Advertisement calls, auditory tuning, and larynx and ear morphology were examined in 3 neotropical frogs, Hyla microcephala, H. phlebodes and H. ebraccata, H. microcephala has the highest call dominant frequency (6.068 kHz) and basilar papilla tuning (5.36 kHz). H. phlebodes and H. ebraccata calls have lower dominant frequencies (3.832 and 3.197 kHz respectively) and basilar papilla tuning (2.79 and 2.56 kHz). The primary call notes of H. ebraccata are longer (181.6 ms) than those of H… Expand
Auditory matching of male Epipedobates femoralis (Anura: Dendrobatidae) under field conditions
TLDR
Frequency tuning interacts with temporal call features in maximizing the detection of conspecific signals and reducing the probability of heterospecific interference under field conditions are suggested. Expand
Geographic variation in the laryngeal morphology of a widely distributed South-American anuran: behavioural and evolutionary implications
TLDR
Important geographic variation in laryngeal morphology is shown, which is in correspondence with acoustic, behavioural and genetic variation in this species. Expand
Auditory brainstem responses in Cope’s gray treefrog (Hyla chrysoscelis): effects of frequency, level, sex and size
TLDR
Frequency-dependent differences in ABRs were correlated with expected differences in the tuning of two sensory end organs in the anuran inner ear (the amphibian and basilar papillae). Expand
Multimodal signaling in the Small Torrent Frog (Micrixalus saxicola) in a complex acoustic environment
TLDR
It is suggested that the vocal sac acts as a visual cue and improves detection and discrimination of acoustic signals by making them more salient to receivers amidst complex biotic background noise. Expand
AUDITORY TUNING OF THE IBERIAN MIDWIFE TOAD , ALYTES CISTERNASII
The studyofauditorytuning in anuran amphibians is useful for understanding their reproductive behaviour. Auditory tuning is known for a relatively large number of anuran species but most of thoseExpand
THERMAL DEPENDENCY OF CALLING PERFORMANCE IN THE EURYTHERMIC FROG COLOSTETHUS SUBPUNCTATUS
TLDR
This study tested the hypothesis that eurythermy is associated with thermal independence of behavioral performance in C. subpunctatus and found that most temporal parameters were indeed affected by temperature, although thermal sensitivity was low. Expand
Does sexual dimorphism vary by population? Laryngeal and ear anatomy in cricket frogs
TLDR
The results suggest that in anurans, selection for changes in body and head size affects both sexes equally, male calls and the vocal structures responsible for them can further diversify without concordant changes in females. Expand
01. Comparison of female and male vocalisation and larynx morphology in the size dimorphic foot-flagging frog species Staurois guttatus
TLDR
It is argued that in noisy environments such as streams, small male larynx size associated with high frequency calls is advantageous due to reduced masking and discussed the functional differences and communalities in signalling behaviour between the sexes and in the genus Staurois. Expand
Seasonal Plasticity of Peripheral Auditory Frequency Sensitivity
TLDR
This first demonstration of a natural cyclicity in peripheral auditory frequency sensitivity among vertebrates may represent an adaptive plasticity of the female midshipman's auditory system to enhance the acquisition of auditory information needed for mate identification and localization during the breeding season. Expand
Decoupled Evolution between Senders and Receivers in the Neotropical Allobates femoralis Frog Complex
TLDR
Evidence from phylogenetic comparative methods supports the hypothesis of decoupled evolution between sender and receiver in the male-male communication system of the A. femoralis complex, where signal recognition appears to evolve more slowly than the calls. Expand

Interspecific acoustic interactions of the neotropical treefrog Hyla ebraccata
TLDR
The results demonstrate that H. ebraccata males behave in ways which enhance their ability to communicate in a noisy assemblage of conspecific and heterospecific males. Expand
An experimental study of acoustic interference between two species of neotropical treefrogs
TLDR
It is demonstrated that background noise generated by H. microcephala choruses causes a shift in the timing and type of calls given by nearby H. ebraccata, and vocal interactions in mixed species anuran choruse may have important effects on the calling behaviour of individual males. Expand
Acoustic communication in spring peepers
TLDR
The electrophysiological results show two populations of auditory fibers in the VIIIth nerve with characteristics similar to those in other anurans, and a sexual dimorphism is apparent in the tuning of BP units. Expand
Species specificity and temperature dependency of temporal processing by the auditory midbrain of two species of treefrogs
TLDR
The temporal selectivities of AM band-suppression neurons were found to be temperature dependent and the modulation rate at which a response minimum was observed shifted to higher values as the temperature was elevated, extending earlier findings of temperature-dependent temporal selectivity in the gray treefrog.

Vocal communication in a neotropical treefrog, Hyla ebraccata: Advertisement calls
TLDR
The results indicate that male H. ebraccata respond to other males in a chorus in ways which enhance their ability to attract mates. Expand
Call patterns and basilar papilla tuning in cricket frogs. I. Differences among populations and between sexes.
TLDR
Male cricket frogs (Acris crepitans) produce a broad-band, high frequency advertisement call with a single spectral peak (the dominant frequency), and changes in dominant frequency in a population coincided with changes in tuning of both male and female basilar papillae. Expand
Calling energetics of a neotropical treefrog, Hyla microcephala
TLDR
Male H. microcephala appear to conserve energy by reducing calling rates when only a few males are active and increasing calling efforts only when vocal competition among males is intense. Expand
Intensity discrimination and the precision of call timing in two species of neotropical treefrogs
TLDR
The ability of frogs to call preferentially during very brief silent periods or during periods of slight intensity reductions is viewed as an adaptation for avoiding acoustic interference, and thus improves the efficiency of acoustic communication in an intense and complex sonic environment. Expand
The importance of spectral and temporal properties in species and call recognition in a neotropical treefrog with a complex vocal repertoire
TLDR
Hyla microcephala males can continue to give calls which will attract females even during aggressive interactions, and spectral cues are also sufficient for species discrimination, but temporal information may be more important. Expand
Vocal morphology of the Physalaemus pustulosus species group (Leptodactylidae): morphological response to sexual selection for complex calls
TLDR
The morphological changes responsible for the evolution of this unusual behavioural innovation, the complex call, are gradual, and almost trival, in nature. Expand
