From: Circatrigintan instead of lunar periodicity of larval release in a brooding coral species

Auto-correlation analyses of planulae released from the eight S. pistillata colonies (a–h). Time lag was set at a maximum of 45 days. Each point in the graph represents the correlation coefficient of the data at time t + n compared to the data at time t, where n is the time lag in days. Coral colonies #1, 2, 5, 7 and 8 show a clear wave pattern, indicative of recurrence in released planulae behaviours. Trend lines were composed of damped sine waves and used to approximate period.
