摘要
对多尺度功能群生物多样性的深入了解有助于珊瑚礁管理的加强。本文主要分析了功能群内多样性在保护有利于珊瑚礁状况复原的重要生态系统过程中的作用。对于与生态系统复原有关的两个重要的物种多样性指标：功能丰余性和功能群内对变化的反应多样性进行了分析，采用了三个重要的功能群来演示这两个指标之间的相互关系．以及它们在珊瑚礁复原过程中的作用：虫黄藻（珊瑚虫的共生微藻）、造礁珊瑚和草食动物。对功能丰余性和反应多样性破坏的后果进行了进一步研究，对保护珊瑚礁复原过程中关键的生态过程策略进行了探讨。
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 ecsystem 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 redun- dancy and response diversity and addresses strategies to secure ecological processes that are critical for coral reef resilience.
