Dominant fish face higher microplastic risk than subordinates in social groups
A study led by the University of Glasgow found that dominant European minnows in social hierarchies are more likely to ingest microplastics, particularly in flowing water. The research suggests that behavioral traits providing a competitive advantage in food acquisition can increase vulnerability to pollution.
