“…This feature corroborates the omnivorous habits of the genus, as observed in several other studies (Breeder, 1927;Menezes, 1969;Knöpell, 1970;Goulding, 1980;Borges, 1986;Horn, 1997;Sabino & Sazima, 1999;Lima & Castro, 2000;Leite & Araujo-Lima, 2002;Drewe et al, 2004;Leite, 2004;Albrecht et al, 2009). These studies show a considerable range of food items consumed by the Brycon species such as: plant debris, terrestrial and aquatic insects, small fish, and terrestrial vertebrates.…”

“…In the sample of the Rio Urubaxí (12-17.5mm standard length), 4 had more or less empty stomachs except for a few chitin bits, and one stomach contained a fresh, adult ant. The cardinal thus shows similar feeding habitats as other small characiforms of the Rio Negro Basin (Leite and Araújo-Lima 2002;Goulding et al 1988). The internal anatomy of P. axelrodi agrees with a predatory mode of feeding in teleost fishes: The stomach is voluminous, and the gut is short, at best twice the length of the body cavity (Ziswiler 1976).…”

“…A elevada concentração de larvas capturadas na estação E16 ao longo do rio Xingu demonstra a importância das áreas de bocas de canais de lago para o desenvolvimento das larvas que utilizam estes ambientes como locais de dispersão. Esse agrupamento próximo às futuras áreas de inundação pode se tratar de uma estratégia larval, uma vez que algumas espécies da ictiofauna amazônica utilizam os ambientes lacustres como áreas de abrigo e forrageio, durante as fases iniciais de desenvolvimento, favorecendo desta maneira a sobrevivência da prole (LEITE; ARAÚJO-LIMA, 2002). Sugere-se que estas regiões de confluência de lagos e rios funcionem como importantes áreas de estímulo para desova desses peixes e indicam o uso destes habitats como zona de colonização e dispersão larval.…”
