Data for: Polystyrene nanoplastics differentially influence the outcome of infection by two microparasites of the host Daphnia magna

AI summary Read the abstract

This is a duplicate dataset entry supporting the same study on polystyrene nanoplastics and microparasite infection in Daphnia magna. It is a data repository record rather than an original research paper.

Polystyrene nanoplastics differentially influence the outcome of infection by two microparasites of the host Daphnia magna

AI summary Read the abstract

Researchers exposed the water flea Daphnia magna to two different parasites in the presence of polystyrene nanoplastics. The study found that nanoplastic exposure dramatically increased infection rates by a fungal parasite while having no significant effect on a gut microsporidium, suggesting that nanoplastics can differentially affect host-parasite relationships and potentially favor parasite coexistence in aquatic environments.

Size Matters: The Effects of Polystyrene Nanoplastics on Parasite Transmission in the Daphnia‐Metschnikowia Host–Parasite System

AI summary Read the abstract

Researchers investigated how polystyrene nanoplastic size affects parasite transmission between aquatic hosts, finding that nanoplastic size influenced infection dynamics by altering host behavior, immune function, or parasite infectivity. Smaller nanoplastics had more pronounced effects on parasite transmission success.

Nanoplastics diversify and reshape Daphnia microbiomes in parasite-infected and uninfected hosts

AI summary Read the abstract

Scientists exposed water fleas (Daphnia magna) to polystyrene nanoplastics of two sizes, with and without a yeast parasite infection, and analyzed changes in their gut and body microbiomes. The smallest nanoplastics at the highest concentration caused the most dramatic shifts in bacterial communities, with effects that exceeded those caused by the parasite alone. The results suggest that nanoplastic pollution could fundamentally reshape the beneficial microbes that aquatic organisms depend on for their health.

Data set and R code for Species-specific life-history responses of Daphnia to PS and PHBV nanoplastics

AI summary Read the abstract

This record is a dataset and accompanying R code, not a full research study. It provides data and analysis tools related to how Daphnia (small water-dwelling creatures) respond over their life cycle to two types of nanoplastics, PS and PHBV, with responses varying by species.
