“…Equation (1.3) is consistent with the data showing that call rates are governed by the rates of activity that produce the sound (e.g. wing closure rates), which in turn are governed by muscle contraction rates (Josephson 1973;Schneider 1977;Brozovich & Pollack 1983;Mitchell et al 2008) and ultimately metabolic rate (e.g. Pough et al 1992;Bailey et al 1993).…”

Animals produce a tremendous diversity of sounds for communication to perform life's basic functions, from courtship and parental care to defence and foraging. Explaining this diversity in sound production is important for understanding the ecology, evolution and behaviour of species. Here, we present a theory of acoustic communication that shows that much of the heterogeneity in animal vocal signals can be explained based on the energetic constraints of sound production. The models presented here yield quantitative predictions on key features of acoustic signals, including the frequency, power and duration of signals. Predictions are supported with data from nearly 500 diverse species (e.g. insects, fishes, reptiles, amphibians, birds and mammals). These results indicate that, for all species, acoustic communication is primarily controlled by individual metabolism such that call features vary predictably with body size and temperature. These results also provide insights regarding the common energetic and neuromuscular constraints on sound production, and the ecological and evolutionary consequences of producing these sounds.

“…Given that amphibian anurans are ectothermic, their body temperature is heavily influenced by environmental temperature, with effects on behaviour and physiology (Wells 2007). In this study, the acoustic variables that were correlated with the water temperature are the variables whose emissions depend on laryngeal muscles (Schmidt 1965, Martin and Gans 1972, Schneider 1977, Schneider 1988, Pough et al 1992. In hylids, which have calls consisting of a series of repeated pulses, laryngeal muscles actively open and close the larynx in synchrony with trunk muscles to produce the highly stereotyped and regularly spaced pulses which often are important for species recognition (Gerhardt 1991, Girgenrath andMarsh 1997).…”

Temperature effect on the advertisement call of Pleurodema tucumanum (Anura: Leiuperidae). The advertisement call represents an important character to discriminate species, mainly between sibling species. The genus Pleurodema has cryptic species, therefore its acoustical characteristics could represent an useful tool to solve taxonomic problems. It is expected that the advertisement call acoustic properties of the amphibian anurans will vary with the temperature because the frogs are ectotherms. We evaluated the effect of temperature in the acoustic variables of the advertisement call of Pleurodema tucumanum. The inter-call interval, number of pulses per call, inter-pulse interval and pulse rate showed covariation with temperature, whereas the call duration, pulse duration and dominant frequency were temperature-independent. The advertisement call of P. tucumanum corresponds to a single periodic pulse train. The call showed an average duration of 289 ms, dominant frequency of 2552 Hz and 35 pulses of 2.38 ms at 22˚C. The number of pulses increased with temperature. The discrimination of exogenous variability from the acoustic components allows one to analyze the intrinsic variability of the advertisement calls.Keywords: bioacoustic analysis, linear regression model, single periodic pulse train.

“…Por lo tanto, como estos organismos son ectotermos, las propiedades acústicas de sus cantos son afectadas por la temperatura en la cual se producen dichas emisiones. Las variables acústicas que se correlacionaron con la temperatura del agua son aquellas variables cuyas emisiones dependen de los músculos del tronco y músculos laríngeos (Schmidt 1965, Martin & Gans 1972, Schneider 1977, Schneider 1988, Pough et al 1992. En los hílidos, los cuales tienen cantos constituidos de una serie de pulsos repetidos, los músculos laríngeos abren y cierran la laringe en sincronía con los músculos del tronco para producir los pulsos regularmente espaciados que resultan importantes en el reconocimiento específico (Gerhardt 1991, Girgenrath & Marsh 1997.…”

Bioacoustic of the advertisement call of Ceratophrys cranwelli (Anura: Ceratophryidae). The advertisement call plays an important role in the life history of anuran amphibians, mainly during the breeding season. Call features represent an important character to discriminate species, and sound emissions are very effective to assure or reinforce genetic incompatibility, especially in the case of sibling species. Since frogs are ectotherms, acoustic properties of their calls will vary with temperature. In this study, we described the advertisement call of C. cranwelli, quantifying the temperature effect on its components. The acoustic emissions were recorded during 2007 using a DAT record Sony™ TCD-100 with stereo microphone ECM-MS907 Sony™ and tape TDK™ DAT-RGX 60. As males emit their calls floating in temporary ponds, water temperatures were registered after recording the advertisement calls with a digital thermometer TES 1 300±0.1°C. Altogether, 54 calls from 18 males were analyzed. The temporal variables of each advertisement call were measured using oscillograms and sonograms and the analyses of dominant frequency were performed using a spectrogram. Multiple correlation analysis was used to identify the temperature-dependent acoustic variables and the temperature effect on these variables was quantified using linear regression models. The advertisement call of C. cranwelli consists of a single pulse group. Call duration, Pulse duration and Pulse interval decreased with the temperature, whereas the Pulse rate increased with temperature. The temperature-dependent variables were standardized at 25°C according to the linear regression model obtained. The acoustic variables that were correlated with the temperature are the variables which emissions depend on laryngeal muscles and the temperature constraints the contractile properties of muscles. Our results indicated that temperature explains an important fraction of the variability in some acoustic variables (79% in the Pulse rate), and demonstrated the importance of considering the effect of temperature in acoustic components. The results suggest that acoustic variables show geographic variation to compare data with previous works. Rev. Biol. Trop. 61 (1): 273-280. Epub 2013 March 01.
