珊瑚招募描述了种群中新的个体的增加，这是促成种群规模的最基本的人口过程之一。由于世界各地的许多珊瑚礁都经历了珊瑚覆盖率和丰富度的大幅下降，人们非常有兴趣了解导致珊瑚招募不同的因素以及在什么条件下珊瑚招募可以支持社区的复原力。虽然技术和科学进步促进了这些领域的进展，但衡量招募人数的最好工具之一仍然是简陋的定居点瓷砖，其变体已经使用了一个多世纪。在这里，我回顾了珊瑚新兵的生物学和生态学，以及主要通过使用聚落瓷砖解决的招募过程，方法是：(I)定义如何使用‘招募’和‘招募’两个术语，并解释为什么松散的术语阻碍了科学进步；(Ii)描述如何衡量珊瑚招募以及为什么定居瓷砖对此有价值；(Iii)总结以前审查珊瑚招募定量分析的努力；(Iv)描述假说驱动的研究在确定避难所、海水流动和食草动物如何调节珊瑚招募方面的进展；(V)审查小珊瑚(即新兵)的生物学，以更好地了解它们如何应对环境条件；以及(Vi)更新从1974年至今的珊瑚招募研究的量化汇编，从而揭示全球新兵密度的长期下降，同时对珊瑚漂白有明显的适应能力。最后，我回顾了珊瑚招募研究的未来方向，强调需要扩大研究以提供分类解决办法，并解释为什么定居点瓦片部署的时间序列在量化珊瑚招募方面可能仍然是关键。
Coral recruitment describes the addition of new individuals to populations, and it is one of the most fundamental demographic processes contributing to population size. As many coral reefs around the world have experienced large declines in coral cover and abundance, there has been great interest in understanding the factors causing coral recruitment to vary and the conditions under which it can support community resilience. While progress in these areas is being facilitated by technological and scientific advances, one of the best tools to quantify recruitment remains the humble settlement tile, variants of which have been in use for over a century. Here I review the biology and ecology of coral recruits and the recruitment process, largely as resolved through the use of settlement tiles, by: (i) defining how the terms ‘recruit’ and ‘recruitment’ have been used, and explaining why loose terminology has impeded scientific advancement; (ii) describing how coral recruitment is measured and why settlement tiles have value for this purpose; (iii) summarizing previous efforts to review quantitative analyses of coral recruitment; (iv) describing advances from hypothesis‐driven studies in determining how refuges, seawater flow, and grazers can modulate coral recruitment; (v) reviewing the biology of small corals (i.e. recruits) to understand better how they respond to environmental conditions; and (vi) updating a quantitative compilation of coral recruitment studies extending from 1974 to present, thus revealing long‐term global declines in density of recruits, juxtaposed with apparent resilience to coral bleaching. Finally, I review future directions in the study of coral recruitment, and highlight the need to expand studies to deliver taxonomic resolution, and explain why time series of settlement tile deployments are likely to remain pivotal in quantifying coral recruitment.
