“…Moreover, we did not detect within-individual variation in the dominant frequency analysed for both the advertisement and aggressive calls throughout the night. The lack of variation in the dominant frequency can be explained because this parameter is usually correlated with morphological traits, mainly male size, which is stable over time (Morais et al 2012;Bee et al 2013).…”

“…Besides the within-individual variation and social context, anuran acoustic parameters can also be influenced by environmental variables and/or be limited by male morphological traits (e.g. Lemes et al 2012;Morais et al 2012;Bee et al 2013). The dominant frequency of the calls is usually correlated with male size, while temporal parameters are more influenced by air temperature (e.g.…”

Male size can also influence calling site use, with larger males defending better calling sites, which may increase reproductive success (e.g.…”

In anurans, vocalization is the primary communication form and acoustic parameters are influenced by climatic conditions, but also by social contexts. We investigated calling site use and within-individual variation of acoustic parameters throughout the night in the gladiator-frog Hypsiboas goianus. We expected that large males would call closer to the water and at higher perches to avoid dehydration and maximize sound propagation. Furthermore, we tested the prediction that males would emit more aggressive calls early in the night and more advertisement calls late at night. Male size was not correlated with either distance from the water or perch height. However, as expected, males of H. goianus adopted a calling strategy that consisted of emitting more aggressive calls early in the night and more advertisement calls later in the night. Furthermore, repetition rate and interval between notes of the aggressive calls and repetition rate of the advertisement calls showed within-individual variation throughout the night that agreed with our expectations. The calling strategy of H. goianus is probably related to the establishment of calling sites early in the night and an investment in female attraction in the middle of the night when males' aggressive interactions have faded away, or due to habituation increasing the males' aggressive thresholds. This is the first study investigating within-individual patterns of acoustic parameters of calls throughout the night for anurans.

Peer Review #2 of "A unique mating strategy without physical contact during fertilization in Bombay Night Frogs (Nyctibatrachus humayuni) with the description of a new form of amplexus and female call (v0.1)"

Anurans show the highest diversity in reproductive modes of all vertebrate taxa, with a variety of associated breeding behaviours. One striking feature of anuran reproduction is amplexus. During this process, in which the male clasps the female, both individuals' cloacae are juxtaposed to ensure successful external fertilization. Several types of amplexus have evolved with the diversification of anurans, and secondary loss of amplexus has been reported in a few distantly related taxa. Within Nyctibatrachus, a genus endemic to the Western Ghats of India, normal axillary amplexus, a complete loss of amplexus, and intermediate forms of amplexus have all been suggested to occur, but many species remain unstudied. Here, we describe the reproductive behaviour of N. humayuni, including a new type of amplexus. The dorsal straddle, here defined as a loose form of contact in which the male sits on the dorsum of the female prior to oviposition but without clasping her, is previously unreported for anurans. When compared to known amplexus types, it most closely resembles the form of amplexus observed in Mantellinae. Furthermore, we prove that, opposed to the situation in most anurans, male semen release happens before egg deposition. We hypothesize that the male ejaculates on the female's dorsum and that sperm subsequently runs from her back and hind legs before fertilizing the eggs. A second feature characterizing anuran breeding is the advertisement call, mostly produced solely by males. Despite recent descriptions of several new Nyctibatrachus species, few studies have explored their vocal repertoire. We describe both the male advertisement call and a female call for N. humayuni. The presence of a female call has not been reported within Nyctibatrachidae, and has been reported in less than 0.5% of anuran species. Altogether, our results highlight a striking diversity and several unique aspects of Nyctibatrachus breeding behaviour.

“…Call variation within and between individuals of many anurans is influenced by individual motivation of the vocalizing male owing to numerous internal and/or external factors (Wells, 2007;Köhler et al, 2017). For example, social context could change the frequency of calls (Bee, Perrill & Owen, 2000;Reichert & Gerhardt, 2013) and temperature effects are linked to pulse rate and call duration (CD) (Lingnau & Bastos, 2007;Pröhl et al, 2007;Gasser, Amézquita & Hödl, 2009;Bee, Suyesh & Biju, 2013;Ziegler, Arim & Bozinovic, 2015) at the individual level. Furthermore, body size could constrain the frequency of calls (Gerhardt & Huber, 2002;Gingras et al, 2013) and physical or physiological damages could generate differences in calls (Hoffmann & Kloas, 2012;Pröhl et al, 2013) among individuals.…”

Background Species-specific advertisement calls are the main mechanism of transmitting information between individuals in anuran amphibians and are therefore indispensable for anuran survival and reproduction. Survey methods that monitor these calls can be used for rapid species recognition, behavioral experiments, and conservation monitoring. In this study, we described in detail 10 call parameters from three sympatric species in the genus Microhyla and analyzed the differences in call parameter among these species to provide a basis for systematic monitoring, acoustic analysis and taxonomic study of this genus. Methods The quantitative analyses of temporal and spectral call parameters were used in our study for the advertisement calls of three sympatric Microhyla species (M. beilunensis, M. fissipes and M. heymonsi) in Zhejiang Province, East China. Results Our results showed the following: (1) Significant differences existed among the three sympatric Microhyla species in call duration (CD), call interval (CI), number of pulses (NP), pulse rate, call intensity (CIT), dominant frequency (DF) and frequency of the first to fourth formants (F1, F2, F3 and F4). (2) Some spectral parameters (DF, F1 and F3) were negatively correlated with the body size of the vocalizing individuals in each species. (3) The coefficients of variation within individuals (CVw) for CIT, DF and F1–F4 were smaller than 5%, whereas the CVW for CI was larger than 10% in each species. (4) The principal component analysis and discriminant function analysis showed that call parameters could distinguish the three Microhyla species. (5) The phylogenetic generalized least squares analysis showed that phylogenetic relationships affected CD and NP against snout-vent length (SVL), DF and NP against CD, and NP against DF, but not of DF against SVL; based on the phylogenetic analysis, CD and NP were not related to SVL, but DF was negatively related to SVL.
