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

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 pRayleigh statistics for lunar and tidal amplitude synchrony in settlement and successful spawning of Stegastes partitus in the upper Florida Keys.
