"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."Tropical coral reefs face a suite of environmental assaults ranging from anchor damage to the effects of global climate change (GCC). The consequences are evident throughout the tropics, where many coral reefs have lost a substantial fraction of their coral cover in a few decades. Notwithstanding the importance of reducing the impacts of environmental stresses, the only means by which these ecosystems can recover (or simply persist) is through the recruitment of scleractinians, which is a function of successful larval development, delivery, settlement, metamorphosis, and post-settlement events. Despite wide recognition of the importance of these processes, there are few pertinent empirical data, and virtually none that address the mechanisms mediating the success of early coral life stages in a physical environmental varying at multiple spatio-temporal scales. The objective of this research is to complete one of the first comprehensive ecophysiological analyses of the early life stages of corals through a description of: (1) their functionality under 'normal' conditions, and (2) their response to the main drivers of GCC. These analyses will be completed for 2 species representative of a brooding life history strategy, and the experiments will be completed in two locations, one (Taiwan) that provides unrivalled experience in coral reproductive biology, and superb microcosm facilities, and the other (Moorea), with access to a relatively pristine environment, a well described ecological and oceanographic context (through the MCR-LTER), and the capacity to bring a strong biogeographic contrast to the project. The results of the study will be integrated through modeling to explore the effects of GCC on coral community structure over the next century. The broader impacts include training and research opportunities to teachers, undergraduates, and high school students in a diverse community, international training and activities for students in Taiwan and Moorea, and involvement in the Three Seas Marine Biology Program. The Three Seas Marine Biology Program provides a channel for the rapid incorporation of results in the curriculum for advanced undergraduates, opportunities for teaching and student advising by project personnel, and the potential to recruit top students into the CSUN graduate program.

“该奖项是根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金的。”热带珊瑚礁面临着一系列环境攻击，从锚点损坏到全球气候变化 (GCC) 的影响。其后果在整个热带地区都很明显，许多珊瑚礁在几十年内失去了大部分珊瑚覆盖。尽管减少环境压力的影响很重要，但这些生态系统恢复（或简单地持续）的唯一方法是通过招募石珊瑚，这是幼虫成功发育、交付、定居、变态和后期的功能。结算事件。尽管人们广泛认识到这些过程的重要性，但几乎没有相关的经验数据，而且几乎没有任何数据能够解决在多个时空尺度变化的物理环境中调节早期珊瑚生命阶段成功的机制。这项研究的目的是通过描述以下内容，完成珊瑚早期生命阶段的第一个全面的生态生理学分析：(1) 它们在“正常”条件下的功能，以及 (2) 它们对海湾合作委员会主要驱动因素的反应。这些分析将针对代表育雏生活史策略的 2 个物种完成，实验将在两个地点完成，一处（台湾），在珊瑚繁殖生物学方面提供无与伦比的经验和一流的微观设施，另一处（莫雷阿岛） ，能够获得相对原始的环境、良好描述的生态和海洋背景（通过 MCR-LTER），以及为项目带来强烈的生物地理对比的能力。研究结果将通过建模进行整合，以探索海湾合作委员会对下个世纪珊瑚群落结构的影响。更广泛的影响包括为教师、本科生和高中生在多元化社区提供培训和研究机会，为台湾和莫雷阿岛的学生提供国际培训和活动，以及参与三海海洋生物学计划。 三海海洋生物学项目提供了一个将成果快速纳入高年级本科生课程的渠道、项目人员的教学和学生咨询机会以及招收顶尖学生进入 CSUN 研究生项目的潜力。
