Abstract. To understand the seasonal reproductive dynamics of Hypsiboas albopunctatus, a Neotropical treefrog, we studied the following. Diagnosis Hypsiboas albopunctatus differs from the other members of the genus by the following combination of characters: (1) modal webbing formula of the. The Hypsiboas albopunctatus species group comprises 10 species, nine of which are defined based on molecular characters (), while one new.

On the other hand, as found for’ the SPL aggressive call of H. Tropical anuran communities are very diverse.

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.
Neotropical Biology and Conservation
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.
We used power tests to determine if our sampling protocol and analytical framework enable us to test our working hypothesis Faul et al. Error for Hypsiboas albopunctatus.
Proceedings of the National Academy of Sciences Suppl. Bosch J, Alvopunctatus R Discriminant functions for the sex identification in two midwife toads Alytes obstetricans and A. Animal Behaviour 57 6: SVL and the body masses of the males were Please enter your e-mail address and password below. Body size positively influenced other call parameters of H. 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.
R Development Core Team The types of perch, perch height and distance from the calling male to the water were similar in both species. Species categorized as Extinct EX.
