随着气候变化在全球范围内造成灾难性的珊瑚礁损失，珊瑚礁已经进入了一个“生态危机”的时代。珊瑚的生长和应激敏感性受其内共生甲藻(共生藻属)的调节。共生纲的系统发育多样性通常与珊瑚的健康和生存模式相对应，但功能多样性的知识对于协调更广泛的生态成功在空间和时间上是最终必要的。我们在这里探索支撑共生生物复杂生物学的功能特征，这种共生生物横跨自由生活的藻类到珊瑚内共生体。为此，我们提出了一个机制框架，整合了资源获取和利用的主要特征，作为解释共生生物功能多样性和解决共生生物在不确定未来下推动珊瑚礁稳定性的作用的一种手段。
Coral reefs have entered an era of ‘ecological crisis' as climate change drives catastrophic reef loss worldwide. Coral growth and stress susceptibility are regulated by their endosymbiotic dinoflagellates (genusSymbiodinium). The phylogenetic diversity ofSymbiodiniumfrequently corresponds to patterns of coral health and survival, but knowledge of functional diversity is ultimately necessary to reconcile broader ecological success over space and time. We explore here functional traits underpinning the complex biology ofSymbiodiniumthat spans free-living algae to coral endosymbionts. In doing so we propose a mechanistic framework integrating the primary traits of resource acquisition and utilisation as a means to explainSymbiodiniumfunctional diversity and to resolve the role ofSymbiodiniumin driving the stability of coral reefs under an uncertain future.
