Seasonal diet shifts of seven fish species in an Atlantic rainforest stream in Southeastern Brazil.
We analyzed the stomach contents of 116 individuals belonging to seven fishes species in order to investigate seasonal changes in feeding strategy and how trophic interactions between species affect community structure in an Atlantic rainforest stream in Southeastern Brazil. Oligosarcus hepsetus and...
