RESUMO
The present work was carried out with the purpose of studying the biology of the species in a single community of Hylidae. It concentrates on those aspects wihich favor the occurrence of these species in sympatry as well as their maintenance as discret units.The community studied was composed of Hyla albopunctata Spix, 1824; Hyla fuscomarginata A. Lutz, 1925; Hyla fuscovaria A. Lutz, 1925; Hyla sonborni Schmidt, 1944 and Hyla velata Cope, 1887. This community occurs in an open area, altered by human activity, in the municipality of Campinas, State of São Paulo (22º53 S; 47º05 W), where there were permanent and temporary environments. Temporal and spatial patterns of functional organization were detected in the community. In relation to the spatial organization, there were ethological and physical characteristics which promote the use of different environmental resources and, cosequently, favor the co-existence of the species in sympatry. In adults, the main differences referred to vocalizations with different physical attributes, use of distinct calling sites, and the preference for different oviposition sites. During larval development, there were differences in the micro-habitat occupied by each species as well as in the larval food, as verified in the gut contents. During the congregation for reproduction, social interactions were observed, ...Note: The complete abstract is available with the full electronic digital thesis or dissertations.
