- W1569307263 abstract "Diets of two species of Bryconamericus Eigenmann, 1907 called Bryconamericus sp. 1 and Bryconamericus sp. 2, were compared. Collections were made monthly, from March 1997 to February 1998, on the Iguaçu River, State of Paraná. Both species are insectivores, but Bryconamericus sp. 1 feed predominantly on larvae of aquatic insects and Bryconamericus sp. 2 feed on terrestrial insects. In Bryconamericus sp. 1, the mouth is sub-inferior with slightly thick upper lip, while in Bryconamericus sp. 2 the mouth is anterior with reduced lip; teeth are different in both species, confirming differences in feeding tactics. The length of the intestine is significantly longer in Bryconamericus sp. 1. This particularity and the low overlap values (< 0.60) suggest that interspecific differences in feeding habits play an important role, allowing species coexistence" @default.
