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.

Bioacoustics is the main form of communication in anurans, and is one of the best ways to discriminate among species. 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.

Body size positively influenced other call parameters of H. Hylidae closely related to H. Tests for correlation and regression analyses. Recovers only records that contain the word Lithobates AND “Costa Rica”, but excludes any record that contains the word “forreri” in any part of the record: Boletim do Museu Nacional Ecology and natural history of a neotropical savanna.

Species categorized as Endangered EN. Acoustic communication in two species of the Hypsiboas albopunctatus group Anura: 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 albopunctatsu of conspecific calling males, respectively Table 3.



Surveys should be over a time frame appropriate to the taxon’s life cycle and life form. Hylidae in sympatry and allopatry. We arrived at this conclusion based on the context of emissions and temporal structure of calls, as suggested by Wells New York, John Wiley and Sons.

Bypsiboas may also increase note duration, repetition rate and maximum frequency according to an increase in the SPL of other males.

Means that the results of the search will all records that have either of the terms held together by an OR. Wells Hypslboas The effect of social interactions on anuran vocal behavior, p. Post-hoc power analysis revealed that statistical power to detect the relationships between acoustic parameters and morphological and environmental parameters were, in general, high for both species Table 3.

Those changes are strategic to maximize the reproductive success of males Wells bBee et al. We recorded the calls of 37 males of H. After each recording, we measured the snout-vent length SVL of males to the nearest 0.
