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.

Individuals appear to maintain a constant level of acoustic effort, but adjust their calls according to the social context Wells NewYork, Columbia University Press.

SPOTTED TREE-FROG Hyla albopunctata FAUNA PARAGUAY
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. Above audiospectrogram, below oscillogram. New York, Plenum Press. New York, John Wiley.
Animal Behaviour 76 5: Seewave, a free modular tool for sound analysis and synthesis. We measured the sound pressure level SPL of calls with a Minipa digital decibelimeter Type II; fast setting; A weighting at a 50 cm distance, oriented directly toward the calling male. All three calls had different structures and aggressive call I was the most emitted Table 2.
Means that the results of the search must include both words held together by an AND. In the literature, 0. 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. Synonymy by Tschudi,Classif.
Hypsiboas albipunctatus — Cope,J. In addition, these spectral parameters, similar to dominant frequency, are influenced by ‘the size of the males’ vocal cord and therefore are indicators of the males’ body size Ryan Allows a partial letter string albopunctatuss be entered and implies either no or various extension on this letter string.
The advertisement calls of the two frogs differ in their temporal structures and their aggressive calls had different maximum frequencies.
Neotropical Biology and Conservation
Power 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. The following acoustic parameters were measured: We also registered the number of calling males of both species in the site by acoustic identification and visual encounters.
Hypsiboas albopunctatus males, regardless of calling with or without 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 albopynctatus in sympatric Hylidae species. Means that the results of the search will all records that have either of the terms held together by an OR Lithobates OR “Costa Rica” Recovers all records that contain the word “Lithobates” or “Costa Rica”: The vocal repertoire of both anuran species studied here is slbopunctatus of advertisement and aggressive calls, as in other Neotropical species Heyer et al.
A taxon is Extinct EX when there is no reasonable doubt that the last individual has died. The reproductive biology of amphi bians. A factorial ANOVA was also used to test if perch height and distance to water differed between situations.

Bioacoustical studies are important to help to solve these puzzles.
