle biological harm in soil organisms used in standard ecotoxicity tests.
Transport of microplastics by two collembolan species
Researchers exposed two species of soil springtails (collembolans) to surface-applied microplastics and found that these small invertebrates can transport plastic particles vertically into deeper soil layers as they move. This is one of the first demonstrations that soil fauna can redistribute microplastics downward in terrestrial ecosystems.
Effects of environmentally relevant mixtures of microplastics on soil organisms
Researchers exposed earthworms and springtails to environmentally realistic mixtures of microplastics commonly found in agricultural soils treated with sewage sludge. They found that earthworms ingested microplastics in proportion to exposure levels, and at higher concentrations, both species showed reduced reproduction. The study provides evidence that real-world microplastic mixtures in farm soils can affect important soil organisms at concentrations already found in the environment.
Soil microplastics inhibit the movement of springtail species
This study found that soil microplastics impeded the movement of springtail species in laboratory experiments, with effects dependent on plastic particle size and concentration, suggesting potential ecological consequences for soil-dwelling invertebrates.
Understanding the ecological effects of the fungicide difenoconazole on soil and Enchytraeus crypticus gut microbiome
Researchers exposed soil-dwelling worms and surrounding soil microbiomes to the fungicide difenoconazole for 21 days, finding reduced body weight and oxidative stress in the worms alongside altered gut and soil microbial communities, with soil metagenomics revealing that bacterial detoxification genes and virus-encoded carbon cycle genes were enriched under pesticide stress.
Responses of a soil-inhabiting collembolan (Entomobrya proxima Folsom) to organic fertilizer addition illustrated by functional traits and gut bacterial community
Researchers investigated how different concentrations of organic fertilizer affect the collembolan Entomobrya proxima at the level of functional traits and gut bacterial community composition. Organic fertilizer addition had multiple concentration-dependent effects on soil fauna, providing insights for optimizing sustainable agricultural management while maintaining soil animal functions.
Exposure to nanoplastics disturbs the gut microbiome in the soil oligochaete Enchytraeus crypticus
Researchers fed the soil oligochaete Enchytraeus crypticus diets containing different concentrations of nano-polystyrene particles and found that exposure significantly altered the gut microbiome composition. The study suggests that nanoplastic ingestion can disturb the microbial communities in soil invertebrate digestive systems, which may have cascading effects on nutrient processing and organism health.
What do we know about how the terrestrial multicellular soil fauna reacts to microplastic?
This review analyzed published studies on how multicellular soil organisms (including earthworms, mites, springtails, and nematodes) ingest and respond to microplastics, finding that most studies used unrealistically high concentrations and that ecologically relevant effects on soil fauna remain poorly characterized.
In vitro assays reveal inherently insecticide-tolerant termite symbionts
Researchers discovered that certain termite gut bacterial symbionts show inherent tolerance to insecticides in vitro, suggesting these microorganisms may contribute to their hosts' resistance and could have applications in environmental bioremediation.
What do we know about how the terrestrial multicellular soil fauna reacts to microplastic?
This review analyzed the available literature on how soil-dwelling animals respond to microplastics and found evidence of uptake, bioaccumulation, and harmful effects across many groups including earthworms, springtails, and beetles. Most studies used high concentrations not yet found in real soils, limiting conclusions about current environmental risks.
Plastics shape the black soldier fly larvae gut microbiome and select for biodegrading functions
Researchers found that black soldier fly larvae can adapt their gut microbiome to digest a wide range of plastics, shifting their microbial communities to favor biodegrading functions. This suggests the insects could serve as living incubators for discovering new plastic-breaking enzymes for industrial cleanup applications.
Effects of common artificial sweeteners at environmentally relevant concentrations on soil springtails and their gut microbiota
Researchers exposed soil-dwelling springtails to four common artificial sweeteners at concentrations found in the environment and observed changes in reproduction, gene activity, and gut bacteria across multiple generations. Initial exposure boosted juvenile production, but long-term exposure over six generations led to reduced reproduction and significant shifts in gut microbial communities. The findings suggest that even trace amounts of artificial sweeteners in soil can have cascading effects on small invertebrates and their microbiomes.
Gammaproteobacteria, a core taxon in the guts of soil fauna, are potential responders to environmental concentrations of soil pollutants
Researchers identified a group of gut bacteria called Gammaproteobacteria as a key indicator of soil pollution stress in soil invertebrates, finding these microbes respond sensitively to environmental contaminants and could serve as a biological signal for assessing soil ecosystem health.
The effects of high-density polyethylene and polypropylene microplastics on the soil and earthworm Metaphire guillelmi gut microbiota
Researchers exposed earthworms to soil amended with high-density polyethylene and polypropylene microplastics for 28 days and examined changes in both the earthworm gut and soil microbial communities. They found that both types of microplastics significantly altered the composition and diversity of gut bacteria in the earthworms. The study suggests that microplastic contamination in soil can disrupt the gut microbiota of soil organisms, with potential consequences for soil ecosystem health.
