“…BBCs with peak frequencies up to 150 kHz are the main calls of Antillean manatee (Trichechus manatus manatus), which not only play an important role in orientation, but are also vital for social and mother-infant communication (Ramos et al 2020). In other species, the increase of ultrasonic components has been linked to elevated negative emotions of the neonates (Ise & Ohta 2009;Zaytseva et al 2017) and elicits immediate maternal care (Jourjine et al 2023), strengthening mother-infant ties (Guoynes & Marler 2021). Thus, broadband calls (particularly call rate and ultrasound frequency distribution) of giant panda neonates may also be related to arousal levels (rat, Rattus norvegicus: Ise & Ohta 2009; fat-tailed gerbils, Pachyuromys duprasi: Zaytseva et al 2017), where we evidence in the playback experiments that the ultrasonic components of these calls can stimulate maternal motivation and provide the neonates with immediate maternal care.…”

“…Usually, broadband calls are correlated with arousal levels (Keesom et al 2015;Walter & Schnitzler 2019) and convey more urgent information to conspecifics. Broadband calls have the advantages of high range resolution and orientation (Jones et al 2008) and are used in mother-infant communications to allow the mother to provide timely maternal care (Ramos et al 2020;Jourjine et al 2023). Previous studies have shown that broadband calls can influence nursing and other maternal behaviors (White et al 1992;Ihnat et al 1995) indicating their importance for offspring survival.…”

Giant panda (Ailuropoda melanoleuca) neonates use broadband calls to communicate with their mothers

Infant call structure should have evolved to elicit maximum maternal attention and investment. Neonates of giant pandas produce three types of vocalizations reported to be vitally important in the context of mother–infant communications. However, how cubs, 0–15 days old, communicate with their mothers to elicit maternal care remains unknown. We analyzed 12 different call parameters of 3475 squawks, 1355 squalls, and 491 croaks from 11 captive giant panda (Ailuropoda melanoleuca) neonates from age 0 to 15 days. In playback experiments, we also tested whether mothers could detect ultrasound. Our results show that neonates use broadband calls with ultrasonic frequencies up to 65 kHz to convey information about their physiological needs and to attract maternal care. In playback experiments, we tested if mothers reacted differently to broadband calls (BBC) than to artificially altered calls that included only frequencies <20 kHz (AUDC) or calls that included only frequencies >20 kHz (USC). Playback confirmed that, although adult females responded significantly less often to USC, BBC than to or AUDC, they could detect USC, BBC and generally made appropriate behavioral responses, indicating a potential benefit for neonates to utilize ultrasonic and broadband frequencies. Our findings provide a new insight into mother–infant communication in giant pandas and will be helpful for reducing the mortality of cubs, younger than 1 month old, in captivity.

“…For example, two sister species, P. maniculatus and P. polionotus , diverged from each other around 1.8 million years ago (Schenk, Rowe, and Steppan 2013) (Fig. 1A) but nonetheless vary in a number of innate behaviors (e.g., burrowing (Dawson, Lake, and Schumpert 1988), infant vocalization (Jourjine et al 2023), and thermoregulatory nesting (Lewarch and Hoekstra 2018)). In particular, these two species lie on opposite ends of the monogamy-promiscuity spectrum and, among other reproductive behaviors, exhibit differences in the degree of sexual dimorphism in parental care (Bendesky et al 2017; Foltz 1981).…”

The evolution of innate behaviors is ultimately due to genetic variation likely acting in the nervous system. Gene regulation may be particularly important because it can evolve in a modular brain-region specific fashion through the concerted action ofcis- andtrans-regulatory changes. Here, to investigate transcriptional variation and its regulatory basis across the brain, we perform RNA sequencing (RNA-Seq) on ten brain subregions in two sister species of deer mice (Peromyscus maniculatusandP. polionotus) – which differ in a range of innate behaviors, including their social system – and their F1hybrids. We find that most of the variation in gene expression distinguishes subregions, followed by species. Interspecific differential expression (DE) is pervasive (52–59% of expressed genes), whereas the number of DE genes between sexes is modest overall (∼3%). Interestingly, the identity of DE genes varies considerably across brain regions. Much of this modularity is due tocis-regulatory divergence, and while 43% of genes were consistently assigned to the same gene regulatory class across subregions (e.g., conserved,cis-, ortrans-regulatory divergence), a similar number were assigned to two or more different gene regulatory classes. Together, these results highlight the modularity of gene expression differences and divergence in the brain, which may be key to explain how the evolution of brain gene expression can contribute to the astonishing diversity of animal behaviors.
