This project aims to characterise the biogeographic constraints on the physiological flexibility of eucalypts to accommodate climate warming. Do temperature tolerances of diverse taxa vary predictably with native geographic range sizes and climate of origin? In addressing this question, the project expects to generate new knowledge on the comparative physiological responses of diverse eucalypt taxa to warming and heat waves using controlled-environment studies and a unique facility at Western Sydney University for heat wave studies of large trees. Expected outcomes include an enhanced capacity to predict carbon exchange and growth responses of native trees to climate warming over large geographic scales.

该项目旨在描述桉树适应气候变暖的生理灵活性所受的生物地理限制。不同类群的温度耐受性是否可预测地随原产地的地理范围、大小和气候而变化？为了解决这个问题，该项目希望通过受控环境研究和西悉尼大学一个独特的大树热浪研究设施，产生关于不同桉树分类群对升温和热浪的比较生理反应的新知识。预期成果包括提高预测碳交换的能力，以及在大地理范围内本土树木对气候变暖的生长反应。
