Chronic exposure to polyethylene and tire wear particles changes the associative preferences in cyprinid fishes
Summary
This study exposed native crucian carp and invasive gibel carp to polyethylene and tire wear particle microplastics over time, finding that chronic exposure altered associative preferences in both species. The results suggest that microplastic pollution may affect cognitive functions in fish and could influence competitive dynamics between native and invasive species.
This study aims to contribute to our understanding of how pollution with different microplastic types such as polyethylene and tire wear particles affects cognitive functions of the native crucian carp and invasive gibel carp, and to explore the potential competitive advantages of invasive gibel carp in polluted environments. The findings will provide insights into the broader implications of pollutants on the species social associative skills.
