What is it about?

This research shows that the diet of silverside, Atherinella brasiliensis, becomes poorer and dominated by few dietary items after the impoverishment of prey items in an heavily disturbed system with a nutrient enrichement associated with higher human activity.

Why is it important?

The present findings suggest that the diet of A. brasiliensis could be a useful indicator of changes in the ecological quality in tropical estuaries.

The specimens collected in the most impacted estuary also had a greater frequency of microplastics and parasites in their stomachs, and this needs be best understood as soon as possible.
