Coral reef restoration is an attractive tool for the management of degraded reefs; however, conventional restoration approaches will not be effective under climate change. More proactive restoration approaches must integrate future environmental conditions into project design to ensure long-term viability of restored corals during worsening bleaching events. Corals exist along a continuum of stress-tolerant phenotypes that can be leveraged to enhance the thermal resilience of reefs through selective propagation of heat-tolerant colonies. Several strategies for selecting thermally tolerant stock are currently available and range broadly in scalability, cost, reproducibility, and specificity. Different components of the coral holobiont have different utility to practitioners as diagnostics and drivers of long-term phenotypes, so selection strategies can be tailored to the resources and goals of individual projects. There are numerous unknowns and potential trade-offs to consider, but we argue that a focus on thermal tolerance is critical because corals that do not survive bleaching cannot contribute to future reef communities at all. Selective propagation uses extant corals and can be practically incorporated into existing restoration frameworks, putting researchers in a position to perform empirical tests and field trials now while there is still a window to act.

选择耐热珊瑚主动修复珊瑚

珊瑚礁修复是管理退化珊瑚礁的有吸引力的工具。但是，传统的恢复方法在气候变化下将不会有效。更加积极主动的修复方法必须将未来的环境条件整合到项目设计中，以确保在恶化的漂白事件中修复的珊瑚能够长期生存。珊瑚沿着耐压表型的连续体存在，可以通过选择性繁殖耐高温菌落来增强珊瑚的热弹性。当前有几种选择耐热材料的策略，其可扩展性，成本，可重复性和特异性广泛。珊瑚整体生物的不同组成部分对从业者作为长期表型的诊断和驱动因素具有不同的用途，因此可以根据单个项目的资源和目标量身定制选择策略。有许多未知因素和潜在的折衷考虑，但我们认为，对热耐受性的关注至关重要，因为不能幸免于漂白的珊瑚根本无法为未来的珊瑚礁群落做出贡献。选择性繁殖使用了现存的珊瑚，实际上可以纳入现有的恢复框架中，使研究人员现在可以进行经验测试和现场试验，同时还有行动的余地。
