Abstract

Vocalizations of a population of Leptodactylus natalensis were monitored in a temporary pond from November 2002 to October 2004. This pond is located in a fragment of Atlantic rainforest belonging to the private Ecologic Refuge Charles Darwin, in the city of Igarassu, state of Pernambuco, Brazil. Individuals were active during most of the studied months, with peaks of activity during dry season. Vocal activity was recorded both in day and nighttime. There was a significant negative effect of temperature on vocal activity. The number of individuals vocalizing was not affected significantly by rainfall, but it was by the number of females on the environment. A great plasticity of vocal activities of L. natalensis was verified, both in season and turn.
