摘要

摘要为了证实之前的发现，加勒比Acropora珊瑚的杂交发生在最近的地质过去，我们确定了两个亚化石Acropora prolifera样本的铀钍(U-Th)年龄，这些样本来自佛罗里达州东南部海岸附近的近岸珊瑚死亡组合。我们的研究结果表明，A, prolifera在全新世晚期存在于佛罗里达东南部，这证实了加勒比海acroporid的杂交发生在20世纪70年代和80年代该地区范围内的灭绝之前。

U-Th dating of Holocene age Acropora prolifera (Lamarck, 1816) colonies confirms coral hybridization is not a recent phenomenon.

Abstract. To confirm previous findings that hybridization of Caribbean acroporid corals occurred in the recent geologic past, we determined the uranium-thorium (U-Th) ages of two subfossil Acropora prolifera samples collected from nearshore coral death assemblages located off the coast of southeastern Florida. Our results indicate that A, prolifera existed in southeastern Florida during the late Holocene, confirming that Caribbean acroporid hybridization occurred prior to their region-wide die off in the 1970s and 1980s.
