Sex Steroid-Dependent Modulation of Acoustic Communication Systems in Fishes

摘要: Acoustic communication is widespread among fishes, the largest extant group of vertebrates, and in many vocal teleost species it essential for their reproductive social behaviors. Recent evidence suggests that a fish’s internal hormonal state can profoundly influence its ability to produce perceive acoustic signals. Here, we review current knowledge how sex steroids auditory capabilities motor production signals two incipient model teleosts, plainfin midshipman fish Porichthys notatus African cichlid Astatotilapia burtoni. Studies these systems show steroid-mediated improvements vocal-acoustic processing are typically associated with readiness. This especially holds true rely heavily on signaling during seasonal breeding such as fish, well non-seasonally like cichlids appear use sound one component more complex multimodal courtship repertoire. Evidence reproductive-state dependent plasticity supported by changes gonadal state, circulating sex-steroids (testosterone, 11-ketotestosterone, estradiol), steroid receptor expression peripheral central structures concurrent sensitivity production. form steroid-dependent proposed be an evolutionary labile solution enhancing detection The abundance diversity present unique future opportunities explore this may have shaped sexual selection evolution fishes.
