“…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).…”

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.

“…Among them, some species as Ameerega flavopicta, endemic to the Cerrado biome, were observed only in areas of Cerrado stricto sensu. A. flavopicta occupy open physiognomies of the Cerrado ecosystem, with males calling mainly from rock crevices (Toledo et al 2004;Costa et al 2006;Magrini et al 2010;Martins and Giaretta 2012). The species is considered to be of ''Least Concern'' by the International Union for Conservation of Nature (IUCN, 2013).…”

Even harboring a high diversity and many endemic species of amphibians and reptiles, the Cerrado biome has shown drastic changes due to the conversion of natural areas into pastures and plantations. Here, we present a checklist of amphibians and reptiles from southeastern state of Goiás, Central Brazil. This checklist was the result of collecting efforts of an inventory along the basin of the Piracanjuba and Peixe rivers carried out between September 2010 and January 2011. We recorded 39 amphibians and 40 reptiles. These results were also compared to other studies in the Cerrado biome. Our results showed that this region has a rich herpetofauna, despite the progress of anthropogenic activities in the region.

“…Call duration and interval between calls were larger than those from other states (Toledo et al, 2004;Costa et al, 2006) and even from other populations in Minas Gerais (Haddad and Martins, 1994). However, Magrini et al (2010) reported variation in call parameters of A. flavopicta (call duration, intercall interval, call rate, and frequency) among localities, a population from Perdizes municipality (Minas Gerais) being similar to the population we studied at Pirapitinga in all these parameters. We observed a fundamental frequency (1.9 6 0.05 Khz) in the calls of the studied population of A. flavopicta that is not reported in any other study of the species' call (see Haddad and Martins, 1994;Toledo et al, 2004;Costa et al, 2006;Magrini et al, 2010).…”

Dominant frequency at the Pirapitinga population was similar to the value reported for populations at localities in central and southeastern Brazil (Toledo et al, 2004) and higher than those reported for Parque Estadual da Serra de Caldas Novas (Costa et al, 2006) and Santana do Riacho (Haddad and Martins, 1994).…”
