In recent decades, the Florida reef tract has lost over 95% of its coral cover. Although isolated coral assemblages persist, coral restoration programs are attempting to recover local coral populations. Listed as threatened under the Endangered Species Act, Acropora cervicornis is the most widely targeted coral species for restoration in Florida. Yet strategies are still maturing to enhance the survival of nursery‐reared outplants of A. cervicornis colonies on natural reefs. This study examined the survival of 22,634 A. cervicornis colonies raised in nurseries along the Florida reef tract and outplanted to six reef habitats in seven geographical subregions between 2012 and 2018. A Cox proportional hazards regression was used within a Bayesian framework to examine the effects of seven variables: (1) coral‐colony size at outplanting, (2) coral‐colony attachment method, (3) genotypic diversity of outplanted A. cervicornis clusters, (4) reef habitat, (5) geographical subregion, (6) latitude, and (7) the year of monitoring. The best models included coral‐colony size at outplanting, reef habitat, geographical subregion, and the year of monitoring. Survival was highest when colonies were larger than 15 cm (total linear extension), when outplanted to back‐reef and fore‐reef habitats, and when outplanted in Biscayne Bay and Broward–Miami subregions, in the higher latitudes of the Florida reef tract. This study points to several variables that influence the survival of outplanted A. cervicornis colonies and highlights a need to refine restoration strategies to help restore their population along the Florida reef tract.

佛罗里达礁石带育苗的鹿角刺足科植物外植体的差异存活率

在最近的几十年中，佛罗里达的珊瑚礁已经失去了95％的珊瑚覆盖率。尽管孤立的珊瑚群仍然存在，但珊瑚恢复计划正在尝试恢复当地的珊瑚种群。根据《濒危物种法》的规定，Acropora cervicornis被定为佛罗里达州恢复目标最广泛的珊瑚物种。然而，提高育苗场天然珊瑚礁上A. cervicornis菌落的外植体存活率的策略仍在成熟。这项研究检查了22634头宫颈曲霉的存活在2012年至2018年之间，佛罗里达州沿珊瑚礁的苗圃中培育出了一些集落，并移栽到七个地理分区的六个礁石栖息地。在贝叶斯框架内使用Cox比例风险回归研究了七个变量的影响：（1）珊瑚殖民地的规模外植时，（2）珊瑚菌落附着法，（3）外植A. cervicornis的基因型多样性集群，（4）珊瑚礁栖息地，（5）地理分区，（6）纬度和（7）监测年。最好的模型包括外植，珊瑚栖息地，地理区域和监测年份的珊瑚群大小。当菌落大于15 cm（总线性延伸），移栽到后礁和前礁栖息地以及在比斯坎湾和Broward-Miami次区域移出佛罗里达礁区高纬度地区时，存活率最高。该研究指出，影响outplanted生存的几个变量A. cervicornis殖民地和亮点需要进一步完善恢复策略，以帮助沿着佛罗里达珊瑚礁道恢复他们的人口。
