“…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).…”

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.

“…Some studies found evidence of clinal variation in calls, either resulting from altitudinal differences between populations (Narins & Smith 1986;Lüddecke & Sánchez 2002;O'Neill & Beard 2011;Narins & Meenderink 2014;Baraquet et al 2015), or from latitudinal and/or longitudinal differences (Smith et al 2003a;Bernal et al 2005;Pröhl et al 2007;Magrini et al 2010;Faria et al 2013;Baraquet et al 2015;Forti et al 2016).

“…Additionally, geographic barrier effects on populational differences in frog calls have been recorded (Simões et al 2008;Magrini et al 2010;. Pleiotropic effects of body size may also contribute to call trait differences between different populations: populations might differ in body size and, as a consequence, in acoustic traits (Nevo & Capranica 1985;Narins & Smith 1986;Castellano et al 2000;Smith et al 2003b;Márquez-García et al 2009;O'Neill & Beard 2011;Micancin & Wiley 2014;Narins & Meenderink 2014;Baraquet et al 2015). Although rarely tested, geographic variation in predation may also play an important role in the evolution and maintenance of mating signal divergence (Trillo et al 2012).…”

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.

“…arenarum presents a neotropical distribution (Frost, 2015), in a variety of habitats, including coastal environments, rural or urban areas ; while, the distribution of H. cordobae is restricted to highlands of Co´rdoba and San Luis provinces, Argentina. This restricted distribution, to the highlands of central Argentina and with a broad altitudinal range, together with the report by the IUCN (2014) as species with insufficient data, makes this species interesting for study (Baraquet et al, 2013(Baraquet et al, , 2015.…”

-The grazing of amphibian tadpoles has a significant effect on structure and function of freshwater algal communities. The aim of this study was to evaluate the composition of the diet, the amplitude and degree of overlap of the trophic niche of tadpoles of Rhinella arenarum and Hypsiboas cordobae. We captured tadpoles using nets in pond. Food items were identified to genus level and assigned to morphological guilds. The diet of both species consisted of microalgae, with a predominance of diatoms, but representatives of Cyanobacteria, Chlorophyta, Euglenozoa, Dinozoa and Ciliophora, were also recorded. A greater abundance was observed in H. cordobae diet, with diversity and richness showed significant differences between species. The proportion of individuals of each guild was different in the two species. As regards the size of the taxa consumed, both species consumed a higher proportion of small organisms. The differences in the diet of these species could be explained by different behaviors for food acquisition in the water column, as H. cordobae tends to be nektonic and R. arenarum benthic. The analysis of diets suggest that the quantity of food available to the tadpole anurans is very low; this could be due to water turbidity, depth, substrate type and strong variations in conductivity in a short period of time.
