Predicting future net carbon exchange is necessary for better management of vegetation resources by Australia. Incorporating the responses of plant respiration to drought and temperature is crucial for predicting future rates of net carbon exchange. 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 will improve how modellers calculate drought-dependent variations in plant respiration (and thus plant productivity), thereby improving predictions for a future, warmer world.

预测未来的净碳交换对于澳大利亚更好地管理植被资源是必要的。结合植物呼吸对干旱和温度的响应对于预测未来的净碳交换率至关重要。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上重要的和生态相关的植物物种的植物呼吸。将制定方程，以改进建模者如何计算植物呼吸作用（从而提高植物生产力）的干旱依赖性变化，从而改进对未来变暖世界的预测。
