Chronic poly(l-lactide) (PLA)- microplastic ingestion affects social behavior of juvenile European perch (Perca fluviatilis)
AI summary Read the abstract
Researchers fed juvenile perch a biodegradable plastic (PLA) for six months and found it significantly altered their social behavior, making them more reactive to other fish. While PLA did not affect growth or gene expression, it reduced locomotion and predator responses. The study suggests even biodegradable plastics can have behavioral toxicity in aquatic animals.
Impact of Microplastics on Reproductive and Physiological Aspects of Aquatic Inhabitants
AI summary Read the abstract
Researchers reviewed how microplastic exposure affects reproduction and physiology in freshwater aquatic organisms, finding that plastic particles disrupt hormonal signaling, reduce fertility, and impair development across a range of sensitive freshwater species.
Acute Effects of Size Dependent Low-Density Polyethylene Microplastics on Zebrafish
AI summary Read the abstract
Zebrafish embryos exposed to low-density polyethylene microplastics for 48 hours accumulated particles in their gut, experienced reduced hatching rates, increased heart rates, and significant tissue damage, with smaller particles causing the most harm. These acute effects in a widely used model organism suggest that even brief early-life exposure to plastic particles can disrupt normal development.
Data file to 'Chronic poly(L-lactide) (PLA)- microplastic ingestion affects social behavior of juvenile European perch (Perca fluviatilis)'
AI summary Read the abstract
This is the raw data file for a study examining how chronic ingestion of polylactic acid (PLA) microplastics affects the social behavior of juvenile European perch. The data support findings that biodegradable plastic microparticles can alter the behavior of freshwater fish, even at relatively low exposure levels.
Physiological Alterations and Immune Modulation in Fish Exposed to Microplastics
AI summary Read the abstract
Researchers reviewed the physiological and immunological effects of microplastic exposure in fish, finding that these particles smaller than 5 mm induce a range of biological disruptions including immune modulation, oxidative stress, and systemic health impacts with broader implications for aquatic ecosystem integrity.
