The processing of spectral cues by the call analysis system of the tungara frog, Physalaemus pustulosus
Article Abstract:
An examination of female choice in the Neotropical frog Physalaemus pustulosus reveals that activation in a high-frequency region of the whine's fundamental between 900 and 560 Hz, followed by activation in a partially overlapping low frequency region between 640 and 500 Hz is essential and sufficient for call identification. The study compared full whines with modified whines and clicks. No one frequency or frequency band within each area is significant for identification and the identification system tolerates silent gaps and decreasing length of the signal.

Female preferences for temporal order of call components in the tungara frog: a Bayesian analysis
Article Abstract:
Female preferences for male Physalaemus pustulosus, Neotropical frog calls have been analyzed using Bayesian statistical methods. The males advertize their presence using a whine followed by 'chucks'. An analysis of different positions of the chuck in relation to the whine shows that this is important for species recognition. The females also have preferences for particular types of call in terms of their temporal relationship, and males have evolved calls that appeal to the females.

Plasticity in female mate choice associated with changing reproductive states
Article Abstract:
The plasticity in female mate choice that occurs over a range of timescales is examined over a course of a single breeding cycle using phonotaxis tests that assay acoustic-based mating preferences of female tungara frogs, Physalaemus pustulosus. Results suggests that the increase in permissive mate choice is due to a decrease in female choosiness, that is, a lowering of her threshold for accepting unattractive calls, as her receptivity increases.
