Corals form the architectural framework for tropical reefs, supporting the most productive and biologically diverse marine ecosystems on Earth. Because coral reefs are especially vulnerable, it is important to understand how organisms and populations can respond to ocean warming either through range expansion, physiological acclimatization, or genetic adaptation. At the Central Caribbean Marine Institute in the Cayman Islands, data collected continuously over the last 22 years offers a long-term ecological record of thereefs and provides insight into the recent performance of the local reef ecosystem and impacts of global stress events, such as coral bleaching. This long-term dataset can provide unique insight and evidence of resilience capacity of coral reefs in the region and potentially globally. This award will leverage this research history with infrastructure to study the physiological and molecular mechanisms that drive resilience of coral reef systems. It will provide a much-needed opportunity for scientists to disentangle anthropogenic and climate influences on coral reef evolution, adaption, and resilience at all levels of the ecosystem, from species and community levels to genomic and microbial levels. The new infrastructure consists of an outdoor mesocosm in which environmental parameters can be modified independently for manipulative experiments, and an adjacent molecular laboratory that will enable preservation, extraction and processing of experimental samples. Current research on the mechanisms driving coral reef ecosystem and organismal adaptation and evolution during climate stress and extreme will be advanced by the capacity to experimentally manipulate environmental conditions, such as light and temperature, as well as access to a molecular facility to process and preserve samples for genomic comparisons. Resources that enable manipulative experiments and molecular analyses, will attract visiting researchers to examine questions related to reef resilience and adaptation in collaboration with resident scientists at CCMI. Public outreach and educational programs serving undergraduate and graduate level students will be expanded by the new infrastructure.

珊瑚构成了热带礁石的建筑框架，支持地球上生产力最多样化的海洋生态系统。由于珊瑚礁特别容易受到伤害，因此重要的是要了解生物和种群如何通过扩展，生理适应或遗传适应来对海洋变暖的反应。在开曼群岛的中部加勒比海陆战队研究所，在过去22年中不断收集的数据提供了其长期生态记录，并洞悉了当地珊瑚礁生态系统的最新表现以及全球压力事件的影响，例如珊瑚漂白。这个长期数据集可以提供独特的见解和证据，证明该地区乃至全球珊瑚礁的弹性能力。该奖项将利用基础设施来利用这一研究历史来研究推动珊瑚礁系统弹性的生理和分子机制。它将为科学家提供一个急需的机会，以消除人类学和气候对珊瑚礁进化，适应和弹性的影响，从物种和社区水平到基因组和微生物水平。新的基础设施由一个室外中验组成，其中可以独立修改环境参数以进行操纵实验，以及一个相邻的分子实验室，该实验室将实现实验样品的保存，提取和处理。当前对驱动珊瑚礁生态系统以及在气候压力和极端情况的机制的研究将通过实验操纵环境条件（例如光和温度）以及进入分子设施来处理并保留基因组比较样品的分子设施，以进行实验性的环境条件。能够实现操纵实验和分子分析的资源将吸引来访的研究人员研究与CCMI的常驻科学家合作的与珊瑚礁弹性和适应有关的问题。新的基础设施将扩大服务本科生和研究生级学生的公共宣传和教育计划。有关CMMI的更多信息，请访问https://reefresearch.org/. This Award反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估标准通过评估来支持的。
