The vocal repertoire of both anuran species studied here is composed of advertisement and aggressive calls, as in other Neotropical species Heyer et albopuncctatus. Allows a partial letter string to be entered and implies either no or various extension on this letter string.

The calls emitted by H. The maximum frequency of the aggressive calls of H. We also investigated if the presence of one species influences the spatial distribution or vocal behaviour of the other.

Surveys should be over a time frame appropriate to the taxon’s life cycle and life form. Canadian Journal of Zoology 82 6: For each individual, we analyzed five advertisement and five aggressive calls.

Species categorized as Least Concern LC. Males emitted advertisement and aggressive calls Figs. Animal Behaviour 60 6: Journal of Biogeography 23 1: The digital readout of the SPL meter was observed visually during the recording time. Bulletin of the American Museum of Natural History Above audiospectrogram, below oscillogram.

Individuals appear to maintain a constant level of acoustic effort, but adjust their calls according to the social context Wells Vocalizations were recorded at sampling frequencies of 22 kHz and bit resolution wav files.

Regarding aggressive call I, the minimum frequency was negatively associated with body size and positively associated with air humidity, while SPL and calling rate were negatively associated with air temperature and positively associated with the number of conspecific calling males, respectively.

Hylidae closely related to H. Variations in the calling behavior of males and what drives these variations in both species is central to better understand the processes of specific recognition and female attraction.
