Drs. Baker and Langdon will investigate the threats of climate change on coral reef ecosystems by analyzing the effects of high-temperature stress on reef-building coral-algal symbioses and the impacts of increased atmospheric CO2 (pCO2) on the ability of scleractinian (stony) corals to effectively calcify and build reefs in shallow tropical seas at increasingly low aragonite saturation states. This project uses a controlled outdoor experimental laboratory to investigate the responses of a suite of common coral species from the tropical western Atlantic (Caribbean) to the combined effects of high pCO2 and high temperature. The investigators will study photosynthesis, calcification, bleaching and symbiont community structure for these corals in response to a variety of experimental treatments that fall within the scope of conservative climate expectations. The investigators will use these results to identify potential species survival trajectories and changes in reef coral community composition for Caribbean coral reefs over the next 30- 50 years. The broader impacts of these studies are diverse: understanding and predicting changes in coral reef communities, enhancing local research infrastructure at the University of Miami, training and involvement for high-school, undergraduate, and graduate students, and training for a postdoctoral associate.

贝克和兰登将调查气候变化对珊瑚礁生态系统的威胁，通过分析高温应力对造礁珊瑚藻共生的影响，以及大气二氧化碳（pCO 2）增加对石珊瑚（石珊瑚）的影响。 该项目使用一个受控的室外实验室，调查热带西大西洋（加勒比）的一套常见的珊瑚物种对高pCO 2和高温的综合影响的反应。研究人员将研究这些珊瑚的光合作用，钙化，漂白和共生体群落结构，以应对属于保守气候预期范围内的各种实验处理。 研究人员将利用这些结果来确定未来30- 50年加勒比珊瑚礁的潜在物种生存轨迹和珊瑚礁群落组成的变化。 这些研究的更广泛的影响是多种多样的：了解和预测珊瑚礁群落的变化，加强当地的研究基础设施在迈阿密大学，培训和高中，本科生和研究生的参与，并为博士后助理培训。
