Rayleigh statistics for lunar and tidal amplitude synchrony in settlement and successful spawning of <i>Stegastes partitus</i> in the upper Florida Keys.

<p>Recruits were obtained from monthly surveys; settlement-stage larvae were obtained from light traps. Otolith microstructure of recruits was used to back-calculate settlement timing and recruit densities were adjusted for mortality to provide a more precise estimate of settlement magnitude. All tests were significant at p<0.001. Z is the Rayleigh test statistic; Day is the mean peak in lunar or maximum tidal amplitude calculated from mean vector angle; s is the mean angular deviation; Day 1 is the new moon.</p><p>Rayleigh statistics for lunar and tidal amplitude synchrony in settlement and successful spawning of <i>Stegastes partitus</i> in the upper Florida Keys.
