This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host and symbiont response to changing water temperature along a latitudinal gradient. The intended outcome of the project is to provide knowledge to support predictions of likely species migrations from tropical to subtropical waters, enabling managers to anticipate the future response of coral communities to seawater warming.

该项目旨在发现澳大利亚珊瑚礁珊瑚能够生活在其范围边缘附近相对凉爽的水中的潜在特征。随着海洋温度变暖，新的群落预计将在高纬度生态系统中发展，这可能成为低纬度珊瑚礁的重要避难所。该项目旨在测试元素成分（碳、氮和磷）在珊瑚宿主中的作用以及共生体对沿纬度梯度变化的水温的反应。该项目的预期成果是提供知识来支持预测可能的物种从热带到亚热带水域的迁移，使管理人员能够预测珊瑚群落对海水变暖的未来反应。
