Última Geographic variation of Moenkhausia bonita (Characiformes: Characidae) in the rio de la Plata basin, with distributional comments on M. intermedia Neotropical Ichthyology Vanegas-Ríos,James Anyelo; Britzke,Ricardo; Mirande,Juan Marcos. ABSTRACT Moenkhausia bonita occurs in numerous additional localities from the Bermejo, Paraná, Paraguay, and Uruguay river basins. Given that this finding greatly expands the distributional range of M. bonita, we carried out an intraspecific comparison, using multivariate methods for 18 morphometric and eight meristic characters taken from a comprehensive sample of 536 specimens. All localities were distributed in four major geographic groups as follows: Bermejo, Paraná, Paraguay, and Uruguay. Results of the morphometric comparisons showed significant differences among the studied groups except between the Paraguay and Uruguay groups. Statistical differences in meristic values were found for most between-group comparisons, especially in those resulting...

This study analyzed the diet of seven small-sized fish species (Characidae) and assessed their use of food resources. The species were collected in 2001 from nine ponds with aquatic macrophytes in the Paraná river floodplain, Brazil. Astyanax altiparanae, Astyanax fasciatus, Hemigrammus marginatus and Moenkhausia intermédia consumed aquatic and terrestrial insects. Bryconomericus stramineus and Moenkhausia sanctaefilomenae co-dominantly ate insects and microcrustaceans, whereas Hyphessobrycon eques had microcrustaceans as their most important food resource. Overlapping feeding coefficients varied from intermediate (0.4-0.6) to low (< 0.4) for the majority of the combination pairs. A high mean intestinal length was verified for A. altiparanae and A....
