Transgenerational effects on development following microplastic exposure in Drosophila melanogaster
AI summary Read the abstract
Researchers fed Drosophila melanogaster flies plastic-supplemented food and found that while treated flies showed changes in fertility and sex ratio, their unexposed offspring had shorter larval development and reduced adult size, demonstrating transgenerational developmental effects from parental microplastic exposure.
Flies treated with plastics in the food media showed changes in fertility and sex ratio, but showed no differences in developmental times, adult size or the capacity to fight infections in comparison with controls. However, the offspring of treated flies reared in non-supplemented food had shorter life cycles, and those coming from both polyvinyl chloride treatments were smaller than those offspring of controls.

Researchers tracked multigenerational effects of weathered polyethylene microplastics on Drosophila melanogaster, finding that fitness effects including reduced fecundity and lifespan became more pronounced in later generations even when offspring were not directly exposed.
Peer Review #1 of "Transgenerational effects on development following microplastic exposure in Drosophila melanogaster (v0.1)"
AI summary Read the abstract
This is a peer review document evaluating a study on transgenerational effects of microplastic exposure in Drosophila fruit flies. The underlying research examined whether microplastics affect fly life history traits and immune responses in ways that persist across generations.

This is a second peer review document evaluating the same study on transgenerational microplastic effects in Drosophila fruit flies. The study being reviewed investigated whether plastic exposure harms development, survival, and immunity across fly generations, which is relevant to understanding long-term biological impacts of plastic pollution.
Multigenerational Effects of Weathered Polyethylene Microplastics on Drosophila melanogaster
AI summary Read the abstract
Researchers exposed four generations of fruit flies (Drosophila melanogaster) to weathered high-density polyethylene microplastics and monitored their reproductive performance. The study found that while the microplastics were not lethal at the concentrations tested, several fourth-generation flies developed malformed salivary glands and scutella, indicating that multigenerational microplastic exposure may cause subtle developmental effects even without obvious toxicity.
A mini review on exposure of microplastic to Drosophila melanogaster causing sex-specific, transgenerational, locomotory, physiological and developmental effect
AI summary Read the abstract
This mini-review synthesized studies on how polystyrene and PET microplastics affect Drosophila melanogaster across multiple biological levels including sex-specific responses, physiology, behavior, development, and transgenerational effects. Male Drosophila showed greater sensitivity to microplastics with higher mortality, and effects were both concentration- and size-dependent.
