“…These parameters and intercall interval, call structure, and frequency modulation were used to distinguish the advertisement call of P. aguirrei from other species of the group. Table 3 summarizes these data, based on Barrio (1965), Bokermann (1966bBokermann ( , 1967, Heyer et al (1990), Cannatela et al (1998), Tárano (2001, and the present study. Data are preferentially presented as ranges.…”

“…Therefore, we analyzed six acoustic parameters for each adult male's call, with SVL, temperature, and humidity as covariates of each acoustic parameter: call duration (measured at 0 amplitude on the oscillogram); call rate [(total number of calls -1) / the time from the beginning of the first call to the beginning of the last call]; rise time (time from call onset to the peak amplitude in the oscillogram); dominant frequency (frequency of the maximum energy on the spectrogram); frequency modulation (frequency range between the onset and offset of the dominant harmonic in the call spectrogram); and pulse rate [(total number of pulses − 1) / time from the beginning of the first pulse to the beginning of the last pulse] (Cocroft and Ryan 1995;Tárano 2001;Ryan and Rand 2003;Briggs 2010;Rodríguez et al 2010).…”

Background: We examined differences in reproductive activities and intraspecific variations in advertisement calls of Duttaphrynus melanostictus (Schneider, 1799) that lives in a tropical region of central Vietnam. The snout-vent length (SVL) of sexually mature males ranged from 50.2 to 70.3 mm, while that of females ranged from 65.2 to 97.3 mm. Histological analyses of testes revealed that sperm was not present throughout the year, indicating discontinuous reproductive activity for adult males. Adult females were captured year-round, but reproductive females were observed only during months of the auxiliary rainy season (mainly April to July), indicating that females reproduce seasonally. We also estimated levels of within-male variation of each call property and the influences of the ambient temperature, humidity, and the SVL of calling males on acoustic features. Results: The call rate and pulse rate showed intermediate levels of variation, whereas the dominant frequency and call duration were the most stereotyped properties. One-way analyses of variance for six acoustic properties showed that the call rate, pulse rate, and rise time significantly differed (p < 0.05) among localities. Advertisement calls were a series of groups of 56 to 244 (145 ± 54) pulses with an average call duration of 26.722 s, an average pulse rate of 11.69 pulses/s, and an average dominant frequency of 1.293 kHz. The results of the multiple regressions for possible effects of temperature, humidity, and SVL on the six acoustic properties indicated that the dominant frequency, pulse rate, call duration, and rise time were positively significant. Conclusions:In Bach Ma National Park, when air temperature in the recording area decreased to <16.6°C, and advertisement calls of adult males virtually ceased in all three populations.

“…For animals that use acoustic display, variation in the advertisement call provides material for both intrasexual and intersexual selection (Darwin 1981, Alexander 1962, Forrest & Green 1991, and selective pressures originating from interspecific predation may also serve to influence various aspects of the display (Alexander 1962, Andersson 1994, Bertram et al 2004. Additionally, the morphology of the caller should influence aspects of an acoustic advertisement signal (Brown et al 1996, Gray 1997, Bennet-Clark 1998, Tarano 2001, Burmeister et al 2002, Esteban et al 2002, Lode & Jacques 2003, Gerhardt 2005.…”

“…Males produce a long sequence of brief harmonic chirps varying from 1.7 to 2.9 s -1 at a carrier frequency of about 2.0 kHz (Walker & Figg 1990, Hill 2000. Male-male spacing within the lek is thought to be a function of substrate-borne vibration (Hill & Shadley 1997, 2001). Females fly above an aggregation of calling males, drop to the ground and enter a male's burrow (Walker & Figg 1990, Hill 1999.…”
