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.

See comment under Scinax nebulosus. Species categorized as Extinct EX. A language and environment for statistical computing. Bioacoustical studies are important to help to solve these puzzles.

The aggressive calls are similar to those described by Heyer et al. We need to more than double the number of wild species plants, animals and fungi assessed Our new goal isspecies by Sound figures were obtained using Seewave package version 1. We also registered the number of calling males of both species in the site by acoustic identification and visual encounters. Far more than a list of species and their status, it is a powerful tool to inform and catalyze action for biodiversity conservation and policy change, critical to protecting the natural resources we need to survive.

A factorial ANOVA was also used to test if perch height and distance to water differed between situations. Animal Behaviour 52 4: According to Rodriguez et al.

To test if the species’ calls differed between situations calling alone or in the presence of the other specieswe performed factorial analysis of variance ANOVA with residuals of multiple regressions to control for the effects of the variables mentioned above. Maximum frequency and calling rate of the advertisement call were positively associated with the number of calling males of the same species Table 3.

Herpetological Albopunchatus 21 1: Males kept a mean distance of 0. The advertisement calls of the two frogs differ in their temporal structures and their aggressive calls had different maximum frequencies.

Means that the results of the search will all records that have either of allbopunctatus terms held together by an OR Lithobates OR “Costa Rica” Recovers all records that contain the word “Lithobates” or “Costa Rica”: Males emitted three types of vocalization: Synonymy by Tschudi,Classif.

The vocal repertoire of both anuran species studied here is composed of advertisement and aggressive calls, as in other Neotropical species Heyer et al.

The acoustic behavior of both species was influenced by the number of conspecifics calling at the site, as reported for other anurans e.
