“…However, the call duration and note number were higher in the study by Wang et al (2014) than in our data, suggesting geographic variation in some acoustic parameters among different populations. Similar patterns have been reported in other anuran species including Bufo melanostictus (Wei et al 2012), Hypsiboas cordobae (Baraquet et al 2015), and Paa spinosa (Shen et al 2015). The dominant frequency was similar between our study and that of Wang et al (2014), indicating that this stable acoustic parameter can be used to distinguish the species of Xenophrys (Wang et al 2014).…”

“…Given the species-specific properties of anuran advertisement calls, they have been used as a diagnostic tool to resolve taxonomic problems (Wang et al 2014;Twomey et al 2015;Galvis et al 2016;Rivera-Correa et al 2017). Because advertisement calls are distinctive, they are also of widespread interest in studies of phylogeography (Baraquet et al 2015;Shen et al 2015;Lee et al 2016;Forti et al 2016) and evolution (Brusa et al 2013;Kaefer et al 2013). However, the characteristics of advertisement calls are easily influenced by biotic and abiotic factors such as air temperature, body temperature, body size and weight, and social context (Gingras et al 2013a, b;Toledo et al 2015).…”

“…Other biotic processes, like interspecific acoustic interactions, which generate distinctive background noise, can affect call variation among populations (Höbel and Gerhardt 2003;Booman and Kurniati 2011;Xiong et al 2015). Therefore, sexual selection and environmental conditions may result in variation in advertisement call characteristics among individuals and populations (Shen et al 2015;Forti et al 2016;Lee et al 2016;Bosch et al 2017).…”

The characteristics of male anurans' calls play an important role in mating success during the breeding season. In this study, we analyzed intra-and inter-individual variability of the advertisement calls of the pale-shouldered horned toad (Xenophrys boettgeri) in the field during its breeding season in Lishui, Zhejiang Province, China. The results showed that some acoustic parameters were significantly correlated with morphological features and air temperature. Most acoustic parameters including note numbers, call duration, and dominant frequency were static, whereas the call interval was intermediate. The CV b /CV w ratio was greater than 1.0 for all acoustic parameters analyzed, with between-individual variation being higher than within-individual variation. Furthermore, the acoustic parameter results of principle component analysis and discriminant function analysis indicated that note numbers and call interval are potentially useful for individual discrimination of X. boettgeri.

“…Here, we only considered two call traits, call duration and dominant frequency, because they were used in nearly all of the studies. Some studies mentioned in the text were re-analyzed (Faria et al 2013) or excluded from this summary because no populationlevel data were presented by the authors (e.g., ) or because it was not possible to eliminate data from heterospecific populations (e.g., Lougheed et al 2006;Simões et al 2008;Amézquita et al 2009;Shen et al 2015).

Vocalizations of anuran amphibians have received much attention in studies of behavioral ecology and physiology, but also provide informative characters for identifying and delimiting species. We here review the terminology and variation of frog calls from a perspective of integrative taxonomy, and provide hands-on protocols for recording, analyzing, comparing, interpreting and describing these sounds. Our focus is on advertisement calls, which serve as premating isolation mechanisms and, therefore, convey important taxonomic information. We provide recommendations for terminology of frog vocalizations, with call, note and pulse being the fundamental subunits to be used in descriptions and comparisons. However, due to the complexity and diversity of these signals, an unequivocal application of the terms call and note can be challenging. We therefore provide two coherent concepts that either follow a note-centered approach (defining uninterrupted units of sound as notes, and their entirety as call) or a call-centered approach (defining uninterrupted units as call whenever they are separated by long silent intervals) in terminology. Based on surveys of literature, we show that numerous call traits can be highly variable within and between individuals of one species. Despite idiosyncrasies of species and higher taxa, the duration of calls or notes, pulse rate within notes, and number of pulses per note appear to be more static within individuals and somewhat less affected by temperature. Therefore, these variables might often be preferable as taxonomic characters over call rate or note rate, which are heavily influenced by various factors. Dominant frequency is also comparatively static and only weakly affected by temperature, but depends strongly on body size. As with other taxonomic characters, strong call divergence is typically indicative of species-level differences, whereas call similarities of two populations are no evidence for them being conspecific. Taxonomic conclusions can especially be drawn when the general advertisement call structure of two candidate species is radically different and qualitative call differences are thus observed. On the other hand, quantitative differences in call traits might substantially vary within and among conspecific populations, and require careful evaluation and analysis. We provide guidelines for the taxonomic interpretation of advertisement call differences in sympatric and allopatric situations, and emphasize the need for an integrative use of multiple datasets (bio-acoustics, morphology, genetics), particularly for allopatric scenarios. We show that small-sized frogs often emit calls with frequency components in the ultrasound spectrum, although it is unlikely that these high frequencies are of biological relevance for the majority of them, and we illustrate that detection of upper harmonics depends also on recording distance because higher frequencies are attenuated more strongly. Bioacoustics remains a prime approach in integrative taxonomy of anurans if uncertainty due to possible intraspecific variation and technical artifacts is adequately considered and acknowledged.

“…Male acoustic signaling is a common reproductive behavior observed in animals worldwide (Bradbury & Vehrencamp, 2011; Wilkins et al, 2013). Vocal communication strategies change adaptively in response to a variety of abiotic and biotic noises (Lengagne & Slater, 2002; Shen et al, 2015; Shen & Xu, 2016) to maximize individual fitness through sexual selection (Halfwerk et al, 2019). Vocal organ structure can differ even within a species, and allometric constraints between body size and call frequency have been widely reported in anuran species (Duellman & Trueb, 1994; Tonini et al, 2020; Ziegler et al, 2016).…”

Frogs are a representative taxon that use advertisement calls to aid in reproduction. In most frog species, calls vary with body size, and allometric constraints between body size and call frequency have been widely reported among anuran species. Although this variation is an important driver of sexual selection in frogs, male advertisement call strategies may also vary according to body size. In this study, we conducted playback experiments on the male forest green tree frog (Zhangixalus arboreus) to determine whether male advertisement call characteristics and strategies vary according to body size and the amplitude of intraspecific chorus noise. The results indicated that the calls of larger individuals are louder and lower than those of smaller ones, who call more frequently; moreover, the calls become lower, and the number of calls decreases, as noise levels increase. These findings suggest that forest green tree frog emits lower calls or refrains from calling when chorus noise increases, and that intraspecific variation in advertisement call characteristics can induce different strategies in response to chorus noise. Because advertisement call variation with body size is common among frog species, intraspecific variation in male advertisement call strategies may also be a common phenomenon.
