ABSTRACT: Research on coral reproduction has increased dramatically in recent times; however, there remain significant regions, in particular high latitude reefs, where research is limited. For example, the reproductive biology of species in the coral assemblage at Hall Bank, a high latitude site (32° S) in southern Western Australia, remain unknown. Here, reproductive traits and the likely time of spawning for 12 of the approximately 16 species that occur at Hall Bank were established using histology between March 2009 and March 2011 at 7 discrete time points. Peak reproductive activity most likely occurs in February, as 7 of the 10 species sampled in this month had colonies with mature gametes. The sexuality, mode of larval development and transmission of symbionts were, as expected, consistent with previous work. The reproductive biology of the corals at Hall Bank is consistent with other regions of the Indo-Pacific, supporting the hypothesis that reproductive traits such as sexuality and mode of larval development are evolutionarily conserved and do not vary biogeographically.

Hall Bank的珊瑚繁殖，西澳大利亚的高纬度珊瑚群

摘要：近来有关珊瑚繁殖的研究急剧增加。但是，仍然存在大量研究受限的地区，特别是高纬度礁石。例如，在西澳大利亚州南部高纬度地点（32°S）霍尔银行的珊瑚群落中，物种的生殖生物学仍然未知。在这里，使用组织学方法，在2009年3月至2011年3月之间的7个离散时间点，确定了在霍尔银行发生的大约16个物种中的12个物种的生殖特性和可能的​​产卵时间。最高的繁殖活动可能发生在2月，因为本月采样的10个物种中有7个具有成熟配子的菌落。正如所料，性行为，幼体发育的方式和共生体的传播与以前的工作一致。
