“…Changes in the acoustic behavior of males are adaptations of species that vocalize in aggregates; males that avoid acoustic overlap are more likely to attract females (sullivan & leeK 1987(sullivan & leeK , RiCHaRdson et al 2008. The intensity of the call regulates the spacing between males in the chorus and contributes to determining the aggressive threshold of males (BRenoWitz 1989, liGnau & Bastos 2007. When males in a chorus change their acoustic behavior and avoid overlap, for instance by decreasing the amplitude of their calls, they also modify the acoustic threshold that elicits aggressive interactions and minimize costs from aggressive calls and physical combat (BRenoWitz & Rose 1994.…”

“…Environmental factors (air temperature and humidity) are known to influence the temporal parameters of calls , liGnau & Bastos 2007, silva et al 2008. As a consequence ectothermy,'the metabolic efficiency of amphibians improve with increasing temperature (Wells 2007) et al (2010), this relationship may represent a mechanism to avoid greater energy expenditure at higher temperatures.…”

“…Um estudo mais detalhado comparando o canto de anúncio das três espécies precisa ser realizado, mas com base nessa comparação simples, acreditamos que os cantos das três espécies sejam distintos o suficiente e corroboram o status de espécies distintas que atribuímos a essas amostras. Somada a estas observações, pelo menos em Hylodes heyeri Haddad, Pombal, & Bastos, 1996, a única espécie onde a relação entre variáveis do canto e a temperatura foi estudada, o número de notas não esta correlacionado com variações da temperatura (LINGNAU & BASTOS 2007).…”

Descrevemos uma nova espécie de Hylodes da Serra Negra, Município de Santa Bárbara do Monte Verde, Minas Gerais, sudeste do Brasil. A nova espécie pertence ao grupo Hylodes lateristrigatus, apresentando as seguintes características distintivas: corpo pequeno, focinho truncado em vistas dorsal e lateral, escudos da superfície dorsal dos discos dos dedos pouco desenvolvidos, superfície dorsal do corpo e coxas marrom-oliváceo com manchas escuras no dorso e listras nas patas traseiras. A nova espécie se distingue das demais do grupo pelo número de notas e características físicas do canto de anúncio e por vocalizar tanto de dia quanto à noite. Este é o primeiro registro de vocalização noturna para o gênero. Apresentamos descrições da vocalização e informações sobre a história natural da nova espécie. Discutimos a distribuição das espécies do gênero Hylodes, em relação às principais serras do leste do Brasil e seus sistemas de drenagem atuais.

“…Body size is usually strongly correlated with spectral traits, and this correlation also holds between species, suggesting that fundamental and dominant frequencies are under morphological constraints, with smaller frogs (with shorter vocal cords) producing calls at higher frequencies (Gerhardt & Huber 2002;Gingras et al 2013). This correlation is almost universal in anurans, with few exceptions (Sullivan 1984;Sullivan & Malmos 1994;Lingnau & Bastos 2007), including frogs that can actively adjust frequency depending on the context (see above). Whereas body size effects on frequency might characterize the vast majority of frog species, temporal traits have only rarely been suggested to be influenced by body size For between-individual variation of spectral traits it is appealing to hypothesize 'honest signalling', in which signals transfer reliable information on male quality from sender to receiver.…”

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.
