与温带近岸系统类似，热带后礁系统的育苗范式是，它们为物种的幼体提供栖息地，这些幼体随后在珊瑚礁上进行个体发育转变为成年种群（我们将其称为后礁系统的育苗功能）。然而，我们对珊瑚礁后系统的育苗功能对维持珊瑚礁鱼类和无脊椎动物种群的重要性缺乏充分的了解；对多个生境的育苗功能进行考察的少数研究表明，对珊瑚礁后生境中幼体的生产与其随后对珊瑚礁上成年种群的贡献之间的关系仍然知之甚少。在本概要中，我们（1）综合了当前关于生活史、生态和栖息地对后礁系统内幼鱼分布模式和保育功能的影响的知识； (2) 概述评估后礁系统中各种生境类型的苗圃功能的研究策略； (3) 讨论管理建议，特别是关于如何在渔业和生态系统管理（包括栖息地保护和恢复决策）中利用对珊瑚礁后系统育苗功能的改进了解。该研究策略建立在评估温带栖息地苗圃功能的研究建议的基础上，包括4个层次的研究：（1）建立概念模型来指导研究和管理； (2) 确定幼体栖息地的使用模式； (3) 测量栖息地之间青少年和成人种群的连通性； (4) 检查可能影响 2 级和 3 级研究中评估的模式的生态过程。第一级至第四级的研究和建模输出将提供对珊瑚礁和邻近珊瑚礁系统之间相互联系的程度和重要性的更好的生态理解，并将向管理者提供信息，以促进有关栖息地保护、栖息地恢复和基于生态系统的管理以及可持续渔业维护的明智决策。
Similar to nearshore systems in temperate latitudes, the nursery paradigm for tropical back-reef systems is that they provide a habitat for juveniles of species that subsequently make ontogenetic shifts to adult populations on coral reefs (we refer to this as the nursery function of back-reef systems). Nevertheless, we lack a full understanding of the importance of the nursery function of back-reef systems to the maintenance of coral reef fishes and invertebrate populations; the few studies that have examined the nursery function of multiple habitats indicate that the relationship between juvenile production in back-reef habitats and their subsequent contribution to adult populations on reefs remain poorly understood. In this synopsis we (1) synthesize current knowledge of life history, ecological and habitat influences on juvenile distribution patterns and nursery function within back-reef systems; (2) outline a research strategy for assessing the nursery function of various habitat types in back-reef systems; and (3) discuss management recommendations, particularly in regard to how improved knowledge of the nursery function of back-reef systems can be used in fisheries and ecosystem management, including habitat conservation and restoration decisions. The research strategy builds on research recommendations for assessing the nursery function of temperate habitats and includes 4 levels of research: (1) building conceptual models to guide research and management; (2) identifying juvenile habitat use patterns; (3) measuring connectivity of juvenile and adult populations between habitats; and (4) examining ecological processes that may influence patterns assessed in Level 2 and Level 3 research. Research and modeling output from Levels 1 to 4 will provide an improved ecological understanding of the degree and importance of interconnections between coral reef and adjacent back-reef systems, and will provide information to managers that will facilitate wise decisions pertaining to habitat conservation, habitat restoration, and ecosystem-based management, and the maintenance of sustainable fisheries.
