From: Split spawning realigns coral reproduction with optimal environmental windows
Coral spawning records for Scott Reef from 2007 to 2016. Spawning was either observed in situ or inferred from egg presence/absence and egg pigmentation around predicted spawning dates. When the full moon occurred in the middle (8th–22nd) of the usual March or October spawning month, then single-mass spawning occurred. However, when the full moon occurred early, in the first week of the usual spawning month, or the last week of the previous month, then split spawning occurred. The only exception to this rule was the mass spawning event after an early full moon on the 4th October in 2009. Full moon dates are given in the moon icons above the bars. Pink bars indicate mass spawning and blue bars indicate split spawning. The white bars in 2016 indicate no spawning due to a severe coral bleaching event. More detail on these spawning records are presented in Supplementary Table 2
