Evoked vocal responses of male frogs Batrachyla taeniata to synthetic advertisement calls and variants having different temporal features altered parametrically were studied to identify patterns of evoked vocal responses ...

Relationships between testosterone plasma levels and evoked vocal responses of males of the leptodactylid frog Batrachyla taeniata from southern Chile were studied. Evoked vocal responses were elicited in the field with ...

Degradation phenomena affecting animal acoustic signals may provide cues to assess the distance of emitters. Recognition of degraded signals has been extensively demonstrated in birds, and recently studies have also reported ...

Localization of a sound source is important for animals in mating contexts: females generally orient towards signalling males, and males can estimate the position and quality of potential rivals. In anurans, the effect of ...

Animals that communicate by means of acoustic signals show diverse strategies in the presence of noise interference. Penna et al. (2005, Animal Behaviour, 70, 639e651) found that the leptodactylid frog Eupsophus calcaratus ...
