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.

Herpetological Journal 22 4: We believe that the values observed in the power analysis in this study are high albopumctatus to detect biologically significant effects, despite the fact that some few values are below hypsiboa. As a consequence ectothermy,’the metabolic efficiency of amphibians improve with increasing temperature Wellsas seen for the duration of the advertisement call of H. Auletris boans — Wagler,Nat. Our results demonstrated that some call parameters of both species were associated with environmental and morphological variables.

SVL and the body masses of the males were Air temperature and humidity were obtained with a digital thermo-hygrometer to the nearest 0.

Strabomantidae in Central Brazil. To hypsibpas if the species’ calls differed between situations calling alone or in the presence of the other specieswe performed factorial analysis of variance ANOVA with albopunctafus of multiple regressions to control for the effects of the variables mentioned above.

Means that the results of the search will all records that have either of the terms held together by an OR.

We analyzed the temporal and spectral parameters of calls with Avisoft-Sonagraphy lite r and Cool Edit 96 r software, respectively. Brain, Behavior and Evolution 28 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.


Bosch J, Marquez R Discriminant functions for the sex identification in two midwife toads Alytes obstetricans and A.

The Hypsiboas albopunctatus species group comprises 10 species, nine of which are defined based on molecular characters Faivovich et al. After each recording, we measured the snout-vent length SVL of males to the nearest 0. Synonymy by Tschudi,Classif.

News from IUCN

We arrived at this conclusion based on the context of emissions and temporal structure of calls, as suggested by Wells Regarding aggressive call I, the minimum frequency was negatively associated hypsiboaas body size and positively associated with air humidity, while SPL and calling rate were negatively associated with air temperature and positively associated with albpounctatus number of conspecific calling males, respectively.

Hyla albopunctata Spix,Animal. Hillsdale, Lawrence Erlbaum, 2nd ed. This similarity may be the result of the close phylogenetic relationship between the species Faivovich et al. Ptacek MB Calling sites used by male gray treefrogs, Hyla versicolor and Hyla chrysoscelisin sympatry and allopatry in Missouri.

Leptodactylinae in the Cerrado of central Brazil. We did not include aggressive call II in the analysis because only a few individuals emitted gypsiboas call.

The most common vocalization of H. Canelas and Bertoluci,Iheringia, Zool. Eastern Gorilla Critically Endangered, A4bcd ver 3. Animal Behaviour 76 5: Bioacoustical studies are important to help to solve these puzzles. The types of perch, perch height and distance from the calling male to the water were similar in both species. The aggressive calls are similar to those described by Heyer et al.

The mean distance from the water was 0. Sound figures were obtained using Seewave package version 1.


A taxon is Vulnerable VU when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable, and it is therefore considered to be facing a high risk of extinction in the wild. Animal Behaviour 47 3: We need to more than double the number of wild species plants, animals and fungi assessed Our new goal isspecies by Maximum frequency and calling rate of the advertisement call were positively associated with the number of calling males of the same species Table 3.


Species categorized as Extinct EX. The maximum frequency of the aggressive calls of H.

Boana albopunctata – Wikipédia, a enciclopédia livre

In the present study we examined the effect of environmental air temperature and humidity and morphological body size attributes on the acoustic parameters of two frogs of the Hypsiboas albopunctatus species group H. Bulletin of the American Museum of Natural History Electronic database available online at: Will find all uses of “. 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.

Allows a partial letter string to be entered and implies either no or various extension on this letter string. Animal Behaviour 36 6: Schwartz JJ Call monitoring and interactive playback system in the study of acoustic interactions, p. This is only achievable with support from people like you. Error for Hypsiboas albopunctatus. Calamita fasciatus Schneider,Hist. Although not typical, this behavior is also found in other anuran species – e.

The digital readout of the SPL meter was observed visually during the recording time. To prevent such interference, males may choose vocalization sites that promote spatial segregation PtacekMartins et al.

Hypsiboaa analysis can be used to point out whether an experiment had a good chance of detecting biologically significant differences in populations with statistically significant results.
