珊瑚礁是地球上最多样化和最具生产力的生态系统之一。石珊瑚作为主要的珊瑚礁生态系统工程师，构建了为所有其他与珊瑚礁相关的生物提供栖息地的框架。然而，珊瑚的这种工程作用特别容易受到全球气候变化的影响。海洋变暖会导致大量珊瑚大规模白化，这会引发主要工程过程的功能失调。亚致死性白化会导致初级生产力和珊瑚钙化作用降低。这可能导致有机和无机产物释放的变化，从而改变珊瑚礁生态系统中关键的生物地球化学和循环过程。热应激导致的白化以及随后的珊瑚死亡，再加上海洋酸化，进一步导致底栖生物群落结构的长期改变、珊瑚礁地形复杂性的变化以及珊瑚礁功能的改变。这种变化可能会引起负反馈循环，并进一步改变珊瑚产生的无机和有机产物。这篇综述强调了石珊瑚作为珊瑚礁生态系统工程师的关键作用，并突出了珊瑚对关键的珊瑚礁生态系统产品和服务的控制，包括高生物多样性、海岸保护、渔业和旅游业。因此，气候变化阻碍珊瑚生态系统工程师的作用将会损害整个珊瑚礁的生态系统功能。
Coral reefs are among the most diverse and productive ecosystems on our planet. Scleractinian corals function as the primary reef ecosystem engineers, constructing the framework that serves as a habitat for all other coral reef-associated organisms. However, the coral's engineering role is particularly susceptible to global climate change. Ocean warming can cause extensive mass coral bleaching, which triggers dysfunction of major engineering processes. Sub-lethal bleaching results in the reduction of both primary productivity and coral calcification. This may lead to changes in the release of organic and inorganic products, thereby altering critical biogeochemical and recycling processes in reef ecosystems. Thermal stress-induced bleaching and subsequent coral mortality, along with ocean acidification, further lead to long-term shifts in benthic community structure, changes in topographic reef complexity, and the modification of reef functioning. Such shifts may cause negative feedback loops and further modification of coral-derived inorganic and organic products. This review emphasises the critical role of scleractinian corals as reef ecosystem engineers and highlights the control of corals over key reef ecosystem goods and services, including high biodiversity, coastal protection, fishing, and tourism. Thus, climate change by impeding coral ecosystem engineers will impair the ecosystem functioning of entire reefs.
