This project aims to trace the evolution of climate tolerance in conifers by combining evidence from fossils, phylogenies, physiology and mathematics. The project plans to use innovative methods to overcome the biases in methods currently used to trace evolutionary change. The project plans to integrate data from three sources: the global fossil record, new models of current climatic tolerances of conifers, and mathematical simulations of how and when methods of reconstructing ancestral ecology fail. The combined results should show how this important group of organisms has responded to past climate change and how they will respond in the future. It should also provide improved estimates of past terrestrial climates.

该项目旨在通过结合化石、系统发育、生理学和数学的证据来追踪针叶树的气候耐受性演变。该项目计划使用创新的方法来克服目前用于追踪进化变化的方法中的偏见。该项目计划整合来自三个来源的数据：全球化石记录，针叶树当前气候耐受性的新模型，以及重建祖先生态的方法如何以及何时失败的数学模拟。综合结果应该显示出这一重要的生物群体如何对过去的气候变化做出反应，以及它们将如何在未来做出反应。它还应该提供对过去陆地气候的改进估计。
