Global ocean warming is affecting keystone species distributions and fitness, resulting in the degradation of marine ecosystems. Coral reefs are one of the most diverse and productive marine ecosystems. However, reef-building corals, the foundational taxa of coral reef ecosystems, are severely threatened by thermal stress. Models predict 40-80% of global coral cover will be lost by 2100, which highlights the urgent need for widespread interventions to preserve coral reef functionality. There has been extensive research on coral thermal stress and resilience, but 95% of studies have focused on adult corals. It is necessary to understand stress during early life stages (larvae, recruits, and juveniles), which will better inform selective breeding programs that aim to replenish reefs with resilient stock. In this review, we surveyed the literature on coral thermal resilience in early life stages, and we highlight that studies have been conducted on relatively few species (commonly Acropora spp.) and in limited regions (mainly Australia). Reef-building coral management will be improved by comprehensively understanding coral thermal resilience and fitness across life stages, as well as in diverse species and regions.
全球海洋变暖正在影响关键物种的分布和适应性，导致海洋生态系统退化。珊瑚礁是最多样化和生产力最高的海洋生态系统之一。然而，珊瑚礁的基础生物珊瑚属中的造礁珊瑚受到热应激的严重威胁。模型预测，到 2100 年，全球珊瑚覆盖率将有 40%-80%丧失，这凸显了广泛干预以保护珊瑚礁功能的迫切需要。已经有大量关于珊瑚热应激和恢复力的研究，但 95%的研究都集中在成年珊瑚上。有必要了解早期生命阶段（幼虫、幼体和青少年）的应激情况，这将更好地为旨在用有恢复力的种群补充珊瑚礁的选择性繁殖计划提供信息。在这篇综述中，我们调查了早期生命阶段珊瑚热恢复力的文献，并强调了研究主要集中在少数几个物种（通常是鹿角珊瑚属）和有限的区域（主要是澳大利亚）。全面了解珊瑚在不同生命阶段、不同物种和不同地区的热恢复力和适应性，将有助于改善造礁珊瑚的管理。
