Pushing the envelope: does range size limit eucalypt tolerance to warming?

该项目旨在揭示生态地理学对真核生物适应气候变暖的生理灵活性的限制。不同类群的温度耐受性是否随原生地理分布范围大小和原产地气候而变化？在解决这一问题时，该项目预计将产生新的知识，对不同的桉树类群的比较生理反应，以变暖和热浪使用受控环境的研究和独特的设施，在西悉尼大学的热浪研究的大树。预期成果包括提高能力，以预测大地理范围内的碳交换和本地树木对气候变暖的生长反应。

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.
