Additional file 1 of Microplastic exposure across trophic levels: effects on the host–microbiota of freshwater organisms
AI summary Read the abstract
This dataset file supports a study on microplastic exposure across freshwater food chains, containing raw data from experiments where damselfly larvae were exposed to microplastics and the pesticide deltamethrin individually and in combination. The data tracks how microplastic and pesticide exposure affected damselfly survival and their susceptibility to predation by dragonflies.
Additional file1 (CSV 25 KB) The unprocessed data that was used to perform the predation analysis over time. The damselfly larvae were exposed to the following treatment: microplastics, deltamethrin pesticide, deltamethrin & microplastics, and control. The data showed damselfly survival counts (Survival), dragonfly predation counts (Predation), predation times in minutes (Time), dragonfly IDs (Number), categorical predation times (TimeC), categorical dragonfly IDs (NumberC), damselfly survival percentages (SurvivalP), microplastics as a binomial variable (MP), deltamethrin as a binomial variable (Delta), and the damselflies' survival (SurvivalDam1, SurvivalDam2, and SurvivalDam2).

Researchers found that exposure to 1 µm microplastic beads and the pesticide deltamethrin caused carry-over reductions in microbiome diversity and abundance across a three-level freshwater food chain of daphnids, damselfly larvae, and dragonfly larvae.
Microplastic Exposure Across Trophic Levels: Effects on the Host Microbiota of Freshwater Organisms
AI summary Read the abstract
Researchers investigated how microplastic exposure affects the gut bacteria communities of freshwater organisms including fish, invertebrates, and crustaceans. Microplastics—particularly when combined with pesticides—altered gut microbiota composition, which could impair digestion, immunity, and overall health of freshwater species.
Microplastics enhance Daphnia magna sensitivity to the pyrethroid insecticide deltamethrin: Effects on life history traits
AI summary Read the abstract
Researchers tested whether polyethylene microplastics alter the toxicity of the pyrethroid insecticide deltamethrin to Daphnia magna and found that microplastic presence increased sensitivity to deltamethrin, reducing survival and reproductive output at concentrations that were not toxic without microplastics.
Single and combined effects of microplastics, pyrethroid and food resources on the life-history traits and microbiome of Chironomus riparius
AI summary Read the abstract
Researchers exposed Chironomus riparius larvae to microplastics alone and combined with a pyrethroid pesticide under varying food conditions, finding that combined stress altered life-history traits and shifted the gut microbiome composition, with food availability modulating the severity of effects.
Effects of microplastics on Daphnia-associated microbiomes in situ and in vitro
AI summary Read the abstract
This study investigated how microplastic exposure alters the microbiome associated with Daphnia in freshwater, finding shifts in bacterial community composition that may affect host health and ecological function. The results suggest that microplastics can indirectly harm zooplankton by disrupting their microbial symbionts.
