“…We found that female and male T. scripta elegans have a similar range of sensitivities (0.2–0.9 kHz), whereas the ABR threshold of females was significantly lower than that in males. These results provide convincing evidence that sexually dimorphic hearing sensitivity has emerged in turtles, and that the hearing of females is more sensitive than that of males, which is consistent with previous findings for frogs and toads (Wang et al 2016, 2019; Yang et al 2018).…”

“…At present, sexual selection (Lovich and Gibbons 1992; Willemsen and Hailey 2003), fecundity effort (Kupfer 2009; Olsson et al 2010), and niche divergence (Thom et al 2010) are the three major hypotheses that have been proposed to explain the evolution and maintenance of sexual size dimorphism (SSD). Although most studies on sexual dimorphism have concentrated on body size or shape, sexually dimorphic hearing sensitivity has also been reported in some species of amphibians (Narins and Capranica 1976; Wang et al 2016, 2019; Yang et al 2018). Remarkably, such sexually dimorphic hearing sensitivity may primarily result from sexual dimorphism of the auditory organs (particularly tympanic membranes) and their physical properties (Dijk et al 2002; Feng et al 2006; Shen et al 2011; Liu et al 2014; Wang et al 2016).…”

Hearing sensitivity is of general interest from the perspective of understanding the functionality and evolution of vertebrate auditory systems. Sexual dimorphism of auditory systems has been reported in several species of vertebrates, but little is known about this phenomenon in turtles. Some morphological characteristics, such as middle ear and tympanic membrane that influence the hearing sensitivity of animals can result in hearing sexual dimorphism. To examine whether sexual dimorphism in hearing sensitivity occurs in turtles and to compare hearing characteristics with respect to the shape of the tympanic membrane, we measured the hearing sensitivity and tympanum diameter in both sexes of Trachemys scripta elegans. The results showed that, with the exception of 0.9 kHz, auditory brainstem response thresholds were significantly lower in females than in males for frequencies in the 0.2–1.1 kHz range, indicating that the hearing of females shows greater sensitivity. No significant differences were detected in the tympanum diameter of both sexes. These results showed that sexually dimorphic hearing sensitivity has evolved in turtles; however, this difference does not appear to be related to differences in the size of the tympanic membrane. The possible origin and function of the sexual differences in auditory characteristic are discussed.

Daryono BS, Mushlih M, Perdamaian ABI. 2021. Crowing sound and inbreeding coefficient analysis of Pelung chicken (Gallus gallus domesticus). Biodiversitas 22: 2451-2457. Pelung is one of the crowing-typed chickens from Indonesia. The bioacoustics characters of Indonesian crowing-typed chicken especially Pelung chicken were less documented. This study aimed to characterize crowing sound and to study the inbreeding coefficient of the Pelung chicken. In this study, crowing voice of 77 male Pelung chicken was recorded. Bioacoustics analyses of crowing voice were done using Adobe Audition CS5.5 and PRAAT 5.3.66 software. The results showed that chicken crowing consisted of front sound (first syllable), middle sound (second syllable) and end sound (third syllable). Each section of Pelung crowing had specific characteristics compared to other chicken breeds and varied among champions and nonchampions. Champion chicken had slowed and clear first and second syllable, sound energy was lower in first syllable then decrease at second syllable and has bitu gantung third syllable. Crowing duration and fundamental frequency (F0) of champion and non-champion were not statically different. The inbreeding coefficient reached 0.53 in several Pelung champions. Based on the research findings, bioacoustics software was applicable to assist the chicken show.

“…Auditory brainstem response (ABR) measurement is a noninvasive and rapid method to measure hearing sensitivity; its use has been validated for frogs [26, 27], toads [28], and reptiles [18, 29]. Our aim was to demonstrate that aging is accompanied by changes in turtle hearing sensitivity by measuring ABR, to assess ontogenetic changes in post-hatchling-to-reproductive T. scripta elegans adults.…”
