“…This is consistent with the proposed behavioral role of seasonal plasticity in peripheral auditory function enabling detection of higher harmonics (see Fig.1A,B) in shallow water (Bass and Clark, 2003) (also see Fine and Lenhardt, 1983;Sisneros and Bass, 2003). Similar to hair cell recordings (Fig.2A,C), auditory afferents in non-reproductive females had weak responses at 130dBre1Pa at frequencies above 140Hz with the greatest enhancement among reproductive females at frequencies >140Hz and up to ~340Hz (Sisneros and Bass, 2003).…”

SUMMARYVertebrates displaying seasonal shifts in reproductive behavior provide the opportunity to investigate bidirectional plasticity in sensory function. The midshipman teleost fish exhibits steroid-dependent plasticity in frequency encoding by eighth nerve auditory afferents. In this study, evoked potentials were recorded in vivo from the saccule, the main auditory division of the inner ear of most teleosts, to test the hypothesis that males and females exhibit seasonal changes in hair cell physiology in relation to seasonal changes in plasma levels of steroids. Thresholds across the predominant frequency range of natural vocalizations were significantly less in both sexes in reproductive compared with non-reproductive conditions, with differences greatest at frequencies corresponding to call upper harmonics. A subset of non-reproductive males exhibiting an intermediate saccular phenotype had elevated testosterone levels, supporting the hypothesis that rising steroid levels induce non-reproductive to reproductive transitions in saccular physiology. We propose that elevated levels of steroids act via long-term (days to weeks) signaling pathways to upregulate ion channel expression generating higher resonant frequencies characteristic of nonmammalian auditory hair cells, thereby lowering acoustic thresholds.

“…This enhanced saccular sensitivity may be adaptive and function to increase the probability of signal detection by sneaker males in shallow water environments where the propagation of acoustic signals is greatly affected by substrate composition and water depth (Rogers and Cox 1988;Bass and Clark 2003;Maruska and Sisneros 2015). The relative high frequencies (approximately those greater than 180 Hz) contained with type I vocalizations will propagate further than the calls' fundamental frequencies in shallow water due to the inverse relationship between water depth and the cutoff frequency of sound transmission (Fine and Lenhardt 1983;Rogers and Cox 1988;Bass and Clark 2003). In addition, the substrate composition (e.g., the rocky substrate of the intertidal zone where midshipman breed) can greatly influence the speed of sound in the bottom substrate and affect the cutoff frequency of signal propagation which can attenuate the transmission of low-frequency acoustic signals (e.g., the fundamental frequencies of type I male vocalizations) (Rogers and Cox 1988).…”

“…In shallow (10-100 m) and very shallow (<5 m) water systems (see Bass and Clark, 2003), lower frequency components of an acoustic signal have a higher level of attenuation, while the higher frequency components propagate many times farther (Bass and Clark, 2003;Fine and Lenhardt, 1983;Mann and Lobel, 1997). Fine and Lenhardt demonstrated that the frequencies around the fundamental frequency of the boatwhistle of O. tau (around 200 Hz) had an attenuation of -29.5 dB over 7 m, while upper harmonics around 800 Hz only had an attenuation of -13 dB over the same distance (Fine and Lenhardt, 1983). Thus, for B. trispinosus, the high-frequency harmonic components of many of the hoots, grunts and particularly the grunts with beats may be an adaptation to increase the propagation distance of the call in shallow water habitats.…”

SUMMARYToadfishes (Teleostei: Batrachoididae) are one of the best-studied groups for understanding vocal communication in fishes. However, sounds have only been recorded from a low proportion of taxa within the family. Here, we used quantitative bioacoustic, morphological and phylogenetic methods to characterize vocal behavior and mechanisms in the three-spined toadfish, Batrachomoeus trispinosus. B. trispinosus produced two types of sound: long-duration 'hoots' and short-duration 'grunts' that were multiharmonic, amplitude and frequency modulated, with a dominant frequency below 1 kHz. Grunts and hoots formed four major classes of calls. Hoots were typically produced in succession as trains, while grunts occurred either singly or as grunt trains. Aside from hoot trains, grunts and grunt trains, a fourth class of calls consisted of single grunts with acoustic beats, apparently not previously reported for individuals from any teleost taxon. Beats typically had a predominant frequency around 2 kHz with a beat frequency around 300 Hz. Vocalizations also exhibited diel and lunar periodicities. Spectrographic crosscorrelation and principal coordinates analysis of hoots from five other toadfish species revealed that B. trispinosus hoots were distinct. Unlike any other reported fish, B. trispinosus had a bilaterally divided swimbladder, forming two separate swimbladders. Phylogenetic analysis suggested B. trispinosus was a relatively basal batrachoidid, and the swimbladder and acoustic beats were independently derived. The swimbladder in B. trispinosus demonstrates that toadfishes have undergone a diversification of peripheral sonic mechanisms, which may be responsible for the concomitant innovations in vocal communication, namely the individual production of acoustic beats as reported in some tetrapods.
