“…The pipoidae (ancestral to modern pipids including Xenopus ) emerged during the Jurassic ~170 mya and the genus Xenopus ~50 mya (Feng et al, 2017 ). The Rodentia diverged from a common ancestor with the Lagomorpa ~65 mya (Romanenko et al, 2012 ) and Scotinomys perhaps 7 mya (Fernández-Vargas et al, 2021 ). While characters related to reproductive signaling (such as sexual dimorphism) can be lost as well as gained evolutionarily (e.g., Leininger and Kelley, 2013 ), similarities in the distribution of androgen receptors in two evolutionarily very distant species ( Xenopus and Scotinomys , see below) suggest an ancient role in the coordination of vocal signaling during reproduction.…”

Vocal communication is used across extant vertebrates, is evolutionarily ancient, and been maintained, in many lineages. Here I review the neural circuit architectures that support intraspecific acoustic signaling in representative anuran, mammalian and avian species as well as two invertebrates, fruit flies and Hawaiian crickets. I focus on hindbrain motor control motifs and their ties to respiratory circuits, expression of receptors for gonadal steroids in motor, sensory, and limbic neurons as well as divergent modalities that evoke vocal responses. Hindbrain and limbic participants in acoustic communication are highly conserved, while forebrain participants have diverged between anurans and mammals, as well as songbirds and rodents. I discuss the roles of natural and sexual selection in driving speciation, as well as exaptation of circuit elements with ancestral roles in respiration, for producing sounds and driving rhythmic vocal features. Recent technical advances in whole brain fMRI across species will enable real time imaging of acoustic signaling partners, tying auditory perception to vocal production.

“…(ventral pouch) enables extension of the spectral range of vocal signals. Together with how the instrument is played, that is, the neural control which coordinates movements of the vocal organ (e.g., Fernandez-Vargas et al 2022;Nieder & Mooney, 2020), the constancy of ventral pouch lumen provides a compelling example for size-independency of the spectral range.…”

“…For example, pup isolation vocalizations used to induce maternal care are ubiquitous among rodents (Lingle et al., 2012). In addition, many rodents produce vocalizations as adults to mediate a variety of social interactions, including mate acquisition (Fernandez‐Vargas et al., 2022). Surprisingly, although spectral features of vocal repertoires differ at various life stages (e.g., Grimsley et al., 2013; Riede et al., 2015; Yurlova et al., 2020; Zaytseva et al., 2019), the F0 ranges of certain high‐frequency vocalizations (aka ‘ultrasonic vocalizations’, USVs) overlap between small pups and large adults (e.g., Grimsley et al., 2011; Liu et al., 2003; Yurlova et al., 2020).…”

Postnatal remodeling of the laryngeal airway removes body size dependency of spectral features for ultrasonic whistling in laboratory mice

In many mammals, spectral properties of acoustic signals scale with body size within and among species. In rodents, however, despite drastic changes in body size, fundamental frequency (F0) range of ultrasonic whistles produced for social communication remain relatively uniform from birth to adulthood. Such divergent patterns may be due to a novel sound production mechanism unique to rodents involving an intralaryngeal midline pocket termed the ventral pouch. In this study, we analyzed the postnatal shape and size of the laryngeal airway in CD1 mice over ontogeny to better understand the association between ventral pouch geometry and F0 of ultrasonic whistles. Ventral pouch volume (0.06 ± 0.01 mm3) did not differ between pups and 1‐year‐old adults despite extensive shape‐inducing remodeling of the intralaryngeal musculature and connective tissue. In contrast, ventral pouch volume was 50% less in 2‐year‐old compared to 1‐year‐old mice. Thus, allometry of the laryngeal airway appears to explain spectral overlap between ultrasonic whistles of young, small mice and older, larger mice. The causal association between the reduction in vocal behavior and a seemingly shrinking ventral pouch in geriatric mice remains unclear. Together, these data inform our understanding of the postnatal development and remodeling of the intralaryngeal airway in Mus musculus.

“…One such group is the rodents. Although less well known for their vocal behaviors compared to other taxa, many rodent species are highly vocal, and they use vocalization in many of the same social contexts as other mammals (Banerjee et al, 2019;Fernández-Vargas et al, 2021;Okanoya and Screven, 2018;Pasch et al, 2013;Rieger and Marler, 2018). Studies in laboratory mice (e.g., Mus musculus strain C57Bl6/j) have focused on ultrasonic vocalizations ("USVs") made by neonates ("pups") when isolated from their parents (e.g., Zimmer et al, 2019).…”
