Feeding 11-ketotestosterone coated scallops to toadfish increases their calling behavior, [7] which identifies 11-ketotestosterone, an androgen hormone, as a mediator of midshipman fish vocalization. There are also high levels of aromatase, an estrogen-generating enzyme, in the hindbrain vocal motor region. Estradiol steroids and their ...
Sonograms of female copulatory vocalizations of a human female (top), female baboon (middle), and female gibbon (bottom), [19] with time being plotted on the x-axis and the pitch being represented on the y-axis. In non-human primates, copulatory vocalizations begin towards the end of the copulatory act or even after copulation. [2]
Toothed whale (odontocete) vocal anatomy. Most mammalian species produce sound by passing air from the lungs across the larynx, vibrating the vocal folds. [3] Sound then enters the supralaryngeal vocal tract, which can be adjusted to produce various changes in sound output, providing refinement of vocalizations. [3]
Later, he put a male cricket behind a microphone and female crickets in front of a loudspeaker. The females were not moving towards the male but towards the loudspeaker.
