Frequency jumps and subharmonic components in calls of female Odorrana tormota differentially affect the vocal behaviors of male frogs
<p><span>Many studies have demonstrated that sounds containing nonlinear phenomena (NLP) can influence the behavior of receivers. However, the specific functions of different NLP components have received less attention. In most frog species, females produce few or no vocalizations; in contrast, female <em>O</em></span><span><em>dorrana</em> <em>tormota</em></span><span> exhibit a diverse range of calls that are rich in NLP components. Previous field playbacks have shown that female calls can elicit responses from male frogs. Therefore, we conducted a phonotaxis experiment to investigate the differential effects of different NLP calls by female <em>O. tormota</em> on the vocal behavior of male frogs. The results of our study revealed that calls with subharmonics elicited a greater number of short calls and answering calls from male frogs than calls with frequency jumps. Conversely, calls with frequency jumps triggered more staccato calls from males than calls with subharmonics. Additionally, during the phonotaxis experiments, we recorded the initial vocalizations of males in response to playbacks of female calls. The majority of males first produced short calls. Under calls with frequency jumps, most of the male frogs approaching within 10 cm of the loudspeaker produced staccato calls instead of "meow" calls or short calls. While under calls with subharmonics, most male frogs preferred to produce short calls. Our findings demonstrate that frequency jumps and subharmonic components in the calls of female <em>O. tormota</em> have different effects on male vocal behaviors.</span></p>

Allometric escape from acoustic constraints in frog calls is rare
<p class="AbstractSummary">Allometric constraint is a product of natural selection, particularly with respect to body size and traits constrained by physical properties thereof, such as metabolism, longevity, and vocal frequency. Parameters describing allometric relationships are conserved across most lineages, indicating that physical constraints dictate scaling patterns in deep time, despite substantial genetic and ecological divergence among organisms. Acoustic allometry (sound frequency ~ body size) is conserved across frogs, in defiance of massive variation in both body size and frequency. Here, we find four major instances of allometric escape, potentially deriving from ecomorphological adaptations to new signal modalities and invasion of biogeographic regions. In these instances of allometric escape, the optima and strength of the scaling relationship are different than expected for most other frog species, representing new adaptive regimes of body size ~ call frequency. Allometric constraints in frogs are highly conserved and have rarely promoted allometric escape despite frequent invasions of new adaptive regimes and dramatic ecomorphological divergence. Our results highlight instances in which natural and sexual selection combined could overcome physical constraints on sound production.</p>

Female choice scores and Peak Frequency and Duration in calls from Wood frog chorus recordings
<p>A limitation in bioacoustic studies has been the inability to differentiate individual sonic contributions from group-level dynamics. We present a novel application of acoustic-camera technology to investigate how individual wood frogs calls influence chorus properties, and how variation influences mating opportunities. We recorded mating calls and used playback trials to gauge preference for different chorus types in the laboratory. Males and females preferred chorus playbacks with low variance in dominant frequency. Females preferred choruses with low mean peak frequency. Field studies revealed more egg masses laid in ponds where males chorused with low variance in dominant frequency. We also noted a trend towards more egg masses laid in ponds where males called with low mean frequency. Nearest neighbor distances influenced call timing (neighbors called in succession) and distances increased with variance in chorus frequency. Results highlight the potential fitness implications of individual-level contributions to a bioacoustic signal produced by groups.</p>
