To improve coral reef management, a deeper understanding of biodiversity across scales in the context of functional groups is required. The focus of this paper is on the role of diversity within functional groups in securing important ecosystem processes that contribute to the resilience of coral-dominated reef states. Two important components of species biodiversity that confer ecosystem resilience are analyzed: redundancy and the diversity of responses within functional groups to change. Three critical functional groups are used to illustrate the interaction between these two components and their role in coral reef resilience: zooxanthellae (symbiotic micro algae in reef-building corals), reef-building corals, and herbivores. The paper further examines the consequences of undermining functional redundancy and response diversity and addresses strategies to secure ecological processes that are critical for coral reef resilience.
为改善珊瑚礁管理，需要在功能群背景下更深入地了解不同尺度的生物多样性。本文重点关注功能群内多样性在保障重要生态系统过程中的作用，这些过程有助于以珊瑚为主导的礁体状态的恢复力。分析了赋予生态系统恢复力的物种生物多样性的两个重要组成部分：冗余性以及功能群内对变化的响应多样性。使用三个关键功能群来说明这两个组成部分之间的相互作用及其在珊瑚礁恢复力中的作用：虫黄藻（造礁珊瑚中的共生微藻）、造礁珊瑚和食草动物。本文进一步探讨了破坏功能冗余性和响应多样性的后果，并阐述了保障对珊瑚礁恢复力至关重要的生态过程的策略。
