Resumo

Patterns of spatial occupation, feeding, and reproductive period of two species, Corydoras aeneus and Corydoras gr. carlae (Siluroidei, Callichthyidae), coexistents in the Alambari River (Botucatu, São Paulo), were studied. High diet overlap, partial spatial segregation, and well differentiated reproductive strategies were verified. These findings do not permit to evidence the occurrence of competitive interactions between the analysed species.

ABSTRACT

Patterns of spatial occupation, feeding, and reproductive period of two species, Corydoras aeneus and Corydoras gr. carlae (Siluroidei, Callichthyidae), coexistents in the Alambari River (Botucatu, São Paulo), were studied. High diet overlap, partial spatial segregation, and well differentiated reproductive strategies were verified. These findings do not permit to evidence the occurrence of competitive interactions between the analysed species.

Key words: Siluroidei, Callichthyidae, spatial occupation, feeding; reproductive period
