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.

This highlights the importance of considering different call parameters in bioacoustical studies. Hypsiboas albipunctatus — Cope,J.

The mean SVL and body mass of the individuals were, respectively, The aggressive calls are similar to those described by Heyer et al. Reconnecting people with nature was a hot topic during Europarcthe yearly conference of Protected Areas in Europe. Synonymy by Bokermann,Rev.

Spotted Treefrog Frank and Ramus,Compl. A taxon is Extinct EX when there is no reasonable doubt that the last individual has died. Animal Behaviour 36 6: Behavioral Ecology 11 2: We used multiple regression analysis to test if air temperature, air humidity, body size value obtained by multiplying the SVL by the body mass and number of calling males of both species influenced the acoustic parameters. However, our work is nowhere near complete. The following acoustic parameters were measured: Comparing the calling sites chosen by males of Albopunctwtus.

Neotropical Biology and Conservation

The acoustic behavior of both species was influenced by the number of conspecifics calling at the site, as reported for other anurans e. Brenowitz EA Neighbor call amplitude influences aggressive behavior and hypsiboass spacing in choruses of the pacific treefrog Hyla regilla.


Nevertheless, much of their ecological and historical processes remain unknown.

New Jersey, Prentice-Hall, 4th ed. Error for Hypsiboas albopunctatus. We also registered the number of calling males of both species in the site by acoustic identification and visual encounters. 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.

This signal may be used by other males to assess ‘the fighting ability of an opponent and by females to evaluate which males are larger and better breeding partners Bee et al.

Ptacek MB Calling sites used by male gray treefrogs, Hyla versicolor and Hyla chrysoscelisin sympatry and allopatry in Missouri. Species categorized as Hypsiobas VU. The advertisement calls of the two frogs differ in their temporal structures and their aggressive calls had different maximum frequencies.
