HYPSIBOAS ALBOPUNCTATUS PDF

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.

Advertisement call duration was positively correlated and maximum frequency was negatively associated with air temperature, while call repetition rate and note duration had a positive correlation with body size and number of conspecific calling males, respectively Table 3.

We also investigated albopujctatus the presence of one species influences the spatial distribution or vocal behaviour of the other. The vocalizations studied here are formed by multipulsed notes with similar dominant frequencies and SPL; however, we found between species’ call differences’ that enable specific recognition. Our results highlight the importance of acoustic behavior in discriminating anuran species, demonstrating that vocalizations, and not calling sites, are the main mechanism allowing reproductive isolation during the breeding season in sympatric Hylidae species.
