Última Relationships between morphology, diet and spatial distribution: testing the effects of intra and interspecific morphological variations on the patterns of resource use in two Neotropical Cichlids Neotropical Ichthyology Sampaio,Ana Lúcia A.; Pagotto,João Paulo A.; Goulart,Erivelto. Considering th e morphology, diet and spatial distribution of Satanoperca pappaterraand Crenicichla britskii (Perciformes: Cichlidae) in the Upper Paraná River floodplain (Brazil), the following questions were investigated: (1) Could the body shape predict the use of trophic resources and habitat by C. britskiiand S. pappaterra? (2) Could the relationship between morphology and use of trophic resources and habitat be also extended to the intraspecific scale? (3) What are the most important morphological traits used to predict the variation on diet and habitat occupation within and between species? We hypothesized that intra and interspecific differences in morphological patterns imply in different forms of resource exploitation and that the...

Ano: 2013 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252013000200351 Diet of Crenicichla britskii (Perciformes: Cichlidae) in a stream of Rio Aguapeí basin, Upper Rio Paraná system, southeastern Brazil Biota Neotropica Gibran,Fernando Zaniolo; Ferreira,Katiane Mara; Castro,Ricardo M. C.. We qualitatively studied the gut contents of 20 specimens (36.1-71.3 mm standard length) of the pike cichlid Crenicichla britskii from a 100 m stretched second order stream running inside a small gallery forest in a large pasture area of Rio Aguapeí basin, State of São Paulo, southeastern Brazil. The diet, in terms of per cent composition, constituted primarily of aquatic insects (50%) (mostly immature forms), crustaceans (14.3%), unidentified organic material and filamentous green algae (both with 10.7%), followed by fishes and arachnids (both with 7.1%). Diet analysis indicates that C. britskii is a generalist insectivore with a relatively short digestive tube, which feeds on autochthonous items captured in a broad array of habitats such as in the water...
