ClearInteracting effects of simulated eutrophication, temperature increase, and microplastic exposure on Daphnia
This study examined the interacting effects of simulated eutrophication (increased cyanobacteria from 5% to 95% of food), temperature increase (+3 degrees C), and microplastic exposure on Daphnia in freshwater systems. Multiple stressors combined in ways that differed from single-stressor experiments, underscoring the complexity of predicting ecological outcomes from simultaneous environmental pressures.
Synergistic effects of water temperature, microplastics and ammonium as second and third order stressors on Daphnia magna
Combining water temperature, microplastics, and ammonium as stressors produced synergistic negative effects on the water flea Daphnia magna, reducing its filtration capacity and survival more than any single stressor alone. The findings are relevant to wastewater treatment, where Daphnia are used to filter particles and could face such combined stressors.
Long-term adverse effects of microplastics on Daphnia magna reproduction and population growth rate at increased water temperature and light intensity: Combined effects of stressors and interactions
Researchers investigated how increased water temperature and light intensity affect the long-term toxicity of microplastics to the water flea Daphnia magna. They found that microplastics caused mortality, reduced growth, and decreased reproduction across all conditions, but these effects were significantly worsened by both higher temperature and brighter light. The study suggests that climate change factors may synergistically amplify the harmful impacts of microplastic pollution on freshwater zooplankton.
Impacts of microplastics and pesticides on Daphnia
Researchers investigated the combined and individual impacts of microplastics and pesticides on Daphnia magna, a model crustacean widely used in freshwater ecotoxicology, to assess how these co-occurring pollutants affect aquatic ecosystem health. The study examined survival, reproduction, and physiological responses in D. magna exposed to varying concentrations of both stressors under controlled conditions.
Effect of Polystyrene Microplastics in Different Diet Combinations on Survival, Growth and Reproduction Rates of the Water Flea (Daphnia magna)
Researchers exposed Daphnia magna water fleas to 6-micrometer fluorescent polystyrene microplastics across different diet combinations over 21 days, finding that animals fed only microplastics showed survival declines similar to starved controls and the least growth, while algae co-feeding partially mitigated but did not eliminate reproductive impacts.
The thermal regime modifies the response of aquatic keystone species Daphnia to microplastics: Evidence from population fitness, accumulation, histopathological analysis and candidate gene expression
Researchers found that temperature plays a key role in how toxic microplastics are to the water flea Daphnia magna. Microplastic exposure caused increased mortality, reduced reproduction, and slower population growth, with these negative effects becoming much more pronounced at higher temperatures. The study suggests that warming water temperatures due to climate change may amplify the harmful impacts of microplastic pollution on aquatic ecosystems.
Effects of Microplastics on Reproduction and Growth of Freshwater Live Feeds Daphnia magna
Researchers found that microplastic exposure negatively affected reproduction and juvenile growth in Daphnia magna, a key freshwater zooplankton species, with effects worsening at higher concentrations and posing risks for aquatic food chains.
Combined effect of microplastics and tire particles on Daphnia magna: Insights from physiological and transcriptomic responses
Researchers investigated the combined effects of microplastics and tire particles on the water flea Daphnia magna, finding that the mixture triggered significant oxidative stress at environmentally relevant concentrations. Transcriptomic analysis revealed upregulation of antioxidant and metabolic stress genes, while energy reserves like glycogen were affected. The study suggests that co-exposure to these common freshwater pollutants may pose greater ecological risks than either particle type alone.
Warming temperatures exacerbate effects of microplastics in a widespread zooplankton species.
This study found that warmer water temperatures made microplastics significantly more harmful to Daphnia (water fleas), reducing their survival and reproduction at 20 and 24 degrees Celsius but not at 12 degrees. The combination of warming temperatures and microplastic pollution was worse than either stressor alone. As climate change warms lakes and rivers, this research suggests that the toxic effects of microplastic pollution on aquatic ecosystems, and the food chains humans depend on, may get worse.
Combined effects of nanoplastics and elevated temperature in the freshwater water flea Daphnia magna
This study found that polystyrene nanoplastics became more toxic to water fleas (Daphnia magna) at higher temperatures, causing more oxidative stress and a greater drop in reproduction. Warmer conditions increased how much plastic the organisms absorbed and accumulated. The findings suggest that as global temperatures rise, the harmful effects of nanoplastic pollution on aquatic life could get worse, potentially affecting species that are important food sources for fish.
Effects of microplastics on key reproductive and biochemical endpoints of the freshwater microcrustacean Daphnia magna
Researchers studied how microplastics affect reproduction and biochemistry in the freshwater water flea Daphnia magna, a widely used indicator species. They found that microplastic exposure led to changes in reproductive output and altered key biochemical markers in these small crustaceans. The study suggests that even tiny plastic particles can disrupt important biological functions in freshwater organisms that form the base of aquatic food webs.
The synergistic effect of mono and co-exposure of microplastic suspensions on Daphnia magna’s survival, population density, reproduction rate & swimming behavior.
When water fleas (Daphnia magna) were exposed to mixtures of HDPE, LDPE, and polypropylene microplastics together, the combined toxicity was substantially greater than any single polymer alone, with the mixture LC50 dropping to 77 mg/L compared to 109–123 mg/L for individual plastics. This synergistic effect — reducing survival, reproduction, and normal swimming behavior — is an important finding because organisms in nature encounter mixtures of plastic types, not just one at a time.
The Effects of Natural and Anthropogenic Microparticles on Individual Fitness in Daphnia magna
Researchers compared the effects of natural and anthropogenic microparticles on the fitness of the water flea Daphnia magna. The study found that both primary microplastics from cosmetic products and secondary microplastics from degraded plastic waste can have detrimental effects on zooplankton feeding and fitness, with particle shape and weathering influencing toxicity.
Effects of combined nutrient and pesticide exposure on algal biomass, and Daphnia magna abundance
This study tested how fertilizers and pesticides, alone and combined, affect tiny water organisms (Daphnia) and algae growth. Higher pesticide levels killed off Daphnia populations while allowing algae to bloom unchecked, disrupting the natural balance of aquatic ecosystems. While not directly about microplastics, these findings are relevant because microplastics in water can carry pesticide residues, potentially amplifying these harmful effects on the organisms that form the base of aquatic food webs.
Warming, temperature fluctuations and thermal evolution change the effects of microplastics at an environmentally relevant concentration
Researchers examined how warming temperatures, daily temperature fluctuations, and thermal evolutionary history influence the effects of microplastics on the water flea Daphnia magna. They found that while microplastics had almost no effect under standard laboratory temperature conditions, exposure under more realistic warming scenarios caused significant changes to reproduction, heart rate, and swimming behaviour. The study suggests that current risk assessments conducted at constant laboratory temperatures may substantially underestimate the ecological impact of microplastic pollution.

Multi-omics characterisation of Daphnia magna exposed to PFAS and microplastics: transcriptome and gut microbiome datasets
Researchers generated a multi-omics dataset from Daphnia magna exposed to environmentally relevant concentrations of PFOS, PFOA, and PET microplastics, integrating gut microbiome 16S rRNA profiling and whole-organism transcriptomes to enable systems-level investigation of host-microbiome interactions under complex contaminant stress.
Combined toxicity of perfluoroalkyl substances and microplastics on the sentinel species Daphnia magna: Implications for freshwater ecosystems
This study tested how PFAS chemicals (common industrial pollutants) and PET microplastics affect water fleas, both alone and together. The combination caused worse developmental and reproductive problems than either pollutant alone, and organisms with prior chemical exposure history responded differently, showing that microplastics can amplify the harm of other environmental contaminants in ways that are difficult to predict.
Beyond microplastics: Water soluble synthetic polymers exert sublethal adverse effects in the freshwater cladoceran Daphnia magna - experimental Dataset
This is a raw experimental dataset accompanying a study showing that water-soluble synthetic polymers cause harmful effects in the freshwater crustacean Daphnia magna. The data support research suggesting that dissolved plastic polymers — not just solid microplastic particles — can pose risks to aquatic organisms.
Effects of Microplastics on Aquatic Animals: A Case Study on Daphnia
Researchers exposed Daphnia water fleas to ten types of virgin plastic materials (HDPE, LDPE, PA, PVC, PP, PS, TPU, etc.) and measured survival, reproduction, and behavioral endpoints, finding that PVC and certain engineering plastics caused the greatest acute toxicity while softer polyolefins had lower effects.
Interactive effects of warming and microplastics on metabolism but not feeding rates of a key freshwater detritivore
Freshwater detritivores were exposed to microplastics at environmentally realistic concentrations under two temperature conditions to separate and combine effects, finding that warming and microplastics interacted to significantly increase metabolic rates but had no combined effect on feeding rates. The results highlight the importance of considering multiple stressors when assessing freshwater organism responses to microplastics under climate change.
Action of Surfactants in Driving Ecotoxicity of Microplastic-Nano Metal Oxides Mixtures: A Case Study on Daphnia magna under Different Nutritional Conditions
This study tested how surfactants (found in detergents and cleaning products) interact with microplastics and metal oxide nanoparticles to affect the toxicity of these combined pollutants on water fleas (Daphnia magna). Surfactants increased the toxicity of microplastic-nanoparticle mixtures, and the effect varied with the age and nutritional status of the test organisms. This highlights how the complex real-world mixture of pollutants in waterways can be more harmful than any single contaminant alone.
Ecotoxicology of microplastics in Daphnia: A review focusing on microplastic properties and multiscale attributes of Daphnia
This review synthesizes research on how microplastics affect Daphnia, a key organism in aquatic food webs, across individual, population, and community levels. Researchers found that the toxicity of microplastics to Daphnia depends heavily on the physical and chemical properties of the particles, and that combined exposure with other pollutants can produce more severe effects. The study highlights Daphnia as an important indicator species for understanding how microplastic pollution cascades through aquatic ecosystems.
