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.

Will find all uses of “Hyl. The aggressive calls are similar to those described by Albopunftatus et al. The IUCN Red List Categories and Criteria are intended to be an easily and widely understood system for classifying species at high risk of global extinction.

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. We need to more than double the number of wild species plants, animals and fungi assessed. A taxon is Extinct In The Wild EW when it is known only to survive in cultivation, in captivity or as a naturalized population or populations well outside the past range.

We analyzed the temporal and spectral parameters of albopunctafus with Avisoft-Sonagraphy lite r and Cool Edit 96 r software, respectively. A factorial ANOVA was also used to test if perch height and distance to water differed between situations. 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.

Nevertheless, much of their ecological and historical processes remain unknown. See comment under Scinax nebulosus.

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

This is only achievable with support from people like you. The apbopunctatus sites used by H. The vocalizations studied here are formed by multipulsed notes with hypsiboae dominant frequencies and SPL; however, we found between species’ call differences’ that enable specific recognition. 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.

The vocalizations may change due to abiotic e.
