Ocupação espacial, alimentação e época reprodutiva de duas espécies de Corydoras Lacépède (Siluroidei, Callichthyidae) coexistentes no rio Alambari (Botucatu, São Paulo)
Provedor de dados: 104
Autores: Aranha,José Marcelo R.; Caramaschi,Érica P.; Caramaschi,Ulisses.
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.

Feeding of two sympatric species of Characidium, C. lanei and C. pterostictum (Characidiinae) in a coastal stream of Atlantic Forest (Southern Brazil)
Provedor de dados: 52
Autores: Aranha,José Marcelo R.; Gomes,José Henrique C.; Fogaça,Fábio N. 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...

Macroinvertebrate fauna associated to the bromeliad Vriesea inflata of the Atlantic Forest (Paraná State, southern Brazil)
Provedor de dados: 52
Autores: Mestre,Luiz Augusto M.; Aranha,José Marcelo R.; Esper,Maria de Lourdes P.
The accumulated water inside the bromeliad leaf rosette is a microhabitat for several animal and plant species. In this study, the associated fauna of bromeliad Vriesea inflata was analyzed related to seasons, bromeliad height in relation to the ground and environmental factors. The samples were seasonally collected in Quatro Barras (a municipality of Paraná State, southern Brazil) between March 1996 and March 1997. The associated fauna was very rich and it was grouped in 23 taxonomic groups, with a dominance of Coleoptera Scirtidae, Diptera and Hymenoptera Formicidae. We found higher abundance of macroinvertebrates in terrestrial bromeliads during the spring/1996 and in epiphyte bromeliads in the autumn/1997.
