Author Correction: Effects of microplastics on reproductive characteristics and mechanisms of the marine rotifer Brachionus plicatilis
AI summary Read the abstract
This is a correction notice for a previously published study on microplastic effects on marine rotifers (Brachionus plicatilis), fixing typographical errors in the laboratory method description for a gene expression analysis technique. The underlying science of the original paper — examining how microplastics affect reproduction in these small marine animals — is unchanged.
As a result, "Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was performed using 1 L of cDNA template, 0.5 L of forward and reverse primers (10 M), and 10 L of TB Green Premix Ex Taq (2 ) (Takara Bio Inc, Shiga, Japan), making a total volume of 20 L." now reads: "Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was performed using 1 g of cDNA template, 0.5 L of forward and reverse primers (100 M), and 10 L of TB Green Premix Ex Taq (2 ) (Takara Bio Inc, Shiga, Japan), making a total volume of 20 L."

Effects of microplastics on reproductive characteristics and mechanisms of the marine rotifer Brachionus plicatilis
AI summary Read the abstract
Researchers exposed marine rotifers (tiny animals at the base of the ocean food chain) to naturally aged microplastics collected from Japanese coastal waters and found reduced reproduction and population growth. The microplastics triggered oxidative stress and suppressed genes involved in reproduction. Since rotifers are food for many fish species, harm to their populations could ripple up through the food chain.
Author Correction: Airborne microplastic particles detected in the remote marine atmosphere
AI summary Read the abstract
This is a published correction to a research article on airborne microplastic particles detected in the remote marine atmosphere, noting a specific error in the original paper that required correction. The underlying study documented that microplastics are transported to and deposited in remote ocean regions through atmospheric pathways.
Metabolism deficiency and oxidative stress induced by plastic particles in the rotifer Brachionus plicatilis: Common and distinct phenotypic and transcriptomic responses to nano- and microplastics
AI summary Read the abstract
Researchers found that nanoplastics caused stronger reproductive and population growth inhibition in the marine rotifer Brachionus plicatilis than microplastics, with transcriptomic analysis revealing distinct size-dependent toxicity pathways involving metabolism deficiency and oxidative stress.
Correction to: Microplastics in seawater: sampling strategies, laboratory methodologies, and identification techniques applied to port environment
AI summary Read the abstract
This is a correction notice for a previously published paper on microplastic sampling and analysis methods in seawater from port environments. Methodological consistency is important for accurate tracking of microplastic contamination in high-traffic coastal areas.
Impacts of nanoplastics on life-history traits of marine rotifer (Brachionus plicatilis) are recovered after being transferred to clean seawater
AI summary Read the abstract
Marine rotifers (Brachionus plicatilis) were exposed to polystyrene nanoplastics across two generations and then transferred to clean seawater, with results showing that life-history impairments including reduced reproduction recovered after removal of plastic exposure. The finding suggests that nanoplastic effects on zooplankton are reversible upon return to clean conditions, though generational exposure still caused measurable harm.
