This research will greatly assist in predictions of future net carbon exchange that are necessary if Australia is to better manage its vegetation resources. Crucial to predicting future rates of net carbon exchange is an understanding of how drought and long-term changes in temperature impact on plant respiration. Using laboratory and field studies, this research will develop an understanding of how water availability and temperature impact on plant respiration of a broad range of economically important and ecologically relevant plant species. Equations will be formulated that allow modellers to better predict drought-dependent variations in plant respiration (and thus plant productivity), both now and in a future, warmer world.

这项研究将极大地有助于预测未来的净碳交换，如果澳大利亚要更好地管理其植被资源，这是必要的。预测未来净碳交换率的关键是了解干旱和长期温度变化如何影响植物呼吸。通过实验室和实地研究，本研究将了解水的可用性和温度如何影响广泛的经济重要性和生态相关植物物种的植物呼吸。 将制定方程，使建模者能够更好地预测干旱依赖的变化，植物呼吸（从而植物生产力），无论是现在和未来，更温暖的世界。
