Singing Fish, Circadian Rhythms, and Melatonin/ Curr. Biol., Sep. 22, 2016 (Vol. 26, Issue 19)

“Singing” Fish Rely on Circadian Rhythm and Melatonin for the Timing of Nocturnal Courtship Vocalization/ Curr. Biol., Sep. 22, 2016 (Vol. 26, Issue 19) - The patterning of social acoustic signaling at multiple timescales, from day-night rhythms to acoustic temporal properties, enhances sender-receiver coupling and reproductive success [ 1–8 ]. In diurnal birds, the nocturnal production of melatonin, considered the major vertebrate timekeeping hormone [ 9, 10 ], suppresses vocal activity but inc
