Riparian coverage affects diets of characids in neotropical streams
Ecology of Freshwater Fish, 2011Abstract – Aquatic ecosystems are influenced by the surrounding terrestrial environment. This work studied the influence of vegetation of riparian zones on the feeding patterns of two nektonic characids, Astyanax paranae and Bryconamericus iheringii, in a basin surrounded by an agricultural area.

Digestive flexibility during fasting in the characid fishHyphessobrycon luetkenii
Journal of Morphology, 2011AbstractDigestive flexibility is a widespread phenomenon among animals, and the congruence between empirical data and optimal digestion models strongly supports the idea that it has evolved by natural selection. However, current understanding of the evolution of this amazing flexibility is far from being comprehensive.

Aggressive Mimicry by the Characid Fish Erythrinus erythrinus
Ethology, 1997AbstractThe young Erythrinus erythrinus mimics the colour pattern of the female of its specific prey, the cyprinodont fish Rivulus agilae. The male Rivulus is attracted by the predator, and, when performing sexual display in front of it, is caught by the tail and swallowed.

Effect of logged forests on diet of small characids from Neotropical streams
Ecology of Freshwater Fish, 2023AbstractStudies relating to fish trophic ecology provide important insights regarding their life history. However, there is a lack of information linking fish diet composition with riparian cover in small streams. To investigate whether diet composition varied between streams with pristine and logged forests, I compared the food items consumed by four ...

A possible function of the caudal spot in characid fishes
Canadian Journal of Zoology, 1977The suggestion that caudal pigment spots in fishes can act as deflection marks is tested experimentally. Fish with artificial caudal spots escape predators more often than the same species without spots, but the difference was not significant (0.1 < p < 0.2).
