Summary1.Four hundred and ninety-nine females ofHyla cinerea made 820 responses in two-choice playback experiments conducted at sound pressure levels (SPL's) between 48 and 85 dB. About one-third of the animals responded at 48 dB, and the percentage increased as a function of SPL.2.Females did not show a preference for a standard synthetic call with two components (0.9 + 3.0 kHz) of equal relative amplitude over a single-component (0.9 kHz) call at 48 dB SPL, but chose the bimodal stimulus at… Expand

TLDR
Although a bimodal spectrum (greatly attenuated second harmonic) is typical of the mating call of H. gratiosa, females did not show a preference for a call of 0.50 + 2.00 kHz over one of 1.00 + 1.50 kHz, and discriminated against signals with high-frequency attenuation only at moderate to high sound pressure levels.

Mid-frequency suppression in the green treefrog (Hyla cinerea): mechanisms and implications for the evolution of acoustic communication
TLDR
Previous speculation that mid-frequency suppression evolved to enhance species discrimination is probably incorrect, because this phenomenon is more likely to reflect a general sensory bias in anurans and other vertebrates, tone-on-tone inhibition. Expand
Acoustic spectral preferences in two cryptic species of grey treefrogs: implications for mate choice and sensory mechanisms
TLDR
Females of both species preferred calls with both spectral peaks to calls with a single, high- frequencies peak, even when the low-frequency peak was attenuated by 24–30 dB, serving to emphasize that typically subdominant frequency components can have seemingly disproportionate effects on signal attractiveness. Expand
Phonotactic selectivity in two cryptic species of gray treefrogs: effects of differences in pulse rate, carrier frequency and playback level
TLDR
The two main spectral components of the advertisement calls of two species of North American gray treefrogs overlap broadly in frequency, and the frequency of each component matches the sensitivity of one of the two different auditory inner ear organs. Expand
Female green treefrogs (Hyla cinerea) do not selectively respond to signals with a harmonic structure in noise
TLDR
This study used the same two-component stimuli to test the prediction that gravid females would better detect harmonic sounds in noise than inharmonic ones, and offered gravid treefrogs simultaneous choices between alternative two- component synthetic sounds. Expand
Phonotactic selectivity in two cryptic species of gray treefrogs: effects of differences in pulse rate, carrier frequency and playback level.
TLDR
Standard synthetic calls with one of these spectral peaks and the pulse rate typical of conspecific calls were tested against synthetic alternatives that had the same spectral peak but a different pulse rate, and greater pulse-rate selectivity was usually observed when the low-frequency rather than the high-frequency peak was used.

Preferences based on spectral differences in acoustic signals in four species of treefrogs (Anura: Hylidae)
TLDR
Non-linear effects indicate that there is an increasing influence of high-frequency energy on preferences as females approach calling males, and serve to emphasize that playback experiments conducted at a single level may have limited generality. 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

Auditory masking and effects of noise on responses of the green treefrog (Hyla cinerea) to synthetic mating calls
TLDR
Female green treefrogs are attracted to a sound source which broadcasts appropriate synthetic mating calls and sounds processed by both auditory organs in the treefrog can be analyzed in CR-bands that are sufficiently narrow to resolve the harmonic structure of a typical mating call. Expand
MATING CALL RECOGNITION IN THE GREEN TREEFROG {HYLA CINEREA): THE SIGNIFICANCE OF SOME FINE-TEMPORAL PROPERTIES
TLDR
The results of four experiments indicated that periodicity preferences depended on corresponding changes in the amplitude-time envelopes of the signals, which had biological significance in species recognition and in the differentiation of the mating call from other signals in the repertoire of the green treefrog. Expand
Temperature effects on frequency preferences and mating call frequencies in the green treefrog,Hyla cinerea (Anura: Hylidae)
TLDR
The results indicate, however, that resonance properties of the buccal cavity alone are not sufficient to match the mating call frequencies with the frequency sensitivity of the auditory system, and this area is involved in processing biologically significant sounds. Expand
Significance of two frequency bands in long distance vocal communication in the green treefrog
TLDR
It was found that a low frequency component of the call was more attractive to females than were high frequency components, and in discrimination experiments females detected attenuation of a 3-kHz component relative to a 0.9- kHz component at moderate to high SPL but failed to do so at low SPL.

1. Synthetic calls with a waveform periodicity of 300/sec and a bimodal spectrum attracted female green treefrogs as effectively as natural calls. 2. Effectiveness was markedly reduced if theExpand
Accuracy of phonotaxis by the green treefrog (Hyla cinerea)
TLDR
It is suggested that the treefrog's ear must act as a sound pressure gradient receiver, and the high frequency components around 3 kHz, normally found in the mating call, do not enhance the accuracy of sound localization. Expand
Behavioral Isolating Mechanisms of the Treefrogs Hyla cinerea and H. gratiosa
TLDR
Analysis of the spectra of the calls of the two broadly sympatric, interfertile treefrogs differ significantly from those previously published in that two distinct spectral peaks are found and are important for call recognition by female frogs. Expand

The Vocalizations of Some Hybrid Treefrogs: Acoustic and Behavioral Analyses
TLDR
The vocalizations of natural hybrids between various species of treefrogs (Hylidae) are compared and the closer the spectrum of a natural call resembled that of conspecific calls, the more attractive was the acoustic signal. Expand

TLDR
By selectively sectioning and recording from individual nerve branchlets within the inner ear, it is shown that the amphibian papilla gives rise to low and mid-frequency sensitive units and the basilar papilla give rise to high-frequencysensitive units. Expand
