Abstract

The role of hybridization through multispecific synchronous spawning in the evolution of reefbuilding corals has been discussed since the 1990s particularly for the genus Acropora However F1 hybrids have been reported as common in only one case in the Caribbean with no evidence of mechanisms that would allow continuous reproduction of the hybrids In this study we report for the first time the fecundity of two F1 hybrid colonies produced experimentally from two IndoPacific species A intermedia and A florida These F1 hybrids spawned at the same time as the parental corals Backcrossing and F1 hybrid crossing were successful in both directions Furthermore more than 90 selffertilization was achieved in an F1 hybrid although it was negligible in the parental corals While it is possible that the F1 hybrid was a chimera these results suggest that some products of interspecific hybridization may persist as the offspring of selffertilizing F1 hybridsWe are grateful to three anonymous reviewers for their help and constructive comments We thank M Omori and S Hosaka for enthusiastic support to the present study S Takahashi Y Oku H Shirahata A Toho and S Kitanobo for assistance with crossing experiments and N Knowlton for reviewing the manuscript and giving useful comments This study was supported by JSPS KAKENHI 26440225 to NI
