Última Habitat heterogeneity on feeding habit of two sympatric and congeneric characidae fishes in two tropical reservoirs Iheringia, Sér. Zool. Lopes,Vanessa G.; Nessimian,Jorge L.; Da-Silva,Elidiomar R.; Gomes,José Henrique C.; Dias,Ana Carolina I. M.; Souza,Leonardo C.; Branco,Christina W.C.. Abstract Food flexibility and omnivory are important features pronounced in Neotropical freshwater fish species, particularly for Astyanax species. Traditionally most fish diet resources are known to be originated in the aquatic environment, however recent studies have pointed to the importance of allochthonous sources. Besides, the colonization of macrophytes, common at several tropical reservoirs, may enhance insectivory in fish diet expanding or concentrating the area of available resources for feeding. Here we employed stomach contents analysis of two sympatric Astyanax species to access the importance of habitat differentiations as spatial complexity in two tropical reservoirs with different environmental features. The NMDS analysis indicated... Tipo: Info:eu-repo/semantics/article Palavras-chave: Feeding resources; Land-water ecotone; Trophic ecology; Ast yanax aff. bimaculatus; Astyanax parahybae.

O.. The feeding strategy of Characidium lanei and C. pterostictum was studied in the "Cabral" stream, a coastal stream of the Atlantic Forest, in southern Brazil. The samples were taken using electric fishing between March/95 and February/96. We studied about 15 stomach contents for each species in each season of the year. The stomach contents of the studied species were composed of 39 different food items, 28 in C. lanei and 24 in C. pterostictum. Chironomidae larvae and Ephemeroptera nymph were the most important items for C. lanei, except in the summer when Acarina and not identified Arthropoda were the most important items. Chironomidae and Simulidae larvae were the most important items in C. pterostictum. These results indicated an insectivorous habits...
