Fig. 8. (A) Representative example of a single grunt recorded at 16°C from a
nesting type I male midshipman fish. Bar, 10 ms. (B) Comparison of the power
spectrum of the representative grunt shown in A (grey trace) and the frequency
sensitivity of auditory saccular afferent neurons recorded from juvenile
(small and large) and adult (non-reproductive and reproductive) midshipman
fish. (C) Representative example of a growl recorded at 16°C from a
nesting type I male midshipman fish. Bar, 500 ms. (D) Comparison of the power
spectrum of the representative growl in C (grey trace) and the frequency
sensitivity of auditory saccular afferent neurons recorded from juvenile
(small and large) and adult (non-reproductive and reproductive) midshipman
fish. (E) Representative example of a hum recorded at 16°C from a nesting
type I male midshipman fish. Bar, 10 ms. (F) Comparison of the power spectrum
of the representative hum in E (grey trace) and the frequency sensitivity of
auditory saccular afferent neurons recorded from juvenile (small and large)
and adult (non-reproductive and reproductive) midshipman fish. Iso-intensity
response curves are based on vector strength (VS) of synchronization to
iso-intensity tones of 130 dB (re 1 µPa) and show median VS values for
juvenile and adult midshipman (filled circles, squares and triangles from
Fig. 4; open triangle,
non-reproductive female midshipman fish from
Sisneros and Bass, 2003).
