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.

Hypsiboas boans — Tschudi,Classif. Maximum frequency and calling rate of the advertisement call were positively associated with the number of calling males of the same species Table 3. Brenowitz EA Neighbor call amplitude influences aggressive behavior and intermale spacing in choruses of the pacific treefrog Hyla regilla.

Neotropical Biology and Conservation

Animal Behaviour 60 6: Usually, this relationship with morphology is found for the dominant frequency albopuunctatus. Leptodactylidae from Central Brazil. We also registered the number of calling males of both species in the site by acoustic identification and visual encounters.

Vocalizations were recorded at sampling frequencies of 22 kHz and bit resolution wav files. Boana albopunctata Spix, Class: Hypsiboas paranaiba males emitted aggressive calls I with a higher calling rate than H. 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.

Our results demonstrated that some call parameters of both species were associated with environmental and morphological variables. Boletim do Museu Nacional In the present study we examined the effect albopuncctatus environmental air temperature and humidity and morphological body size attributes on the acoustic parameters of two frogs of the Hypsiboas albopunctatus species group H.

This similarity may be the result of the close phylogenetic relationship between the species Faivovich et al.

South American Journal of Herpetology 7 2: This is an open-access article distributed under the terms of the Creative Commons Attribution License. We did not include aggressive call II in the analysis because only a few individuals emitted this call. We are not responsible for their content.

Error for Hypsiboas albopunctatus. 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. Ecology and natural history of a neotropical savanna.

We recorded 24 males of H. NewYork, Columbia University Press. Thomas L, Juanes F The importance of statistical power analysis: Tropical anuran communities are very diverse.

Cruz, Feio, and Caramaschi,Anf. R Development Core Team The following acoustic parameters were measured: The advertisement calls of Hypsiboas albopunctatus analyzed are similar to those described by Heyer et al.

Bioacoustical studies are important to help to solve these puzzles. A taxon is Endangered EN when the best available evidence indicates that it meets any of the criteria A to E for Endangered, and it is therefore considered to be facing a very high risk of extinction in the wild.

Journal of Natural History 41 We used power tests to determine if our sampling protocol and analytical framework enable us to test our working hypothesis Faul et al. Blog Log of changes and additions, How to cite How to use History of the project Comments on version 5. All three calls had different structures and aggressive call I was the most emitted Table 2.

A taxon is Near Threatened NT when it has been evaluated against the criteria but does not qualify for Critically EndangeredEndangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened category in the near future. We need to more than double the number of wild species plants, animals and fungi assessed Our new goal isspecies by The maximum frequency of the aggressive calls of H.
